SPDR SERIES TRUST
NOTES TO FINANCIAL STATEMENTS
December 31, 2021 (Unaudited)

1.    Organization
SPDR Series Trust (the “Trust”), a Massachusetts business trust, registered under the Investment Company Act of 1940, as amended (“1940 Act”), is an open-end management investment company.
As of December 31, 2021, the Trust consists of eighty-two (82) series, each of which represents a separate series of beneficial interest in the Trust. The Declaration of Trust permits the Board of Trustees of the Trust (the “Board”) to authorize the issuance of an unlimited number of shares of beneficial interest at $0.01 par value. The financial statements herein relate to the following series (each a “Fund”, and collectively, the “Funds”):
SPDR Dow Jones REIT ETF
SPDR S&P Biotech ETF
SPDR S&P Dividend ETF
Each Fund is classified as a diversified investment company under the 1940 Act.
Under the Trust’s organizational documents, its officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. Additionally, in the normal course of business, the Trust enters into contracts with service providers that contain general indemnification clauses. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred.
2.    Summary of Significant Accounting Policies
The following is a summary of significant accounting policies followed by the Trust in the preparation of its financial statements:
The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) 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. Each Fund is an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.
Security Valuation
Each Fund's investments are valued at fair value each day that the New York Stock Exchange (“NYSE”) is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the NYSE is not open. Fair value is generally defined as the price 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. By its nature, a fair value price is a good faith estimate of the valuation in a current sale and may not reflect an actual

Table of Contents

NOTES TO FINANCIAL STATEMENTS  (continued)
December 31, 2021 (Unaudited)

market price. The investments of each Fund are valued pursuant to the policy and procedures developed by the Oversight Committee (the “Committee”) and approved by the Board. The Committee provides oversight of the valuation of investments for the Funds. The Board has responsibility for overseeing the determination of the fair value of investments.
Valuation techniques used to value each Fund’s investments by major category are as follows:
•   Equity investments (including preferred stocks and registered investment companies that are exchange-traded funds) traded on a recognized securities exchange for which market quotations are readily available are valued at the last sale price or official closing price, as applicable, on the primary market or exchange on which they trade. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last published sale price or at fair value.
•   Investments in registered investment companies (including money market funds) or other unitized pooled investment vehicles that are not traded on an exchange are valued at that day’s published net asset value (“NAV”) per share or unit.
•   Exchange-traded futures contracts are valued at the closing settlement price on the primary market on which they are traded most extensively. Exchange-traded futures contracts traded on a recognized exchange for which there were no sales on that day are valued at the last reported sale price obtained from independent pricing services or brokers or at fair value.
In the event prices or quotations are not readily available or that the application of these valuation methods results in a price for an investment that is deemed to be not representative of the fair value of such investment, fair value will be determined in good faith by the Committee, in accordance with the valuation policy and procedures approved by the Board.
Fair value pricing could result in a difference between the prices used to calculate a Fund's NAV and the prices used by a Fund's underlying benchmarks Various inputs are used in determining the value of a Fund's investments.
The Funds value their assets and liabilities at fair value using a fair value hierarchy consisting of three broad levels that prioritize the inputs to valuation techniques giving the highest priority to readily available unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements) when market prices are not readily available or reliable. The categorization of a value determined for an investment within the hierarchy is based upon the pricing transparency of the investment and is not necessarily an indication of the risk associated with investing in it.
32


Table of Contents
SPDR SERIES TRUST
NOTES TO FINANCIAL STATEMENTS  (continued)
December 31, 2021 (Unaudited)

The three levels of the fair value hierarchy are as follows:
•   Level 1 – Unadjusted quoted prices in active markets for an identical asset or liability;
•   Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and
•   Level 3 – Unobservable inputs for the asset or liability, including the Committee’s assumptions used in determining the fair value of investments.
The value of each Fund’s investments, according to the fair value hierarchy as of December 31, 2021, is disclosed in each Fund’s respective Schedule of Investments.
Investment Transactions and Income Recognition
Investment transactions are accounted for on trade date for financial reporting purposes. Realized gains and losses from the sale or disposition of investments and foreign exchange transactions, if any, are determined using the identified cost method.
Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, or when the information becomes available, net of any foreign taxes withheld at source, if any. Non-cash dividends received in the form of stock, if any, are recorded as dividend income at fair value. Distributions received by the Funds may include a return of capital that is estimated by management. Such amounts are recorded as a reduction of the cost of investments or reclassified to capital gains.
Certain Funds invest in real estate investment trusts (“REITs”). REITs determine the tax character of their distributions annually and may characterize a portion of their distributions as a return of capital or capital gain. The Funds' policy is to record all REIT distributions initially as dividend income and re-designate a portion to return of capital or capital gain distributions at year end based on information provided by the REIT and/or SSGA Funds Management, Inc.’s (the “Adviser” or “SSGA FM”) estimates of such re-designations for which actual information has not yet been reported.

