Letter from the President

Dear Shareholder:

We hope you find the semiannual report for PGIM QMA Stock Index Fund informative and useful. The report covers performance for the six-month period ended March 31, 2019.

We have important information to share with you. Effective June 11, 2018, Prudential Mutual Funds were renamed PGIM Funds. This renaming is

part of our ongoing effort to further build our reputation and establish our global brand, which began when our firm adopted PGIM Investments as its name in April 2017. Please note that only the Fund’s name has changed. Your Fund’s management and operation, along with its symbols, remained the same.*

Regarding your investments with PGIM, we believe it is important to maintain a diversified portfolio of funds consistent with your tolerance for risk, time horizon, and financial goals.

Your financial advisor can help you create a diversified investment plan that may include funds covering all the basic asset classes and that reflects your personal investor profile and risk tolerance. However, diversification and asset allocation strategies do not assure a profit or protect against loss in declining markets.

At PGIM Investments, we consider it a great privilege and responsibility to help investors participate in opportunities across global markets while meeting their toughest investment challenges. PGIM is a top-10 global investment manager with more than $1 trillion in assets under management. This investment expertise allows us to deliver actively managed funds and strategies to meet the needs of investors around the globe.

Thank you for choosing our family of funds.

Sincerely,

Stuart S. Parker, President

Benchmark Definitions

S&P 500 Index—The S&P 500 Index (the Index) is an unmanaged index of over 500 stocks of large US public companies. It gives a broad look at how stock prices in the United States have performed. The average annual total return for the Index measured from the month-end closest to the inception date of the Fund’s Class R6 shares is 7.31%.

Lipper S&P 500 Index Funds Average—The Lipper S&P 500 Index Funds Average (Lipper Average) is based on the average return of all funds in the Lipper S&P 500 Index Funds Average universe for the periods noted. Funds in the Lipper Average are passively managed, limited expense (management fee no higher than 0.50%) funds designed to replicate the performance of the S&P 500 Index on a reinvested basis. The average annual total return for the Lipper Average measured from the month-end closest to the inception date of the Fund’s Class R6 shares is 6.86%.

Investors cannot invest directly in an index or average. The returns for the Index would be lower if they included the effects of sales charges, operating expenses of a mutual fund, or taxes. Returns for the Lipper Average reflect the deduction of operating expenses, but not sales charges or taxes.

Fees and Expenses (unaudited)

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

The example is based on an investment of $1,000 held through the six-month period ended March 31, 2019. The example is for illustrative purposes only; you should consult the Prospectus for information on initial and subsequent minimum investment requirements.

Actual Expenses

The first line for each share class in the table on the following page provides information about actual account values and actual expenses. You may use the information on 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 ÷ $1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

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

The Fund’s transfer agent may charge additional fees to holders of certain accounts that are not included in the expenses shown in the table on the following page. These fees apply to individual retirement accounts (IRAs) and Section 403(b) accounts. As of the close of the six-month period covered by the table, IRA fees included an annual maintenance fee of $15 per account (subject to a maximum annual maintenance fee of $25 for all accounts held by the same shareholder). Section 403(b) accounts are charged an annual $25 fiduciary maintenance fee. Some of the fees may vary in amount, or may be waived, based on your total account balance or the number of PGIM funds, including the Fund, that you own. You should consider the additional fees that were charged to your Fund account over the six-month period when you estimate the total ongoing expenses paid over the period

PGIM QMA Stock Index Fund 9

Fees and Expenses(continued)

and the impact of these fees on your ending account value, as these additional expenses are not reflected in the information provided in the expense table. Additional fees have the effect of reducing investment returns.

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

* Fund expenses (net of fee waivers or subsidies, if any) for each share class are equal to the annualized expense ratio for each share class (provided in the table), multiplied by the average account value over the period, multiplied by the 182 days in the six-month period ended March 31, 2019, and divided by the 365 days in the Fund’s fiscal year ending September 30, 2019 (to reflect the six-month period). Expenses presented in the table include the expenses of any underlying portfolios in which the Fund may invest.

Notes to Financial Statements(unaudited)

Prudential Investment Portfolios 8 (the “Trust”) is registered under the Investment Company Act of 1940, as amended (“1940 Act”), as a diversifiedopen-end management investment company. The Trust consists of one fund: PGIM QMA Stock Index Fund (the “Fund”). Effective June 11, 2018, the Fund’s name was changed by replacing “Prudential” with “PGIM” and the Fund’s Class Q shares were renamed Class R6 shares.

