Yield refers to the income paid by the Fund over a given period. Yields for money market funds are usually for seven-day periods, as they are here, though they are expressed as annual percentage rates. Past performance is no guarantee of future results. Yield will vary and it's possible to lose money investing in the Fund. A portion of the Fund's expenses was reimbursed and/or waived. Absent such reimbursements and/or waivers the yield for the period ending September 30, 2017, the most recent period shown in the table, would have been 0.86% for Class I, 0.70% for Class II, 0.60% for Class III, 0.35% for Class IV, 0.81% for Select Class and 0.89% for Institutional Class.

Percentages shown as 0.0% may reflect amounts less than 0.05%.

Yield refers to the income paid by the Fund over a given period. Yields for money market funds are usually for seven-day periods, as they are here, though they are expressed as annual percentage rates. Past performance is no guarantee of future results. Yield will vary and it's possible to lose money investing in the Fund. A portion of the Fund's expenses was reimbursed and/or waived. Absent such reimbursements and/or waivers the yield for the period ending September 30, 2017, the most recent period shown in the table, would have been 0.87% for Class I, 0.71% for Class II, 0.61% for Class III, 0.36% for Class IV, 0.82% for Select Class and 0.90% for Institutional Class.

Percentages shown as 0.0% may reflect amounts less than 0.05%.

 (a) Yield represents either the annualized yield at the date of purchase, or the stated coupon rate, or, for floating and adjustable rate securities, the rate at period end.

 (b) Coupon rates for floating and adjustable rate securities reflect the rates in effect at period end.

 (c) Represents a forward settling transaction and therefore no collateral securities had been allocated as of period end. The agreement contemplated the delivery of U.S. Treasury Obligations as collateral on settlement date.

Yield refers to the income paid by the Fund over a given period. Yields for money market funds are usually for seven-day periods, as they are here, though they are expressed as annual percentage rates. Past performance is no guarantee of future results. Yield will vary and it's possible to lose money investing in the Fund. A portion of the Fund's expenses was reimbursed and/or waived. Absent such reimbursements and/or waivers the yield for the period ending September 30, 2017, the most recent period shown in the table, would have been 0.88% for Class I, 0.73% for Class II, 0.63% for Class III, 0.83% for Select Class and 0.91% for Institutional Class.

Percentages shown as 0.0% may reflect amounts less than 0.05%.

Yield refers to the income paid by the Fund over a given period. Yields for money market funds are usually for seven-day periods, as they are here, though they are expressed as annual percentage rates. Past performance is no guarantee of future results. Yield will vary and it's possible to lose money investing in the Fund. A portion of the Fund's expenses was reimbursed and/or waived. Absent such reimbursements and/or waivers the yield for the period ending September 30, 2017, the most recent period shown in the table, would have been 1.20% for Class I, 1.04% for Class II, 0.94% for Class III, 1.15% for Select Class and 1.23% for Institutional Class.

Legend

 (a) Yield represents either the annualized yield at the date of purchase, or the stated coupon rate, or, for floating and adjustable rate securities, the rate at period end.

 (b) Coupon rates for floating and adjustable rate securities reflect the rates in effect at period end.

 (c) Coupon is indexed to a floating interest rate which may be multiplied by a specified factor and/or subject to caps or floors.

 (d) Security exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers. At the end of the period, the value of these securities amounted to $1,065,593,000 or 4.7% of net assets.

 (e) The maturity amount is based on the rate at period end.

 (f) Represents a forward settling transaction and therefore no collateral securities had been allocated as of period end. The agreement contemplated the delivery of Corporate Obligations as collateral on settlement date.

Yield refers to the income paid by the Fund over a given period. Yields for money market funds are usually for seven-day periods, as they are here, though they are expressed as annual percentage rates. Past performance is no guarantee of future results. Yield will vary and it's possible to lose money investing in the Fund. A portion of the Fund's expenses was reimbursed and/or waived. Absent such reimbursements and/or waivers the yield for the period ending September 30, 2017, the most recent period shown in the table, would have been 1.14% for Class I, 0.99% for Class II, 0.89% for Class III, 0.58% for Class IV, 1.09% for Select Class and 1.17% for Institutional Class.

Percentages shown as 0.0% may reflect amounts less than 0.05%.

VRDN – VARIABLE RATE DEMAND NOTE (A debt instrument that is payable upon demand, either daily, weekly or monthly)

The date shown for securities represents the date when principal payments must be paid, taking into account any call options exercised by the issuer and any permissible maturity shortening features other than interest rate resets.

Legend

 (a) Yield represents either the annualized yield at the date of purchase, or the stated coupon rate, or, for floating and adjustable rate securities, the rate at period end.

 (b) Coupon rates for floating and adjustable rate securities reflect the rates in effect at period end.

 (c) Coupon is indexed to a floating interest rate which may be multiplied by a specified factor and/or subject to caps or floors.

 (d) The maturity amount is based on the rate at period end.

 (e) Represents a forward settling transaction and therefore no collateral securities had been allocated as of period end. The agreement contemplated the delivery of Corporate Obligations as collateral on settlement date.

Investment Valuation

All investments are categorized as Level 2 under the Fair Value Hierarchy. The inputs or methodology used for valuing securities may not be an indication of the risk associated with investing in those securities.

Yield will vary and it's possible to lose money investing in the Fund. A portion of the Fund's expenses was reimbursed and/or waived. Absent such reimbursements and/or waivers the yield for the period ending September 30, 2017, the most recent period shown in the table, would have been 1.14% for Class I, 0.99% for Class II, 0.89% for Class III, 1.09% for Select Class and 1.17% for Institutional Class.

Percentages shown as 0.0% may reflect amounts less than 0.05%.

Legend

 (a) Yield represents either the annualized yield at the date of purchase, or the stated coupon rate, or, for floating and adjustable rate securities, the rate at period end.

 (b) Coupon rates for floating and adjustable rate securities reflect the rates in effect at period end.

 (c) Coupon is indexed to a floating interest rate which may be multiplied by a specified factor and/or subject to caps or floors.

 (d) Security exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers. At the end of the period, the value of these securities amounted to $120,839,000 or 4.2% of net assets.

 (e) The maturity amount is based on the rate at period end.

 (f) Represents a forward settling transaction and therefore no collateral securities had been allocated as of period end. The agreement contemplated the delivery of Corporate Obligations as collateral on settlement date.

 ^A For the period June 2, 2016 (commencement of operations) to March 31, 2017.

 ^B Beginning October 3, 2016 the Fund began selling and redeeming class shares based upon the market-based value of the securities held rounded to the fourth decimal place; a "floating"net asset value.

 ^C Amount represents less than $.00005 per share.

 ^D Total returns for periods of less than one year are not annualized.

 ^E Total returns would have been lower if certain expenses had not been reduced during the applicable periods shown.

 ^F Expense ratios reflect operating expenses of the class. Expenses before reductions do not reflect amounts reimbursed or waived or reductions from expense offset arrangements and do not represent the amount paid by the class during periods when reimbursements, waivers or reductions occur. Expense ratios before reductions for start-up periods may not be representative of longer-term operating periods. Expenses net of fee waivers reflect expenses after reimbursement and waivers but prior to reductions from expense offset arrangements. Expenses net of all reductions represent the net expenses paid by the class.

 ^G Annualized

Yield refers to the income paid by the Fund over a given period. Yields for money market funds are usually for seven-day periods, as they are here, though they are expressed as annual percentage rates. Past performance is no guarantee of future results. Yield will vary and it's possible to lose money investing in the Fund. A portion of the Fund's expenses was reimbursed and/or waived. Absent such reimbursements and/or waivers the yield for the period ending September 30, 2017, the most recent period shown in the table, would have been 0.73% for Class I, 0.58% for Class II, 0.48% for Class III and 0.68% for Select Class.

