⁽¹⁵⁾  Senior floating-rate loans (Senior Loans) often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. However, Senior Loans will typically have an expected average life of approximately two to four years. Senior Loans typically have rates of interest which are redetermined periodically by reference to a base lending rate, plus a spread. These base lending rates are primarily the London Interbank Offered Rate (“LIBOR”) and secondarily, the prime rate offered by one or more major United States banks (the “Prime Rate”). Base lending rates may be subject to a floor, or minimum rate. Senior Loans are generally subject to contractual restrictions that must be satisfied before they can be bought or sold.

⁽¹⁶⁾  This Senior Loan will settle after October 31, 2021, at which time the interest rate will be determined.

⁽¹⁷⁾  Unfunded or partially unfunded loan commitments. The stated interest rate reflects the weighted average of the reference rate and spread for the funded portion, if any, and the commitment fees on the portion of the loan that is unfunded. At October 31, 2021, the total value of unfunded loan commitments is $232,022. See Note 1F for description.

* If the Portfolio is the seller of credit protection, the notional amount is the maximum potential amount of future payments the Portfolio could be required to make if a credit event, as defined in the credit default swap agreement, were to occur. At October 31, 2021, such maximum potential amount for all open credit default swaps in which the Portfolio is the seller was $9,000,000.

** The contract annual fixed rate represents the fixed rate of interest received by the Portfolio (as a seller of protection) on the notional amount of the credit default swap contract.

*** Current market annual fixed rates, utilized in determining the net unrealized appreciation or depreciation as of period end, serve as an indicator of the market’s perception of the current status of the payment/performance risk associated with the credit derivative. The current market annual fixed rate of a particular reference entity reflects the cost, as quoted by the pricing vendor, of selling protection against default of that entity as of period end and may include upfront payments required to be made to enter into the agreement. The higher the fixed rate, the greater the market perceived risk of a credit event involving the reference entity. A rate identified as “Defaulted” indicates a credit event has occurred for the reference entity.

⁽¹⁾  Upfront payment is exchanged with the counterparty as a result of the standardized trading coupon.

1  Significant Accounting Policies

High Income Opportunities Portfolio (the Portfolio) is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a diversified, open-end management investment company. The Portfolio’s investment objective is to provide a high level of current income. The Portfolio also seeks growth of capital as a secondary investment objective. The Declaration of Trust permits the Trustees to issue interests in the Portfolio. At October 31, 2021, Eaton Vance High Income Opportunities Fund and Eaton Vance Floating-Rate & High Income Fund held an interest of 74.7% and 25.3%, respectively, in the Portfolio.

The following is a summary of significant accounting policies of the Portfolio. The policies are in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP). The Portfolio is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946.

A  Investment Valuation — The following methodologies are used to determine the market value or fair value of investments.

Debt Obligations. Debt obligations are generally valued on the basis of valuations provided by third party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and ask prices, broker/dealer quotations, prices or yields of securities with similar characteristics, interest rates, anticipated prepayments, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. Short-term debt obligations purchased with a remaining maturity of sixty days or less for which a valuation from a third party pricing service is not readily available may be valued at amortized cost, which approximates fair value.

Senior Floating-Rate Loans. Interests in senior floating-rate loans (Senior Loans) for which reliable market quotations are readily available are valued generally at the average mean of bid and ask quotations obtained from a third party pricing service. Other Senior Loans are valued at fair value by the investment adviser under procedures approved by the Trustees. In fair valuing a Senior Loan, the investment adviser utilizes one or more of the valuation techniques described in (i) through (iii) below to assess the likelihood that the borrower will make a full repayment of the loan underlying such Senior Loan relative to yields on other Senior Loans issued by companies of comparable credit quality. If the investment adviser believes that there is a reasonable likelihood of full repayment, the investment adviser will determine fair value using a matrix pricing approach that considers the yield on the Senior Loan. If the investment adviser believes there is not a reasonable likelihood of full repayment, the investment adviser will determine fair value using analyses that include, but are not limited to: (i) a comparison of the value of the borrower’s outstanding equity and debt to that of comparable public companies; (ii) a discounted cash flow analysis; or (iii) when the investment adviser believes it is likely that a borrower will be liquidated or sold, an analysis of the terms of such liquidation or sale. In certain cases, the investment adviser will use a combination of analytical methods to determine fair value, such as when only a portion of a borrower’s assets are likely to be sold. In conducting its assessment and analyses for purposes of determining fair value of a Senior Loan, the investment adviser will use its discretion and judgment in considering and appraising relevant factors. Fair value determinations are made by the portfolio managers of the Portfolio based on information available to such managers. The portfolio managers of other funds managed by the investment adviser that invest in Senior Loans may not possess the same information about a Senior Loan borrower as the portfolio managers of the Portfolio. At times, the fair value of a Senior Loan determined by the portfolio managers of other funds managed by the investment adviser that invest in Senior Loans may vary from the fair value of the same Senior Loan determined by the portfolio managers of the Portfolio. The fair value of each Senior Loan is periodically reviewed and approved by the investment adviser’s Valuation Committee and by the Trustees based upon procedures approved by the Trustees. Junior Loans (i.e., subordinated loans and second lien loans) are valued in the same manner as Senior Loans.