The investment objective of the Fund is to provide investment results that correspond to the price and yield performance of the Standard & Poor’s 500 Composite Stock Price Index.

1. Accounting Policies

The Fund follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 946 Financial Services—Investment Companies. The following accounting policies conform to U.S. generally accepted accounting principles. The Fund consistently follows such policies in the preparation of its financial statements.

Securities Valuation:The Fund holds securities and other assets and liabilities that are fair valued at the close of each day (generally, 4:00 PM Eastern time) the New York Stock Exchange (“NYSE”) is open for trading. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The Trust’s Board of Trustees (the “Board”) has adopted valuation procedures for security valuation under which fair valuation responsibilities have been delegated to PGIM Investments LLC (“PGIM Investments” or the “Manager”). Pursuant to the Board’s delegation, the Manager has established a Valuation Committee responsible for supervising the fair valuation of portfolio securities and other assets and liabilities. The valuation procedures permit the Fund to utilize independent pricing vendor services, quotations from market makers, and alternative valuation methods when market quotations are either not readily available or not deemed representative of fair value. A record of the Valuation Committee’s actions is subject to the Board’s review, approval, and ratification at its next regularly scheduled quarterly meeting.

For the fiscal reportingperiod-end, securities and other assets and liabilities were fair valued at the close of the last U.S. business day. Trading in certain foreign securities may occur when the NYSE is closed (including weekends and holidays). Because such foreign securities trade in markets that are open on weekends and U.S. holidays, the values of some of the Fund’s foreign investments may change on days when investors cannot purchase or redeem Fund shares.

Various inputs determine how the Fund’s investments are valued, all of which are categorized according to the three broad levels (Level 1, 2, or 3) detailed in the Schedule of

PGIM QMA Stock Index Fund 39

Notes to Financial Statements(unaudited) (continued)

Investments and referred to herein as the “fair value hierarchy” in accordance with FASB ASC Topic 820—Fair Value Measurements and Disclosures.

Common and preferred stocks, exchange-traded funds, and derivative instruments, such as futures or options, that are traded on a national securities exchange are valued at the last sale price as of the close of trading on the applicable exchange where the security principally trades. Securities traded via NASDAQ are valued at the NASDAQ official closing price. To the extent these securities are valued at the last sale price or NASDAQ official closing price, they are classified as Level 1 in the fair value hierarchy. In the event that no sale or official closing price on valuation date exists, these securities are generally valued at the mean between the last reported bid and ask prices, or at the last bid price in the absence of an ask price. These securities are classified as Level 2 in the fair value hierarchy.

Investments inopen-end,non-exchange-traded mutual funds are valued at their net asset values as of the close of the NYSE on the date of valuation. These securities are classified as Level 1 in the fair value hierarchy since they may be purchased or sold at their net asset values on the date of valuation.

Securities and other assets that cannot be priced according to the methods described above are valued based on pricing methodologies approved by the Board. In the event that unobservable inputs are used when determining such valuations, the securities will be classified as Level 3 in the fair value hierarchy.

When determining the fair value of securities, some of the factors influencing the valuation include: the nature of any restrictions on disposition of the securities; assessment of the general liquidity of the securities; the issuer’s financial condition and the markets in which it does business; the cost of the investment; the size of the holding and the capitalization of the issuer; the prices of any recent transactions or bids/offers for such securities or any comparable securities; any available analyst media or other reports or information deemed reliable by the Manager regarding the issuer or the markets or industry in which it operates. Using fair value to price securities may result in a value that is different from a security’s most recent closing price and from the price used by other unaffiliated mutual funds to calculate their net asset values.

Illiquid Securities:Pursuant to Rule22e-4 under the 1940 Act, the Fund has adopted a Board approved Liquidity Risk Management Program (“LRMP”) that requires, among other things, that the Fund limit its illiquid investments that are assets to no more than 15% of net assets. Illiquid securities are those that, because of the absence of a readily available market or due to legal or contractual restrictions on resale, may not reasonably be expected to be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. The Fund may

40

find it difficult to sell illiquid securities at the time considered most advantageous by its Subadviser and may incur transaction costs that would not be incurred in the sale of securities that were freely marketable.

