Any unexpended balance in the fund at the end of the fiscal year shall not revert to the General Fund but shall remain available for expenditure in subsequent fiscal years. No expenditure made from the fund shall cause the fund to become deficient at any point during a fiscal year.\nThe dairy promotion board, established in subsection (a) of section 30, shall have exclusive authority to receive, deposit, invest and expend monies pursuant to section 30. The books and records of the Dairy Promotion Trust Fund shall be subject to an audit by the state auditor, in accordance with generally accepted government auditing standards, as often as the state auditor determines is necessary.
