Investment Results

The Company’s net investment income was $5.5 million in the fourth quarter of 2019 compared to $4.6 million in the fourth quarter of 2018, an increase of 20.8%. Net investment income was $20.1 million for the full year of 2019 compared to $15.7 million for the full year of 2018. The Company’s investment portfolio, excluding cash and cash equivalents, had a gross investment return⁽⁵⁾ of 3.1% for the year ended December 31, 2019 compared to 3.0% for the year ended December 31, 2018. Funds are generally invested conservatively in high quality securities, including government agency, mortgage-backed, municipal and corporate bonds with an average credit quality of "AA." The weighted average duration of the fixed-maturity investment portfolio, including cash equivalents, was 4.3 years at December 31, 2019 and 3.9 years at December 31, 2018. Cash and invested assets totaled $908.2 million at December 31, 2019 compared to $643.1 million at December 31, 2018.


⁽⁵⁾	Gross investment return is investment income from fixed-maturity and equity securities, before any deductions for fees and expenses, expressed as a percentage of average beginning and ending balances of those investments during the period.

Other

Total comprehensive income, which includes net income and the change in after-tax unrealized gains and losses from the Company’s available-for-sale investments, was $78.1 million for the full year of 2019 compared to $28.3 million for the full year of 2018. The improvement in unrealized gains during 2019 related to higher fair values of the Company's fixed-maturity investments, which was mostly attributable to a lower interest rate environment.

The effective tax rate for the year ended December 31, 2019 was 16.7%. The effective tax rate was lower than the federal statutory rate principally due to the tax benefits from the exercise of stock options and from interest income generated by certain tax-advantaged investments.

Stockholders' equity was $405.9 million at December 31, 2019, compared to $264.0 million at December 31, 2018. Operating return on equity was 15.9% for the full year of 2019, an increase from 15.4% for the full year of 2018, which was attributable to growth in the business year over year, offset in part by the proceeds received from the Company's equity offering in the third quarter of 2019 of $65.9 million.

Non-GAAP Financial Measures

Net Operating Earnings

Net operating earnings is defined as net income excluding the effects of net unrealized gains and losses on equity securities, after taxes, and net realized gains and losses on investments, after taxes. Management believes the exclusion of these items provides a more useful comparison of the Company's underlying business performance from period to period. Net operating earnings and percentages or calculations using net operating earnings (e.g., diluted operating earnings per share and annualized operating return on equity) are non-GAAP financial measures. Net operating earnings should not be viewed as a substitute for net income calculated in accordance with GAAP, and other companies may define net operating earnings differently.

For the three months and year ended December 31, 2019 and 2018, net income and diluted earnings per share reconcile to net operating earnings and diluted operating earnings per share as follows:



	Three Months Ended December 31,						Year Ended December 31,

	($ in thousands, except per share data)

⁽¹⁾	Diluted operating earnings per share may not add due to rounding.


⁽²⁾	Computed by adding the total stockholders' equity as of the date indicated to the prior quarter-end or year-end total, as applicable, and dividing by two.


⁽³⁾	Annualized return on equity is net income expressed on an annualized basis as a percentage of average total stockholders’ equity during the period.


⁽⁴⁾	Annualized operating return on equity is net operating earnings expressed on an annualized basis as a percentage of average total stockholders’ equity during the period.

Underwriting Income

Underwriting income is defined as net income excluding net investment income, net unrealized gains and losses on equity securities, net realized gains and losses on investments, other income, other expenses and income tax expense. The Company uses underwriting income as an internal performance measure in the management of its operations because the Company believes it gives management and users of the Company's financial information useful insight into the Company's results of operations and underlying business performance. Underwriting income should not be viewed as a substitute for net income calculated in accordance with GAAP, and other companies may define underwriting income differently.

For the three months and year ended December 31, 2019 and 2018, net income reconciles to underwriting income as follows:



	Three Months Ended December 31,						Year Ended December 31,
	2019			2018			2019			2018
	(in thousands)
Net income	$	17,853		$	4,448		$	63,316		$	33,787