Notes to Financial Statements (Unaudited)

For the period ended September 30, 2017
(Amounts in thousands except percentages)

1. Organization.

Treasury Only Portfolio, Treasury Portfolio, Government Portfolio, Money Market Portfolio, Prime Money Market Portfolio, Prime Reserves Portfolio and Tax-Exempt Portfolio (the Funds) are funds of Fidelity Colchester Street Trust (the Trust). Each Fund is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust. Each Fund offers Class I, Class II, Class III and Select Class shares. Prime Money Market Portfolio, Treasury Only Portfolio and Treasury Portfolio also offer Class IV and Institutional Class shares. Government Portfolio, Money Market Portfolio and Prime Reserves Portfolio also offer Institutional Class shares. Shares of Money Market Portfolio and Tax-Exempt Portfolio are only available for purchase by retail shareholders. All classes have equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Each Fund except for Tax-Exempt Portfolio offers conversion privileges from Class I to Institutional Class for eligible shareholders.

In accordance with amendments to Rule 2a-7 of the 1940 Act, Prime Money Market Portfolio and Prime Reserves Portfolio (the Institutional Funds) have each been designated an institutional money market fund, and the value of their shares are calculated to four decimal places that fluctuates based upon changes in the value of their investments.

Money Market Portfolio offered Class F shares during the period June 26, 2009 through May 20, 2016 and all outstanding shares were redeemed by May 20, 2016. All prior fiscal period dollar and share amounts for Money Market Portfolio Class F presented in the Notes to Financial Statements are for the period April 1, 2016 to May 20, 2016.

2. Investments in Fidelity Central Funds.

The Funds may invest in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Funds' Schedules of Investments list each of the Fidelity Central Funds held as of period end, if any, as an investment of each Fund, but do not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, each Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of the investment adviser. Annualized expenses of the Money Market Central Funds as of their most recent shareholder report date are less than .005%.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds are available on the SEC website or upon request.

3. Significant Accounting Policies.

Each Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services – Investments Companies. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Funds:

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has delegated the day to day responsibility for the valuation of each Institutional Fund's investments to the Fair Value Committee (the Committee) established by the Institutional Funds' investment adviser. In accordance with valuation policies and procedures approved by the Board, each Institutional Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with procedures adopted by the Board. Factors used in determining fair value vary by investment type and may include market or investment specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Institutional Funds' valuation policies and procedures and reports to the Board on the Committee's activities and fair value determinations. The Board monitors the appropriateness of the procedures used in valuing each Institutional Fund's investments and ratifies the fair value determinations of the Committee.

Each Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

• Level 1 – quoted prices in active markets for identical investments
• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
• Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value each Institutional Fund's investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. Municipal securities, U.S. government and government agency obligations, commercial paper, certificates of deposit and other short-term securities are valued by pricing vendors who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances. Short-term securities with remaining maturities of sixty days or less may be valued at amortized cost, which approximates fair value, and are categorized as Level 2 in the hierarchy.

For Treasury Only Portfolio, Treasury Portfolio, Government Portfolio, Money Market Portfolio and Tax-Exempt Portfolio as permitted by compliance with certain conditions under Rule 2a-7 of the 1940 Act, securities are valued at amortized cost, which approximates fair value. The amortized cost of an instrument is determined by valuing it at its original cost and thereafter amortizing any discount or premium from its face value at a constant rate until maturity.

Securities held by a money market fund are generally high quality and liquid; however, they are reflected as Level 2 because the inputs used to determine fair value are not quoted prices in an active market.

Investment Transactions and Income. Security transactions, including the Funds' investment activity in the Fidelity Central Funds, are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. The principal amount on inflation-indexed securities is periodically adjusted to the rate of inflation and interest is accrued based on the principal amount. The adjustments to principal due to inflation are reflected as increases or decreases to Interest in the accompanying Statement of Operations.

Class Allocations and Expenses. Investment income, realized and unrealized capital gains and losses, common expenses of each Fund, and certain fund-level expense reductions, if any, are allocated daily on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of each Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions may also differ by class. For the reporting period, the allocated portion of income and expenses to each class as a percent of its average net assets may vary due to the timing of recording these transactions in relation to fluctuating net assets of the classes. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Deferred Trustee Compensation. Under a Deferred Compensation Plan (the Plan) for Treasury Portfolio, Government Portfolio, Money Market Portfolio, Prime Money Market Portfolio and Tax-Exempt Portfolio, independent Trustees may elect to defer receipt of a portion of their annual compensation. Deferred amounts are invested in a cross-section of Fidelity funds, are marked-to-market and remain in the Fund until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting payable to the Trustees are included in the accompanying Statement of Assets and Liabilities.

