Fair Value Disclosures [Abstract] |
Fair Value of Financial Instruments, Policy [Policy Text Block] | The Company's estimates of fair value for financial assets and financial liabilities are based on the framework established in the fair value accounting guidance. The framework is based on the inputs used in valuation, gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available. The Company categorizes its assets and liabilities measured at estimated fair value based on whether the significant inputs into the valuation are observable. The fair value hierarchy categorizes the inputs in the valuation techniques used to measure fair value into three broad Levels (Level 1, 2 or 3).
Level 1 | Unadjusted quoted prices for identical assets, or liabilities, in active markets that the Company has the ability to access at the measurement date.
Level 2 | Observable inputs, other than quoted prices included in Level 1, for the asset or liability, or prices for similar assets and liabilities.
Level 3 | Valuations that are derived from techniques in which one or more of the significant inputs are unobservable (including assumptions about risk). 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. 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 within illiquid markets and/or priced by independent brokers. The following tables present assets and (liabilities) carried at fair value by hierarchy level. Upon implementation of the new disclosure guidance effective in 2016 certain NAV-based fair values are no longer included in the fair value level disclosures; however, these amounts are included in the total fair value disclosed. As a result, prior period values for limited partnerships and other alternative investments and separate account assets have been removed from Level 2 and Level 3. Valuation Techniques, Procedures and Controls 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 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.