Equity Securities. Equity securities listed on a U.S. securities exchange generally are valued at the last sale or closing price on the day of valuation or, if no sales took place on such date, at the mean between the closing bid and ask prices on the exchange where such securities are principally traded. Equity securities listed on the NASDAQ National Market System are valued at the NASDAQ official closing price. Unlisted or listed securities for which closing sales prices or closing quotations are not available are valued at the mean between the latest available bid and ask prices or, in the case of preferred equity securities that are not listed or traded in the over-the-counter market, by a third party pricing service that uses various techniques that consider factors including, but not limited to, prices or yields of securities with similar characteristics, benchmark yields, broker/dealer quotes, quotes of underlying common stock, issuer spreads, as well as industry and economic events.

Derivatives. Forward foreign currency exchange contracts are generally valued at the mean of the average bid and average ask prices that are reported by currency dealers to a third party pricing service at the valuation time. Such third party pricing service valuations are supplied for specific settlement periods and the Portfolio’s forward foreign currency exchange contracts are valued at an interpolated rate between the closest preceding and subsequent settlement period reported by the third party pricing service. Swaps are normally valued using valuations provided by a third party pricing service. Such pricing service valuations are based on the present value of fixed and projected floating rate cash flows over the term of the swap contract, and in the case of credit default swaps, based on credit spread quotations obtained from broker/dealers and expected default recovery rates determined by the pricing service using proprietary models. Future cash flows on swaps are discounted to their present value using swap rates provided by electronic data services or by broker/dealers.

Foreign Securities and Currencies. Foreign securities and currencies are valued in U.S. dollars, based on foreign currency exchange rate quotations supplied by a third party pricing service. The pricing service uses a proprietary model to determine the exchange rate. Inputs to the model include reported trades and implied bid/ask spreads.

Affiliated Fund. The Portfolio may invest in Eaton Vance Cash Reserves Fund, LLC (Cash Reserves Fund), an affiliated investment company managed by Eaton Vance Management (EVM). While Cash Reserves Fund is not a registered money market mutual fund, it conducts all of its investment activities in accordance with the requirements of Rule 2a-7 under the 1940 Act. Investments in Cash Reserves Fund are valued at the closing net asset value per unit on the valuation day. Cash Reserves Fund generally values its investment securities based on available market quotations provided by a third party pricing service.

Fair Valuation. Investments for which valuations or market quotations are not readily available or are deemed unreliable are valued at fair value using methods determined in good faith by or at the direction of the Trustees of the Portfolio in a manner that most fairly reflects the security’s “fair value”, which is the amount that the Portfolio might reasonably expect to receive for the security upon its current sale in the ordinary course. Each such determination is based on a consideration of relevant factors, which are likely to vary from one pricing context to another. These factors may include, but are not limited to, the type of security, the existence of any contractual restrictions on the security’s disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies or entities, quotations or relevant information obtained from broker/dealers or other market participants, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company’s or entity’s financial statements, and an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

B  Investment Transactions — Investment transactions for financial statement purposes are accounted for on a trade date basis. Realized gains and losses on investments sold are determined on the basis of identified cost.

C  Income — Interest income is recorded on the basis of interest accrued, adjusted for amortization of premium or accretion of discount. Fees associated with loan amendments are recognized immediately. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. Withholding taxes on foreign dividends have been provided for in accordance with the Portfolio’s understanding of the applicable countries’ tax rules and rates.

