Ohio Rev. Code § 145.25: Each fund is separate legal entity.

When reference is made in this chapter, to the employees' savings fund, the employers' accumulation fund, the annuity and pension reserve fund, the income fund, the survivors' benefit fund, the defined contribution fund, or the expense fund, such reference is 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.
