style="font-family:inherit;font-size:9pt;">We periodically revise the key assumptions used in the calculation of amortization of deferred policy acquisition costs and deferred sales inducements retrospectively through an unlocking process when estimates of current or future gross profits/margins (including the impact of realized investment gains and losses) to be realized from a group of products are revised. In addition, we periodically revise the assumptions used in determining reserves held for lifetime income benefit riders as experience develops that is different from our assumptions. </font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">The unlocking adjustments in </font><font style="font-family:inherit;font-size:9pt;">2017</font><font style="font-family:inherit;font-size:9pt;"> decreased amortization of deferred policy acquisition costs by </font><font style="font-family:inherit;font-size:9pt;">$48.2 million</font><font style="font-family:inherit;font-size:9pt;"> and amortization of deferred sales inducements by </font><font style="font-family:inherit;font-size:9pt;">$34.3 million</font><font style="font-family:inherit;font-size:9pt;">. During the third quarter of 2017, the most significant revisions to such assumptions were account balance true-ups which were favorable to us due to stronger index credits than we assumed due to strong equity market performance and adjustments to generally decrease lapse rate assumptions to reflect better persistency experienced than assumed. The favorable impact of the account balance true-ups and lapse rate assumption changes was partially offset by reductions in estimated future gross profits attributable to revisions to assumptions used in determining reserves held for lifetime income benefit riders as well as an increase in estimated expenses associated with a reinsurance agreement with an unaffiliated reinsurer.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">The unlocking adjustments in </font><font style="font-family:inherit;font-size:9pt;">2016</font><font style="font-family:inherit;font-size:9pt;"> increased amortization of deferred policy acquisition costs by </font><font style="font-family:inherit;font-size:9pt;">$48.2 million</font><font style="font-family:inherit;font-size:9pt;"> and amortization of deferred sales inducements by </font><font style="font-family:inherit;font-size:9pt;">$35.8 million</font><font style="font-family:inherit;font-size:9pt;">. During the first quarter of 2016, we made adjustments to lower future spread assumptions as actual investment spreads being earned showed investment spread and gross profits being less than what we were assuming in our models due to decreases in the average yield on invested assets resulting from the continued low interest rate environment. We made further adjustments in the third quarter of 2016 to extend the period of time in which we assume investment spread will grade up to our long-term spread targets by an additional two years as yields obtained on investments purchased in the third quarter of 2016 were much lower than we had anticipated as a result of the overall decline in investment yields that followed the Brexit vote. In addition, during the third quarter of 2016, revisions to assumptions used in determining reserves held for living income benefit riders resulted in a decrease in estimated future gross profits.</font></div><div style="line-height:120%;padding-bottom:12px;padding-top:12px;text-align:justify;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">The unlocking adjustments in </font><font style="font-family:inherit;font-size:9pt;">2015</font><font style="font-family:inherit;font-size:9pt;"> decreased amortization of deferred policy acquisition costs by </font><font style="font-family:inherit;font-size:9pt;">$11.0 million</font><font style="font-family:inherit;font-size:9pt;"> and amortization of deferred sales inducements by </font><font style="font-family:inherit;font-size:9pt;">$5.6 million</font><font style="font-family:inherit;font-size:9pt;"> and included the impact of account balance true-ups as of September 30, 2015, which were favorable to us due to stronger equity market performance than we assumed, favorable adjustments to lapse assumptions to reflect better persistency experienced than assumed and unfavorable adjustments to investment spread to reflect lower spreads being earned than assumed.

The 2017 revisions increased interest sensitive and index product benefits by </font><font style="font-family:inherit;font-size:9pt;">$21.6 million</font><font style="font-family:inherit;font-size:9pt;"> and were primarily due to the lapse rate assumption changes described above and changes to our account value growth projections. The 2016 revisions increased interest sensitive and index product benefits by </font><font style="font-family:inherit;font-size:9pt;">$42.0 million</font><font style="font-family:inherit;font-size:9pt;"> and were primarily due to actual index credits on policies being lower than projected over the past four quarters. The 2015 revisions increased interest sensitive and index product benefits by </font><font style="font-family:inherit;font-size:9pt;">$18.3 million</font><font style="font-family:inherit;font-size:9pt;"> and were primarily due to an increase to the primary election age to begin receiving lifetime income from </font><font style="font-family:inherit;font-size:9pt;">67</font><font style="font-family:inherit;font-size:9pt;"> to </font><font style="font-family:inherit;font-size:9pt;">70</font><font style="font-family:inherit;font-size:9pt;"> as our experience had shown that age </font><font style="font-family:inherit;font-size:9pt;">70</font><font style="font-family:inherit;font-size:9pt;"> is the most popular age at which policyholders elect to begin receiving lifetime income benefit payments. The lifetime income benefit payments are determined by applying a payout factor to the rider's benefit base. The reserve (net of coinsurance ceded) held for lifetime income benefit riders was </font><font style="font-family:inherit;font-size:9pt;">$704.4 million</font><font style="font-family:inherit;font-size:9pt;"> and </font><font style="font-family:inherit;font-size:9pt;">$533.4 million</font><font style="font-family:inherit;font-size:9pt;"> at </font><font style="font-family:inherit;font-size:9pt;">December 31, 2017</font><font style="font-family:inherit;font-size:9pt;"> and </font><font style="font-family:inherit;font-size:9pt;">2016</font><font style="font-family:inherit;font-size:9pt;">, respectively.</font></div></div> | |

Significant estimates and assumptions are utilized in the calculation of deferred policy acquisition costs, deferred sales inducements, policy benefit reserves, valuation of derivatives, including embedded derivatives on index annuity reserves, contingent convertible senior notes, valuation of investments, other than temporary impairment of investments, allowances for loan losses on mortgage loans and valuation allowances on deferred tax assets. A description of each critical estimate is incorporated within the discussion of the related accounting policies which follow. It is reasonably possible that actual experience could differ from the estimates and assumptions utilized.</font></div></div> |