D  Federal Taxes — The Portfolio has elected to be treated as a partnership for federal tax purposes. No provision is made by the Portfolio for federal or state taxes on any taxable income of the Portfolio because each investor in the Portfolio is ultimately responsible for the payment of any taxes on its share of taxable income. Since at least one of the Portfolio’s investors is a regulated investment company that invests all or substantially all of its assets in the Portfolio, the Portfolio normally must satisfy the applicable source of income and diversification requirements (under the Internal Revenue Code) in order for its investors to satisfy them. The Portfolio will allocate, at least annually among its investors, each investor’s distributive share of the Portfolio’s net investment income, net realized capital gains and losses and any other items of income, gain, loss, deduction or credit.

As of October 31, 2021, the Portfolio had no uncertain tax positions that would require financial statement recognition, de-recognition, or disclosure. The Portfolio files a U.S. federal income tax return annually after its fiscal year-end, which is subject to examination by the Internal Revenue Service for a period of three years from the date of filing.

E  Foreign Currency Translation — Investment valuations, other assets, and liabilities initially expressed in foreign currencies are translated each business day into U.S. dollars based upon current exchange rates. Purchases and sales of foreign investment securities and income and expenses denominated in foreign currencies are translated into U.S. dollars based upon currency exchange rates in effect on the respective dates of such transactions. Recognized gains or losses on investment transactions attributable to changes in foreign currency exchange rates are recorded for financial statement purposes as net realized gains and losses on investments. That portion of unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed.

F  Unfunded Loan Commitments — The Portfolio may enter into certain loan agreements all or a portion of which may be unfunded. The Portfolio is obligated to fund these commitments at the borrower’s discretion. These commitments are disclosed in the accompanying Portfolio of Investments. At October 31, 2021, the Portfolio had sufficient cash and/or securities to cover these commitments.

G  Use of Estimates — The preparation of the financial statements in conformity with 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 income and expense during the reporting period. Actual results could differ from those estimates.

H  Indemnifications — Under the Portfolio’s organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the Portfolio. Under Massachusetts law, if certain conditions prevail, interestholders in the Portfolio could be deemed to have personal liability for the obligations of the Portfolio. However, the Portfolio’s Declaration of Trust contains an express disclaimer of liability on the part of Portfolio interestholders. Additionally, in the normal course of business, the Portfolio enters into agreements with service providers that may contain indemnification clauses. The Portfolio’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Portfolio that have not yet occurred.

I  Forward Foreign Currency Exchange Contracts — The Portfolio may enter into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until such time as the contracts have been closed. Risks may arise upon entering these contracts from the potential inability of counterparties to meet the terms of their contracts and from movements in the value of a foreign currency relative to the U.S. dollar.

Notes to Financial Statements — continued

J  When-Issued Securities and Delayed Delivery Transactions — The Portfolio may purchase securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. At the time the transaction is negotiated, the price of the security that will be delivered is fixed. The Portfolio maintains cash and/or security positions for these commitments such that sufficient liquid assets will be available to make payments upon settlement. Securities purchased on a delayed delivery or when-issued basis are marked-to-market daily and begin earning interest on settlement date. Such security purchases are subject to the risk that when delivered they will be worth less than the agreed upon payment price. Losses may also arise if the counterparty does not perform under the contract.

