Consolidation

All intercompany transactions and balances between HMEC and its subsidiaries and affiliates have been eliminated.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the reporting date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

The most significant critical accounting estimates include valuation of hard-to-value fixed maturity securities (including evaluation of impairments), evaluation of goodwill and intangible assets for impairment, valuation of annuity and life deferred policy acquisition costs, valuation of liabilities for property and casualty unpaid claims and claim expenses and valuation of certain investment contracts and policy reserves.

Future Adoption of New Accounting Standards

Accounting for Long-Duration Insurance Contracts

In August 2018, the FASB issued accounting and disclosure guidance that contains targeted improvements to the accounting for long-duration insurance contracts. Under the new guidance, the cash flow assumptions used to measure the liability for future policy benefits for traditional insurance contracts will be required to be updated at least annually with changes recognized as a benefit expense (i.e., assumptions will no longer be locked-in).

Insurance entities will be required to use a standard discount rate to measure the liabilities that will be equivalent to the yield from a high-quality bond. The new guidance also changes the amortization of deferred policy acquisition costs (DAC) to be on a constant-level basis over the expected term of the related contracts with no interest accruing on the DAC balance. The new guidance also introduces a new category of contract features associated with deposit type contracts referred to as market risk benefits (MRBs). Contract features meeting the definition of a MRB will be measured at fair value.
