text: Insurance Segment
text: (1) The Insurance segment revenues are inclusive of realized and unrealized gains and net investment income for the year ended December 31, 2019 and 2018. Such adjustments are related to transactions between entities under common control which are eliminated or are reclassified in consolidation.
text: Life, accident and health earned premiums, net: Life, accident and health earned premiums, net from our Insurance segment for the year ended December 31, 2019 increased $22.4 million to $116.8 million from $94.4 million for the year ended December 31, 2018. The increase was primarily due to the premiums generated from the acquisition of KIC in 2018.
text: Net investment income: Net investment income from our Insurance segment for the year ended December 31, 2019 increased $95.8 million to $212.9 million from $117.1 million for the year ended December 31, 2018. The increase was primarily due to the income generated from the assets acquired in the KIC acquisition, higher average invested assets as a result of the reinvestment of premiums and investment income received, and to a lesser extent, rotation into higher-yielding investments.
text: Net realized and unrealized gains on investments: Net realized and unrealized gains on investments from our Insurance segment for the year ended December 31, 2019 decreased $3.7 million to $1.9 million from $5.6 million for the year ended December 31, 2018. The decrease was driven by smaller realized gains on bonds and common stocks, higher impairments, and losses on fair value changes on interest only bonds in 2019. The decrease was offset by overall improvement in fair value changes in equity securities and realized gains on mortgage loans in 2019.
text: Policy benefits, changes in reserves, and commissions: Policy benefits, changes in reserves, and commissions from our Insurance segment for the year ended December 31, 2019 increased $37.1 million to $234.4 million from $197.3 million for the year ended December 31, 2018. The increase was primarily driven by KIC, which generated policy benefits, changes in reserves, and commissions in the current year but was present for a shorter duration in 2018 due to the timing of the acquisition in August 2018. This was partially offset by current period reserve releases driven by higher mortality and policy terminations, an increase in contingent non-forfeiture option activity as a result of in-force rate actions approved and implemented, and favorable developments in claim incidences and termination rates and estimates of benefits on open claims.
text: Selling, general and administrative: Selling, general and administrative expenses from our Insurance segment for the year ended December 31, 2019 increased $5.3 million to $35.7 million from $30.4 million for the year ended December 31, 2018. The increase was driven by higher headcount, accounting, and consulting fees associated with the acquisition of KIC offset by a reduction in legal fees.
text: Depreciation and amortization: Depreciation and amortization from our Insurance segment for the year ended December 31, 2019 increased $10.7 million to $23.1 million from $12.4 million for the year ended December 31, 2018. The increase was driven by the increase in negative VOBA amortization largely due to the KIC acquisition. Amortization of negative VOBA reflects an increase to net income.
text: Other operating expense: $47.3 million of other operating expense for the year ended December 31, 2019 was driven by impairment of goodwill in the fourth quarter of 2019. The Insurance segment's operating entity, CGI, had a book value at December 31, 2019 of $503.6 million, inclusive of $198.9 million of AOCI. The increase in 2019 was largely driven by current year net income of $98.7 million, before the impact of the goodwill impairment, and an increase in AOCI of $288.0 million from December 31, 2018.
text: There were several factors that occurred in the fourth quarter of 2019, which impacted the fair value of the Insurance segment, primarily with respect to the future of the management fee agreement, along with our expectations of future dividends, after recent and ongoing discussions with our domestic regulator. While these factors do not have a major impact on the operations of the business, they do impact the ability to capture the value which is effectively trapped in the Insurance company.
text: As a result of the factors described above, our book value at CGI exceeded fair value, and the Company recognized a goodwill impairment charge of $47.3 million at our Insurance segment. Net income of CGI, after the impact of the goodwill impairment was $51.4 million for the year ended December 31, 2019. At December 31, 2019, after the impact of the goodwill impairment, the book value of CGI was $456.3 million, and we would expect additional book losses to the extent CGI is sold in the future.
