Under current GASB standards, how are other postemployment retirement benefits (OPEB) reported? By disclosing information about OPEB in the notes to the financial statements, but without display of OPEB expenses or liabilities on the face of the financial statements. In a manner that is quite similar to the reporting requirements for pension plans. Using two different methods, one for health care plans and a second for other types of OPEB. By using a modified accrual basis, which requires only expenditures of the current period be reported.
