NOTES TO UNAUDITED CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A. DESCRIPTION OF BUSINESS

RLI Corp. (the Company) is an insurance holding company that was organized in 1965. As reported in previous SEC filings, RLI Corp. changed its state of incorporation from the State of Illinois to the State of Delaware on May 4, 2018 (the Reincorporation). The Reincorporation was effected by merging RLI Corp., an Illinois corporation (RLI Illinois) into RLI Corp., a Delaware corporation (RLI Delaware). Each outstanding share of RLI Illinois common stock, which had a par value of $1.00 per share, was automatically converted into one outstanding share of RLI Delaware common stock, with a par value of $0.01 per share. In order to reflect the new par value of common stock on the balance sheet, a $66.5 million reclassification from common stock to paid-in-capital was made during the second quarter of 2018. For more information on the Reincorporation, see RLI Corp.’s Form 8-K filed on May 7, 2018.

B. BASIS OF PRESENTATION

The unaudited condensed consolidated interim financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) for interim financial reporting and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. As such, these unaudited condensed consolidated interim financial statements should be read in conjunction with our 2018 Annual Report on Form 10-K. Management believes that the disclosures are adequate to make the information presented not misleading, and all normal and recurring adjustments necessary to present fairly the financial position at June 30, 2019 and the results of operations of RLI Corp. and subsidiaries for all periods presented have been made. The results of operations for any interim period are not necessarily indicative of the operating results for a full year. Certain reclassifications were made to 2018 to conform to the classifications used in the current year.

The preparation of the unaudited condensed consolidated interim financial statements requires management to make estimates and assumptions relating to the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated interim financial statements and the reported amounts of revenue and expenses during the period. These estimates are inherently subject to change and actual results could differ significantly from these estimates.

C. ADOPTED ACCOUNTING STANDARDS

ASU 2016-02, Leases (Topic 842)

ASU 2016-02 was issued to improve the financial reporting of leasing transactions. Under previous guidance for lessees, leases were only included on the balance sheet if certain criteria, classifying the agreement as a capital lease, were met. This update requires the recognition of a right-of-use asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. For operating leases, the asset and liability are expensed over the lease term on a straight-line basis, with all cash flows included in the operating section of the statement of cash flows. For finance leases, interest on the lease liability is recognized separately from the amortization of the right-of-use asset in the statement of earnings and the repayment of the principal portion of the lease liability is classified as a financing activity while the interest component is included in the operating section of the statement of cash flows.

We adopted ASU 2016-02, ASU 2018-10 Codification Improvements to Topic 842: Leases and ASU 2018-11 Leases (Topic 842): Targeted Improvements on January 1, 2019. We applied the standards using the alternative transition method provided by ASU 2018-11 under which leases were recognized at the date of adoption and a cumulative-effective adjustment to the opening balance of retained earnings would have been recognized in the period of adoption. As the standard did not have an impact on our net earnings, no adjustment to the opening balance of retained earnings was required. As of June 30, 2019, $24.4 million of right-of-use assets and $26.6 million of lease liabilities were included in the other assets and other liabilities line items of the balance sheet, respectively, as a result of the adoption of this update. We implemented controls for the adoption of the standard and the ongoing monitoring of the right-of-use asset and lease liability, but they did not materially affect our internal control over financial reporting.

7

ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities

Under previous guidance, the amortization period for callable debt securities held at a premium was generally the contractual life of the instrument. However, if an entity had a large number of similar loans, it could consider estimates of future principal prepayments. For those who chose not to incorporate an estimate of future prepayments, ASU 2017-08 shortens the amortization period for premium on debt securities to the earliest call date, rather than the maturity date, to align the amortization method with how the securities are quoted, priced and traded. After the earliest call date, if the call option is not exercised, the entity shall reset the effective yield using the payment terms of the debt security. Any excess of the amortized cost basis over the amount payable will be amortized to the next call date or to maturity if there are no other call dates. The method of accounting for a discount does not change and will continue to be amortized over the life of the bond.

We adopted ASU 2017-08 on January 1, 2019 using a modified-retrospective approach. As we had been incorporating estimates of future principal prepayments when calculating the effective yield for bonds carrying a premium under the old guidance, the adoption of this update did not have a material impact on our financial statements.

ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting

ASU 2018-07 was issued to simplify the accounting for share-based transactions by expanding the scope of Topic 718 from only being applicable to share-based payments to employees to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, nonemployee share-based transactions will be measured by estimating the fair value of the equity instruments at the grant date, taking into consideration the probability of satisfying performance conditions. We adopted ASU 2018-07 on January 1, 2019. Our long-term incentive plan limits the awards of share-based payments to employees and directors of the Company. As our share-based compensation expense to nonemployee directors was $0.3 million in the first six months of 2019, the standard did not have a material impact on our financial statements.

D. PROSPECTIVE ACCOUNTING STANDARDS

ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

ASU 2016-13 was issued to provide more decision-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, including reinsurance balances recoverable, to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net earnings. 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 in which the guidance is effective. This update will have the most impact on our available-for-sale fixed income portfolio and reinsurance balances recoverable. However, as our fixed income portfolio is weighted towards higher rated bonds (83.0 percent rated A or better at June 30, 2019) and we purchase reinsurance from financially strong reinsurers for which we already have an allowance for uncollectible reinsurance amounts, we do not expect that the effect of adoption will be material.

ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement

ASU 2018-13 modifies the disclosure requirements for assets and liabilities measured at fair value. The requirements to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements have all been removed. However, the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period must be disclosed along with the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements (or other quantitative information if it is more reasonable). Finally, for investments measured at net asset value, the requirements have been modified so that the timing of

8

liquidation and the date when restrictions from redemption might lapse are only disclosed if the investee has communicated the timing to the entity or announced the timing publicly.

This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. As the amendments are only disclosure related and we do not currently have any assets or liabilities that are measured based on Level 3 inputs, our financial statements will not be materially impacted by this update.

ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract

ASU 2018-15 requires a customer in a cloud computing arrangement (i.e. hosting arrangement) that is a service contract to follow the internal-use software guidance to determine which implementation costs to capitalize as assets or expense as incurred. Relevant implementation costs in the development stage are capitalized, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. Capitalized costs are expensed over the term of the hosting arrangement. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted. This update can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are currently evaluating how the adoption of this ASU will affect our financial statements.

Goodwill and intangible assets totaled $54.3 million and $54.5 million at June 30, 2019 and December 31, 2018, respectively, as detailed in the following table:

Goodwill and Intangible Assets		June 30,		December 31,
(in thousands)		2019		2018
Goodwill
Energy surety	$	25,706	$	25,706
Miscellaneous and contract surety		15,110		15,110
Small commercial		5,246		5,246
Total goodwill	$	46,062	$	46,062
Intangibles
State insurance licenses	$	7,500	$	7,500
Definite-lived intangibles, net of accumulated amortization of $3,266 at 6/30/19 and $3,062 at 12/31/18		768		972
Total intangibles	$	8,268	$	8,472
Total goodwill and intangibles	$	54,330	$	54,534

All definite-lived intangible assets are amortized against future operating results based on their estimated useful lives. Amortization of intangible assets was $0.1 million for the second quarter of 2019 and $0.2 million for the six-month period ended June 30, 2019, the same as for the comparable periods in 2018.

Annual impairment assessment was performed on our energy surety goodwill, miscellaneous and contract surety goodwill, small commercial goodwill and state insurance license indefinite-lived intangible asset during the second quarter of 2019. Based upon these reviews, none of the assets were impaired. In addition, as of June 30, 2019, there were no triggering events that would suggest an updated review was necessary on the above-mentioned goodwill and intangible assets.

Adverse loss experience triggered the need to test the medical professional liability reporting unit during the first quarter of 2018, which resulted in a $4.4 million non-cash impairment charge. A fair value for the medical professional liability reporting unit’s agency relationships, carried as a definite-lived intangible, was determined by using a discounted cash flow valuation. The carrying value exceeded the fair value, resulting in a $0.8 million non-cash impairment charge. A fair value for the medical professional liability reporting unit’s goodwill was determined by using a weighted average of a market approach and discounted cash flow valuation. The carrying value exceeded the fair value, resulting in a $3.6 million non-cash

impairment charge. Subsequent to the first quarter 2018 impairment, the medical professional liability reporting unit had no remaining goodwill or intangible assets. All impairment charges were recorded as net realized losses in the consolidated statement of earnings.

F. EARNINGS PER SHARE

Basic earnings per share (EPS) excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock or common stock equivalents were exercised or converted into common stock. When inclusion of common stock equivalents increases the earnings per share or reduces the loss per share, the effect on earnings is anti-dilutive. Under these circumstances, the diluted net earnings or net loss per share is computed excluding the common stock equivalents. The following represents a reconciliation of the numerator and denominator of the basic and diluted EPS computations contained in the unaudited condensed consolidated interim financial statements:

G. COMPREHENSIVE EARNINGS

Our comprehensive earnings include net earnings plus after-tax unrealized gains and losses on our fixed income portfolio. In reporting other comprehensive earnings on a net basis in the statement of earnings, we used the federal statutory tax rate of 21 percent.

Unrealized gains, net of tax, on the fixed income portfolio for the first six months of 2019 were $57.2 million, compared to $34.1 million of unrealized losses, net of tax, during the same period last year. Unrealized gains in the first six months of 2019 were attributable to declining interest rates, which increased the fair value of securities held in the fixed income portfolio. In contrast, rising interest rates decreased the fair value of securities held in the fixed income portfolio in the first six months of 2018.

The following table illustrates the changes in the balance of each component of accumulated other comprehensive earnings for each period presented in the unaudited condensed consolidated interim financial statements:

Ending balance	$	42,593	$	(14,648)	$	42,593	$	(14,648)

In 2018, the adoption of accounting standards resulted in adjustments to accumulated other comprehensive earnings. ASU 2016-01 required equity investments to be measured at fair value with changes in fair value recognized in net earnings. A cumulative-effect adjustment was made as of the beginning of 2018, which moved $142.2 million of net unrealized gains and losses on equity securities from accumulated other comprehensive earnings to retained earnings.

ASU 2018-02 addressed issues arising from the enactment of the Tax Cuts and Jobs Act of 2017. Accounting guidance required deferred tax items to be revalued based on the new tax laws with the changes included in net earnings. Since other comprehensive earnings was not affected by the revaluation of the deferred tax items, the accumulated other comprehensive earnings balance was reflective of the historic tax rate instead of the newly enacted rate, which created a stranded tax effect. ASU 2018-02 allowed for the reclassification of our $3.7 million stranded tax effect out of accumulated other comprehensive earnings into retained earnings.

The sale or other-than-temporary impairment of an available-for-sale security results in amounts being reclassified from accumulated other comprehensive earnings to current period net earnings. The effects of reclassifications out of accumulated other comprehensive earnings by the respective line items of net earnings are presented in the following table:

	$	524	$	(710)	$	1,018	$	(722)	Net earnings (loss)

2. INVESTMENTS

Our investments are primarily composed of fixed income debt securities and common stock equity securities. We carry our equity securities at fair value and categorize all of our debt securities as available-for-sale, which are carried at fair value. When available, we obtain quoted market prices to determine fair value for our investments. If a quoted market price is not available, fair value is estimated using a secondary pricing source or using quoted market prices of similar securities. We have no investment securities for which fair value is determined using Level 3 inputs as defined in note 3 to the unaudited condensed consolidated interim financial statements, “Fair Value Measurements.”

Unrealized Losses on Fixed Income Securities

We conduct and document periodic reviews of all fixed income securities with unrealized losses to evaluate whether the impairment is other-than-temporary. The following tables are used as part of our impairment analysis and illustrate the total value of fixed income securities that were in an unrealized loss position as of June 30, 2019 and December 31, 2018. The tables segregate the securities based on type, noting the fair value, amortized cost and unrealized loss on each category of investment as well as in total. The tables further classify the securities based on the length of time they have been in an unrealized loss position. As of June 30, 2019, unrealized losses on fixed income securities, as shown in the following tables, were 0.2 percent of total invested assets. Unrealized losses decreased through the first six months of 2019, as interest rates decreased from the end of 2018, increasing the fair value of securities held in the fixed income portfolio.

Evaluating Fixed Income Securities for OTTI

The fixed income portfolio contained 279 securities in an unrealized loss position as of June 30, 2019. The $3.6 million in associated unrealized losses represents 0.2 percent of the fixed income portfolio’s cost basis. Of these 279 securities, 122 have been in an unrealized loss position for 12 consecutive months or longer. All fixed income securities in the investment portfolio continue to pay the expected coupon payments under the contractual terms of the securities. Any credit-related impairment on fixed income securities we do not plan to sell and for which we are not more likely than not to be required to sell is recognized in net earnings, with the non-credit related impairment recognized in comprehensive earnings. Based on our analysis, our fixed income portfolio is of high credit quality and we believe we will recover the amortized cost basis of our fixed income securities. We continually monitor the credit quality of our fixed income investments to assess if it is probable that we will receive our contractual or estimated cash flows in the form of principal and interest. We did not recognize any other-than-temporary impairment (OTTI) losses in earnings on the fixed income portfolio in the first six months of 2019. Comparatively, we recognized $0.1 million in OTTI losses in earnings on one fixed income security that we no longer had the intent to hold in the same period in 2018. There were no OTTI losses recognized in other comprehensive earnings on the fixed income portfolio for the periods presented.