Income Tax Information and Distributions to Shareholders. Each year, each Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. Each Fund files a U.S. federal tax return, in addition to state and local tax returns as required. Each Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.

Dividends are declared and recorded daily and paid monthly from net investment income. Distributions from realized gains, if any, are declared and recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.

Book-tax differences are primarily due to deferred trustees compensation, capital loss carryforwards and losses deferred due to wash sales.

The Tax-Exempt Portfolio purchases municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the IRS will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued.

As of period end, the cost and unrealized appreciation (depreciation) in securities for federal income tax purposes were as follows for each Fund:

	Tax cost	Gross unrealized appreciation	Gross unrealized depreciation	Net unrealized appreciation (depreciation)
Treasury Only Portfolio	$13,207,920	$–	$–	$–
Treasury Portfolio	24,722,958	–	–	–
Government Portfolio	98,073,269	–	–	–
Money Market Portfolio	22,586,047	–	–	–
Prime Money Market Portfolio	13,286,405	1,242	(120)	1,122
Prime Reserves Portfolio	2,936,118	168	(45)	123
Tax-Exempt Portfolio	3,084,040	–	–	–

Capital loss carryforwards are only available to offset future capital gains of the Funds to the extent provided by regulations and may be limited. Under the Regulated Investment Company Modernization Act of 2010 (the Act), the Funds are permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period and such capital losses are required to be used prior to any losses that expire. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of prior fiscal period end and is subject to adjustment.

	Fiscal year of expiration
	2019
Government Portfolio	$(118)

	No expiration Short-term
Tax-Exempt Portfolio	$(15)

Repurchase Agreements. Pursuant to an Exemptive Order issued by the Securities and Exchange Commission (the SEC), the Funds along with other registered investment companies having management contracts with Fidelity Management and Research Company (FMR), an affiliate of SelectCo, or other affiliated entities of FMR, are permitted to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Funds may also invest directly with institutions in repurchase agreements. For Treasury Only Portfolio, Treasury Portfolio and Government Portfolio, repurchase agreements may be collateralized by cash or government securities. For Prime Money Market Portfolio, Money Market Portfolio, Prime Reserves Portfolio and Tax-Exempt Portfolio, repurchase agreements may be collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. Each applicable Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

Reverse Repurchase Agreements. To enhance their yield, the Funds may enter into reverse repurchase transactions under master repurchase agreements whereby the Fund sells securities to a counterparty in return for cash and agrees to repurchase those securities at a future date and agreed upon price. During the period that reverse repurchase transactions are outstanding, each applicable fund identifies the securities as pledged in its records with an initial value at least equal to its principal obligation under the agreement. The cash proceeds received by the Funds may be invested in other securities. To the extent cash proceeds received from the counterparty exceed the value of the securities sold, the counterparty may request additional collateral from the Fund. If the counterparty defaults on its obligation, because of insolvency or other reasons, the Fund could experience delays and costs in recovering the securities sold. Information regarding securities sold under a reverse repurchase agreement, if any, is included at the end of each applicable Fund's Schedule of Investments and the cash proceeds are recorded as a liability in each applicable fund's accompanying Statement of Assets and Liabilities. The Fund continues to receive interest and dividend payments on the securities sold during the term of the reverse repurchase agreement. At period end, there were no reverse repurchase agreements outstanding.

Restricted Securities. The Funds may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of each applicable Fund's Schedule of Investments.

4. Fees and Other Transactions with Affiliates.

This program provides an alternative credit facility allowing the funds to borrow from, or lend money to, other participating affiliated funds. At period end, there were no interfund loans outstanding. Each applicable fund's activity in this program during the period for which loans were outstanding was as follows:

		Average Loan Balance	Weighted Average Interest Rate
Money Market Portfolio	Lender	16,618	1.14%
Prime Reserves Portfolio	Lender	15,452	1.19%

Interfund Trades. The Funds may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act.