K  Credit Default Swaps — Swap contracts are privately negotiated agreements between the Portfolio and a counterparty. Certain swap contracts may be centrally cleared (“centrally cleared swaps”), whereby all payments made or received by the Portfolio pursuant to the contract are with a central clearing party (CCP) rather than the original counterparty. The CCP guarantees the performance of the original parties to the contract. Upon entering into centrally cleared swaps, the Portfolio is required to deposit with the CCP, either in cash or securities, an amount of initial margin determined by the CCP, which is subject to adjustment. When the Portfolio is the buyer of a credit default swap contract, the Portfolio is entitled to receive the par (or other agreed-upon) value of a referenced debt obligation (or basket of debt obligations) from the counterparty (or CCP in the case of a centrally cleared swap) to the contract if a credit event by a third party, such as a U.S. or foreign corporate issuer or sovereign issuer, on the debt obligation occurs. In return, the Portfolio pays the counterparty a periodic stream of payments over the term of the contract provided that no credit event has occurred. If no credit event occurs, the Portfolio would have spent the stream of payments and received no proceeds from the contract. When the Portfolio is the seller of a credit default swap contract, it receives the stream of payments, but is obligated to pay to the buyer of the protection an amount up to the notional amount of the swap and in certain instances take delivery of securities of the reference entity upon the occurrence of a credit event, as defined under the terms of that particular swap agreement. Credit events are contract specific but may include bankruptcy, failure to pay, restructuring, obligation acceleration and repudiation/moratorium. If the Portfolio is a seller of protection and a credit event occurs, the maximum potential amount of future payments that the Portfolio could be required to make would be an amount equal to the notional amount of the agreement. This potential amount would be partially offset by any recovery value of the respective referenced obligation, or net amount received from the settlement of a buy protection credit default swap agreement entered into by the Portfolio for the same referenced obligation. As the seller, the Portfolio may create economic leverage to its portfolio because, in addition to its total net assets, the Portfolio is subject to investment exposure on the notional amount of the swap. The interest fee paid or received on the swap contract, which is based on a specified interest rate on a fixed notional amount, is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as realized gain upon receipt or realized loss upon payment. The Portfolio also records an increase or decrease to unrealized appreciation (depreciation) in an amount equal to the daily valuation. For centrally cleared swaps, the daily change in valuation is recorded as a receivable or payable for variation margin and settled in cash with the CCP daily. All upfront payments and receipts, if any, are amortized over the life of the swap contract as realized gains or losses. Those upfront payments or receipts for non-centrally cleared swaps are recorded as other assets or other liabilities, respectively, net of amortization. For financial reporting purposes, unamortized upfront payments or receipts, if any, are netted with unrealized appreciation or depreciation on swap contracts to determine the market value of swaps as presented in Notes 6 and 9. The Portfolio segregates assets in the form of cash or liquid securities in an amount equal to the notional amount of the credit default swaps of which it is the seller. The Portfolio segregates assets in the form of cash or liquid securities in an amount equal to any unrealized depreciation of the credit default swaps of which it is the buyer, marked-to market on a daily basis. These transactions involve certain risks, including the risk that the seller may be unable to fulfill the transaction. In the case of centrally cleared swaps, counterparty risk is minimal due to protections provided by the CCP.

2  Investment Adviser Fee and Other Transactions with Affiliates

The investment adviser fee is earned by Boston Management and Research (BMR) as compensation for investment advisory services rendered to the Portfolio. On March 1, 2021, Morgan Stanley acquired Eaton Vance Corp. (the “Transaction”) and BMR became an indirect, wholly-owned subsidiary of Morgan Stanley. In connection with the Transaction, the Portfolio entered into a new investment advisory agreement (the “New Agreement”) with BMR, which took effect on March 1, 2021. Pursuant to the New Agreement (and the Portfolio’s investment advisory agreement with BMR in effect prior to March 1, 2021), the investment adviser fee is based upon a percentage of total daily net assets plus a percentage of total daily gross income as follows and is payable monthly:

Total Daily Net Assets	Annual Asset Rate			Daily Income Rate
Up to $500 million		0.300	%		3.00	%
$500 million but less than $1 billion		0.275	%		2.75	%
$1 billion but less than $1.5 billion		0.250	%		2.50	%
$1.5 billion but less than $2 billion		0.225	%		2.25	%
$2 billion but less than $3 billion		0.200	%		2.00	%
$3 billion and over		0.175	%		1.75	%

For the year ended October 31, 2021, the Portfolio’s investment adviser fee amounted to $4,224,498 or 0.44% of the Portfolio’s average daily net assets.

Pursuant to an investment sub-advisory agreement, BMR has delegated a portion of the investment management of the Portfolio to Eaton Vance Advisers International Ltd. (EVAIL), an affiliate of BMR. In connection with the Transaction, BMR entered into a new sub-advisory agreement with EVAIL, which took effect on March 1, 2021. BMR pays EVAIL a portion of its investment adviser fee for sub-advisory services provided to the Portfolio. The Portfolio may invest its cash in Cash Reserves Fund. EVM does not currently receive a fee for advisory services provided to Cash Reserves Fund.

