The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Investments in registered open-end investment companies are valued at net asset value. Interests in non-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Foreign currency translation

The accounting records of the Portfolio are maintained in U.S. dollars. The values of other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee. Purchases and sales of securities, and income and expenses are converted at the rate of exchange on the respective dates of such transactions. Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually paid or received. Net unrealized foreign exchange gains and losses arise from changes in the fair value of assets and liabilities other than investments in securities resulting from changes in exchange rates. The changes in net assets arising from changes in exchange rates of securities and the changes in net assets resulting from changes in market prices of securities are not separately presented. Such changes are included in net realized and unrealized gains or losses from investments.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value

Notes to financial statements (unaudited) Wells Fargo Diversified Large Cap Growth Portfolio 15

of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Portfolio”). The Securities Lending Portfolio is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Portfolios Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Portfolios Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Portfolios Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Portfolio increase. All of the fees received by Portfolios Management are paid to WellsCap for its services as subadviser. The Securities Lending Portfolio seeks to provide a positive return compared to the daily Fed Portfolios Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Portfolio investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Portfolio, if any, is included in income from affiliated securities on the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on the ex-dividend date. Dividend income is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $356,568,633 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	45,099,363
Gross unrealized losses		(10,133,179	)
Net unrealized gains	$	34,966,184

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

At November 30, 2018, the Portfolio did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible for day-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.65% and declining to 0.475% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.65% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. WellsCap is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.30% and declining to 0.20% as the average daily net assets of the Portfolio increase.

Funds Management has voluntarily waived and/or reimbursed advisory fees to the extent necessary to maintain the net operating expense ratio of the Portfolio.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $400,710,700 and $110,695,655, respectively.

Notes to financial statements (unaudited) Wells Fargo Diversified Large Cap Growth Portfolio 17

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. CONCENTRATION RISK

Concentration risks result from exposure to a limited number of sectors. A portfolio that invests a substantial portion of its assets in any sector may be more affected by changes in that sector than would be a portfolio whose investments are not heavily weighted in any sector.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

Notes to financial statements (unaudited) Wells Fargo Disciplined Large Cap Portfolio 17

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Disciplined Large Cap Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Investments in registered open-end investment companies are valued at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on the ex-dividend date. Dividend income is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the fiscal year are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

18 Wells Fargo Disciplined Large Cap Portfolio Notes to financial statements (unaudited)

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $399,571,398 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	17,564,467
Gross unrealized losses		(24,973,097	)
Net unrealized loss	$	(7,408,630	)

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible for day-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.25% and declining to 0.20% as the average daily net assets of the Portfolio increase. For the period ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.25% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. Wells Capital Management Incorporated, an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.20% and declining to 0.15% as the average daily net assets of the Portfolio increase.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the period ended November 30, 2018 were $577,291,691 and $174,451,911, respectively.

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the period ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

8. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

Notes to financial statements (unaudited) Wells Fargo International Growth Portfolio 11

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo International Growth Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

The values of securities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”).

Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange and therefore may not fully reflect trading or events that occur after the close of the principal exchange in which the foreign securities are traded, but before the close of the New York Stock Exchange. If such trading or events are expected to materially affect the value of such securities, then fair value pricing procedures approved by the Board of Trustees of the Portfolio are applied. These procedures take into account multiple factors including movements in U.S. securities markets after foreign exchanges close. Foreign securities that are fair valued under these procedures are categorized as Level 2 and the application of these procedures may result in transfers between Level 1 and Level 2. Depending on market activity, such fair valuations may be frequent. Such fair value pricing may result in net asset values that are higher or lower than net asset values based on the last reported sales price or latest quoted bid price. On November 30, 2018, such fair value pricing was not used in pricing foreign securities.

Investments in registered open-end investment companies are valued at net asset value. Interests in non-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee. The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Foreign currency translation

The accounting records of the Portfolio are maintained in U.S. dollars. The values of other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee. Purchases and sales of securities, and income and expenses are converted at the rate of exchange on the respective dates of such transactions. Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually paid or received. Net unrealized foreign exchange gains and losses arise from changes in the fair value of assets and liabilities other than investments in securities

12 Wells Fargo International Growth Portfolio Notes to financial statements (unaudited)

resulting from changes in exchange rates. The changes in net assets arising from changes in exchange rates of securities and the changes in net assets resulting from changes in market prices of securities are not separately presented. Such changes are included in net realized and unrealized gains or losses from investments.

Participation notes

The Portfolio may invest in participation notes to gain exposure to securities in certain foreign markets. Participation notes are issued by banks or broker-dealers and are designed to offer a return linked to a particular underlying foreign security. Participation notes involve transaction costs, which may be higher than those applicable to the underlying foreign security. The holder of the participation note is entitled to receive from the bank or broker-dealer, an amount equal to the dividend paid by the issuer of the underlying foreign security; however, the holder is not entitled to the same rights (i.e. voting rights) as an owner of the underlying foreign security. Investments in participation notes involve risks beyond those normally associated with a direct investment in an underlying security. The Portfolio has no rights against the issuer of the underlying foreign security and participation notes expose the Portfolio to counterparty risk in the event the counterparty does not perform. There is also no assurance there will be a secondary trading market for the participation note or that the trading price of the participation note will equal the underlying value of the foreign security that it seeks to replicate.

Forward foreign currency contracts

The Portfolio is subject to foreign currency risk in the normal course of pursuing its investment objectives. A forward foreign currency contract is an agreement between two parties to purchase or sell a specific currency for an agreed-upon price at a future date. The Portfolio enters into forward foreign currency contracts to facilitate transactions in foreign-denominated securities and to attempt to minimize the risk to the Portfolio from adverse changes in the relationship between currencies. Forward foreign currency contracts are recorded at the forward rate and marked-to-market daily. When the contracts are closed, realized gains and losses arising from such transactions are recorded as realized gains or losses on forward foreign currency contracts. The Portfolio could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts or if the value of the foreign currency changes unfavorably. The Portfolio’s maximum risk of loss from counterparty credit risk is the unrealized gains on the contracts. This risk may be mitigated if there is a master netting arrangement between the Portfolio and the counterparty.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund, if any, is included in income from affiliated securities on the Statement of Operations.

Notes to financial statements (unaudited) Wells Fargo International Growth Portfolio 13

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on the ex-dividend date, except for certain dividends from foreign securities, which are recorded as soon as the custodian verifies the ex-dividend date. Dividend income from foreign securities is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $256,348,241 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	14,739,622
Gross unrealized losses		(13,080,113	)
Net unrealized gains	$	1,659,509

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

At November 30, 2018, the Portfolio did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES AND OTHER EXPENSES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible for day-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.80% and declining to 0.65% as the average daily net assets of the Portfolio increase. For the six months end November 30, 2018, the advisory fee was equivalent to an annual rate of 0.80% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. Artisan Partners, Limited Partnership, which is not an affiliate of Funds Management, is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.80% and declining to 0.50% as the average daily net assets of the Portfolio increase.

Funds Management has voluntarily waived and/or reimbursed advisory fees to the extent necessary to maintain the net operating expense ratio of the Portfolio.

Notes to financial statements (unaudited) Wells Fargo International Growth Portfolio 15

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $352,222,605 and $131,433,917, respectively.

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. CONCENTRATION RISK

Concentration risk result from exposure to a limited number of sectors. A portfolio that invests a substantial portion of its assets in any sector may be more affected by changes in that sector than would be a portfolio whose investments are not heavily weighted in any sector.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses.

12 Wells Fargo Large Company Value Portfolio Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Large Company Value Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities and futures contracts that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Investments in registered open-end investment companies are valued at net asset value.

Investments which are not valued using the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Futures contracts

The Portfolio is subject to equity price risk in the normal course of pursuing its investment objectives. Futures contracts are agreements between the Portfolio and a counterparty to buy or sell a specific amount of a commodity, financial instrument or currency at specified price and on a specified date. The Portfolio may buy and sell futures contracts in order to gain exposure to, or protect against, changes in security values. The primary risks associated with the use of futures contracts are the imperfect correlation between changes in market values of securities held by the Portfolio and the prices of futures contracts, and the possibility of an illiquid market. Futures contracts are generally entered into on a regulated futures exchange and cleared through a clearinghouse associated with the exchange. With futures contracts, there is minimal counterparty risk to the Portfolio since futures contracts are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures contracts against default.

Upon entering into a futures contracts, the Portfolio is required to deposit either cash or securities (initial margin) with the broker in an amount equal to a certain percentage of the contract value. Subsequent payments (variation margin) are paid to or from the broker each day equal to the daily changes in the contract value. Such payments are recorded as unrealized gains or losses and, if any, shown as variation margin receivable (payable) in the Statement of Assets and Liabilities. Should the Portfolio fail to make requested variation margin payments, the broker can gain access to the initial margin to satisfy the Portfolio’s payment obligations. When the contracts are closed, a realized gain or loss is recorded in the Statement of Operations.

Foreign currency translation

The accounting records of the Portfolio are maintained in U.S. dollars. The values of other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee. Purchases and sales of securities, and income and expenses are converted at the rate of exchange on the respective dates of such transactions. Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the

Notes to financial statements (unaudited) Wells Fargo Large Company Value Portfolio 13

trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually paid or received. Net unrealized foreign exchange gains and losses arise from changes in the fair value of assets and liabilities other than investments in securities resulting from changes in exchange rates. The changes in net assets arising from changes in exchange rates of securities and the changes in net assets resulting from changes in market prices of securities are not separately presented. Such changes are included in net realized and unrealized gains or losses from investments.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund, if any, is included in income from affiliated securities on the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on the ex-dividend date. Dividend income is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $281,481,575 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	14,480,745
Gross unrealized losses		(8,581,086	)
Net unrealized gains	$	5,899,659

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

Futures contracts are reported at their cumulative unrealized gains (losses) at measurement date as reported in the table following the Portfolio of Investments. For futures contracts, the current day’s variation margin is reported on the Statement of Assets and Liabilities. All other assets and liabilities are reported at their market value at measurement date.

At November 30, 2018, the Portfolio did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible for day-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to

Notes to financial statements (unaudited) Wells Fargo Large Company Value Portfolio 15

receive an annual advisory fee starting at 0.35% and declining to 0.30% as the average daily net assets of the Portfolio increase. For the six months end November 30, 2018, the advisory fee was equivalent to an annual rate of 0.35% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. WellsCap is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.25% and declining to 0.15% as the average daily net assets of the Portfolio increase. Prior to November 1, 2018, Analytic Investors, LLC, an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, was the subadviser for the Portfolio. On November 1, 2018, Analytic Investors, LLC was consolidated into WellsCap and WellsCap became the subadviser to the Portfolio. The consolidation did not result in any changes to the services provided to the Portfolio or to its strategy or fees and expenses.

Funds Management has voluntarily waived and/or reimbursed advisory fees to the extent necessary to maintain the net operating expense ratio of the Portfolio.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $ 539,970,759 and $ 322,473,140, respectively.

6. DERIVATIVE TRANSACTIONS

7. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Managed Fixed Income Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Debt securities are valued at the evaluated bid price provided by an independent pricing service service (e.g. taking into account various factors, including yields, maturities, or credit ratings) or, if a reliable price is not available, the quoted bid price from an independent broker-dealer.

Futures contracts that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price.

Investments in registeredopen-end investment companies are valued at net asset value. Interests innon-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management

receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund, if any, is included in income from affiliated securities on the Statement of Operations.

When-issued transactions

The Portfolio may purchase securities on a forward commitment or when-issued basis. The Portfolio records awhen-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Portfolio’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis aremarked-to-market daily and the Portfolio begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Futures contracts

The Fund is subject to interest rate risk in the normal course of pursuing its investment objectives. Futures contracts are agreements between the Fund and a counterparty to buy or sell a specific amount of a commodity, financial instrument or currency at specified price and on a specified date. The Fund may buy and sell futures contracts in order to gain exposure to, or protect against, changes in interest rates. The primary risks associated with the use of futures contracts are the imperfect correlation between changes in market values of securities held by the Fund and the prices of futures contracts, and the possibility of an illiquid market. Futures contracts are generally entered into on a regulated futures exchange and cleared through a clearinghouse associated with the exchange. With futures contracts, there is minimal counterparty risk to the Fund since futures contracts are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures contracts against default.

Upon entering into a futures contracts, the Fund is required to deposit either cash or securities (initial margin) with the broker in an amount equal to a certain percentage of the contract value. Subsequent payments (variation margin) are paid to or from the broker each day equal to the daily changes in the contract value. Such payments are recorded as unrealized gains or losses and, if any, shown as variation margin receivable (payable) in the Statement of Assets and Liabilities. Should the Fund fail to make requested variation margin payments, the broker can gain access to the initial margin to satisfy the Fund’s payment obligations. When the contracts are closed, a realized gain or loss is recorded in the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed onnon-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed fromnon-accrual status.

Income is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

28 Wells Fargo Managed Fixed Income Portfolio Notes to financial statements (unaudited)

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $671,151,800 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	1,745,827
Gross unrealized losses		(10,536,839	)
Net unrealized losses	$	(8,791,012	)

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total
Assets

At November 30, 2018, the Portfolio did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible forday-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.40% and declining to 0.29% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.40% of the Portfolio’s average daily net assets.

Notes to financial statements (unaudited) Wells Fargo Managed Fixed Income Portfolio 29

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. Galliard Capital Management, Inc., an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo, is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.20% and declining to 0.10% as the average daily net assets of the Portfolio increase.

Funds Management has voluntarily waived and/or reimbursed advisory fees to the extent necessary to maintain the net operating expense ratio of the Portfolio.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding short-term securities, for the six months ended November 30, 2018 were as follows:

Purchases at cost		Sales proceeds
U.S. government	Non-U.S. government	U.S. government	Non-U.S. government
$1,241,784,375	$449,216,032	$1,125,383,663	$19,223,731

6. DERIVATIVE TRANSACTIONS

The fair value, realized gains or losses and change in unrealized gains or losses, if any, on derivative instruments are reflected in the corresponding financial statement captions.

7. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo C&B Large Cap Value Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the third quarter of 2018.

Dear Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo C&B Large Cap Value Fund for thesix-month period that ended November 30, 2018. During the reporting period, the U.S. generated encouraging economic and business data that was offset by less positive and more inconsistent data from international markets. Investment returns were restrained in comparison with recent periods as geopolitical tensions and uncertainty tended to distract investors from more favorable underlying trends.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ gained 3.02% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 8.37%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 9.89%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ declined 0.30% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.67%. The Bloomberg Barclays Municipal Bond Index⁶ gained 0.42%. The ICE BofAML U.S. High Yield Index⁷ was up 0.19%.

Global trade tensions prompted investor concerns.

Global trade tensions escalated during the third quarter of 2018. The U.S. government’s decision during the second quarter to impose tariffs on a wide range of products manufactured overseas drew retaliatory responses from foreign governments, which punished U.S. commodity producers and product manufacturers. Investors were left to wonder about next steps in what appeared to be an escalating divergence in global economic policies and growth prospects.

Inflation trended higher. TheCPI-U⁸ added 0.1% in September after an increase of 0.2% in both July and August. On a year-over-year basis, theall-items index rose 2.3% for the 12 months that ended September 30, 2018, after a seasonal adjustment. The rate of increase was slower than that recorded during the first half of 2018. The index for all items less food and energy rose 2.2% for the same12-month period.

Letter to shareholders (unaudited) Wells Fargo C&B Large Cap Value Fund 3

U.S. stocks gained following positive economic data while international stocks and bonds declined.

During the summer months, the U.S. economy strengthened. Revised second-quarter gross domestic product (GDP) data released in August showed the U.S. economy growing at a 4.2% rate. The unemployment rate in the U.S. was 3.7% by the end of September, according to the U.S. Department of Labor. Wages showed more consistent growth, and consumer confidence remained strong. Several U.S. equity market indices reached records during August, with the S&P 500 Index gaining 7.20% for the three-month period that ended September 30, 2018. In contrast, the MSCI ACWI ex USA Index (Net) gained 0.71% while the MSCI EM Index (Net) declined 1.09% during the same three-month period.

In June, the Federal Reserve increased the target range for the federal funds rate to range from 1.75% to 2.00%. It raised the range again in September to range from 2.00% to 2.25%. Long-term interest rates in the U.S. remained at higher levels relative to the prior 10 years. Rates on10-year and30-year Treasury bonds—2.46% and 2.81%, respectively, on January 1, 2018—were 3.01% and 3.30%, respectively, on November 30, 2018. Investor concerns about an inverted yield curve reemerged, only to be replaced by concerns about the potentially negative influence of higher interest rates on economic activity.

November saw improvement in many equity markets.

As interest rates and bond yields gained during October, stock markets struggled. For the month, the S&P 500 Index fell 6.84%, the MSCI ACWI ex USA Index (Net) dropped 8.13%, and the MSCI EM Index (Net) lost 8.71%. The Bureau of Economic Analysis released its first estimate of third-quarter GDP, which, at an annualized 3.5% rate, indicated growth may be slowing compared with the second quarter. Readings on consumer sentiment and business spending were mixed. Markets rebounded somewhat in November as the S&P 500 Index gained 2.04%, the MSCI ACWI ex USA Index (Net) added 0.95%, and the MSCI EM Index (Net) was up 4.12% as the uncertainty leading up to midterm elections in the U.S. was resolved and progress seemed to be possible on several international trade issues.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began. In early August, the Bank of England’s Monetary Policy Committee increased its key interest rate to 0.75%. The European Central Bank and the Bank of Japan maintained low interest rates and accommodative monetary policies. Amid rising trade uncertainty, the People’s Bank of China cut reserve requirement ratios and accelerated infrastructure spending and tax cuts for business enterprises and individuals. Nevertheless, a strengthening U.S. dollar and the trade tensions remained headwinds for investors overseas.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the redemption of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance shown without sales charges would be lower if sales charges were reflected. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Current month-end performance is available on the Fund’s website,wellsfargofunds.com.

Index returns do not include transaction costs associated with buying and selling securities, any mutual fund fees or expenses, or any taxes. It is not possible to invest directly in an index.

For Class A shares, the maximum front-end sales charge is 5.75%. For Class C shares, the maximum contingent deferred sales charge is 1.00%. Performance including a contingent deferred sales charge assumes the sales charge for the corresponding time period. Class R6, Administrator Class, and Institutional Class shares are sold without a front-end sales charge or contingent deferred sales charge.

Stock values fluctuate in response to the activities of individual companies and general market and economic conditions. Consult the Fund’s prospectus for additional information on these and other risks.

¹  The Fund is a gateway feeder fund that invests substantially all of its assets in a single affiliated master portfolio of the Wells Fargo Master Trust with a substantially identical investment objective and substantially similar investment strategies. References to the investment activities of the Fund are intended to refer to the investment activities of the affiliated master portfolio in which it invests.

²  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

³  The manager has contractually committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s Total Annual Fund Operating Expenses After Fee Waivers at the amounts shown. Brokerage commissions, stamp duty fees, interest, taxes, acquired money market fund fees and expenses (if any) from funds in which the underlying master portfolio invests, and extraordinary expenses are excluded from the expense cap. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Net expenses from the underlying affiliated master portfolio are included in the expense cap. Without this cap, the Fund’s returns would have been lower. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁴  Historical performance shown for Class R6 shares prior to their inception reflects the performance of the Institutional Class shares adjusted to reflect the higher expenses applicable to Class R6 shares. If these expenses had been included, returns for Class R6 shares would be higher.

⁵  The Russell 1000^® Value Index measures the performance of those Russell 1000 companies with lower price/book ratios and lower forecasted growth values. You cannot invest directly in an index.

⁶  The ten largest holdings, excluding cash, cash equivalents and any money market funds, are calculated based on the value of the securities of the affiliated master portfolio allocable to the Fund divided by the total net assets of the Fund. Holdings are subject to change and may have changed since the date specified.

⁷  Amounts represent the sector distribution of the affiliated master portfolio which are calculated based on the total long-term investments of the affiliated master portfolio. These amounts are subject to change and may have changed since the date specified.

8 Wells Fargo C&B Large Cap Value Fund Fund expenses (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution (12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period from June 1, 2018 to November 30, 2018.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

¹ Amounts reflect net expenses allocated from the affiliated Master Portfolio in which the Fund invests.

² Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect the one-half-year period).

18 Wells Fargo C&B Large Cap Value Fund Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo C&B Large Cap Value Fund (the “Fund”) which is a diversified series of the Trust.

The Fund is a feeder fund in a master-feeder structure that invests substantially all of its assets in a single master portfolio with a substantially identical investment objective and substantially similar investment strategies. The Fund seeks to achieve its investment objective by investing all investable assets in a separate diversified portfolio (the “affiliated Master Portfolio”) of Wells Fargo Master Trust, a registered open-end management investment company. The affiliated Master Portfolio directly acquires portfolio securities and the Fund acquires an indirect interest in those securities. The Fund accounts for its investment in the affiliated Master Portfolio as a partnership investment and records on a daily basis its share of the affiliated Master Portfolio’s income, expense and realized and unrealized gains and losses. The financial statements of the affiliated Master Portfolio for the six months ended November 30, 2018 are included in this report and should be read in conjunction with the Fund’s financial statements. As of November 30, 2018, the Fund owned 78% of Wells Fargo C&B Large Cap Value Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation time under unusual or unexpected circumstances.

Investments in the affiliated Master Portfolio are valued daily based on the Fund’s proportionate share of the affiliated Master Portfolio’s net assets, which are also valued daily. Securities held in the affiliated Master Portfolio are valued as discussed in the Notes to Financial Statements of the affiliated Master Portfolio, which are included elsewhere in this report.

Investment transactions, income and expenses

Investments in the affiliated Master Portfolio are recorded on a trade basis.

The Fund records daily its proportionate share of the affiliated Master Portfolio’s interest and dividend income, expenses and realized and unrealized gains or losses. The Fund also accrues its own expenses.

Distributions to shareholders

Distributions to shareholders from net investment income and any net realized gains are recorded on the ex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Notes to financial statements (unaudited) Wells Fargo C&B Large Cap Value Fund 19

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $271,105,087 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	61,541,550
Gross unrealized losses		0
Net unrealized gains	$	61,541,550

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

At November 30, 2018, the affiliated Master Portfolio was measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The investment objective and the value of the affiliate Master Portfolio was as follows:

Affiliated Master Portfolio	Investment objective	Value of affiliated Master Portfolio
Wells Fargo C&B Large Cap Value Portfolio	Seeks maximum long-term total return (current income and capital appreciation), consistent with minimizing risk to principal		$332,646,637

The affiliated Master Portfolio does not have a redemption period notice, can be redeemed daily and does not have any unfunded commitments.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Wells Fargo Funds Management, LLC (“Funds Management”), an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As long as the Fund continues to invest substantially all of its assets in a single affiliated Master Portfolio, the Fund pays Funds Management an investment management fee only for fund-level administrative services at an annual rate starting at 0.05% and declining to 0.03% as the average daily net assets of the Fund increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.05% of the Fund’s average daily net assets.

Funds Management also serves as the adviser to the affiliated Master Portfolio and is entitled to receive a fee from the affiliated Master Portfolio for those services.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent, sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C		0.21	%
Class R6		0.03
Administrator Class, Institutional Class		0.13

20 Wells Fargo C&B Large Cap Value Fund Notes to financial statements (unaudited)

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Net expenses from the affiliated Master Portfolio are included in the expense cap. Funds Management has committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap each Fund’s expenses at 1.08% for Class A shares, 1.83% for Class C shares, 0.65% for Class R6 shares, 1.00% for Class Administrator Class shares and 0.75% for Institutional Class shares. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Distribution fee

The Trust has adopted a distribution plan for Class C shares of the Fund pursuant to Rule 12b-1 under the 1940 Act. A distribution fee is charged to Class C shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares.

In addition, Funds Distributor is entitled to receive the front-end sales charge from the purchase of Class A shares and a contingent deferred sales charge on the redemption of certain Class A shares. Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. For the six months ended November 30, 2018, Funds Distributor received $854 from the sale of Class A shares and $29 in contingent deferred sales charges from redemptions of Class C shares. No contingent deferred sales charges were incurred by Class A shares for the six months ended November 30, 2018.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Class C, and Administrator Class of the Fund are charged a fee at an annual rate of 0.25% of the average daily net assets of each respective class.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

5. INVESTMENT PORTFOLIO TRANSACTIONS

The Fund seeks to achieve its investment objective by investing substantially all of its investable assets in a single affiliated Master Portfolio. Purchases and sales have been calculated by multiplying the Fund’s ownership percentage of the affiliated Master Portfolio by the affiliated Master Portfolio’s purchases and sales. Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $103,695,875 and $75,798,561, respectively.

6. BANK BORROWINGS

The Trust (excluding the money market funds), Wells Fargo Master Trust and Wells Fargo Variable Trust are parties to a $280,000,000 revolving credit agreement whereby the Fund is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Fund based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Fund under the agreement.

7. DISTRIBUTIONS TO SHAREHOLDERS

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders. The amounts of distributions to shareholders for the year ended May 31, 2018 were as follows:

	Net investment income		Net realized gains
Class A	$	403,349	$	8,840,199
Class C		0		1,063,860
Class R6		36,739		416,469
Administrator Class		86,666		1,446,711
Institutional Class		2,028,817		25,953,214

Notes to financial statements (unaudited) Wells Fargo C&B Large Cap Value Fund 21

8. CONCENTRATION RISK

Concentration risk result from exposure to a limited number of sectors. Through its investment in the affiliated Master Portfolio which may invest a substantial portion of its assets in any sector, the Fund may in turn be more affected by changes in that sector than a fund whose investments are not heavily weighted in any sector.

9. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

10. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted.

30 Wells Fargo C&B Large Cap Value Portfolio Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo C&B Large Cap Value Portfolio (“C&B Large Cap Value Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Investments in registered open-end investment companies are valued at net asset value. Interests in non-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The

Notes to financial statements (unaudited) Wells Fargo C&B Large Cap Value Portfolio 31

Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund, if any, is included in income from affiliated securities on the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on the ex-dividend date. Dividend income is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $354,702,026 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	87,654,641
Gross unrealized losses		(18,089,492	)
Net unrealized gains	$	69,565,149

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

At November 30, 2018, the Portfolio did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES AND OTHER EXPENSES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible for day-to-day portfolio management of the Portfolios. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.65% and declining to 0.475% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.65% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. Cooke & Bieler, L.P., which is not an affiliate of Funds Management, is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.38% and declining to 0.30% as the average daily net assets of the Portfolio increase.

Funds Management has voluntarily waived and/or reimbursed advisory fees to the extent necessary to maintain the net operating expense ratio of the Portfolio.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $133,003,984 and $97,221,906, respectively.

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use

Notes to financial statements (unaudited) Wells Fargo C&B Large Cap Value Portfolio 33

bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. CONCENTRATION RISK

Concentration risks result from exposure to a limited number of sectors. A portfolio that invests a substantial portion of its assets in a sector may be more affected by changes in that sector than would be a portfolio whose investments are not heavily weighted in any sector.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo Emerging Growth Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the third quarter of 2018.

Dear Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo Emerging Growth Fund for thesix-month period that ended November 30, 2018. During the reporting period, the U.S. generated encouraging economic and business data that was offset by less positive and more inconsistent data from international markets. Investment returns were restrained in comparison with recent periods as geopolitical tensions and uncertainty tended to distract investors from more favorable underlying trends.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ gained 3.02% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 8.37%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 9.89%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ declined 0.30% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.67%. The Bloomberg Barclays Municipal Bond Index⁶ gained 0.42%. The ICE BofAML U.S. High Yield Index⁷ was up 0.19%.

Global trade tensions prompted investor concerns.

Global trade tensions escalated during the third quarter of 2018. The U.S. government’s decision during the second quarter to impose tariffs on a wide range of products manufactured overseas drew retaliatory responses from foreign governments, which punished U.S. commodity producers and product manufacturers. Investors were left to wonder about next steps in what appeared to be an escalating divergence in global economic policies and growth prospects.

Inflation trended higher. TheCPI-U⁸ added 0.1% in September after an increase of 0.2% in both July and August. On a year-over-year basis, theall-items index rose 2.3% for the 12 months that ended September 30, 2018, after a seasonal adjustment. The rate of increase was slower than that recorded during the first half of 2018. The index for all items less food and energy rose 2.2% for the same12-month period.

¹  The S&P 500 Index consists of 500 stocks chosen for market size, liquidity, and industry group representation. It is a market-value-weighted index with each stock’s weight in the index proportionate to its market value. You cannot invest directly in an index.

Source: MSCI. MSCI makes no express or implied warranties or representations and shall have no liability whatsoever with respect to any MSCI data contained herein. The MSCI data may not be further redistributed or used as a basis for other indices or any securities or financial products. This report is not approved, reviewed, or produced by MSCI. You cannot invest directly in an index.

³  The MSCI Emerging Markets (EM) Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure large- andmid-cap equity market performance of emerging markets. The MSCI EM Index (Net) consists of the following 24 emerging market country indices: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, the Philippines, Poland, Qatar, Russia, South Africa, Taiwan, Thailand, Turkey, and the United Arab Emirates.

Letter to shareholders (unaudited) Wells Fargo Emerging Growth Fund 3

U.S. stocks gained following positive economic data while international stocks and bonds declined.

During the summer months, the U.S. economy strengthened. Revised second-quarter gross domestic product (GDP) data released in August showed the U.S. economy growing at a 4.2% rate. The unemployment rate in the U.S. was 3.7% by the end of September, according to the U.S. Department of Labor. Wages showed more consistent growth, and consumer confidence remained strong. Several U.S. equity market indices reached records during August, with the S&P 500 Index gaining 7.20% for the three-month period that ended September 30, 2018. In contrast, the MSCI ACWI ex USA Index (Net) gained 0.71% while the MSCI EM Index (Net) declined 1.09% during the same three-month period.

In June, the Federal Reserve increased the target range for the federal funds rate to range from 1.75% to 2.00%. It raised the range again in September to range from 2.00% to 2.25%. Long-term interest rates in the U.S. remained at higher levels relative to the prior 10 years. Rates on10-year and30-year Treasury bonds—2.46% and 2.81%, respectively, on January 1, 2018—were 3.01% and 3.30%, respectively, on November 30, 2018. Investor concerns about an inverted yield curve reemerged, only to be replaced by concerns about the potentially negative influence of higher interest rates on economic activity.

November saw improvement in many equity markets.

As interest rates and bond yields gained during October, stock markets struggled. For the month, the S&P 500 Index fell 6.84%, the MSCI ACWI ex USA Index (Net) dropped 8.13%, and the MSCI EM Index (Net) lost 8.71%. The Bureau of Economic Analysis released its first estimate of third-quarter GDP, which, at an annualized 3.5% rate, indicated growth may be slowing compared with the second quarter. Readings on consumer sentiment and business spending were mixed. Markets rebounded somewhat in November as the S&P 500 Index gained 2.04%, the MSCI ACWI ex USA Index (Net) added 0.95%, and the MSCI EM Index (Net) was up 4.12% as the uncertainty leading up to midterm elections in the U.S. was resolved and progress seemed to be possible on several international trade issues.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began. In early August, the Bank of England’s Monetary Policy Committee increased its key interest rate to 0.75%. The European Central Bank and the Bank of Japan maintained low interest rates and accommodative monetary policies. Amid rising trade uncertainty, the People’s Bank of China cut reserve requirement ratios and accelerated infrastructure spending and tax cuts for business enterprises and individuals. Nevertheless, a strengthening U.S. dollar and the trade tensions remained headwinds for investors overseas.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the redemption of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance shown without sales charges would be lower if sales charges were reflected. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Current month-end performance is available on the Fund’s website, wellsfargofunds.com.

Index returns do not include transaction costs associated with buying and selling securities, any mutual fund fees or expenses, or any taxes. It is not possible to invest directly in an index.

For Class A shares, the maximum front-end sales charge is 5.75%. For Class C shares, the maximum contingent deferred sales charge is 1.00%. Performance including a contingent deferred sales charge assumes the sales charge for the corresponding time period. Class R6, Administrator Class, and Institutional Class shares are sold without a front-end sales charge or contingent deferred sales charge.

Stock values fluctuate in response to the activities of individual companies and general market and economic conditions. Smaller-company stocks tend to be more volatile and less liquid than those of larger companies. Certain investment strategies tend to increase the total risk of an investment (relative to the broader market). The Fund is exposed to foreign investment risk. Consult the Fund’s prospectus for additional information on these and other risks.

¹  The Fund is a gateway feeder fund that invests substantially all of its assets in a single affiliated master portfolio of the Wells Fargo Master Trust with a substantially identical investment objective and substantially similar investment strategies. References to the investment activities of the Fund are intended to refer to the investment activities of the affiliated master portfolio in which it invests.

²  Historical performance shown for Class R6 shares prior to their inception reflects the performance of Institutional Class shares, and includes the higher expenses applicable to Institutional Class shares. If these expenses had not been included, returns for Class R6 shares would be higher.

³  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

⁴  The manager has contractually committed through September 30, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s Total Annual Fund Operating Expenses After Fee Waivers at the amounts shown. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any) from funds in which the affiliated master portfolio invests, and extraordinary expenses are excluded from the expense cap. Net expenses from the affiliated master portfolio are included in the expense cap. Without this cap, the Fund’s returns would have been lower. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁵  The Russell 2000^® Growth Index measures the performance of those Russell 2000 companies with higher price/book ratios and higher forecasted growth values. You cannot invest directly in an index.

⁶  The ten largest holdings, excluding cash, cash equivalents and any money market funds, are calculated based on the value of the securities of the affiliated master portfolio allocable to the Fund divided by the total net assets of the Fund. Holdings are subject to change and may have changed since the date specified.

⁷  Amounts represent the sector distribution of the affiliated master portfolio which are calculated based on the total long-term investments of the affiliated master portfolio. These amounts are subject to change and may have changed since the date specified.

8 Wells Fargo Emerging Growth Fund Fund expenses (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution (12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period from June 1, 2018 to November 30, 2018.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

² Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect the one-half-year period).

18 Wells Fargo Emerging Growth Fund Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Emerging Growth Fund (the “Fund”) which is a diversified series of the Trust.

The Fund is a feeder fund in a master-feeder structure that invests substantially all of its assets in a single master portfolio with a substantially identical investment objective and substantially similar investment strategies. The Fund seeks to achieve its investment objective by investing all investable assets in a separate diversified portfolio (the “affiliated Master Portfolio”) of Wells Fargo Master Trust, a registered open-end management investment company. The affiliated Master Portfolio directly acquires portfolio securities and the Fund acquires an indirect interest in those securities. The Fund accounts for its investment in the affiliated Master Portfolio as a partnership investment and records on a daily basis its share of the affiliated Master Portfolio’s income, expense and realized and unrealized gains and losses. The financial statements of the affiliated Master Portfolio for the six months ended November 30, 2018 are included in this report and should be read in conjunction with the Fund’s financial statements. As of November 30, 2018, the Fund owned 89% of Wells Fargo Emerging Growth Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation time under unusual or unexpected circumstances.

Investments in the affiliated Master Portfolio are valued daily based on the Fund’s proportionate share of the affiliated Master Portfolio’s net assets, which are also valued daily. Securities held in the affiliated Master Portfolio are valued as discussed in the Notes to Financial Statements of the affiliated Master Portfolio, which are included elsewhere in this report.

Investment transactions, income and expenses

Investments in the affiliated Master Portfolio are recorded on a trade basis.

The Fund records daily its proportionate share of the affiliated Master Portfolio’s interest and dividend income, expenses and realized and unrealized gains or losses. The Fund also accrues its own expenses.

Distributions to shareholders

Distributions to shareholders from net investment income and any net realized gains are recorded on the ex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Notes to financial statements (unaudited) Wells Fargo Emerging Growth Fund 19

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $549,635,880 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	238,726,004
Gross unrealized losses		0
Net unrealized gains	$	238,726,004

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

At November 30, 2018, the affiliated Master Portfolio was measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The investment objective and the value of the affiliate Master Portfolio was as follows:

Affiliated Master Portfolio	Investment objective	Value of affiliated Master Portfolio
Wells Fargo Emerging Growth Portfolio	Seeks long-term capital appreciation		$788,361,884

The affiliated Master Portfolio does not have a redemption period notice, can be redeemed daily and does not have any unfunded commitments.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Wells Fargo Funds Management, LLC (“Funds Management”), an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As long as the Fund continues to invest substantially all of its assets in a single affiliated Master Portfolio, the Fund pays Funds Management an investment management fee only for fund-level administrative services at an annual rate starting at 0.05% and declining to 0.03% as the average daily net assets of the Fund increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.05% of the Fund’s average daily net assets.

Funds Management also serves as the adviser to the affiliated Master Portfolio and is entitled to receive a fee from the affiliated Master Portfolio for those services.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent, sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C		0.21	%
Class R6		0.03
Administrator Class, Institutional Class		0.13

20 Wells Fargo Emerging Growth Fund Notes to financial statements (unaudited)

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Net expenses from the affiliated Master Portfolio are included in the expense cap. Funds Management has committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap each Fund’s expenses at 1.28% for Class A shares, 2.03% for Class C shares, 0.85% for Class R6 shares, 1.20% for Class Administrator Class shares, and 0.90% for Institutional Class shares. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.Prior to August 1, 2018, the Fund’s expenses were capped at 1.35% for Class A shares and 2.10% for Class C shares.

Distribution fee

The Trust has adopted a distribution plan for Class C shares of the Fund pursuant to Rule 12b-1 under the 1940 Act. A distribution fee is charged to Class C shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares.

In addition, Funds Distributor is entitled to receive the front-end sales charge from the purchase of Class A shares and a contingent deferred sales charge on the redemption of certain Class A shares. Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. For the six months ended November 30, 2018, Funds Distributor received $1,852 from the sale of Class A shares. No contingent deferred sales charges were incurred by Class A and Class C shares for the six months ended November 30, 2018.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Class C, and Administrator Class of the Fund are charged a fee at an annual rate of 0.25% of the average daily net assets of each respective class.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

5. INVESTMENT PORTFOLIO TRANSACTIONS

The Fund seeks to achieve its investment objective by investing substantially all of its investable assets in a single affiliated Master Portfolio. Purchases and sales have been calculated by multiplying the Fund’s ownership percentage of the affiliated Master Portfolio by the affiliated Master Portfolio’s purchases and sales. Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $325,877,495 and $322,249,252, respectively.

6. BANK BORROWINGS

The Trust (excluding the money market funds), Wells Fargo Master Trust and Wells Fargo Variable Trust are parties to a $280,000,000 revolving credit agreement whereby the Fund is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Fund based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Fund under the agreement.

7. DISTRIBUTIONS TO SHAREHOLDERS

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders. The amounts of distributions to shareholders for the year ended May 31, 2018 were as follows:

	Net realized gains
Class A		$16,172,743
Class C		446,164
Administrator Class		5,883,416
Institutional Class		62,422,402

Notes to financial statements (unaudited) Wells Fargo Emerging Growth Fund 21

8. CONCENTRATION RISK

Concentration risk result from exposure to a limited number of sectors. Through its investment in the affiliated Master Portfolio which may invest a substantial portion of its assets in any sector, the Fund may in turn be more affected by changes in that sector than a fund whose investments are not heavily weighted in any sector.

9. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

10. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

11. SUBSEQUENT DISTRIBUTION

On December 12, 2018, the Fund declared distributions from short-term capital gains and long-term capital gains to shareholders of record on December 11, 2018. The per share amounts payable on December 13, 2018 were as follows:

	Short-term capital gains		Long-term capital gains
Class A		$0.33298		$2.84278
Class C		0. 33298		2.84278
Class R6		0. 33298		2.84278
Administrator Class		0. 33298		2.84278
Institutional Class		0. 33298		2.84278

These distributions are not reflected in the accompanying financial statements.

32 Wells Fargo Emerging Growth Portfolio Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Emerging Growth Portfolio (“Emerging Growth Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Investments in registered open-end investment companies are valued at net asset value. Interests in non-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The

Notes to financial statements (unaudited) Wells Fargo Emerging Growth Portfolio 33

Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund is included in securities lending income from affiliates (net of fees and rebates) on the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on the ex-dividend date.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $639,205,435 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	295,531,370
Gross unrealized losses		(29,460,441	)
Net unrealized gains	$	266,070,929

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

At November 30, 2018, the Portfolio did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible for day-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.80% and declining to 0.68% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.79% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. WellsCap is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.55% and declining to 0.40% as the average daily net assets of the Portfolio increase.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $364,240,421 and $360,185,055, respectively.

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

Notes to financial statements (unaudited) Wells Fargo Emerging Growth Portfolio 35

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. CONCENTRATION RISK

Concentration risks result from exposure to a limited number of sectors. A portfolios that invest a substantial portion of its assets in a sector may be more affected by changes in that sector than would be a portfolio whose investments are not heavily weighted in any sector.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo Index Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the third quarter of 2018.

Dear Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo Index Fund for thesix-month period that ended November 30, 2018. During the reporting period, the U.S. generated encouraging economic and business data that was offset by less positive and more inconsistent data from international markets. Investment returns were restrained in comparison with recent periods as geopolitical tensions and uncertainty tended to distract investors from more favorable underlying trends.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ gained 3.02% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 8.37%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 9.89%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ declined 0.30% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.67%. The Bloomberg Barclays Municipal Bond Index⁶ gained 0.42%. The ICE BofAML U.S. High Yield Index⁷ was up 0.19%.

Global trade tensions prompted investor concerns.

Global trade tensions escalated during the third quarter of 2018. The U.S. government’s decision during the second quarter to impose tariffs on a wide range of products manufactured overseas drew retaliatory responses from foreign governments, which punished U.S. commodity producers and product manufacturers. Investors were left to wonder about next steps in what appeared to be an escalating divergence in global economic policies and growth prospects.

Inflation trended higher. TheCPI-U⁸ added 0.1% in September after an increase of 0.2% in both July and August. On a year-over-year basis, theall-items index rose 2.3% for the 12 months that ended September 30, 2018, after a seasonal adjustment. The rate of increase was slower than that recorded during the first half of 2018. The index for all items less food and energy rose 2.2% for the same12-month period.

¹  The S&P 500 Index consists of 500 stocks chosen for market size, liquidity, and industry group representation. It is a market-value-weighted index with each stock’s weight in the index proportionate to its market value. You cannot invest directly in an index.

²  The Morgan Stanley Capital International (MSCI) All Country World Index (ACWI) ex USA Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure the equity market performance of developed markets, excluding the U.S. and Canada. Source: MSCI. MSCI makes no express or implied warranties or representations and shall have no liability whatsoever with respect to any MSCI data contained herein. The MSCI data may not be further redistributed or used as a basis for other indices or any securities or financial products. This report is not approved, reviewed, or produced by MSCI. You cannot invest directly in an index.

³  The MSCI Emerging Markets (EM) Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure large- andmid-cap equity market performance of emerging markets. The MSCI EM Index (Net) consists of the following 24 emerging market country indices: Brazil, Chile, China, Colombia, the Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, the Philippines, Poland, Qatar, Russia, South Africa, Taiwan, Thailand, Turkey, and the United Arab Emirates. You cannot invest directly in an index.

⁴  The Bloomberg Barclays U.S. Aggregate Bond Index is a broad-based benchmark that measures the investment-grade, U.S.-dollar-denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable-rate mortgage pass-throughs), asset-backed securities, and commercial mortgage-backed securities. You cannot invest directly in an index.

⁵  The Bloomberg Barclays Global Aggregateex-USD Index is an unmanaged index that provides a broad-based measure of the global investment-grade fixed-income markets excluding the U.S.-dollar-denominated debt market. You cannot invest directly in an index.

The index tracks the performance of high-yield securities traded in the U.S. bond market. You cannot invest directly in an index. Copyright 2018. ICE Data Indices, LLC. All rights reserved.

⁸  The Consumer Price Index for All Urban Consumers(CPI-U) measures the changes in the price of a basket of goods and services purchased by urban consumers. The urban consumer population is deemed by many as a better representative measure of the general public because close to 90% of the country’s population lives in highly populated areas.

Letter to shareholders (unaudited) Wells Fargo Index Fund 3

U.S. stocks gained following positive economic data while international stocks and bonds declined.

During the summer months, the U.S. economy strengthened. Revised second-quarter gross domestic product (GDP) data released in August showed the U.S. economy growing at a 4.2% rate. The unemployment rate in the U.S. was 3.7% by the end of September, according to the U.S. Department of Labor. Wages showed more consistent growth, and consumer confidence remained strong. Several U.S. equity market indices reached records during August, with the S&P 500 Index gaining 7.20% for the three-month period that ended September 30, 2018. In contrast, the MSCI ACWI ex USA Index (Net) gained 0.71% while the MSCI EM Index (Net) declined 1.09% during the same three-month period.

In June, the Federal Reserve increased the target range for the federal funds rate to range from 1.75% to 2.00%. It raised the range again in September to range from 2.00% to 2.25%. Long-term interest rates in the U.S. remained at higher levels relative to the prior 10 years. Rates on10-year and30-year Treasury bonds—2.46% and 2.81%, respectively, on January 1, 2018—were 3.01% and 3.30%, respectively, on November 30, 2018. Investor concerns about an inverted yield curve reemerged, only to be replaced by concerns about the potentially negative influence of higher interest rates on economic activity.

November saw improvement in many equity markets.

As interest rates and bond yields gained during October, stock markets struggled. For the month, the S&P 500 Index fell 6.84%, the MSCI ACWI ex USA Index (Net) dropped 8.13%, and the MSCI EM Index (Net) lost 8.71%. The Bureau of Economic Analysis released its first estimate of third-quarter GDP, which, at an annualized 3.5% rate, indicated growth may be slowing compared with the second quarter. Readings on consumer sentiment and business spending were mixed. Markets rebounded somewhat in November as the S&P 500 Index gained 2.04%, the MSCI ACWI ex USA Index (Net) added 0.95%, and the MSCI EM Index (Net) was up 4.12% as the uncertainty leading up to midterm elections in the U.S. was resolved and progress seemed to be possible on several international trade issues.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began. In early August, the Bank of England’s Monetary Policy Committee increased its key interest rate to 0.75%. The European Central Bank and the Bank of Japan maintained low interest rates and accommodative monetary policies. Amid rising trade uncertainty, the People’s Bank of China cut reserve requirement ratios and accelerated infrastructure spending and tax cuts for business enterprises and individuals. Nevertheless, a strengthening U.S. dollar and the trade tensions remained headwinds for investors overseas.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the redemption of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance shown without sales charges would be lower if sales charges were reflected. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Currentmonth-end performance is available on the Fund’s website,wellsfargofunds.com.

Index returns do not include transaction costs associated with buying and selling securities, any mutual fund fees or expenses, or any taxes. It is not possible to invest directly in an index.

For Class A shares, the maximumfront-end sales charge is 5.75%. For Class C shares, the maximum contingent deferred sales charge is 1.00%. Performance including a contingent deferred sales charge assumes the sales charge for the corresponding time period. Administrator Class shares are sold without afront-end sales charge or contingent deferred sales charge.

Stock values fluctuate in response to the activities of individual companies and general market and economic conditions. The use of derivatives may reduce returns and/or increase volatility. Consult the Fund’s prospectus for additional information on these and other risks.

¹  The Fund is a gateway feeder fund that invests substantially all of its assets in a single affiliated master portfolio of the Wells Fargo Master Trust with a substantially identical investment objective and substantially similar investment strategies. References to the investment activities of the Fund are intended to refer to the investment activities of the affiliated master portfolio in which it invests.

²  Historical performance shown for all classes of the Fund prior to July 19, 2010, is based on the performance of the Fund’s predecessor, Evergreen Equity Index Fund.

³  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

⁴  The manager has contractually committed through September 30, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s Total Annual Fund Operating Expenses After Fee Waivers at the amounts shown. After this time, the caps may be increased or the commitment to maintain the caps may be terminated only with the approval of the Board of Trustees. Brokerage commissions, stamp duty fees, interest, taxes, acquired money market fund fees and expenses (if any) from funds in which the affiliated master portfolio invests, and extraordinary expenses are excluded from the expense cap. Net expenses from the affiliated master portfolio are included in the expense cap. Without this cap, the Fund’s returns would have been lower. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁵  The S&P 500 Index consists of 500 stocks chosen for market size, liquidity, and industry group representation. It is a market-value-weighted index with each stock’s weight in the index proportionate to its market value. You cannot invest directly in an index.

⁶  The ten largest holdings, excluding cash, cash equivalents and any money market funds, are calculated based on the value of the securities of the affiliated master portfolio allocable to the Fund divided by the total net assets of the Fund. Holdings are subject to change and may have changed since the date specified.

⁷  Amounts represent the sector distribution of the affiliated master portfolio which are calculated based on the total long-term investments of the affiliated master portfolio. These amounts are subject to change and may have changed since the date specified.

8 Wells Fargo Index Fund Fund expenses (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution(12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from June 1, 2018 to November 30, 2018.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

16 Wells Fargo Index Fund Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Index Fund (the “Fund”) which is a diversified series of the Trust.

The Fund is a feeder fund in a master-feeder structure that invests substantially all of its assets in a single master portfolio with a substantially identical investment objective and substantially similar investment strategies. The Fund seeks to achieve its investment objective by investing all investable assets in a separate diversified portfolio (the “affiliated Master Portfolio”) of Wells Fargo Master Trust, a registeredopen-end management investment company. The affiliated Master Portfolio directly acquires portfolio securities and the Fund acquires an indirect interest in those securities. The Fund accounts for its investment in the affiliated Master Portfolio as a partnership investment and records on a daily basis its share of the affiliated Master Portfolio’s income, expense and realized and unrealized gains and losses. The financial statements of the affiliated Master Portfolio for the six months ended November 30, 2018 are included in this report and should be read in conjunction with the Fund’s financial statements. As of November 30, 2018, the Fund owned 97% of Wells Fargo Index Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation time under unusual or unexpected circumstances.

Investments in the affiliated Master Portfolio are valued daily based on the Fund’s proportionate share of the affiliated Master Portfolio’s net assets, which are also valued daily. Securities held in the affiliated Master Portfolio are valued as discussed in the Notes to Financial Statements of the affiliated Master Portfolio, which are included elsewhere in this report.

Investment transactions, income and expenses

Investments in the affiliated Master Portfolio are recorded on a trade basis.

The Fund records daily its proportionate share of the affiliated Master Portfolio’s interest and dividend income, expenses and realized and unrealized gains or losses. The Fund also accrues its own expenses.

Distributions to shareholders

Distributions to shareholders from net investment income and any net realized gains are recorded on theex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Notes to financial statements (unaudited) Wells Fargo Index Fund 17

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $356,664,227 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	1,134,338,583
Gross unrealized losses		0
Net unrealized gains	$	1,134,338,583

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

At November 30, 2018, the affiliated Master Portfolio was measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The investment objective and the value of the affiliate Master Portfolio was as follows:

Affiliated Master Portfolio	Investment objective	Value of affiliated Master Portfolio
Wells Fargo Index Portfolio	Seeks to replicate the total return of the S&P 500 Index, before fees and expenses		$1,491,002,810

The affiliated Master Portfolio does not have a redemption period notice, can be redeemed daily and does not have any

unfunded commitments.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Wells Fargo Funds Management, LLC (“Funds Management”), an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As long as the Fund continues to invest substantially all of its assets in a single affiliated Master Portfolio, the Fund pays Funds Management an investment management fee only for fund-level administrative services at an annual rate starting at 0.05% and declining to 0.03% as the average daily net assets of the Fund increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.05% of the Fund’s average daily net assets.

Funds Management also serves as the adviser to the affiliated Master Portfolio and is entitled to receive a fee from the affiliated Master Portfolio for those services.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C		0.21	%
Administrator Class		0.13

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its

18 Wells Fargo Index Fund Notes to financial statements (unaudited)

expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Net expenses from the affiliated Master Portfolio are included in the expense cap. Funds Management has committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap each Fund’s expenses at 0.45% for Class A shares, 1.20% for Class C shares, and 0.25% for Administrator Class shares. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Distribution fee

The Trust has adopted a distribution plan for Class C shares of the Fund pursuant to Rule12b-1 under the 1940 Act. A distribution fee is charged to Class C shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares.

In addition, Funds Distributor is entitled to receive thefront-end sales charge from the purchase of Class A shares and a contingent deferred sales charge on the redemption of certain Class A shares. Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. For the six months ended November 30, 2018, Funds Distributor received $6,085 from the sale of Class A shares and $12 in contingent deferred sales charges from redemptions of Class C shares. No contingent deferred sales charges were incurred by Class A shares for the six months ended November 30, 2018.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A and Class C of the Fund are charged a fee at an annual rate of 0.25% of the average daily net assets of each respective class. Administrator Class is charged a fee at an annual rate of 0.10% of its average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

5. INVESTMENT PORTFOLIO TRANSACTIONS

The Fund seeks to achieve its investment objective by investing substantially all of its investable assets in a single affiliated Master Portfolio. Purchases and sales have been calculated by multiplying the Fund’s ownership percentage of the affiliated Master Portfolio by the affiliated Master Portfolio’s purchases and sales. Purchases and sales of investments, excluding short-term securities, for the six months ended November 30, 2018 were $35,698,731 and $176,960,427, respectively.

The Trust (excluding the money market funds), Wells Fargo Master Trust and Wells Fargo Variable Trust are parties to a $280,000,000 revolving credit agreement whereby the Fund is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Fund based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Fund under the agreement.

7. DISTRIBUTIONS TO SHAREHOLDERS

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders. The amounts of distributions to shareholders for the year ended May 31, 2018 were as follows:

	Net investment income		Net realized gains
Class A		$11,646,335		$111,399,336

Administrator Class		18,709,88		170,036,456

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

40 Wells Fargo Index Portfolio Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Index Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities and futures contracts that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Debt securities are valued at the evaluated bid price provided by an independent pricing service service (e.g. taking into account various factors, including yields, maturities, or credit ratings) or, if a reliable price is not available, the quoted bid price from an independent broker-dealer.

Investments in registeredopen-end investment companies are valued at net asset value. Interests innon-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”).The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management

Notes to financial statements (unaudited) Wells Fargo Index Portfolio 41

receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund, if any, is included in income from affiliated securities on the Statement of Operations.

Futures contracts

The Portfolio is subject to equity price risk in the normal course of pursuing its investment objectives. Futures contracts are agreements between the Portfolio and a counterparty to buy or sell a specific amount of a commodity, financial instrument or currency at specified price and on a specified date. The Portfolio may buy and sell futures contracts in order to gain exposure to, or protect against, changes in security values. The primary risks associated with the use of futures contracts are the imperfect correlation between changes in market values of securities held by the Portfolio and the prices of futures contracts, and the possibility of an illiquid market. Futures contracts are generally entered into on a regulated futures exchange and cleared through a clearinghouse associated with the exchange. With futures contracts, there is minimal counterparty risk to the Portfolio since futures contracts are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures contracts against default.

Upon entering into a futures contracts, the Portfolio is required to deposit either cash or securities (initial margin) with the broker in an amount equal to a certain percentage of the contract value. Subsequent payments (variation margin) are paid to or from the broker each day equal to the daily changes in the contract value. Such payments are recorded as unrealized gains or losses and, if any, shown as variation margin receivable (payable) in the Statement of Assets and Liabilities. Should the Portfolio fail to make requested variation margin payments, the broker can gain access to the initial margin to satisfy the Portfolio’s payment obligations. When the contracts are closed, a realized gain or loss is recorded in the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on theex-dividend date. Dividend income from foreign securities is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily.To the extent debt obligations are placed onnon-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed fromnon-accrual status.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $544,019,950 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	1,007,430,653
Gross unrealized losses		(18,020,281	)
Net unrealized gains	$	989,410,372

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

For futures contracts, the current day’s variation margin is reported on the Statement of Assets and Liabilities. All other assets and liabilities are reported at their market value at measurement date.

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible forday-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.10% and declining to 0.05% as the average daily net assets of the Portfolio increase. For six month ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.09% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. WellsCap is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.05% and declining to 0.02% as the average daily net assets of the Portfolio increase.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $36,682,684 and $181,837,933, respectively.

6. DERIVATIVE TRANSACTIONS

During the six months ended November 30, 2018, the Portfolio entered into futures contracts to gain market exposure. The Portfolio had an average notional amount of $38,705,971 in long futures contracts during the six months ended November 30, 2018.

