Expense Examples (unaudited)

EXAMPLE

As a shareholder of each Portfolio, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees and other Portfolio expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolios 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 (January 1, 2019 to June 30, 2019).

ACTUAL EXPENSES

The first 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 first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below for each Portfolio provides information about hypothetical account values and hypothetical expenses based on each Portfolio’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Portfolio’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 a Portfolio 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 or separate account charges. 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. In addition, if these transactional costs or separate account charges were included, your costs would have been higher.

As anon-diversified portfolio, the Portfolio may hold fewer securities because of its focused investment strategy. Holding fewer securities increases the risk that the value of the Portfolio could go down because of the poor performance of a single investment.

The Portfolio may invest a relatively high percentage of its assets in a particular sector. The Portfolio will have greater exposure to the risks associated with that sector and its performance will be tied more closely to the performance of the sector.

The Portfolio may invest in derivative instruments, such as futures and, to a lesser extent, swap agreements, to help achieve full replication. Use of these instruments may involve certain costs and imposes certain risks such as liquidity risk, market risk, credit risk, management risk and the risk of mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

Use of these instruments may involve certain costs and imposes certain risks such as liquidity risk, market risk, credit risk, management risk and the risk of mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

Sector Allocation is subject to change.

The Portfolio invests with an emphasis on larger capitalization stocks with a strong track record of paying dividends or that are believed to be undervalued. The Portfolio may underperform similar funds that invest without an emphasis on dividend-paying stocks. Dividend-paying stocks may not participate in a broad market advance to the same degree as other stocks.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend.

The Portfolio may invest a relatively high percentage of its assets in a particular sector. The Portfolio will have greater exposure to the risks associated with that sector and its performance will be tied more closely to the performance of the sector.

The Portfolio is not sponsored, endorsed, sold or promoted by Standard & Poor’s, and Standard & Poor’s makes no representation regarding the advisability of investing in the Portfolio.

Investing in small andmedium-sized companies involves a greater degree of risk than investing in large company stocks.

The Portfolio may invest in derivative instruments such as futures and, to a lesser extent, swap agreements to help achieve full replication. Use of these instruments may involve certain costs and imposes certain risks such as liquidity risk, market risk, credit risk, management risk and the risk of mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

Investing in small andmedium-sized companies involves a greater degree of risk than investing in large company stocks. The value of securities acquired in an IPO may rise or fall more rapidly than investments in more established issuers.

The Portfolio may invest in derivative instruments for cash management purposes or to hedge foreign currency exposure. Use of these instruments may involve certain costs and imposes certain risks such as liquidity risk, market risk, credit risk, management risk and the risk of mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

For the previous fiscal year’s federal income tax information, please refer to the Notes to the Financial Statements section in the Portfolio’s most recent annual report.

Sector Allocation is subject to change.

Stocks of smaller or newer companies, such as those held in this Portfolio, are more likely to realize more substantial growth as well as suffer more significant losses than larger or more established issuers. Investments in such companies can be both more volatile and more speculative. Investing in small company stocks involves a greater degree of risk than investing in medium or large company stocks.

The Portfolio may invest in exchange-traded funds (“ETFs”) for cash management purposes. Investing in ETFs may expose the Portfolio to greater risk of loss and price fluctuation than investing directly in an equity security. The market prices of ETFs may trade at a premium or discount to their net asset value and may be subject to trading halts by the applicable exchange, which may negatively impact the Portfolio.

The Portfolio may invest a relatively high percentage of its assets in a particular sector. The Portfolio will have greater exposure to the risks associated with that sector and its performance will be tied more closely to the performance of the sector.

“Standard & Poor’s^®”, “S&P^®”, “S&P SmallCap 600” and “Standard & Poor’s SmallCap 600” are trademarks of The McGraw-Hill Companies, Inc. and have been licensed for use by Northwestern Mutual Life Insurance Company. The Portfolio is not sponsored, endorsed, sold or promoted by Standard & Poor’s, and Standard & Poor’s makes no representation regarding the advisability of investing in the Portfolio.

Stocks of smaller or newer companies, such as those held in this Portfolio, are more likely to realize more substantial growth as well as suffer more significant losses than larger or more established issuers. Investments in such companies can be both more volatile and more speculative. Investing in small company stocks involves a greater degree of risk than investing in medium or large company stocks.

The Portfolio may invest in exchange-traded funds and derivative instruments such as swap agreements and, to a lesser extent, futures contracts, for cash management purposes and to help achieve full replication. Use of these instruments may involve certain costs and imposes certain risks such as liquidity risk, market risk, credit risk, management risk and the risk of mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

   Sector Allocation is subject to change.

Stocks of smaller or newer companies, such as those held in this Portfolio, are more likely to realize more substantial growth as well as suffer more significant losses than larger or more established issuers. Investments in such companies can be both more volatile and more speculative. Investing in small company stocks involves a greater degree of risk than investing in medium or large company stocks.

The Portfolio may invest a portion of its assets in other investment companies, includingopen-end andclosed-end funds, exchange-traded funds (“ETFs”), and business development companies (“BDCs”), and will bear its pro rata portion of such expenses. The market prices of ETFs,closed-end funds and BDCs may trade at a premium or discount to their net asset values and may be subject to trading halts by the applicable exchange, which may negatively impact the Portfolio. BDCs in particular may be less liquid and more adversely affected by poor economic or market conditions.

The Portfolio may invest a relatively high percentage of its assets in a particular sector. The Portfolio will have greater exposure to the risks associated with that sector and its performance will be tied more closely to the performance of the sector.

  Sector Allocation is subject to change.

Investors should be aware of the risks of investments in foreign securities, particularly investments in securities of companies in developing nations. These include the the risks of currency fluctuation, of political and economic instability and of less well-developed government supervision and regulation of business and industry practices, as well as differences in accounting standards.

Investments in the securities of companies in developing nations impose risks different from, and greater than, risks of investing in developed countries.

The Portfolio may invest a relatively large percentage of its assets in issuers located in a single country, a small number of countries, or a particular geographic region. The Portfolio’s performance may be more volatile than that of a more geographically diversified fund, and may be tied more closely to the performance of a single country or region.

Investors should be aware of the risks of investments in foreign securities, particularly investments in securities of companies in developing nations. These include the risks of currency fluctuation, of political and economic instability and of less well-developed government supervision and regulation of business and industry practices, as well as differences in accounting standards.

Investments in the securities of companies in developing nations impose risks different from, and greater than, risks of investing in developed countries.

The Portfolio may invest a relatively large percentage of its assets in issuers located in a single country, a small number of countries, or a particular geographic region. The Portfolio’s performance may be more volatile than that of a more geographically diversified fund, and may be tied more closely to the performance of a single country or region.

The Portfolio may invest a relatively high percentage of its assets in a particular sector. The Portfolio will have greater exposure to the risks associated with that sector and its performance will be tied more closely to the performance of that sector.

Government Money Market Portfolio (unaudited)

Not all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some obligations are backed only by the credit of the issuing agency or instrumentality, and in some cases there may be some risk of default by the issuer. Any guarantee by the U.S. government or its agencies or instrumentalities of a security held by the Portfolio does not apply to the market value of such security or to shares of the Portfolio itself.

If the other party to a repurchase agreement defaults on its obligation under the agreement, the Portfolio may suffer delays and incur costs or lose money in exercising its rights under the agreement. These risks may be heightened if the other party is located outside the U.S. If the seller fails to repurchase the security and the market value of the security declines, the Portfolio may lose money.

You could lose money investing in the Government Money Market Portfolio. Although the Portfolio seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Portfolio is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Portfolio’s sponsor has no legal obligation to provide financial support to the Portfolio, and you should not expect that the sponsor will provide financial support to the Portfolio at any time.

Short-Term Bond Portfolio (unaudited)

Sector Allocation 6/30/19

Sector	% of Net Assets
Corporate Bonds	50.6%
Structured Products	33.8%
Governments	14.9%
Short-Term Investments & Other Net Assets	0.6%
Municipal Bonds	0.1%

Sector Allocation is subject to change.

Consistent with the Portfolio’s stated parameters, no more than 20% of the Portfolio is invested in foreign securities, and no more than 10% is invested in high yield securities.

Return of principal is not guaranteed. Bond funds have the same interest rate, inflation and credit risks that are associated with the underlying bonds owned by the Portfolio. When interest rates rise, bond prices fall. With a fixed income fund, when interest rates rise, the value of the fund’s existing bonds drops, which could negatively affect overall fund performance. A portion of the Portfolio’s asses may be invested in lower quality debt securities which may present a significant risk for loss of principal and interest. High yield bonds generally have greater price swings and higher default risks than investment grade bonds.

Investing in bonds issued by foreign corporations and governments carries additional risk, including foreign currency risk, and may increase the volatility of the Portfolio’s performance.

The Portfolio may invest in derivative instruments to adjust the Portfolio’s duration and yield curve exposure, to hedge foreign currency exposure or for any other permissible purpose keeping with its investment objective. Use of these instruments may involve certain costs and imposes certain risks such as liquidity risk, market risk, credit risk, management risk and the risk of mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates over a short period of time could cause significant losses in the market value of the Portfolio’s fixed income investments.

Select Bond Portfolio (unaudited)

    Sector Allocation 6/30/19

Sector	% of Net Assets
Structured Products	50.9%
Governments	29.5%
Corporate Bonds	24.1%
Short-Term Investments & Other Net Assets	2.2%
80	0.7%
Municipal Bonds	0.5%

Sector Allocation is subject to change.

Consistent with the Portfolio’s stated parameters, no more than 20% of the Portfolio is invested in foreign securities, and no more than 10% is invested in high yield securities.

Return of principal is not guaranteed. Bond funds have the same interest rate, inflation and credit risks that are associated with the underlying bonds owned by the Portfolio. When interest rates rise, bond prices fall. With a fixed income fund, when interest rates rise, the value of the fund’s existing bonds drops, which could negatively affect overall fund performance. A portion of the Portfolio’s asses may be invested in lower quality debt securities which may present a significant risk for loss of principal and interest. High yield bonds generally have greater price swings and higher default risks than investment grade bonds.

Investing in bonds issued by foreign corporations and governments carries additional risk, including foreign currency risk, and may increase the volatility of the Portfolio’s performance.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates over a short period of time could cause significant losses in the market value of the Portfolio’s fixed income investments.

The Portfolio may engage in active and frequent trading of portfolio securities to achieve its investment objectives. Active and frequent trading may cause higher brokerage expenses and other transaction costs, which may adversely affect performance.

Long-Term U.S. Government Bond Portfolio (unaudited)

    Sector Allocation 6/30/19

Sector	% of Net Assets
Governments	103.8%
Structured Products	20.0%
Corporate Bonds	0.7%
Short-Term Investments & Other Net Assets	-28.9%

Sector Allocation is subject to change.

Consistent with the Portfolio’s stated parameters, no more than 10% of the Portfolio is invested in securities rated A by Moody’s or S&P and no more than 25% of the Portfolio is invested in securities rated Aa by Moody’s or AA by S&P.

Return of principal is not guaranteed. Bond funds have the same interest rate, inflation and credit risks that are associated with the underlying bonds owned by the Portfolio. When interest rates rise, bond prices fall. With a fixed income fund, when interest rates rise, the value of the fund’s existing bonds drops, which could negatively affect overall fund performance.

The Portfolio may invest in securities that are issued or guaranteed by the U.S. Government or its agencies, and in derivatives designed to replicate such securities. This guarantee provides for the timely repayment of the principal and interest as applicable under the terms of the instrument, if it is held to maturity, and does not apply to derivatives securities held by the Portfolio. A guarantee by the U.S. Government or its agencies does not eliminate market risk.