Other. During the period, the investment adviser reimbursed the Funds for certain losses as follows:

	Amount
Treasury Portfolio	$1
Money Market Portfolio	9
Prime Money Market Portfolio	7
Prime Reserves Porfolio	1

5. Expense Reductions.

The Funds' organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Funds. In the normal course of business, the Funds may also enter into contracts that provide general indemnifications. The Funds' maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Funds. The risk of material loss from such claims is considered remote.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees, distribution and/or service (12b-1) 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 period and held for the entire period (April 1, 2017 to September 30, 2017).

Actual Expenses

The first line of the accompanying table for each Class of each fund 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 $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a Class of the fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, each Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each Class of each fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' 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. In addition, each Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second 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.

Board Approval of Investment Advisory Contracts and Management Fees

FIMM Funds: Government Portfolio / Money Market Portfolio / Prime Money Market Portfolio / Prime Reserves Portfolio / Tax-Exempt Portfolio / Treasury Portfolio / Treasury Only Portfolio

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract with Fidelity Management & Research Company (FMR) and the sub-advisory agreements (together, the Advisory Contracts) for each fund. FMR and the sub-advisers are referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of each fund's Advisory Contracts, including the services and support provided to each fund and its shareholders. The Board has established four standing committees (Committees) — Operations, Audit, Fair Valuation, and Governance and Nominating — each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Operations Committee, of which all of the Independent Trustees are members, meets regularly throughout the year and considers, among other matters, information specifically related to the annual consideration of the renewal of each fund's Advisory Contracts. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of each fund's Advisory Contracts. The Board also meets as needed to review matters specifically related to the Board's annual consideration of the renewal of the Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through ad hoc joint committees to discuss certain matters relevant to all of the Fidelity funds.

At its September 2017 meeting, the Board unanimously determined to renew each fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services to be provided to each fund and its shareholders (including the investment performance of each fund); (ii) the competitiveness of each fund's management fee and total expense ratio relative to peer funds; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its relationships with each fund; and (iv) the extent to which, if any, economies of scale exist and would be realized as each fund grows, and whether any economies of scale are appropriately shared with fund shareholders.

In considering whether to renew the Advisory Contracts for each fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts was in the best interests of each fund and its shareholders and that the compensation payable under the Advisory Contracts was fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, was aware that shareholders of each fund have a broad range of investment choices available to them, including a wide choice among funds offered by Fidelity's competitors, and that each fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in that fund, which is part of the Fidelity family of funds.