Trustees and officers of the Portfolio who are members of EVM’s or BMR’s organizations receive remuneration for their services to the Portfolio out of the investment adviser fee. Trustees of the Portfolio who are not affiliated with the investment adviser may elect to defer receipt of all or a percentage of their annual fees in accordance with the terms of the Trustees Deferred Compensation Plan. For the year ended October 31, 2021, no significant amounts have been deferred. Certain officers and Trustees of the Portfolio are officers of the above organizations.

6  Financial Instruments

The Portfolio may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities. These financial instruments may include forward foreign currency exchange contracts and swap contracts and may involve, to a varying degree, elements of risk in excess of the amounts recognized for financial statement purposes. The notional or contractual amounts of these instruments represent the investment the Portfolio has in particular classes of financial instruments and do not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered. A summary of obligations under these financial instruments at October 31, 2021 is included in the Portfolio of Investments. At October 31, 2021, the Portfolio had sufficient cash and/or securities to cover commitments under these contracts.

In the normal course of pursuing its investment objectives, the Portfolio is subject to the following risks:

Credit Risk: The Portfolio enters into credit default swap contracts to manage its credit risk, to gain exposure to a credit in which it may otherwise invest, or to enhance total return.

Foreign Exchange Risk: The Portfolio holds foreign currency denominated investments. The value of these investments and related receivables and payables may change due to future changes in foreign currency exchange rates. To hedge against this risk, the Portfolio enters into forward foreign currency exchange contracts.

The Portfolio enters into forward foreign currency exchange contracts that may contain provisions whereby the counterparty may terminate the contract under certain conditions, including but not limited to a decline in the Portfolio’s net assets below a certain level over a certain period of time, which would trigger a payment by the Portfolio for those derivatives in a liability position. At October 31, 2021, the Portfolio had no open derivatives with credit-related contingent features in a net liability position.

The over-the-counter (OTC) derivatives in which the Portfolio invests are subject to the risk that the counterparty to the contract fails to perform its obligations under the contract. To mitigate this risk, the Portfolio has entered into an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement with substantially all its derivative counterparties. An ISDA Master Agreement is a bilateral agreement between the Portfolio and a counterparty that governs certain OTC derivatives and typically contains, among other things, set-off provisions in the event of a default and/or termination event as defined under the relevant ISDA Master Agreement. Under an ISDA Master Agreement, the Portfolio may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy or insolvency. Certain ISDA Master Agreements allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event the Portfolio’s net assets decline by a stated percentage or the Portfolio fails to meet the terms of its ISDA Master Agreements, which would cause the counterparty to accelerate payment by the Portfolio of any net liability owed to it.

The collateral requirements for derivatives traded under an ISDA Master Agreement are governed by a Credit Support Annex to the ISDA Master Agreement. Collateral requirements are determined at the close of business each day and are typically based on changes in market values for each transaction under an ISDA Master Agreement and netted into one amount for such agreement. Generally, the amount of collateral due from or to a counterparty is subject to a minimum transfer threshold amount before a transfer is required, which may vary by counterparty. Collateral pledged for the benefit of the Portfolio and/or counterparty is held in segregated accounts by the Portfolio’s custodian and cannot be sold, re-pledged, assigned or otherwise used while pledged. The portion of such collateral representing cash, if any, is reflected as deposits for derivatives collateral and, in the case of cash pledged by a counterparty for the benefit of the Portfolio, a corresponding liability on the Statement of Assets and Liabilities. Securities pledged by the Portfolio as collateral, if any, are identified as such in the Portfolio of Investments.

The fair value of open derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) by risk exposure at October 31, 2021 was as follows:

		Fair Value
Risk	Derivative	Asset Derivative			Liability Derivative
Credit	Swap contracts (centrally cleared)	$	847,123	(1)	$	—
Foreign Exchange	Forward foreign currency exchange contracts		51,299	(2)		—
Derivatives not subject to master netting or similar agreements		$	847,123		$	—
Total Derivatives subject to master netting or similar agreements		$	51,299		$	—

⁽¹⁾  Only the current day’s variation margin on open centrally cleared swap contracts is reported within the Statement of Assets and Liabilities as Receivable or Payable for variation margin on open centrally cleared swap contracts, as applicable.

⁽²⁾  Statement of Assets and Liabilities location: Receivable for open forward foreign currency exchange contracts.