The Portfolio may also use derivative instruments for hedging or other purposes as part of its investment strategy. Use of these instruments may involve certain costs and risks such as liquidity risk, interest rate risk, market risk, credit risk, management risk and the risk that the Portfolio could not close out a position when it would be most advantageous to do so. The potential leverage created by use of derivatives may cause the Portfolio to be more sensitive to interest rate movements and thus more volatile than other long-term U.S. Government bond funds that do not use derivatives. Portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates over a short period of time could cause significant losses in the market value of the Portfolio’s fixed income investments.

The Portfolio may engage in active and frequent trading of portfolio securities to achieve its investment objectives. Active and frequent trading may cause higher brokerage expenses and other transaction costs, which may adversely affect performance.

Inflation Protection Portfolio (unaudited)

    Sector Allocation 6/30/19

Sector	% of Net Assets
Governments	54.4%
Structured Products	23.4%
Corporate Bonds	13.4%
Short-Term Investments & Other Net Assets	8.3%
Municipal Bonds	0.5%

Sector Allocation is subject to change.

Consistent with the Portfolio’s stated parameters, no more than 20% of the Portfolio is invested in foreign securities.

Return of principal is not guaranteed. Bond funds have the same interest rate, inflation and credit risks that are associated with the underlying bonds owned by the Portfolio. When interest rates rise, bond prices fall. With a fixed income fund, when interest rates rise, the value of the fund’s existing bonds drops, which could negatively affect overall fund performance.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates over a short period of time could cause significant losses in the market value of the Portfolio’s fixed income investments.

Investing in bonds issued by foreign corporations and governments carries additional risk, including foreign currency risk, and may increase the volatility of the Portfolio’s performance.

As a non-diversified portfolio, the Portfolio may hold fewer securities because of its focused investment strategy. Holding fewer securities increases the risk that the value of the Portfolio could go down because of the poor performance of a single investment.

This Portfolio invests over 50% of its assets in inflation-linked bonds. Inflation-linked bonds issued by the U.S. Government, known as TIPs, are fixed income securities whose principal value is periodically adjusted according to the rate of inflation. Neither the current market value of the inflation-linked bonds nor the share value of the fund that invests in them is guaranteed, and either or both may fluctuate. Those portions of the Portfolio which are not invested in inflation linked securities will not be automatically protected from inflation. The Portfolio may use derivative instruments for hedging or other purposes as part of its investment strategy. Use of these instruments may involve certain costs and risks such as liquidity risk, interest rate risk, market risk, credit risk, management risk and the risk that the Portfolio could not close out a position when it would be most advantageous to do so. Portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

Sector Allocation is subject to change.

The Portfolio invests in lower quality securities, which may represent a significant risk for loss of principal and interest. Bonds and other debt obligations are affected by changes in interest rates, inflation risk and the creditworthiness of their issuers. High yield bonds generally have greater price swings and higher default risks than investment grade bonds. Return of principal is not guaranteed. When interest rates rise, bond prices fall. With a fixed income fund, when interest rates rise, the value of the fund’s existing bonds drops, which could negatively affect overall fund performance.

Investing in bonds issued by foreign corporations and governments carries additional risk, including foreign currency risk, and may increase the volatility of the Portfolio’s performance.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates over a short period of time could cause significant losses in the market value of the Portfolio’s fixed income investments.

Multi-Sector Bond Portfolio (unaudited)

     Sector Allocation 6/30/19

Sector	% of Net Assets
Corporate Bonds	50.7%
Governments	19.5%
Structured Products	13.3%
Short-Term Investments & Other Net Assets	12.8%
Bank Loan Obligations	2.6%
Municipal Bonds	1.1%

  Sector Allocation is subject to change.

The Portfolio invests in lower-quality securities, which may present a significant risk for loss of principal and interest. Bonds and other debt obligations are affected by changes in interest rates, inflation risk and the creditworthiness of their issuers. High yield bonds generally have greater price swings and higher default risks than investment grade bonds. Return of principal is not guaranteed. When interest rates rise, bond prices fall. With a fixed income fund, when interest rates rise, the value of the fund’s existing bonds drops, which could negatively affect overall fund performance.

Investing in bonds issued by foreign corporations and governments carries additional risk, including foreign currency risk, and may increase the volatility of the Portfolio’s performance.

The Portfolio may use derivative instruments for hedging purposes or as alternatives to direct investments. Use of these instruments may involve certain costs and risks such as liquidity risk, interest rate risk, market risk, credit risk, management risk and the risk of mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those instruments.

The Portfolio may invest a portion of its assets in fixed- and floating-rate loans, including senior loans, through loan participations and assignments. Investing in loans may expose the Portfolio to additional risks, including credit risk, interest rate risk, liquidity risk, call risk, settlement risk, and risks associated with being a lender.

The Portfolio may also invest in municipal securities, which may be more sensitive to certain adverse conditions than other fixed income securities, may be or become illiquid, and may have yields which move differently and adversely compared to the yields of the overall debt securities markets.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates over a short period of time could cause significant losses in the market value of the Portfolio’s fixed income investments.

     Sector Allocation 6/30/19

Sector	% of Net Assets
Fixed Income	46.8%
Domestic Equity	36.0%
Foreign Equity	10.3%
Short-Term Investments & Other Net Assets	6.9%

     Sector Allocation is subject to change.

Investors should be aware of the risks of investments in foreign securities, particularly investments in securities of companies in developing nations. These include the risks of currency fluctuation, of political and economic instability and of less well-developed government supervision and regulation of business and industry practices, as well as differences in accounting standards. Small cap stocks also may carry additional risk. Smaller or newer issuers are more likely to realized more substantial growth as well as suffer more significant losses than larger or more established issuers. Investments in such companies can be both volatile and more speculative. Bonds and other debt obligations are affected by changes in interest rates, inflation and the creditworthiness of their issuers. High yield bonds generally have greater price swings and higher default risks than investment grade bonds.

The Portfolio may obtain its exposure to domestic and foreign equity securities by investing in other Series Fund portfolios (Underlying Portfolios). Each of the Underlying Portfolios has its own investment risks, and the Portfolio is indirectly exposed to all the risks of the Underlying Portfolios in which it invests, including that risk that an Underlying Portfolio will not perform as expected. To the extent that the Portfolio invests a significant portion of its assets in a single Underlying Portfolio, it will be particularly sensitive to the risks associated with that Underlying Portfolio may have a significant effect on the Portfolio’s net asset value. The Portfolio will bear a pro rata share of the Underlying Portfolio’s expenses.

The Portfolio may use derivative instruments to gain exposure to certain markets, sectors or regions as alternatives to direct investments, to adjust the Portfolio duration, to provide increased flexibility in asset allocation, to earn income and to otherwise seek to enhance returns or to hedge foreign currency exposure. Use of these instruments may involve certain costs and risks such as liquidity risk, interest rate risk, mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those investments.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates over a short period of time

could cause significant losses in the market value of the Portfolio’s fixed income investments.

Asset Allocation Portfolio (unaudited)

     Sector Allocation 6/30/19

Sector	% of Net Assets
Domestic Equity	46.6%
Fixed Income	31.5%
Foreign Equity	15.3%
Short-Term Investments & Other Net Assets	6.6%

     Sector Allocation is subject to change.

Investors should be aware of the risks of investments in foreign securities, particularly investments in securities of companies in developing nations. These include the risks of currency fluctuation, of political and economic instability and of less well-developed government supervision and regulation of business and industry practices, as well as differences in accounting standards. Small cap stocks also may carry additional risk. Smaller or newer issuers are more likely to realized more substantial growth as well as suffer more significant losses than larger or more established issuers. Investments in such companies can be both volatile and more speculative. Bonds and other debt obligations are affected by changes in interest rates, inflation and the creditworthiness of their issuers. High yield bonds generally have greater price swings and higher default risks than investment grade bonds.

The Portfolio obtains its exposure to equity and fixed income securities by investing in other Series Fund portfolios (Underlying Portfolios). Each of the Underlying Portfolios has its own investment risks, and the Portfolio is indirectly exposed to all the risks of the Underlying Portfolios in which it invests, including that risk that an Underlying Portfolio will not perform as expected. To the extent that the Portfolio invests a significant portion of its assets in a single Underlying Portfolio, it will be particularly sensitive to the risks associated with that Underlying Portfolio may have a significant effect on the Portfolio’s net asset value. The Portfolio will bear a pro rata share of the Underlying Portfolio’s expenses.

The Portfolio may use derivative instruments to gain exposure to certain markets, sectors or regions as alternatives to direct investments, to adjust the Portfolio duration, to provide increased flexibility in asset allocation, to earn income and to otherwise seek to enhance returns or to hedge foreign currency exposure. Use of these instruments may involve certain costs and risks such as liquidity risk, interest rate risk, mispricing or improper valuation. Certain derivatives involve leverage, which could magnify losses, and portfolios investing in derivatives could lose more than the principal amount invested in those investments.

The U.S. federal funds rate has been subject to moderate increases over the course of the last three years. A significant rise in interest rates over a short period of time

could cause significant losses in the market value of the Portfolio’s fixed income investments.

NOTE 1. ORGANIZATION

Northwestern Mutual Series Fund, Inc. (the “Series Fund”) is registered as an open-end management investment company under the Investment Company Act of 1940, as amended (“1940 Act”). The Series Fund is also considered an investment company following the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946. The Series Fund consists of the Growth Stock Portfolio, Focused Appreciation Portfolio, Large Cap Core Stock Portfolio, Large Cap Blend Portfolio, Index 500 Stock Portfolio, Large Company Value Portfolio, Domestic Equity Portfolio, Equity Income Portfolio, Mid Cap Growth Stock Portfolio, Index 400 Stock Portfolio, Mid Cap Value Portfolio, Small Cap Growth Stock Portfolio, Index 600 Stock Portfolio, Small Cap Value Portfolio, International Growth Portfolio, Research International Core Portfolio, International Equity Portfolio, Emerging Markets Equity Portfolio, Government Money Market Portfolio, Short-Term Bond Portfolio, Select Bond Portfolio, Long-Term U.S. Government Bond Portfolio, Inflation Protection Portfolio, High Yield Bond Portfolio, Multi-Sector Bond Portfolio, Balanced Portfolio and Asset Allocation Portfolio (each, a “Portfolio” or collectively, the “Portfolios”). All of the outstanding shares of each Portfolio are held by an affiliate, The Northwestern Mutual Life Insurance Company (“Northwestern Mutual”), for its segregated asset accounts (either directly or indirectly through one or more underlying Portfolios operating as affiliated fund of funds). The Government Money Market Portfolio is a government money market fund under Rule 2a-7 of the 1940 Act.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Series Fund in the preparation of its financial statements.

A. Use of Estimates— The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of 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.

B. Foreign Income and Capital Gains Taxes— The Portfolios may be subject to income taxes imposed by certain countries in which they invest. Foreign withholding taxes on dividends and interest are netted against income and separately disclosed in the Statements of Operations.

Some of the Portfolios may be subject to capital gains taxes imposed by certain countries in which they invest. Any applicable foreign capital gains tax is accrued daily based upon net unrealized gains, and may be payable following the sale of any applicable investments.

C. Federal Income Taxes— The Portfolios’ policy is to continue to comply with the requirements of the Internal Revenue Code that are applicable to regulated investment companies and to distribute all of their taxable income to their respective shareholders. The Portfolios also intend to distribute sufficient net investment income and net capital gains, if any, so that they will not be subject to excise tax, as applicable, on distributable income and gains.

