Notes to Condensed Consolidated Financial Statements (Unaudited)

1.    Summary of significant accounting policies

Basis of presentation

The accompanying condensed consolidated financial statements and notes have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and do not contain all of the information and footnotes required by U.S. GAAP for complete financial statements. For a more complete description of the Company’s business and accounting policies, these condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements of Kinsale Capital Group, Inc. and its wholly owned subsidiaries (the "Company") included in the Annual Report on Form 10-K for the year ended December 31, 2017. In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. All significant intercompany balances and transactions have been eliminated in consolidation. Interim results are not necessarily indicative of results of operations for the full year.

Use of estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management periodically reviews its estimates and assumptions.

Recently adopted accounting pronouncements

ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities

In January 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-01, "Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities" ("ASU 2016-01"), which eliminated the available-for-sale classification for equity investments, required changes in unrealized gains and losses in fair value of equity investments to be recognized in net income, required public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, required separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminated the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that was required to be disclosed for financial instruments measured at amortized cost. Effective January 1, 2018, the Company adopted this ASU and recorded a cumulative-effect adjustment, which reclassified unrealized gains of $6.5 million, net of $1.7 million of taxes, on equity investments from accumulated other comprehensive income ("AOCI") to retained earnings. Prior periods have not been restated to conform to the current presentation. 

ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income

In February 2018, the FASB issued ASU 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which permitted companies to reclassify the disproportionate income tax effects of the Tax Cuts and Jobs Act of 2017 (the "TCJA") on items within AOCI to retained earnings. The FASB refers to these amounts as "stranded tax effects." The guidance is effective for all companies for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Effective January 1,

6

2018, the Company elected to early adopt this ASU and to reclassify the stranded income tax effects for available-for-sale securities of $1.3 million from AOCI to retained earnings. Other than those effects related to the TCJA, the Company uses the portfolio approach to release stranded tax effects in AOCI related to its available-for-sale fixed-maturity securities and its available-for-sale equity securities (prior to the adoption of ASU 2016-01). Under this approach, stranded tax effects remaining in AOCI are released only when the entire portfolio of the available-for-sale fixed-maturity securities and available-for-sale equity securities are liquidated, sold or extinguished.

Prospective accounting pronouncements

ASU 2016-02, Leases (Topic 842)

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" to improve the financial reporting of leasing transactions. Under this ASU, lessees will recognize a right-of-use asset and corresponding liability on the balance sheet for all leases, except for leases covering a period of 12 months or less. The liability is to be initially measured at the present value of the future minimum lease payments taking into account renewal options if applicable plus initial incremental direct costs such as commissions. The minimum payments are discounted using the rate implicit in the lease or, if not known, the lessee’s incremental borrowing rate at the inception of the lease. The lessee’s income statement treatment for leases will vary depending on the nature of what is being leased. A financing type lease is present when, among other matters, the asset is being leased for a substantial portion of its economic life or has an end-of-term title transfer or a bargain purchase option as in today’s practice. The payment of the liability set up for such leases will be apportioned between interest and principal; the right-of use asset will be generally amortized on a straight-line basis. If the lease does not qualify as a financing type lease, it will be accounted for on the income statement as rent on a straight-line basis. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018. Early adoption is permitted. The Company has a limited number of leases subject to this ASU and is currently evaluating the impact of the adoption on its consolidated financial statements.

ASU 2016-13, Financial Instruments – Credit Losses (Topic 326)

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments – Credit Losses (Topic 326)" to provide more useful information about the expected credit losses on financial instruments. Current GAAP delays the recognition of credit losses until it is probable a loss has been incurred. The update will require a financial asset measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net income. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses. However, the amendments would limit the amount of the allowance to the amount by which fair value is below amortized cost. The measurement of credit losses on available-for-sale securities is similar under current GAAP, but the update requires the use of the allowance account through which amounts can be reversed, rather than through an irreversible write-down. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted beginning after December 15, 2018. Upon adoption, the update will be applied using the modified-retrospective approach, by which a cumulative-effect adjustment will be made to retained earnings as of the beginning of the first reporting period presented. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities

In March 2017, the FASB issued ASU 2017-08, "Premium Amortization on Purchased Callable Debt Securities," which shortens the amortization period of the premium for certain callable debt securities, from the contractual maturity date to the earliest call date. This ASU is effective in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, including in an interim period. Upon adoption, the update will be applied on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period presented. The Company does not expect the adoption of ASU 2017-08 to have a material impact on its financial statements.

7

There are no other prospective accounting standards which, upon their effective date, would have a material impact on the Company's consolidated financial statements.

Available-for-sale securities in a loss position

The Company regularly reviews all available-for-sale securities with unrealized losses to assess whether the decline in the securities’ fair value is deemed to be an other-than-temporary impairment ("OTTI"). The Company considers a number of factors in completing its OTTI review, including the length of time and the extent to which fair value

8

has been below cost and the financial condition of an issuer. In addition to specific issuer information, the Company also evaluates the current market and interest rate environment. Generally, a change in a security’s value caused by a change in the market or interest rate environment does not constitute an OTTI, but rather a temporary decline in fair value.

For fixed maturities, the Company considers whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before recovery, the credit quality of the issuer and the ability to recover all amounts outstanding when contractually due. When assessing whether it intends to sell a fixed-maturity security or if it is likely to be required to sell a fixed-maturity security before recovery of its amortized cost, the Company evaluates facts and circumstances including, but not limited to, decisions to reposition the investment portfolio, potential sales of investments to meet cash flow needs and potential sales of investments to capitalize on favorable pricing. For equity securities prior to the adoption of ASU 2016-01, the Company considered the near-term prospects of an issuer and its ability and intent to hold the security for a period of time sufficient to allow for anticipated recovery.

For fixed maturities where a decline in fair value is considered to be other-than-temporary and the Company intends to sell the security, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, an impairment is recognized in net income based on the fair value of the security at the time of assessment, resulting in a new cost basis for the security. If the decline in fair value of a fixed-maturity security below its amortized cost is considered to be other-than-temporary based upon other considerations, the Company compares the estimated present value of the cash flows expected to be collected to the amortized cost of the security. The extent to which the estimated present value of the cash flows expected to be collected is less than the amortized cost of the security represents the credit-related portion of the OTTI, which is recognized in net income, resulting in a new cost basis for the security. Any remaining decline in fair value represents the noncredit portion of the OTTI, which is recognized in other comprehensive income. For equity securities prior to the adoption of ASU 2016-01, a decline in fair value that was considered to be other-than-temporary was recognized in net income based on the fair value of the security at the time of assessment, resulting in a new cost basis for the security.