Unrealized Gains and Losses on Equity Securities

Unrealized gains recognized on equity securities still held as of June 30, 2019 were $12.9 million during the second quarter and $54.8 million during the first half of 2019. Comparatively, unrealized gains recognized on equity securities still held as of June 30, 2018 were $9.1 million during the second quarter, while unrealized losses were $4.8 million during the first half of 2018.

Other Invested Assets

We had $55.2 million of other invested assets at June 30, 2019, compared to $51.5 million at the end of 2018. Other invested assets include investments in low income housing tax credit partnerships (LIHTC), membership in the Federal Home Loan Bank of Chicago (FHLBC) and investments in private funds. Our LIHTC investments are carried at amortized cost and our investment in FHLBC stock is carried at cost. Due to the nature of the LIHTC and our membership in the FHLBC, their carrying amounts approximate fair value. The private funds are carried at fair value, using each investment’s net asset value.

Our LIHTC interests had a balance of $19.4 million at June 30, 2019, compared to $20.3 million at December 31, 2018 and recognized a total tax benefit of $0.6 million during the second quarter of 2019, the same as the prior year. For the six-month periods ended June 30, 2019 and 2018, our LIHTC interests recognized a total benefit of $1.2 million and $1.1 million, respectively. Our unfunded commitment for our LIHTC investments totaled $7.1 million at June 30, 2019 and will be paid out in installments through 2035.

As of June 30, 2019, $16.3 million of investments were pledged as collateral with the FHLBC to ensure timely access to the secured lending facility that ownership of FHLBC stock provides. As of and during the six month period ending June 30, 2019, there were no outstanding borrowings with the FHLBC.

We had $12.4 million of unfunded commitments related to our investments in private funds at June 30, 2019. Additionally, our interest in these investments is generally restricted from being transferred or otherwise redeemed without prior consent by the respective entities. An IPO would allow for the transfer of interest in some situations, while the timed dissolution of the partnership would trigger redemption in others.

14

Cash and Short-term Investments

Cash consists of uninvested balances in bank accounts. We had a cash balance of $24.8 million at June 30, 2019, compared to $30.1 million at the end of 2018. As of June 30, 2019, we had $47.4 million of short-term investments that were carried at cost and approximated fair value, compared to $11.6 million at December 31, 2018.

3. FAIR VALUE MEASUREMENTS

Assets and Liabilities Recorded at Fair Value on a Recurring Basis

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. We determined the fair value of certain financial instruments based on their underlying characteristics and relevant transactions in the marketplace. We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The following are the levels of the fair value hierarchy and a brief description of the type of valuation inputs that are used to establish each level. Financial assets are classified based upon the lowest level of significant input that is used to determine fair value.

Pricing Level 1 is applied to valuations based on readily available, unadjusted quoted prices in active markets for identical assets.

Pricing Level 2 is applied to valuations based upon quoted prices for similar assets in active markets, quoted prices for identical or similar assets in inactive markets; or valuations based on models where the significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities) or can be corroborated by observable market data.

Pricing Level 3 is applied to valuations that are derived from techniques in which one or more of the significant inputs are unobservable.

As a part of management’s process to determine fair value, we utilize widely recognized, third-party pricing sources to determine our fair values. We have obtained an understanding of the third-party pricing sources’ valuation methodologies and inputs. The following is a description of the valuation techniques used for financial assets that are measured at fair value, including the general classification of such assets pursuant to the fair value hierarchy.

Corporate, Agencies, Government and Municipal Bonds: The pricing vendor employs a multi-dimensional model which uses standard inputs including (listed in approximate order of priority for use) benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, market bids/offers and other reference data. The pricing vendor also monitors market indicators, as well as industry and economic events. All bonds valued using these techniques are classified as Level 2. All corporate, agency, government and municipal securities were deemed Level 2.

Mortgage-backed Securities (MBS)/Commercial Mortgage-backed Securities (CMBS) and Asset-backed Securities (ABS): The pricing vendor evaluation methodology includes principally interest rate movements and new issue data. Evaluation of the tranches (non-volatile, volatile or credit sensitivity) is based on the pricing vendors’ interpretation of accepted modeling and pricing conventions. This information is then used to determine the cash flows for each tranche, benchmark yields, prepayment assumptions and to incorporate collateral performance. To evaluate MBS and CMBS volatility, an option adjusted spread model is used in combination with models that simulate interest rate paths to determine market price information. This process allows the pricing vendor to obtain evaluations of a broad universe of securities in a way that reflects changes in yield curve, index rates, implied volatility, mortgage rates and recent trade activity. MBS/CMBS and ABS with corroborated, observable inputs are classified as Level 2. All of our MBS/CMO and ABS are deemed Level 2.

For all of our fixed income securities classified as Level 2, as described above, we periodically conduct a review to assess the reasonableness of the fair values provided by our pricing services. Our review consists of a two-pronged approach. First, we compare prices provided by our pricing services to those provided by an additional source. In some cases, we obtain prices from securities brokers and compare them to the prices provided by our pricing services. In both comparisons, if discrepancies are found, we compare our prices to actual reported trade data for like securities. No changes to the fair values supplied by our pricing services have occurred as a result of our reviews. Based on these assessments, we have determined that the fair values of our Level 2 securities provided by our pricing services are reasonable.

15

Common Stock: All but one of our common stock holdings are traded on an exchange. Exchange traded equities have readily observable price levels and are classified as Level 1 (fair value based on quoted market prices). Pricing for the equity security not traded on an exchange is provided by a third-party pricing source and is classified as Level 2.

Due to the relatively short-term nature of cash, short-term investments, accounts receivable and accounts payable, their carrying amounts are reasonable estimates of fair value. Our investments in private funds, classified as other invested assets, are measured using the investment’s net asset value per share and are not categorized within the fair value hierarchy.

Assets measured at fair value in the accompanying unaudited condensed consolidated interim financial statements on a recurring basis are summarized below:

4. HISTORICAL LOSS AND LAE DEVELOPMENT

The following table is a reconciliation of our unpaid losses and settlement expenses (LAE) for the first six months of 2019 and 2018:

	For the Six-Month Periods

Ceded		(362,310)		(315,117)
Net	$	1,143,969	$	1,028,131

For the first six months of 2019, incurred losses and LAE included $40.8 million of favorable development on prior years’ loss reserves. The majority of products experienced modest amounts of favorable development on prior accident years, with notable contributions from transportation, general liability, commercial excess and personal umbrella, professional services and surety. Executive products was the exception and experienced adverse development.

For the first six months of 2018, incurred losses and LAE included $28.0 million of favorable development on prior years’ loss reserves. Commercial excess and personal umbrella, general liability, marine and surety were drivers of the favorable development. Executive products, transportation and medical professional liability experienced adverse development.

5. INCOME TAXES

Our effective tax rate for the three and six-month periods ended June 30, 2019 was 17.1 percent and 18.9 percent, respectively, compared to 16.0 percent and 15.7 percent, respectively, for the same periods in 2018. Effective rates are dependent upon components of pretax earnings and the related tax effects. The effective rate was higher for the first six months of 2019 due largely to higher levels of pre-tax earnings, which caused the tax-favored adjustments to be smaller on a percentage basis in 2019 compared to the prior year.

Income tax expense attributable to income from operations for the three and six-month periods ended June 30, 2019 and 2018 differed from the amounts computed by applying the U.S. federal tax rate of 21 percent to pretax income by the items detailed in the below table. In interim periods, income taxes are adjusted to reflect the effective tax rate we anticipate for the year, with adjustments flowing through the other items line.

6. STOCK BASED COMPENSATION

Our RLI Corp. Long-Term Incentive Plan (2010 LTIP) was in place from 2010 to 2015. The 2010 LTIP provided for equity-based compensation, including stock options, up to a maximum of 4,000,000 shares of common stock (subject to adjustment for changes in our capitalization and other events). Between 2010 and 2015, we granted 2,878,000 stock options under the 2010 LTIP. The 2010 LTIP was replaced in 2015.

In 2015, our shareholders approved the 2015 RLI Corp. Long-Term Incentive Plan (2015 LTIP), which provides for equity-based compensation and replaced the 2010 LTIP. In conjunction with the adoption of the 2015 LTIP, effective May 7, 2015, options were no longer granted under the 2010 LTIP. Awards under the 2015 LTIP may be in the form of restricted stock, restricted stock units, stock options (non-qualified only), stock appreciation rights, performance units as well as other stock-based awards. Eligibility under the 2015 LTIP is limited to employees and directors of the Company or any affiliate. The granting of awards under the 2015 LTIP is solely at the discretion of the board of directors. The maximum number of shares of common stock available for distribution under the 2015 LTIP is 4,000,000 shares (subject to adjustment for changes in our capitalization and other events). Since the plan’s approval in 2015, we have granted 2,217,710 awards under the 2015 LTIP, including 314,080 thus far in 2019.

Stock Options

Under the 2015 LTIP, as under the 2010 LTIP, we grant stock options for shares with an exercise price equal to the fair market value of the shares at the date of grant (subject to adjustments for changes in our capitalization, special dividends and other events as set forth in such plans). Options generally vest and become exercisable ratably over a five-year period and expire eight years after grant.

For most participants, the requisite service period and vesting period will be the same. For participants who are retirement eligible, defined by the plan as those individuals whose age and years of service equals 75, the requisite service period is deemed to be met and options are immediately expensed on the date of grant. For participants who will become retirement eligible during the vesting period, the requisite service period over which expense is recognized is the period between the grant date and the attainment of retirement eligibility. Shares issued upon option exercise are newly issued shares.

Exercisable options at June 30, 2018	996,265	$	44.04	3.89	$	22,089

The majority of our stock options are granted annually at our regular board meeting in May. In addition, options are approved at the May meeting for quarterly grants to certain retirement eligible employees. Since stock option grants to retirement eligible employees are fully expensed when issued, the approach allows for a more even expense distribution throughout the year.

Thus far in 2019, 292,150 stock options were granted with a weighted average exercise price of $80.36 and a weighted average fair value of $13.33. We recognized $1.4 million of expense in the second quarter of 2019 and $2.4 million in the first six months of 2019 related to options vesting. Since options granted under our 2015 LTIP are non-qualified, we recorded a tax benefit of $0.3 million in the second quarter of 2019 and $0.5 million in the first six months of 2019 related to this compensation expense. Total unrecognized compensation expense relating to outstanding and unvested options was $6.7 million, which will be recognized over the remainder of the vesting period. Comparatively, we recognized $1.3 million of compensation expense in the second quarter of 2018 and $2.3 million in the first six months of 2018. We recorded a tax benefit of $0.3 million in the second quarter of 2018 and $0.5 million in the first six months of 2018 related to this compensation expense.

The fair value of options was estimated using a Black-Scholes based option pricing model with the following weighted average grant-date assumptions and weighted average fair values as of June 30:

	2019			2018
Weighted-average fair value of grants	$	13.33		$	10.20
Risk-free interest rates		2.42	%		2.69	%
Dividend yield		2.69	%		3.15	%
Expected volatility		22.71	%		22.88	%
Expected option life		4.96	years		5.06	years

The risk-free rate was determined based on U.S. treasury yields that most closely approximated the option’s expected life. The dividend yield was determined based on the average annualized quarterly dividends paid during the most recent five-year period and incorporated a consideration for special dividends paid in recent history. The expected volatility was calculated based on the median of the rolling volatilities for the expected life of the options. The expected option life was determined based on historical exercise behavior and the assumption that all outstanding options will be exercised at the midpoint of the current date and remaining contractual term, adjusted for the demographics of the current year’s grant.

19

Restricted Stock Units

In addition to stock options, restricted stock units (RSUs) are granted with a value equal to the closing stock price of the Company’s stock on the dates the units are granted. Generally, these units have a three-year cliff vesting. When participants terminate employment with the Company after having met the definition of retirement under the 2015 LTIP, defined as those individuals whose age and years of service equals 75, the RSUs will become fully vested. In addition, the RSUs have dividend participation, which accrue as additional units and are settled with granted stock units at the end of the vesting period.

As of June 30, 2019, 45,350 RSUs have been granted to employees under the 2015 LTIP, including 15,275 in 2019, and 44,431 remain outstanding. We recognized $0.2 million of expense on these units in the second quarter of 2019 and $0.3 million in the first six months of 2019. Total unrecognized compensation expense relating to outstanding and unvested RSUs was $1.5 million, which will be recognized over the remainder of the vesting period. Comparatively, we recognized $0.1 million of expense in the second quarter of 2018 and $0.2 million in the first six months of 2018.

In 2018 and 2019, each outside director received RSUs with a fair market value of $50,000 on the date of grant as part of annual director compensation. Director RSUs vest one year from the date of grant. As of June 30, 2019, 15,085 restricted stock units have been granted to directors under the 2015 LTIP, including 6,655 in 2019, and 7,402 remain outstanding. We recognized $0.2 million of compensation expense on these units in the second quarter of 2019 and $0.3 million in the first six months of 2019. Total unrecognized compensation expense relating to outstanding and unvested director RSUs was $0.4 million, which will be recognized over the remainder of the vesting period. Comparatively, we recognized $0.1 million of compensation expense for the three and six-month periods ended June 30, 2018.

8. LEASES

We adopted ASU 2016-02, Leases on January 1, 2019, which resulted in the recognition of operating leases on the balance sheet in 2019 and forward. See note 1c for more information on the adoption of the ASU. Right-of-use assets are included in the other assets line item and lease liabilities are included in the other liabilities line item of the consolidated balance sheet. We determine if a contract contains a lease at inception and recognize operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments at the commencement date. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. Lease agreements may include options to extend or terminate. The options are exercised at our discretion and are included in operating lease liabilities if it is reasonably certain the option will be exercised. Lease agreements have lease and non-lease components, which are accounted for as a single lease component. Lease expense is recognized on a straight-line basis over the lease term.