In accordance with the authoritative guidance for uncertainty in income taxes, management of the Series Fund has reviewed all open tax years (2015 to 2018) for major jurisdictions and concluded there was no material impact to the Portfolios’ net assets or results of operations. There is no material tax liability relating to uncertain income tax positions taken or expected to be taken in future tax returns. The Portfolios are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next 12 months.

D. Distributions— Dividends from net investment income and net realized capital gains are declared and paid each business day for the Government Money Market Portfolio and at least annually for the remaining Portfolios, when applicable.

E. Other— The Portfolios record security transactions on trade date. The basis for determining cost on sale of securities is identified cost. Interest income is recorded daily on the accrual basis and dividend income is recorded on the ex-dividend date or as soon as information from issuers is available. Where applicable, dividends are recorded net of foreign withholding tax. Discounts and premiums on securities purchased are amortized using the effective interest method. Expenses directly attributable to a Portfolio are incurred by the respective Portfolio. Expenses that are not directly attributable to one or more

Portfolios are allocated among applicable Portfolios on an equitable and consistent basis considering such things as the nature and type of expenses and the relative net assets of the Portfolios. The Portfolios consider highly liquid temporary cash investments purchased with an original maturity of less than three months to be cash equivalents. Cash equivalents are included in the short-term investments on the Schedule of Investments as well as in investments on the Statement of Assets and Liabilities. Temporary cash overdrafts are reported as a payable to custodian.

F. New Accounting Pronouncements— In March 2017, the FASB issued Accounting Standards Update No. 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities” (ASU 2017-08). ASU 2017-08 amends the amortization period for certain purchased callable debt securities, held at a premium, shortening such period to the earliest call date. The amendments are effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2018. The ASU has been adopted, and the impacts are not material.

In August 2018, the FASB issued Accounting Standards Update 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The update introduces new fair value disclosure requirements, eliminates some prior fair value disclosure requirements, and modifies certain existing fair value disclosure requirements. ASU 2018-13 will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. In 2018, management early adopted certain aspects that allow removal of certain disclosure requirements. Management is currently assessing the potential impact of the remaining requirements to future financial statements.

NOTE 3. SECURITY VALUATION

For purposes of calculating a net asset value, Portfolio securities and other assets are valued as of the close of trading on the New York Stock Exchange (“Exchange”) on each day during which the Exchange is open for trading.

The Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Codification defines fair value as the price that a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. It establishes and requires disclosure of a fair value hierarchy, separately for each major category of asset and liability, which segregates fair value measurements into levels. A summary of the fair value hierarchy is described below:

• Level 1 — fair value is determined by unadjusted quoted prices in active markets for identical securities or derivatives

• Level 2 — fair value is determined by other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, and other data used in fair valuation)

• Level 3 — fair value is determined by significant unobservable inputs (including the Portfolios’ own assumptions in determining fair value)

The categorization of a value determined for a financial instrument within the hierarchy is based upon the pricing transparency of the instrument and does not necessarily correspond to the Portfolios’ perceived risk of that instrument.

The following is a description of the valuation techniques and significant inputs used in determining the value of the Portfolios’ investments classified as Level 1 and Level 2 in the fair value hierarchy:

• Equity securities (common and preferred stock) for which market quotations are readily available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are traded. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price. Equity securities traded only in the over-the-counter market and not on a securities exchange are valued at the last sale price or closing bid price, if no sales have occurred. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy. Additionally, for foreign securities, fair value procedures are used if a significant event occurs

193

Notes to Financial Statements (unaudited)

between the close of the foreign market and the U.S. market close. The fair value price is reflected as Level 2 in the fair value hierarchy where applicable.

• Fixed income securities, including corporate, convertible and municipal bonds and notes, U.S. government agencies, U.S. treasury obligations, sovereign issues, bank loans, and non-U.S. bonds are generally valued on the basis of service provider prices that use broker dealer quotations or valuation estimates from internal pricing models. The service providers’ internal models use inputs that are observable such as issuer details, interest rates, yield curves, call features, maturities, credit risks/spreads and default rates. Securities that use similar valuation techniques and inputs as described above are categorized as Level 2 in the fair value hierarchy.

• Fixed income securities purchased on a delayed delivery basis are marked to market daily until settlement at the forward settlement date and are categorized as Level 2 in the fair value hierarchy.

• Mortgage related and asset backed securities are generally issued as separate tranches, or classes, of securities within each deal. These securities are normally valued by pricing service providers that use broker dealer quotations or valuation estimates from their internal pricing models. The pricing models for these securities usually consider tranche level attributes, current market data, estimated cash flows and market-based yield spreads for each tranche, and incorporate deal collateral performance, as available. Mortgage related and asset backed securities that use similar valuation techniques and inputs as described above are categorized as Level 2 in the fair value hierarchy.

• Investments in open-end mutual funds (including other Portfolios) are valued at the mutual fund’s closing net asset value per share and are categorized as Level 1 in the fair value hierarchy. Investments in privately held mutual funds are valued at the mutual fund’s closing net asset value per share and are categorized as Level 2 in the fair value hierarchy.

• Money market investments, other than in the Government Money Market Portfolio, are generally valued by a pricing service. All securities in the Government Money Market Portfolio are valued using amortized cost, unless the current market value differs substantially from the amortized cost, at which time the securities are marked to market. Because the value is not obtained from a quoted price in an active market, such securities are reflected as Level 2 in the fair value hierarchy.

• Listed derivatives, such as futures or option contracts, which are actively traded on a national securities exchange, are stated at the last reported sale or settlement price on the day of valuation and are categorized as Level 1 in the fair value hierarchy.

• Centrally cleared swaps and over-the-counter financial derivatives, such as foreign currency contracts, options contracts, or swap agreements derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. These derivatives are normally valued on the basis of quotes obtained from brokers and dealers or pricing services. Depending on the product and the terms of the transaction, the value of the derivatives can be estimated using a series of techniques, including simulation pricing models. The pricing models use inputs that are observed from actively quoted markets such as issuer details, indices, spreads, interest rates, curves, dividends and exchange rates. Financial derivatives that use similar valuation techniques and inputs as described above are categorized as Level 2 in the fair value hierarchy.

The following is a description of the valuation techniques and significant inputs used in determining the value the Portfolios’ investments classified as Level 3 in the fair value hierarchy:

• Securities and other assets for which market quotes are not readily available are valued at fair market value as determined in good faith in accordance with procedures adopted by the Series Fund’s Board of Directors (“Board”). Market quotes are considered not readily available in circumstances where there is an absence of current or reliable market-based data (e.g. trade information or broker quotes). The factors considered in reaching these values at June 30, 2019 included, but were not limited to, broker quotes, analysis of the likely outcome of pending litigation, liquidity, prepayment speed, duration and recoverability.

194

Notes to Financial Statements (unaudited)

A table summarizing each Portfolio’s investments under this hierarchy is included following each Portfolio’s Schedule of Investments. Transfers between investment levels may occur as markets fluctuate and/or the availability of data used in investments’ valuation changes. For fair valuations using significant unobservable inputs, U.S. GAAP requires a reconciliation of the beginning to ending balances for reported fair values that presents changes attributable to total realized and unrealized gains or losses, purchases and sales, and transfers in or out of the Level 3 category during the period. Additionally, U.S GAAP requires quantitative information regarding the significant unobservable inputs used in the determination of fair value of assets categorized as Level 3 in the fair value hierarchy. In accordance with the requirements, a Level 3 reconciliation and details of significant unobservable inputs have been included in the notes to the Schedule of Investments for Portfolios that have a material amount of Level 3 investments. As of June 30, 2019, there were no Portfolios that owned a material amount of Level 3 securities.

The Series Fund has adopted policies and procedures which govern the pricing of Portfolio securities. The Board has delegated the day-to-day responsibility for pricing Portfolio securities and other investments to Mason Street Advisors, LLC (“MSA”), the Portfolios’ investment adviser, Northwestern Mutual in its capacity as fund administrator, and State Street Bank and Trust Company in its capacity as fund accountant, subject to the oversight of a Pricing Committee appointed by the Board and comprised of representatives of MSA, Northwestern Mutual and Series Fund officers. The Pricing Committee is charged with the primary and day-to-day operational responsibility for executing the valuation process. The Pricing Committee has been delegated the authority to approve the override of any prices as permitted under the pricing policy and procedures approved by the Board and any variances from these pricing procedures when appropriate. All such actions are subject to further review and approval by the Board at its next regular meeting.

NOTE 4. SECURITIES AND OTHER INVESTMENTS

A. Delayed Delivery Transactions and When-Issued Securities— Certain Portfolios may engage in securities transactions on a when-issued or delayed delivery basis. In these transactions, the securities’ prices and yields are fixed on the date of the commitment, with payment and delivery scheduled for a future date. During this period, the securities are subject to market fluctuations. When delayed delivery purchases are outstanding, a Portfolio will earmark liquid assets on its records in amounts sufficient to meet the purchase price. A Portfolio may dispose of or renegotiate a delayed delivery transaction, which may result in a capital gain or loss.

B. Repurchase Agreements— Certain Portfolios may engage in repurchase transactions. Under the terms of a typical repurchase agreement, a Portfolio takes possession of an underlying debt obligation subject to an obligation of the seller to repurchase, and a Portfolio to resell, the obligation at an agreed upon price and time. The underlying securities for all repurchase agreements are held in safekeeping at the Portfolio’s custodian or designated sub-custodians under tri-party repurchase agreements. The market value of the collateral must be equal to or exceed at all times the total amount of the repurchase obligations, including interest. Securities purchased under repurchase agreements are reflected as an asset on the Statements of Assets and Liabilities. Generally, in the event of counterparty default, a Portfolio has the right to use the collateral to offset losses incurred. If the counterparty should default, a Portfolio will seek to sell the securities which it holds as collateral. This could involve procedural costs or delays in addition to a loss on the securities if their value should fall below their repurchase price.

C. Restricted Securities— Certain Portfolios may invest in securities that are subject to legal or contractual restrictions on resale. These securities may be sold privately, but are required to be registered or exempted from registration before being sold to the public. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult.

D. Foreign Currency Transactions— Certain Portfolios may have securities and other assets and liabilities denominated in foreign currencies which are translated into U.S. dollar amounts on the date of valuation. Purchases and sales of securities and income items denominated in foreign currencies are translated into U.S. dollar amounts on the respective dates of such transactions. When the Portfolios purchase or sell a foreign security they may enter into a foreign currency exchange contract to minimize exchange rate risk from the trade date to the settlement date of such transaction. Such foreign currency exchange contracts are marked to market daily.

The Portfolios do not separately report the results of operations due to fluctuations in foreign exchange rates on investments

195

Notes to Financial Statements (unaudited)

from the changes arising from changes in market prices of securities held. Such fluctuations are included with the net realized or unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales of foreign currencies, currency gains or losses realized between the trade date and the settlement date on security transactions, and the differences between the amounts of income and foreign withholding taxes recorded on the Portfolios’ books and the U.S. dollar equivalent of the amounts actually received or paid.

