Ohio Rev. Code Ann. § 3307.141

Wherever in this chapter, reference is made to the teachers' savings fund, the employers' trust fund, the annuity and pension reserve fund, the guarantee fund, the survivors' benefit fund, the expense fund, or the defined contribution fund, such reference shall be construed to have been made to each as a separate legal entity. This section does not prevent the deposit or investment of all such moneys intermingled for such purpose but such funds shall be separate and distinct legal entities for all other purposes.