The Company’s operating lease obligations are for branch office facilities. Our leases have remaining lease terms of 1 to 16 years. Expenses associated with leases totaled $6.9 million in 2018, $6.8 million in 2017 and $6.4 million in 2016. The components of lease expense and other lease information as of and during the three and six-month period ended June 30, 2019 are as follows:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

“SAFE HARBOR” STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995: This discussion and analysis may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 that are not historical facts, and involve risks and uncertainties that could cause actual results to differ materially from those expected and projected. Various risk factors that could affect future results are listed in our filings with the Securities and Exchange Commission, including the Annual Report on Form 10-K for the year ended December 31, 2018.

OVERVIEW

RLI Corp. (the Company) was founded in 1965. We underwrite specialty property and casualty insurance through major subsidiaries collectively known as RLI Insurance Group (the Group). We conduct operations principally through three insurance companies. RLI Insurance Company (RLI Ins.), a subsidiary of RLI Corp. and our principal insurance subsidiary, writes multiple lines of insurance on an admitted basis in all 50 states, the District of Columbia, Puerto Rico, the Virgin Islands and Guam. Mt. Hawley Insurance Company (Mt. Hawley), a subsidiary of RLI Ins., writes excess and surplus lines insurance on a non-admitted basis in all 50 states, the District of Columbia, Puerto Rico, the Virgin Islands and Guam. Contractors Bonding and Insurance Company (CBIC), a subsidiary of RLI Ins., writes multiple lines of insurance on an admitted basis in all 50 states and the District of Columbia. Each of our insurance companies is domiciled in Illinois.

22

As a specialty insurance company with a niche focus, we offer insurance coverages in the specialty admitted and excess and surplus markets. Coverages in the specialty admitted market such as our energy surety bonds, are for risks that are unique or hard-to-place in the standard market, but must remain with an admitted insurance company for regulatory or marketing reasons. In addition, our coverages in the specialty admitted market may be designed to meet specific insurance needs of targeted insured groups, such as our professional liability and package coverages for design professionals and our stand-alone personal umbrella policy. The specialty admitted market is subject to more state regulation than the excess and surplus market, particularly with regard to rate and form filing requirements, restrictions on the ability to exit lines of business, premium tax payments and membership in various state associations, such as state guaranty funds and assigned risk plans. We also underwrite coverages in the excess and surplus market. The excess and surplus market, unlike the admitted market, is less regulated and more flexible in terms of policy forms and premium rates. This market provides an alternative for customers with risks or loss exposures that generally cannot be written in the standard market. This typically results in coverages that are more restrictive and more expensive than coverages in the admitted market. When we underwrite within the excess and surplus market, we are selective in the lines of business and type of risks we choose to write. Using our non-admitted status in this market allows us to tailor terms and conditions to manage these exposures effectively. Often, the development of these coverages is generated through proposals brought to us by an agent or broker seeking coverage for a specific group of clients or loss exposures. Once a proposal is submitted, our underwriters determine whether it would be a viable product based on our business objectives.

The foundation of our overall business strategy is to underwrite for profit in all market conditions and we have achieved this for 23 consecutive years, averaging an 88.1 combined ratio over that period of time. This drives our ability to provide shareholder returns in three different ways: the underwriting income itself, net investment income from our investment portfolio and long-term appreciation in our equity portfolio. Our investment strategy is based on preservation of capital as the first priority, with a secondary focus on generating total return. The fixed income portfolio consists primarily of highly-rated, diversified, liquid, investment-grade securities. Consistent underwriting income allows a portion of our investment portfolio to be invested in equity securities and other risk asset classes. Our equity portfolio consists of a core stock portfolio weighted toward dividend-paying stocks, as well as exchange traded funds (ETFs). Our minority equity ownership interests in Maui Jim, Inc. (Maui Jim), a manufacturer of high-quality sunglasses, and Prime Holdings Insurance Services, Inc. (Prime), a specialty insurance company, have also enhanced financial results. We have a diversified investment portfolio and closely monitor our investment risks. Despite periodic fluctuations in market value, our equity portfolio is part of a long-term asset allocation strategy and has contributed significantly to our historic growth in book value.

We measure the results of our insurance operations by monitoring growth and profitability across three distinct business segments: casualty, property and surety. Growth is measured in terms of gross premiums written and profitability is analyzed through combined ratios, which are further subdivided into their respective loss and expense components.

The property and casualty insurance business is cyclical and influenced by many factors, including price competition, economic conditions, natural or man-made disasters (for example, earthquakes, hurricanes and terrorism), interest rates, state regulations, court decisions and changes in the law.

One of the unique and challenging features of the property and casualty insurance business is that coverages must be priced before costs have fully developed, because premiums are charged before claims are incurred. This requires that liabilities be estimated and recorded in recognition of future loss and settlement obligations. Due to the inherent uncertainty in estimating these liabilities, there can be no assurance that actual liabilities will not be more or less than recorded amounts; if actual liabilities differ from recorded amounts, there will be an adverse or favorable effect on net earnings. In evaluating the objective performance measures previously mentioned, it is important to consider the following individual characteristics of each major insurance segment.

The casualty portion of our business consists largely of commercial excess, personal umbrella, general liability, transportation and executive products coverages, as well as package business and other specialty coverages, such as professional liability and workers’ compensation for office-based professionals. We also offer fidelity and crime coverage for commercial insureds and select financial institutions. We exited the medical professional liability business in 2019 as losses had exceeded our expectations and our assessment of the competitive environment did not support a conclusion that an underwriting profit could be achieved in the near term. The casualty business is subject to the risk of estimating losses and related loss reserves because the ultimate settlement of a casualty claim may take several years to fully develop. The casualty segment is also subject to inflation risk and may be affected by evolving legislation and court decisions that define the extent of coverage and the amount of compensation due for injuries or losses.

23

Our property segment is comprised primarily of commercial fire, earthquake, difference in conditions and marine coverages. We also offer select personal lines policies, including homeowners’ coverages. Property insurance results are subject to the variability introduced by perils such as earthquakes, fires and hurricanes. Our major catastrophe exposure is to losses caused by earthquakes, primarily on the West Coast. Our second largest catastrophe exposure is to losses caused by wind storms to commercial properties throughout the Gulf and East Coast, as well as to homes we insure in Hawaii. We limit our net aggregate exposure to a catastrophic event by minimizing the total policy limits written in a particular region, purchasing reinsurance and maintaining policy terms and conditions throughout market cycles. We also use computer-assisted modeling techniques to provide estimates that help us carefully manage the concentration of risks exposed to catastrophic events.

The surety segment specializes in writing small to large-sized commercial and contract surety coverages, as well as those for the energy, petrochemical and refining industries. We also offer miscellaneous bonds including license and permit, notary and court bonds. Often, our surety coverages involve a statutory requirement for bonds. While these bonds typically maintain a relatively low loss ratio, losses may fluctuate due to adverse economic conditions affecting the financial viability of our principals. The contract surety product guarantees the construction work of a commercial contractor for a specific project. Generally, losses occur due to the deterioration of a contractor’s financial condition. This line has historically produced marginally higher loss ratios than other surety lines during economic downturns.

The insurance marketplace is intensely competitive across all of our segments. Despite challenges that exist in today’s marketplace, we believe that our business model is built to create underwriting income by focusing on sound risk selection and discipline. Our primary focus will continue to be on underwriting profitability, with a secondary focus on premium growth where we believe underwriting profit exists, as opposed to general premium growth or market share measurements.

GAAP, non-GAAP and Performance Measures

Throughout this quarterly report, we include certain non-generally accepted accounting principles (non-GAAP) financial measures. Management believes that these non-GAAP measures better explain the Company’s results of operations and allow for a more complete understanding of the underlying trends in the Company’s business. These measures should not be viewed as a substitute for those determined in accordance with generally accepted accounting principles in the United States of America (GAAP). In addition, our definitions of these items may not be comparable to the definitions used by other companies.

Following is a list of non-GAAP measures found throughout this report with their definitions, relationships to GAAP measures and explanations of their importance to our operations.

Underwriting Income

Underwriting income or profit represents one measure of the pretax profitability of our insurance operations and is derived by subtracting losses and settlement expenses, policy acquisition costs and insurance operating expenses from net premiums earned, which are all GAAP financial measures. Each of these captions is presented in the statements of earnings but is not subtotaled. However, this information is available in total and by segment on page 20 of this quarterly report on Form 10-Q and in note 11 to the consolidated financial statements in our 2018 Annual Report on Form 10-K, regarding operating segment information. The nearest comparable GAAP measure is earnings before income taxes which, in addition to underwriting income, includes net investment income, net realized gains or losses, net unrealized gain or losses on equity securities, general corporate expenses, debt costs and our portion of earnings from unconsolidated investees.

Combined Ratio

The combined ratio, which is derived from components of underwriting income, is a common industry performance measure of profitability for underwriting operations and is calculated in two components. First, the loss ratio is losses and settlement expenses divided by net premiums earned. The second component, the expense ratio, reflects the sum of policy acquisition costs and insurance operating expenses divided by net premiums earned. All items included in these components of the combined ratio are presented in our GAAP consolidated financial statements. The sum of the loss and expense ratios is the combined ratio. The difference between the combined ratio and 100 reflects the per-dollar rate of underwriting income or loss.

24

Net Unpaid Loss and Settlement Expenses

Unpaid losses and settlement expenses, as shown in the liabilities section of our balance sheets, represents the total obligations to claimants for both estimates of known claims and estimates for incurred but not reported (IBNR) claims. The related asset item, reinsurance balances recoverable on unpaid losses and settlement expense, is the estimate of known claims and estimates of IBNR that we expect to recover from reinsurers. The net of these two items is generally referred to as net unpaid loss and settlement expenses and is commonly used in our disclosures regarding the process of establishing these various estimated amounts.

Critical Accounting Policies

In preparing the unaudited condensed consolidated interim financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates.

The most critical accounting policies involve significant estimates and include those used in determining the liability for unpaid losses and settlement expenses, investment valuation and OTTI, recoverability of reinsurance balances, deferred policy acquisition costs and deferred taxes. For a detailed discussion of each of these policies, refer to our 2018 Annual Report on Form 10-K. There have been no significant changes to any of these policies during the current year.

RESULTS OF OPERATIONS

Six Months Ended June 30, 2019 Compared to Six Months Ended June 30, 2018

Consolidated revenue for the first half of 2019 increased $96.7 million, or 24 percent, from the same period in 2018. Net premiums earned for the Group increased 7 percent, driven by growth from our casualty and property segments. Investment income increased 17 percent due to an increased asset base and higher average yields relative to the prior year. Realized gains during the first half of 2019 were $13.8 million and were comprised of $12.3 million of realized gains on equity securities from normal rebalancing, $1.3 million of realized gains on the fixed income portfolio and $0.2 million of miscellaneous realized gains. This compares to realized gains of $34.5 million on the equity portfolio that were partially offset by $0.9 million of realized losses in the fixed income portfolio and a $4.4 million non-cash impairment charge on goodwill and definite-lived intangibles for the same period in 2018. Additionally, $42.3 million of net unrealized gains on equity securities were recognized in the first half of 2019 compared to $39.4 million of net unrealized losses in the same period in 2018.

	2019		2018
Consolidated revenues (in thousands)
Net premiums earned	$	412,230	$	386,549

Net realized gains		13,832		29,253
Net unrealized gains (losses) on equity securities		42,308		(39,383)
Total consolidated revenue	$	501,933	$	405,228

Net after-tax earnings for the first half of 2019 totaled $105.9 million, compared to $45.5 million for the same period last year. The increase in earnings for 2019 was influenced by $33.4 million of after-tax unrealized gains on equity securities compared to $31.1 million of after-tax unrealized losses on equity securities in 2018. Underwriting results for both periods reflect profitable current accident year results and favorable development from prior years’ loss reserves. Favorable development on prior years’ loss reserves provided additional pretax earnings of $40.8 million in the first half of 2019 and $28.0 million in 2018. Pretax storm losses were $5.0 million in the first six months of 2019, compared to $10.0 million of total catastrophe losses for the same period in 2018, which were largely the result of volcanic activity in Hawaii. Pretax bonus and profit sharing-related expenses associated with the net impact of prior years’ reserve development and catastrophe losses totaled $5.3 million in 2019, compared to $2.9 million in 2018. These performance-related expenses affected policy acquisition, insurance operating and general corporate expenses. Bonus and profit-sharing amounts earned by executives, managers and associates are predominately influenced by corporate performance including operating earnings, combined ratio and return on capital. These performance-related expenses were further increased in the first half of 2019 based on the overall growth in earnings and book value.

25

During the first half of 2019, equity in earnings of unconsolidated investees totaled $13.8 million. This amount includes $10.1 million from Maui Jim and $3.7 million from Prime. Comparatively, the first half of 2018 reflected $12.3 million of earnings, including $10.8 million from Maui Jim and $1.5 million from Prime.

Comprehensive earnings totaled $163.1 million for the first six months of 2019, compared to $11.4 million for the same period in 2018. Other comprehensive earnings primarily included after-tax unrealized gains and losses from the fixed income portfolio. In 2019, declining interest rates resulted in unrealized gains on the fixed income portfolio and $57.2 million of other comprehensive earnings in the first six months. This compares to $34.1 million of other comprehensive loss for the same period in 2018, primarily attributable to increasing interest rates during the period.