E. Mortgage Backed and Asset Backed Securities— Certain Portfolios may invest in mortgage backed securities, including collateralized mortgage obligations, and asset backed securities. Mortgage backed securities are interests in pools of residential or commercial mortgage loans and asset backed securities are interests in pools of other assets, including various types of loans and credit card receivables. These securities provide a monthly payment, consisting of both a principal and interest component. Interest payments may be based on either fixed rates or adjustable rates. Receipt of principal payment reduces the outstanding par amount of the security and may generate realized gains or losses. Yields on mortgage backed securities are affected by interest and prepayment rates, which, in turn, are influenced by a variety of economic, geographical, social and other factors. Maturities on mortgage backed securities represent stated maturity dates. Actual maturity dates may differ based on prepayment rates. Unlike mortgage backed securities issued or guaranteed by the U.S. government or one of its sponsored entities, mortgage backed securities and asset backed securities issued by private issuers do not have a government or government sponsored entity guarantee. These issuers may provide credit enhancements through external entities such as financial institutions or through the structuring of the transaction itself. There is no guarantee that credit enhancements, if any, will be sufficient to prevent losses.

F. Inflation-Indexed Bonds— Certain Portfolios may invest in inflation-indexed bonds. Inflation-indexed bonds are fixed income securities whose principal value is periodically adjusted to the rate of inflation. The interest rate on these bonds is generally fixed at issuance at a rate lower than typical bonds. Over the life of an inflation-indexed bond, interest will be paid based on a principal value, which is adjusted for inflation. Any increase in the principal amount of an inflation-indexed bond will be included as interest income in the applicable Portfolio’s Statement of Operations even though investors do not receive their principal until maturity.

G. Short Sales— Certain Portfolios may enter into short sale transactions. A short sale is a transaction in which a Portfolio sells a security it does not own in anticipation of a decline in the market price of the security. Securities sold in short sale transactions and the interest payable on such securities, if any, are reflected as a liability on the Statements of Assets and Liabilities. A Portfolio is obligated to deliver the security at the market price at the time the short position is closed. The risk of loss on a short sale transaction is theoretically unlimited, because there is no limit to the cost of replacing the security sold short, whereas losses from purchase transactions cannot exceed the total amount invested.

H. Financing Transactions— Certain Portfolios may enter into financing transactions. In a financing transaction, the Portfolio transfers a security to a counterparty with a simultaneous agreement to repurchase the same security at an agreed upon price and future settlement date. For U.S. GAAP purposes, a financing transaction is accounted for as a secured borrowing and not as a purchase or sale. During the term of the borrowing, the Portfolio is entitled to the interest on the security. The difference between the sale price and repurchase price is included in net investment income with the cost of the secured borrowing transaction being recorded in interest expense over the term of the borrowing. The Portfolio will benefit from the transaction if the income earned on the investment purchased with the cash received in the financing transaction exceeds the interest expense incurred by the Portfolio. If the interest expense exceeds the income earned, the Portfolio’s net investment income and dividends to shareholders may be adversely impacted. Financing transactions involve the risk that the market value of the securities that the Portfolio is required to repurchase may decline below the agreed upon repurchase price of those securities. For the period ended June 30, 2019, the Long-Term U.S. Government Bond Portfolio entered into financing transactions utilizing various U.S. Treasury bonds.

I. Loan Participation and Assignments— Certain Portfolios may invest in direct debt instruments which are interests in amounts owed to lenders or lending syndicates by corporate, governmental, or other borrowers. The Portfolios’ investments in a loan may be in the form of either actual participation in loans or assignments of all or part of the loans from third parties. A loan is often administered by a bank or other financial institution that acts as an agent for all holders. The agent administers the terms of the loan which are specified in the loan agreement. The Portfolios may invest in multiple series or

196

Notes to Financial Statements (unaudited)

tranches of a loan, each of which can have different terms and associated risks. The Portfolios generally do not have a right to enforce compliance with the terms of the loan agreement and as a result, the Portfolios may be subject to the credit risk of the borrower and lender that is selling the loan agreement. When the Portfolios purchase assignments from lenders they acquire direct rights against the borrower of the loan. The Portfolios may also enter into unfunded loan commitments, which are contractual obligations for future funding. Unfunded loan commitments can include lines of credit, which may require the Portfolios to grant additional cash to the borrower upon demand from the borrower. These unfunded loan commitments are in fact a future obligation in full, although a percentage of the loan amount may not be utilized by the borrower. When investing in a loan, the Portfolios have the right to receive principal, interest and any fees from the lender selling the loan agreement and only when the payments are received by the lender from the borrower. There may also be a commitment fee due to the Portfolios based on the unused portion of the line of credit of the floating rate loan. In certain cases, the Portfolios may be entitled to a penalty fee if there was a prepayment of a floating rate loan by the borrower. Fees that are earned or paid will be reflected as interest income or interest expense on the Statements of Operations. As of June 30, 2019, there were no unfunded loan commitments outstanding.

J. Reverse Repurchase Agreements— Certain Portfolios may enter into reverse repurchase agreements. In a reverse repurchase agreement, a Portfolio delivers a security in exchange for cash to a financial institution, the counterparty, with a simultaneous agreement to repurchase the same or substantially the same security at an agreed upon price and date. The Portfolio is entitled to receive principal and interest payments, if any, made on the security delivered to the counterparty during the term of the agreement. Cash received in exchange for securities delivered plus accrued interest payments to be made by the Portfolio to counterparties are reflected as a liability on the Statements of Assets and Liabilities. Interest payments made by a Portfolio to counterparties are recorded as a component of interest expense on the Statements of Operations. In periods of increased demand for the security, a Portfolio may receive a fee for use of the security by the counterparty, which may result in interest income to the Portfolio. When effecting reverse repurchase transactions, the Portfolio will hold securities of a dollar amount equal in value to the securities subject to the reverse repurchase agreement in a segregated account. As of June 30, 2019, there were reverse repurchase agreements held in the Long-Term U.S. Government Bond Portfolio.

K. Zero Strike Warrants— Certain Portfolios may invest in low exercise price call warrants (zero strike warrants). Zero strike warrants are issued by banks or broker-dealers and allow the fund to gain exposure to common stocks in markets that place restrictions on direct investments by foreign investors and may or may not be traded on an exchange. Income received from zero strike warrants is recorded as dividend income in the Statement of Operations. To the extent the fund invests in zero strike warrants whose returns correspond to the performance of a foreign stock, investing in zero strike warrants will involve risks similar to the risks of investing in foreign securities. Additional risks associated with zero strike warrants include the potential inability of the counterparty to fulfill their obligations under the warrant, inability to transfer or liquidate the warrants and potential delays or an inability to redeem before expiration under certain market conditions.

NOTE 5. DERIVATIVE INSTRUMENTS

The Portfolios may use derivative instruments for various purposes, including as a cash management strategy, to earn income and enhance returns, to increase or decrease exposure to a particular market, to manage or adjust the risk profile of the Portfolio, to hedge exposure to a foreign currency, or as an alternative to direct investments. Because the Portfolios are required to account for derivative instruments at fair value and recognize changes in fair value through the Statements of Operations, the Portfolios’ derivatives do not qualify for hedge accounting treatment.

Certain Portfolios segregate cash to cover margin requirements for derivative positions. These amounts are denoted as “Cash Collateral for Derivative Positions” on the Statements of Assets and Liabilities.

A. Futures Contracts— Certain Portfolios invest in futures contracts as an alternative to investing in individual securities and could be exposed to market risk due to changes in the value of the underlying securities or due to an illiquid secondary market. Futures contracts are marked to market daily based upon quoted settlement prices. The Portfolios receive from or pay to brokers an amount of cash equal to the daily fluctuation in the value of the contracts. Such receipts or payments, known as the “variation margin,” are recorded by the Portfolios as unrealized gains or losses. When a contract is closed, the

197

Notes to Financial Statements (unaudited)

Portfolios record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

B. Forward Foreign Currency Contracts— The Portfolios may enter into forward foreign currency contracts to hedge against exchange rate risk arising from investments in securities denominated in foreign currencies or as part of an investment strategy. Contracts are valued at the contractual forward rate and are marked to market daily, with the change in market value recorded as an unrealized gain or loss. When the contracts are closed, a realized gain or loss is recorded. Risks may arise from changes in market value of the underlying instruments and from the possible inability of counterparties to meet the terms of their contracts.

C. Options— Certain Portfolios may write call and put options on futures, swaps, securities or currencies they own or in which they may invest. Writing put options tends to increase a Portfolio’s exposure to the underlying instrument. Writing call options tends to decrease a Portfolio’s exposure to the underlying instrument. The Portfolio receives a premium on the sale of a call option but gives up the opportunity to profit from any increase in the value of the security above the exercise price of the option. When a Portfolio writes a put option, it is exposed to a decline in the price of the underlying security. When a Portfolio writes a call or put option, an amount equal to the premium received is recorded as a liability and subsequently marked to market to reflect the current value of the option written. These liabilities are reflected as written options outstanding in the Statements of Assets and Liabilities. Payments received or made, if any, from writing options with premiums to be determined on a future date are reflected as such on the Statements of Assets and Liabilities. Premiums received from writing options which expire are treated as realized gains. Premiums received from writing options which are exercised or closed are added to the proceeds or offset against amounts paid on the underlying future, swap, security or currency transaction to determine the realized gain or loss. A Portfolio as a writer of an option has no control over whether the underlying future, swap, security or currency may be sold (called) or purchased (put) and as a result bears the market risk of an unfavorable change in the price of the future, swap, security or currency underlying the written option. There is a risk a Portfolio may not be able to enter into a closing transaction because of an illiquid market.

Certain Portfolios may also purchase call and put options on futures, swaps, securities or currencies they own or in which they may invest. Purchasing call options tends to increase a Portfolio’s exposure to the underlying instrument. Purchasing put options tends to decrease a Portfolio’s exposure to the underlying instrument. The Portfolio pays a premium on the purchase of a put option but receives the opportunity to profit from any increase in the value of the security above the exercise price of the option. When a Portfolio purchases a call option, it is exposed to a decline in the price of the underlying security. Premiums paid are reflected in the Statements of Assets and Liabilities as an investment and are subsequently marked to market to reflect the current value of the option. Premiums paid from purchasing options which expire are treated as realized losses. Premiums paid for purchasing options which are exercised or closed are added to the amount paid or offset against the proceeds on the underlying future, swap, security or currency transaction to determine realized gain or loss. The risk associated with a Portfolio purchasing call or put options is limited to the premium paid.

D. Swap Agreements— The Portfolios may enter into swap agreements on interest rate, total return and credit default to manage their exposure to interest rates, foreign currencies, investment style risk and credit risk or as an alternative to direct investing. In connection with these agreements, securities may be identified as collateral in accordance with the terms of the respective swap agreements. Swap agreements are privately negotiated in the over-the-counter market (“OTC swaps”) and may be executed in a multilateral or other trade facility platform, such as a registered commodities exchange (“centrally cleared swaps”).

Swaps are marked to market daily based upon quotations from market makers or values from third party vendors, which may include a registered commodities exchange, and the change in value, if any, is recorded as unrealized gain or loss in the Statements of Operations. Daily changes in the valuation of centrally cleared swaps, if any, are recorded as a receivable or payable for the change in value as appropriate (“variation margin”) on the Statements of Assets and Liabilities. OTC swap payments received or made at the beginning of the measurement period of the swap are reflected on the Statements of Assets and Liabilities. Upfront payments are amortized to realized gain or loss. Upon termination of the swap, unamortized upfront payments are recorded as realized gain or loss in the Statements of Operations. A liquidation payment received or made at the termination of the swap is recorded as realized gain or loss in the Statements of Operations. Net periodic payments received by the Portfolios are included as part of realized gain (loss) on the Statements of Operations. Entering into these agreements involves, to varying degrees, elements of credit and market risk in excess of the amounts recognized on the

198

Notes to Financial Statements (unaudited)

Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform and that there may be unfavorable changes in interest rates.

