Fair Value Option [Abstract]  
Fair Value Option
Fair Value Option
Gains and losses due to changes in fair value for items measured at fair value pursuant to application of the fair value option are included in net realized investment (losses) gains in the Company’s consolidated statements of operations, while interest and dividend income on investment holdings are recognized on an accrual basis on each measurement date and are included in net investment income in the Company’s consolidated statements of operations. The primary reasons for electing the fair value option were simplification and cost-benefit considerations as well as expansion of use of fair value measurement consistent with the long-term measurement objectives of the FASB for accounting for financial instruments.
The following table presents gains and losses due to changes in fair value of investments that are measured at fair value pursuant to application of the fair value option:
