K.S.A. 75-4210a

Interest earned on state moneys shall be credited to the state general fund, unless required by law, contract or bequest to be credited to a fund other than the state general fund. When interest earnings are required by law, contract or bequest to be credited to a fund other than the state general fund, such earnings shall be based on the average daily balance in the fund for each month and the net earnings rate of the pooled money investment portfolio for such month unless such law, contract or bequest provides a different method of computing interest earnings.