Interest Rate Swaps — Interest rate swap agreements involve the exchange by a Portfolio with another party to pay or receive a set of cash flows, e.g., an exchange of floating rate payments for fixed rate payments based on a notional amount of principal.

Total Return Swaps — Total return swap agreements involve commitments to pay or receive a financing rate in exchange for the total return of an underlying reference entity, both based on notional amounts. To the extent the total return of the security or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, a Portfolio will receive a payment from or make a payment to the counterparty.

Credit Default Swaps — Credit default swap agreements involve one party making a series of payments to another party in exchange for the right to receive a cash payment equal to the notional value of the swap in the event of a default by a third party, typically corporate issues or sovereign issues of an emerging market country. A Portfolio may use credit default swaps to provide a measure of protection against defaults of the issuers where the Portfolio owns or has exposure to the corporate or sovereign issue or to take an active long or short position on the likelihood of a particular issuer’s default.

As a seller of protection, the Portfolio generally receives an upfront payment and/or a fixed rate of income throughout the term of the swap provided that there is no credit event. As the seller, the Portfolio adds leverage to its investments because the Portfolio has investment exposure on the notional amount of the swap. As a buyer of protection, the Portfolio generally makes an upfront payment or pays a fixed rate of interest throughout the term of the swap provided that there is no credit event. The Portfolio generally receives an amount up to the notional value of the swap if a credit event occurs.

Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues or sovereign issues of an emerging market country serve as an indicator of the current status of the payment/performance risk and represent the likelihood of a credit event occurring. The implied credit spread of a particular referenced entity reflects the cost of selling protection and may include upfront payments required to be made to enter into the agreement. For credit default swap agreements on credit indices, the quoted market prices and resulting values serve as the indicator of the current status of the payment/performance risk. Wider credit spreads and increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the referenced entity’s credit soundness and indicate a greater likelihood a credit event could occur as defined under the terms of the agreement. Open credit default swaps on corporate or sovereign issues and credit indices are disclosed in the Schedules of Investments.

If the Portfolio is a seller of protection and a credit event occurs, the Portfolio will either pay to the buyer of the protection an amount equal to the notional value of the swap and may take delivery of the obligation or pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation. The maximum potential amount of future payments (undiscounted) that a Portfolio as a seller of protection could be required to make under a credit default swap agreement would be equal to the notional amount of the agreement. Notional amounts and fair market value of all credit default swap agreements outstanding for each Portfolio are disclosed in the Schedules of Investments. These maximum potential amounts would be partially offset by any recovery values of the referenced obligations, upfront payments received upon entering into the agreement, or net amounts received by the Portfolio from the settlement of credit default swap agreements purchasing protection for the same referenced obligation.

E. Derivative Disclosures— Derivative positions held by the Portfolios by contract type and primary risk exposure, including location on the Statement of Assets and Liabilities and value as of June 30, 2019, are (amounts in thousands):

NOTE 6. PORTFOLIO RISK

In the normal course of business, the Portfolios trade financial instruments and enter into financial transactions where risk of potential loss exists. Security values fluctuate (market risk) and may decline due to factors affecting securities markets in general, particular industries represented in the securities markets or conditions specifically related to a particular company. Failure of the other party to a transaction to perform (credit risk), for example by not making principal and interest payments when due, reduces the value of the issuer’s debt and could reduce the Portfolios’ income. Similar to credit risk, the Portfolios may be exposed to counterparty risk, or the risk that an institution or other entity with which the Portfolios have unsettled or open transactions will fail to make required payments or otherwise comply with the terms of the instrument, transaction or contract. The potential loss could exceed the value of the financial assets recorded in the financial statements. Some of the Portfolios’ investments may be illiquid and the Portfolios may not be able to vary the portfolio investments in response to changes in economic and other conditions. If a Portfolio is required to liquidate all or a portion of its investments quickly, the Portfolio may realize significantly less than the value at which it previously recorded those investments.

Master Netting Arrangements

The Portfolios are subject to various Master Agreements that govern the terms of certain transactions. Master Repurchase Agreements and Global Master Repurchase Agreements are in place that governs repurchase, reverse repurchase, and sale-buyback financing transactions. Master Securities Forward Transaction Agreements are in place that govern the settlement of certain forward settling transactions including to-be-announced securities, delayed-delivery or sale-buyback financing transactions. Customer Account Agreements and related addenda are in place that govern certain cleared derivative transactions including futures and cleared OTC derivatives. International Swaps and Derivatives Association, Inc. Master Agreements and Credit Support Annexes (“ISDA agreements”) are in place that governs certain OTC financial derivative

203

transactions. ISDA agreements maintain provisions for general obligations, representations, agreements, collateral and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA agreement. The terms of Master Agreements may reduce counterparty risk with respect to transactions governed by the Master Agreement under certain circumstances. Certain Portfolios have agreements with counterparties that contain provisions, or contingency features, that allow net settlement in the event of contract termination and permit termination by either party prior to maturity upon the occurrence of certain stated events, such as failure to pay or bankruptcy. In addition, certain agreements specify other events, the occurrence of which would allow one of the parties to terminate. For example, a downgrade in credit rating of a counterparty would allow the fund to terminate while a decline in the Portfolio’s net assets of more than a certain percentage would allow the counterparty to terminate. In such a situation, the counterparty involved would have the option to waive the triggering event or liquidate the affected positions pursuant to the terms of the related agreement. The aggregate amount of derivatives in a liability position is disclosed in Note 5.

Offsetting Assets and Liabilities

Certain Portfolios are parties to enforceable master netting or similar agreements which provide for the right of offset under certain circumstances. The Portfolios have made an accounting policy election not to offset qualifying financial and derivative instruments on the Statements of Assets and Liabilities. As such, all financial and derivative instruments are presented on a gross basis on the Statements of Assets and Liabilities. The impacts of netting arrangements that provide the right to offset are detailed below (amounts in thousands). The net amount represents the net receivable or payable that would be due from or to the counterparty in the event of default. Exposure from borrowings and other financing transactions such as repurchase agreements and certain forward settling transactions can only be netted across transactions governed under the same Master Agreement with the same legal entity. For certain Portfolios, derivative amounts do not reconcile to the Statements of Assets and Liabilities due to the Statements of Assets and Liabilities including derivatives that are not covered under master netting or similar agreements. The amount of collateral, for the period ended June 30, 2019, has been limited such that the net amount cannot be less than zero.

With respect to certain Portfolios, MSA has engaged and overseessub-advisers who manage theday-to-day investment operations of such Portfolios. MSA pays eachsub-adviser a fee based on the average daily net assets of each such Portfolio out of its investment management fee.

Compliance fees are paid to Northwestern Mutual, an affiliate of the Series Fund. The compliance fees paid are for the compensation, benefits and expenses of the Chief Compliance Officer and compliance staff. The amounts paid relate only to the Chief Compliance Officer and compliance staffs’ duties and functions performed for the Series Fund.

NOTE 8. FEDERAL INCOME TAX MATTERS

Taxable distributions from net investment income and realized capital gains in the Portfolios may differ from book amounts earned during the period due to differences in the timing of capital gains recognition and due to the reclassification of certain gains or losses between capital and income. The differences between cost amounts for book purposes and tax purposes are primarily due to the tax treatment of deferred losses, passive foreign investment companies, and financing transactions.

It is the policy of the Portfolios to reclassify the net effect of permanent differences between book and taxable income to capital accounts on the Statements of Assets and Liabilities. Permanent differences primarily relate to character differences with respect to income on swaps, foreign currency transactions, foreign bond sales, passive foreign investment companies and paydowns on structured product investments.

A summary of the Portfolios’ capital loss carryovers as of December 31, 2018 is provided below:

NOTE 12. LITIGATION

The Index 500 Stock, Small Cap Value and Equity Income Portfolios are among the defendants in two lawsuits relating to their receipt of proceeds from the 2007 Tribune Co. leveragedbuy-out (“Tribune LBO”) transaction. One lawsuit, filed in a U.S. Bankruptcy Court by a group of unsecured creditors, asserts that the directors and officers of Tribune Co. intentionally defrauded Tribune creditors because Tribune was either insolvent or rendered insolvent by the transactions. Counsel for the Series Fund and other institutional defendants filed a motion to dismiss the intentional fraudulent transfer case in the Southern District of New York and the district court judge granted the motion to dismiss without leave to amend. The dismissal is being appealed to the U.S. Court of Appeals for the Second Circuit. The other set of lawsuits, filed by a group of secured creditors in various U.S. federal courts, asserts that the transfer of proceeds to the above-noted Portfolios (and

214

Notes to Financial Statements (unaudited)

other shareholders) as part of the Tribune LBO were constructively fraudulent. Following the grant of a motion to dismiss the secured creditors’ constructive fraud claim by the District Court, the affirmation of that dismissal by the U.S. Court of Appeals for the Second Circuit, followed by a denial of a motion for reconsideration, the Plaintiffs requested review of the decision by the U.S. Supreme Court. Based on a decision issued by the U.S. Supreme Court in a different case, the constructive fraudulent transfer case was remanded to the Second Circuit Court of Appeals for a determination of the effect of the recent decision on the claims asserted in the Tribune case. Proceedings are pending in the Second Circuit Court of Appeals. The lawsuits allege no misconduct by the Portfolios or management, and management intends to vigorously defend all claims and allegations. The plaintiffs in both lawsuits seek to recover amounts paid to Tribune shareholders in the leveraged buyout transaction, plus interest and attorneys’ fees and expenses. The value of the proceeds received by these Portfolios in 2007, and the percentage the proceeds represent of each Portfolio’s net assets as of June 30, 2019, were: Index 500 Stock Portfolio $977,000 (0.03%) of net assets; Small Cap Value Portfolio $618,000 (0.11% of net assets); and Equity Income Portfolio $2,873,000 (0.37% of net assets). Management has not concluded that a loss is reasonably likely to occur, and therefore no loss accrual has been recorded.

Annual Contract Review Process

Under Section 15(c) of the Investment Company Act of 1940, as amended (the “1940 Act”), contracts for investment advisory services are required to be reviewed, evaluated and approved by a majority of an investment company’s independent directors each year. In addition, each investment company is required to disclose in its annual or semi-annual report, as applicable, the material factors and conclusions that formed the basis for the board’s approval or renewal of any investment advisory agreements within the investment company’s most recently completed fiscal half-year period.

At least annually, the Board of Directors (the “Board”) of Northwestern Mutual Series Fund, Inc. (the “Series Fund”) considers and votes upon the renewal of the investmentsub-advisory agreements between Mason Street Advisors, LLC (“Mason Street Advisors”) and each of thesub-advisers of those portfolios of the Series Fund (each, a “Portfolio” and collectively, the “Portfolios”) for which Mason Street Advisors and the Board have appointed asub-adviser. In order to afford the Board the opportunity to focus on a smaller number of relationships at any one meeting, the Board considers the annual continuation of thesub-advisory agreements on a staggered basis during the course of the year.

Board Approvals During theSix-Month Period Ended June 30, 2019

At its February 28, 2019 meeting, the Board, including the directors who are not “interested persons” (as that term is defined in the 1940 Act) of the Series Fund or Mason Street Advisors (the “Independent Directors”), unanimously approved the continuance of the Amended and Restated Advisory Agreement between the Series Fund and Mason Street Advisors with respect to each of the Series Fund’s Portfolios (the “Advisory Agreement”).

Also at its February 28, 2019 meeting, the Board, including the Independent Directors, unanimously approved the continuance of a (1) Second Amended and Restated InvestmentSub-Advisory Agreement between Mason Street Advisors and Mellon Investments Corporation (“Mellon”) relating to the Series Fund’s Growth Stock Portfolio, and a (2) Third Amended and restated InvestmentSub-Advisory Agreement between Mason Street Advisors and Wellington Management Company LLP (“Wellington”) relating to the Series Fund’s Small Cap Growth Stock, Large Cap Core Stock and Mid Cap Growth Stock Portfolios.