The fair value, realized gains or losses and change in unrealized gains or losses, if any, on derivative instruments are reflected in the corresponding financial statement captions.

7. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo International Value Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the third quarter of 2018.

Dear Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo International Value Fund for thesix-month period that ended November 30, 2018. During the reporting period, the U.S. generated encouraging economic and business data that was offset by less positive and more inconsistent data from international markets. Investment returns were restrained in comparison with recent periods as geopolitical tensions and uncertainty tended to distract investors from more favorable underlying trends.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ gained 3.02% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 8.37%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 9.89%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ declined 0.30% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.67%. The Bloomberg Barclays Municipal Bond Index⁶ gained 0.42%. The ICE BofAML U.S. High Yield Index⁷ was up 0.19%.

Global trade tensions prompted investor concerns.

Global trade tensions escalated during the third quarter of 2018. The U.S. government’s decision during the second quarter to impose tariffs on a wide range of products manufactured overseas drew retaliatory responses from foreign governments, which punished U.S. commodity producers and product manufacturers. Investors were left to wonder about next steps in what appeared to be an escalating divergence in global economic policies and growth prospects.

Inflation trended higher. TheCPI-U⁸ added 0.1% in September after an increase of 0.2% in both July and August. On a year-over-year basis, theall-items index rose 2.3% for the 12 months that ended September 30, 2018, after a seasonal adjustment. The rate of increase was slower than that recorded during the first half of 2018. The index for all items less food and energy rose 2.2% for the same12-month period.

¹  The S&P 500 Index consists of 500 stocks chosen for market size, liquidity, and industry group representation. It is a market-value-weighted index with each stock’s weight in the index proportionate to its market value. You cannot invest directly in an index.

²  The Morgan Stanley Capital International (MSCI) All Country World Index (ACWI) ex USA Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure the equity market performance of developed markets, excluding the U.S. and Canada. Source: MSCI. MSCI makes no express or implied warranties or representations and shall have no liability whatsoever with respect to any MSCI data contained herein. The MSCI data may not be further redistributed or used as a basis for other indices or any securities or financial products. This report is not approved, reviewed, or produced by MSCI. You cannot invest directly in an index.

³  The MSCI Emerging Markets (EM) Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure large- andmid-cap equity market performance of emerging markets. The MSCI EM Index (Net) consists of the following 24 emerging market country indices: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, the Philippines, Poland, Qatar, Russia, South Africa, Taiwan, Thailand, Turkey, and the United Arab Emirates. You cannot invest directly in an index.

⁴  The Bloomberg Barclays U.S. Aggregate Bond Index is a broad-based benchmark that measures the investment-grade, U.S.-dollar-denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable-rate mortgage pass-throughs), asset-backed securities, and commercial mortgage-backed securities. You cannot invest directly in an index.

⁵  The Bloomberg Barclays Global Aggregateex-USD Index is an unmanaged index that provides a broad-based measure of the global investment-grade fixed-income markets excluding the U.S.-dollar-denominated debt market. You cannot invest directly in an index.

⁶  The Bloomberg Barclays Municipal Bond Index is an unmanaged index composed of long-termtax-exempt bonds with a minimum credit rating of Baa. You cannot invest directly in an index.

The index tracks the performance of high-yield securities traded in the U.S. bond market. You cannot invest directly in an index. Copyright 2018. ICE Data Indices, LLC. All rights reserved.

⁸  The Consumer Price Index for All Urban Consumers(CPI-U) measures the changes in the price of a basket of goods and services purchased by urban consumers. The urban consumer population is deemed by many as a better representative measure of the general public because close to 90% of the country’s population lives in highly populated areas.

Letter to shareholders (unaudited) Wells Fargo International Value Fund 3

U.S. stocks gained following positive economic data while international stocks and bonds declined.

During the summer months, the U.S. economy strengthened. Revised second-quarter gross domestic product (GDP) data released in August showed the U.S. economy growing at a 4.2% rate. The unemployment rate in the U.S. was 3.7% by the end of September, according to the U.S. Department of Labor. Wages showed more consistent growth, and consumer confidence remained strong. Several U.S. equity market indices reached records during August, with the S&P 500 Index gaining 7.20% for the three-month period that ended September 30, 2018. In contrast, the MSCI ACWI ex USA Index (Net) gained 0.71% while the MSCI EM Index (Net) declined 1.09% during the same three-month period.

In June, the Federal Reserve increased the target range for the federal funds rate to range from 1.75% to 2.00%. It raised the range again in September to range from 2.00% to 2.25%. Long-term interest rates in the U.S. remained at higher levels relative to the prior 10 years. Rates on10-year and30-year Treasury bonds—2.46% and 2.81%, respectively, on January 1, 2018—were 3.01% and 3.30%, respectively, on November 30, 2018. Investor concerns about an inverted yield curve reemerged, only to be replaced by concerns about the potentially negative influence of higher interest rates on economic activity.

November saw improvement in many equity markets.

As interest rates and bond yields gained during October, stock markets struggled. For the month, the S&P 500 Index fell 6.84%, the MSCI ACWI ex USA Index (Net) dropped 8.13%, and the MSCI EM Index (Net) lost 8.71%. The Bureau of Economic Analysis released its first estimate of third-quarter GDP, which, at an annualized 3.5% rate, indicated growth may be slowing compared with the second quarter. Readings on consumer sentiment and business spending were mixed. Markets rebounded somewhat in November as the S&P 500 Index gained 2.04%, the MSCI ACWI ex USA Index (Net) added 0.95%, and the MSCI EM Index (Net) was up 4.12% as the uncertainty leading up to midterm elections in the U.S. was resolved and progress seemed to be possible on several international trade issues.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began. In early August, the Bank of England’s Monetary Policy Committee increased its key interest rate to 0.75%. The European Central Bank and the Bank of Japan maintained low interest rates and accommodative monetary policies. Amid rising trade uncertainty, the People’s Bank of China cut reserve requirement ratios and accelerated infrastructure spending and tax cuts for business enterprises and individuals. Nevertheless, a strengthening U.S. dollar and the trade tensions remained headwinds for investors overseas.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the redemption of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance shown without sales charges would be lower if sales charges were reflected. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Currentmonth-end performance is available on the Fund’s website, wellsfargofunds.com.

Index returns do not include transaction costs associated with buying and selling securities, any mutual fund fees or expenses, or any taxes. It is not possible to invest directly in an index.

For Class A shares, the maximumfront-end sales charge is 5.75%. For Class C shares, the maximum contingent deferred sales charge is 1.00%. Performance including a contingent deferred sales charge assumes the sales charge for the corresponding time period. Class R6, Administrator Class, and Institutional Class shares are sold without afront-end sales charge or contingent deferred sales charge.

Stock values fluctuate in response to the activities of individual companies and general market and economic conditions. Foreign investments are especially volatile and can rise or fall dramatically due to differences in the political and economic conditions of the host country. These risks are generally intensified in emerging markets. The use of derivatives may reduce returns and/or increase volatility. Certain investment strategies tend to increase the total risk of an investment (relative to the broader market). The Fund is exposed to smaller company securities risk. Consult the Fund’s prospectus for additional information on these and other risks.

¹  The Fund is a gateway feeder fund that invests substantially all of its assets in a single affiliated master portfolio of the Wells Fargo Master Trust with a substantially identical investment objective and substantially similar investment strategies. References to the investment activities of the Fund are intended to refer to the investment activities of the affiliated master portfolio in which it invests.

²  Historical performance shown for the Class R6 shares prior to their inception reflects the performance of the Institutional Class shares, and is not adjusted to reflect Class R6 expenses. If these expenses had been included, returns for Class R6 shares would be higher.

³  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

⁴  The manager has contractually committed through September 30, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s Total Annual Fund Operating Expenses After Fee Waivers at the amounts shown. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Brokerage commissions, stamp duty fees, interest, taxes, acquired money market fund fees and expenses (if any) from funds in which the underlying master portfolio invests, and extraordinary expenses are excluded from the expense cap. Net expenses from the underlying affiliated master portfolio are included in the expense cap. Without this cap, the Fund’s returns would have been lower. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁵  The Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) Value Index (Net) is a free-float-adjusted market capitalization-weighted index that is designed to measure the equity market performance of value securities within developed equity markets, excluding the United States and Canada. The MSCI EAFE Value Index (Net) consists of the following 21 developed markets country indexes: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom.

You cannot invest directly in an index.

⁶  The ten largest holdings, excluding cash, cash equivalents and any money market funds, are calculated based on the value of the securities of the affiliated master portfolio allocable to the Fund divided by the total net assets of the Fund. Holdings are subject to change and may have changed since the date specified.

⁷  Amounts represent the composition of the affiliated master portfolio which are calculated based on the total long-term investments of the affiliated master portfolio. These amounts are subject to change and may have changed since the date specified.

8 Wells Fargo International Value Fund Fund expenses (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution(12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from June 1, 2018 to November 30, 2018.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies.

The Fund is a feeder fund in a master-feeder structure that invests substantially all of its assets in a single master portfolio with a substantially identical investment objective and substantially similar investment strategies. The Fund seeks to achieve its investment objective by investing all investable assets in a separate diversified portfolio (the “affiliated Master Portfolio”) of Wells Fargo Master Trust, a registeredopen-end management investment company. The affiliated Master Portfolio directly acquires portfolio securities and the Fund acquires an indirect interest in those securities. The Fund accounts for its investment in the affiliated Master Portfolio as a partnership investment and records on a daily basis its share of the affiliated Master Portfolio’s income, expense and realized and unrealized gains and losses. The financial statements of the affiliated Master Portfolio for the six months ended November 30, 2018 are included in this report and should be read in conjunction with the Fund’s financial statements. As of November 30, 2018, the Fund owned 77% of Wells Fargo International Value Portfolio.

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation time under unusual or unexpected circumstances.

Investments in the affiliated Master Portfolio are valued daily based on the Fund’s proportionate share of the affiliated Master Portfolio’s net assets, which are also valued daily. Securities held in the affiliated Master Portfolio are valued as discussed in the Notes to Financial Statements of the affiliated Master Portfolio, which are included elsewhere in this report.

Investment transactions, income and expenses

Investments in the affiliated Master Portfolio are recorded on a trade basis.

The Fund records daily its proportionate share of the affiliated Master Portfolio’s interest and dividend income, expenses and realized and unrealized gains or losses. The Fund also accrues its own expenses.

Distributions to shareholders

Distributions to shareholders from net investment income and any net realized gains are recorded on theex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Notes to financial statements (unaudited) Wells Fargo International Value Fund 19

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $887,284,289 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	0
Gross unrealized losses		(26,552,846	)
Net unrealized losses	$	(26,552,846	)

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

At November 30, 2018, the affiliated Master Portfolio was measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The investment objective and the value of the affiliate Master Portfolio was as follows:

Affilated Master Portfolio	Investment objective	Value of affiliated Master Portfolio
Wells Fargo International Value Portfolio	Seeks long-term capital appreciation		$860,731,443

The affiliated Master Portfolio does not have a redemption period notice, can be redeemed daily and does not have any unfunded commitments.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Wells Fargo Funds Management, LLC (“Funds Management”), an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser, and providing fund-level administrative services in connection with the Fund’s operations. As long as the Fund continues to invest substantially all of its assets in a single affiliated Master Portfolio, the Fund pays Funds Management an investment management fee only for fund-level administrative services at an annual rate starting at 0.05% and declining to 0.03% as the average daily net assets of the Fund increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.05% of the Fund’s average daily net assets.

Funds Management also serves as the adviser to the affiliated Master Portfolio and is entitled to receive a fee from the affiliated Master Portfolio for those services.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C		0.21	%
Class R6		0.03
Administrator Class, Institutional Class		0.13

20 Wells Fargo International Value Fund Notes to financial statements (unaudited)

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Net expenses from the affiliated Master Portfolio are included in the expense cap. Funds Management has committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 1.35% for Class A shares, 2.10% for Class C shares, 0.90% for Class R6 shares, 1.25% for Administrator Class shares, and 1.00% for Institutional Class shares. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Distribution fee

The Trust has adopted a Distribution Plan for Class C shares of the Fund pursuant to Rule12b-1 under the 1940 Act. A distribution fee is charged to Class C shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares.

In addition, Funds Distributor is entitled to receive thefront-end sales charge from the purchase of Class A shares and a contingent deferred sales charge on the redemption of certain Class A shares. Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. For the six months ended November 30, 2018, Funds Distributor received $218 from the sale of Class A shares. No contingent deferred sales charges were incurred by Class A and Class C shares for the six months ended November 30, 2018.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Class C, and Administrator Class of each applicable Fund are charged a fee at an annual rate of 0.25% of the average daily net assets of each respective class.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

5. INVESTMENT PORTFOLIO TRANSACTIONS

The Fund seeks to achieve its investment objective by investing substantially all of its investable assets in a single affiliated Master Portfolio. Purchases and sales have been calculated by multiplying the Fund’s ownership percentage of the affiliated Master Portfolio by the affiliated Master Portfolio’s purchases and sales. Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $300,265,180 and $54,850,096, respectively.

6. BANK BORROWINGS

The Trust (excluding the money market funds), Wells Fargo Master Trust and Wells Fargo Variable Trust are parties to a $280,000,000 revolving credit agreement whereby the Fund is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Fund based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Fund under the agreement.

7. DISTRIBUTIONS TO SHAREHOLDERS

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders. The amounts of distributions to shareholders for the year ended May 31, 2018 were as follows:

	Net investment income
Class A	$	53,028
Class C		19,938
Administrator Class		104,265
Institutional Class		22,325,915

Notes to financial statements (unaudited) Wells Fargo International Value Fund 21

8. CONCENTRATION RISK

Concentration risks result from exposure to a limited number of sectors. Through its investment in the affiliated Master Portfolio which may invest a substantial portion of its assets in any sector, the Fund may in turn be more affected by changes in that sector than a fund whose investments are not heavily weighted in any sector.

9. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

10. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

11. SUBSEQUENT DISTRIBUTIONS

On December 27, 2018, the Fund declared distributions from net investment income to shareholders of record on December 26, 2018. The per share amounts payable on December 28, 2018 were as follows:

	Net investment income
Class A		$0.32558
Class C		0.18817
Class R6		0.36845
Administrator Class		0.30162
Institutional Class		0.35227

These distributions are not reflected in the accompanying financial statements.

Notes to financial statements (unaudited) Wells Fargo International Value Portfolio 35

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo International Value Portfolio ( “International Value Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

The values of securities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”).

Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange and therefore may not fully reflect trading or events that occur after the close of the principal exchange in which the foreign securities are traded, but before the close of the New York Stock Exchange. If such trading or events are expected to materially affect the value of such securities, then fair value pricing procedures approved by the Board of Trustees of the Fund are applied. These procedures take into account multiple factors including movements in U.S. securities markets after foreign exchanges close. Foreign securities that are fair valued under these procedures are categorized as Level 2 and the application of these procedures may result in transfers between Level 1 and Level 2. Depending on market activity, such fair valuations may be frequent. Such fair value pricing may result in net asset values that are higher or lower than net asset values based on the last reported sales price or latest quoted bid price. On November 30, 2018, such fair value pricing was used in pricing foreign securities.

Investments in registeredopen-end investment companies are valued at net asset value. Interests innon-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee.The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Foreign currency translation

The accounting records of the Portfolio are maintained in U.S. dollars. The values of other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee. Purchases and sales of securities, and income and expenses are converted at the rate of exchange on the respective dates of such transactions. Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually paid or received. Net unrealized foreign exchange gains and losses arise from changes in the fair value of assets and liabilities other than investments in securities resulting from changes in exchange rates. The changes in net assets arising from changes in exchange rates of securities and the changes in net assets resulting from changes in market prices of securities are not separately presented. Such changes are included in net realized and unrealized gains or losses from investments.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund, if any, is included in income from affiliated securities on the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on the ex-dividend date, except for certain dividends from foreign securities, which are recorded as soon as the custodian verifies the ex-dividend date. Dividend income from foreign securities is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $1,188,628,963 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	86,712,123
Gross unrealized losses		(131,094,009	)
Net unrealized losses	$	(44,381,886	)

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

Notes to financial statements (unaudited) Wells Fargo International Value Portfolio 37

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

4. TRANSACTIONS WITH AFFILIATES AND OTHER EXPENSES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible forday-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.80% and declining to 0.65% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.76% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. LSV Asset Management, which is not an affiliate of Funds Management, is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.35% and declining to 0.30% as the average daily net assets of the of Portfolio increase.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $389,895,973 and $70,938,544, respectively.

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. CONCENTRATION RISK

Concentration risks result from exposure to a limited number of sectors. A portfolio that invests a substantial portion of its assets in a sector may be more affected by changes in that sector than would be a portfolio whose investments are not heavily weighted in any sector.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo Small Company Growth Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the third quarter of 2018.

Dear Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo Small Company Growth Fund for thesix-month period that ended November 30, 2018. During the reporting period, the U.S. generated encouraging economic and business data that was offset by less positive and more inconsistent data from international markets. Investment returns were restrained in comparison with recent periods as geopolitical tensions and uncertainty tended to distract investors from more favorable underlying trends.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ gained 3.02% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 8.37%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 9.89%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ declined 0.30% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.67%. The Bloomberg Barclays Municipal Bond Index⁶ gained 0.42%. The ICE BofAML U.S. High Yield Index⁷ was up 0.19%.

Global trade tensions prompted investor concerns.

Global trade tensions escalated during the third quarter of 2018. The U.S. government’s decision during the second quarter to impose tariffs on a wide range of products manufactured overseas drew retaliatory responses from foreign governments, which punished U.S. commodity producers and product manufacturers. Investors were left to wonder about next steps in what appeared to be an escalating divergence in global economic policies and growth prospects.

Inflation trended higher. TheCPI-U⁸ added 0.1% in September after an increase of 0.2% in both July and August. On a year-over-year basis, theall-items index rose 2.3% for the 12 months that ended September 30, 2018, after a seasonal adjustment. The rate of increase was slower than that recorded during the first half of 2018. The index for all items less food and energy rose 2.2% for the same12-month period.

¹  The S&P 500 Index consists of 500 stocks chosen for market size, liquidity, and industry group representation. It is a market-value-weighted index with each stock’s weight in the index proportionate to its market value. You cannot invest directly in an index.

²  The Morgan Stanley Capital International (MSCI) All Country World Index (ACWI) ex USA Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure the equity market performance of developed markets, excluding the U.S. and Canada. Source: MSCI. MSCI makes no express or implied warranties or representations and shall have no liability whatsoever with respect to any MSCI data contained herein. The MSCI data may not be further redistributed or used as a basis for other indices or any securities or financial products. This report is not approved, reviewed, or produced by MSCI. You cannot invest directly in an index.

³  The MSCI Emerging Markets (EM) Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure large- andmid-cap equity market performance of emerging markets. The MSCI EM Index (Net) consists of the following 24 emerging market country indices: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, the Philippines, Poland, Qatar, Russia, South Africa, Taiwan, Thailand, Turkey, and the United Arab Emirates.