Restricted Securities:Securities acquired in unregistered, private sales from the issuing company or from an affiliate of the issuer are considered restricted as to disposition under federal securities law (“restricted securities”). Such restricted securities are valued pursuant to the valuation procedures noted above. Restricted securities that would otherwise be considered illiquid investments pursuant to the Fund’s LRMP because of legal restrictions on resale to the general public may be traded among qualified institutional buyers under Rule 144A of the Securities Act of 1933. Therefore, these Rule 144A securities, as well as commercial paper that is sold in private placements under Section 4(2) of the Securities Act of 1933, may be classified higher than “illiquid” under the LRMP (i.e. “moderately liquid” or “less liquid” investments). However, the liquidity of the Fund’s investments in restricted securities could be impaired if trading does not develop or declines.

Financial Futures Contracts:A financial futures contract is an agreement to purchase (long) or sell (short) an agreed amount of securities at a set price for delivery on a future date. Upon entering into a financial futures contract, the Fund is required to pledge to the broker an amount of cash and/or other assets equal to a certain percentage of the contract amount. This amount is known as the “initial margin.” Subsequent payments, known as “variation margin,” are made or received by the Fund each day, depending on the daily fluctuations in the value of the underlying security. Such variation margin is recorded for financial statement purposes on a daily basis as unrealized gain (loss). When the contract expires or is closed, the gain (loss) is realized and is presented in the Statement of Operations as net realized gain (loss) on futures transactions.

The Fund invested in financial futures contracts in order to hedge its existing portfolio securities, or securities the Fund intends to purchase, against fluctuations in value caused by changes in prevailing interest rates. Should interest rates move unexpectedly, the Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. The use of futures transactions involves the risk of imperfect correlation in movements in the price of futures contracts, interest rates and the underlying hedged assets. Since futures contracts are exchange-traded, there is minimal counterparty credit risk to the Fund since the exchanges’ clearinghouse acts as counterparty to all exchange-traded futures and guarantees the futures contracts against default.

Master Netting Arrangements:The Trust, on behalf of the Fund,is subject to various Master Agreements, or netting arrangements, with select counterparties. These are agreements which a Subadviser may have negotiated and entered into on behalf of the Fund. A master netting arrangement between the Fund and the counterparty permits the Fund to offset amounts payable by the Fund to the same counterparty against amounts to be received; and by the receipt of collateral from the counterparty by the Fund to cover the Fund’s exposure to the counterparty. However, there is no assurance that such mitigating factors are easily enforceable. In addition to master netting arrangements, the right toset-off exists when all

PGIM QMA Stock Index Fund 41

Notes to Financial Statements(unaudited) (continued)

the conditions are met such that each of the parties owes the other determinable amounts, the reporting party has the right toset-off the amount owed with the amount owed by the other party, the reporting party intends toset-off and the right ofset-off is enforceable by law. During the reporting period, there was no intention to settle on a net basis and all amounts are presented on a gross basis on the Statement of Assets and Liabilities.

Securities Lending:The Fund lends its portfolio securities to banks and broker-dealers. The loans are secured by collateral at least equal to the market value of the securities loaned. Collateral pledged by each borrower is invested in an affiliated money market fund and is marked to market daily, based on the previous day’s market value, such that the value of the collateral exceeds the value of the loaned securities. In the event of significant appreciation in value of securities on loan on the last business day of the reporting period, the financial statements may reflect a collateral value that is less than the market value of the loaned securities. Such shortfall is remedied as described above. Loans are subject to termination at the option of the borrower or the Fund. Upon termination of the loan, the borrower will return to the Fund securities identical to the loaned securities. Should the borrower of the securities fail financially, the Fund has the right to repurchase the securities in the open market using the collateral.

The Fund recognizes income, net of any rebate and securities lending agent fees, for lending its securities in the form of fees or interest on the investment of any cash received as collateral. The borrower receives all interest and dividends from the securities loaned and such payments are passed back to the lender in amounts equivalent thereto. The Fund also continues to recognize any unrealized gain (loss) in the market price of the securities loaned and on the change in the value of the collateral invested that may occur during the term of the loan. In addition, realized gain (loss) is recognized on changes in the value of the collateral invested upon liquidation of the collateral. Net earnings from securities lending are disclosed on the Statement of Operations as “Income from securities lending, net”.

Equity and Mortgage Real Estate Investment Trusts (collectively equity REITs):The Fund invests in equity REITs, which report information on the source of their distributions annually. Based on current and historical information, a portion of distributions received from equity REITs during the period is estimated to be dividend income, capital gain or return of capital and recorded accordingly. When material, these estimates are adjusted periodically when the actual source of distributions is disclosed by the equity REITs.