At its June 5, 2019 meeting, the Board, including the Independent Directors, unanimously approved the continuance of a (1) Third Amended and Restated InvestmentSub-Advisory Agreement between Mason Street Advisors and Massachusetts Financial Services Company (“MFS”) relating to the Series Fund’s Research International Core Portfolio, (2) Second Amended and Restated InvestmentSub-Advisory Agreement between Mason Street Advisors and FIAM LLC (“FIAM”) relating to the Series Fund’s International Growth Portfolio, (3) Fourth Amended and Restated InvestmentSub-Advisory Agreement between Mason Street Advisors and Templeton Investment Counsel, LLC (“Templeton”) relating to the Series Fund’s International Equity Portfolio, (4) Second Amended and Restated InvestmentSub-Advisory Agreement between Mason Street Advisors and Fiduciary Management, Inc. (“FMI”) relating to the Series Fund’s Large Cap Blend Portfolio, and (5) an Amended InvestmentSub-Advisory Agreement between Mason Street Advisors and Aberdeen Asset Managers Limited (“Aberdeen”) relating to the Series Fund’s Emerging Markets Equity Portfolio. Mellon, Wellington, MFS, FIAM, Templeton, FMI and Aberdeen are sometimes collectively referred to herein as the“Sub-Advisers,” their respectivesub-advised Portfolios are collectively referred to herein as the“Sub-Advised Portfolios” and the respective InvestmentSub-Advisory Agreements with theSub-Advisers are collectively referred to herein as the“Sub-Advisory Agreements.”

In determining whether to approve the continuance of the Advisory Agreement and theSub-Advisory Agreements on behalf of the Series Fund, the Board requested and received detailed information from Mason Street Advisors and theSub-Advisers in advance of each meeting to assist them in their evaluation, including information compiled by certain independent providers of evaluative data. While particular focus was given to an evaluation of the services, performance, fees, costs, and certain other relevant information under such Agreements at the meeting at which their continuation is formally considered, the evaluation process with respect to Mason Street Advisors and theSub-Advisers and the nature, extent and quality of

218

Approval and Continuance of Investment Advisory and Sub-Advisory Agreements (unaudited)

the services they provide to the Portfolios is an ongoing one. As a result, the Board’s consideration of such services, and the performance, fees, costs and other relevant factors was informed by information provided and deliberations that occurred at other meetings throughout the year.

The Independent Directors received a memorandum from their counsel advising them of their responsibilities in connection with the review of the Advisory Agreement andSub-Advisory Agreements, and summarizing the legal standards governing the review and approval of these Agreements. The Independent Directors reviewed these standards with their counsel during the course of the meetings, including how these standards should be applied to the review of information relating tosub-advisers under the Series Fund’s manager of managers structure. During the course of their deliberations, the Independent Directors had the opportunity to meet privately without representatives of Mason Street Advisors and theSub-Advisers, and were represented throughout the process by legal counsel.

Continuation of the Advisory Agreement between the Series Fund and Mason Street Advisors

At its February 28, 2019 meeting, the Board, including the Independent Directors, unanimously approved the continuance of the Advisory Agreement with respect to each Series Fund Portfolio. In addition to the information presented by and about Mason Street Advisors and its affiliates during the course of that meeting, the materials provided to the directors in advance of the meeting included Mason Street Advisor’s Section 15(c) Report, which contained responses to the information request letter prepared by counsel to the Independent Directors requesting certain information from Mason Street Advisors designed to assist the directors in fulfilling their responsibilities when considering the continuation of the Advisory Agreement. Those materials also included an independent report prepared by Broadridge (“Broadridge Report”) for each of the Portfolios. The Broadridge Report provided details regarding the fees, expenses, and performance returns captured over a variety of measurement periods, as well as comparative information associated with a Broadridge peer group for each Portfolio as selected by Broadridge based on the Portfolio’s investment style, characteristics and asset levels, and further customized to filter out funds with different share class characteristics and fund structures. The Broadridge Report included an executive summary of the performance and expense information compiled by Broadridge to facilitate the directors’ review. The materials provided to the Independent Directors included an overview from the Mason Street Advisors’ Chief Compliance Officer(“MSA-CCO”) of Mason Street Advisors’ compliance program, as well as theMSA-CCO’s Annual Compliance Report summarizing the results of his review and assessment of the adequacy of Mason Street Advisors’ compliance program. The Independent Directors were also provided with an overview from the Series Fund’s Chief Compliance Officer(“SF-CCO”) of the Series Fund’s compliance program along with theSF-CCO’s Annual Compliance Report summarizing the results of his review and assessment of the adequacy of the Series Fund’s compliance program. In addition to the information presented at the February 28, 2019 meeting, the directors’ considerations were informed by the information regularly provided to them throughout the year regarding the Portfolios and Mason Street Advisors, their experience with and knowledge of the nature and quality of services provided by Mason Street Advisors to the Portfolios and their interactions with representatives of Mason Street Advisors and its affiliates.

The material factors and conclusions that formed the basis for the Board’s approval of the continuance of the Advisory Agreement include those discussed below. The directors evaluated the information they deemed relevant on aPortfolio-by-Portfolio basis. No one particular factor was identified as determinative, but rather it was a combination of all the factors and conclusions that formed the basis for the determinations made by the directors. Further, different directors may have placed greater weight on certain factors than did other directors.

Nature, Extent and Quality of Services. In considering the nature, extent and quality of Mason Street Advisors’ services, factors considered by the directors included Mason Street Advisors’ overall business, organization and management structure, and the tenure and experience of Mason Street Advisors’ investment personnel. The directors considered the performance of each Portfolio over various time periods as presented at the February 28, 2019 meeting and at each of the quarterly meetings prior thereto.

Included as part of their review were the presentations and information provided by Mason Street Advisors regarding the services provided by Mason Street Advisors, including investment management and administrative services and services

219

Approval and Continuance of Investment Advisory and Sub-Advisory Agreements (unaudited)

related to the oversight and evaluation of the varioussub-advisers appointed to manage the majority of the Series Fund’s Portfolios. The directors noted favorably the collaborative efforts of Mason Street Advisor’s portfolio managers providingday-to-day portfolio management services for the two allocation and three index-based Portfolios. The directors recognized that in addition to the investment advisory services provided, Mason Street Advisors and its affiliates provided administrative services critical to the operation of the Portfolios and the servicing of the Series Fund’s investors. The risk management infrastructure implemented by Mason Street Advisors, the Series Fund’s compliance program and compliance infrastructure, and its various compliance policies and procedures, oversight of brokerage and trading, and succession planning were also considered by the directors.

Based on their review of these factors, and reflecting upon their experience with Mason Street Advisors’ services provided to the Portfolios, the Board concluded, as part of their overall evaluation of the Advisory Agreement, that they were satisfied with the nature, extent and quality of services provided by Mason Street Advisors with respect to each Portfolio, including the resources committed by Mason Street Advisors and its affiliates in providing those services, and the experience and capabilities of the personnel rendering such services.

Investment Performance. The Broadridge Report and reporting information provided by Lipper assisted the Board in its evaluation of the performance of the Portfolios. The directors considered the investment performance of each of the Portfolios over a variety of periods. In addition to considering performance for each Portfolio for both short- and long-term periods, the directors considered: (i) a comparison of each Portfolio’sone-, three-, and five-year (as applicable) performance to the returns of appropriate benchmarks and indices, and to the performance averages of each Portfolio’s respective Broadridge and Lipper peer groups for the same periods; (ii) the Broadridge overall star rating and Lipper quintile rating for each Portfolio; and (iii) the Broadridge and Lipper performance rankings for each Portfolio for theone-, three- and five-year time periods (as applicable). The directors evaluated each Portfolio’s performance against these peer groups and industry benchmarks and indices. They viewed this information as providing an objective comparative benchmark against which they could assess the performance of the Portfolios. The directors were also presented with information from Mason Street Advisors regarding the relevant market conditions and other factors affecting the performance of each Portfolio. The directors evaluated a chart provided by Broadridge regarding each Portfolio’s net returns relative to net expenses for the five-year period ended December 31, 2018, focusing in particular on those Portfolios in the bottom half on a comparative basis. The directors considered the steps that already had been taken to improve the performance of those Portfolios, which included, in all but one instance, the appointment of newsub-advisers. The directors noted that, with respect to the Growth Stock Portfolio, performance improvement plans implemented by the Portfolio’ssub-adviser would continue to be monitored.

In addition to performance information presented at the meeting, the directors considered the detailed performance information, market commentary, portfolio analysis and portfolio manager presentations they received periodically throughout the year. The directors gave weight to their ongoing discussions with senior management at Mason Street Advisors concerning Portfolio performance, as well as discussions regarding performance, investment process and investment strategies among the Board, theSub-Advisers and the portfolio managers of the Portfolios that occurred at meetings from time to time. While attentive to short-term performance and what it might indicate, the directors generally placed greater emphasis on longer-term performance.

The directors considered the performance returns of the Portfolios as reported by Broadridge, which indicated that 15 of the 27 Portfolios were ranked in the first quartile of their respective Broadridge category peer groups for theone-year period ended December 31, 2018, that 13 of the 27 Portfolios were ranked in the first or second quartile for each of theone-, three- and five-year periods ended December 31, 2018, and that 19 of the 27 Portfolios were ranked in the first or second quartile for the five-year period ended December 31, 2018. The directors also considered the performance returns of the Portfolios as reported by Lipper, which indicated that 19 of the 27 Portfolios were ranked in either the first or second quartile for theone-year period ended December 31, 2018, and that 19 of the 27 Portfolios were ranked in the first or second quartile for the three-year period ended December 31, 2018.

Based on the Board’s review of investment performance over various periods, an analysis of the factors resulting in the performance of certain of the Portfolios, the Board concluded that, considering investment performance within the context

220

Approval and Continuance of Investment Advisory and Sub-Advisory Agreements (unaudited)

of its overall determinations regarding the Advisory Agreement, it was satisfied with the relative investment performance of each Portfolio over time.

Management Fees and Other Expenses. The Broadridge Report assisted the Board in the evaluation of the relative expenses of the Portfolios. The directors reviewed a comparison of the management fees of the Portfolios and those of an independently selected peer group of mutual funds for each of the Portfolios. The directors further considered the expenses of each Portfolio and a comparison of those expenses with each Portfolio’s respective peer group and fund category group as a guide to help assess the reasonableness of each Portfolio’s advisory fees and net and total expense ratios. The Broadridge Report also included additional comparative information relating to other fee components, including costs relating to custodial services, shareholder reporting, audit expenses and advisory fees. The directors used the comparative data to help assess the reasonableness of each Portfolio’s advisory fee, although they acknowledged that it was difficult to make precise comparisons with other funds because of the differing manner in which service providers bundle the services they provide and the fees they charge.

In evaluating the level of management fees paid by each Portfolio, the directors considered the structure and size of the Portfolios, the fees paid by each Portfolio under the Advisory Agreement, the expense cap and fee waiver agreements in place for certain Portfolios, and the amounts waived or reimbursed by Mason Street Advisors under such agreements. In considering Mason Street Advisors’ management fees on a stand-alone basis, the directors took into consideration that the management fees compensated Mason Street Advisors for a broader range of services (both investment management and administrative services) than may be included under a typical investment management contract, and concluded that as a result of these additional services, viewing Mason Street Advisors’ management fees in light of Broadridge-reported averages might not provide a complete frame of reference for comparative purposes.

