The percentage shown for each investment category in the Schedule of Investments is based on net assets.
⁽¹⁾	Security exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities may be sold in certain transactions in reliance on an exemption from registration (normally to qualified institutional buyers). At December 31, 2021, the aggregate value of these securities is $1,316,247,315 or 51.8% of the Fund's net assets.
⁽²⁾	Variable rate security. The stated interest rate represents the rate in effect at December 31, 2021.

⁽³⁾	Step coupon security. Interest rate represents the rate in effect at December 31, 2021.
⁽⁴⁾	Weighted average fixed-rate coupon that changes/updates monthly. Rate shown is the rate at December 31, 2021.
⁽⁵⁾	Represents an investment in an issuer that may be deemed to be an affiliate effective March 1, 2021.
⁽⁶⁾	Security exempt from registration under Regulation S of the Securities Act of 1933, as amended, which exempts from registration securities offered and sold outside the United States. Security may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act of 1933, as amended. At December 31, 2021, the aggregate value of these securities is $10,075,926 or 0.4% of the Fund's net assets.
⁽⁷⁾	All or a portion of this security was on loan at December 31, 2021. The aggregate market value of securities on loan at December 31, 2021 was $14,593,125 and the total market value of the collateral received by the Fund was $15,061,180, comprised of cash of $10,077,908 and U.S. government and/or agencies securities of $4,983,272.
⁽⁸⁾	Security converts to variable rate after the indicated fixed-rate coupon period.

⁽¹¹⁾	Restricted security. Total market value of restricted securities amounts to $3,916,240, which represents 0.2% of the net assets of the Fund as of December 31, 2021.
⁽¹²⁾	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.
⁽¹³⁾	This Senior Loan will settle after December 31, 2021, at which time the interest rate will be determined.
⁽¹⁴⁾	Affiliated investment company, available to Calvert portfolios and funds, which invests in high quality, U.S. dollar denominated money market instruments. The rate shown is the annualized seven-day yield as of December 31, 2021.
⁽¹⁵⁾	Represents investment of cash collateral received in connection with securities lending.

U.S. generally accepted accounting principles (U.S. GAAP) establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

Level 1 - quoted prices in active markets for identical securities

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

Level 3 - significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table summarizes the market value of the Fund's holdings as of December 31, 2021, based on the inputs used to value them:
