(c) Level of reserve. The reserve must be built up to and maintained at a level determined by HUD to be sufficient to meet projected requirements. Should the reserve reach that level, the amount of the deposit to the reserve may be reduced with the approval of HUD.
(d) Administration of reserve. Replacement reserve funds must be deposited with HUD or in a Federally-insured depository in an interest-bearing account(s) whose balances are fully insured at all times. All earnings including interest on the reserve must be added to the reserve.
