Fair Value Disclosures [Abstract] |
Fair Value of Financial Instruments, Policy [Policy Text Block] | The following section applies to the fair value hierarchy and disclosure requirements for the Company’s financial instruments that are carried at fair value. The fair value hierarchy prioritizes the inputs in the valuation techniques used to measure fair value into three broad Levels (Level 1, 2 or 3).
Level 1 | Observable inputs that reflect quoted prices for identical assets, or liabilities, in active markets that the Company has the ability to access at the measurement date. Level 1 securities include highly liquid U.S. Treasuries, money market funds and exchange traded equity securities, open-ended mutual funds, and exchange-traded derivative instruments.
Level 2 | Observable inputs, other than quoted prices included in Level 1, for the asset or liability, or prices for similar assets and liabilities. Most fixed maturities and preferred stocks, including those reported in separate account assets, are model priced by vendors using observable inputs and are classified within Level 2. Also included are hedge funds where investment company accounting guidance has been applied to a wholly-owned fund of funds measured at fair value w here an investment can be redeemed, or substantially redeemed, at the net asset value per share or equivalent ("NAV") on the measurement date or in the near-term, not to exceed 90 days. Derivative instruments classified within Level 2 are priced using observable market inputs such as swap yield curves and credit default swap curves.
Level 3 | Valuations that are derived from techniques in which one or more of the significant inputs are unobservable (including assumptions about risk). Level 3 securities include less liquid securities, guaranteed product embedded and reinsurance derivatives and other complex derivative instruments, as well as hedge fund investments carried at fair value, consistent with investment company accounting guidance, that cannot be redeemed in the near-term at the NAV. Because Level 3 fair values, by their nature, contain one or more significant unobservable inputs, as there is little or no observable market for these assets and liabilities, considerable judgment is used to determine the Level 3 fair values. Level 3 fair values represent the Company’s best estimate of an amount that could be realized in a current market exchange absent actual market exchanges.
In many situations, inputs used to measure the fair value of an asset or liability position may fall into different levels of the fair value hierarchy. In these situations, the Company will determine the level in which the fair value falls based upon the lowest level input that is significant to the determination of the fair value. Transfers of securities among the levels occur at the beginning of the reporting period. The amount of transfers from Level 1 to Level 2 was $417 and $524, for the three and six months ended June 30, 2015, respectively, and $309 and $1.6 billion for the three and six months ended June 30, 2014, respectively, which represented previously on-the-run U.S. Treasury securities that are now off-the-run. For the three and six months ended June 30, 2015 and 2014, there were no transfers from Level 2 to Level 1. In most cases, both observable (e.g., changes in interest rates) and unobservable (e.g., changes in risk assumptions) inputs are used in the determination of fair values that the Company has classified within Level 3. Consequently, these values and the related gains and losses are based upon both observable and unobservable inputs. The Company’s fixed maturities included in Level 3 are classified as such because these securities are primarily priced by independent brokers and/or within illiquid markets. The following tables present assets and (liabilities) carried at fair value by hierarchy level. These disclosures provide information as to the extent to which the Company uses fair value to measure financial instruments and information about the inputs used to value those financial instruments to allow users to assess the relative reliability of the measurements Determination of Fair Values The valuation methodologies used to determine the fair values of assets and liabilities under the “exit price” notion, reflect market participant objectives and are based on the application of the fair value hierarchy that prioritizes relevant observable market inputs over unobservable inputs. The Company determines the fair values of certain financial assets and liabilities based on quoted market prices where available, and where prices represent a reasonable estimate of fair value. The Company also determines fair value based on future cash flows discounted at the appropriate current market rate. Fair values reflect adjustments for counterparty credit quality, the Company’s default spreads, liquidity, and where appropriate, risk margins on unobservable parameters. The following is a discussion of the methodologies used to determine fair values for the financial instruments listed in the preceding tables. The fair value process is monitored by the Valuation Committee, which is a cross-functional group of senior management within the Company that meets at least quarterly. The Valuation Committee is co-chaired by the Heads of Investment Operations and Accounting, and has representation from various investment sector professionals, accounting, operations, legal, compliance, and risk management. The purpose of the committee is to oversee the pricing policy and procedures by ensuring objective and reliable valuation practices and pricing of financial instruments, as well as addressing valuation issues and approving changes to valuation methodologies and pricing sources. There are also two working groups under the Valuation Committee, a Securities Fair Value Working Group (“Securities Working Group”) and a Derivatives Fair Value Working Group ("Derivatives Working Group"), which include various investment, operations, accounting and risk management professionals that meet monthly to review market data trends, pricing and trading statistics and results, and any proposed pricing methodology changes. The Company also has an enterprise-wide Operational Risk Management function, led by the Chief Operational Risk Officer, which is responsible for establishing, maintaining and communicating the framework, principles and guidelines of the Company's operational risk management program. This includes model risk management which provides an independent review of the suitability, characteristics and reliability of model inputs, as well as an analysis of significant changes to current models.