Notes to Financial Statements — continued

The Portfolio’s derivative assets at fair value by type, which are reported gross in the Statement of Assets and Liabilities, are presented in the table above. The following table presents the Portfolio’s derivative assets by counterparty, net of amounts available for offset under a master netting agreement and net of the related collateral received by the Portfolio for such assets as of October 31, 2021.

Counterparty	Derivative Assets Subject to Master Netting Agreement		Derivatives Available for Offset		Non-cash Collateral Received(a)		Cash Collateral Received(a)			Net Amount of Derivative Assets(b)
State Street Bank and Trust Company	$	51,299	$	—	$	—	$	(51,299	)	$	—
	$	51,299	$	—	$	—	$	(51,299	)	$	—

^(a)  In some instances, the total collateral received and/or pledged may be more than the amount shown due to overcollateralization.

^(b)  Net amount represents the net amount due from the counterparty in the event of default.

The effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) on the Statement of Operations by risk exposure for the year ended October 31, 2021 was as follows:

Risk	Derivative	Realized Gain (Loss) on Derivatives Recognized in Income(1)			Change in Unrealized Appreciation (Depreciation) on Derivatives Recognized in Income(2)
Credit	Swap contracts (centrally cleared)	$	63,853		$	4,385
Foreign Exchange	Forward foreign currency exchange contracts		(239,642	)		(223,104	)

⁽¹⁾  Statement of Operations location: Net realized gain (loss) – Swap contracts and Forward foreign currency exchange contracts, respectively.

⁽²⁾  Statement of Operations location: Change in unrealized appreciation (depreciation) – Swap contracts and Forward foreign currency exchange contracts, respectively.

The average notional amounts of derivative contracts outstanding during the year ended October 31, 2021, which are indicative of the volume of these derivative types, were approximately as follows:

Forward Foreign Currency Exchange Contracts		Swap Contracts
	$25,986,000*	$	3,462,000

* The average notional amount of forward foreign currency exchange contracts is based on the absolute value of notional amounts of currency purchased and currency sold.

7  Line of Credit

The Portfolio participates with other portfolios and funds managed by EVM and its affiliates in an $800 million unsecured line of credit agreement with a group of banks, which is in effect through October 25, 2022. Borrowings are made by the Portfolio solely for temporary purposes related to redemptions and other short-term cash needs. Interest is charged to the Portfolio based on its borrowings at an amount above either the Secured Overnight Financing Rate (SOFR) or Federal Funds rate. In addition, a fee computed at an annual rate of 0.15% on the daily unused portion of the line of credit is allocated among the participating portfolios and funds at the end of each quarter. In connection with the renewal of the agreement in October 2021, an arrangement fee totaling $150,000 was incurred that was allocated to the participating portfolios and funds. Because the line of credit is not available exclusively to the Portfolio, it may be unable to borrow some or all of its requested amounts at any particular time. The Portfolio did not have any significant borrowings or allocated fees during the year ended October 31, 2021.

8  Investments in Affiliated Funds

At October 31, 2021, the value of the Portfolio’s investment in affiliated funds was $43,702,301, which represents 4.4% of the Portfolio’s net assets. Transactions in affiliated funds by the Portfolio for the year ended October 31, 2021 were as follows:

Name	Value, beginning of period		Purchases		Sales proceeds			Net realized gain (loss)		Change in unrealized appreciation (depreciation)		Value, end of period		Dividend income		Units, end of period
Short-Term Investments
Eaton Vance Cash Reserves Fund, LLC	$	9,344,574	$	438,656,084	$	(404,298,695	)	$	338	$	—	$	43,702,301	$	22,465		43,702,301

9  Fair Value Measurements

Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

• Level 1 – quoted prices in active markets for identical investments

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

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

In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

At October 31, 2021, the hierarchy of inputs used in valuing the Portfolio’s investments and open derivative instruments, which are carried at value, were as follows:

Asset Description	Level 1		Level 2		Level 3*		Total
Asset-Backed Securities	$	—	$	5,971,485	$	—	$	5,971,485
Commercial Mortgage-Backed Securities		—		3,052,744		—		3,052,744
Common Stocks		27,717,826		5,428,920		8,166,894		41,313,640
Convertible Bonds		—		2,564,230		—		2,564,230
Convertible Preferred Stocks		3,026,895		—		0		3,026,895
Corporate Bonds		—		826,299,501		—		826,299,501
Preferred Stocks		4,631,123		—		—		4,631,123
Senior Floating-Rate Loans (Less Unfunded Loan Commitments)		—		54,840,541		—		54,840,541
Miscellaneous		—		35,140		10,053,840		10,088,980
Short-Term Investments		—		43,702,301		—		43,702,301
Total Investments	$	35,375,844	$	941,894,862	$	18,220,734	$	995,491,440
Forward Foreign Currency Exchange Contracts	$	—	$	51,299	$	—	$	51,299
Swap Contracts		—		847,123		—		847,123
Total	$	35,375,844	$	942,793,284	$	18,220,734	$	996,389,862

* None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Portfolio.

Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the year ended October 31, 2021 is not presented.

10  Risks and Uncertainties

Pandemic Risk

An outbreak of respiratory disease caused by a novel coronavirus was first detected in China in late 2019 and subsequently spread internationally. This coronavirus has resulted in closing borders, enhanced health screenings, changes to healthcare service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty. Health crises caused by outbreaks, such as the coronavirus outbreak, may exacerbate other pre-existing political, social and economic risks and disrupt normal market conditions and operations. The impact of this outbreak has negatively affected the worldwide economy, the economies of individual countries, individual companies, and the market in general, and may continue to do so in significant and unforeseen ways, as may other epidemics and pandemics that may arise in the future. Any such impact could adversely affect the Portfolio’s performance, or the performance of the securities in which the Portfolio invests.

Report of Independent Registered Public Accounting Firm

To the Trustees and Investors of High Income Opportunities Portfolio:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of High Income Opportunities Portfolio (the “Portfolio”), including the portfolio of investments, as of October 31, 2021, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Portfolio as of October 31, 2021, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Portfolio’s management. Our responsibility is to express an opinion on the Portfolio’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Portfolio in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Portfolio is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Portfolio’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities and senior loans owned as of October 31, 2021, by correspondence with the custodian, brokers, and selling or agent banks; when replies were not received from brokers and selling or agent banks, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Liquidity Risk Management Program

The Fund has implemented a written liquidity risk management program (Program) and related procedures to manage its liquidity in accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (Liquidity Rule). The Liquidity Rule defines “liquidity risk” as the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of the remaining investors’ interests in the fund. The Fund’s Board of Trustees/Directors has designated the investment adviser to serve as the administrator of the Program and the related procedures. The administrator has established a Liquidity Risk Management Oversight Committee (Committee) to perform the functions necessary to administer the Program. As part of the Program, the administrator is responsible for identifying illiquid investments and categorizing the relative liquidity of the Fund’s investments in accordance with the Liquidity Rule. Under the Program, the administrator assesses, manages, and periodically reviews the Fund’s liquidity risk, and is responsible for making certain reports to the Fund’s Board of Trustees/Directors and the Securities and Exchange Commission (SEC) regarding the liquidity of the Fund’s investments, and to notify the Board of Trustees/Directors and the SEC of certain liquidity events specified in the Liquidity Rule. The liquidity of the Fund’s portfolio investments is determined based on a number of factors including, but not limited to, relevant market, trading and investment-specific considerations under the Program.

At a meeting of the Fund’s Board of Trustees/Directors on June 8, 2021, the Committee provided a written report to the Fund’s Board of Trustees/Directors pertaining to the operation, adequacy, and effectiveness of implementation of the Program, as well as the operation of the highly liquid investment minimum (if applicable) for the period January 1, 2020 through December 31, 2020 (Review Period). The Program operated effectively during the Review Period, supporting the administrator’s ability to assess, manage and monitor Fund liquidity risk, including during periods of market volatility and net redemptions. During the Review Period, the Fund met redemption requests on a timely basis.

There can be no assurance that the Program will achieve its objectives in the future. Please refer to the 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.

IMPORTANT NOTICES

Delivery of Shareholder Documents.  The Securities and Exchange Commission (SEC) permits funds to deliver only one copy of shareholder documents, including prospectuses, proxy statements and shareholder reports, to fund investors with multiple accounts at the same residential or post office box address. This practice is often called “householding” and it helps eliminate duplicate mailings to shareholders. Eaton Vance, or your financial intermediary, may household the mailing of your documents indefinitely unless you instruct Eaton Vance, or your financial intermediary, otherwise. If you would prefer that your Eaton Vance documents not be householded, please contact Eaton Vance at 1-800-262-1122, or contact your financial intermediary. Your instructions that householding not apply to delivery of your Eaton Vance documents will typically be effective within 30 days of receipt by Eaton Vance or your financial intermediary.

