The Treasury Department is responsible for managing the District's cash, investment and debt portfolios. The department monitors and adjusts the District's cash and investment position to meet daily liquidity needs while maximizing investment returns. An Investment Policy developed by the department and adopted by the Board guides the types and duration of investment tools utilized to manage the cash position of the District. Responsibilities for managing the debt portfolio include maintaining record of and ensuring proper payment of all outstanding debt. Treasury also evaluates bond transaction proposals and refunding structures in order to determine the most cost effective method of financing a portion of the District's capital needs as well as managing its long- term debt obligations.
