At the close of each fiscal year, the county treasurer shall make a report to the county, giving a particular account of all the treasurer's financial transactions during the year. The treasurer shall furnish to the commissioners statements from the books, and submit the books and vouchers to them and to the county auditors for examination, whenever so requested. IV. Whenever the county treasurer has in custody an excess of funds which are not immediately needed for the purpose of expenditure, the treasurer shall, with the approval of the commissioners, invest the same in obligations of the United States government, in participation units in the public deposit investment pool established pursuant to RSA 6:45, or in deposits, including money market accounts, or certificates of deposit, or repurchase agreements, and all other types of interest bearing accounts, of federally insured banks authorized to accept deposits under RSA 6:8, I and I-a.

Such collateral shall be segregated for the exclusive benefit of the county.

(d) The selected bank acts as custodian with respect to each such deposit for the account of the treasurer. (e) On the same date that the funds are redeposited by the selected bank, the selected bank receives an amount of deposits from customers of other federally insured financial institutions equal to or greater than the amount of the funds initially invested through the selected bank by the treasurer.