RLI Insurance Group

Gross premiums written for the Group increased $27.5 million, or 6 percent, for the first half of 2019 when compared to 2018. Products in our casualty and property segments drove the growth. Net premiums earned increased $25.7 million, or 7 percent, also driven by products in our casualty and property segments.

Casualty

Gross premiums written for the casualty segment in the first six months of 2019 were up 7 percent, or $22.3 million. Premiums from commercial excess and personal umbrella increased $13.9 million, due in part to an expanded distribution base in personal umbrella and larger scale in the energy casualty space. Our executive products group grew $8.1 million as rate increases were achieved, market turmoil created new business opportunities and our newer cyber liability and representations and warranties products expanded. General liability, transportation, professional services and small commercial also contributed to the growth during the first half of the year. As previously announced, we reduced our quota share reinsurance agreement with Prime from 25 percent to 6 percent at the beginning of 2019 and exited from our medical professional liability

26

lines due to unfavorable market conditions and poor underwriting performance. The actions on these programs account for the decline in other casualty and offset continued growth in our general binding authority and mortgage reinsurance lines.

Property

Gross premiums written for the Group’s property segment totaled $113.4 million for the first half of 2019, up 9 percent from the same period last year. Market disruption has provided opportunity for our marine product and, along with rate increases, led to a 28 percent increase in premiums written over the first half of 2018. Hawaii homeowners, within the specialty personal group, benefited from continued investment in relationships and distribution with growth of 15 percent. Commercial property is down 5 percent, despite rate increases in the wind market, as we continued to manage exposures. Rates for non-wind coverages remain flat to down.

Surety

The surety segment recorded gross premiums written of $59.6 million for the first six months of 2019, a decrease of $4.0 million from the same period last year. Competitive market conditions led to a reduction in miscellaneous, energy and contract surety production, which was partially offset by growth within our commercial lines. Selectively reducing exposures on high risk accounts, given the current stage in the credit cycle, and restructuring one program in the miscellaneous surety book also resulted in a decline in premium for the first half of the year.

RLI Insurance Group

Underwriting income for the Group totaled $37.4 million for the first half of 2019, compared to $31.6 million in the same period last year. Both periods reflect positive underwriting results for the current accident year and favorable reserve development on prior accident years, with 2019 experiencing a larger benefit. The combined ratio for the Group totaled 90.9 in 2019, compared to 91.8 in 2018. The loss ratio decreased to 48.1 from 50.2, due to the increased level of favorable development in 2019. The Group’s expense ratio increased to 42.8 from 41.6 as strong growth in earnings and book value led to increased bonus and profit-sharing expenses.

Casualty

The casualty segment recorded underwriting income of $12.3 million in the first half of 2019, compared to $4.4 million for the same period last year. Reserve releases reduced loss and settlement expenses for the casualty segment by $30.7 million, primarily on accident years 2015 through 2018. General liability, professional services, transportation, commercial excess and personal umbrella and small commercial all contributed to the favorable development, while executive products experienced adverse development. In comparison, $14.5 million of reserves were released in the first half of 2018, largely driven by commercial excess, personal umbrella and general liability. A majority of the difference between the reserve releases in 2019 and 2018 can be attributed to the contrast between the favorable development in 2019 and adverse development in 2018 within our transportation business.

The combined ratio for the casualty segment was 95.5 in 2019, compared to 98.3 in 2018. The segment’s loss ratio was 58.3 in 2019, down from 62.8 in 2018. The loss ratio decreased in 2019 as a result of more favorable development on prior

27

years’ reserves. The expense ratio for the casualty segment was 37.2, up from 35.5 for the same period last year, due to investments in technology and a larger amount of bonus and profit-sharing expenses.

Property

The property segment recorded underwriting income of $7.8 million for the first half of 2019, compared to $9.5 million for the same period last year. Loss and settlement expenses for 2019 included $2.1 million of favorable development on prior years’ loss and catastrophe reserves and $4.7 million of storm losses. Comparatively, the 2018 underwriting results included $6.5 million of favorable development on prior years’ loss and catastrophe reserves, primarily from the marine business, $6.5 million of losses from the volcanic activity in Hawaii and $3.2 million of storm losses.

The combined ratio for the casualty segment was 90.1, compared to 86.8 for the same period last year. The segment’s loss ratio was 45.1 in 2019, up from 41.8 in 2018 due to a combination of a higher current accident year loss ratio and lower levels of reserve releases than in the prior year. The segment’s expense ratio was 45.0 in 2019 and 2018, as a higher premium base offset increased expenses.

Surety

The surety segment recorded underwriting income of $17.3 million for the first half of 2019, compared to $17.7 million for the same period last year. Both periods reflected positive current accident year underwriting performance and benefited from favorable development on prior years’ loss reserves. Results for 2019 included favorable development on prior accident years’ reserves across most surety lines, which decreased loss and settlement expenses for the segment by $8.0 million. Comparatively, 2018 results included favorable development on prior accident years’ loss reserves across all products, which decreased the segment’s loss and settlement expenses by $7.0 million.

The combined ratio for the surety segment totaled 70.4 for the first half of 2019, compared to 69.8 for the same period in 2018. The segment’s loss ratio was 3.6 for 2019, compared to 5.8 for 2018. The loss ratio decrease was the result of a lower current accident year loss ratio and a higher amount of favorable development on prior accident year reserves. The expense ratio was 66.8, up from 64.0 in the prior year, due to increased investments in technology and higher bonus and profit-sharing expenses on a slightly lower premium base.

Investment Income and Realized Capital Gains

Our investment portfolio generated net investment income of $33.6 million during the first half of 2019, an increase of 16.5 percent from that reported for the same period in 2018. The increase in investment income was due to an increased asset base and higher average yields relative to the prior year.

Yields on our fixed income investments for the first half of 2019 and 2018 were as follows:

	2019		2018
Pretax Yield
Taxable	3.44	%	3.22	%
Tax-Exempt	2.83	%	2.68	%
After-Tax Yield
Taxable	2.72	%	2.54	%
Tax-Exempt	2.68	%	2.54	%

We recognized $13.8 million of realized gains in the first six months of 2019, which were comprised of $12.3 million of realized gains on equity securities, $1.3 million of realized gains on the fixed income portfolio and $0.2 million of miscellaneous realized gains. This compares to realized gains of $34.5 million on equity securities from rebalancing the portfolio that were partially offset by $0.9 million of realized losses in the fixed income portfolio as well as realized losses related to a non-cash impairment charge on goodwill and definite-lived intangibles for the same period in 2018.

The following table depicts the composition of our investment portfolio at June 30, 2019 as compared to December 31, 2018:

	June 30, 2019				December 31, 2018
	Financial				Financial
(in thousands)	Stmt Value		%		Stmt Value		%
Fixed income	$	1,865,613	77.2	%	$	1,760,515	80.2	%
Equity securities		421,801	17.5	%		340,483	15.5	%
Other invested assets		55,196	2.3	%		51,542	2.4	%
Cash and short-term investments		72,187	3.0	%		41,690	1.9	%
Total	$	2,414,797	100.0	%	$	2,194,230	100.0	%

We believe our overall asset allocation best meets our strategy to preserve capital for policyholders, provide sufficient income to support insurance operations, and to effectively grow book value over a long-term investment horizon.

The fixed income portfolio increased by $105.1 million in the first six months of 2019. The increase was due to cash flows being allocated to the fixed income portfolio as well as the decline in interest rates during the first half of the year, increasing the fair value of securities in the fixed income portfolio. Average fixed income duration was 4.8 years at June 30, 2019, reflecting our current liability structure and sound capital position. The equity portfolio increased by $81.3 million during the first six months of 2019 due largely to strong equity market returns.

Income Taxes

Our effective tax rate for the first half of 2019 was 18.9 percent, compared to 15.7 percent for the same period in 2018. Effective rates are dependent upon components of pretax earnings and the related tax effects. The effective rate was higher for the first half of 2019 due to higher levels of pre-tax earnings, which caused the tax-favored adjustments to be smaller on a percentage basis in 2019 compared to the prior year.

Three Months Ended June 30, 2019 Compared to Three Months Ended June 30, 2018

Consolidated revenue for the second quarter of 2019 increased $18.8 million, or 9 percent, from the same period in 2018. Net premiums earned for the Group increased 6 percent, driven by growth from our casualty and property segments. Investment income increased 17 percent due to an increased asset base and higher average yields relative to the prior year. Realized gains during the quarter were $4.8 million and were comprised of $3.9 million of realized gains on equity securities, $0.7 million of realized gains on the fixed income portfolio and $0.2 million of miscellaneous realized gains. This compares to $21.7 million of realized gains on the equity portfolio from normal rebalancing and $0.9 million of realized losses on the fixed income portfolio for the same period in 2018. Additionally, $8.8 million of net unrealized gains on equity securities were recognized in the second quarter of 2019 compared to $12.6 million of net unrealized losses in the same period in 2018.

Net unrealized gains (losses) on equity securities		8,810		(12,611)
Total consolidated revenue	$	238,113	$	219,337

Net after-tax earnings for the second quarter of 2019 totaled $40.5 million, compared to $33.3 million for the same period last year. The increase in earnings for 2019 was influenced by $10.7 million of net after-tax realized gains and unrealized gains on equity securities compared to $6.5 million in 2018. Underwriting results for both periods reflect profitable current accident year results and favorable development from prior years’ loss reserves. Favorable development on prior years’ loss reserves provided additional pretax earnings of $21.2 million in the second quarter of 2019 compared to $13.5 million in 2018. Catastrophe activity consisted of $4.0 million of pretax storm losses in the second quarter of 2019, compared to $1.5 million of storm losses and $6.5 million of losses from volcanic activity in Hawaii for the same period in the prior year. Pretax bonus and profit sharing-related expenses associated with the net impact of prior years’ reserve development and catastrophe losses

29

totaled $2.5 million in 2019, compared to a $1.0 million in 2018. These performance-related expenses affected policy acquisition, insurance operating and general corporate expenses. Bonus and profit-sharing amounts earned by executives, managers and associates are predominately influenced by corporate performance including operating earnings, combined ratio and return on capital. These performance-related expenses were further increased in the second quarter of 2019 based on the overall growth in earnings and book value.

During the second quarter of 2019, equity in earnings of unconsolidated investees totaled $8.5 million. This amount includes $6.5 million from Maui Jim and $2.0 million from Prime. Comparatively, the second quarter of 2018 reflected $7.1 million of earnings, including $6.6 million from Maui Jim and $0.5 million from Prime.

Comprehensive earnings totaled $68.3 million for the second quarter of 2019, compared to $25.6 million for the second quarter of 2018. Other comprehensive earnings primarily included after-tax unrealized gains and losses from the fixed income portfolio. The second quarter’s $27.9 million of other comprehensive earnings was due to unrealized gains on the fixed income portfolio as interest rates declined. This compares to $7.7 million of other comprehensive loss for the same period in 2018, primarily attributable to increasing interest rates during the period.

RLI Insurance Group

Gross premiums written for the Group increased $13.5 million, or 5 percent, for the second quarter of 2019 when compared to 2018. Products in our casualty and property segments drove the growth. Net premiums earned increased $11.0 million, or 6 percent, also driven by products in our casualty and property segments.

Casualty

Gross premiums written for the casualty segment were up 6 percent, or $10.6 million, in the second quarter of 2019. Although the repositioning we undertook at the beginning of the year reduced the impact, the segment experienced exposure growth and a 5 percent rate increase. Premiums from commercial excess and personal umbrella increased $7.2 million, due in

30

part to an expanded distribution base in personal umbrella and larger scale in the energy casualty space. General liability and our executive products group also made contributions during the quarter with both mature and newer product offerings, such as cyber liability and representation and warranties coverages, experiencing exposure growth. Other casualty, which includes assumed premiums from Prime and our medical professional liability lines, decreased $9.3 million, despite growth from our general binding authority and mortgage reinsurance business. As previously announced, we reduced our quota share reinsurance agreement with Prime from 25 percent to 6 percent at the beginning of 2019 and exited from our medical professional liability lines due to unfavorable market conditions and poor underwriting performance.

Property

Gross premiums written for the property segment totaled $64.4 million for the second quarter of 2019, up 10 percent from the same period last year. Our marine business accounted for a large portion of the increase with $24.1 million of premiums written, up 32 percent over the second quarter of 2018. Production from specialty personal reflects growth from our Hawaii homeowners’ product, which was up 14 percent. While renewal rates for catastrophe prone wind exposures continue to improve, gross written premium from our commercial property lines declined 3 percent as we continued to manage exposures.

Surety

The surety segment recorded gross premiums written of $29.8 million for the second quarter of 2019, a decrease of $3.3 million from the same period last year. Competitive market conditions led to a reduction across all surety lines. Restructuring of one program resulted in a further decline of miscellaneous surety premium in the second quarter.

RLI Insurance Group

Underwriting income for the Group totaled $14.9 million for the second quarter of 2019, compared to $14.1 million in the same period last year. Both periods reflect positive underwriting results for the current accident year and favorable reserve development on prior accident years, with 2019 experiencing a larger benefit. The combined ratio for the Group totaled 92.8 in 2019, the same as in 2018. The loss ratio decreased to 50.1 from 51.7, due to the increased level of favorable development in 2019. The Group’s expense ratio increased to 42.7 from 41.1 as strong growth in earnings and book value led to increased bonus and profit-sharing expenses.

Casualty

The casualty segment recorded underwriting income of $6.9 million in the second quarter of 2019, compared to $2.9 million for the same period last year. Reserve releases reduced loss and settlement expenses for the casualty segment by $17.5 million, primarily on accident years 2015 through 2018. Nearly every product contributed to the favorable development and no active programs had significant adverse development. In comparison, $7.4 million of reserves were released in the second quarter of 2018, largely driven by commercial excess, personal umbrella and the executive products group. A majority of the difference between the reserve releases in 2019 and 2018 can be attributed to the contrast between the favorable development in 2019 and the adverse development in 2018 within our transportation business.

The combined ratio for the casualty segment was 95.0 in 2019, compared to 97.8 in 2018. The segment’s loss ratio was 57.9 in 2019, down from 62.8 in 2018. The loss ratio decreased in 2019 as a result of more favorable development on prior

31

years’ reserves. The expense ratio for the casualty segment was 37.1, up from 35.0 for the same period last year, due to investments in technology and higher bonus and profit-sharing expenses.

Property

The property segment recorded an underwriting loss of $0.4 million for the second quarter of 2019, compared to $3.6 million of underwriting income for the same period last year. The current accident year was impacted by a few large isolated losses that increased loss and settlement expense. Underwriting results for 2019 also included $0.1 million of adverse development on prior years’ loss and catastrophe reserves and $3.9 million of storm losses. Comparatively, the 2018 underwriting results included $3.8 million of favorable development on prior years’ loss and catastrophe reserves, primarily from the marine business, $6.5 million of net losses from volcanic activity in Hawaii and $1.3 million of storm losses.

Underwriting results for the second quarter of 2019 translated into a combined ratio of 101.1, compared to 90.2 for the same period last year. The segment’s loss ratio was 56.5 in 2019, up from 46.1 in 2018 due to a combination of increased current accident year non-catastrophe losses and the impact of the difference in prior accident years’ reserve releases discussed above. The segment’s expense ratio increased to 44.6 in 2019 from 44.1 in the prior year, as strong growth in overall earnings and book value led to an increase in bonus and profit-sharing expenses.

Surety

The surety segment recorded underwriting income of $8.4 million for the second quarter of 2019, compared to $7.6 million for the same period last year. Both periods reflected positive current accident year underwriting performance and benefited from favorable development on prior years’ loss reserves. Results for 2019 included favorable development on prior accident years’ reserves across all surety lines, which decreased loss and settlement expenses for the segment by $3.8 million. Comparatively, 2018 results included favorable development on prior accident years’ loss reserves across most products, which decreased the segment’s loss and settlement expenses by $2.3 million.

The combined ratio for the surety segment totaled 71.2 for the second quarter of 2019, compared to 74.3 for the same period in 2018. The segment’s loss ratio was 4.1 in 2019, down from 10.3 in 2018. The loss ratio decrease was the result of a lower current accident year loss ratio and a higher amount of favorable development on prior accident years’ reserves. The expense ratio was 67.1, up from 64.0 in the prior year, due to increased investments in technology and higher bonus and profit-sharing expenses on a slightly lower premium base.

Investment Income and Realized Capital Gains

Our investment portfolio generated net investment income of $17.0 million during the second quarter of 2019, an increase of 16.6 percent from that reported for the same period in 2018. The increase in investment income was largely due to an increased asset base and higher average yields relative to the prior year. In addition, one dividend, which had historically been paid in the third quarter, was paid in the second quarter and accounted for 4.0 percent of the increase.

Yields on our fixed income investments for the second quarter of 2019 and 2018 were as follows:

	2Q 2019		2Q 2018
Pretax Yield
Taxable	3.43	%	3.19	%
Tax-Exempt	2.83	%	2.85	%
After-Tax Yield
Taxable	2.71	%	2.52	%
Tax-Exempt	2.68	%	2.70	%

We recognized $4.8 million of realized gains in the second quarter of 2019, which were comprised of $3.9 million of realized gains on equity securities from rebalancing the portfolio, $0.7 million of realized gains on the fixed income portfolio and $0.2 of miscellaneous realized gains. This compares to realized gains of $21.7 million on the equity portfolio that were partially offset by realized losses of $0.9 million in the fixed income portfolio for the same period in 2018.

32

Income Taxes

Our effective tax rate for the second quarter of 2019 was 17.1 percent, compared to 16.0 percent for the same period in 2018. Effective rates are dependent upon components of pretax earnings and the related tax effects. The effective rate was higher for the second quarter of 2019 due largely to higher levels of pre-tax earnings, which caused the tax-favored adjustments to have a smaller impact on a percentage basis in 2019 compared to the prior year.

LIQUIDITY AND CAPITAL RESOURCES

We have three primary types of cash flows: (1) cash flows from operating activities, which consist mainly of cash generated by our underwriting operations and income earned on our investment portfolio, (2) cash flows from investing activities related to the purchase, sale and maturity of investments, and (3) cash flows from financing activities that impact our capital structure, such as shareholder dividend payments and changes in debt and shares outstanding.

The following table summarizes cash flows provided by (used in) our activities for the six-month periods ended June 30, 2019 and 2018:

(in thousands)	2019		2018
Operating cash flows	$	105,347	$	100,000
Investing cash flows	$	(100,654)	$	(74,888)
Financing cash flows	$	(9,999)	$	(15,281)
Total	$	(5,306)	$	9,831

Operating activities generated positive cash flows of $105.3 million in the first six months of 2019, compared to $100.0 million in the same period last year. The increase in operating cash flows was due to increased premium receipts and investment income, which were partially offset by a larger amount of paid loss and loss adjustment expense during the period.

We have $149.2 million in debt outstanding. On October 2, 2013, we completed a public debt offering, issuing $150.0 million in senior notes maturing September 15, 2023 (a 10-year maturity), and paying interest semi-annually at the rate of 4.875 percent per annum. The notes were issued at a discount resulting in proceeds, net of discount and commission, of $148.6 million. The estimated fair value for the senior note at June 30, 2019 was $161.0 million. The fair value of our debt is estimated based on the limited observable prices that reflect thinly traded securities.

As of June 30, 2019, we had cash and other investments maturing within one year of approximately $123.4 million and an additional $410.5 million maturing between one to five years. Whereas our strategy is to be fully invested at all times, short-term investments in excess of demand deposit balances are considered a component of investment activities, and thus are classified as investments in our consolidated balance sheets.

We also maintain a revolving line of credit with JP Morgan Chase Bank N.A., which permits us to borrow up to an aggregate principal amount of $50.0 million. This facility was entered into during the second quarter of 2018 and replaced the previous $40.0 million facility which expired on May 28, 2018. Under certain conditions, the line may be increased up to an aggregate principal amount of $75.0 million. The facility has a two-year term that expires on May 24, 2020. As of and during the six-month period ended June 30, 2019, no amounts were outstanding on this facility.

Additionally, two of our insurance companies, RLI Ins. and Mt. Hawley, are members of the Federal Home Loan Bank of Chicago (FHLBC). Membership in the Federal Home Loan Bank System provides both companies access to an additional source of liquidity via a secured lending facility. Our membership allows each insurance subsidiary to determine tenor and structure at the time of borrowing. As of and during the six-month period ended June 30, 2019, there were no outstanding borrowing amounts with the FHLBC.

We believe that cash generated by operations and investments will provide sufficient sources of liquidity to meet our anticipated needs over the next 12 to 24 months. In the event they are not sufficient, we believe cash available from financing activities and other sources will provide sufficient additional liquidity.

We have not had any liquidity issues affecting our operations as we have sufficient cash flow to support operations. In addition to our bank credit facility and FHLBC membership, our highly liquid investment portfolio provides an additional source of liquidity.

33

We maintain a diversified investment portfolio representing policyholder funds that have not yet been paid out as claims, as well as the capital we hold for our shareholders. As of June 30, 2019, our investment portfolio had a balance sheet value of $2.4 billion. Invested assets at June 30, 2019 have increased $220.6 million from December 31, 2018.

As of June 30, 2019, our investment portfolio had the following asset allocation breakdown:

*Quality ratings provided by Moody’s, S&P and Fitch

**Asset-backed and commercial mortgage-backed securities

Quality is an average of each bond’s credit rating, adjusted for its relative weighting in the portfolio. As of June 30, 2019, our fixed income portfolio had the following rating distribution:

AAA	47.4	%
AA	15.2	%
A	20.4	%
BBB	10.6	%
BB	3.9	%
B	2.3	%
CCC	0.1	%
NR	0.1	%
Total	100.0	%

As of June 30, 2019, the duration of the fixed income portfolio was 4.8 years. Our fixed income portfolio remained well diversified, with 1,211 individual issues.

Our investment portfolio has limited exposure to structured asset-backed securities (ABS). As of June 30, 2019, we had $108.9 million in ABS which are pools of assets collateralized by cash flows from several types of loans, including home equity, credit cards, autos and structured bank loans in the form of collateralized loan obligations (CLOs).

As of June 30, 2019, we had $43.0 million in commercial mortgage backed securities (CMBS) and $408.2 million in mortgage backed securities backed by government sponsored enterprises (GSEs - Freddie Mac, Fannie Mae and Ginnie Mae). Excluding the GSE backed MBS, our exposure to ABS and CMBS was 6.3 percent of our investment portfolio at quarter end.

We had $726.8 million in corporate fixed income securities as of June 30, 2019, which includes $83.5 million invested in a high yield credit strategy. This high-yield portfolio consists of floating rate bank loans and bonds that are below investment grade in credit quality and offer incremental yield over our core fixed income portfolio.

34

We also maintain an allocation to municipal fixed income securities. As of June 30, 2019, we had $336.6 million in municipal securities. Approximately 83 percent of our municipal bond portfolio maintains an ‘AA’ or better rating, while 99 percent of the municipal bond portfolio is rated ‘A’ or better.

Our equity portfolio had a fair value of $421.8 million as of June 30, 2019 and is also a source of liquidity. The securities within the equity portfolio remain primarily invested in large-cap issues with a focus on dividend income. In the equity portfolio, the strategy remains one of value investing, with security selection taking precedence over market timing.

As of June 30, 2019, our equity portfolio had a dividend yield of 2.4 percent, compared to 1.9 percent for the S&P 500 index. Because of the corporate dividend-received-deduction applicable to our dividend income, we pay an effective tax rate of 13.1 percent on dividends, compared to 21.0 percent on taxable interest and 5.3 percent on municipal bond interest income. The equity portfolio is managed in a diversified and granular manner, with 243 individual securities and three ETF positions. No single stock exposure is greater than 2 percent of the equity portfolio.

We had $55.2 million of other invested assets at June 30, 2019, including investments in low income housing tax credit partnerships, membership in the Federal Home Loan Bank of Chicago (FHLBC) and investments in private funds. As of June 30, 2019, $16.3 million of investments were pledged as collateral with the FHLBC to ensure timely access to the secured lending facility that ownership of FHLBC stock provides. As of and during the six month period ending June 30, 2019, there were no outstanding borrowings with the FHLBC.

Our investment portfolio does not have any exposure to derivatives.

Our capital structure is comprised of equity and debt outstanding. As of June 30, 2019, our capital structure consisted of $149.2 million in 10-year maturity senior notes maturing in 2023 (debt) and $959.9 million of shareholders’ equity. Debt outstanding comprised 13.5 percent of total capital as of June 30, 2019. Interest and fees on debt obligations totaled $3.7 million during the first half of 2019, the same amount as the previous year. We have incurred interest expense on debt at an average annual interest rate of 4.91 percent for the six-month periods ended June 30, 2019 and 2018.

We paid a regular quarterly cash dividend of $0.23 per share on June 20, 2019, a $0.01 increase over the prior quarter. We have increased dividends in each of the last 44 years.

Our three insurance subsidiaries are subsidiaries of RLI Corp, with RLI Ins. as the first-level, or principal, insurance subsidiary. At the holding company (RLI Corp.) level, we rely largely on dividends from our insurance company subsidiaries to meet our obligations for paying principal and interest on outstanding debt, corporate expenses and dividends to RLI Corp. shareholders. As discussed further below, dividend payments to RLI Corp. from our principal insurance subsidiary are restricted by state insurance laws as to the amount that may be paid without prior approval of the insurance regulatory authorities of Illinois. As a result, we may not be able to receive dividends from such subsidiary at times and in amounts necessary to pay desired dividends to RLI Corp. shareholders. On a GAAP basis, as of June 30, 2019, our holding company had $959.9 million in equity. This includes amounts related to the equity of our insurance subsidiaries, which is subject to regulatory restrictions under state insurance laws. The unrestricted portion of holding company net assets is comprised primarily of investments and cash, including $46.3 million in liquid assets, which approximates annual holding company expenditures. Unrestricted funds at the holding company are available to fund debt interest, general corporate obligations and dividend payments to our shareholders. If necessary, the holding company also has other potential sources of liquidity that could provide for additional funding to meet corporate obligations or pay shareholder dividends, which include a revolving line of credit, as well as access to capital markets.