The following tables summarize gross unrealized losses and fair value for available-for-sale securities by length of time that the securities have continuously been in an unrealized loss position:

At September 30, 2018, the Company held 354 fixed-maturity securities in an unrealized loss position with a total estimated fair value of $363.9 million and gross unrealized losses of $8.9 million. Of these securities, 138 were in a continuous unrealized loss position for greater than one year. As discussed above, the Company regularly reviews all fixed-maturity securities within its investment portfolio to determine whether any impairment has occurred. Unrealized losses were caused by interest rate changes or other market factors and were not credit-specific issues. At September 30, 2018, 86.3% of the Company’s fixed-maturity securities were rated "A-" or better and all of the Company’s fixed-maturity securities made expected coupon payments under the contractual terms of the securities. Management concluded that there were no other-than-temporary impairments from fixed-maturity securities with unrealized losses for the nine months ended September 30, 2018.

At December 31, 2017, the Company held 195 fixed-maturity securities in an unrealized loss position with a total estimated fair value of $203.4 million and gross unrealized losses of $2.2 million. Of those securities, 126 were in a continuous unrealized loss position for greater than one year. Unrealized losses were caused by interest rate changes or other market factors and were not credit-specific issues. At December 31, 2017, 91.1% of the Company’s fixed-maturity securities were rated "A-" or better and all of the Company’s fixed-maturity securities made expected coupon payments under the contractual terms of the securities. At December 31, 2017, the Company held 13 securities in its equity portfolio with a total estimated fair value of $10.8 million and gross unrealized losses of $0.2 million. None of these securities were in a continuous unrealized loss position for greater than one year. Based on its review, the Company concluded that were no other-than-temporary impairments from fixed-maturity or equity securities with unrealized losses for the year ended December 31, 2017.

For the three and nine months ended September 30, 2017, the changes in net unrealized gains for fixed-maturity securities were $1.4 million and $4.9 million and the changes in net unrealized gains for equity securities was $1.1 million and $2.6 million, respectively.

Insurance – statutory deposits

The Company had invested assets with a carrying value of $6.9 million and $7.1 million on deposit with state regulatory authorities at September 30, 2018 and December 31, 2017, respectively.

Payable for investments purchased

The Company recorded a payable for investments purchased, not yet settled, of $10.2 million at September 30, 2018 and $1.0 million at December 31, 2017. The payable balances were included in the "other liabilities" line item of the balance sheet and treated as non-cash transactions for purposes of cash flow presentation. 

3.     Fair value measurements

Fair value was estimated for each class of financial instrument for which it was practical to estimate fair value. Fair value is defined as the price in the principal market that would be received for an asset to facilitate an orderly transaction between market participants on the measurement date. Market participants are assumed to be independent, knowledgeable, able and willing to transact an exchange and not acting under duress. Fair value hierarchy disclosures are based on the quality of inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and

12

the lowest priority to unobservable inputs (Level 3 measurements). Adjustments to transaction prices or quoted market prices may be required in illiquid or disorderly markets in order to estimate fair value.

The three levels of the fair value hierarchy are defined as follows:

Level 1 - Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities traded in active markets.

Level 2 - Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market-corroborated inputs.

Level 3 - Inputs to the valuation methodology are unobservable for the asset or liability and are significant to the fair value measurement.

Fair values of the Company's investment portfolio are estimated using unadjusted prices obtained by its investment manager from third party pricing services, where available. For securities where the Company is unable to obtain fair values from a pricing service or broker, fair values are estimated using information obtained from the Company's investment manager. Management performs several procedures to ascertain the reasonableness of investment values included in the condensed consolidated financial statements including 1) obtaining and reviewing internal control reports from the Company's investment manager that obtains fair values from third party pricing services, 2) discussing with the Company's investment manager its process for reviewing and validating pricing obtained from outside pricing services and 3) reviewing the security pricing received from the Company's investment manager and monitoring changes in unrealized gains and losses. The Company has evaluated the various types of securities in its investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs.

The following tables present the balances of assets measured at fair value on a recurring basis as of September 30, 2018 and December 31, 2017, by level within the fair value hierarchy.

There were no transfers into or out of Level 1 and Level 2 during the nine months ended September 30, 2018. There were no assets or liabilities measured at fair value on a nonrecurring basis as of September 30, 2018 or December 31, 2017.

Due to the relatively short-term nature of cash and cash equivalents, short-term investments, receivables and payables, their carrying amounts are reasonable estimates of fair value.

Salaries, bonus and employee benefits expenses were $15.6 million and $13.7 million for the nine months ended September 30, 2018 and 2017, respectively.

6.    Stock-based compensation

On July 27, 2016, the Kinsale Capital Group, Inc. 2016 Omnibus Incentive Plan (the "2016 Incentive Plan") became effective. The 2016 Incentive Plan provides for grants of stock options, stock appreciation rights, restricted stock, other stock-based awards and other cash-based awards to directors, officers and other employees, as well as independent contractors or consultants providing consulting or advisory services to the Company. The number of shares of common stock available for issuance under the 2016 Incentive Plan may not exceed 2,073,832. The total compensation cost that has been charged against income for share-based compensation arrangements was $1.1 million and $0.5 million for the nine months ended September 30, 2018 and 2017, respectively.

Restricted Stock Awards

During the nine months ended September 30, 2018, the Board of Directors approved, and the Company granted, restricted stock awards under the 2016 Incentive Plan. The restricted stock awards were valued on the date of grant and will vest over a period of one to four years corresponding to the anniversary date of the grants. The fair value of restricted stock awards was determined based on the closing trading price of the Company’s shares on the grant date or, if no shares were traded on the grant date, the last preceding date for which there was a sale of shares. Except for restrictions placed on the transferability of restricted stock, holders of unvested restricted stock have full stockholder’s rights, including voting rights and the right to receive cash dividends. Unvested shares of restricted stock awards and accrued dividends, if any, are forfeited upon the termination of service to or employment with the Company.

15

A summary of all restricted stock activity under the equity compensation plans for the nine months ended September 30, 2018 is as follows:

	For the Nine Months Ended  September 30, 2018
	Number of Shares		Weighted Average Grant Date Fair Value per Share
Non-vested outstanding at the beginning of the period	—		$	—
Granted	94,270		$	52.99
Vested	—		$	—
Forfeited	(1,247	)	$	53.60
Non-vested outstanding at the end of the period	93,023		$	52.98

As of September 30, 2018, the Company had $4.4 million of total unrecognized stock-based compensation expense expected to be charged to earnings over a weighted-average period of 3.6 years.

Stock Options

On July 27, 2016, the Board of Directors approved, and the Company granted, 1,036,916 stock options with an exercise price equal to the Initial Public Offering price of $16.00 per share and a weighted-average grant-date fair value of $2.71 per share. The options have a maximum contractual term of 10 years and vest in 4 equal annual installments following the date of the grant.

The value of the options granted was estimated at the date of grant using the Black-Scholes pricing model using the following assumptions:

Risk-free rate of return	1.26	%
Dividend yield	1.25	%
Expected share price volatility(1)	18.50	%
Expected life in years(2)	6.3 years

⁽¹⁾ Expected volatility was based on the Company’s competitors within the industry.

⁽²⁾ Expected life was calculated using the simplified method, which was an average of the contractual term of the option and its ordinary vesting period, as the Company did not have sufficient historical data for determining the expected term of our stock option awards.

A summary of option activity as of September 30, 2018, and changes during the period then ended is presented below:

	Number of Shares		Weighted-average exercise price		Weighted-average remaining years of contractual term	Aggregate intrinsic value (in thousands)
Outstanding at January 1, 2018	930,440		$	16.00
Granted	—		—

Exercisable at September 30, 2018	355,487		$	16.00	7.8	$	17,014

The total intrinsic value of options exercised was $4.0 million and $1.3 million during the nine months ended September 30, 2018 and 2017, respectively. As of September 30, 2018, the Company had $1.2 million of total unrecognized stock-based compensation expense expected to be charged to earnings over a weighted-average period of 1.8 years.

8. Income taxes

On December 22, 2017, the President of the United States signed into law the TCJA. The legislation significantly changed U.S. tax law by, among other things, lowering corporate income tax rates from 35% to 21% effective January 1, 2018, and modifying the manner in which property and casualty insurance loss reserves are computed for federal income tax purposes. The Company records a deduction for unpaid losses and loss adjustment expenses when computing its taxable income. Prior to the new legislation, the deduction was discounted using interest rates and loss payment patterns prescribed by the U.S. Treasury. The TCJA changed the prescribed interest rates, which are now based on corporate bond yield curves, and extended the applicable time periods for the loss payment pattern period for long-tailed lines of business. Beginning in 2018, a transition rule will spread the adjustments related to pre-effective-date losses and loss adjustment expenses over the next eight years.

U.S. GAAP requires companies to recognize the effect of tax law changes in the period of enactment. The SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the TCJA. The TCJA did not specify the application of certain elements of the legislation and the U.S. Treasury has yet to issue interpretive guidance to specify the loss payment patterns and the corporate bond yield curve under the new law for 2018. The Company recognized provisional tax amounts of $3.5 million related to the transition adjustment for loss discounting, which was included in its components of deferred tax assets and liabilities as part of its consolidated financial statements for the year ended December 31, 2017. The ultimate impact may differ from these provisional amounts due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, and actions the Company may take as a result of the TCJA. During the nine months ended September 30, 2018, there were no changes to these amounts and no measurement period adjustments were recorded. The accounting is expected to be complete when the U.S. Treasury issues further guidance or within the measurement period that ends in the fourth quarter of 2018.

The Company uses the estimated annual effective tax rate method for calculating its tax provision in interim periods, which represents the Company's best estimate of the effective tax rate expected for the full year. The estimated annual effective tax rate typically differs from the U.S. statutory tax rate primarily as a result of tax-exempt investment income and any discrete items recognized during the period. The Company's effective tax rates were 15.3% and 20.1% for the three months ended September 30, 2018 and 2017, respectively. The decrease in the effective tax rate in the third quarter of 2018 compared to the third quarter of 2017 was primarily due to the impact of the TCJA, which lowered the U.S. statutory tax rate from 35% to 21% starting January 1, 2018, offset in part by a larger percentage of tax benefits in the prior-year period from stock options exercised and tax-exempt interest income relative to pre-tax income. The Company's effective tax rates were 17.1% and 30.5% for the nine months ended September 30, 2018 and 2017, respectively. The decrease in the effective tax rate for the nine months ended September 30, 2018 compared to the same period in the prior year was primarily due to the impact of the TCJA.

Reinsurance recoverable on unpaid losses	63,521			45,949
Gross reserves for unpaid losses and loss adjustment expenses, end of period	$	365,814		$	310,934

During the nine months ended September 30, 2018, the reserves for unpaid losses and loss adjustment expenses held at December 31, 2017 developed favorably by $5.7 million. The favorable development was primarily attributable to the 2017 accident year of $4.8 million and the 2016 accident year of $3.3 million, which resulted from reported losses emerging at a lower level than expected. This favorable development was offset in part by adverse development of $2.4 million from the 2011 through 2015 accident years .

During the nine months ended September 30, 2017, the reserves for unpaid losses and loss adjustment expenses held at December 31, 2016 developed favorably by $11.8 million. The favorable development was attributable primarily to the 2016 accident year of $8.6 million, the 2015 accident year of $4.8 million and the 2014 accident year of $1.8 million, which was due to reported losses emerging at a lower level than expected. This favorable development was offset in part by adverse development of $3.4 million from the 2011 through 2013 accident years.

Multi-line quota share reinsurance

Effective January 1, 2017, the Company commuted its multi-line quota share treaty ("MLQS") covering the period January 1, 2015 to December 31, 2015, which reduced reinsurance recoverables on unpaid losses by approximately $27.9 million. The commutation did not have any effect on the Company's results of operations or cash flows for the applicable period.

⁽¹⁾ Adoption of ASU 2016-01, "Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities," which was effective January 1, 2018, eliminated the available-for-sale classification for equity investments and required changes in unrealized gains and losses in the fair value of equity securities to be recognized in net income.

The sale of an available-for-sale fixed-maturity security results in amounts being reclassified from accumulated other comprehensive income to realized gains or losses in current period earnings. The related tax effect of the reclassification adjustment is recorded in income tax expense in current period earnings. See Note 2 for additional information.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The discussion and analysis below includes certain forward-looking statements that are subject to risks, uncertainties and other factors described in "Risk Factors" in the Annual Report on Form 10-K for the year ended December 31, 2017. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of many factors.

