Fair value measurements for items measured at fair value

Assets measured at fair value, by hierarchy level, as of June 30, 2018 and December 31, 2017 are shown in tables 8.1a and 8.1b below. The fair value of the assets is estimated using the process described above, and more fully in Note 3 - “Significant Accounting Policies” of the notes to the consolidated financial statements in our 2017 Annual Report on Form 10-K.

Reconciliation of beginning and ending balance for assets and liabilities measured at fair value with significant unobservable inputs (level 3)

For assets measured at fair value using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances for the three and six months ended June 30, 2018 and 2017 is shown in tables 8.2a and 8.2b and 8.3a and 8.3b below. As described in Note 2 - “New Accounting Pronouncements,” under updated guidance regarding the Recognition and Measurement of Financial Assets and Financial Liabilities which became effective on January 1, 2018, our investment in FHLB stock is no longer presented with equity securities. Prior to the updated guidance, our FHLB stock was included in our Level 3 equity securities. As shown in table 8.3a below, for the six months ended June 30, 2018, we have transferred our FHLB stock out of Level 3 assets, and it is carried at cost, which approximates fair value, on our consolidated balance sheet in “Other invested assets” as of June 30, 2018. There were no losses included in earnings for those periods attributable to the change in unrealized losses on assets still held at the end of the applicable period.

Carrying value and fair value of debt

Table 8.4 presents the carrying value and fair value of our financial liabilities disclosed, but not carried, at fair value at June 30, 2018 and December 31, 2017. The fair values of our 5.75% Notes and 9% Debentures were based on observable market prices. The fair value of the FHLB Advance was estimated using discounted cash flows on current incremental borrowing rates for similar borrowing arrangements. In all cases the fair values of the financial liabilities below are categorized as Level 2.
