Under the historical rate approach, the amount of AOCI reclassified to net income each period would be translated from the functional currency of the foreign operation to the reporting currency at the historical exchange rate in effect at the time the prior service costs/credits, net gain or loss, and transition asset/obligation were initially recognized in OCI.
This approach is consistent with the principles in
ASC 220, which defines OCI as revenues, expenses, gains, and losses that under GAAP are included in comprehensive income but excluded from net income. In the context of
ASC 220, the initial recognition of pension-related amounts in OCI (i.e., the change in equity - or net assets - not arising from owner transactions), and not the reclassification adjustment, is the income recognition event that triggers translation into the reporting currency.
Based on this view, a reclassification from one component of income (OCI) to another (net income, and, in turn, retained earnings) is merely a recycling of amounts previously recognized and translated at the exchange rate in effect at the time those amounts were previously recognized. Therefore, the exchange rate used to translate an item recognized in OCI should not change when that item is later reclassified to net income.
This approach is also consistent with the treatment of retained earnings under
ASC 830. The amount of net income that an entity reports each period is translated at the exchange rates in effect during that period. Once translated, that net income accumulates in retained earnings and is not subsequently retranslated at a current rate (i.e., retained earnings balances do not fluctuate from period to period based on changes in exchange rates). Similarly, amounts accumulated in AOCI are not retranslated. Therefore, AOCI amounts that are reclassified to net income should not be retranslated in the period they are recorded in net income.
Implementation and tracking—historical rate approach
Amounts in AOCI may be amortized and recognized in net periodic benefit expense over many future years. As a result, entities that adopt the historical rate approach will need to develop processes to track the foreign currency rates in effect in each period when prior service costs/credits and gains or losses are added to AOCI. Entities will also need to develop policies to determine the "layer" of AOCI that is reclassified into the income statement.
We believe that there are many reasonable approaches that entities might adopt to track the historical rates to be used when reclassifying amounts from AOCI to net income. For example, an entity might adopt a policy of reclassifying AOCI amortization on a FIFO basis, such that the first dollar of AOCI loss reclassified would be translated at the exchange rate in effect when the first dollar of loss was recognized in AOCI. Alternatively, an entity might adopt a policy of developing a blended historical average rate for all amounts in AOCI, and this rate would be updated each time new amounts are added to AOCI. Entities should elect an approach and consistently follow it.
