Although the call options are employed to be effective hedges against our policyholder obligations from an economic standpoint, they do not meet the requirements for hedge accounting under GAAP. Accordingly, the changes in fair value of the call options are recognized each reporting date as a component of net investment and interest income. The change in fair value of the call options include the gains or losses recognized at the expiration of the option term and the changes in fair value for open contracts.