Expenses
Certain expenses, which are directly identifiable to a specific Fund, are applied to that Fund within the Trust. Other expenses which cannot be attributed to a specific Fund are allocated in such a manner as deemed equitable, taking into consideration the nature and type of expense and the relative net assets of the Fund within the Trust.
Foreign Taxes
The Funds may be subject to foreign taxes (a portion of which may be reclaimable) on income, stock dividends, realized and unrealized capital gains on investments or certain foreign currency transactions. Foreign taxes are recorded in accordance with SSGA FM's understanding of the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the Funds invest. These foreign taxes, if any, are paid by the Fund and are reflected in the Statements of Operations, if applicable. Foreign taxes payable or deferred as of December 31, 2021, if any, are disclosed in the Funds' Statements of Assets and Liabilities.
Equalization
The Funds follow the accounting practice known as “Equalization” by which a portion of the proceeds from sales and costs of reacquiring Fund shares, equivalent on a per share basis to the amount of distributable net investment income on the date of the transaction, is credited or charged to undistributed net investment income. As a result, undistributed net investment income per share is unaffected by sales or reacquisition of Fund shares. Amounts related to Equalization can be found on the Statements of Changes in Net Assets.
Distributions
Distributions from net investment income, if any, are declared and paid quarterly. Net realized capital gains, if any, are distributed annually. Dividends may be declared and paid more frequently or at any other times to improve Index tracking or to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). The amount and character of income and capital gains to be distributed are determined in accordance with applicable tax regulations which may differ from net investment income and realized gains recognized for U.S. GAAP purposes.
3.    Derivative Financial Instruments
Futures Contracts
The Funds may enter into futures contracts to meet the Funds’ objectives. A futures contract is a standardized, exchange-traded agreement to buy or sell a financial instrument at a set price on a future date. Upon entering into a futures contract, a Fund is required to deposit with the broker, cash or securities in an
34


Table of Contents
SPDR SERIES TRUST
NOTES TO FINANCIAL STATEMENTS  (continued)
December 31, 2021 (Unaudited)

amount equal to the minimum initial margin requirements of the clearing house. Securities deposited, if any, are designated on the Schedules of Investments and cash deposited, if any, is included in Net cash at broker on the Statements of Assets and Liabilities. Subsequent payments are made or received by the Fund equal to the daily change in the contract value, accumulated, exchange rates, and or other transactional fees. The accumulation of those payments are recorded as variation margin receivable or payable with a corresponding offset to unrealized gains or losses. The Funds recognize a realized gain or loss when the contract is closed.
Losses may arise if the value of a futures contract decreases due to unfavorable changes in the market rates or values of the underlying instrument during the term of the contract or if the counterparty does not perform under the contract. The use of futures contracts also involves the risk that the movements in the price of the futures contracts do not correlate with the movement of the assets underlying such contracts.
For the period ended December 31, 2021, the SPDR Dow Jones REIT ETF entered into futures contracts in order to gain exposure to the market for the cash and cash equivalents.
The following tables summarize the value of the Fund's derivative instruments as of December 31, 2021, and the related location in the accompanying Statements of Assets and Liabilities and Statements of Operations, presented by primary underlying risk exposure:

4.    Fees and Transactions with Affiliates
Advisory Fee
The Trust, on behalf of each Fund, has entered into an Investment Advisory Agreement with SSGA FM. For its advisory services to the Funds, facilities furnished, and expenses borne by the Adviser, each Fund pays the Adviser a fee (“Management/Advisory fee”) accrued daily and paid monthly, based on a percentage of each Fund’s average daily net assets as shown in the following table:
  Annual Rate
SPDR Dow Jones REIT ETF

From time to time, the Adviser may waive all or a portion of its fee. The Adviser has contractually agreed to waive a portion of its Management fee and/or reimburse expenses in an amount equal to any acquired fund fees and expenses (excluding holdings in acquired funds for cash management purposes, if any) for each Fund until October 31, 2022. This waiver and/or reimbursement does not provide for the recoupment by the Adviser of any amounts waived or reimbursed. This waiver and/or reimbursement may not be terminated prior to October 31, 2022 except with the approval of the Board.
The Adviser pays all the expenses of each Fund other than the Management fee, brokerage expenses, taxes, interest, fees and expenses of the Trust’s Trustees, who are not “interested persons” of the Trust, as defined in the 1940 Act (“Independent Trustees”) (including any Trustees’ counsel fees), acquired fund fees and expenses, litigation expenses, and other extraordinary expenses.

7.    Shareholder Transactions
Each Fund issues and redeems its shares, at NAV, by each Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”). Except when aggregated in Creation Units, shares of each Fund are not redeemable. Transactions in capital shares for each Fund are disclosed in detail in the Statements of Changes in Net Assets.
The consideration for the purchase of Creation Units of a Fund may consist of the in-kind deposit of a designated portfolio of securities and a specified amount of cash. Investors purchasing and redeeming Creation Units may pay a purchase transaction fee and a redemption transaction fee directly to the Trust and/or custodian, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. An additional variable fee may be charged for certain transactions. Such variable charges, if any, are included in “Other Capital” on the Statements of Changes in Net Assets.
8.    Income Tax Information
The Funds have qualified and intend to continue to qualify as regulated investment companies under Subchapter M of the Internal Revenue Code. Each Fund will not be subject to federal income taxes to the extent it distributes its taxable income, including any net realized capital gains, for each fiscal year. Therefore, no provision for federal income tax is required.
38