You cannot invest directly in an index.

⁵  The Bloomberg Barclays Global Aggregateex-USD Index is an unmanaged index that provides a broad-based measure of the global investment-grade fixed-income markets excluding the U.S.-dollar-denominated debt market. You cannot invest directly in an index.

Letter to shareholders (unaudited) Wells Fargo Small Company Growth Fund 3

U.S. stocks gained following positive economic data while international stocks and bonds declined.

During the summer months, the U.S. economy strengthened. Revised second-quarter gross domestic product (GDP) data released in August showed the U.S. economy growing at a 4.2% rate. The unemployment rate in the U.S. was 3.7% by the end of September, according to the U.S. Department of Labor. Wages showed more consistent growth, and consumer confidence remained strong. Several U.S. equity market indices reached records during August, with the S&P 500 Index gaining 7.20% for the three-month period that ended September 30, 2018. In contrast, the MSCI ACWI ex USA Index (Net) gained 0.71% while the MSCI EM Index (Net) declined 1.09% during the same three-month period.

In June, the Federal Reserve increased the target range for the federal funds rate to range from 1.75% to 2.00%. It raised the range again in September to range from 2.00% to 2.25%. Long-term interest rates in the U.S. remained at higher levels relative to the prior 10 years. Rates on10-year and30-year Treasury bonds—2.46% and 2.81%, respectively, on January 1, 2018—were 3.01% and 3.30%, respectively, on November 30, 2018. Investor concerns about an inverted yield curve reemerged, only to be replaced by concerns about the potentially negative influence of higher interest rates on economic activity.

November saw improvement in many equity markets.

As interest rates and bond yields gained during October, stock markets struggled. For the month, the S&P 500 Index fell 6.84%, the MSCI ACWI ex USA Index (Net) dropped 8.13%, and the MSCI EM Index (Net) lost 8.71%. The Bureau of Economic Analysis released its first estimate of third-quarter GDP, which, at an annualized 3.5% rate, indicated growth may be slowing compared with the second quarter. Readings on consumer sentiment and business spending were mixed. Markets rebounded somewhat in November as the S&P 500 Index gained 2.04%, the MSCI ACWI ex USA Index (Net) added 0.95%, and the MSCI EM Index (Net) was up 4.12% as the uncertainty leading up to midterm elections in the U.S. was resolved and progress seemed to be possible on several international trade issues.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began. In early August, the Bank of England’s Monetary Policy Committee increased its key interest rate to 0.75%. The European Central Bank and the Bank of Japan maintained low interest rates and accommodative monetary policies. Amid rising trade uncertainty, the People’s Bank of China cut reserve requirement ratios and accelerated infrastructure spending and tax cuts for business enterprises and individuals. Nevertheless, a strengthening U.S. dollar and the trade tensions remained headwinds for investors overseas.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the redemption of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance shown without sales charges would be lower if sales charges were reflected. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Currentmonth-end performance is available on the Fund’s website, wellsfargofunds.com.

Index returns do not include transaction costs associated with buying and selling securities, any mutual fund fees or expenses, or any taxes. It is not possible to invest directly in an index.

For Class A shares, the maximumfront-end sales charge is 5.75%. For Class C shares, the maximum contingent deferred sales charge is 1.00%. Performance including a contingent deferred sales charge assumes the sales charge for the corresponding time period. Class R6, Administrator Class, and Institutional Class shares are sold without afront-end sales charge or contingent deferred sales charge.

Stock values fluctuate in response to the activities of individual companies and general market and economic conditions. Smaller-company stocks tend to be more volatile and less liquid than those of larger companies. Certain investment strategies tend to increase the total risk of an investment (relative to the broader market). The Fund is exposed to foreign investment risk. Consult the Fund’s prospectus for additional information on these and other risks.

¹  The Fund is a gateway feeder fund that invests substantially all of its assets in a single affiliated master portfolio of the Wells Fargo Master Trust with a substantially identical investment objective and substantially similar investment strategies. References to the investment activities of the Fund are intended to refer to the investment activities of the affiliated master portfolio in which it invests.

²  Please see the Fund’s current Statement of Additional Information for further details.

³  Historical performance shown for Class R6 shares prior to their inception reflects the performance of Institutional Class shares, and includes the higher expenses applicable to Institutional Class shares. If these expenses had not been included, returns for Class R6 shares would be higher.

⁴  Reflects the expense ratios as stated in the most recent prospectuses, which include the impact of 0.01% in acquired fund fees and expenses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

⁵  The manager has contractually committed through September 30, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s Total Annual Fund Operating Expenses After Fee Waivers at 1.35% for Class A, 2.10% for Class C, 0.90% for Class R6, 1.20% for Administrator Class, and 0.95% for Institutional Class. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any) from funds in which the affiliated master portfolio invests, and extraordinary expenses are excluded from the expense cap. Net expenses from the affiliated master portfolio are included in the expense cap. Without this cap, the Fund’s returns would have been lower. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁶  The Russell 2000^® Growth Index measures the performance of those Russell 2000 companies with higher price/book ratios and higher forecasted growth values. You cannot invest directly in an index.

⁷  The ten largest holdings, excluding cash, cash equivalents and any money market funds, are calculated based on the value of the securities of the affiliated master portfolio allocable to the Fund divided by the total net assets of the Fund. Holdings are subject to change and may have changed since the date specified.

⁸  Amounts represent the sector distribution of the affiliated master portfolio which are calculated based on the total long-term investments of the affiliated master portfolio. These amounts are subject to change and may have changed since the date specified.

8 Wells Fargo Small Company Growth Fund Fund expenses (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution(12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from June 1, 2018 to November 30, 2018.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

² Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect theone-half-year period).

18 Wells Fargo Small Company Growth Fund Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board(“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Small Company Growth Fund (the “Fund”) which is a diversified series of the Trust.

The Fund is a feeder fund in a master-feeder structure that invests substantially all of its assets in a single master portfolio with a substantially identical investment objective and substantially similar investment strategies. The Fund seeks to achieve its investment objective by investing all investable assets in a separate diversified portfolio (the “affiliated Master Portfolio”) of Wells Fargo Master Trust, a registeredopen-end management investment company. The affiliated Master Portfolio directly acquires portfolio securities and the Fund acquires an indirect interest in those securities. The Fund accounts for its investment in the affiliated Master Portfolio as a partnership investment and records on a daily basis its share of the affiliated Master Portfolio’s income, expense and realized and unrealized gains and losses. The financial statements of the affiliated Master Portfolio for the six months ended November 30, 2018 are included in this report and should be read in conjunction with the Fund’s financial statements. As of November 30, 2018, the Fund owned 98% of Wells Fargo Small Company Growth Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation time under unusual or unexpected circumstances.

Investments in the affiliated Master Portfolio are valued daily based on the Fund’s proportionate share of the affiliated Master Portfolio’s net assets, which are also valued daily. Securities held in the affiliated Master Portfolio are valued as discussed in the Notes to Financial Statements of the affiliated Master Portfolio, which are included elsewhere in this report.

Investment transactions, income and expenses

Investments in the affiliated Master Portfolio are recorded on a trade basis.

The Fund records daily its proportionate share of the affiliated Master Portfolio’s interest and dividend income, expenses and realized and unrealized gains or losses. The Fund also accrues its own expenses.

Distributions to shareholders

Distributions to shareholders from net investment income and any net realized gains are recorded on theex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Notes to financial statements (unaudited) Wells Fargo Small Company Growth Fund 19

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $1,508,464,441 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	431,832,947
Gross unrealized losses		0
Net unrealized gains	$	431,832,947

As of May 31, 2018, the Fund had a qualified late-year ordinary loss of $3,158,480 which was recognized on the first day of the current fiscal year.

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

At November 30, 2018, the affiliated Master Portfolio was measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The investment objective and the value of the affiliate Master Portfolio was as follows:

Affiliated Master Portfolio	Investment objective	Value of affiliated Master Portfolio
Wells Fargo Small Company Growth Portfolio	Seeks long-term capital appreciation		$1,940,297,388

The affiliated Master Portfolio does not have a redemption period notice, can be redeemed daily and does not have any unfunded commitments.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Wells Fargo Funds Management, LLC (“Funds Management”), an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser and providing fund-level administrative services in connection with the Fund’s operations. As long as the Fund continues to invest substantially all of its assets in a single affiliated Master Portfolio, the Fund pays Funds Management an investment management fee only for fund-level administrative services at an annual rate starting at 0.05% and declining to 0.03% as the average daily net assets of the Fund increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.05% of the Fund’s average daily net assets.

Funds Management also serves as the adviser to the affiliated Master Portfolio and is entitled to receive a fee from the affiliated Master Portfolio for those services.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C		0.21	%
Class R6		0.03
Administrator Class, Institutional Class		0.13

20 Wells Fargo Small Company Growth Fund Notes to financial statements (unaudited)

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Net expenses from the affiliated Master Portfolio are included in the expense cap. Funds Management has committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap each Fund’s expenses at 1.35% for Class A shares, 2.10% for Class C shares, 0.90% for Class R6 shares, 1.20% for Administrator Class shares, and 0.95% for Institutional Class shares. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Distribution fee

The Trust has adopted a distribution plan for Class C shares of the Fund pursuant to Rule12b-1 under the 1940 Act. A distribution fee is charged to Class C shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares.

In addition, Funds Distributor is entitled to receive thefront-end sales charge from the purchase of Class A shares and a contingent deferred sales charge on the redemption of certain Class A shares. Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. For the six months ended November 30, 2018, Funds Distributor received $928 from the sale of Class A shares and $11 in contingent deferred sales charges from redemptions of Class C shares. No contingent deferred sales charges were incurred by Class A shares for the six months ended November 30, 2018.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Class C, and Administrator Class of the Fund are charged a fee at an annual rate of 0.25% of the average daily net assets of each respective class.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

5. INVESTMENT PORTFOLIO TRANSACTIONS

The Fund seeks to achieve its investment objective by investing substantially all of its investable assets in a single affiliated Master Portfolio. Purchases and sales have been calculated by multiplying the Fund’s ownership percentage of the affiliated Master Portfolio by the affiliated Master Portfolio’s purchases and sales. Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $648,806,803 and $598,073,839, respectively.

6. BANK BORROWINGS

The Trust (excluding the money market funds), Wells Fargo Master Trust and Wells Fargo Variable Trust are parties to a $280,000,000 revolving credit agreement whereby the Fund is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Fund based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Fund under the agreement.

7. CONCENTRATION RISK

Concentration risks result from exposure to a limited number of sectors. Through its investment in the affiliated Master Portfolio which may invest a substantial portion of its assets in any sector, the Fund may in turn be more affected by changes in that sector than a fund whose investments are not heavily weighted in any sector.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

10. SUBSEQUENT DISTRIBUTIONS

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Small Company Growth Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Investments in registered open-end investment companies are valued at net asset value. Interests in non-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The

Notes to financial statements (unaudited) Wells Fargo Small Company Growth Portfolio 33

Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund is included in securities lending income from affiliates (net of fees and rebates) on the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on the ex-dividend date. Dividend income is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $1,615,904,005 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	570,893,431
Gross unrealized losses		(99,125,721	)
Net unrealized gains	$	471,767,710

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

At November 30, 2018, the Portfolio did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES AND OTHER EXPENSES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible for day-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.80% and declining to 0.68% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.77% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. Peregrine Capital Management, LLC, which is not an affiliate of Funds Management, is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.50% and declining to 0.45% as the average daily net assets of the of Portfolio increase.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $664,274,962 and $612,332,477, respectively.

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under

Notes to financial statements (unaudited) Wells Fargo Small Company Growth Portfolio 35

the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. CONCENTRATION RISK

Concentration risks result from exposure to a limited number of sectors. A portfolio that invest a substantial portion of their assets in a sector may be more affected by changes in that sector than would be a portfolio whose investments are not heavily weighted in any sector.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo Small Company Value Fund Letter to shareholders (unaudited)

Wells Fargo Funds

Global trade tensions escalated during the third quarter of 2018.

Dear Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo Small Company Value Fund for thesix-month period that ended November 30, 2018. During the reporting period, the U.S. generated encouraging economic and business data that was offset by less positive and more inconsistent data from international markets. Investment returns were restrained in comparison with recent periods as geopolitical tensions and uncertainty tended to distract investors from more favorable underlying trends.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ gained 3.02% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 8.37%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 9.89%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ declined 0.30% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.67%. The Bloomberg Barclays Municipal Bond Index⁶ gained 0.42%. The ICE BofAML U.S. High Yield Index⁷ was up 0.19%.

Global trade tensions prompted investor concerns.

Global trade tensions escalated during the third quarter of 2018. The U.S. government’s decision during the second quarter to impose tariffs on a wide range of products manufactured overseas drew retaliatory responses from foreign governments, which punished U.S. commodity producers and product manufacturers. Investors were left to wonder about next steps in what appeared to be an escalating divergence in global economic policies and growth prospects.

Inflation trended higher. TheCPI-U⁸ added 0.1% in September after an increase of 0.2% in both July and August. On a year-over-year basis, theall-items index rose 2.3% for the 12 months that ended September 30, 2018, after a seasonal adjustment. The rate of increase was slower than that recorded during the first half of 2018. The index for all items less food and energy rose 2.2% for the same12-month period.

Letter to shareholders (unaudited) Wells Fargo Small Company Value Fund 3

U.S. stocks gained following positive economic data while international stocks and bonds declined.

During the summer months, the U.S. economy strengthened. Revised second-quarter gross domestic product (GDP) data released in August showed the U.S. economy growing at a 4.2% rate. The unemployment rate in the U.S. was 3.7% by the end of September, according to the U.S. Department of Labor. Wages showed more consistent growth, and consumer confidence remained strong. Several U.S. equity market indices reached records during August, with the S&P 500 Index gaining 7.20% for the three-month period that ended September 30, 2018. In contrast, the MSCI ACWI ex USA Index (Net) gained 0.71% while the MSCI EM Index (Net) declined 1.09% during the same three-month period.

In June, the Federal Reserve increased the target range for the federal funds rate to range from 1.75% to 2.00%. It raised the range again in September to range from 2.00% to 2.25%. Long-term interest rates in the U.S. remained at higher levels relative to the prior 10 years. Rates on10-year and30-year Treasury bonds—2.46% and 2.81%, respectively, on January 1, 2018—were 3.01% and 3.30%, respectively, on November 30, 2018. Investor concerns about an inverted yield curve reemerged, only to be replaced by concerns about the potentially negative influence of higher interest rates on economic activity.

November saw improvement in many equity markets.

As interest rates and bond yields gained during October, stock markets struggled. For the month, the S&P 500 Index fell 6.84%, the MSCI ACWI ex USA Index (Net) dropped 8.13%, and the MSCI EM Index (Net) lost 8.71%. The Bureau of Economic Analysis released its first estimate of third-quarter GDP, which, at an annualized 3.5% rate, indicated growth may be slowing compared with the second quarter. Readings on consumer sentiment and business spending were mixed. Markets rebounded somewhat in November as the S&P 500 Index gained 2.04%, the MSCI ACWI ex USA Index (Net) added 0.95%, and the MSCI EM Index (Net) was up 4.12% as the uncertainty leading up to midterm elections in the U.S. was resolved and progress seemed to be possible on several international trade issues.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began. In early August, the Bank of England’s Monetary Policy Committee increased its key interest rate to 0.75%. The European Central Bank and the Bank of Japan maintained low interest rates and accommodative monetary policies. Amid rising trade uncertainty, the People’s Bank of China cut reserve requirement ratios and accelerated infrastructure spending and tax cuts for business enterprises and individuals. Nevertheless, a strengthening U.S. dollar and the trade tensions remained headwinds for investors overseas.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the redemption of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance shown without sales charges would be lower if sales charges were reflected. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Currentmonth-end performance is available on the Fund’s website, wellsfargofunds.com.

Index returns do not include transaction costs associated with buying and selling securities, any mutual fund fees or expenses, or any taxes. It is not possible to invest directly in an index.

For Class A shares, the maximumfront-end sales charge is 5.75%. For Class C shares, the maximum contingent deferred sales charge is 1.00%. Performance including a contingent deferred sales charge assumes the sales charge for the corresponding time period. Class R6, Administrator Class, and Institutional Class shares are sold without afront-end sales charge or contingent deferred sales charge.

Stock values fluctuate in response to the activities of individual companies and general market and economic conditions. Smaller-company stocks tend to be more volatile and less liquid than those of larger companies. Certain investment strategies tend to increase the total risk of an investment (relative to the broader market). Consult the Fund’s prospectus for additional information on these and other risks.

¹  The Fund is a gateway feeder fund that invests substantially all of its assets in a single affiliated master portfolio of the Wells Fargo Master Trust with a substantially identical investment objective and substantially similar investment strategies. References to the investment activities of the Fund are intended to refer to the investment activities of the affiliated master portfolio in which it invests.

²  Historical performance shown for the Class R6 shares prior to their inception reflects the performance of the Institutional Class shares and includes the higher expenses applicable to Institutional Class shares. If these expenses had been included, returns for Class R6 shares would be higher. Historical performance shown for Institutional Class shares prior to their inception reflects the performance of Administrator Class shares and includes the higher expenses applicable to Administrator Class shares. If these expenses had not been included, returns for Institutional Class shares would be higher.

³  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

⁴  The manager has contractually committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s Total Annual Fund Operating Expenses After Fee Waivers at the amounts shown. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses from funds in which the affiliated master portfolio invests (if any), and extraordinary expenses are excluded from the expense cap. Net expenses from the affiliated master portfolio are included in the expense cap. Without this cap, the Fund’s returns would have been lower. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁵  The Russell 2000^® Value Index measures the performance of those Russell 2000 companies with lower price/book ratios and lower forecasted growth values. You cannot invest directly in an index.

⁶  The ten largest holdings, excluding cash, cash equivalents and any money market funds, are calculated based on the value of the securities of the affiliated master portfolio allocable to the Fund divided by the total net assets of the Fund. Holdings are subject to change and may have changed since the date specified.

⁷  Amounts represent the sector distribution of the affiliated master portfolio which are calculated based on the total long-term investments of the affiliated master portfolio. These amounts are subject to change and may have changed since the date specified.

8 Wells Fargo Small Company Value Fund Fund expenses (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution(12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from June 1, 2018 to November 30, 2018.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

² Expenses paid is equal to the annualized net expense ratio of each class multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year divided by the number of days in the fiscal year (to reflect theone-half-year period).

18 Wells Fargo Small Company Value Fund Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Small Company Value Fund (the “Fund”) which is a diversified series of the Trust.

