Entries are made to "Other Comprehensive Income", and then OCI is closed out to "Accumulated Other Comprehensive Income". This process is the same as Net Income being closed out to Retained Earnings. The entries to OCI follow the same logic as entries to the Income Statement except they are booked net of tax. Gains are credits and Losses are debits. The balance of the AOCI account depends on the prior entries that have been booked. It is important to read the questions and access if they are asking about OCI (I/S) or AOCI (B/S). The entries to OCI pertain to the transaction while the entries to AOCI pertain to the effect the entries have on the running balance in AOCI.

The entry to record deferred pension gains:

DR: Pension benefit obligation - (Lowers the B/S liability)

CR: Other comprehensive income - (Records the gain in OCI)

DR: Deferred tax expense - OCI - (Records the tax expense in OCI)

CR: Deferred tax liability - BS - (Increase deferred tax liability because it is a gain)

The entry to record subsequent amortization of the gain:

DR: Other comprehensive income - (Reverses the portion of the gain in OCI)

CR: Net periodic pension cost - IS - (Reduces the current pension expense)

DR: Deferred tax expense - IS - (Records the deferred tax on the IS)

CR: Deferred tax expense - OCI - (Reverses the deferred tax in OCI)
