CY2014	us-gaap	Description Of New Accounting Pronouncements Not Yet Adopted DescriptionOfNewAccountingPronouncementsNotYetAdopted	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;padding-bottom:13px;padding-top:6px;text-align:left;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2014, the Financial Accounting Standards Board (“FASB”) issued amended guidance on revenue recognition. The amended guidance affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. Insurance contracts are within the scope of other standards and therefore are specifically excluded from the scope of the amended revenue recognition guidance. The core principle of the amended guidance is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve the core principle, the entity applies a five step process outlined in the amended guidance. The amended guidance also includes a cohesive set of disclosure requirements. The amended guidance is effective for interim and annual periods beginning after December 15, 2016 and early adoption is not permitted. Therefore, the Company is required to adopt the guidance on January 1, 2017. An entity can choose to apply the amended guidance using either the full retrospective approach or a modified retrospective approach. The Company is currently evaluating the requirements of the revenue recognition guidance as it relates to its non-insurance contract revenue and the potential impact on the Company’s financial position and results of operations.</font></div></div>

The items on the Company’s balance sheets affected by the use of estimates include but are not limited to, investments, premiums and accounts receivable, reinsurance recoverables, deferred acquisition costs (“DAC”), deferred income taxes and associated valuation allowances, goodwill, valuation of business acquired (“VOBA”), future policy benefits and expenses, unearned premiums, claims and benefits payable, deferred gain on disposal of businesses, pension and post-retirement liabilities and commitments and contingencies. The estimates are sensitive to market conditions, investment yields, mortality, morbidity, commissions and other acquisition expenses, policyholder behavior and other factors. Actual results could differ from the estimates recorded. The Company believes all amounts reported are reasonable and adequate.</font></div></div>