Nature, Extent, and Quality of Services Provided.  The Board considered Fidelity's staffing as it relates to the funds, including the backgrounds of investment personnel of Fidelity, and also considered the funds' investment objectives, strategies, and related investment philosophies. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the investment personnel compensation program and whether this structure provides appropriate incentives to act in the best interests of each fund. Additionally, the Board considered the portfolio managers' investments, if any, in the funds that they manage.Resources Dedicated to Investment Management and Support Services.  The Board reviewed the general qualifications and capabilities of Fidelity's investment staff, including its size, education, experience, and resources, as well as Fidelity's approach to recruiting, managing, and compensating investment personnel. The Board noted that Fidelity has continued to increase the resources devoted to non-U.S. offices, including expansion of Fidelity's global investment organization. The Board also noted that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct sophisticated quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. Further, the Board considered that Fidelity's investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered Fidelity's trading, risk management, compliance, and technology and operations capabilities and resources, which are integral parts of the investment management process.Shareholder and Administrative Services.  The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency and pricing and bookkeeping services for each fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted to, and the record of compliance with, each fund's compliance policies and procedures.The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value or convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information through telephone representatives and over the Internet, investor education materials and asset allocation tools, and the expanded availability of Fidelity Investor Centers.Investment in a Large Fund Family.  The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including: (i) continuing to dedicate additional resources to Fidelity's investment research process, which includes meetings with management of issuers in which the funds invest, and to the support of the senior management team that oversees asset management; (ii) continuing efforts to enhance Fidelity's global research capabilities; (iii) launching new funds and making other enhancements to meet client needs; (iv) launching new share classes of existing funds; (v) eliminating purchase minimums and broadening eligibility requirements for certain lower-priced share classes; (vi) reducing management fees and total expenses for certain growth equity funds and index funds; (vii) lowering expense caps for certain existing funds and classes to reduce expenses borne by shareholders; (viii) eliminating short-term redemption fees for certain funds; (ix) introducing a new pricing structure for certain funds of funds that is expected to reduce overall expenses paid by shareholders; (x) rationalizing product lines and gaining increased efficiencies through proposals for fund mergers and share class consolidations; (xi) continuing to develop, acquire and implement systems and technology to improve services to the funds and shareholders, strengthen information security, and increase efficiency; and (xii) implementing enhancements to further strengthen Fidelity's product line to increase investors' probability of success in achieving their investment goals, including retirement income goals.Investment Performance.  The Board considered whether each fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions and its performance history. As Prime Reserves Portfolio recently commenced operations, the Board did not believe that it was appropriate to assign significant weight to its limited investment performance. The Board noted that there were portfolio management changes for Government Portfolio, Prime Money Market Portfolio, Prime Reserves Portfolio, Tax-Exempt Portfolio, Treasury Portfolio, and Treasury Only Portfolio in March 2017.The Board took into account discussions with representatives of the Investment Advisers about fund investment performance that occur at Board meetings throughout the year. In this regard the Board noted that as part of regularly scheduled fund reviews and other reports to the Board on fund performance, the Board considers annualized return information for each fund for different time periods, measured against a peer group of funds with similar objectives ("peer group").In addition to reviewing absolute and relative fund performance, the Independent Trustees periodically consider the appropriateness of fund performance metrics in evaluating the results achieved. In general, the Independent Trustees believe that fund performance should be evaluated based on gross performance (before fees and expenses but after transaction costs) compared to the gross performance of appropriate peer groups, over appropriate time periods that may include full market cycles, taking into account relevant factors including the following: general market conditions; expectations for interest rate levels and credit conditions; issuer-specific information including credit quality; the fund's market value NAV over time and its resilience under various stressed conditions; and fund cash flows and other factors.The Board recognizes that in interest rate environments where many competitors waive fees to maintain a minimum yield, relative money market fund performance on a net basis (after fees and expenses) may not be particularly meaningful due to miniscule performance differences among competitor funds. Depending on the circumstances, the Independent Trustees may be satisfied with a fund's performance notwithstanding that it lags its peer group for certain periods.The Independent Trustees recognize that shareholders evaluate performance on a net basis over their own holding periods, for which one-, three-, and five-year periods are often used as a proxy. For this reason, the performance information reviewed by the Board also included net cumulative calendar year total return information for each fund (except Prime Reserves Portfolio) and an appropriate peer group for the most recent one-, three-, and five-year periods.Based on its review, the Board concluded that the nature, extent, and quality of services provided to each fund under the Advisory Contracts should continue to benefit the shareholders of each fund.Competitiveness of Management Fee and Total Expense Ratio.  The Board considered each fund's management fee and total expense ratio compared to "mapped groups" of competitive funds and classes created for the purpose of facilitating the Trustees' competitive analysis of management fees and total expenses. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable investment mandates. Combining Lipper investment objective categories aids the Board's management fee and total expense ratio comparisons by broadening the competitive group used for comparison.Management Fee.  The Board considered two proprietary management fee comparisons for the 12-month (or shorter) periods shown in basis points (BP) in the charts below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group" and, for the reasons explained above, is broader than the Lipper peer group used by the Board for performance comparisons. The Total Mapped Group comparison focuses on a fund's standing in terms of gross management fees before expense reimbursements or caps relative to the total universe of funds with comparable investment mandates, regardless of whether their management fee structures also are comparable. Funds with comparable investment mandates offer exposure to similar types of securities. Funds with comparable management fee structures have similar management fee contractual arrangements (e.g., flat rate charged for advisory services, all-inclusive fee rate, etc.). "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than a fund's. For example, a hypothetical TMG % of 20% would mean that 80% of the funds in the Total Mapped Group had higher, and 20% had lower, management fees than a fund. The funds' actual TMG %s and the number of funds in the Total Mapped Group are in the charts below. The "Asset-Size Peer Group" (ASPG) comparison focuses on a fund's standing relative to a subset of non-Fidelity funds within the Total Mapped Group that are similar in size and management fee structure. For example, if a fund is in the first quartile of the ASPG, the fund's management fee ranks in the least expensive or lowest 25% of funds in the ASPG. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee structures, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which a fund's management fee rate ranked, is also included in the charts and considered by the Board.