The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the full year ended December 31, 2018, or for any other future period. The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and the notes thereto included in Part I, Item 1 of this Quarterly Report, and in conjunction with our audited consolidated financial statements and the notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2017.

References to the "Company," "Kinsale," "we," "us," and "our" are to Kinsale Capital Group, Inc. and its subsidiaries, unless the context otherwise requires.

Overview

Founded in 2009, Kinsale is a specialty insurance company. Kinsale focuses exclusively on the excess and surplus lines ("E&S") market in the U.S., where we use our underwriting expertise to write coverages for hard-to-place small business risks and personal lines risks. We market these insurance products in all 50 states, the District of Columbia, the Commonwealth of Puerto Rico and the U.S. Virgin Islands, primarily through a network of independent insurance brokers.

We have one reportable segment, our Excess and Surplus Lines Insurance segment, which offers property and casualty ("P&C") insurance products through the E&S market. For the first nine months of 2018, the percentage breakdown of our gross written premiums was 91.7% casualty and 8.3% property. Our underwriting divisions include construction, small business, general casualty, energy, excess casualty, professional liability, life sciences, product liability, allied health, health care, commercial property, environmental, management liability, inland marine, public entity and commercial insurance. We also write a small amount of homeowners insurance in the personal lines market, which in aggregate represented 4.6% of our gross written premiums in the first nine months of 2018.

Components of our results of operations

Gross written premiums

Gross written premiums are the amount received or to be received for insurance policies written or assumed by us during a specific period of time without reduction for policy acquisition costs, reinsurance costs or other deductions. The volume of our gross written premiums in any given period is generally influenced by:

• New business submissions;

• Conversion of new business submissions into policies;

• Renewals of existing policies; and

• Average size and premium rate of bound policies.

We earn insurance premiums on a pro rata basis over the term of a policy. Our insurance policies generally have a term of one year. Net earned premiums represent the earned portion of our gross written premiums, less that portion of our gross written premiums that is ceded under our reinsurance agreements.

Ceded written premiums

Ceded written premiums are the amount of gross written premiums ceded to reinsurers. We enter into reinsurance contracts to limit our exposure to potential large losses. Ceded written premiums are earned over the reinsurance contract

22

period in proportion to the period of risk covered. The volume of our ceded written premiums is impacted by the level of our gross written premiums and any decision we make to increase or decrease retention levels.

Net investment income

Net investment income is an important component of our results of operations. We earn investment income on our portfolio of cash and invested assets. Our cash and invested assets are primarily comprised of fixed-maturity securities, and may also include cash and cash equivalents, equity securities and short-term investments. The principal factors that influence net investment income are the size of our investment portfolio and the yield on that portfolio. As measured by amortized cost (which excludes changes in fair value, such as from changes in interest rates), the size of our investment portfolio is mainly a function of our invested equity capital along with premiums we receive from our insureds less payments on policyholder claims.

Net investment gains (losses)

Net investment gains (losses) are a function of the difference between the amount received by us on the sale of a security and the security's amortized cost, the unrealized gains and losses on our equity portfolio, as well as any "other-than-temporary" impairments recognized in earnings.

Losses and loss adjustment expenses

Losses and loss adjustment expenses are a function of the amount and type of insurance contracts we write and the loss experience associated with the underlying coverage. In general, our losses and loss adjustment expenses are affected by:

• Frequency of claims associated with the particular types of insurance contracts that we write;

• Trends in the average size of losses incurred on a particular type of business;

• Mix of business written by us;

• Changes in the legal or regulatory environment related to the business we write;

• Trends in legal defense costs;

• Wage inflation; and

• Inflation in medical costs.

Losses and loss adjustment expenses are based on an actuarial analysis of the estimated losses, including losses incurred during the period and changes in estimates from prior periods. Losses and loss adjustment expenses may be paid out over a period of years.

Underwriting, acquisition and insurance expenses

Underwriting, acquisition and insurance expenses include policy acquisition costs and other underwriting expenses. Policy acquisition costs are principally comprised of the commissions we pay our brokers, net of ceding commissions we receive on business ceded under certain reinsurance contracts. Policy acquisition costs that are directly related to the successful acquisition of those policies are deferred. The amortization of such policy acquisition costs is charged to expense in proportion to premium earned over the policy life. Other underwriting expenses represent the general and administrative expenses of our insurance business including employment costs, telecommunication and technology costs, the costs of our lease, and legal and auditing fees.

Income tax expense

Currently all of our income tax expense relates to federal income taxes. Kinsale Insurance Company is generally not subject to income taxes in the states in which it operates; however, our non-insurance subsidiaries are subject to state income taxes. The amount of income tax expense or benefit recorded in future periods will depend on the jurisdictions in which we operate and the tax laws and regulations in effect.

Key metrics

We discuss certain key metrics, described below, which provide useful information about our business and the operational factors underlying our financial performance.

Underwriting income is a non-GAAP financial measure. We define underwriting income as pre-tax income, excluding net investment income, net investment gains and losses, and other income and expenses. See "—Reconciliation of non-GAAP financial measures" for a reconciliation of net income to underwriting income in accordance with GAAP.

Loss ratio, expressed as a percentage, is the ratio of losses and loss adjustment expenses to net earned premiums, net of the effects of reinsurance.

Expense ratio, expressed as a percentage, is the ratio of underwriting, acquisition and insurance expenses to net earned premiums.

Combined ratio is the sum of the loss ratio and the expense ratio. A combined ratio under 100% generally indicates an underwriting profit. A combined ratio over 100% generally indicates an underwriting loss.

Return on equity is net income expressed on an annualized basis as a percentage of average beginning and ending stockholders’ equity during the period. Our overall financial goal is to produce a return on equity in the mid-teens or higher over the long-term.

Net retention ratio is the ratio of net written premiums to gross written premiums.

⁽¹⁾ Underwriting income is a non-GAAP financial measure. See "—Reconciliation of non-GAAP financial measures" for a reconciliation of net income to underwriting income in accordance with GAAP.

Net income was $11.9 million for the three months ended September 30, 2018 compared to $4.2 million for the three months ended September 30, 2017, an increase of 184.2%. The increase in net income was due to lower catastrophe losses in the third quarter of 2018 compared to the third quarter of 2017. After-tax catastrophe losses incurred were $0.3 million in the third quarter of 2018 compared to $5.2 million in the third quarter of 2017. In addition, the third quarter of 2018 benefited from higher net investment returns, partially resulting from a new accounting pronouncement effective January 1, 2018, and a lower effective tax rate of 15.3%, resulting from the Tax Cuts and Jobs Act of 2017 ("TCJA").

