Results of Operations

Underwriting Results

Gross written premiums were $84.6 million for the three months ended March 31, 2019 compared to $63.8 million for the three months ended March 31, 2018, an increase of 32.5%. The increase in gross written premiums in the first quarter 2019 over the same period last year was due to strong growth in broker submissions across substantially all lines of business.

Underwriting income⁽²⁾ was $12.1 million, resulting in a combined ratio of 80.3%, for the first quarter of 2019, compared to $6.8 million, and a combined ratio of 85.9% for the same period last year. The increase in underwriting income⁽²⁾ was due primarily to higher favorable development on loss reserves from prior accident years and growth in the business quarter over quarter. Loss and expense ratios were 54.9% and 25.4%, respectively, for the three months ended March 31, 2019 compared to 60.1% and 25.8% for the three months ended March 31, 2018. Results for the first quarters of 2019 and 2018 included favorable development on loss reserves from prior accident years of $6.4 million, or 10.4 points, and $1.3 million, or 2.7 points, respectively.

Investment Results

The Company’s net investment income was $4.5 million in the first quarter of 2019 compared to $3.2 million in the first quarter of 2018, an increase of 39.8%. The Company’s investment portfolio, excluding cash and cash equivalents, had an annualized gross investment return⁽⁵⁾ of 3.2% for the three months ended March 31, 2019 compared to 2.7% for the three months ended March 31, 2018. Funds are generally invested conservatively in high quality securities, including government agency, asset and mortgage-backed securities, 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 3.9 years at March 31, 2019 and December 31, 2018. Cash and invested assets totaled $708.1 million at March 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 the change in after-tax unrealized gains and losses from the Company’s available-for-sale investments, was $25.5 million for the first quarter of 2019 compared to $2.4 million for the first quarter of 2018. The increase in total comprehensive income was principally due to an increase in the fair value of Company's fixed-maturity investments, which was mostly attributable to a declining interest rate environment during the quarter.

Stockholders' equity was $288.9 million at March 31, 2019, compared to $264.0 million at December 31, 2018. Annualized operating return on equity was 20.0% for the first quarter of 2019, an increase from 13.7% for the first quarter of 2018, which was attributable to favorable development on loss reserves from prior accident years and growth in the business quarter over quarter.

The effective tax rates for the three months ended March 31, 2019 and 2018 were 17.9% and 17.3%. The effective tax rates were lower than the federal statutory rate of 21% due to the tax benefits from the exercise of stock options and from income generated by certain tax-advantaged investments.

Non-GAAP Financial Measures

Net Operating Earnings

Net operating earnings exclude the effect of realized investment gains and losses and unrealized gains and losses on equity securities. 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 ended March 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 March 31,
	2019			2018
	($ in thousands, except per share data)
Net operating earnings:
Net income	$	18,720		$	7,287

Net realized gains on investments, after taxes	(221		)	(88		)

⁽²⁾	Annualized return on equity is net income expressed on an annualized basis as a percentage of average stockholders’ equity during the period.


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

Underwriting Income

Underwriting income is defined as pre-tax income excluding net investment income, realized gains and losses on investments, unrealized gains and losses on equity securities, and other income and expenses. 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 ended March 31, 2019 and 2018, net income reconciles to underwriting income as follows:



	Three Months Ended March 31,
	2019			2018
	(in thousands)
Net income	$	18,720		$	7,287