Table of Contents
SPDR SERIES TRUST
NOTES TO FINANCIAL STATEMENTS  (continued)
December 31, 2021 (Unaudited)

The Funds file federal and various state and local tax returns as required. No income tax returns are currently under examination. Generally, the federal returns are subject to examination by the Internal Revenue Service for a period of three years from date of filing, while the state returns may remain open for an additional year depending upon jurisdiction. As of June 30, 2021, SSGA FM has analyzed each Fund's tax positions taken on tax returns for all open years and does not believe there are any uncertain tax positions that would require recognition of a tax liability.
Distributions to shareholders are recorded on ex-dividend date. Income dividends and gain distributions are determined in accordance with income tax rules and regulations, which may differ from generally accepted accounting principles.
As of December 31, 2021, gross unrealized appreciation and gross unrealized depreciation of investments based on cost for federal income tax purposes were as follows:

9.    Securities Lending
Each Fund may lend securities to qualified broker-dealers or institutional investors. The loans are secured at all times by cash, cash equivalents or U.S. government securities in an amount at least equal to the market value of the securities loaned, plus accrued interest and dividends, determined on a daily basis and adjusted accordingly. The value of the collateral with respect to a loaned security may be temporarily more or less than the value of a security due to market fluctuations of securities values. With respect to each loan, if on any U.S. business day the aggregate market value of securities collateral plus cash collateral is less than the aggregate market value of the securities which are subject to the loan, the borrower will be notified to provide additional collateral on the next business day.
The Funds will regain record ownership of loaned securities to exercise certain beneficial rights; however, the Funds may bear the risk of delay in recovery of, or even loss of rights in the securities loaned should the borrower fail financially. In addition, a Fund will bear the risk of loss of any cash collateral that it may invest. Each Fund receives compensation for lending its securities from interest or dividends earned on the cash, cash equivalents or U.S. government securities held as collateral, net of fee rebates paid to the borrower and net of fees paid to State Street as the lending agent. Additionally, a Fund will receive a fee from the borrower for non-cash collateral equal to a percentage of the market value of the loaned securities.

affect the value of the Funds' investments more than if the Funds were more broadly diversified.
Credit Risk
A Fund may 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.
Market Risk
Each Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. Each Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, or other events could have a significant impact on a Fund and its investments.
An outbreak of a respiratory disease caused by a novel coronavirus (known as COVID-19) first detected in China in December 2019 has resulted in a global pandemic and major disruptions to economies and markets around the world, including the United States. Financial markets experienced and may continue to experience extreme volatility and severe losses, and trading in many instruments was and may continue to be disrupted as a result. Liquidity for many instruments was and may continue to be greatly reduced for periods of time. Some interest rates are very low and in some cases yields are negative. Governments and central banks, including the Federal Reserve in the United States, have taken extraordinary and unprecedented actions to support local and global economies and the financial markets. The impact of these measures, and whether they will be effective to mitigate the economic and market disruption, will not be known for some time. In addition, the outbreak of COVID-19, and measures taken to mitigate its effects, could result in disruptions to the services provided to a Fund by its service providers.
11.    Subsequent Events
Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

Expense Example
As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads), if applicable, on purchase payments, reinvested dividends, or other distributions and (2) ongoing costs, including advisory fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. It is based on an investment of $1,000 made at the beginning of the period shown and held for the entire period from July 1, 2021 to December 31, 2021.
The table below illustrates your Fund's cost in two ways:
Based on actual fund return ——This section helps you to estimate the actual expenses that you paid over the period. The “Ending Account Value” shown is derived from each Fund's actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the Fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period. To do so, 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 given for the Fund under the heading “Expenses Paid During Period”.
Based on hypothetical 5% return ——This section is intended to help you compare your Fund's costs with those of other mutual funds. It assumes that the Fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case, because the return used is not the Fund's actual return, the results do not apply to your investment. The example is useful in making comparisons because the U.S. Securities and Exchange Commission (the “SEC”) requires all mutual funds to calculate expenses based on a 5% return. You can assess your Fund's costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales load charges (loads). Therefore, the hypothetical 5% return section 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 transaction costs were included, your costs would have been higher.

Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Funds have adopted a liquidity risk management program (the "Program"). The Program's principal objectives include assessing, managing and periodically reviewing each Fund's liquidity risk, based on factors specific to the circumstances of the Fund. Liquidity risk is defined as the risk that a Fund could not meet redemption requests without significant dilution of remaining investors' interests in the Fund.
SSGA FM has been designated by the Board to administer the Funds' Program. During the fiscal year, SSGA FM provided the Board with a report addressing the operations of the Program and assessing its adequacy and the effectiveness of the Program's implementation for the period September 2020 through June 2021, including:
the Program supported each Fund's ability to honor redemption requests timely;
the Program supported SSGA FM's management of each Fund's liquidity profile, including during periods of market volatility and net redemptions;
no material liquidity issues were identified during the period;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage each Fund's liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to your Fund's prospectus for more information regarding the Fund's exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.