Underwriting income was $8.4 million for the three months ended September 30, 2018 compared to $2.5 million for the three months ended September 30, 2017, an increase of 238.1%. The corresponding combined ratios were 84.6% for the three months ended September 30, 2018 compared to 94.5% for the three months ended September 30, 2017. As previously discussed, the increase in our underwriting income was principally due to lower catastrophe losses in the third quarter of 2018 compared to the third quarter of 2017.

Premiums

Our gross written premiums were $69.5 million for the three months ended September 30, 2018 compared to $55.6 million for the three months ended September 30, 2017, an increase of $13.9 million, or 25.0%. The increase in gross written premiums for the third quarter of 2018 over the same period last year was largely due to higher submissions activity from our brokers across most lines of business. The average premium on a policy written was approximately $7,700 in the third quarter of 2018 compared to approximately $8,000 in the third quarter of 2017. Excluding our personal lines insurance, which has a relatively low premium per policy written, the average premium on a policy written was approximately $10,300 for both the third quarter of 2018 and 2017.

Net written premiums increased by $10.9 million, or 23.1%, to $57.9 million for the three months ended September 30, 2018 from $47.1 million for the three months ended September 30, 2017. The increase in net written premiums for the third quarter of 2018 compared to the same period last year was primarily due to higher gross written premiums. The net retention ratio was 83.3% for the three months ended September 30, 2018 compared to 84.6% for the three months ended September 30, 2017.

Net earned premiums increased by $9.3 million, or 20.6%, to $54.3 million for the three months ended September 30, 2018 from $45.0 million for the three months ended September 30, 2017 due to growth in gross written premiums.

Loss ratio

The loss ratio was 59.1% for the three months ended September 30, 2018 compared to 70.1% for the three months ended September 30, 2017. The decrease in the loss ratio principally due to lower catastrophe losses for the third quarter of 2018 over the third quarter of 2017, offset in part by an increase in the loss ratio for the current accident year due to higher claims activity.

During the third quarter of 2018 and 2017, the overall favorable development of loss reserves for prior accident years resulted principally from reported losses emerging at lower levels than expected. During the third quarter of 2018, prior accident years developed favorably by $2.2 million, of which $2.3 million was attributable to accident year 2017 and $1.5 million was attributable to accident years 2012 through 2014. This favorable development was offset in part by adverse development from accident year 2015 of $1.7 million. During the third quarter of 2017, loss reserves for prior accident years developed favorably by $2.9 million, which was attributable to accident years 2014 to 2016 of $4.8 million. This favorable development was offset in part by adverse development in accident years 2011 through 2013 of $1.9 million.

Expense ratio

The expense ratio for the three months ended September 30, 2018 was slightly higher compared to the three months ended September 30, 2017. The following table summarizes the components of the expense ratio for the three months ended September 30, 2018 and 2017:

	Three Months Ended September 30,

Underwriting, acquisition and insurance expenses	$	13,850		25.5	%	$	10,989		24.4	%

The increase in the other underwriting expense ratio for the three months ended September 30, 2018 compared to the same period last year was due to higher variable and stock-based compensation costs. Variable compensation costs were lower in the third quarter of 2017 as a result of the hurricane losses, which adversely affected underwriting results during the quarter. Direct commissions paid as a percent of gross written premiums were 14.7% for the three months ended September 30, 2018 and September 30, 2017.

Investing results

Our net investment income increased by 47.7% to $4.1 million for the three months ended September 30, 2018 from $2.8 million for the three months ended September 30, 2017. The increase in the third quarter of 2018 compared to the same period last year was primarily due to growth in our investment portfolio balance generated from excess operating funds and higher gross investment returns as a result of a more favorable interest rate environment.

Our investment portfolio, excluding cash equivalents and unrealized gains and losses, had an annualized gross investment return of 3.0% for the three months ended September 30, 2018, compared to 2.6% for the three months ended September 30, 2017. As discussed previously, effective January 1, 2018, we adopted a new accounting standard which required changes in the fair value of equity investments to be recognized in net income. During the third quarter of 2018, we recognized unrealized gains of $1.8 million related to our equity investment portfolio.

We perform quarterly reviews of all available-for-sale securities within our investment portfolio to determine whether any other-than-temporary impairment has occurred. Management concluded that there were no other-than-temporary impairments from available-for-sale investments for the three months ended September 30, 2018 or 2017.

Income tax expense

Our income tax expense was $2.2 million for the three months ended September 30, 2018 compared to $1.1 million for the three months ended September 30, 2017. Our effective tax rate was approximately 15.3% for the three months ended September 30, 2018 compared to 20.1% for the three months ended September 30, 2017. For the third quarter of 2018, our effective tax rate reflected the TCJA, which among other provisions, lowered the federal corporate tax rate from 35% to 21% starting January 1, 2018. The decrease in the effective tax rate for the three months ended September 30, 2018 compared to the prior-year period was offset in part by a larger percentage of tax benefits in the prior-year period from stock options exercised and tax-exempt interest income relative to pre-tax income.

⁽¹⁾ Underwriting income is a non-GAAP financial measure. See "—Reconciliation of non-GAAP financial measures" for a reconciliation of net income to underwriting income in accordance with GAAP.

Net income was $29.3 million for the nine months ended September 30, 2018 compared to $19.0 million for the nine months ended September 30, 2017, an increase of 54.6%. The increase in net income for the first nine months of 2018 over the first nine months of 2017 was due to a number of factors, including lower catastrophe losses of $4.9 million, net of taxes, a lower effective tax rate of 17.1%, largely resulting from the TCJA, and higher net investment income. These factors were offset in part by lower net favorable development of loss reserves for prior accident years.

Underwriting income was $23.5 million for the nine months ended September 30, 2018 compared to $20.2 million for the nine months ended September 30, 2017, an increase of 16.5%. The corresponding combined ratios were 84.6% for the nine months ended September 30, 2018 compared to 84.3% for the nine months ended September 30, 2017. The increase in our underwriting income in the first nine months of 2018 compared to the first nine months of 2017, was due to a combination of lower catastrophe losses and higher net earned premiums, offset in part by lower net favorable development of loss reserves for prior accident years.

Premiums

Our gross written premiums were $203.4 million for the nine months ended September 30, 2018 compared to $166.2 million for the nine months ended September 30, 2017, an increase of $37.1 million, or 22.3%. The increase in gross written premiums for the first nine months of 2018 over the same period last year was due to higher submission activity across most lines of business. The average premium on a policy written was approximately $7,600 in the first nine months of 2018 compared to approximately $8,100 in the first nine months of 2017. Excluding our personal lines insurance, which has a relatively low premium per policy written, the average premium on a policy written was approximately $10,200 for the first nine months of 2018 and $10,600 for the first nine months of 2017. The decrease in the average premium per policy written was due to changes in the mix of business during the first nine months of 2018 compared to the same period last year.

Net written premiums increased by $32.9 million, or 23.3%, to $173.9 million for the nine months ended September 30, 2018 from $141.0 million for the nine months ended September 30, 2017. The increase in net written premiums for the first nine months of 2018 compared to the same period last year was primarily due to higher gross written premiums. The net retention ratio was 85.5% for the nine months ended September 30, 2018 compared to 84.8% for the nine months ended September 30, 2017. The increase in the net retention ratio was due to an increase in our retention on the excess casualty reinsurance treaty effective with the renewal on June 1, 2017 and a change in the mix of business.

Net earned premiums increased by $24.7 million, or 19.2%, to $153.3 million for the nine months ended September 30, 2018 from $128.5 million for the nine months ended September 30, 2017 due to growth in gross written premiums.

Loss ratio

The loss ratio was 59.3% for the nine months ended September 30, 2018 compared to 58.8% for the nine months ended September 30, 2017. The increase in the loss ratio in the first nine months of 2018 compared to the first nine months of 2017 was due to lower net favorable development of loss reserves for prior accident years, offset in part by lower catastrophe losses year over year.

During the first nine months of 2018 and 2017, the overall favorable development of loss reserves for prior accident years was primarily due to reported losses emerging at lower levels than expected. During the nine months ended September 30, 2018, prior accident years developed favorably by $5.7 million, of which $8.1 million was attributable to accident years 2016 and 2017. This favorable development was offset in part by adverse development from accident years 2011 through 2015 of $2.4 million. During the nine months ended September 30, 2017, loss reserves for prior accident years developed favorably by $11.8 million, which was largely attributable to accident years 2014 through 2016 of $15.2 million. This favorable development was offset in part by adverse development in the accident years 2011 through 2013 of $3.4 million.

The expense ratio was 25.3% for the nine months ended September 30, 2018 compared to 25.5% for the nine months ended September 30, 2017. The decrease in the other underwriting expense ratio for the nine months ended September 30, 2018 compared to the same period last year reflected the benefit of higher net earned premiums without a proportional increase in total other underwriting expenses from management's focus on controlling costs. Direct commissions paid as a percent of gross written premiums was 14.7% for the nine months ended September 30, 2018 and 14.9% for the nine months ended September 30, 2017.

Other expenses, net

Other expenses of $0.4 million for the nine months ended September 30, 2017 were comprised of expenses related to the secondary offering of our common stock in May 2017.

Investing results

Our net investment income increased by 48.3% to $11.1 million for the nine months ended September 30, 2018 from $7.5 million for the nine months ended September 30, 2017. This increase in the first nine months of 2018 compared to the same period last year was primarily due to growth in our investment portfolio balance generated from excess operating funds and higher gross investment returns, as a result of a more favorable interest rate environment, and higher dividends.

NM - Percentage change not meaningful

Our investment portfolio, excluding cash equivalents and unrealized gains and losses, had an annualized gross investment return of 2.9% for the nine months ended September 30, 2018, compared to 2.4% for the nine months ended September 30, 2017. As discussed previously, effective January 1, 2018, we adopted a new accounting standard which required changes in the fair value of equity investments to be recognized in net income. During the first nine months of 2018, we recognized unrealized gains of $0.6 million related to our equity portfolio.

We perform quarterly reviews of all available-for-sale securities within our investment portfolio to determine whether any other-than-temporary impairment has occurred. Management concluded that there were no other-than-temporary impairments from available-for-sale investments for the nine months ended September 30, 2018 or 2017.

Income tax expense

Our income tax expense was $6.0 million for the nine months ended September 30, 2018 compared to $8.3 million for the nine months ended September 30, 2017. Our effective tax rate was approximately 17.1% for the nine months ended September 30, 2018 compared to 30.5% for the nine months ended September 30, 2017. For the first nine months of 2018, our effective tax rate reflected the TCJA, which among other provisions, lowered the federal corporate tax rate from 35% to 21% starting January 1, 2018.

Return on equity

Our annualized return on equity was 15.8% for the nine months ended September 30, 2018 compared to 11.5% for the nine months ended September 30, 2017. The increase in annualized return on equity for the nine months ended September 30, 2018 compared to the prior-year period was due to a number of factors, including lower catastrophe losses incurred, the lower income tax rate resulting from the TCJA and higher overall returns on the investment portfolio, offset in part by lower net favorable development of loss reserves in prior accident years.

Liquidity and capital resources

Sources and uses of funds

We are organized as a Delaware holding company with our operations primarily conducted by our wholly-owned insurance subsidiary, Kinsale Insurance Company, which is domiciled in Arkansas. Accordingly, we may receive cash through (1) loans from banks and other third parties, (2) issuance of equity and debt securities, (3) corporate service fees from our insurance subsidiary, (4) payments from our subsidiaries pursuant to our consolidated tax allocation agreement and other transactions, and (5) dividends from our insurance subsidiary. We may use the proceeds from these sources to contribute funds to Kinsale Insurance Company in order to support premium growth, reduce our reliance on reinsurance, pay dividends and taxes and for other business purposes.

We receive corporate service fees from Kinsale Insurance Company to reimburse us for most of the operating expenses that we incur. Reimbursement of expenses through corporate service fees is based on the actual costs that we expect to incur with no mark-up above our expected costs.

Management believes that the Company has sufficient liquidity available both in Kinsale and in its insurance subsidiary, Kinsale Insurance Company, as well as in its other operating subsidiaries, to meet its operating cash needs and obligations and committed capital expenditures for the next 12 months.

Cash flows

Our most significant source of cash is from premiums received from our insureds, which, for most policies, we receive at the beginning of the coverage period. Our most significant cash outflow is for claims that arise when a policyholder incurs an insured loss. Because the payment of claims occurs after the receipt of the premium, often years later, we invest the cash in various investment securities that earn interest and dividends. We also use cash to pay commissions to brokers, as well as to pay for ongoing operating expenses such as salaries, rent and taxes. As described under "—Reinsurance" below, we use reinsurance to manage the risk that we take on our policies. We cede, or pay out, part of the premiums we receive to our reinsurers and collect cash back when losses subject to our reinsurance coverage are paid.

The timing of our cash flows from operating activities can vary among periods due to the timing by which payments are made or received. Some of our payments and receipts, including loss settlements and subsequent reinsurance receipts, can be significant, so their timing can influence cash flows from operating activities in any given period. Management believes that cash receipts from premiums, proceeds from investment sales and redemptions and investment income are sufficient to cover cash outflows in the foreseeable future.

Our cash flows for the nine months ended September 30, 2018 and 2017 were:

	Nine Months Ended September 30,
	2018			2017
	(in thousands)
Cash and cash equivalents provided by (used in):
Operating activities	$	78,406		$	64,547
Investing activities	(92,542		)	(15,797		)
Financing activities	(2,867		)	(2,818		)
Change in cash and cash equivalents	$	(17,003	)	$	45,932

Net cash provided by operating activities was approximately $78.4 million for the ninemonths ended September 30, 2018, compared to $64.5 million for the same period in 2017. This increase was largely driven by premium volume, the timing of claim payments, reinsurance recoveries, and changes in operating assets and liabilities.

Net cash used in investing activities was $92.5 million for the nine months ended September 30, 2018, compared to $15.8 million for the nine months ended September 30, 2017. Net cash used in investing activities during the first nine months of 2018 reflected purchases of fixed-maturity securities of $170.9 million, comprised principally of corporate bonds and asset-backed securities. During the first nine months of 2018, we received proceeds of $85.7 million from maturities and

32

sales of fixed-maturity securities. Purchases of equity securities were $8.8 million, largely exchange traded funds ("ETFs"), and we received $2.0 million from the sale of an intermediate-term bond ETF and non-redeemable preferred stocks for the nine months ended September 30, 2018.

Cash used in investing activities during the first nine months of 2017 reflected selective purchases of fixed-income securities of $70.1 million, principally municipal bonds and asset-backed securities. In addition, we purchased $20.9 million of equity securities during the first nine months of 2017, which included $11.4 million of non-redeemable preferred stock purchased during the third quarter of 2017. During the first nine months of 2017, we received proceeds of $75.3 million from sales and maturities of fixed income securities.

During the nine months ended September 30, 2018, cash used in financing activities reflected dividends paid of $0.21 per common share, or $4.4 million in aggregate. During the nine months ended September 30, 2017, cash used in financing activities primarily reflected dividends paid of $0.18 per common share, or $3.8 million in aggregate. Proceeds received from the exercise of stock options were $1.6 million and $1.0 million for the nine months ended September 30, 2018 and 2017, respectively.

Reinsurance

We enter into reinsurance contracts primarily to limit our exposure to potential large losses. Reinsurance involves an insurance company transferring ("ceding") a portion of its exposure on a risk to another insurer, the reinsurer. The reinsurer assumes the exposure in return for a portion of the premium. Our reinsurance is primarily contracted under quota-share reinsurance contracts and excess of loss contracts. In quota-share reinsurance, the reinsurer agrees to assume a specified percentage of the ceding company's losses arising out of a defined class of business in exchange for a corresponding percentage of premiums, net of a ceding commission. In excess of loss reinsurance, the reinsurer agrees to assume all or a portion of the ceding company's losses, in excess of a specified amount. Under excess of loss reinsurance, the premium payable to the reinsurer is negotiated by the parties based on their assessment of the amount of risk being ceded to the reinsurer because the reinsurer does not share proportionately in the ceding company's losses.

We use facultative reinsurance coverage on a limited basis. Facultative coverage refers to a reinsurance contract on individual risks as opposed to a group or class of business. It is used for a variety of reasons, including supplementing the limits provided by the treaty coverage or covering risks or perils excluded from treaty reinsurance.

The following is a summary of our significant reinsurance programs as of September 30, 2018:

Line of Business Covered	Company Policy Limit	Reinsurance Coverage	Company Retention
Property - per risk	Up to $10.0 million per risk	$9.0 million excess of $1.0 million	$1.0 million per occurrence
Property - catastrophe (1)	N/A	$45.0 million excess of $5.0 million	$5.0 million per catastrophe
Primary casualty (2)	Up to $10.0 million per occurrence	$9.0 million excess of $1.0 million	$1.0 million per occurrence
Excess casualty (3)	Up to $10.0 million per occurrence	Variable quota share	$1.5 million per occurrence except as described in note (3) below

(1) Our property catastrophe reinsurance reduces the financial impact of a catastrophe event involving multiple claims and policyholders. Our property catastrophe reinsurance includes a reinstatement provision which requires us to pay reinstatement premiums after a loss has occurred in order to preserve coverage. Including the reinstatement provision, the maximum aggregate loss recovery limit is $90 million and is in addition to the per-occurrence coverage provided by our facultative and other treaty coverages. 

(2) Reinsurance is not applicable to any individual policy with a per occurrence limit of $1.0 million or less.

33

(3) For policies with a per occurrence limit higher than $1.0 million, the quota-share ceding percentage varies such that the retention is always $1.5 million or less. For example, for a $2.0 million limit excess policy, our retention would be 75%, whereas for a $10.0 million limit excess policy, our retention would be 15%. For policies for which we also write an underlying primary limit, the retention on the primary and excess policy combined would not exceed $1.5 million.

At each renewal, we consider any plans to change the underlying insurance coverage we offer, as well as updated loss activity, the level of our capital and surplus, changes in our risk appetite and the cost and availability of reinsurance treaties.

Reinsurance contracts do not relieve us from our obligations to policyholders. Failure of the reinsurer to honor its obligations could result in losses to us, and therefore, we establish allowances for amounts considered uncollectible. In formulating our reinsurance programs, we are selective in our choice of reinsurers and we consider numerous factors, the most important of which are the financial stability of the reinsurer, its history of responding to claims and its overall reputation. In an effort to minimize our exposure to the insolvency of our reinsurers, we review the financial condition of each reinsurer annually. In addition, we continually monitor for rating downgrades involving any of our reinsurers. At September 30, 2018, all reinsurance contracts that our insurance subsidiary was a party to were with companies with A.M. Best ratings of "A" (Excellent) or better. As of September 30, 2018, we have never had a loss for uncollectible reinsurance.

Ratings

Kinsale Insurance Company has a financial strength rating of "A-" (Excellent) with a positive outlook from A.M. Best. A.M. Best assigns 16 ratings to insurance companies, which currently range from "A++" (Superior) to "F" (In Liquidation). "A-" (Excellent) is the fourth highest rating issued by A.M. Best. The "A-" (Excellent) rating is assigned to insurers that have, in A.M. Best's opinion, an excellent ability to meet their ongoing obligations to policyholders. This rating is intended to provide an independent opinion of an insurer's ability to meet its obligation to policyholders and is not an evaluation directed at investors.

The financial strength ratings assigned by A.M. Best have an impact on the ability of the insurance companies to attract and retain agents and brokers and on the risk profiles of the submissions for insurance that the insurance companies receive. The "A-" (Excellent) rating obtained by Kinsale Insurance Company is consistent with our business plan and allows us to actively pursue relationships with the agents and brokers identified in our marketing plan.

Financial condition

Stockholders' equity

At September 30, 2018, total stockholders' equity was $257.9 million and tangible stockholders' equity was $255.1 million, compared to total stockholders' equity of $238.2 million and tangible stockholders' equity $235.4 million at December 31, 2017. The increases in both total and tangible stockholders' equity over the prior year-end balances were primarily due to profits generated during the period and activity related to stock-based compensation plans, offset in part by an increase in unrealized losses on investments, net of taxes, and payment of dividends.

Tangible stockholders’ equity is a non-GAAP financial measure. We define tangible stockholders’ equity as stockholders’ equity less intangible assets, net of deferred taxes. Our definition of tangible stockholders’ equity may not be comparable to that of other companies, and it should not be viewed as a substitute for stockholders’ equity calculated in accordance with GAAP. We use tangible stockholders' equity internally to evaluate the strength of our balance sheet and to compare returns relative to this measure.

Stockholders' equity at September 30, 2018 and December 31, 2017, reconciles to tangible stockholders' equity as follows:

Investment portfolio

AtSeptember 30, 2018, our cash and invested assetsof $634.2 millionconsisted of fixed-maturity securities, cash and cash equivalents and equity securities. At September 30, 2018, the majority of the investment portfolio was comprised of fixed-maturity securities of $508.0 million that were classified as available-for-sale. Available-for-sale investments are carried at fair value with unrealized gains and losses on these securities, net of applicable taxes, reported as a separate component of accumulated other comprehensive income. At September 30, 2018, we also held $64.7 million of cash and cash equivalents and $61.4 million of equity securities, which are comprised of ETFs and non-redeemable preferred stock. Effective January 1, 2018, we adopted a new accounting standard ASU 2016-01, "Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities," which eliminated the available-for-sale classification for equity securities and required changes in unrealized gains and losses in fair value of these investments to be recognized in net income. Our fixed-maturity securities, including cash equivalents, had a weighted average duration of 4.0 years at September 30, 2018 compared to 3.9 years at December 31, 2017 and an average rating of "AA" at September 30, 2018 and December 31, 2017.

At September 30, 2018 and December 31, 2017, the amortized cost and fair value on fixed-maturity securities were as follows:

Restricted investments

In order to conduct business in certain states, we are required to maintain letters of credit or assets on deposit to support state-mandated insurance regulatory requirements and to comply with certain third-party agreements. Assets held on deposit or in trust accounts are primarily in the form of high-grade securities. The fair value of our restricted assets was$6.9 million at September 30, 2018 and $7.1 million at December 31, 2017.

Off-balance sheet arrangements

We do not have any material off-balance sheet arrangements at September 30, 2018.

Reconciliation of non-GAAP financial measures

Reconciliation of underwriting income

Underwriting income is a non-GAAP financial measure that we believe is useful in evaluating our underwriting performance without regard to investment income. Underwriting income represents the pre-tax profitability of our insurance operations and is derived by subtracting losses and loss adjustment expenses and underwriting, acquisition and insurance expenses from net earned premiums. We use underwriting income as an internal performance measure in the management of our operations because we believe it gives us and users of our financial information useful insight into our results of operations and our 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.

Net income for the three and nine months ended September 30, 2018 and 2017, reconciles to underwriting income as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,

Critical accounting estimates

We identified the accounting estimates which are critical to the understanding of our financial position and results of operations. Critical accounting estimates are defined as those estimates that are both important to the portrayal of our financial condition and results of operations and require us to exercise significant judgment. We use significant judgment concerning future results and developments in applying these critical accounting estimates and in preparing our consolidated financial statements. These judgments and estimates affect our reported amounts of assets, liabilities, revenues and expenses and the disclosure of our material contingent assets and liabilities. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements. We evaluate our estimates regularly using information that we believe to be relevant. Our critical accounting policies and estimates are described in our annual consolidated financial statements and the related notes in our Annual Report on Form 10-K for the year ended December 31, 2017.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of economic losses due to adverse changes in the estimated fair value of a financial instrument as the result of changes in interest rates, equity prices, foreign currency exchange rates and commodity prices.Our primary market risks have been equity price risk associated with investments in equity securities and interest rate risk associated with investments in fixed maturities. We do not have any material exposure to foreign currency exchange rate risk or commodity risk.

There have been no material changes in market risk from the information provided in our Annual Report on Form 10-K for the year ended December 31, 2017.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports we file under the Securities Exchange Act of 1934 (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), as appropriate, to allow timely decisions regarding required financial disclosure.

As of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures defined under Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based upon this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

During the third quarter of 2018, we implemented a new general ledger system resulting in a material change in internal control over financial reporting. The new system was used in preparing third quarter 2018 financial information. Pre-implementation testing and post-implementation reviews were conducted by management to ensure that internal controls surrounding the system implementation process, the application, and the closing process were properly designed to prevent material financial statement errors. Such procedures included the review of required documents, user acceptance testing, change management procedures, assessment of access controls, data migration processes and reconciliations, application interface testing, and month-end reconciliations.

Inherent Limitations on Effectiveness of Controls

The effectiveness of any system of controls and procedures is subject to certain limitations, and, as a result, there can be no assurance that our controls and procedures will detect all errors or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system will be attained.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are party to legal proceedings which arise in the ordinary course of business. We believe that the outcome of such matters, individually and in the aggregate, will not have a material adverse effect on our consolidated financial position.

Item 1A. Risk Factors

There have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2017.