The directors considered information made available regarding compensation paid to Mason Street Advisors by other clients and differences between the fees paid by these clients and the fees paid by the Series Fund. The directors recognized that Mason Street Advisors’ other clients were affiliated institutional accounts. The directors were informed that the advisory fees charged to these other clients were based on different factors and considerations, including differences in the level and nature of services provided by Mason Street Advisors, differences in the applicable regulatory structure, differences in the investment objectives and policies of these other clients and, moreover, the affiliated nature of the other relationships.Accordingly, the directors did not consider the advisory fees charged to these other clients as particularly relevant in assessing the advisory fees charged under the Advisory Agreement.

The directors also evaluated each Portfolio’s total operating expenses over various periods. The directors commented specifically on Mason Street Advisors’ consistent attention to managing portfolio expenses. The directors expressed satisfaction with the continued good expense rankings of the Portfolios, observing that all but one of the Portfolios were ranked in Broadridge’s first or second quartile (meaning lowest expenses) for total expenses within their respective category groups at December 31, 2018, with 23 of the Portfolios ranking in the first quartile. The directors considered the savings that continue to be achieved by the 2017 change in the Portfolios’ custodian, and the resulting favorable impact on the expense rankings of the Portfolios. The directors considered that, with respect to the Large Cap Blend Portfolio, which had ranked in the 55th percentile in expenses for the year ended December 31, 2018, the advisory fee waiver that was being implemented by Mason Street Advisors should improve the Portfolio’s expense ranking as assets in the Portfolio increase.

Based on their review of the management fees and other expenses, the comparative data, the performance of each Portfolio, and other factors deemed relevant by the directors, the Board concluded that the management fees and total operating expenses of each of the Portfolios (as modified by the applicable expense waivers and fee caps) were reasonable in relation to the nature, scope and quality of advisory services provided by Mason Street Advisors and the performance of the Portfolios.

Costs and Profitability. The directors reviewed information provided by Mason Street Advisors regarding the profitability realized by Mason Street Advisors with respect to the Portfolios. The directors considered Mason Street Advisors’ pricing methodology for its services as investment adviser, noting that it had remained consistent with prior years. The directors considered Mason Street Advisors’ quarterly presentation to the directors regarding Mason Street Advisors’ revenues,

221

Approval and Continuance of Investment Advisory and Sub-Advisory Agreements (unaudited)

expenses, income and profit margins allocable to its services to the Portfolios on an aggregate and a per Portfolio basis, and reviewed Mason Street Advisors’ allocation methodology with respect to its revenues and expenses. The profitability information presented for the directors’ consideration was supplemented by information regarding the range of expenses in each Portfolio’s respective Broadridge peer group and fund group category and the ranking of each Portfolio within the applicable peer group and fund group category. In connection with its review of the profitability of Mason Street Advisors’ services to the Portfolios, the directors considered services provided by affiliates of Mason Street Advisors.

The directors considered the allocation of fees as between Mason Street Advisors and eachsub-adviser as well as applicable asset levels, breakpoints, total expenses and management fee waivers that are in place for those Portfolios. As part of the allocation of fees, the Board considered Mason Street Advisors’ decision for the upcoming year to add an advisory fee waiver for the Large Cap Blend Portfolio, to increase advisory fee waivers with respect to six of the Portfolios, and to retain all other existing fee waivers and expense caps at their current level for an additionalone-year period. The directors also considered the impact to Mason Street Advisors’ profitability of the recent change in the model for the delivery of fund accounting services to the Series Fund.

The directors also received information on soft dollar arrangements and any other benefits to Mason Street Advisors or its affiliates arising from its relationship with the Portfolios, including (as applicable) the participation of fund families advised by certainsub-advisers to the Portfolios on the retail brokerage platform maintained by a brokerage affiliate of Mason Street Advisors, the participation of such fund families in a certain mutual fund partner program offered by such brokerage affiliate of Mason Street Advisors, and the payment of fees by the fund families based upon participation on the brokerage platform and the mutual fund partner program maintained by the brokerage affiliate of Mason Street Advisors.

The directors also considered that the assets of certain of the Portfolios are invested in certain exchange traded funds (“ETFs”) beyond the limitations of the 1940 Act, in reliance on certain exemptive orders issued by the Securities and Exchange Commission to such ETFs. The Board concluded that the advisory fees payable to Mason Street Advisors by such Portfolios were based on services that were in addition to, and not duplicative of, services provided by the ETFs. The Board also considered the fund of funds model employed by the Asset Allocation and Balanced Portfolios and the reduced advisory fees charged for those two Portfolios.

The directors recognized the difficulty in obtaining reliable comparative data about mutual fund managers’ profitability, since such information generally is not publicly available and may be impacted by numerous factors specific to the investment adviser and its method of allocating revenues and expenses. Based on their review of the profitability provided for each Portfolio, the Board concluded that they were satisfied that Mason Street Advisors’ level of profitability arising from each Portfolio was not excessive.

Economies of Scale. The directors also considered whether each Portfolio’s expense structure permitted economies of scale to be shared with Portfolio investors. The directors considered that breakpoints are contained in the management fee schedules for 20 of the 27 Portfolios and further considered the extent to which the Portfolios may benefit from economies of scale through those breakpoints. The directors also considered Mason Street Advisors’ explanation of why breakpoints for the remaining Portfolios had not been established, including that those Portfolios were ranked the lowest or close to the lowest in terms of total expenses of each Portfolio’s respective peer group as determined by Broadridge or benefited from advisory fee waivers and/or expense limitation agreements put in place by Mason Street Advisors. Also considered was Mason Street Advisors’ commitment to continue to regularly work with the Board to evaluate the need for additional breakpoints or fee waivers as each Portfolio’s assets grow over time. In particular, the directors considered that Mason Street Advisors had agreed to add an advisory fee waiver to the Large Cap Blend Portfolio and to increase fee waivers with respect to six of the Portfolios. Based on this information, the Board concluded that, within the context of its overall determinations regarding the Advisory Agreement, each Portfolio’s fee structure reflected appropriate economies of scale for the benefit of Portfolio investors.

Approval and Continuance of Investment Advisory and Sub-Advisory Agreements (unaudited)

Continuation of theSub-Advisory Agreements between Mason Street Advisors and CertainSub-Advisers

At its February 28, 2019 and June 5, 2019 meetings, the Board, including the Independent Directors, unanimously approved the continuance of theSub-Advisory Agreements with respect to theSub-Advised Portfolios. At those meetings, the directors received a presentation from representatives of eachSub-Adviser involved in the management of the respectiveSub-Advised Portfolios. In addition to the information presented by and about theSub-Advisers during the course of those meetings, the directors also had eachSub-Adviser’s Section 15(c) Report, which contained responses to the information request letter prepared by counsel to the Independent Directors requesting certain information from theSub-Advisers designed to assist the directors in fulfilling their responsibilities when considering the continuation of theSub-Advisory Agreements. The directors also had Mason Street Advisors’ Executive Summary and Overview of eachSub-Adviser and other materials prepared by Mason Street Advisors. The materials contained detailed information on performance over multiple time periods, expenses, brokerage commissions, portfolio turnover, style consistency, key portfolio statistics and metrics, and other factors with respect to each of theSub-Advised Portfolios. The materials also contained an analysis of theSub-Advisers’ responses to the compliance questions contained in the Section 15(c) Report and the observations of the Series Fund’s Chief Compliance Officer regarding the compliance structure and practices of eachSub-Adviser. The directors also considered their experience with and knowledge of the nature and quality of the services provided by theSub-Advisers and their ongoing discussions with representatives of Mason Street Advisors, its affiliates and eachSub-Adviser.

The material factors and conclusions that formed the basis for the Board’s approval of the continuance of each of theSub-Advisory Agreements include those discussed below. The directors evaluated a variety of information they deemed relevant on aPortfolio-by-Portfolio basis. No one particular factor was identified as determinative, but rather it was a combination of all the factors and conclusions that formed the basis for the determinations made by the Board. Further, different directors may have placed greater weight on certain factors than did other directors.

Nature, Extent and Quality of Services. In considering the nature, extent and quality of eachSub-Adviser’s services, the directors reviewed eachSub-Adviser’s financial strength, assets under management and overall reputation. The directors evaluated the investment strategies employed by eachSub-Adviser, as well as the personnel providing such services with respect to theSub-Advised Portfolio. In particular, the directors considered update presentations given by the portfolio managers and how theSub-Advised Portfolios were being positioned in the current market environment. The directors also considered Mason Street Advisors’ reports on due diligence visits and conference calls that had been conducted with certain of theSub-Advisers.

With respect to theSub-Advisory Agreements reviewed in February, the directors considered the potential impact of the modified role of the principal portfolio manager assigned to the Growth Stock Portfolio, for which Mellon serves assub-adviser, and whether the Portfolio was likely to achieve strong performance under the current portfolio management team. The directors also considered Mellon’s management presentation provided to the Board outlining recent organizational changes and the evolution of the portfolio management team for the Portfolio, as well as the loss of certain analysts on the investment team, and assessed the potential impact of these developments on investment management resources. The directors considered the performance track record of the current portfolio management team and the firm’s new compensation structure in place for portfolio managers. The directors also considered the impact of the 2018 merger of Mellon into an affiliated investment adviser, as well as recent layoffs affecting Mellon’s parent company. The directors took into consideration Mellon’s representations that the parent company layoffs have not affected the investment teams, and information regarding the firms’ planned investments into its asset management business. With respect to Wellington, the directors commented favorably regarding the depth of talent on the firm’s investment team, particularly in light of the addition of analysts in certain sectors, and the capabilities of the portfolio manager providing services to the Large Cap Core Stock Portfolio.

With respect to theSub-Advisory Agreements considered for continuance in June, the directors considered recent and planned workforce reductions by Templeton’s parent company, as well as Templeton’s assurances that the reductions would not impact Templeton’s investment professional staff. The directors observed that while Templeton had experienced recent declines in assets under management, it was not anticipated that the declines would have a negative impact on the firm’s

ability to attract and retain investment professionals. The directors also considered recent changes made by Templeton to its global equity investment group and research platform structure, concluding that such changes should improve the efficiency of the firm’s investment management process. With respect to Aberdeen, thesub-adviser to the Emerging Markets Equity Portfolio, the directors considered updated information about the continued impact of the 2017 merger of Aberdeen’s parent company with Standard Life plc, and remained confident that the merger had not negatively affected the portfolio management team assigned to the Portfolio, or the investment process previously employed by Aberdeen. With respect to the Research International Core Portfolio, for which MFS serves assub-adviser, the directors considered that certain changes were made in the portfolio managers responsible for the Portfolio, but noted favorably that, in light of the research-driven investment process employed by MFS, such personnel changes were unlikely to cause a negative impact. The directors also considered certain changes in the sector team leads on the MFS investment team and viewed favorably the background and experience of the newly-appointed sector leads. With respect to the Large Cap Blend Portfolio, for which FMI serves assub-adviser, the directors considered the current positioning of the holdings in the Portfolio and expressed a high degree of confidence in the portfolio manager for the Portfolio. With respect to the International Growth Portfolio, for which FIAM serves assub-adviser, the directors considered recent sector lead changes, and concluded that such changes would not be impactful to the firm’s ability to continue to provide high-quality services to the Portfolio.

