CUSIP No.      224916106 SCHEDULE 13D/A Page 4 of 6 Pages

            This Amendment No. 4 amends and supplements the statement on Schedule 13D filed with the Securities and Exchange Commission (the "SEC") on February 14, 2017 (the "Original Schedule 13D"). As amended by Amendment No. 1 filed 8/18/17, Amendment No. 2 filed 8/18/17, and Amendment No. 3 filed 11/3/17. With respect to the shares ("Shares") of common stock, par value $0.001 per share, of Credit Suisse Asset Management Income Fund, Inc.(the "Issuer"). This Amendment No. 4 amends Items 3 and 5 as set forth below.

Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

            Funds for the purchase of the Common Shares were derived from the subscription proceeds from investors in the Saba Entities and the capital appreciation thereon and margin account borrowings made in the ordinary course of business. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account, which may exist from time to time. Since other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Shares reported herein. A total of $10,752,171 was paid to acquire the Common Shares reported herein.