Securities Transactions and Net Investment Income:Securities transactions are recorded on the trade date. Realized gains (losses) from investment and currency transactions are calculated on the specific identification method. Dividend income is recorded on theex-date, or for certain foreign securities, when the Fund becomes aware of such dividends. Expenses are recorded on an accrual basis, which may require the use of certain estimates

42

by management that may differ from actual. Net investment income or loss (other than class specific expenses and waivers, which are allocated as noted below) and unrealized and realized gains (losses) are allocated daily to each class of shares based upon the relative proportion of adjusted net assets of each class at the beginning of the day. Class specific expenses and waivers, where applicable, are charged to the respective share classes. Class specific expenses include distribution fees and distribution fee waivers, shareholder servicing fees, transfer agent’s fees and expenses, registration fees and fee waivers and/or expense reimbursements, as applicable.

Taxes:It is the Fund’s policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable net investment income and capital gains, if any, to its shareholders. Therefore, no federal income tax provision is required. Withholding taxes on foreign dividends, interest and capital gains, if any, are recorded, net of reclaimable amounts, at the time the related income is earned.

Dividends and Distributions:The Fund expects to pay dividends from net investment income and distributions from net realized capital gains, if any, annually. Dividends and distributions to shareholders, which are determined in accordance with federal income tax regulations and which may differ from generally accepted accounting principles, are recorded on theex-date. Permanent book/tax differences relating to income and gain (loss) are reclassified amongst total distributable earnings (loss) andpaid-in capital in excess of par, as appropriate.

Estimates:The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

2. Agreements

The Trust, on behalf of the Fund, has a management agreement with PGIM Investments. Pursuant to this agreement, PGIM Investments has responsibility for all investment advisory services and supervises the Subadviser’s performance of such services. In addition, under the management agreement, PGIM Investments provides all of the administrative functions necessary for the organization, operation and management of the Fund. PGIM Investments administers the corporate affairs of the Fund and, in connection therewith, furnishes the Fund with office facilities, together with those ordinary clerical and bookkeeping services which are not being furnished by the Fund’s custodian and the Fund’s transfer agent. PGIM Investments is also responsible for the staffing and management of dedicated groups of legal, marketing, compliance and related personnel necessary for the operation of the Fund. The legal, marketing, compliance and related personnel are also responsible for the management and oversight of the various service providers to the Fund, including, but not limited to, the custodian, transfer agent, and accounting agent.

PGIM QMA Stock Index Fund 43

Notes to Financial Statements(unaudited) (continued)

PGIM Investments has entered into a subadvisory agreement with QMA LLC (formerly known as Quantitative Management Associates, LLC) (“QMA”). The subadvisory agreement provides that QMA will furnish investment advisory services in connection with the management of the Fund. In connection therewith, QMA is obligated to keep certain books and records of the Fund. PGIM Investments pays for the services of QMA, the cost of compensation of officers of the Fund, occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears all other costs and expenses.

The management fee paid to the Manager is accrued daily and payable monthly at an annual rate of 0.15% of the Fund’s average daily net assets up to and including $1 billion and 0.10% of such average daily net assets in excess of $1 billion. The effective management fee rate before any waivers and/or expense reimbursements was 0.15% for the six months ended March 31, 2019.

The Manager has contractually agreed, through January 31, 2020 to waive a portion of its management fee so that the effective management fee for the Fund will be 0.08% of the average daily net assets of the Fund. Separately, the Manager has contractually agreed, through January 31, 2020, to limit transfer agency, shareholder servicing,sub-transfer agency and blue sky fees, as applicable, to the extent that such fees cause the total annual operating expenses to exceed 0.18% of average daily net assets for Class R6 shares. This contractual expense limitation excludes interest, brokerage, taxes (such as income and foreign withholding taxes, stamp duty and deferred tax expenses), acquired fund fees and expenses, extraordinary expenses, and certain other Fund expenses such as dividend and interest expense and broker charges on short sales. Expenses waived/reimbursed by the Manager in accordance with this agreement may be recouped by the Manager within the same fiscal year during which such waiver/reimbursement is made if such recoupment can be realized without exceeding the expense limit in effect at the time of the recoupment for that fiscal year.

Where applicable, the Manager agrees to waive management fees or shared operating expenses on any share class to the same extent that it waives similar expenses on any other share class. In addition, total annual operating expenses for Class R6 shares will not exceed total annual operating expenses for Class Z shares. Fees and/or expenses waived and/or reimbursed by PGIM Investments may be recouped by PGIM Investments within the same fiscal year during which such waiver and/or reimbursement is made if such recoupment can be realized without exceeding the expense limit in effect at the time of the recoupment for the fiscal year.