The Board noted that each fund's management fee rate ranked below the median of its Total Mapped Group and below the median of its ASPG for 2016. For each of Money Market Portfolio and Tax-Exempt Portfolio, the Board noted that the comparisons for 2015 reflect a new Total Mapped Group in light of changes to the fund's shareholder eligibility.The Board noted that it and the boards of other Fidelity funds formed an ad hoc Committee on Group Fee, which meets periodically, to conduct an in-depth review of the "group fee" component of the management fee of funds with such management fee structures. The Committee's focus included the mechanics of the group fee, the competitive landscape of group fee structures, Fidelity funds with no group fee component (such as the funds) and investment products not included in group fee assets. The Board also considered that, for funds subject to the group fee, FMR agreed to voluntarily waive fees over a specified period of time in amounts designed to account for assets converted from certain funds to certain collective investment trusts.Based on its review, the Board concluded that each fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.Total Expense Ratio.  In its review of the total expense ratio of each class of each fund, the Board considered the fund's management fee rate as well as other fund or class expenses, as applicable, such as transfer agent fees, pricing and bookkeeping fees, fund-paid 12b-1 fees, and custodial, legal, and audit fees. The Board also noted that Fidelity may agree to waive fees and expenses from time to time, and the extent to which, if any, it has done so for each fund. As part of its review, the Board also considered the current and historical total expense ratios of each class of each fund compared to competitive fund median expenses. Each class of each fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure.The Board noted that the total expense ratio of each of Class I, Class II, and Select Class of Tax-Exempt Portfolio ranked below the competitive median for 2016 and the total expense ratio of Class III ranked above the competitive median for 2016.The Board noted that the total expense ratio of each of Class I and Institutional Class of Money Market Portfolio ranked below the competitive median for 2016, the total expense ratio of Select Class ranked equal to the competitive median for 2016, and the total expense ratio of each of Class II and Class III ranked above the competitive median for 2016.The Board noted that the total expense ratio of each of Class I and Institutional Class of each of Government Portfolio and Prime Reserves Portfolio ranked below the competitive median for 2016 and the total expense ratio of each of Class II, Class III, and Select Class ranked above the competitive median for 2016.The Board noted that the total expense ratio of each of Class I and Institutional Class of each of Prime Money Market Portfolio, Treasury Portfolio, and Treasury Only Portfolio ranked below the competitive median for 2016 and the total expense ratio of each of Class II, Class III, Class IV, and Select Class ranked above the competitive median for 2016.The Board considered that, in general, various factors can affect total expense ratios. The Board noted that each fund offers multiple classes, each of which has a different 12b-1 fee structure, and that the multiple structures are intended to offer a range of pricing options for the intermediary market. The Board also noted that the total expense ratios of the classes of each fund vary primarily by the level of their 12b-1 fees, although differences in transfer agent fees may also cause expenses to vary from class to class.The Board considered that, for certain classes, Fidelity has been voluntarily waiving part or all of the 12b-1 fees, transfer agent fees, and/or management fees to maintain a minimum yield. The total expense ratio of the classes noted above ranked above the competitive median for 2016 because the advisers of many competitor funds waived fees or reimbursed expenses to a greater extent than Fidelity in order to maintain a minimum yield, which caused the expense medians of such competitor funds to be lower than they would otherwise be (Class I, Class II, Institutional Class, and Select Class) and due to the class's 12b-1 fee (Class III and Class IV). Excluding fee waivers (and, for Class III and Class IV, 12b-1 fees), the total expense ratio of each class of each fund ranked below the median.The Board further considered that FMR has contractually agreed to reimburse each class of each fund to the extent that total operating expenses (excluding interest, certain taxes, certain securities lending costs, brokerage commissions, fees and expenses of the Independent Trustees, proxy and shareholder meeting expenses, extraordinary expenses, and acquired fund fees and expenses, if any), as a percentage of their respective average net assets, exceed the following rates: Class I: 0.18%; Class II: 0.33%; Class III: 0.43%; Class IV: 0.68%; Institutional Class: 0.14%; and Select Class: 0.23%, each through May 31, 2018.Fees Charged to Other Fidelity Clients.  