The Fund is a feeder fund in a master-feeder structure that invests substantially all of its assets in a single master portfolio with a substantially identical investment objective and substantially similar investment strategies. The Fund seeks to achieve its investment objective by investing all investable assets in a separate diversified portfolio (the “affiliated Master Portfolio”) of Wells Fargo Master Trust, a registeredopen-end management investment company. The affiliated Master Portfolio directly acquires portfolio securities and the Fund acquires an indirect interest in those securities. The Fund accounts for its investment in the affiliated Master Portfolio as a partnership investment and records on a daily basis its share of the affiliated Master Portfolio’s income, expense and realized and unrealized gains and losses. The financial statements of the affiliated Master Portfolio for the six months ended November 30, 2018 are included in this report and should be read in conjunction with the Fund’s financial statements. As of November 30, 2018, the Fund owned 48% of Wells Fargo Small Company Value Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation time under unusual or unexpected circumstances.

Investments in the affiliated Master Portfolio are valued daily based on the Fund’s proportionate share of the affiliated Master Portfolio’s net assets, which are also valued daily. Securities held in the affiliated Master Portfolio are valued as discussed in the Notes to Financial Statements of the affiliated Master Portfolio, which are included elsewhere in this report.

Investment transactions, income and expenses

Investments in the affiliated Master Portfolio are recorded on a trade basis.

The Fund records daily its proportionate share of the affiliated Master Portfolio’s interest and dividend income, expenses and realized and unrealized gains or losses. The Fund also accrues its own expenses.

Distributions to shareholders

Distributions to shareholders from net investment income and any net realized gains are recorded on theex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Notes to financial statements (unaudited) Wells Fargo Small Company Value Fund 19

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $88,793,050 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	0
Gross unrealized losses		(5,931,016	)
Net unrealized losses	$	(5,931,016	)

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

At November 30, 2018, the affiliated Master Portfolio was measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The investment objective and the value of the affiliate Master Portfolio was as follows:

Affiliated Master Portfolio	Investment objective	Value of affiliated Master Portfolio
Wells Fargo Small Company Value Portfolio	Seeks long-term capital appreciation		$82,862,034

The affiliated Master Portfolio does not have a redemption period notice, can be redeemed daily and does not have any unfunded commitments.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Wells Fargo Funds Management, LLC (“Funds Management”), an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser, and providing fund-level administrative services in connection with the Fund’s operations. As long as the Fund continues to invest substantially all of its assets in a single affiliated Master Portfolio, the Fund pays Funds Management an investment management fee only for fund-level administrative services at an annual rate starting at 0.05% and declining to 0.03% as the average daily net assets of the Fund increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.05% of the Fund’s average daily net assets.

Funds Management also serves as the adviser to the affiliated Master Portfolio and is entitled to receive a fee from the affiliated Master Portfolio for those services.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C		0.21	%
Class R6		0.03
Administrator Class, Institutional Class		0.13

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against

20 Wells Fargo Small Company Value Fund Notes to financial statements (unaudited)

class specific expenses before fund level expenses. Net expenses from the affiliated Master Portfolio are included in the expense cap. Funds Management has committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 1.15% for Class A shares, 1.90% for Class C shares, 0.75% for Class R6 shares, 1.05% for Administrator Class shares, and 0.85% for Institutional Class shares. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Distribution fee

The Trust has adopted a distribution plan for Class C shares of the Fund pursuant to Rule12b-1 under the 1940 Act. A distribution fee is charged to Class C shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares.

In addition, Funds Distributor is entitled to receive thefront-end sales charge from the purchase of Class A shares and a contingent deferred sales charge on the redemption of certain Class A shares. Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. For the six months ended November 30, 2018, Funds Distributor received $786 from the sale of Class A shares. Funds Distributor did not receive any contingent deferred sales charges from Class A or Class C shares for the six months ended November 30, 2018.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Class C, and Administrator Class of the Fund are charged a fee at an annual rate of 0.25% of the average daily net assets of each respective class.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

5. INVESTMENT PORTFOLIO TRANSACTIONS

The Fund seeks to achieve its investment objective by investing substantially all of its investable assets in a single affiliated Master Portfolio. Purchases and sales have been calculated by multiplying the Fund’s ownership percentage of the affiliated Master Portfolio by the affiliated Master Portfolio’s purchases and sales. Purchases and sales of investments, excluding short-term securities, for the six months ended November 30, 2018 were $98,127,722 and $82,681,488, respectively.

6. BANK BORROWINGS

The Trust (excluding the money market funds), Wells Fargo Master Trust and Wells Fargo Variable Trust are parties to a $280,000,000 revolving credit agreement whereby the Fund is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Fund based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Fund under the agreement.

7. DISTRIBUTIONS TO SHAREHOLDERS

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders. The amounts of distributions to shareholders for the year ended May 31, 2018 were as follows:

	Net investment income
Class A		$  52,718
Class R6		2,568
Administrator Class,		283,478
Institutional Class		383,137

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

Notes to financial statements (unaudited) Wells Fargo Small Company Value Portfolio 33

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Small Company Value Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Equity securities that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Investments in registeredopen-end investment companies are valued at net asset value. Interests innon-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”).The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in

34 Wells Fargo Small Company Value Portfolio Notes to financial statements (unaudited)

high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund is included in securities lending income from affiliates (net of fees and rebates) on the Statement of Operations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Dividend income is recognized on theex-dividend date. Dividend income is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $179,231,246 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	0
Gross unrealized losses		(1,061,491	)
Net unrealized losses	$	(1,061,491	)

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible forday-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.80% and declining to 0.68% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.80% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. WellsCap is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.55% and declining to 0.40% as the average daily net assets of the Portfolio increase.

Funds Management has voluntarily waived and/or reimbursed advisory fees to the extent necessary to maintain the net operating expense ratio of the Portfolio.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding U.S. government obligations (if any) and short-term securities, for the six months ended November 30, 2018 were $206.524,178 and $174,015,314, respectively.

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use

36 Wells Fargo Small Company Value Portfolio Notes to financial statements (unaudited)

bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

8. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo Core Bond Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the third quarter of 2018.

Dear Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo Core Bond Fund for thesix-month period that ended November 30, 2018. During the reporting period, the U.S. generated encouraging economic and business data that was offset by less positive and more inconsistent data from international markets. Investment returns were restrained in comparison with recent periods as geopolitical tensions and uncertainty tended to distract investors from more favorable underlying trends.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ gained 3.02% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 8.37%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 9.89%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ declined 0.30% while the Bloomberg Barclays Global Aggregateex-USD Index⁵ fell 3.67%. The Bloomberg Barclays Municipal Bond Index⁶ gained 0.42%. The ICE BofAML U.S. High Yield Index⁷ was up 0.19%.

Global trade tensions prompted investor concerns.

Global trade tensions escalated during the third quarter of 2018. The U.S. government’s decision during the second quarter to impose tariffs on a wide range of products manufactured overseas drew retaliatory responses from foreign governments, which punished U.S. commodity producers and product manufacturers. Investors were left to wonder about next steps in what appeared to be an escalating divergence in global economic policies and growth prospects.

Inflation trended higher. TheCPI-U⁸ added 0.1% in September after an increase of 0.2% in both July and August. On a year-over-year basis, theall-items index rose 2.3% for the 12 months that ended September 30, 2018, after a seasonal adjustment. The rate of increase was slower than that recorded during the first half of 2018. The index for all items less food and energy rose 2.2% for the same12-month period.

Letter to shareholders (unaudited) Wells Fargo Core Bond Fund 3

U.S. stocks gained following positive economic data while international stocks and bonds declined.

During the summer months, the U.S. economy strengthened. Revised second-quarter gross domestic product (GDP) data released in August showed the U.S. economy growing at a 4.2% rate. The unemployment rate in the U.S. was 3.7% by the end of September, according to the U.S. Department of Labor. Wages showed more consistent growth, and consumer confidence remained strong. Several U.S. equity market indices reached records during August, with the S&P 500 Index gaining 7.20% for the three-month period that ended September 30, 2018. In contrast, the MSCI ACWI ex USA Index (Net) gained 0.71% while the MSCI EM Index (Net) declined 1.09% during the same three-month period.

In June, the Federal Reserve increased the target range for the federal funds rate to range from 1.75% to 2.00%. It raised the range again in September to range from 2.00% to 2.25%. Long-term interest rates in the U.S. remained at higher levels relative to the prior 10 years. Rates on10-year and30-year Treasury bonds—2.46% and 2.81%, respectively, on January 1, 2018—were 3.01% and 3.30%, respectively, on November 30, 2018. Investor concerns about an inverted yield curve reemerged, only to be replaced by concerns about the potentially negative influence of higher interest rates on economic activity.

November saw improvement in many equity markets.

As interest rates and bond yields gained during October, stock markets struggled. For the month, the S&P 500 Index fell 6.84%, the MSCI ACWI ex USA Index (Net) dropped 8.13%, and the MSCI EM Index (Net) lost 8.71%. The Bureau of Economic Analysis released its first estimate of third-quarter GDP, which, at an annualized 3.5% rate, indicated growth may be slowing compared with the second quarter. Readings on consumer sentiment and business spending were mixed. Markets rebounded somewhat in November as the S&P 500 Index gained 2.04%, the MSCI ACWI ex USA Index (Net) added 0.95%, and the MSCI EM Index (Net) was up 4.12% as the uncertainty leading up to midterm elections in the U.S. was resolved and progress seemed to be possible on several international trade issues.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began. In early August, the Bank of England’s Monetary Policy Committee increased its key interest rate to 0.75%. The European Central Bank and the Bank of Japan maintained low interest rates and accommodative monetary policies. Amid rising trade uncertainty, the People’s Bank of China cut reserve requirement ratios and accelerated infrastructure spending and tax cuts for business enterprises and individuals. Nevertheless, a strengthening U.S. dollar and the trade tensions remained headwinds for investors overseas.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began.

Notice to shareholders

At a meeting held on August 14-15, 2018, the Board of Trustees of the Fund approved the following policy which will be effective on or about February 5, 2019:

Class C shares will convert automatically into Class A shares ten years after the initial date of purchase or, if you acquired your Class C shares through an exchange or conversion from another share class, ten years after the date you acquired your Class C shares. When Class C shares that you acquired through a purchase or exchange convert, any other Class C shares that you purchased with reinvested dividends and distributions also will convert into Class A shares on a pro rata basis. A shorter holding period may also apply depending on your intermediary. Please see “Appendix A—Sales Charge Reductions and Waivers for Certain Intermediaries” in the Fund’s prospectus or at the end of this report.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the redemption of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance shown without sales charges would be lower if sales charges were reflected. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Currentmonth-end performance is available on the Fund’s website, wellsfargofunds.com.

Index returns do not include transaction costs associated with buying and selling securities, any mutual fund fees or expenses, or any taxes. It is not possible to invest directly in an index.

For Class A shares, the maximumfront-end sales charge is 4.50%. For Class C shares, the maximum contingent deferred sales charge is 1.00%. Performance including a contingent deferred sales charge assumes the sales charge for the corresponding time period. Class R, Class R4, Class R6, Administrator Class, and Institutional Class shares are sold without afront-end sales charge or contingent deferred sales charge.

Bond values fluctuate in response to the financial condition of individual issuers, general market and economic conditions, and changes in interest rates. Changes in market conditions and government policies may lead to periods of heightened volatility in the bond market and reduced liquidity for certain bonds held by the Fund. In general, when interest rates rise, bond values fall and investors may lose principal value. Interest-rate changes and their impact on the Fund and its share price can be sudden and unpredictable. The use of derivatives may reduce returns and/or increase volatility. Certain investment strategies tend to increase the total risk of an investment (relative to the broader market). Securities issued by U.S. government agencies or government-sponsored entities may not be guaranteed by the U.S. Treasury. The Fund is exposed to foreign investment risk and mortgage- and asset-backed securities risk. Consult the Fund’s prospectus for additional information on these and other risks.

¹  The Fund is a gateway feeder fund that invests substantially all of its assets in a single affiliated master portfolio of the Wells Fargo Master Trust with a substantially identical investment objective and substantially similar investment strategies. References to the investment activities of the Fund are intended to refer to the investment activities of the affiliated master portfolio in which it invests.

²  Historical performance shown for Class R shares prior to their inception reflects the performance of Administrator Class shares, adjusted to reflect the higher expenses applicable to Class R shares. Historical performance shown for Class R4 shares prior to their inception reflects the performance of Institutional Class shares, adjusted to reflect the higher expenses applicable to Class R4 shares. Historical performance shown for Class R6 shares prior to their inception reflects the performance of Institutional Class shares and includes the higher expenses applicable to Institutional Class shares. If these expenses had not been included, returns for Class R6 shares would be higher.

³  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

⁴  The manager has contractually committed through September 30, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s Total Annual Fund Operating Expenses After Fee Waivers at the amounts shown. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any) from funds in which the affiliated master portfolio invests, and extraordinary expenses are excluded from the expense cap. Net expenses from the affiliated master portfolio are included in the expense cap. Without this cap, the Fund’s returns would have been lower. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁵  The Bloomberg Barclays U.S. Aggregate Bond Index is a broad-based benchmark that measures the investment-grade, U.S. dollar–denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable-rate mortgage pass-throughs), asset-backed securities, and commercial mortgage-backed securities. You cannot invest directly in an index.

⁶  The ten largest holdings, excluding cash, cash equivalents and any money market funds, are calculated based on the value of the securities of the affiliated master portfolio allocable to the Fund divided by the total net assets of the Fund.

8 Wells Fargo Core Bond Fund Fund expenses (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution(12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of thesix-month period and held for the entire period from June 1, 2018 to November 30, 2018.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

20 Wells Fargo Core Bond Fund Notes to financial statements (unaudited)

1. ORGANIZATION

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Core Bond Fund (the “Fund”) which is a diversified series of the Trust.

The Fund is a feeder fund in a master-feeder structure that invests substantially all of its assets in a single master portfolio with a substantially identical investment objective and substantially similar investment strategies. The Fund seeks to achieve its investment objective by investing all investable assets in a separate diversified portfolio (the “affiliated Master Portfolio”) of Wells Fargo Master Trust, a registeredopen-end management investment company. The affiliated Master Portfolio directly acquires portfolio securities and the Fund acquires an indirect interest in those securities. The Fund accounts for its investment in the affiliated Master Portfolio as a partnership investment and records on a daily basis its share of the affiliated Master Portfolio’s income, expense and realized and unrealized gains and losses. The financial statements of the affiliated Master Portfolio for the six months ended November 30, 2018 are included in this report and should be read in conjunction with the Fund’s financial statements. As of November 30, 2018, the Fund owned 92% of Wells Fargo Core Bond Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation time under unusual or unexpected circumstances.

Investments in the affiliated Master Portfolio are valued daily based on the Fund’s proportionate share of the affiliated Master Portfolio’s net assets, which are also valued daily. Securities held in the affiliated Master Portfolio are valued as discussed in the Notes to Financial Statements of the affiliated Master Portfolio, which are included elsewhere in this report.

Investment transactions, income and expenses

Investments in the affiliated Master Portfolio are recorded on a trade basis.

The Fund records daily its proportionate share of the affiliated Master Portfolio’s interest income, expenses and realized and unrealized gains or losses. The Fund also accrues its own expenses.

Distributions to shareholders

Distributions to shareholders from net investment income are declared daily and paid monthly. Distributions from net realized gains, if any, are recorded on the ex-dividend date and paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Notes to financial statements (unaudited) Wells Fargo Core Bond Fund 21

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $5,246,291,065 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	0
Gross unrealized losses		(93,544,482	)
Net unrealized losses	$	(93,544,482	)

As of May 31, 2018, the Fund had capital loss carryforwards which consist of $38,917,295 in short-term capital losses.

As of May 31, 2018, the Fund had current year deferred post-October capital losses consisting of $55,203,707 which were recognized on the first day of the current fiscal year.

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

At November 30, 2018, the affiliated Master Portfolio was measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The investment objective and the value of the affiliate Master Portfolio was as follows:

Affiliated Master Portfolio	Investment objective	Value of affiliated Master Portfolio
Wells Fargo Core Bond Portfolio	Seeks total return, consisting of income and capital appreciation	$	5,152,746,583

The affiliated Master Portfolio does not have a redemption period notice, can be redeemed daily and does not have any unfunded commitments.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Wells Fargo Funds Management, LLC (“Funds Management”), an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser, and providing fund-level administrative services in connection with the Fund’s operations. As long as the Fund continues to invest substantially all of its assets in a single affiliated Master Portfolio, the Fund pays Funds Management an investment management fee only for fund-level administrative services at an annual rate starting at 0.05% and declining to 0.03% as the average daily net assets of the Fund increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.05% of the Fund’s average daily net assets.

Funds Management also serves as the adviser to the affiliated Master Portfolio and is entitled to receive a fee from the affiliated Master Portfolio for those services.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C, Class R		0.16	%
Class R4, Institutional Class		0.08
Class R6		0.03
Administrator Class		0.10

22 Wells Fargo Core Bond Fund Notes to financial statements (unaudited)

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Net expenses from the affiliated Master Portfolio are included in the expense cap. Funds Management has committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.78% for Class A shares, 1.53% for Class C shares, 1.03% for Class R shares, 0.52% for Class R4 shares, 0.37% for Class R6 shares, 0.70% for Administrator Class shares, and 0.42% for Institutional Class shares. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Distribution fees

The Trust has adopted a distribution plan for Class C and Class R shares of the Fund pursuant to Rule12b-1 under the 1940 Act. Distribution fees are charged to Class C and Class R shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares and 0.25% of the average daily net assets of Class R shares.

In addition, Funds Distributor is entitled to receive thefront-end sales charge from the purchase of Class A shares and a contingent deferred sales charge on the redemption of certain Class A shares. Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. For the six months ended November 30, 2018, Funds Distributor received $2,381 from the sale of Class A shares. Funds Distributor did not receive any contingent deferred sales charges from Class A or Class C shares for the six months ended November 30, 2018.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Class C, Class R and Administrator Class of the Fund are charged a fee at an annual rate of 0.25% of the average daily net assets of each respective class. Class R4 is charged a fee at an annual rate of 0.10% of its average daily net assets.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

5. INVESTMENT PORTFOLIO TRANSACTIONS

The Fund seeks to achieve its investment objective by investing substantially all of its investable assets in a single affiliated Master Portfolio. Purchases and sales have been calculated by multiplying the Fund’s ownership percentage of the affiliated Master Portfolio by the affiliated Master Portfolio’s purchases and sales. Purchases and sales of investments, excluding short-term securities, for the six months ended November 30, 2018 were as follows:

Purchases at cost		Sales proceeds
U.S. government	Non-U.S. government	U.S. government	Non-U.S. government
$13,620,244,376	$1,963,048,100	$13,708,500,058	$1,991,449,077

6. BANK BORROWINGS

The Trust (excluding the money market funds), Wells Fargo Master Trust and Wells Fargo Variable Trust are parties to a $280,000,000 revolving credit agreement whereby the Fund is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Fund based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Fund under the agreement.

