⁽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 $448,488,164 or 44.8% of the Fund's net assets.
⁽²⁾	Variable rate security. The stated interest rate represents the rate in effect at December 31, 2021.

⁽³⁾	Represents an investment in an issuer that may be deemed to be an affiliate effective March 1, 2021.
⁽⁴⁾	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 $3,450,874 and the total market value of the collateral received by the Fund was $3,569,581, comprised of cash of $926,323 and U.S. government and/or agencies securities of $2,643,258.
⁽⁵⁾	Security converts to variable rate after the indicated fixed-rate coupon period.
⁽⁶⁾	May be deemed to be an affiliated company.
⁽⁷⁾	Restricted security. Total market value of restricted securities amounts to $979,060, which represents 0.1% of the net assets of the Fund as of December 31, 2021.
⁽⁸⁾	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.
⁽⁹⁾	This Senior Loan will settle after December 31, 2021, at which time the interest rate will be determined.
⁽¹⁰⁾	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.
⁽¹¹⁾	Security is exempt from registration under Section 4(2) of the Securities Act of 1933, as amended. Such securities may be sold in transactions exempt from registration only to dealers in that program or other “accredited investors”. At December 31, 2021, the aggregate value of these securities is $24,997,692 representing 2.5% of the Fund’s net assets.
⁽¹²⁾	Rate shown is the discount rate at date of purchase.
⁽¹³⁾	Represents investment of cash collateral received in connection with securities lending.