Ordinary dividends, which may be paid by our principal insurance subsidiary without prior regulatory approval, are subject to certain limitations based upon statutory income, surplus and earned surplus. The maximum ordinary dividend distribution from our principal insurance subsidiary in a rolling 12-month period is limited by Illinois law to the greater of 10 percent of RLI Ins. policyholder surplus, as of December 31 of the preceding year, or the net income of RLI Ins. for the 12-month period ending December 31 of the preceding year. Ordinary dividends are further restricted by the requirement that they be paid from earned surplus. Any dividend distribution in excess of the ordinary dividend limits is deemed extraordinary and requires prior approval from the Illinois Department of Insurance (IDOI). RLI Ins. did not pay any dividends to RLI Corp in the first six months of 2019. In 2018, our principal insurance subsidiary paid ordinary dividends totaling $13.0 million and extraordinary dividends totaling $110.0 million. Given the amount of dividends paid during the prior rolling 12-month period, the net assets of our principal insurance subsidiary are restricted until the fourth quarter of 2019 and cannot be distributed to RLI Corp. without prior approval from the IDOI. In addition to restrictions from our principal subsidiary’s insurance regulator,

35

we also consider internal models and how capital adequacy is defined by our rating agencies in determining amounts available for distribution. However, as discussed above, RLI Corp. had the necessary amount of unrestricted liquid net assets on hand at June 30, 2019 to cover normal annual holding company expenditures as they are incurred and become payable.

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 equity prices, interest rates, foreign currency exchange rates and commodity prices. Historically, 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 have limited exposure to both foreign currency risk and commodity risk.

Credit risk is the potential loss resulting from adverse changes in an issuer’s ability to repay its debt obligations. We monitor our portfolio to ensure that credit risk does not exceed prudent levels. We have consistently invested in high credit quality, investment grade securities. Our fixed maturity portfolio has an average rating of “AA-,” with 83 percent rated “A” or better by at least two nationally recognized rating organizations.

On an overall basis, our exposure to market risk has not significantly changed from that reported in our December 31, 2018 Annual Report on Form 10-K.

ITEM 4. Controls and Procedures

We maintain a system of controls and procedures designed to provide reasonable assurance as to the reliability of the financial statements and other disclosures included in this report, as well as to safeguard assets from unauthorized use or disposition. An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures was performed, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that these disclosure controls and procedures are effective, as of the end of the period covered by this report.

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired control objective, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. We believe that our disclosure controls and procedures provide such reasonable assurance.

No changes were made to our internal control over financial reporting during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

6 Months Ended

Jun. 30, 2019

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A. DESCRIPTION OF BUSINESS

RLI Corp. (the Company) is an insurance holding company that was organized in 1965. As reported in previous SEC filings, RLI Corp. changed its state of incorporation from the State of Illinois to the State of Delaware on May 4, 2018 (the Reincorporation). The Reincorporation was effected by merging RLI Corp., an Illinois corporation (RLI Illinois) into RLI Corp., a Delaware corporation (RLI Delaware). Each outstanding share of RLI Illinois common stock, which had a par value of $1.00 per share, was automatically converted into one outstanding share of RLI Delaware common stock, with a par value of $0.01 per share. In order to reflect the new par value of common stock on the balance sheet, a $66.5 million reclassification from common stock to paid-in-capital was made during the second quarter of 2018. For more information on the Reincorporation, see RLI Corp.’s Form 8-K filed on May 7, 2018.

B. BASIS OF PRESENTATION

The unaudited condensed consolidated interim financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) for interim financial reporting and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. As such, these unaudited condensed consolidated interim financial statements should be read in conjunction with our 2018 Annual Report on Form 10-K. Management believes that the disclosures are adequate to make the information presented not misleading, and all normal and recurring adjustments necessary to present fairly the financial position at June 30, 2019 and the results of operations of RLI Corp. and subsidiaries for all periods presented have been made. The results of operations for any interim period are not necessarily indicative of the operating results for a full year. Certain reclassifications were made to 2018 to conform to the classifications used in the current year.

The preparation of the unaudited condensed consolidated interim financial statements requires management to make estimates and assumptions relating to the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated interim financial statements and the reported amounts of revenue and expenses during the period. These estimates are inherently subject to change and actual results could differ significantly from these estimates.

C. ADOPTED ACCOUNTING STANDARDS

ASU 2016-02, Leases (Topic 842)

ASU 2016-02 was issued to improve the financial reporting of leasing transactions. Under previous guidance for lessees, leases were only included on the balance sheet if certain criteria, classifying the agreement as a capital lease, were met. This update requires the recognition of a right-of-use asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. For operating leases, the asset and liability are expensed over the lease term on a straight-line basis, with all cash flows included in the operating section of the statement of cash flows. For finance leases, interest on the lease liability is recognized separately from the amortization of the right-of-use asset in the statement of earnings and the repayment of the principal portion of the lease liability is classified as a financing activity while the interest component is included in the operating section of the statement of cash flows.

We adopted ASU 2016-02, ASU 2018-10 Codification Improvements to Topic 842: Leases and ASU 2018-11 Leases (Topic 842): Targeted Improvements on January 1, 2019. We applied the standards using the alternative transition method provided by ASU 2018-11 under which leases were recognized at the date of adoption and a cumulative-effective adjustment to the opening balance of retained earnings would have been recognized in the period of adoption. As the standard did not have an impact on our net earnings, no adjustment to the opening balance of retained earnings was required. As of June 30, 2019, $24.4 million of right-of-use assets and $26.6 million of lease liabilities were included in the other assets and other liabilities line items of the balance sheet, respectively, as a result of the adoption of this update. We implemented controls for the adoption of the standard and the ongoing monitoring of the right-of-use asset and lease liability, but they did not materially affect our internal control over financial reporting.

ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities

Under previous guidance, the amortization period for callable debt securities held at a premium was generally the contractual life of the instrument. However, if an entity had a large number of similar loans, it could consider estimates of future principal prepayments. For those who chose not to incorporate an estimate of future prepayments, ASU 2017-08 shortens the amortization period for premium on debt securities to the earliest call date, rather than the maturity date, to align the amortization method with how the securities are quoted, priced and traded. After the earliest call date, if the call option is not exercised, the entity shall reset the effective yield using the payment terms of the debt security. Any excess of the amortized cost basis over the amount payable will be amortized to the next call date or to maturity if there are no other call dates. The method of accounting for a discount does not change and will continue to be amortized over the life of the bond.

We adopted ASU 2017-08 on January 1, 2019 using a modified-retrospective approach. As we had been incorporating estimates of future principal prepayments when calculating the effective yield for bonds carrying a premium under the old guidance, the adoption of this update did not have a material impact on our financial statements.

ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting

ASU 2018-07 was issued to simplify the accounting for share-based transactions by expanding the scope of Topic 718 from only being applicable to share-based payments to employees to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, nonemployee share-based transactions will be measured by estimating the fair value of the equity instruments at the grant date, taking into consideration the probability of satisfying performance conditions. We adopted ASU 2018-07 on January 1, 2019. Our long-term incentive plan limits the awards of share-based payments to employees and directors of the Company. As our share-based compensation expense to nonemployee directors was $0.3 million in the first six months of 2019, the standard did not have a material impact on our financial statements.

D. PROSPECTIVE ACCOUNTING STANDARDS

ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

ASU 2016-13 was issued to provide more decision-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, including reinsurance balances recoverable, to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net earnings. 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 in which the guidance is effective. This update will have the most impact on our available-for-sale fixed income portfolio and reinsurance balances recoverable. However, as our fixed income portfolio is weighted towards higher rated bonds (83.0 percent rated A or better at June 30, 2019) and we purchase reinsurance from financially strong reinsurers for which we already have an allowance for uncollectible reinsurance amounts, we do not expect that the effect of adoption will be material.

ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement

ASU 2018-13 modifies the disclosure requirements for assets and liabilities measured at fair value. The requirements to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements have all been removed. However, the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period must be disclosed along with the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements (or other quantitative information if it is more reasonable). Finally, for investments measured at net asset value, the requirements have been modified so that the timing of

liquidation and the date when restrictions from redemption might lapse are only disclosed if the investee has communicated the timing to the entity or announced the timing publicly.

This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. As the amendments are only disclosure related and we do not currently have any assets or liabilities that are measured based on Level 3 inputs, our financial statements will not be materially impacted by this update.

ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract

ASU 2018-15 requires a customer in a cloud computing arrangement (i.e. hosting arrangement) that is a service contract to follow the internal-use software guidance to determine which implementation costs to capitalize as assets or expense as incurred. Relevant implementation costs in the development stage are capitalized, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. Capitalized costs are expensed over the term of the hosting arrangement. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted. This update can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are currently evaluating how the adoption of this ASU will affect our financial statements.

E. INTANGIBLE ASSETS

Goodwill and intangible assets totaled $54.3 million and $54.5 million at June 30, 2019 and December 31, 2018, respectively, as detailed in the following table:

Goodwill and Intangible Assets		June 30,		December 31,
(in thousands)		2019		2018
Goodwill
Energy surety	$	25,706	$	25,706
Miscellaneous and contract surety		15,110		15,110
Small commercial		5,246		5,246
Total goodwill	$	46,062	$	46,062
Intangibles
State insurance licenses	$	7,500	$	7,500
Definite-lived intangibles, net of accumulated amortization of $3,266 at 6/30/19 and $3,062 at 12/31/18		768		972
Total intangibles	$	8,268	$	8,472
Total goodwill and intangibles	$	54,330	$	54,534

All definite-lived intangible assets are amortized against future operating results based on their estimated useful lives. Amortization of intangible assets was $0.1 million for the second quarter of 2019 and $0.2 million for the six-month period ended June 30, 2019, the same as for the comparable periods in 2018.

Annual impairment assessment was performed on our energy surety goodwill, miscellaneous and contract surety goodwill, small commercial goodwill and state insurance license indefinite-lived intangible asset during the second quarter of 2019. Based upon these reviews, none of the assets were impaired. In addition, as of June 30, 2019, there were no triggering events that would suggest an updated review was necessary on the above-mentioned goodwill and intangible assets.

Adverse loss experience triggered the need to test the medical professional liability reporting unit during the first quarter of 2018, which resulted in a $4.4 million non-cash impairment charge. A fair value for the medical professional liability reporting unit’s agency relationships, carried as a definite-lived intangible, was determined by using a discounted cash flow valuation. The carrying value exceeded the fair value, resulting in a $0.8 million non-cash impairment charge. A fair value for the medical professional liability reporting unit’s goodwill was determined by using a weighted average of a market approach and discounted cash flow valuation. The carrying value exceeded the fair value, resulting in a $3.6 million non-cash

impairment charge. Subsequent to the first quarter 2018 impairment, the medical professional liability reporting unit had no remaining goodwill or intangible assets. All impairment charges were recorded as net realized losses in the consolidated statement of earnings.

F. EARNINGS PER SHARE

Basic earnings per share (EPS) excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock or common stock equivalents were exercised or converted into common stock. When inclusion of common stock equivalents increases the earnings per share or reduces the loss per share, the effect on earnings is anti-dilutive. Under these circumstances, the diluted net earnings or net loss per share is computed excluding the common stock equivalents. The following represents a reconciliation of the numerator and denominator of the basic and diluted EPS computations contained in the unaudited condensed consolidated interim financial statements:

	For the Three-Month Period					For the Three-Month Period

G. COMPREHENSIVE EARNINGS

Our comprehensive earnings include net earnings plus after-tax unrealized gains and losses on our fixed income portfolio. In reporting other comprehensive earnings on a net basis in the statement of earnings, we used the federal statutory tax rate of 21 percent.

Unrealized gains, net of tax, on the fixed income portfolio for the first six months of 2019 were $57.2 million, compared to $34.1 million of unrealized losses, net of tax, during the same period last year. Unrealized gains in the first six months of 2019 were attributable to declining interest rates, which increased the fair value of securities held in the fixed income portfolio. In contrast, rising interest rates decreased the fair value of securities held in the fixed income portfolio in the first six months of 2018.

The following table illustrates the changes in the balance of each component of accumulated other comprehensive earnings for each period presented in the unaudited condensed consolidated interim financial statements:

(in thousands)	For the Three-Month Periods				For the Six-Month Periods
	Ended June 30,				Ended June 30,
Unrealized Gains/Losses on Available-for-Sale Securities	2019		2018		2019		2018

Ending balance	$	42,593	$	(14,648)	$	42,593	$	(14,648)

In 2018, the adoption of accounting standards resulted in adjustments to accumulated other comprehensive earnings. ASU 2016-01 required equity investments to be measured at fair value with changes in fair value recognized in net earnings. A cumulative-effect adjustment was made as of the beginning of 2018, which moved $142.2 million of net unrealized gains and losses on equity securities from accumulated other comprehensive earnings to retained earnings.

ASU 2018-02 addressed issues arising from the enactment of the Tax Cuts and Jobs Act of 2017. Accounting guidance required deferred tax items to be revalued based on the new tax laws with the changes included in net earnings. Since other comprehensive earnings was not affected by the revaluation of the deferred tax items, the accumulated other comprehensive earnings balance was reflective of the historic tax rate instead of the newly enacted rate, which created a stranded tax effect. ASU 2018-02 allowed for the reclassification of our $3.7 million stranded tax effect out of accumulated other comprehensive earnings into retained earnings.

The sale or other-than-temporary impairment of an available-for-sale security results in amounts being reclassified from accumulated other comprehensive earnings to current period net earnings. The effects of reclassifications out of accumulated other comprehensive earnings by the respective line items of net earnings are presented in the following table:

INVESTMENTS

2. INVESTMENTS

Our investments are primarily composed of fixed income debt securities and common stock equity securities. We carry our equity securities at fair value and categorize all of our debt securities as available-for-sale, which are carried at fair value. When available, we obtain quoted market prices to determine fair value for our investments. If a quoted market price is not available, fair value is estimated using a secondary pricing source or using quoted market prices of similar securities. We have no investment securities for which fair value is determined using Level 3 inputs as defined in note 3 to the unaudited condensed consolidated interim financial statements, “Fair Value Measurements.”

Fixed Income Securities - Available-for-Sale

Unrealized Losses on Fixed Income Securities

We conduct and document periodic reviews of all fixed income securities with unrealized losses to evaluate whether the impairment is other-than-temporary. The following tables are used as part of our impairment analysis and illustrate the total value of fixed income securities that were in an unrealized loss position as of June 30, 2019 and December 31, 2018. The tables segregate the securities based on type, noting the fair value, amortized cost and unrealized loss on each category of investment as well as in total. The tables further classify the securities based on the length of time they have been in an unrealized loss position. As of June 30, 2019, unrealized losses on fixed income securities, as shown in the following tables, were 0.2 percent of total invested assets. Unrealized losses decreased through the first six months of 2019, as interest rates decreased from the end of 2018, increasing the fair value of securities held in the fixed income portfolio.

Evaluating Fixed Income Securities for OTTI

The fixed income portfolio contained 279 securities in an unrealized loss position as of June 30, 2019. The $3.6 million in associated unrealized losses represents 0.2 percent of the fixed income portfolio’s cost basis. Of these 279 securities, 122 have been in an unrealized loss position for 12 consecutive months or longer. All fixed income securities in the investment portfolio continue to pay the expected coupon payments under the contractual terms of the securities. Any credit-related impairment on fixed income securities we do not plan to sell and for which we are not more likely than not to be required to sell is recognized in net earnings, with the non-credit related impairment recognized in comprehensive earnings. Based on our analysis, our fixed income portfolio is of high credit quality and we believe we will recover the amortized cost basis of our fixed income securities. We continually monitor the credit quality of our fixed income investments to assess if it is probable that we will receive our contractual or estimated cash flows in the form of principal and interest. We did not recognize any other-than-temporary impairment (OTTI) losses in earnings on the fixed income portfolio in the first six months of 2019. Comparatively, we recognized $0.1 million in OTTI losses in earnings on one fixed income security that we no longer had the intent to hold in the same period in 2018. There were no OTTI losses recognized in other comprehensive earnings on the fixed income portfolio for the periods presented.

Unrealized Gains and Losses on Equity Securities

Unrealized gains recognized on equity securities still held as of June 30, 2019 were $12.9 million during the second quarter and $54.8 million during the first half of 2019. Comparatively, unrealized gains recognized on equity securities still held as of June 30, 2018 were $9.1 million during the second quarter, while unrealized losses were $4.8 million during the first half of 2018.

Other Invested Assets

We had $55.2 million of other invested assets at June 30, 2019, compared to $51.5 million at the end of 2018. Other invested assets include investments in low income housing tax credit partnerships (LIHTC), membership in the Federal Home Loan Bank of Chicago (FHLBC) and investments in private funds. Our LIHTC investments are carried at amortized cost and our investment in FHLBC stock is carried at cost. Due to the nature of the LIHTC and our membership in the FHLBC, their carrying amounts approximate fair value. The private funds are carried at fair value, using each investment’s net asset value.

Our LIHTC interests had a balance of $19.4 million at June 30, 2019, compared to $20.3 million at December 31, 2018 and recognized a total tax benefit of $0.6 million during the second quarter of 2019, the same as the prior year. For the six-month periods ended June 30, 2019 and 2018, our LIHTC interests recognized a total benefit of $1.2 million and $1.1 million, respectively. Our unfunded commitment for our LIHTC investments totaled $7.1 million at June 30, 2019 and will be paid out in installments through 2035.

As of June 30, 2019, $16.3 million of investments were pledged as collateral with the FHLBC to ensure timely access to the secured lending facility that ownership of FHLBC stock provides. As of and during the six month period ending June 30, 2019, there were no outstanding borrowings with the FHLBC.

We had $12.4 million of unfunded commitments related to our investments in private funds at June 30, 2019. Additionally, our interest in these investments is generally restricted from being transferred or otherwise redeemed without prior consent by the respective entities. An IPO would allow for the transfer of interest in some situations, while the timed dissolution of the partnership would trigger redemption in others.

Cash and Short-term Investments

Cash consists of uninvested balances in bank accounts. We had a cash balance of $24.8 million at June 30, 2019, compared to $30.1 million at the end of 2018. As of June 30, 2019, we had $47.4 million of short-term investments that were carried at cost and approximated fair value, compared to $11.6 million at December 31, 2018.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

3. FAIR VALUE MEASUREMENTS

Assets and Liabilities Recorded at Fair Value on a Recurring Basis

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. We determined the fair value of certain financial instruments based on their underlying characteristics and relevant transactions in the marketplace. We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The following are the levels of the fair value hierarchy and a brief description of the type of valuation inputs that are used to establish each level. Financial assets are classified based upon the lowest level of significant input that is used to determine fair value.

Pricing Level 1 is applied to valuations based on readily available, unadjusted quoted prices in active markets for identical assets.

Pricing Level 2 is applied to valuations based upon quoted prices for similar assets in active markets, quoted prices for identical or similar assets in inactive markets; or valuations based on models where the significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities) or can be corroborated by observable market data.

Pricing Level 3 is applied to valuations that are derived from techniques in which one or more of the significant inputs are unobservable.

As a part of management’s process to determine fair value, we utilize widely recognized, third-party pricing sources to determine our fair values. We have obtained an understanding of the third-party pricing sources’ valuation methodologies and inputs. The following is a description of the valuation techniques used for financial assets that are measured at fair value, including the general classification of such assets pursuant to the fair value hierarchy.

Corporate, Agencies, Government and Municipal Bonds: The pricing vendor employs a multi-dimensional model which uses standard inputs including (listed in approximate order of priority for use) benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, market bids/offers and other reference data. The pricing vendor also monitors market indicators, as well as industry and economic events. All bonds valued using these techniques are classified as Level 2. All corporate, agency, government and municipal securities were deemed Level 2.

Mortgage-backed Securities (MBS)/Commercial Mortgage-backed Securities (CMBS) and Asset-backed Securities (ABS): The pricing vendor evaluation methodology includes principally interest rate movements and new issue data. Evaluation of the tranches (non-volatile, volatile or credit sensitivity) is based on the pricing vendors’ interpretation of accepted modeling and pricing conventions. This information is then used to determine the cash flows for each tranche, benchmark yields, prepayment assumptions and to incorporate collateral performance. To evaluate MBS and CMBS volatility, an option adjusted spread model is used in combination with models that simulate interest rate paths to determine market price information. This process allows the pricing vendor to obtain evaluations of a broad universe of securities in a way that reflects changes in yield curve, index rates, implied volatility, mortgage rates and recent trade activity. MBS/CMBS and ABS with corroborated, observable inputs are classified as Level 2. All of our MBS/CMO and ABS are deemed Level 2.

For all of our fixed income securities classified as Level 2, as described above, we periodically conduct a review to assess the reasonableness of the fair values provided by our pricing services. Our review consists of a two-pronged approach. First, we compare prices provided by our pricing services to those provided by an additional source. In some cases, we obtain prices from securities brokers and compare them to the prices provided by our pricing services. In both comparisons, if discrepancies are found, we compare our prices to actual reported trade data for like securities. No changes to the fair values supplied by our pricing services have occurred as a result of our reviews. Based on these assessments, we have determined that the fair values of our Level 2 securities provided by our pricing services are reasonable.

Common Stock: All but one of our common stock holdings are traded on an exchange. Exchange traded equities have readily observable price levels and are classified as Level 1 (fair value based on quoted market prices). Pricing for the equity security not traded on an exchange is provided by a third-party pricing source and is classified as Level 2.

Due to the relatively short-term nature of cash, short-term investments, accounts receivable and accounts payable, their carrying amounts are reasonable estimates of fair value. Our investments in private funds, classified as other invested assets, are measured using the investment’s net asset value per share and are not categorized within the fair value hierarchy.

Assets measured at fair value in the accompanying unaudited condensed consolidated interim financial statements on a recurring basis are summarized below:

INCOME TAXES

5. INCOME TAXES

Our effective tax rate for the three and six-month periods ended June 30, 2019 was 17.1 percent and 18.9 percent, respectively, compared to 16.0 percent and 15.7 percent, respectively, for the same periods in 2018. Effective rates are dependent upon components of pretax earnings and the related tax effects. The effective rate was higher for the first six months of 2019 due largely to higher levels of pre-tax earnings, which caused the tax-favored adjustments to be smaller on a percentage basis in 2019 compared to the prior year.

Income tax expense attributable to income from operations for the three and six-month periods ended June 30, 2019 and 2018 differed from the amounts computed by applying the U.S. federal tax rate of 21 percent to pretax income by the items detailed in the below table. In interim periods, income taxes are adjusted to reflect the effective tax rate we anticipate for the year, with adjustments flowing through the other items line.

STOCK BASED COMPENSATION

STOCK BASED COMPENSATION

6. STOCK BASED COMPENSATION

Our RLI Corp. Long-Term Incentive Plan (2010 LTIP) was in place from 2010 to 2015. The 2010 LTIP provided for equity-based compensation, including stock options, up to a maximum of 4,000,000 shares of common stock (subject to adjustment for changes in our capitalization and other events). Between 2010 and 2015, we granted 2,878,000 stock options under the 2010 LTIP. The 2010 LTIP was replaced in 2015.

In 2015, our shareholders approved the 2015 RLI Corp. Long-Term Incentive Plan (2015 LTIP), which provides for equity-based compensation and replaced the 2010 LTIP. In conjunction with the adoption of the 2015 LTIP, effective May 7, 2015, options were no longer granted under the 2010 LTIP. Awards under the 2015 LTIP may be in the form of restricted stock, restricted stock units, stock options (non-qualified only), stock appreciation rights, performance units as well as other stock-based awards. Eligibility under the 2015 LTIP is limited to employees and directors of the Company or any affiliate. The granting of awards under the 2015 LTIP is solely at the discretion of the board of directors. The maximum number of shares of common stock available for distribution under the 2015 LTIP is 4,000,000 shares (subject to adjustment for changes in our capitalization and other events). Since the plan’s approval in 2015, we have granted 2,217,710 awards under the 2015 LTIP, including 314,080 thus far in 2019.

Stock Options

Under the 2015 LTIP, as under the 2010 LTIP, we grant stock options for shares with an exercise price equal to the fair market value of the shares at the date of grant (subject to adjustments for changes in our capitalization, special dividends and other events as set forth in such plans). Options generally vest and become exercisable ratably over a five-year period and expire eight years after grant.

For most participants, the requisite service period and vesting period will be the same. For participants who are retirement eligible, defined by the plan as those individuals whose age and years of service equals 75, the requisite service period is deemed to be met and options are immediately expensed on the date of grant. For participants who will become retirement eligible during the vesting period, the requisite service period over which expense is recognized is the period between the grant date and the attainment of retirement eligibility. Shares issued upon option exercise are newly issued shares.

The following tables summarize option activity for the periods ended June 30, 2019 and 2018:

				Weighted
		Weighted		Average	Aggregate
	Number of	Average		Remaining	Intrinsic
	Options	Exercise		Contractual	Value

				Weighted

	Outstanding	Price		Life	(in 000’s)
Outstanding options at January 1, 2018	2,257,015	$	46.80
Options granted	367,500	$	63.27
Options exercised	(337,000)	$	31.60		$	11,151
Options canceled/forfeited	(5,200)	$	62.04
Outstanding options at June 30, 2018	2,282,315	$	51.66	5.34	$	33,224
Exercisable options at June 30, 2018	996,265	$	44.04	3.89	$	22,089

The majority of our stock options are granted annually at our regular board meeting in May. In addition, options are approved at the May meeting for quarterly grants to certain retirement eligible employees. Since stock option grants to retirement eligible employees are fully expensed when issued, the approach allows for a more even expense distribution throughout the year.

Thus far in 2019, 292,150 stock options were granted with a weighted average exercise price of $80.36 and a weighted average fair value of $13.33. We recognized $1.4 million of expense in the second quarter of 2019 and $2.4 million in the first six months of 2019 related to options vesting. Since options granted under our 2015 LTIP are non-qualified, we recorded a tax benefit of $0.3 million in the second quarter of 2019 and $0.5 million in the first six months of 2019 related to this compensation expense. Total unrecognized compensation expense relating to outstanding and unvested options was $6.7 million, which will be recognized over the remainder of the vesting period. Comparatively, we recognized $1.3 million of compensation expense in the second quarter of 2018 and $2.3 million in the first six months of 2018. We recorded a tax benefit of $0.3 million in the second quarter of 2018 and $0.5 million in the first six months of 2018 related to this compensation expense.

The fair value of options was estimated using a Black-Scholes based option pricing model with the following weighted average grant-date assumptions and weighted average fair values as of June 30:

	2019			2018
Weighted-average fair value of grants	$	13.33		$	10.20
Risk-free interest rates		2.42	%		2.69	%
Dividend yield		2.69	%		3.15	%
Expected volatility		22.71	%		22.88	%
Expected option life		4.96	years		5.06	years

The risk-free rate was determined based on U.S. treasury yields that most closely approximated the option’s expected life. The dividend yield was determined based on the average annualized quarterly dividends paid during the most recent five-year period and incorporated a consideration for special dividends paid in recent history. The expected volatility was calculated based on the median of the rolling volatilities for the expected life of the options. The expected option life was determined based on historical exercise behavior and the assumption that all outstanding options will be exercised at the midpoint of the current date and remaining contractual term, adjusted for the demographics of the current year’s grant.