7. DISTRIBUTIONS TO SHAREHOLDERS

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders. The amounts of distributions to shareholders for the year ended May 31, 2018 were as follows:

	Net investment income
Class A	$	6,146,453
Class C		561,310

Class R6		24,689,238
Administrator Class		6,023,458
Institutional Class		70,984,919

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820)Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

Notes to financial statements (unaudited) Wells Fargo Core Bond Portfolio 51

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Core Bond Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Debt securities are valued at the evaluated bid price provided by an independent pricing service service (e.g. taking into account various factors, including yields, maturities, or credit ratings) or, if a reliable price is not available, the quoted bid price from an independent broker-dealer.

The values of securities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”).

Investments in registeredopen-end investment companies are valued at net asset value. Interests innon-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees of the Portfolio. The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee.The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Foreign currency translation

The accounting records of the Portfolio are maintained in U.S. dollars. The values of other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee. Purchases and sales of securities, and income and expenses are converted at the rate of exchange on the respective dates of such transactions. Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually paid or received. Net unrealized foreign exchange gains and losses arise from changes in the fair value of assets and liabilities other than investments in securities resulting from changes in exchange rates. The changes in net assets arising from changes in exchange rates of securities and the changes in net assets resulting from changes in market prices of securities are not separately presented. Such changes are included in net realized and unrealized gains or losses from investments.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of

52 Wells Fargo Core Bond Portfolio Notes to financial statements (unaudited)

each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund, if any, is included in income from affiliated securities on the Statement of Operations.

When-issued transactions

The Portfolio may purchase securities on a forward commitment or when-issued basis. The Portfolio records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Portfolio’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis are marked-to-market daily and the Portfolio begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily.To the extent debt obligations are placed onnon-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed fromnon-accrual status.

Income from foreign securities is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $5,819,208,917 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	16,606,387
Gross unrealized losses		(90,035,238	)
Net unrealized losses	$	(73,428,851	)

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Portfolio’s assets and liabilities as of November 30, 2018:

	Quoted prices (Level 1)		Other significant observable inputs (Level 2)		Significant unobservable inputs (Level 3)		Total

At November 30, 2018, the Portfolio did not have any transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible forday-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.40% and declining to 0.29% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.34% of the Portfolio’s average daily net assets.

54 Wells Fargo Core Bond Portfolio Notes to financial statements (unaudited)

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. WellsCap is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.20% and declining to 0.10% as the average daily net assets of the Portfolio increase.

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant to Rule17a-7 under the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding short-term securities, for the six months ended November 30, 2018 were as follows:

Purchases at cost		Sales proceeds
U.S. government	Non-U.S. government	U.S. government	Non-U.S. government
$14,734,145,798	$2,123,591,627	$14,829,619,275	$2,154,315,315

6. BANK BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

7. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolio and, therefore, cannot be estimated.

8. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management has adopted the removal and modification of disclosures early, as permitted, and will adopt the additional new disclosures at the effective date.

2 Wells Fargo Real Return Fund Letter to shareholders (unaudited)

Andrew Owen

President

Wells Fargo Funds

Global trade tensions escalated during the third quarter of 2018.

Dear Shareholder:

We are pleased to offer you this semi-annual report for the Wells Fargo Real Return Fund for the six-month period that ended November 30, 2018. During the reporting period, the U.S. generated encouraging economic and business data that was offset by less positive and more inconsistent data from international markets. Investment returns were restrained in comparison with recent periods as geopolitical tensions and uncertainty tended to distract investors from more favorable underlying trends.

For the period, U.S. stocks, as measured by the S&P 500 Index,¹ gained 3.02% and international stocks, as measured by the MSCI ACWI ex USA Index (Net),² declined 8.37%. Based on the MSCI EM Index (Net),³ emerging market stocks lost 9.89%. For bond investors, the Bloomberg Barclays U.S. Aggregate Bond Index⁴ declined 0.30% while the Bloomberg Barclays Global Aggregate ex-USD Index⁵ fell 3.67%. The Bloomberg Barclays Municipal Bond Index⁶ gained 0.42%. The ICE BofAML U.S. High Yield Index⁷ was up 0.19%.

Global trade tensions prompted investor concerns.

Global trade tensions escalated during the third quarter of 2018. The U.S. government’s decision during the second quarter to impose tariffs on a wide range of products manufactured overseas drew retaliatory responses from foreign governments, which punished U.S. commodity producers and product manufacturers. Investors were left to wonder about next steps in what appeared to be an escalating divergence in global economic policies and growth prospects.

Inflation trended higher. The CPI-U⁸ added 0.1% in September after an increase of 0.2% in both July and August. On a year-over-year basis, the all-items index rose 2.3% for the 12 months that ended September 30, 2018, after a seasonal adjustment. The rate of increase was slower than that recorded during the first half of 2018. The index for all items less food and energy rose 2.2% for the same 12-month period.

¹  The S&P 500 Index consists of 500 stocks chosen for market size, liquidity, and industry group representation. It is a market-value-weighted index with each stock’s weight in the index proportionate to its market value. You cannot invest directly in an index.

²  The Morgan Stanley Capital International (MSCI) All Country World Index (ACWI) ex USA Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure the equity market performance of developed markets, excluding the U.S. and Canada. Source: MSCI. MSCI makes no express or implied warranties or representations and shall have no liability whatsoever with respect to any MSCI data contained herein. The MSCI data may not be further redistributed or used as a basis for other indices or any securities or financial products. This report is not approved, reviewed, or produced by MSCI. You cannot invest directly in an index.

³  The MSCI Emerging Markets (EM) Index (Net) is a free-float-adjusted market-capitalization-weighted index that is designed to measure large- and mid-cap equity market performance of emerging markets. The MSCI EM Index (Net) consists of the following 24 emerging market country indices: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, the Philippines, Poland, Qatar, Russia, South Africa, Taiwan, Thailand, Turkey, and the United Arab Emirates. You cannot invest directly in an index.

⁴  The Bloomberg Barclays U.S. Aggregate Bond Index is a broad-based benchmark that measures the investment-grade, U.S.-dollar-denominated, fixed-rate taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid adjustable-rate mortgage pass-throughs), asset-backed securities, and commercial mortgage-backed securities. You cannot invest directly in an index.

⁵  The Bloomberg Barclays Global Aggregate ex-USD Index is an unmanaged index that provides a broad-based measure of the global investment-grade fixed-income markets excluding the U.S.-dollar-denominated debt market. You cannot invest directly in an index.

⁶  The Bloomberg Barclays Municipal Bond Index is an unmanaged index composed of long-term tax-exempt bonds with a minimum credit rating of Baa. You cannot invest directly in an index.

⁷  The ICE BofAML U.S. High Yield Index is a market-capitalization-weighted index of domestic and Yankee high-yield bonds. The index tracks the performance of high-yield securities traded in the U.S. bond market. You cannot invest directly in an index. Copyright 2018. ICE Data Indices, LLC. All rights reserved.

⁸  The Consumer Price Index for All Urban Consumers (CPI-U) measures the changes in the price of a basket of goods and services purchased by urban consumers. The urban consumer population is deemed by many as a better representative measure of the general public because close to 90% of the country’s population lives in highly populated areas. You cannot invest directly in an index.

Letter to shareholders (unaudited) Wells Fargo Real Return Fund 3

U.S. stocks gained following positive economic data while international stocks and bonds declined.

During the summer months, the U.S. economy strengthened. Revised second-quarter gross domestic product (GDP) data released in August showed the U.S. economy growing at a 4.2% rate. The unemployment rate in the U.S. was 3.7% by the end of September, according to the U.S. Department of Labor. Wages showed more consistent growth, and consumer confidence remained strong. Several U.S. equity market indices reached records during August, with the S&P 500 Index gaining 7.20% for the three-month period that ended September 30, 2018. In contrast, the MSCI ACWI ex USA Index (Net) gained 0.71% while the MSCI EM Index (Net) declined 1.09% during the same three-month period.

In June, the Federal Reserve increased the target range for the federal funds rate to range from 1.75% to 2.00%. It raised the range again in September to range from 2.00% to 2.25%. Long-term interest rates in the U.S. remained at higher levels relative to the prior 10 years. Rates on 10-year and 30-year Treasury bonds—2.46% and 2.81%, respectively, on January 1, 2018—were 3.01% and 3.30%, respectively, on November 30, 2018. Investor concerns about an inverted yield curve reemerged, only to be replaced by concerns about the potentially negative influence of higher interest rates on economic activity.

November saw improvement in many equity markets.

As interest rates and bond yields gained during October, stock markets struggled. For the month, the S&P 500 Index fell 6.84%, the MSCI ACWI ex USA Index (Net) dropped 8.13%, and the MSCI EM Index (Net) lost 8.71%. The Bureau of Economic Analysis released its first estimate of third-quarter GDP, which, at an annualized 3.5% rate, indicated growth may be slowing compared with the second quarter. Readings on consumer sentiment and business spending were mixed. Markets rebounded somewhat in November as the S&P 500 Index gained 2.04%, the MSCI ACWI ex USA Index (Net) added 0.95%, and the MSCI EM Index (Net) was up 4.12% as the uncertainty leading up to midterm elections in the U.S. was resolved and progress seemed to be possible on several international trade issues.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began. In early August, the Bank of England’s Monetary Policy Committee increased its key interest rate to 0.75%. The European Central Bank and the Bank of Japan maintained low interest rates and accommodative monetary policies. Amid rising trade uncertainty, the People’s Bank of China cut reserve requirement ratios and accelerated infrastructure spending and tax cuts for business enterprises and individuals. Nevertheless, a strengthening U.S. dollar and the trade tensions remained headwinds for investors overseas.

Don’t let short-term uncertainty derail long-term investment goals.

Periods of investment uncertainty can present challenges, but experience has taught us that maintaining long-term investment goals can be an effective way to plan for the future. To help you create a sound strategy based on your personal goals and risk tolerance, Wells Fargo Funds offers more than 100 mutual funds spanning a wide range of asset classes and investment styles. Although diversification cannot guarantee an investment profit or prevent losses, we believe it can be an effective way to manage investment risk and potentially smooth out overall portfolio performance. We encourage investors to know their investments and to understand that appropriate levels of risk-taking may unlock opportunities.

Economic signals overseas were mixed as the third quarter ended and the fourth quarter began.

Figures quoted represent past performance, which is no guarantee of future results, and do not reflect taxes that a shareholder may pay on fund distributions or the redemption of fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Performance shown without sales charges would be lower if sales charges were reflected. Current performance may be lower or higher than the performance data quoted, which assumes the reinvestment of dividends and capital gains. Current month-end performance is available on the Fund’s website, wellsfargofunds.com.

Index returns do not include transaction costs associated with buying and selling securities, any mutual fund fees or expenses, or any taxes. It is not possible to invest directly in an index.

For Class A shares, the maximum front-end sales charge is 4.50%. For Class C shares, the maximum contingent deferred sales charge is 1.00%. Performance including a contingent deferred sales charge assumes the sales charge for the corresponding time period. Class R6, Administrator Class, and Institutional Class shares are sold without a front-end sales charge or contingent deferred sales charge.

Bond values fluctuate in response to the financial condition of individual issuers, general market and economic conditions, and changes in interest rates. Changes in market conditions and government policies may lead to periods of heightened volatility in the bond market and reduced liquidity for certain bonds held by the Fund. In general, when interest rates rise, bond values fall and investors may lose principal value. Interest rate changes and their impact on the Fund and its share price can be sudden and unpredictable. Stock values fluctuate in response to the activities of individual companies and general market and economic conditions. High-yield securities have a greater risk of default and tend to be more volatile than higher-rated debt securities. Loans are subject to risks similar to those associated with other below investment-grade bond investments, such as credit risk (for example, risk of issuer default), below-investment-grade bond risk (for example, risk of greater volatility in value), and risk that the loan may become illiquid or difficult to price. The use of derivatives may reduce returns and/or increase volatility. Foreign investments are especially volatile and can rise or fall dramatically due to differences in the political and economic conditions of the host country. These risks are generally intensified in emerging markets. The Fund is exposed to mortgage- and asset-backed securities risk and small company securities risk. Securities issued by U.S. government agencies or government-sponsored entities may not be guaranteed by the U.S. Treasury. Consult the Fund’s prospectus for additional information on these and other risks.

Please see footnotes on page 7.

¹  The Fund is a gateway feeder fund that invests substantially all of its assets in a single affiliated master portfolio of the Wells Fargo Master Trust with a substantially identical investment objective and substantially similar investment strategies. References to the investment activities of the Fund are intended to refer to the investment activities of the affiliated master portfolio in which it invests.

²  Historical performance shown for the Class R6 shares prior to their inception reflects the performance of the Administrator Class shares, and is not adjusted to reflect Class R6 expenses. If these expenses had been included, returns for Class R6 shares would be higher. Historical performance shown for the Institutional Class shares prior to their inception reflects the performance of the Administrator Class shares, and is not adjusted to reflect Institutional Class expenses. If these expenses had not been included, returns for the Institutional Class shares would be higher.

³  Reflects the expense ratios as stated in the most recent prospectuses. The expense ratios shown are subject to change and may differ from the annualized expense ratios shown in the financial highlights of this report.

⁴  The manager has contractually committed through September 30, 2019, to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s Total Annual Fund Operating Expenses After Fee Waivers at the amounts shown. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees. Brokerage commissions, stamp duty fees, interest, taxes, acquired fund fees and expenses (if any) from funds in which the underlying affiliated master portfolio invests, and extraordinary expenses are excluded from the expense cap. Net expenses from the affiliated master portfolio are included in the expense cap. Without this cap, the Fund’s returns would have been lower. The expense ratio paid by an investor is the net expense ratio (the total annual fund operating expenses after fee waivers) as stated in the prospectuses.

⁵  The Bloomberg Barclays U.S. Treasury Inflation-Protected Securities (TIPS) Index is an index of inflation-indexed-linked U.S. Treasury securities. You cannot invest directly in an index.

⁶  The Consumer Price Index (CPI) for All Urban Consumers in U.S. is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. You cannot invest directly in an index.

⁷  The ten largest holdings, excluding cash, cash equivalents and any money market funds, are calculated based on the value of the securities of the affiliated master portfolio allocable to the Fund divided by the total net assets of the Fund.

8 Wells Fargo Real Return Fund Fund expenses (unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and contingent deferred sales charges (if any) on redemptions and (2) ongoing costs, including management fees, distribution (12b-1) and/or shareholder servicing fees, and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period from June 1, 2018 to November 30, 2018.

Actual expenses

The “Actual” line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the “Actual” line under the heading entitled “Expenses paid during period” for your applicable class of shares to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The “Hypothetical” line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and contingent deferred sales charges. Therefore, the “Hypothetical” line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Wells Fargo Funds Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Real Return Fund (the “Fund”) which is a diversified series of the Trust.

The Fund is a feeder fund in a master-feeder structure that invests substantially all of its assets in a single master portfolio with a substantially identical investment objective and substantially similar investment strategies. The Fund seeks to achieve its investment objective by investing all investable assets in a separate diversified portfolio (the “affiliated Master Portfolio”) of Wells Fargo Master Trust, a registeredopen-end management investment company. The affiliated Master Portfolio directly acquires portfolio securities and the Fund acquires an indirect interest in those securities. The Fund accounts for its investment in the affiliated Master Portfolio as a partnership investment and records on a daily basis its share of the affiliated Master Portfolio’s income, expense and realized and unrealized gains and losses. The financial statements of the affiliated Master Portfolio for the six months ended November 30, 2018 are included in this report and should be read in conjunction with the Fund’s financial statements. As of November 30, 2018, the Fund owned 33% of Wells Fargo Real Return Portfolio.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Fund, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Fund may deviate from this calculation time under unusual or unexpected circumstances.

Investments in the affiliated Master Portfolio are valued daily based on the Fund’s proportionate share of the affiliated Master Portfolio’s net assets, which are also valued daily. Securities held in the affiliated Master Portfolio are valued as discussed in the Notes to Financial Statements of the affiliated Master Portfolio, which are included elsewhere in this report.

Investment transactions, income and expenses

Investments in the affiliated Master Portfolio are recorded on a trade basis.

The Fund records daily its proportionate share of the affiliated Master Portfolio’s interest and dividend income, expenses and realized and unrealized gains or losses. The Fund also accrues its own expenses.

Distributions to shareholders

Distributions to shareholders are recorded on theex-dividend date and paid from net investment income monthly and any net realized gains are paid at least annually. Such distributions are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles. Dividend sources are estimated at the time of declaration. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made prior to the Fund’s fiscal year end may be categorized as a tax return of capital at year end.

Federal and other taxes

The Fund intends to continue to qualify as a regulated investment company by distributing substantially all of its investment company taxable income and any net realized capital gains (after reduction for capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income taxes. Accordingly, no provision for federal income taxes was required.

The Fund’s income and federal excise tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal and Delaware revenue authorities. Management has analyzed the Fund’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

Notes to financial statements (unaudited) Wells Fargo Real Return Fund 19

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $65,521,116 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	1,162,070
Gross unrealized losses		0
Net unrealized gains	$	1,162,070

Class allocations

The separate classes of shares offered by the Fund differ principally in applicable sales charges, distribution, shareholder servicing, and administration fees. Class specific expenses are charged directly to that share class. Investment income, common expenses, and realized and unrealized gains (losses) on investments are allocated daily to each class of shares based on the relative proportion of net assets of each class.

3. FAIR VALUATION MEASUREMENTS

At November 30, 2018, the affiliated Master Portfolio was measured at fair value using the net asset value per share (or its equivalent) as a practical expedient. The investment objective and the value of the affiliate Master Portfolio was as follows:

Affiliated Master Portfolio	Investment objective	Value of affiliated Master Portfolio
Wells Fargo Real Return Portfolio	Seeks returns that exceed the rate of inflation over the long-term		$66,683,186

The affiliated Master Portfolio does not have a redemption period notice, can be redeemed daily and does not have any unfunded commitments.

4. TRANSACTIONS WITH AFFILIATES

Management fee

Wells Fargo Funds Management, LLC (“Funds Management”), an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”), is the manager of the Fund and provides advisory and fund-level administrative services under an investment management agreement. Under the investment management agreement, Funds Management is responsible for, among other services, implementing the investment objectives and strategies of the Fund, supervising the subadviser, and providing fund-level administrative services in connection with the Fund’s operations. As long as the Fund continues to invest substantially all of its assets in a single affiliated Master Portfolio, the Fund pays Funds Management an investment management fee only for fund-level administrative services at an annual rate starting at 0.05% and declining to 0.03% as the average daily net assets of the Fund increase. For the six months ended November 30, 2018, the management fee was equivalent to an annual rate of 0.05% of the Fund’s average daily net assets.

Funds Management also serves as the adviser to the affiliated Master Portfolio and is entitled to receive a fee from the affiliated Master Portfolio for those services.