The Trust, on behalf of the Fund, has a distribution agreement with Prudential Investment Management Services LLC (“PIMS”), which acts as the distributor of the Class A, Class C, Class I, Class Z and Class R6 shares of the Fund. The Fund compensates PIMS for

44

distributing and servicing the Fund’s Class A and Class C shares, pursuant to the plans of distribution (the “Distribution Plans”), regardless of expenses actually incurred by PIMS. The distribution fees are accrued daily and payable monthly. No distribution or service fees are paid to PIMS as distributor of the Class I, Class Z and Class R6 shares of the Fund.

Pursuant to the Distribution Plans, the Fund compensates PIMS for distribution related activities at an annual rate of up to 0.30% and 1% of the average daily net assets of the Class A and Class C shares, respectively.

For the reporting period ended March 31, 2019, PIMS received $54,272 infront-end sales charges resulting from sales of Class A shares. Additionally, for the reporting period ended March 31, 2019, PIMS received $5,524 in contingent deferred sales charges imposed upon redemptions by certain Class C shareholders. From these fees, PIMS paid such sales charges to broker-dealers, who in turn paid commissions to salespersons and incurred other distribution costs.

PGIM Investments, PIMS and QMA are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. (“Prudential”).

3. Other Transactions with Affiliates

Prudential Mutual Fund Services LLC (“PMFS”), an affiliate of PGIM Investments and an indirect, wholly-owned subsidiary of Prudential, serves as the Fund’s transfer agent. Transfer agent’s fees and expenses in the Statement of Operations include certainout-of-pocket expenses paid tonon-affiliates, where applicable.

The Fund may enter into certain securities purchase or sale transactions under Board approved Rule17a-7 procedures. Rule17a-7 is an exemptive rule under the 1940 Act, that subject to certain conditions, permits purchase and sale transactions among affiliated investment companies, or between an investment company and a person that is affiliated solely by reason of having a common (or affiliated) investment adviser, common directors, and/or common officers. Pursuant to the Rule17a-7 procedures and consistent with guidance issued by the SEC, the Trust’s Chief Compliance Officer (“CCO”) prepares a quarterly summary of all such transactions for submission to the Board, together with the CCO’s written representation that all such17a-7 transactions were effected in accordance with the Fund’s Rule17a-7 procedures. Any17a-7 transactions for the reporting period are disclosed in the “Portfolio Securities” note, below.

The Fund may invest its overnight sweep cash in the PGIM Core Ultra Short Bond Fund (the “Core Fund”), and its securities lending cash collateral in the PGIM Institutional Money Market Fund (the “Money Market Fund”), each a series of Prudential Investment Portfolios 2, registered under the 1940 Act and managed by PGIM Investments. Through the Fund’s investments in the mentioned underlying funds, PGIM Investments and/or its affiliates are paid fees or reimbursed for providing their services. Earnings from the Core Fund and Money Market Fund are disclosed on the Statement of Operations as “Affiliated dividend

6. Capital and Ownership

The Fund offers Class A, Class C, Class I, Class Z and Class R6 shares. Class A shares are sold with a maximumfront-end sales charge of 3.25%. Investors who purchase $1 million or more of Class A shares and sell these shares within 12 months of purchase are subject to a contingent deferred sales charge (“CDSC”) of 1%, although they are not subject to an initial sales charge. The Class A CDSC is waived for certain retirement and/or benefit plans. A special exchange privilege is also available for shareholders who qualified to purchase Class A shares at net asset value. Class C shares are sold with a CDSC of 1% on sales made within 12 months of purchase. Class C shares will automatically convert to Class A shares on a monthly basis approximately 10 years after purchase. Class I, Class Z and Class R6 shares are not subject to any sales or redemption charge and are available exclusively for sale to a limited group of investors.

Under certain circumstances, an exchange may be made from specified share classes of the Fund to one or more other share classes of the Fund as presented in the table of transactions in shares of beneficial interest.

The Trust has authorized an unlimited number of shares of beneficial interest at $0.001 par value per share, currently of one Fund, divided into five classes, designated Class A, Class C, Class I, Class Z and Class R6 shares.