Portfolio Holdings.  Each Eaton Vance Fund and its underlying Portfolio(s) (if applicable) files a schedule of portfolio holdings on Part F to Form N-PORT with the SEC. Certain information filed on Form N-PORT may be viewed on the Eaton Vance website at www.eatonvance.com, by calling Eaton Vance at 1-800-262-1122 or in the EDGAR database on the SEC’s website at www.sec.gov.

Proxy Voting.  From time to time, funds are required to vote proxies related to the securities held by the funds. The Eaton Vance Funds or their underlying Portfolios (if applicable) vote proxies according to a set of policies and procedures approved by the Funds’ and Portfolios’ Boards. You may obtain a description of these policies and procedures and information on how the Funds or Portfolios voted proxies relating to portfolio securities during the most recent 12-month period ended June 30, without charge, upon request, by calling 1-800-262-1122 and by accessing the SEC’s website at www.sec.gov.

Item 4. Principal Accountant Fees and Services

(a)-(d)

The following table presents the aggregate fees billed to the registrant for the registrant’s fiscal years ended October 31, 2020 and October 31, 2021 by the registrant’s principal accountant, Deloitte & Touche LLP (“D&T”), for professional services rendered for the audit of the registrant’s annual financial statements and fees billed for other services rendered by D&T during such periods.

Fiscal Years Ended	10/31/20		10/31/21
Audit Fees	$	79,300	$	79,661
Audit-Related Fees(1)	$	0	$	0
Tax Fees(2)	$	16,326	$	16,676
All Other Fees(3)	$	0	$	0
Total	$	95,626	$	96,337

⁽¹⁾  Audit-related fees consist of the aggregate fees billed for assurance and related services that are reasonably related to the performance of the audit of the registrant’s financial statements and are not reported under the category of audit fees.

⁽²⁾  Tax fees consist of the aggregate fees billed for professional services rendered by the principal accountant relating to tax compliance, tax advice, and tax planning and specifically include fees for tax return preparation and other related tax compliance/planning matters.

⁽³⁾  All other fees consist of the aggregate fees billed for products and services provided by the principal accountant other than audit, audit-related, and tax services.

(e)(1) The registrant’s audit committee has adopted policies and procedures relating to the pre-approval of services provided by the registrant’s principal accountant (the “Pre-Approval Policies”). The Pre-Approval Policies establish a framework intended to assist the audit committee in the proper discharge of its pre-approval responsibilities. As a general matter, the Pre-Approval Policies (i) specify certain types of audit, audit-related, tax, and other services determined to be pre-approved by the audit committee; and (ii) delineate specific procedures governing the mechanics of the pre-approval process, including the approval and monitoring of audit and non-audit service fees. Unless a service is specifically pre-approved under the Pre-Approval Policies, it must be separately pre-approved by the Audit Committee.

The Pre-Approval Policies and the types of audit and non-audit services pre-approved therein must be reviewed and ratified by the registrant’s audit committee at least annually. The registrant’s audit committee maintains full responsibility for the appointment, compensation, and oversight of the work of the registrant’s principal accountant.

(e)(2) No services described in paragraphs (b)-(d) above were approved by the registrant’s audit committee pursuant to the “de minimis exception” set forth in Rule 2-01 (c)(7)(i)(C) of Regulation S-X.

(f) Not applicable.

(g) The following table presents (i) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed to the registrant by D&T for the registrant’s fiscal years ended October 31, 2020 and October 31, 2021; and (ii) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed to the Eaton Vance organization by D&T for the same time periods.

Fiscal Years Ended	10/31/20		10/31/21
Registrant	$	16,326	$	16,676
Eaton Vance(1)	$	51,800	$	51,800

⁽¹⁾ Certain entities that provide ongoing services to the registrant are subsidiaries of Morgan Stanley.

(h) The registrant’s audit committee has considered whether the provision by the registrant’s principal accountant of non-audit services to the registrant’s investment adviser and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant that were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X is compatible with maintaining the principal accountant’s independence.