The directors also considered eachSub-Adviser’s investment philosophy and process and the scope of services provided by theSub-Advisers. Consideration was also given to theSub-Advisers’ respective reputations and experience in providing investment management services and the performance of eachSub-Advised Portfolio. Based on their review of these factors, their discussions with theSub-Advisers, and their experience with the services provided by theSub-Advisers for the respectiveSub-Advised Portfolios, the Board concluded, within the context of their overall determinations regarding theSub-Advisory Agreements, that they were satisfied with the nature, extent and quality of services, and the resources committed by eachSub-Adviser in providing those services, and were satisfied with the experience and capabilities of theSub-Advisers and the personnel associated with theSub-Advised Portfolios.

Investment Performance. The directors reviewed the investment performance of each of theSub-Advised Portfolios over a variety of time periods. In addition to considering performance for eachSub-Advised Portfolio for both short- and long-term periods, the directors considered: (i) a comparison of eachSub-Advised Portfolio’sone-, three-, and five-year (as applicable) performance to the returns of appropriate benchmarks and indices, and to the performance averages of eachSub-Advised Portfolio’s respective Broadridge and Lipper peer groups for the same periods; (ii) the Broadridge overall star rating and Lipper quintile rating for eachSub-Advised Portfolio; and (iii) the Broadridge and Lipper performance rankings for eachSub-Advised Portfolio for theone-, three- and five-year time periods (as applicable). The directors evaluated eachSub-Advised Portfolio’s performance against these peer groups and industry benchmarks and indices, and viewed this information as providing an objective comparative benchmark against which they could assess the performance of theSub-Advised Portfolios. The directors also considered the performance of accounts managed in a similar manner by each of theSub-Advisers and information from theSub-Advisers regarding any significant differences in the performance of those accounts from that of theSub-Advised Portfolios.

With respect to the Growth Stock Portfolio managed by Mellon, the directors considered the performance track record of the current portfolio management team and the firm’s new compensation structure in place for portfolio managers. The directors noted that the Growth Stock Portfolio was ranked in Lipper’s 27th percentile for the year ended December 31, 2018, and had experienced strong recent performance. The directors considered the repeatability of such performance in light of the changes to the portfolio management team at Mellon. The directors considered that there had been no changes to the firm’s investment philosophy or the investment process employed for the Growth Stock Portfolio as a result of the portfolio management transition. With respect to the Portfolios managed by Wellington, the directors considered the challenged performance for theone-year period ended December 31, 2018. With respect to the Small Cap Growth Stock Portfolio managed by Wellington, the directors commented favorably on the Portfolio’s overall strong long-term performance record. The directors also noted favorably the portfolio manager’s presentation to the Board, and the explanation offered for the Portfolio’s near-term underperformance. With respect to the Mid Cap Growth Stock Portfolio managed by Wellington, the directors observed that the portfolio manager was adhering to the investment process that had previously been communicated to the Board, despite short-term performance challenges. The directors also commented favorably on the

224

Approval and Continuance of Investment Advisory and Sub-Advisory Agreements (unaudited)

quality of the presentation provided to the Board by the portfolio manager for the Mid Cap Growth Stock Portfolio. With respect to the Mid Cap Growth Stock Portfolio and the Large Cap Core Stock Portfolio, also managed by Wellington, the directors noted that it was premature to draw any conclusions regarding underperformance for 2018 given Wellington’s short tenure assub-adviser for these Portfolios. The directors commented favorably regarding the depth of talent on the firm’s investment team and the capabilities of the portfolio manager providing services to the Large Cap Core Stock Portfolio.

With respect to the Research International Core Portfolio managed by MFS, the directors identified no performance concerns. The directors commended the strong performance record for the International Growth Portfolio during FIAM’s tenure assub-adviser. With respect to the International Equity Portfoliosub-advised by Templeton the directors noted recent performance challenges and considered the structural changes implemented by Templeton to address these performance concerns. With respect to the Emerging Markets Portfolio, the directors considered Aberdeen’s explanation for the underperformance during 2017, and noted that the Portfolio had outperformed its benchmark for the three-month andone-year periods ended March 31, 2019. With respect to the Large Cap Blend Portfolio, the directors considered the explanation of FMI’s portfolio manager regarding the impact of the extended bull market on the Portfolio’s performance, and observed that the Portfolio continued to perform as expected given its stated investment style. The directors also noted that the Portfolio had outperformed during the fourth quarter of 2018.

In addition to performance information presented at the meeting, the directors considered the detailed performance information, market commentary, portfolio analysis and portfolio manager presentations they received periodically throughout the year. While attentive to short term performance and what it might indicate, the directors generally placed greater emphasis on longer-term performance. For the reasons set forth above, the Board concluded that, considering investment performance within the context of its overall determinations regarding theSub-Advisory Agreements, it was satisfied with the relative investment performance of theSub-Advised Portfolios.

Management Fees and Other Expenses. The directors evaluated the reasonableness of the management fees and total expenses paid by theSub-Advised Portfolios under theSub-Advisory Agreements. The directors considered the fees paid by eachSub-Advised Portfolio. The directors also considered thesub-advisory fees paid by Mason Street Advisors out of its management fee, including a comparison of those fees with fees charged by the respectiveSub-Advisers for similarly-managed accounts. In considering the level of management fees, the directors evaluated the size of theSub-Advised Portfolios, expenses assumed by Mason Street Advisors, and the existing expense limitation and/or fee waiver arrangements agreed to by Mason Street Advisors with respect to eachSub-Advised Portfolio.

As part of their evaluation, the directors reviewed an independent analysis prepared by Broadridge of comparative expense data for eachSub-Advised Portfolio. Broadridge provided data as of December 31, 2018 comparing eachSub-Advised Portfolio’s net and total expenses with those of a peer group of funds utilized in connection with variable insurance products sharing a similar investment classification, objective and asset allocation, each as selected by Broadridge. The directors considered the comparative data as a guide to help assess the reasonableness of eachSub-Advised Portfolio’s net and total expense ratios. The directors considered that 26 of theSub-Advised Portfolios were in the first or second Broadridge quartiles (meaning lowest) for total expenses associated with their respective category groups for the period ended December 31, 2018, and that six of the sevenSub-Advised Portfolios at issue were ranked in Broadridge’s first quartile for total expenses for the same period. The directors considered that the remainingSub-Advised Portfolio was ranked in the 55th percentile for net total expenses, but also noted that FMI had agreed to asub-advisory fee reduction in connection with the renewal of itsSub-Advisory Agreement.

The directors also reviewed the breakpoints contained in the advisory fee schedules for theSub-Advised Portfolios. The directors took into consideration the advisory fee waiver and/or expense limitation agreements that were in place with respect to each of theSub-Advised Portfolios, except for the Small Cap Growth Stock Portfolio, which ranked in the first quartile of its peer group for both net and total expenses (meaning lowest expenses).

Based on their review of the above information and other factors deemed relevant by the directors, the Board concluded that the management fees and total operating expenses of each of theSub-Advised Portfolios were reasonable in relation to the

225

Approval and Continuance of Investment Advisory and Sub-Advisory Agreements (unaudited)

nature, scope and quality of services provided and the performance of theSub-Advised Portfolios and the expense caps and waivers that were in place or were being implemented.

Costs and Profitability. The directors reviewed information provided by Mason Street Advisors regarding the profitability realized by Mason Street Advisors from theSub-Advised Portfolios. The directors considered Mason Street Advisors’ quarterly presentation to the directors regarding Mason Street Advisors’ revenues, expenses, income and profit margins allocable to its services to theSub-Advised Portfolios on an aggregate and a per Portfolio basis, and Mason Street Advisors’ allocation methodology with respect to revenues and expenses. The profitability information presented for the directors’ consideration was supplemented by the aforementioned information regarding the expense-based rankings of eachSub-Advised Portfolio within the Portfolio’s respective Broadridge peer group category. The directors also considered the profitability information related to certain of theSub-Advised Portfolios where such information had been provided. In all instances, including those where profitability information had not been provided, the directors recognized thatsub-advisory fees were the result ofarm’s-length negotiations between Mason Street Advisors and eachSub-Adviser. The directors also recognized that there are limitations inherent in allocating costs and calculating profitability for organizations such as theSub-Advisers, and that it is difficult to make comparisons of profitability among investment advisers because comparative information is not generally publicly available and, when available, such information had been developed using a variety of assumptions and other factors. The directors concluded that they had received sufficient information to evaluate theSub-Advisers’ costs and profitability.

The directors considered certainfall-out benefits that may be realized by Mason Street Advisors and its affiliates due to their relationship with theSub-Advised Portfolios, including (as applicable) the participation of fund families advised by certainSub-Advisers to theSub-Advised Portfolios on the retail brokerage platform maintained by a brokerage affiliate of Mason Street Advisors, the participation of such fund families in certain a mutual fund partner program offered by such brokerage affiliate, and the payment of fees by the fund families based upon participation on the brokerage platform and the mutual fund partner program maintained by the brokerage affiliate of Mason Street Advisors. The directors also reviewed information concerning certain of theSub-Advisers’ soft dollar arrangements and any other benefits to theSub-Advisers arising from their relationships with theSub-Advised Portfolios. Based on their review, the Board concluded, within the context of their overall determinations regarding theSub-Advisory Agreements, that they were satisfied that the fees paid by each of theSub-Advised Portfolios, and the profits realized by Mason Street Advisors and theSub-Advisers due to their relationship with theSub-Advised Portfolios, were not excessive.

Economies of Scale. The directors also considered whether eachSub-Advised Portfolio’s expense structure permitted economies of scale to be shared with such Portfolio’s investors. The directors considered the breakpoints contained in the advisory fee schedules for theSub-Advised Portfolios and the extent to which theSub-Advised Portfolios may benefit from economies of scale through those breakpoints. The directors also took into account the expense limitation arrangements in place for the Large Cap Blend, International Growth, Research International Core and Emerging Markets Equity Portfolios, and the fee waiver arrangements in place with respect to the Large Cap Core Stock, Mid Cap Growth Stock, Large Cap Blend, Growth Stock, International Growth, Research International Core, International Equity and Emerging Markets Equity Portfolios. The directors also considered the total assets and expense ratio of eachSub-Advised Portfolio. Based on this information, the Board concluded, within the context of its overall determinations regarding theSub-Advisory Agreements, that eachSub-Advised Portfolio’s fee structure reflected appropriate economies of scale for the benefit of such Portfolio’s investors.

Other Information

The directors were presented with other information to assist them in their consideration of the continuation of the Advisory Agreement andSub-Advisory Agreements, including information about the services provided by affiliates of Mason Street Advisors to the Portfolios and information regarding Mason Street Advisors’ and theSub-Advisers’ brokerage practices and commissions. The directors took into consideration reports from Mason Street Advisors on its review of the respective compliance programs of theSub-Advisers, including any recent compliance exceptions noted and the applicableSub-Adviser’s response. Also considered were key affiliations and business relationships between theSub-Advisers and their affiliates and Mason Street Advisors’ parent company and affiliates. Their review further included information relating to each Sub-

226

Adviser’s risk management infrastructure, pending or recent litigation or regulatory actions to which aSub-Adviser or its affiliates may have been a party, and the applicableSub-Adviser’s responses to those actions. The directors also considered information regarding eachSub-Adviser’s code of ethics and business continuity plans, portfolio manager compensation, portfolio turnover, succession planning and other matters they deemed relevant.

Conclusions of the Directors

Based on a consideration of the foregoing, the Board, including the Independent Directors, and assisted by the advice of legal counsel independent of Mason Street Advisors, in the exercise of their reasonable business judgment, concluded that the terms of the Advisory Agreement and theSub-Advisory Agreements were fair and reasonable and approved the continuation of each Agreement for another year as being in the best interests of each Portfolio.