As of March 31, 2019, Prudential, through its affiliated entities, including affiliated funds (if applicable), owned 241 Class R6 shares of the Fund. At reporting period end, three shareholders of record, each holding greater than 5% of the Fund, held 30% of the Fund’s outstanding shares.

7. Borrowings

The Trust, on behalf of the Fund, along with other affiliated registered investment companies (the “Funds”), is a party to a Syndicated Credit Agreement (“SCA”) with a group of banks. The purpose of the SCA is to provide an alternative source of temporary funding for capital share redemptions. The SCA provides for a commitment of $900 million for the period October 4, 2018 through October 3, 2019. The Funds pay an annualized commitment fee of 0.15% of the unused portion of the SCA. The Fund’s portion of the commitment fee for the unused amount, allocated based upon a method approved by the Board, is accrued daily and paid quarterly. Prior to October 4, 2018, the Funds had another SCA that provided a commitment of $900 million and the Funds paid an annualized commitment fee of 0.15% of the unused portion of the SCA. The interest on borrowings under both SCAs is paid monthly and at a per annum interest rate based upon a contractual spread plus the higher of (1) the effective federal funds rate, (2) the1-month LIBOR rate or (3) zero percent.

Certain affiliated registered investment companies that are parties to the SCA include portfolios that are subject to a predetermined mathematical formula used to manage certain benefit guarantees offered under variable annuity contracts. The formula may result in large scale asset flows into and out of these portfolios. Consequently, these portfolios may be more likely to utilize the SCA for purposes of funding redemptions. It may be possible for those portfolios to fully exhaust the committed amount of the SCA, thereby requiring the Manager to allocate available funding per a Board-approved methodology designed to treat the Funds in the SCA equitably.

The Fund utilized the SCA during the reporting period ended March 31, 2019. The balance for the 1 day that the Fund had a loan outstanding during the period was $16,903,000, borrowed at an interest rate of 3.63%. At March 31, 2019, the Fund did not have an outstanding loan amount.

8. Risks of Investing in the Fund

The Fund’s risks include, but are not limited to, some or all of the risks discussed below:

Derivatives Risk:Derivatives involve special risks and costs and may result in losses to the Fund. The successful use of derivatives requires sophisticated management, and, to the extent that derivatives are used, the Fund will depend on the Subadviser’s ability to analyze and manage derivative transactions. The prices of derivatives may move in unexpected ways, especially in abnormal market conditions. Some derivatives are “leveraged” and therefore may magnify or otherwise increase investment losses to the Fund. Other risks arise from the potential inability to terminate or sell derivatives positions. A liquid secondary market may not always exist for the Fund’s derivatives positions. In fact, many OTC

50

derivative instruments will not have liquidity beyond the counterparty to the instrument. OTC derivative instruments also involve the risk that the other party will not meet its obligations to the Fund.

Equity and Equity-Related Securities Risks:The value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which the Fund invests could go down. The Fund’s holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.

Market and Credit Risk:Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of an investment in the Fund will decline. Additionally, the Fund may also be exposed to credit risk in the event that an issuer or guarantor fails to perform or that an institution or entity with which the Fund has unsettled or open transactions defaults.

9. Recent Accounting Pronouncements and Reporting Updates

In August 2018, the Securities and Exchange Commission (the “SEC”) adopted amendments to RegulationS-X to update and simplify the disclosure requirements for registered investment companies by eliminating requirements that are redundant or duplicative of US GAAP requirements or other SEC disclosure requirements. The new amendments require the presentation of the total, rather than the components, of distributable earnings on the Statement of Assets and Liabilities and the total, rather than the components, of dividends from net investment income and distributions from net realized gains on the Statements of Changes in Net Assets. The amendments also removed the requirement for the parenthetical disclosure of undistributed net investment income on the Statements of Changes in Net Assets and certain tax adjustments that were reflected in the Notes to Financial Statements. The Manager has adopted the amendments and reflected them in the Fund’s financial statements.

In August 2018, the FASB issued Accounting Standards Update (“ASU”)No. 2018-13, which changes certain fair value measurement disclosure requirements. The new ASU, in addition to other modifications and additions, removes the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and the Fund’s policy for the timing of transfers between levels. The amendments are effective for financial statements issued for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Manager has evaluated the implications of certain provisions of the ASU and has determined to early adopt aspects related to the removal and modification of certain fair value measurement disclosures under the ASU effective immediately. At this time, the Manager is evaluating the implications of certain

other provisions of the ASU related to new disclosure requirements and any impact on the financial statement disclosures has not yet been determined.