Administration fees

Under a class-level administration agreement, Funds Management provides class-level administrative services to the Fund, which includes paying fees and expenses for services provided by the transfer agent,sub-transfer agents, omnibus account servicers and record-keepers. As compensation for its services under the class-level administration agreement, Funds Management receives an annual fee which is calculated based on the average daily net assets of each class as follows:

	Class-level administration fee
Class A, Class C		0.16	%
Class R6		0.03
Administrator Class		0.10
Institutional Class		0.08

20 Wells Fargo Real Return Fund Notes to financial statements (unaudited)

Funds Management has contractually waived and/or reimbursed management and administration fees to the extent necessary to maintain certain net operating expense ratios for the Fund. When each class of the Fund has exceeded its expense cap, Funds Management has waived fees and/or reimbursed expenses from fund level expenses on a proportionate basis and then from class specific expenses; otherwise, waivers and/or reimbursements are applied against class specific expenses before fund level expenses. Net expenses from the affiliated Master Portfolio are included in the expense cap. Funds Management has committed through September 30, 2019 to waive fees and/or reimburse expenses to the extent necessary to cap the Fund’s expenses at 0.78% for Class A shares, 1.53% for Class C shares, 0.40% for Class R6 shares, 0.60% for Administrator Class shares, and 0.45% for Institutional Class shares. After this time, the cap may be increased or the commitment to maintain the cap may be terminated only with the approval of the Board of Trustees.

Distribution fee

The Trust has adopted a distribution plan for Class C shares of the Fund pursuant to Rule12b-1 under the 1940 Act. A distribution fee is charged to Class C shares and paid to Wells Fargo Funds Distributor, LLC (“Funds Distributor”), the principal underwriter, at an annual rate of 0.75% of the average daily net assets of Class C shares.

In addition, Funds Distributor is entitled to receive thefront-end sales charge from the purchase of Class A shares and a contingent deferred sales charge on the redemption of certain Class A shares. Funds Distributor is also entitled to receive the contingent deferred sales charges from redemptions of Class C shares. For the six months ended November 30, 2018, Funds Distributor received $166 from the sale of Class A shares. No contingent deferred sales charges were incurred by Class A or Class C shares for the six months ended November 30, 2018.

Shareholder servicing fees

The Trust has entered into contracts with one or more shareholder servicing agents, whereby Class A, Class C, and Administrator Class of the Fund are charged a fee at an annual rate of 0.25% of the average daily net assets of each respective class.

A portion of these total shareholder servicing fees were paid to affiliates of Wells Fargo.

5. INVESTMENT PORTFOLIO TRANSACTIONS

The Fund seeks to achieve its investment objective by investing substantially all of its investable assets in a single affiliated Master Portfolio. Purchases and sales have been calculated by multiplying the Fund’s ownership percentage of the affiliated Master Portfolio by the affiliated Master Portfolio’s purchases and sales. Purchases and sales of investments, excluding short-term securities, for the six months ended November 30, 2018 were as follows:

Purchases at cost		Sales proceeds
U.S. government	Non-U.S. government	U.S. government	Non-U.S. government
$20,395,906	$12,239,748	$6,980,459	$3,963,226

6. BANK BORROWINGS

The Trust (excluding the money market funds), Wells Fargo Master Trust and Wells Fargo Variable Trust are parties to a $280,000,000 revolving credit agreement whereby the Fund is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Fund based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Funds under the agreement.

7. DISTRIBUTIONS TO SHAREHOLDERS

Effective for all filings after November 4, 2018, the Securities and Exchange Commission eliminated the requirement to separately state the components of distributions to shareholders. The amounts of distributions to shareholders for the year ended May 31, 2018 were as follows:

	Net investment income

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Fund and, therefore, cannot be estimated.

Notes to financial statements (unaudited) Wells Fargo Real Return Portfolio 39

1. ORGANIZATION

Wells Fargo Master Trust (the “Trust”), a Delaware statutory trust organized on March 10, 1999, is anopen-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As an investment company, the Trust follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”)Accounting Standards Codification Topic 946, Financial Services – Investment Companies. These financial statements report on the Wells Fargo Real Return Portfolio (the “Portfolio”) which is a diversified series of the Trust.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies, which are consistently followed in the preparation of the financial statements of the Portfolio, are in conformity with U.S. generally accepted accounting principles which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Securities valuation

All investments are valued each business day as of the close of regular trading on the New York Stock Exchange (generally 4 p.m. Eastern Time), although the Portfolio may deviate from this calculation time under unusual or unexpected circumstances.

Debt securities are valued at the evaluated bid price provided by an independent pricing service (e.g. taking into account various factors, including yields, maturities, or credit ratings) or, if a reliable price is not available, the quoted bid price from an independent broker-dealer.

Equity securities and futures contracts that are listed on a foreign or domestic exchange or market are valued at the official closing price or, if none, the last sales price. If no sale occurs on the principal exchange or market that day, a fair value price will be determined in accordance with the Portfolio’s Valuation Procedures.

Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange and therefore may not fully reflect trading or events that occur after the close of the principal exchange in which the foreign securities are traded, but before the close of the New York Stock Exchange. If such trading or events are expected to materially affect the value of such securities, then fair value pricing procedures approved by the Board of Trustees of the Portfolio are applied. These procedures take into account multiple factors including movements in U.S. securities markets after foreign exchanges close. Foreign securities that are fair valued under these procedures are categorized as Level 2 and the application of these procedures may result in transfers between Level 1 and Level 2. Depending on market activity, such fair valuations may be frequent. Such fair value pricing may result in net asset values that are higher or lower than net asset values based on the last reported sales price or latest quoted bid price. On November 30, 2018, such fair value pricing was not used in pricing foreign securities.

Investments in registeredopen-end investment companies are valued at net asset value. Interests innon-registered investment companies that are redeemable at net asset value are fair valued normally at net asset value.

Investments which are not valued using any of the methods discussed above are valued at their fair value, as determined in good faith by the Board of Trustees . The Board of Trustees has established a Valuation Committee comprised of the Trustees and has delegated to it the authority to take any actions regarding the valuation of portfolio securities that the Valuation Committee deems necessary or appropriate, including determining the fair value of portfolio securities, unless the determination has been delegated to the Wells Fargo Asset Management Pricing Committee at Wells Fargo Funds Management, LLC (“Funds Management”). The Board of Trustees retains the authority to make or ratify any valuation decisions or approve any changes to the Valuation Procedures as it deems appropriate. On a quarterly basis, the Board of Trustees receives reports on any valuation actions taken by the Valuation Committee or the Wells Fargo Asset Management Pricing Committee which may include items for ratification.

Foreign currency translation

The accounting records of the Portfolio are maintained in U.S. dollars. The values of other assets and liabilities denominated in foreign currencies are translated into U.S. dollars at rates provided by an independent foreign currency pricing source at a time each business day specified by the Wells Fargo Asset Management Pricing Committee. Purchases and sales of securities, and income and expenses are converted at the rate of exchange on the respective dates of such transactions. Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of

40 Wells Fargo Real Return Portfolio Notes to financial statements (unaudited)

dividends, interest and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually paid or received. Net unrealized foreign exchange gains and losses arise from changes in the fair value of assets and liabilities other than investments in securities resulting from changes in exchange rates. The changes in net assets arising from changes in exchange rates of securities and the changes in net assets resulting from changes in market prices of securities are not separately presented. Such changes are included in net realized and unrealized gains or losses from investments.

Participation notes

The Portfolio may invest in participation notes to gain exposure to securities in certain foreign markets. Participation notes are issued by banks or broker-dealers and are designed to offer a return linked to a particular underlying foreign security. Participation notes involve transaction costs, which may be higher than those applicable to the underlying foreign security. The holder of the participation note is entitled to receive from the bank or broker-dealer, an amount equal to the dividend paid by the issuer of the underlying foreign security; however, the holder is not entitled to the same rights (i.e. voting rights) as an owner of the underlying foreign security. Investments in participation notes involve risks beyond those normally associated with a direct investment in an underlying security. The Portfolio has no rights against the issuer of the underlying foreign security and participation notes expose the Portfolio to counterparty risk in the event the counterparty does not perform. There is also no assurance there will be a secondary trading market for the participation note or that the trading price of the participation note will equal the underlying value of the foreign security that it seeks to replicate.

Securities lending

The Portfolio may lend its securities from time to time in order to earn additional income in the form of fees or interest on securities received as collateral or the investment of any cash received as collateral. The Portfolio continues to receive interest or dividends on the securities loaned. The Portfolio receives collateral in the form of cash or securities with a value at least equal to the value of the securities on loan. The value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Portfolio on the next business day. In a securities lending transaction, the net asset value of the Portfolio will be affected by an increase or decrease in the value of the securities loaned and by an increase or decrease in the value of the instrument in which collateral is invested. The amount of securities lending activity undertaken by the Portfolio fluctuates from time to time. In the event of default or bankruptcy by the borrower, the Portfolio may be prevented from recovering the loaned securities or gaining access to the collateral or may experience delays or costs in doing so. In addition, the investment of any cash collateral received may lose all or part of its value. The Portfolio has the right under the lending agreement to recover the securities from the borrower on demand.

The Portfolio lends its securities through an unaffiliated securities lending agent. Cash collateral received in connection with its securities lending transactions is invested in Securities Lending Cash Investments, LLC (the “Securities Lending Fund”). The Securities Lending Fund is exempt from registration under Section 3(c)(7) of the 1940 Act and is managed by Funds Management and is subadvised by Wells Capital Management Incorporated (“WellsCap”), an affiliate of Funds Management and an indirect wholly owned subsidiary of Wells Fargo & Company (“Wells Fargo”). Funds Management receives an advisory fee starting at 0.05% and declining to 0.01% as the average daily net assets of the Securities Lending Fund increase. All of the fees received by Funds Management are paid to WellsCap for its services as subadviser. The Securities Lending Fund seeks to provide a positive return compared to the daily Fed Funds Open Rate by investing in high-quality, U.S. dollar-denominated short-term money market instruments. Securities Lending Fund investments are valued at the evaluated bid price provided by an independent pricing service. Income earned from investment in the Securities Lending Fund, if any, is included in income from affiliated securities on the Statement of Operations.

When-issued transactions

The Portfolio may purchase securities on a forward commitment or when-issued basis. A Portfolio records a when-issued transaction on the trade date and will segregate assets in an amount at least equal in value to the Portfolio’s commitment to purchase when-issued securities. Securities purchased on a when-issued basis aremarked-to-market daily and the Portfolio begins earning interest on the settlement date. Losses may arise due to changes in the market value of the underlying securities or if the counterparty does not perform under the contract.

Loans

The Portfolio may invest in direct debt instruments which are interests in amounts owed to lenders by corporate or other borrowers. The loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. Investments in loans may be in the form of participations in loans or assignments of all or a portion of loans from third parties. When the Portfolio purchases participations, it generally has no rights to enforce compliance with terms of the

Notes to financial statements (unaudited) Wells Fargo Real Return Portfolio 41

loan agreement with the borrower. As a result, the Portfolio assumes the credit risk of both the borrower and the lender that is selling the participation. When the Portfolio purchases assignments from lenders, it acquires direct rights against the borrower on the loan and may enforce compliance by the borrower with the terms of the loan agreement. Loans may include fully funded term loans or unfunded loan commitments, which are contractual obligations for future funding.

Futures contracts

The Portfolio is subject to interest rate risk in the normal course of pursuing its investment objectives. Futures contracts are agreements between the Portfolio and a counterparty to buy or sell a specific amount of a commodity, financial instrument or currency at specified price and on a specified date. The Portfolio may buy and sell futures contracts in order to gain exposure to, or protect against, changes in interest rates and security values. The primary risks associated with the use of futures contracts are the imperfect correlation between changes in market values of securities held by the Portfolio and the prices of futures contracts, and the possibility of an illiquid market. Futures contracts are generally entered into on a regulated futures exchange and cleared through a clearinghouse associated with the exchange. With futures contracts, there is minimal counter party risk to the Portfolio since futures contracts are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures contracts against default.

Upon entering into a futures contracts, the Portfolio is required to deposit either cash or securities (initial margin) with the broker in an amount equal to a certain percentage of the contract value. Subsequent payments (variation margin) are paid to or from the broker each day equal to the daily changes in the contract value. Such payments are recorded as unrealized gains or losses and, if any, shown as variation margin receivable (payable) in the Statement of Assets and Liabilities. Should the Portfolio fail to make requested variation margin payments, the broker can gain access to the initial margin to satisfy the Portfolio’s payment obligations. When the contracts are closed, a realized gain or loss is recorded in the Statement of Operations.

Inflation-indexed bonds and TIPS

The Portfolio may invest in inflation-indexed bonds, including Treasury inflation-protected securities (TIPS). Inflation-indexed bonds are fixed income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of inflation-indexed bonds (other than municipal inflation-indexed bonds and certain corporate inflation-indexed bonds) will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal. The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates are tied to the relationship between nominal interest rates and the rate of inflation. If nominal interest rates increase at a faster rate than inflation, real interest rates may rise, leading to a decrease in value of inflation-indexed bonds. Inflation-indexed bonds, including TIPS, decline in value when real interest rates rise. In certain interest rate environments, such as when real interest rates are rising faster than nominal interest rates, inflation-indexed bonds may experience greater losses than other fixed income securities with similar durations.

Security transactions and income recognition

Securities transactions are recorded on a trade date basis. Realized gains or losses are recorded on the basis of identified cost.

Interest income is accrued daily and bond discounts are accreted and premiums are amortized daily. To the extent debt obligations are placed onnon-accrual status, any related interest income may be reduced by writing off interest receivables when the collection of all or a portion of interest has been determined to be doubtful based on consistently applied procedures and the fair value has decreased. If the issuer subsequently resumes interest payments or when the collectability of interest is reasonably assured, the debt obligation is removed fromnon-accrual status.

Dividend income is recognized on theex-dividend date, except for certain dividends from foreign securities, which are recorded as soon as the custodian verifies theex-dividend date. Dividend income from foreign securities is recorded net of foreign taxes withheld where recovery of such taxes is not assured.

Federal and other taxes

The Portfolio is treated as a separate entity for federal income tax purposes. The Portfolio is not required to pay federal income taxes on its net investment income and net capital gains as it is treated as a partnership for federal income tax purposes. All interest, dividends, gains and losses of the Portfolio are deemed to have been “passed through” to the interest holders in proportion to their holdings of the Portfolio regardless of whether such interest, dividends and gains have been distributed by the Portfolio.

42 Wells Fargo Real Return Portfolio Notes to financial statements (unaudited)

The Portfolio’s income tax returns and all financial records supporting those returns for the prior three fiscal years are subject to examination by the federal revenue authority. Management has analyzed the Portfolio’s tax positions taken on federal, state, and foreign tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.

As of November 30, 2018, the aggregate cost of all investments for federal income tax purposes was $208,561,455 and the unrealized gains (losses) consisted of:

Gross unrealized gains	$	2,857,436
Gross unrealized losses		(6,844,437	)
Net unrealized losses	$	(3,987,001	)

3. FAIR VALUATION MEASUREMENTS

Fair value measurements of investments are determined within a framework that has established a fair value hierarchy based upon the various data inputs utilized in determining the value of the Portfolio’s investments. The three-level hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The Portfolio’s investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The inputs are summarized into three broad levels as follows:

∎ Level 1 – quoted prices in active markets for identical securities

∎ Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

∎ Level 3 – significant unobservable inputs (including the Portfolio’s own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing investments in securities are not necessarily an indication of the risk associated with investing in those securities.

All other assets and liabilities are reported at their market value at measurement date.

At November 30, 2018, the Portfolio has no material transfers into/out of Level 3.

4. TRANSACTIONS WITH AFFILIATES

Advisory fee

The Trust has entered into an advisory contract with Funds Management, an indirect wholly owned subsidiary of Wells Fargo. The adviser is responsible for implementing investment policies and guidelines and for supervising the subadviser, who is responsible forday-to-day portfolio management of the Portfolio. Pursuant to the contract, Funds Management is entitled to receive an annual advisory fee starting at 0.40% and declining to 0.29% as the average daily net assets of the Portfolio increase. For the six months ended November 30, 2018, the advisory fee was equivalent to an annual rate of 0.40% of the Portfolio’s average daily net assets.

Funds Management has retained the services of a subadviser to provide daily portfolio management to the Portfolio. The fee for subadvisory services is borne by Funds Management. WellsCap is the subadviser to the Portfolio and is entitled to receive a fee from Funds Management at an annual rate starting at 0.28% and declining to 0.18% as the average daily net assets of the Portfolio increase.

Funds Management has voluntarily waived and/or reimbursed advisory fees to the extent necessary to maintain certain net operating expense ratios for the Portfolio.

44 Wells Fargo Real Return Portfolio Notes to financial statements (unaudited)

Interfund transactions

The Portfolio may purchase or sell portfolio investment securities to certain other Wells Fargo affiliates pursuant toRule 17a-7 of the 1940 Act and under procedures adopted by the Board of Trustees. The procedures have been designed to ensure that these interfund transactions, which do not incur broker commissions, are effected at current market prices.

5. INVESTMENT PORTFOLIO TRANSACTIONS

Purchases and sales of investments, excluding short-term securities, for the six months ended November 30, 2018 were as follows:

Purchases at cost		Sales proceeds
U.S. government	Non-U.S. government	U.S. government	Non-U.S. government
$62,322,833	$37,400,436	$21,329,867	$12,110,246

6. DERIVATIVE TRANSACTIONS

During the six months ended November 30, 2018, the Portfolio entered into futures contract to speculate on interest rates and to help manage the duration of its portfolio. The Portfolio had an average notional amount of $2,023,638 in long futures contracts and $9,808,367 in short futures contracts during the six months ended November 30, 2018.

The fair value, realized gains or losses and change in unrealized gains or losses, if any, on derivative instruments are reflected in the corresponding financial statement captions.

7. BORROWINGS

Effective August 28, 2018, the Trust, along with Wells Fargo Variable Trust and Wells Fargo Funds Trust (excluding the money market funds), are parties to a $280,000,000 revolving credit agreement whereby the Portfolio is permitted to use bank borrowings for temporary or emergency purposes, such as to fund shareholder redemption requests. Interest under the credit agreement is charged to the Portfolio based on a borrowing rate equal to the higher of the Federal Funds rate in effect on that day plus 1.25% or the overnight LIBOR rate in effect on that day plus 1.25%. In addition, an annual commitment fee equal to 0.25% of the unused balance is allocated to each participating fund.

For the six months ended November 30, 2018, there were no borrowings by the Portfolio under the agreement.

8. INDEMNIFICATION

Under the Trust’s organizational documents, the officers and Trustees have been granted certain indemnification rights against certain liabilities that may arise out of performance of their duties to the Trust. Additionally, in the normal course of business, the Trust may enter into contracts with service providers that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Portfolios and, therefore, cannot be estimated.

9. NEW ACCOUNTING PRONOUNCEMENT

In August 2018, FASB issued Accounting Standards Update (“ASU”)No. 2018-13, Fair Value Measurement (Topic 820) Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. ASU2018-13 updates the disclosure requirements for fair value measurements by modifying or removing certain disclosures and adding certain new disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted.
