Ohio Rev. Code § 761.12
Moneys in the funds established under sections 761.10 and 761.11 of the Revised Code, except as otherwise provided in any ordinance authorizing such revenue bonds or in any trust agreement securing such bonds, in excess of current needs, may be invested in notes, bonds, or other obligations of the United States. If the law or the instrument creating a trust pursuant to section 761.09 of the Revised Code expressly permits investment in direct obligations of the United States or an agency thereof, unless expressly prohibited by the instrument, such moneys also may be invested in no front end load money market mutual funds consisting exclusively of obligations of the United States or an agency thereof and in repurchase agreements, including those issued by the fiduciary itself, secured by obligations of the United States or an agency thereof; and in collective investment funds established in accordance with section 1111.14 of the Revised Code and consisting exclusively of any such securities, notwithstanding division (A)(1)(c) of that section.
Income from all such investments of money in any fund shall be credited to such funds as the municipal corporation determines subject to the provisions of any such ordinance or trust agreement, and such investments may be sold at such time as the municipal corporation shall determine.