The Board also considered Fidelity fee structures and other information with respect to clients of Fidelity, such as other funds advised or subadvised by Fidelity, pension plan clients, and other institutional clients with similar mandates. The Board noted that an ad hoc joint committee created by it and the boards of other Fidelity funds periodically reviews and compares Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds, including the differences in services provided, fees charged, and costs incurred, as well as competition in their respective marketplaces.Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that, although some classes were above the median of the universe presented for comparison, the total expense ratio of each class of each fund was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.Costs of the Services and Profitability.  The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing each fund and servicing each fund's shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.On an annual basis, Fidelity presents to the Board information about the profitability of its relationships with each fund. Fidelity calculates profitability information for each fund, as well as aggregate profitability information for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.PricewaterhouseCoopers LLP (PwC), independent registered public accounting firm and auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. PwC's engagement includes the review and assessment of the methodologies used by Fidelity in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures in respect of the mathematical accuracy of the fund profitability information and its conformity to established allocation methodologies. After considering PwC's reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.The Board also reviewed Fidelity's non-fund businesses and potential fall-out benefits related to the mutual fund business as well as cases where Fidelity's affiliates may benefit from or be related to the funds' business.The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of each fund and was satisfied that the profitability was not excessive.Economies of Scale.  The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including each fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which each fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board also noted that a committee (the Economies of Scale Committee) created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.Additional Information Requested by the Board.  In order to develop fully the factual basis for consideration of the Fidelity funds' advisory contracts, the Board requested and received additional information on certain topics, including: (i) Fidelity's fund profitability methodology, profitability trends for certain funds, and the impact of certain factors on fund profitability results; (ii) portfolio manager changes that have occurred during the past year and the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (iii) Fidelity's compensation structure for portfolio managers, research analysts, and other key personnel, including its effects on fund profitability, the rationale for the compensation structure, and the extent to which current market conditions have affected retention and recruitment; (iv) the arrangements with and compensation paid to certain fund sub-advisers on behalf of the Fidelity funds; (v) the terms of Fidelity's contractual and voluntary expense cap and waiver arrangements with the funds; (vi) the methodology with respect to competitive fund data and peer group classifications; (vii) Fidelity's transfer agent fee, expense, and service structures for different funds and classes relative to competitive trends, and the impact of the increased use of omnibus accounts; (viii) Fidelity's long-term expectations for its offerings in the workplace investing channel; (ix) new developments in the retail and institutional marketplaces and the competitive positioning of the funds relative to other investment products and services; (x) the approach to considering "fall-out" benefits; (xi) the impact of money market reform on Fidelity's money market funds, including with respect to costs and profitability; (xii) the funds' share class structures and distribution channels, including the impact of the Department of Labor's new fiduciary rule on the funds' distribution arrangements; and (xiii) explanations regarding the relative total expense ratios of certain funds and classes, total expense competitive trends and methodologies for total expense competitive comparisons, and actions that might be taken by Fidelity to reduce total expense ratios for certain classes. In addition, the Board considered its discussions with Fidelity throughout the year regarding enhanced information security initiatives and the funds' fair valuation policies.Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board concluded that the advisory fee structures are fair and reasonable, and that each fund's Advisory Contracts should be renewed.