Restricted Stock Units

In addition to stock options, restricted stock units (RSUs) are granted with a value equal to the closing stock price of the Company’s stock on the dates the units are granted. Generally, these units have a three-year cliff vesting. When participants terminate employment with the Company after having met the definition of retirement under the 2015 LTIP, defined as those individuals whose age and years of service equals 75, the RSUs will become fully vested. In addition, the RSUs have dividend participation, which accrue as additional units and are settled with granted stock units at the end of the vesting period.

As of June 30, 2019, 45,350 RSUs have been granted to employees under the 2015 LTIP, including 15,275 in 2019, and 44,431 remain outstanding. We recognized $0.2 million of expense on these units in the second quarter of 2019 and $0.3 million in the first six months of 2019. Total unrecognized compensation expense relating to outstanding and unvested RSUs was $1.5 million, which will be recognized over the remainder of the vesting period. Comparatively, we recognized $0.1 million of expense in the second quarter of 2018 and $0.2 million in the first six months of 2018.

In 2018 and 2019, each outside director received RSUs with a fair market value of $50,000 on the date of grant as part of annual director compensation. Director RSUs vest one year from the date of grant. As of June 30, 2019, 15,085 restricted stock units have been granted to directors under the 2015 LTIP, including 6,655 in 2019, and 7,402 remain outstanding. We recognized $0.2 million of compensation expense on these units in the second quarter of 2019 and $0.3 million in the first six months of 2019. Total unrecognized compensation expense relating to outstanding and unvested director RSUs was $0.4 million, which will be recognized over the remainder of the vesting period. Comparatively, we recognized $0.1 million of compensation expense for the three and six-month periods ended June 30, 2018.

LEASES

8. LEASES

We adopted ASU 2016-02, Leases on January 1, 2019, which resulted in the recognition of operating leases on the balance sheet in 2019 and forward. See note 1c for more information on the adoption of the ASU. Right-of-use assets are included in the other assets line item and lease liabilities are included in the other liabilities line item of the consolidated balance sheet. We determine if a contract contains a lease at inception and recognize operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments at the commencement date. As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. Lease agreements may include options to extend or terminate. The options are exercised at our discretion and are included in operating lease liabilities if it is reasonably certain the option will be exercised. Lease agreements have lease and non-lease components, which are accounted for as a single lease component. Lease expense is recognized on a straight-line basis over the lease term.

The Company’s operating lease obligations are for branch office facilities. Our leases have remaining lease terms of 1 to 16 years. Expenses associated with leases totaled $6.9 million in 2018, $6.8 million in 2017 and $6.4 million in 2016. The components of lease expense and other lease information as of and during the three and six-month period ended June 30, 2019 are as follows:

DESCRIPTION OF BUSINESS

A. DESCRIPTION OF BUSINESS

RLI Corp. (the Company) is an insurance holding company that was organized in 1965. As reported in previous SEC filings, RLI Corp. changed its state of incorporation from the State of Illinois to the State of Delaware on May 4, 2018 (the Reincorporation). The Reincorporation was effected by merging RLI Corp., an Illinois corporation (RLI Illinois) into RLI Corp., a Delaware corporation (RLI Delaware). Each outstanding share of RLI Illinois common stock, which had a par value of $1.00 per share, was automatically converted into one outstanding share of RLI Delaware common stock, with a par value of $0.01 per share. In order to reflect the new par value of common stock on the balance sheet, a $66.5 million reclassification from common stock to paid-in-capital was made during the second quarter of 2018. For more information on the Reincorporation, see RLI Corp.’s Form 8-K filed on May 7, 2018.

BASIS OF PRESENTATION

B. BASIS OF PRESENTATION

The unaudited condensed consolidated interim financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) for interim financial reporting and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. As such, these unaudited condensed consolidated interim financial statements should be read in conjunction with our 2018 Annual Report on Form 10-K. Management believes that the disclosures are adequate to make the information presented not misleading, and all normal and recurring adjustments necessary to present fairly the financial position at June 30, 2019 and the results of operations of RLI Corp. and subsidiaries for all periods presented have been made. The results of operations for any interim period are not necessarily indicative of the operating results for a full year. Certain reclassifications were made to 2018 to conform to the classifications used in the current year.

The preparation of the unaudited condensed consolidated interim financial statements requires management to make estimates and assumptions relating to the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated interim financial statements and the reported amounts of revenue and expenses during the period. These estimates are inherently subject to change and actual results could differ significantly from these estimates.

ADOPTED ACCOUNTING STANDARDS

C. ADOPTED ACCOUNTING STANDARDS

ASU 2016-02, Leases (Topic 842)

ASU 2016-02 was issued to improve the financial reporting of leasing transactions. Under previous guidance for lessees, leases were only included on the balance sheet if certain criteria, classifying the agreement as a capital lease, were met. This update requires the recognition of a right-of-use asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. For operating leases, the asset and liability are expensed over the lease term on a straight-line basis, with all cash flows included in the operating section of the statement of cash flows. For finance leases, interest on the lease liability is recognized separately from the amortization of the right-of-use asset in the statement of earnings and the repayment of the principal portion of the lease liability is classified as a financing activity while the interest component is included in the operating section of the statement of cash flows.

We adopted ASU 2016-02, ASU 2018-10 Codification Improvements to Topic 842: Leases and ASU 2018-11 Leases (Topic 842): Targeted Improvements on January 1, 2019. We applied the standards using the alternative transition method provided by ASU 2018-11 under which leases were recognized at the date of adoption and a cumulative-effective adjustment to the opening balance of retained earnings would have been recognized in the period of adoption. As the standard did not have an impact on our net earnings, no adjustment to the opening balance of retained earnings was required. As of June 30, 2019, $24.4 million of right-of-use assets and $26.6 million of lease liabilities were included in the other assets and other liabilities line items of the balance sheet, respectively, as a result of the adoption of this update. We implemented controls for the adoption of the standard and the ongoing monitoring of the right-of-use asset and lease liability, but they did not materially affect our internal control over financial reporting.

ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities

Under previous guidance, the amortization period for callable debt securities held at a premium was generally the contractual life of the instrument. However, if an entity had a large number of similar loans, it could consider estimates of future principal prepayments. For those who chose not to incorporate an estimate of future prepayments, ASU 2017-08 shortens the amortization period for premium on debt securities to the earliest call date, rather than the maturity date, to align the amortization method with how the securities are quoted, priced and traded. After the earliest call date, if the call option is not exercised, the entity shall reset the effective yield using the payment terms of the debt security. Any excess of the amortized cost basis over the amount payable will be amortized to the next call date or to maturity if there are no other call dates. The method of accounting for a discount does not change and will continue to be amortized over the life of the bond.

We adopted ASU 2017-08 on January 1, 2019 using a modified-retrospective approach. As we had been incorporating estimates of future principal prepayments when calculating the effective yield for bonds carrying a premium under the old guidance, the adoption of this update did not have a material impact on our financial statements.

ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting

ASU 2018-07 was issued to simplify the accounting for share-based transactions by expanding the scope of Topic 718 from only being applicable to share-based payments to employees to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, nonemployee share-based transactions will be measured by estimating the fair value of the equity instruments at the grant date, taking into consideration the probability of satisfying performance conditions. We adopted ASU 2018-07 on January 1, 2019. Our long-term incentive plan limits the awards of share-based payments to employees and directors of the Company. As our share-based compensation expense to nonemployee directors was $0.3 million in the first six months of 2019, the standard did not have a material impact on our financial statements.

PROSPECTIVE ACCOUNTING STANDARDS

D. PROSPECTIVE ACCOUNTING STANDARDS

ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

ASU 2016-13 was issued to provide more decision-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, including reinsurance balances recoverable, to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net earnings. 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 in which the guidance is effective. This update will have the most impact on our available-for-sale fixed income portfolio and reinsurance balances recoverable. However, as our fixed income portfolio is weighted towards higher rated bonds (83.0 percent rated A or better at June 30, 2019) and we purchase reinsurance from financially strong reinsurers for which we already have an allowance for uncollectible reinsurance amounts, we do not expect that the effect of adoption will be material.

ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement

ASU 2018-13 modifies the disclosure requirements for assets and liabilities measured at fair value. The requirements to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements have all been removed. However, the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period must be disclosed along with the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements (or other quantitative information if it is more reasonable). Finally, for investments measured at net asset value, the requirements have been modified so that the timing of

liquidation and the date when restrictions from redemption might lapse are only disclosed if the investee has communicated the timing to the entity or announced the timing publicly.

This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. As the amendments are only disclosure related and we do not currently have any assets or liabilities that are measured based on Level 3 inputs, our financial statements will not be materially impacted by this update.

ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract

ASU 2018-15 requires a customer in a cloud computing arrangement (i.e. hosting arrangement) that is a service contract to follow the internal-use software guidance to determine which implementation costs to capitalize as assets or expense as incurred. Relevant implementation costs in the development stage are capitalized, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. Capitalized costs are expensed over the term of the hosting arrangement. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted. This update can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are currently evaluating how the adoption of this ASU will affect our financial statements.

INTANGIBLE ASSETS

E. INTANGIBLE ASSETS

Goodwill and intangible assets totaled $54.3 million and $54.5 million at June 30, 2019 and December 31, 2018, respectively, as detailed in the following table:

Goodwill and Intangible Assets		June 30,		December 31,
(in thousands)		2019		2018
Goodwill
Energy surety	$	25,706	$	25,706
Miscellaneous and contract surety		15,110		15,110
Small commercial		5,246		5,246
Total goodwill	$	46,062	$	46,062
Intangibles

Total intangibles	$	8,268	$	8,472
Total goodwill and intangibles	$	54,330	$	54,534

All definite-lived intangible assets are amortized against future operating results based on their estimated useful lives. Amortization of intangible assets was $0.1 million for the second quarter of 2019 and $0.2 million for the six-month period ended June 30, 2019, the same as for the comparable periods in 2018.

Annual impairment assessment was performed on our energy surety goodwill, miscellaneous and contract surety goodwill, small commercial goodwill and state insurance license indefinite-lived intangible asset during the second quarter of 2019. Based upon these reviews, none of the assets were impaired. In addition, as of June 30, 2019, there were no triggering events that would suggest an updated review was necessary on the above-mentioned goodwill and intangible assets.

Adverse loss experience triggered the need to test the medical professional liability reporting unit during the first quarter of 2018, which resulted in a $4.4 million non-cash impairment charge. A fair value for the medical professional liability reporting unit’s agency relationships, carried as a definite-lived intangible, was determined by using a discounted cash flow valuation. The carrying value exceeded the fair value, resulting in a $0.8 million non-cash impairment charge. A fair value for the medical professional liability reporting unit’s goodwill was determined by using a weighted average of a market approach and discounted cash flow valuation. The carrying value exceeded the fair value, resulting in a $3.6 million non-cash

impairment charge. Subsequent to the first quarter 2018 impairment, the medical professional liability reporting unit had no remaining goodwill or intangible assets. All impairment charges were recorded as net realized losses in the consolidated statement of earnings.

EARNINGS PER SHARE

F. EARNINGS PER SHARE

Basic earnings per share (EPS) excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock or common stock equivalents were exercised or converted into common stock. When inclusion of common stock equivalents increases the earnings per share or reduces the loss per share, the effect on earnings is anti-dilutive. Under these circumstances, the diluted net earnings or net loss per share is computed excluding the common stock equivalents. The following represents a reconciliation of the numerator and denominator of the basic and diluted EPS computations contained in the unaudited condensed consolidated interim financial statements:

	For the Three-Month Period					For the Three-Month Period

COMPREHENSIVE EARNINGS

G. COMPREHENSIVE EARNINGS

Our comprehensive earnings include net earnings plus after-tax unrealized gains and losses on our fixed income portfolio. In reporting other comprehensive earnings on a net basis in the statement of earnings, we used the federal statutory tax rate of 21 percent.

Unrealized gains, net of tax, on the fixed income portfolio for the first six months of 2019 were $57.2 million, compared to $34.1 million of unrealized losses, net of tax, during the same period last year. Unrealized gains in the first six months of 2019 were attributable to declining interest rates, which increased the fair value of securities held in the fixed income portfolio. In contrast, rising interest rates decreased the fair value of securities held in the fixed income portfolio in the first six months of 2018.

The following table illustrates the changes in the balance of each component of accumulated other comprehensive earnings for each period presented in the unaudited condensed consolidated interim financial statements:

(in thousands)	For the Three-Month Periods				For the Six-Month Periods
	Ended June 30,				Ended June 30,

Ending balance	$	42,593	$	(14,648)	$	42,593	$	(14,648)

In 2018, the adoption of accounting standards resulted in adjustments to accumulated other comprehensive earnings. ASU 2016-01 required equity investments to be measured at fair value with changes in fair value recognized in net earnings. A cumulative-effect adjustment was made as of the beginning of 2018, which moved $142.2 million of net unrealized gains and losses on equity securities from accumulated other comprehensive earnings to retained earnings.

ASU 2018-02 addressed issues arising from the enactment of the Tax Cuts and Jobs Act of 2017. Accounting guidance required deferred tax items to be revalued based on the new tax laws with the changes included in net earnings. Since other comprehensive earnings was not affected by the revaluation of the deferred tax items, the accumulated other comprehensive earnings balance was reflective of the historic tax rate instead of the newly enacted rate, which created a stranded tax effect. ASU 2018-02 allowed for the reclassification of our $3.7 million stranded tax effect out of accumulated other comprehensive earnings into retained earnings.

The sale or other-than-temporary impairment of an available-for-sale security results in amounts being reclassified from accumulated other comprehensive earnings to current period net earnings. The effects of reclassifications out of accumulated other comprehensive earnings by the respective line items of net earnings are presented in the following table:
