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 ~~September 30, 2020~~March 31, 2021 and the results of operations of RLI Corp. (the Company) 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 ~~2019~~2020 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.

~~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~~No new accounting standards applicable in 2021 impact our financial instruments. Previous guidance delayed the recognition of credit losses until it was probable a loss had been incurred. This update requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that is included in net earnings. Credit losses relating to available-for-sale debt securities are also required to be recorded through a reversible allowance for credit losses, but is limited to the amount by which fair value is less than amortized cost.

We adopted ASU 2016-13 on January 1, 2020 using the modified-retrospective approach. The standard applied to three of the Company’s balance sheet accounts: available-for-sale fixed income securities, premiums receivable and reinsurance balances recoverable. The impact of this standard was and is expected to continue to be immaterial, as our fixed income portfolio is weighted towards higher rated bonds (83 percent rated A or better at September 30, 2020 and 85 percent at December 31, 2019), we purchase reinsurance from financially strong reinsurers, we have a long history of collecting premium receivables through various economic cycles and we had previously maintained an allowance for uncollectible premium and reinsurance balances. In total, the cumulative-effect adjustment made to the balance sheet as of the beginning of the year resulted in a $1.1 million increase to retained earnings and an increase to accumulated other comprehensive earnings of less than $0.1 million.statements.

There are no prospective accounting standards which would have a material impact on our financial statements as of March 31, 2021.

Ceded unearned premiums and reinsurance balances recoverable on ~~paid and~~ unpaid losses and settlement expenses are reported separately as ~~assets, instead of~~an asset, rather than being netted with the related ~~liabilities,~~liability, since reinsurance does not relieve the Company of our ~~legal~~ liability to ~~our~~ policyholders. Such balances are subject to the credit risk associated with the individual reinsurer. We ~~continuously~~continually monitor the financial condition of our reinsurers and actively follow up on any past due or disputed amounts. As part of our monitoring efforts, we review their annual financial statements ~~quarterly disclosures~~ and Securities and Exchange Commission (SEC) filings for those reinsurers that are publicly traded. We also review insurance industry developments that may impact the financial condition of our reinsurers. We analyze the credit risk associated with our reinsurance balances recoverable by monitoring the AM Best and Standard & Poor’s (S&P) ratings of our reinsurers. In addition, we subject our reinsurance recoverables to detailed recoverability tests, including a segment-based analysis using the average default rating percentage by S&P rating, which assists the Company in assessing the sufficiency of the existing allowance. Additionally, we perform an in-depth reinsurer financial condition analysis prior to the renewal of our reinsurance placements.

~~Once regulatory action (such as receivership, finding of insolvency, order of conservation or order of liquidation)~~Our policy is ~~taken against a reinsurer, the paid and unpaid balances recoverable from the reinsurer are specifically identified and charged~~to charge to earnings, in the form of an allowance, for uncollectible amounts. We subject our remaining reinsurance balances receivable to detailed recoverability tests, including a segment-based analysis using the average default rating percentage by S&P rating, and record an ~~additional allowance for~~estimate of unrecoverable amounts from reinsurers. This ~~credit~~ allowance is reviewed on an ongoing basis to ensure that the amount makes a reasonable provision for reinsurance balances that we may be unable to recover.

insolvency, order of conservation or order of liquidation) is taken against a reinsurer, all paid and unpaid balances recoverable for the reinsurer are specifically identified and expensed into our allowance for estimated unrecoverable amounts from reinsurers. We then re-evaluate the remaining allowance and determine whether the balance is sufficient as detailed above and if needed, an additional allowance is recognized and income charged.

The allowances for uncollectible amounts on paid and unpaid reinsurance recoverables were $15.9 million and ~~$8.1~~$9.0 million, respectively, at ~~September 30, 2020.~~March 31, 2021. At December 31, ~~2019,~~2020, the amounts were ~~$15.7~~$15.9 million and ~~$9.4~~$8.6 million, respectively. ~~Adoption of ASU 2016-13 resulted in a $1.3 million decrease to the allowance for uncollectible amounts on reinsurance recoverables in 2020, while other changes~~Changes in the allowances were due to changes in the amount of reinsurance balances outstanding, the composition of reinsurers from whom the balances were recoverable and their associated S&P default ratings. NaN write-offs ~~or recoveries~~ were applied to the allowances in the first ~~nine~~three months of ~~2020.~~2021 and less than $0.1 million was recovered. We have 0 receivables with a due date that extends beyond one year that are not included in our allowance for uncollectible amounts.

The composition of goodwill and intangible assets at ~~September 30, 2020~~March 31, 2021 and December 31, ~~2019~~2020 is detailed in the following table:

All definite-lived intangible assets are amortized based on their estimated useful lives. Amortization of intangible assets was $0.1 million for the ~~third~~first quarter of ~~2020~~2021 and ~~$0.3 million for the nine months ended September 30, 2020, the same as for the comparable periods in 2019.~~2020.

Annual impairment assessments were performed on our goodwill and state insurance license indefinite-lived intangible asset during ~~the second quarter of~~ 2020. Based upon these reviews, NaN of the assets were impaired. In addition, there were no triggering events as of ~~September 30, 2020~~March 31, 2021 that would suggest an updated impairment test would be needed for our goodwill and intangible assets.

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~~these items 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.~~these items.

Our comprehensive earnings include net earnings plus after-tax unrealized gains and losses on our available-for-sale fixed income portfolio. In reporting ~~other~~the components of comprehensive earnings, ~~on a net basis,~~ we used the federal statutory tax rate of 21 percent. Other comprehensive earnings (loss), as shown in the consolidated statements of earnings and comprehensive earnings, is net of tax ~~expense~~benefit of ~~$2.5~~$11.9 million and ~~$4.1~~$3.5 million for the ~~third~~first quarter of ~~2020~~2021 and ~~2019, respectively. For the nine-month periods ended September 30,~~ 2020, ~~and 2019, other comprehensive earnings is net of tax expense of $13.3 million and $19.3 million,~~ respectively.

Unrealized ~~gains,~~losses, net of tax, ~~on the fixed income portfolio~~recognized in other comprehensive earnings (loss) were ~~$50.1~~$44.7 million for the first ~~nine~~three months of ~~2020,~~2021, compared to ~~$72.5~~$13.0 million during the same period last year.

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,~~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 are 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, pre-payment 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/CMBS and ABS are deemed Level 2.

Regulation D Private Placement Securities: All Regulation D ~~privately placed~~privately-placed bonds are classified as corporate securities and deemed Level 3. The pricing vendor evaluation methodology for these securities includes a combination of observable and unobservable inputs. Observable inputs include public corporate spread matrices classified by sector, rating and average life, as well as investment and non-investment grade matrices created from fixed income indices. Unobservable inputs include a liquidity spread premium calculated based on public corporate spread and private corporate spread matrices. The

quantitative detail of the liquidity spread premium is neither provided nor reasonably available to the Company. An increase to the credit spread assumptions would result in a lower fair ~~value measurement.~~value.

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. If discrepancies are found in our comparisons, 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 fixed income securities provided by our pricing services are reasonable.

Common Stock: As of ~~September 30, 2020,~~March 31, 2021, nearly all of our common stock holdings were 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 securities 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 investments’ net asset value per share and are not categorized within the fair value hierarchy.

Certain risks and uncertainties are inherent to our day-to-day operations. Adverse changes in the economy could lower demand for our insurance products or negatively impact our investment results, both of which could have an adverse effect on the revenue and profitability of our operations. The COVID-19 pandemic may continue to result in significant disruptions in economic activity and financial markets. The cumulative effects of any public health outbreak could reduce demand for our insurance policies, result in increased level of losses, settlement expenses or other operating costs, reduce the market value of invested assets held by the Company or negatively impact the fair value of our goodwill.

Our catastrophe reinsurance treaty renewed on January 1, 2020. We purchased limits of $400 million in excess of $25 million first-dollar retention for earthquakes in California, $425 million in excess of $25 million first-dollar retention for earthquakes outside of California and $275 million in excess of $25 million first-dollar retention for all other perils. These amounts are subject to certain co-participations by the Company on losses in excess of the $25 million retentions. On March 1, 2020, we purchased $100 million of additional catastrophe reinsurance protection on top of the previously described coverage. This increases the limits to $500 million for earthquakes in California, $525 million for earthquakes outside of California and $375 for all other perils, all of which are still subject to $25 million first-dollar retentions and certain co-participations in excess of the retentions.

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.

Realized gains and losses on disposition of investments are based on specific identification of the investments sold on the settlement date. The following is a summary of the disposition of fixed income and equity securities for the ~~nine-month~~three-month periods ended ~~September 30, 2020~~March 31, 2021 and ~~2019:~~2020:

We adopted ASU 2016-13, Financial Instruments – Credit Losses, on January 1, 2020, which required the recognition of a ~~reversible~~reversable allowance for credit losses on available-for-sale fixed income securities. ~~See note 1. B. for more information on the adoption of the ASU.~~ Available-for-sale securities in the fixed income portfolio are subjected to several criteria to determine if those securities should be included in the allowance for expected credit loss evaluation, including:

If changes in interest rates and credit spreads do not reasonably explain the unrealized loss for an available-for-sale security or if any of the criteria above indicate a potential credit loss, the security is subjected to a discounted cash flow analysis. Inputs into the discounted cash flow analysis include prepayment assumptions for structured securities, default rates and recoverability rates based on credit rating. The allowance for any security is limited to the amount that the securities fair value is below amortized cost. As of ~~September 30, 2020,~~March 31, 2021, the discounted cash flow analysis resulted in an allowance for credit losses on 2916 securities. The following table presents changes in the allowance for expected credit losses on available-for-sale securities:

Net realized gains included $0.6 million of losses on fixed income securities for which we no longer had the intent to hold until recovery and the cost basis was written down to fair value. All fixed income securities continue to pay the expected coupon payments. We believe we will recover the amortized cost basis of available-for-sale securities that remain in an unrealized loss position.

Prior to the adoption of ASU 2016-13, we conducted reviews of fixed income securities with unrealized losses to evaluate whether an impairment was other-than-temporary. Any credit-related impairment on fixed income securities we did not plan to sell and we were not more likely than not to be required to sell were recognized in net earnings, with the non-credit related impairment recognized in comprehensive earnings. We did not recognize any other-than-temporary impairment losses in earnings on the fixed income portfolio in the first nine months of 2019.

As of ~~September 30, 2020,~~March 31, 2021, in addition to the securities included in the allowance for credit losses, the fixed income portfolio contained ~~234~~320 securities with an unrealized loss position for which an allowance for credit losses had not been recorded. The ~~$4.6~~$15.0 million in associated unrealized losses represents ~~0.2~~0.7 percent of the fixed income portfolio’s cost basis and ~~0.2~~0.5 percent of total invested assets. Isolated to these securities, unrealized losses increased through the first ~~nine~~three months of ~~2020,~~2021, as ~~increased credit spreads more than offset declines in~~ interest rates increased during the ~~period, primarily in the corporate portfolio.~~period. Of the total ~~263~~320 securities, 2932 have been in an unrealized loss position for 12 consecutive months or longer. The following table illustrates the total value of fixed income securities that were in an unrealized loss position as of ~~September 30,~~March 31, 2021 and December 31, 2020 after factoring in the allowance for credit ~~losses,~~losses. All fixed income securities continue to pay the expected coupon payments and ~~December 31, 2019.~~we believe we will recover the amortized cost basis of available-for-sale securities that remain in an unrealized loss position.

Unrealized gains recognized on equity securities still held as of ~~September 30, 2020~~March 31, 2021 were ~~$28.7 million during the third quarter, while unrealized losses were $14.1~~$41.2 million during the first ~~nine months of 2020.~~quarter. Comparatively, unrealized ~~gains~~losses recognized on equity securities still held as of ~~September 30, 2019~~March 31, 2020 were ~~$6.9 million during the third quarter and $61.7~~$115.2 million during the first ~~nine months of 2019.~~quarter.

We had ~~$60.0~~$50.4 million of other invested assets at ~~September 30, 2020,~~March 31, 2021, compared to ~~$70.4~~$54.2 million at ~~the end of 2019.~~December 31, 2020. 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 and investments in restricted stock.~~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. ~~Restricted stock is carried at quoted market prices, as the restrictions expire within one year.~~

Our LIHTC interests had a balance of ~~$21.0~~$19.4 million at ~~September 30, 2020,~~March 31, 2021, compared to ~~$23.3~~$20.3 million at December 31, ~~2019~~2020 and recognized a total tax benefit of $0.9 million during the ~~third quarter~~first quarters of ~~2020, compared to $0.6 million in the prior year. For the nine-month periods ended September 30, 2020~~2021 and ~~2019, our LIHTC interest recognized a total benefit of $2.6 million and $1.9 million, respectively.~~2020. Our unfunded commitment for our LIHTC investments totaled ~~$4.7~~$2.7 million at ~~September 30, 2020~~March 31, 2021 and will be paid out in installments through 2035.

As of ~~September 30, 2020, $13.7~~March 31, 2021, $10.2 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 ~~nine-month~~three-month period ended ~~September 30, 2020,~~March 31, 2021, there were 0 outstanding borrowings with the FHLBC.

Our investments in private funds totaled ~~$26.5~~$27.8 million at ~~September 30, 2020,~~March 31, 2021, compared to ~~$46.0~~$32.1 million at December 31, ~~2019,~~2020, and we had ~~$8.3~~$6.5 million of associated unfunded commitments at ~~September 30, 2020.~~March 31, 2021. Our interest in private funds is generally restricted from being transferred or otherwise redeemed without prior consent by the respective entities. During the first quarter of 2020, one of the private funds transitioned into a publicly traded common stock. Short-term restrictions, limiting our ability to sell without prior approval, were establishedentities and ~~remain in place. Our investment in restricted stock was $10.6 million as of September 30, 2020. For our remaining investments in private funds,~~ the timed dissolution of the partnerships would trigger redemption. At December 31, 2020, we had a publicly traded common stock with short-term restrictions that limited our ability to sell the security without prior approval. During the first quarter of 2021, our investment in this security became unrestricted and the investment was included in our equity portfolio as of March 31, 2021.

Cash consists of uninvested balances in bank accounts. We had a cash balance of ~~$70.6~~$94.9 million at ~~September 30, 2020,~~March 31, 2021, compared to ~~$46.2~~$62.2 million at ~~the end of 2019.~~December 31, 2020.

We adopted ASU 2016-13, Financial Instruments – Credit Losses, on January 1, 2020, which required financial assets, including reinsurance balances recoverable, to be presented at the net amount expected to be collected. We previously maintained an allowance for uncollectible reinsurance balances prior to the adoption of this update. However, in order to comply with the updated requirements, we released $1.3 million of the allowance on uncollectible reinsurance balances upon adoption. The implementation guidance required the cumulative-effect adjustment be made to the beginning balance of retained earnings, rather than through net earnings like historical changes have and ongoing modifications will continue to be recorded. ~~See note 1. B. for more information on the adoption of the ASU.~~

For the first ~~nine~~three months of 2021, incurred losses and LAE included $37.1 million of favorable development on prior years’ loss reserves. General liability, transportation, small commercial, professional services, personal umbrella and surety were drivers of the favorable development. No products experienced significant adverse development.

For the first three months of 2020, incurred losses and LAE included ~~$70.0~~$15.2 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, executive products,~~ marine, small commercial and surety. No products experienced significant ~~adverse development.~~

For the first nine months of 2019, incurred losses and LAE included $55.2 million of favorable development on prior years’ loss reserves. Transportation, general liability, commercial excess and personal umbrella, professional services, small commercial and surety were drivers of the favorable development. Executive products experienced adverse development.

Actuarial models base future emergence on historic experience, with adjustments for current trends, and the appropriateness of these assumptions involved more uncertainty as of ~~September 30, 2020.~~March 31, 2021. We expect there will be impacts to the timing of loss emergence and ultimate loss ratios for certain coverages we underwrite as a result of the spread of COVID-19 and the related economic shutdown. The industry is experiencing new issues, including the postponement of civil court cases, the extension of various statutes of limitations, changes in settlement trends and a significant reduction in economic activity and insured exposure in some classes. Our ~~booked~~recorded reserves include consideration of these factors, but the duration and degree to which these issues persist, along with potential legislative, regulatory or judicial actions, could result in loss reserve deficiencies and reduce earnings in future periods.

Our effective tax rate for the three ~~and nine~~ months ended ~~September 30, 2020~~March 31, 2021 was ~~17.7~~18.7 percent, ~~and 15.8 percent, respectively,~~ compared to ~~17.0~~22.8 percent ~~and 18.4 percent, respectively,~~ for the same ~~periods~~period in ~~2019.~~2020. Effective rates are dependent upon components of pretax earnings and the related tax effects. The effective rate was lower for the ~~nine-month period in 2020 due to investment tax credits recognized using the flow-through method~~first three months of ~~accounting, whereby income taxes payable and~~2021 as tax-favored adjustments reduced income tax expense, ~~were reduced. Additionally, lower levels~~while tax-favored adjustments increased the tax benefit recognized in the first quarter of 2020 as a result of pretax earnings caused tax-favored adjustments to be larger on a percentage basis in 2020 compared to the prior year. For the three-month period, a higher level of pretax earnings in 2020 resulted in a higher effective tax rate.losses.

Income tax expense attributable to income from operations for the ~~three and nine-month~~three-month periods ended ~~September 30,~~March 31, 2021 and 2020 ~~and 2019~~ 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, net line.

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 ~~awarded 2,576,867 stock options and restricted stock units~~granted 2,667,865 awards under the 2015 ~~LTIP.~~LTIP, including 44,496 thus far in 2021.

Compensation expense is based on the probable number of awards expected to vest. The total compensation expense related to equity awards was $1.6 million and $1.3 million in the first three months of 2021 and 2020, respectively, and the total income tax benefit was $0.3 million and $0.2 million for each period, respectively. Total unrecognized compensation expense relating to outstanding and unvested awards was $5.4 million, which will be recognized over the weighted average vesting period of 2.56 years.

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.

~~Through 2019,~~The intrinsic value, which is the ~~majority of our annual stock option grants were authorized at our regular board meeting in May. In addition, quarterly grants to certain retirement eligible employees were historically authorized at~~difference between the ~~May meeting. Since stock option grants to retirement eligible employees are fully expensed when issued,~~fair value and the approach allowed for a more even expense distribution throughout the year. In 2020, the annual stock option grants and quarterly grants to retirement eligible employees were authorized at the August board meeting to allow the Company additional time to assess the financial impact of the COVID-19 pandemic.

~~In the first nine months of 2020, 275,977 stock options were granted with a weighted average~~ exercise price, of ~~$93.39~~options exercised was $6.9 million and ~~a weighted average fair value of $13.33. We recognized $1.3~~$2.5 million ~~of expense in~~during the ~~third~~first quarter of 2021 and 2020, and $2.8 million in the first nine months of 2020 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 third quarter of 2020 and $0.6 million in the first nine months of 2020 related to this compensation expense. Total unrecognized compensation expense relating to outstanding and unvested options was $5.6 million, which will be recognized over the remainder of the vesting period. Comparatively, we recognized $1.2 million of compensation expense in the third quarter of 2019 and $3.6 million in the first nine months of 2019. We recorded a tax benefit of $0.2 million in the third quarter of 2019 and $0.7 million in the first nine months of 2019 related to this compensation expense.respectively.

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 ~~September 30:~~March 31:

	2020			2019			2021			2020
Weighted-average fair value of grants	$	13.33		$	13.47		$	13.82		$	14.48
Risk-free interest rates		0.41	%		2.41	%		0.27	%		1.54	%
Dividend yield		2.30	%		2.69	%		2.30	%		2.69	%
Expected volatility		22.67	%		22.71	%		22.67	%		22.68	%
Expected option life		4.96	years		4.95	years		4.96	years		4.99	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.

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. ~~These~~For employees, these units generally have a three-year cliff vesting, but have an accelerated vesting feature for participants who are retirement eligible, defined by the plan as those individuals whose age and years of service equals 75. For directors, these units vest on the earlier of one year from the date of grant or the next annual shareholders meeting. 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. RSUs are generally granted at our regular board meeting in May, but were granted at the August board meeting in 2020 to allow the Company additional time to assess the financial impact of the COVID-19 pandemic.

As of September 30, 2020, 58,420 RSUs have been granted to employees under the 2015 LTIP and 41,826 remain outstanding. We recognized $0.2 million of expense on these units in the third quarter of 2020 and $0.5 million in the first nine months of 2020. Total unrecognized compensation expense relating to outstanding and unvested RSUs was $1.6 million, which will be recognized over the remainder of the vesting period. Comparatively, we recognized $0.3 million in the third quarter of 2019 and $0.6 million in the first nine months of 2019.

In 2020 and 2019, each outside director was granted a whole number of RSUs with a fair market value corresponding to $50,000 on the date of grant as part of annual director compensation. Director RSUs vest on the earlier of one year from the date of grant or the next annual shareholders meeting. As of September 30, 2020, 20,445 restricted stock units have been granted to directors under the 2015 LTIP and 5,375 remain outstanding. We recognized $0.1 million of compensation expense on these units in the third quarter of 2020 and $0.2 million in the first nine months of 2020. Comparatively, we recognized $0.1 million of compensation expense on these units in the third quarter of 2019 and $0.5 million in the first nine months of 2019.

Right-of-use (ROU) 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 ROU 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. Operating lease cost for future minimum lease payments is recognized on a straight-line basis over the lease term. Variable lease cost is expensed in the period in which the obligation is incurred. Sublease income is recognized on a straight-line basis over the sublease term.

The Company’s operating lease obligations are for branch office facilities. The components of lease expense and other lease information as of and during the ~~three and nine-month~~three-month periods ended ~~September 30,~~March 31, 2021 and 2020 ~~and 2019~~ are as follows:

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 appear throughout this report. These statements relate to our current expectations, beliefs, intentions, goals or strategies regarding the future and are based on certain underlying assumptions by the Company. These forward looking statements generally include words such as “expect,” “predict,” “estimate,” “will,” “should,” “anticipate,” “believe” and similar expressions. Such assumptions are, in turn, based on information available and internal estimates and analyses of general economic conditions, competitive factors, conditions specific to the property and casualty insurance and reinsurance industries, claims development and the impact thereof on our loss reserves, the adequacy and financial security of our reinsurance programs, developments in the securities market and the impact on our investment portfolio, regulatory changes and conditions and other factors. These assumptions are subject to various risks, uncertainties and other factors, including, without limitation those set forth in “Item 1A. Risk Factors” within the Annual Report on Form 10-K for the year ended December 31, ~~2019~~2020 and Part II within this report. Actual results could differ materially from those expressed in, or implied by, these forward looking statements. We assume no obligation to update any such statements. You should review the various risks, uncertainties and other factors listed from time to time in our Securities and Exchange Commission filings.

RLI Corp. is a U.S.-based, specialty insurance company that underwrites select property and casualty insurance through major subsidiaries collectively known as RLI Insurance Group (Group). Our focus is on niche markets and developing unique products that are tailored to customers’ needs. We hire underwriters and claim examiners with deep expertise and provide exceptional customer service and support. We maintain a highly diverse product portfolio and underwrite for profit in all market conditions. In ~~2019,~~2020, we achieved our ~~24th~~25th consecutive year of underwriting profitability. Over the ~~24-year~~25-year period, we averaged an 88.3 combined ratio. 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.

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, pandemics 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.

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 assume a limited amount of hard-to-place risks through a quota share reinsurance agreement. 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.

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, hurricanes and other storms. 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 ~~seek to~~ limit our net aggregate exposure to a catastrophic event by minimizing the total policy limits written in a particular region, purchasing reinsurance and maintaining ~~consistent~~ policy terms and conditions throughout insurance cycles. We also use computer-assisted modeling techniques to provide estimates that help the Company 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, including payment and performance bonds. 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. However, 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.

Throughout this quarterly report, we include certain non-generally accepted accounting principles (non-GAAP) financial measures. Management believes that these non-GAAP measures further 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.

The 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 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 in note 6 to the unaudited condensed consolidated interim financial statements in this quarterly report on Form 10-Q, and in note 12 to the consolidated financial statements in our ~~2019~~2020 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 gains or losses on equity securities, general corporate expenses, debt costs and our portion of earnings from unconsolidated investees. A reconciliation of net earnings to underwriting income follows:

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.

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, recoverability of reinsurance balances, deferred policy acquisition costs and deferred taxes. For a detailed discussion of each of these policies, refer to our ~~2019~~2020 Annual Report on Form 10-K.

We adopted ASU 2016-13, Financial Instruments – Credit Losses, on January 1, 2020, which eliminated the concept of other-than-temporary impairment and required the recognition of a reversible allowance for credit losses on available-for-sale fixed income securities. See note 1. B. for more information on the adoption of the ASU. Available-for-sale securities in the fixed income portfolio are subjected to several criteria to determine if those securities should be included in the allowance for expected credit loss evaluation, including:

If changes in interest rates and credit spreads do not reasonably explain the unrealized loss for an available-for-sale security or if any of the criteria above indicate a potential credit loss, the security is subjected to a discounted cash flow analysis. Inputs into the discounted cash flow analysis include prepayment assumptions for structured securities, default rates and recoverability rates based on credit rating. The allowance for any security is limited to the amount that the securities fair value is below amortized cost. If we intend to sell a security or if we determine it is more likely than not that we will be required to sell a security before recovery of its amortized cost basis, any allowance for credit loss or unrealized loss would be written off and the amortized cost basis of the security would be written down to the security’s fair value.

There have been no ~~other~~ significant changes to critical accounting policies during the year.

~~The coronavirus (COVID-19) pandemic continues to impact individuals, businesses and the economy.~~ As an employee-owned company, the health and well-being of our customers, partners and associates is our highest priority. While a large percentage of our associates are still working from home, our processes and controls continue to operate effectively and we have been able to maintain the highest service and support levels possible for our customers.

It is difficult to predict how and to what extent COVID-19, and its effects on the ~~economic slowdown~~economy, will ~~have on~~impact our revenues in the coming ~~months.~~quarters. To date, the product line that has experienced the greatest impact has been public transportation. Many of our passenger transportation customers have been unable to effectively operate under social-distancing protocols and stay-at-home orders. ~~For the nine-month period ended September 30, 2020, transportation gross written~~Transportation premium was down ~~$35.9 million when compared to 2019.

Additionally, slowdowns in the construction industry contributed to premium declines for our general liability, commercial umbrella and contract surety products. A number of our products support the construction industry, and revenues may continue to be impacted as long as this sector experiences disruption. However, ~~we have many product lines that may see little to no impact on the amount of premium we write, including~~ our personal lines products, management liability products and property ~~businesses.~~

The loss exposure arising out of the spread of COVID-19 and resulting shutdown will take time to resolve. We do not offer event cancellation, travel, trade credit or pandemic-related coverages, which would be more directly impacted by the COVID-19 pandemic. The Company has received a number of claims, the majority of which relate to business interruption. We are reviewing the individual circumstances of each claim submitted and will fulfill our obligation to pay if coverage applies. The derivative implications that COVID-19 has on the economy may have negative implications on products that are correlated with the credit cycle, including, but not limited to, some of our executive products and surety offerings. InAdditionally, the ~~third quarter of 2020, $4.1 million of net reserves were established~~professional services and executive product groups may be affected by claims made against companies who are reopening or returning to address the increased risk of loss and expense that emanated from the economic downturn brought on by the pandemic.

Actuarial models base future emergence on historic experience, with adjustments for current trends, and the appropriateness of these assumptions involved greater uncertainty as of ~~September 30, 2020.~~March 31, 2021. We expect there will be impacts to the timing of loss emergence and ultimate loss ratios for certain coverages. The industry is experiencing new issues, including the postponement of civil court cases, the extension of various statutes of limitations, changes in settlement trends and a significant reduction in economic activity and insured exposure in some classes. Our booked reserves include

consideration of these factors, but the duration and degree to which these issues persist, along with potential legislative, regulatory or judicial actions, could result in loss reserve deficiencies and reduce earnings in future periods.

~~We continue to evaluate opportunities for expense savings~~Investment yields decreased throughout 2020, which resulted in lower reinvestment rates and, efficiencies and have taken targeted actions to reduce or defer expenses, including certain hiring freezes, position consolidations, limiting travel and executive merit increase suspensions. Bonus and profit-sharing expense is correlated with company performance and is responsible for the largest portion of the total expense decline for the nine-month period ended September 30, 2020, compared to 2019. The performance-related expenses recognized for the 2020 fiscal year will be dependent on the full year’s results and may increase or decrease during the rest of the year.

~~The equity portfolio has nearly recovered from the sharp market sell off~~in turn, lower investment income in the first ~~quarter. Net after-tax realized and unrealized losses on equity securities were $11.2 million in the first nine months~~quarter of ~~2020. Conversely, lower interest rates increased~~2021. Additionally, the fair value of the fixed income portfolio ~~which resulted in $48.7~~will decline as interest rates rise, as was observed with our $44.7 million of after-tax other comprehensive earnings for the nine-month period ended September 30, 2020. With the decline in yields, reinvestment rates are now lower than in previous years, which will cap the portfolio’s ability to generate higher levels of investment income, absent a larger invested asset base.

~~Maui Jim, Inc. (Maui Jim) and Prime Holdings Insurance Services, Inc. (Prime) contributed towards positive net earnings in~~loss during the first nine months of 2020. While earnings for Prime were higher than in 2019, Maui Jim’s sales were negatively impacted by the shutdown much of the traditional retail sector experienced during the year.

We generated ~~$163.2~~$60.3 million of net operating cash inflows and believe we have ~~adequate liquidity.~~sufficient sources of liquidity to meet our anticipated needs over the next 12 to 24 months. Our revolving credit facility provides for a borrowing capacity of $60.0 million, which can be increased to $120.0 million under certain circumstances. Additionally, our membership in the Federal Home Loan Bank system provides a secured lending facility with an aggregate borrowing capacity of approximately $30.0 million. There were no amounts outstanding under any of these facilities as of September 30, 2020. In addition to the $157.6 million of cash and other investments maturing within one year as of September 30, 2020, we believe that cash generated from operations, the liquidity of our fixed income portfolio and our unused lines of credit provide sufficient sources of cash to meet our anticipated needs over the next 12 to 24 months.

Ultimately, the extent to which COVID-19 will impact our business will be influenced by how long it takes for the economy to recover. We continue to evaluate all aspects of our operations and are making necessary adjustments to manage our business. Our diversified portfolio of products and financial strength have allowed us to remain on solid footing. We believe we have a strong and sustainable underwriting approach that will allow us to weather the economic ~~downturn~~environment and uncertainty we are currently experiencing.

Underwriting income for the Group totaled $42.6 million for the nine months of 2020, compared to $51.1 million in the same period of 2019. Both periods reflect favorable reserve development on prior accident years, with 2020 experiencing a larger benefit. The combined ratio for the Group totaled 93.4 in the first nine months of 2020, compared to 91.8 in the same period of 2019. The loss ratio increased to 53.0 from 49.3, primarily due to the addition of $37.0 million in hurricane losses and $14.9 million of COVID-19 loss and claim defense costs. The Group’s expense ratio decreased to 40.4 from 42.5, as 2019 experienced stronger growth in book value and a lower combined ratio, which led to larger levels of bonus and profit-sharing expenses.Income

The segment’s loss ratio was ~~59.3~~47.2 in 2021, down from 65.7 in 2020 ~~down from 59.5~~as a result of improvements in ~~2019.~~the current accident year loss ratio, the increased level of favorable development and the addition of $3.0 million of reserves in 2020 related to COVID-19 investigative and defense costs. The expense ratio for the casualty segment was ~~35.4, down~~36.1, up from ~~37.0~~35.2 for the same period last ~~year, as reduced levels of bonus and profit-sharing expenses were incurred.~~year.

The property segment recorded underwriting loss of ~~$3.9~~$1.0 million for the first ~~nine~~three months of ~~2020,~~2021, compared to ~~$14.0~~$9.9 million of underwriting income for the same period last year. Underwriting results for 2021 included $6.1 million of favorable development on prior years’ loss and catastrophe reserves across most products and $14.9 million of winter storm losses. Comparatively, the 2020 underwriting results included ~~$9.5~~$4.8 million of favorable development on prior years’ loss and catastrophe reserves, primarily from the marine business, ~~$5.3~~$0.5 million of storm ~~and civil unrest~~ losses and the addition of $2.0 million of reserves related to COVID-19 investigative and defense costs. Hurricanes Hanna, Isaias, Laura and Sally resulted in $33.4 million of losses and $2.0 million of ceded reinstatement premium. Comparatively, the 2019 underwriting results included $3.8 million of favorable development on prior years’ loss and catastrophe reserves and $7.6 million of storm losses.

Underwriting results for the first ~~nine~~three months of ~~2020~~2021 translated into a combined ratio of ~~102.9,~~101.9, compared to ~~88.3~~77.7 for the same period last year. The segment’s loss ratio was ~~62.5~~61.3 in ~~2020,~~2021, up from ~~44.0~~36.0 in ~~2019~~2020 due to higher levels of ~~catastrophe~~storm losses. The segment’s expense ratio decreased to ~~40.4~~40.6 in ~~2020~~2021 from ~~44.3~~41.7 in the prior year, as increased levels of earned premium allowed the segment to better leverage expenses.

The surety segment recorded underwriting income of ~~$24.0~~$6.1 million for the first ~~nine~~three months of ~~2020,~~2021, compared to ~~$22.4~~$8.7 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 ~~2020~~2021 included favorable development on prior

accident years’ reserves, which decreased loss and settlement expenses for the segment by ~~$11.1 million, and offset $2.6 million in current year reserves established for COVID-19 related losses.~~$2.8 million. Comparatively, ~~2019~~2020 results included favorable development on prior accident years’ loss reserves, which decreased the segment’s loss and settlement expenses by ~~$8.1~~$4.0 million.

The combined ratio for the surety segment totaled ~~71.5~~78.5 for the first ~~nine~~three months of ~~2020,~~2021, compared to ~~74.4~~68.9 for the same period in ~~2019.~~2020. The segment’s loss ratio was ~~6.5~~10.7 in 2021, up from 2.8 in 2020 ~~down from 8.1 in 2019.~~due to lower reserve releases and modestly higher current accident year losses. The expense ratio was ~~65.0, down~~67.8, up from ~~66.3~~66.1 in the prior year.

Our investment portfolio generated net investment income of ~~$51.2~~$16.4 million during the first ~~nine~~three months of ~~2020, an increase~~2021, a decrease of ~~0.3~~7.6 percent from that reported for the same period in ~~2019.~~2020.

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

The fixed income portfolio ~~increased~~decreased by ~~$176.7~~$20.8 million in the first ~~nine~~three months of ~~2020.~~2021. The ~~increase~~decrease was due to ~~cash flows being allocated to~~ the ~~fixed income portfolio, as well as the decline~~increase in interest rates during the first ~~nine months of the year, lifting~~quarter, decreasing the fair value of securities in the fixed income portfolio. Average fixed income duration was ~~4.5~~4.8 years at ~~September 30, 2020,~~March 31, 2021, reflecting our current liability structure and sound capital position. The equity portfolio ~~decreased~~increased by ~~$4.7~~$31.2 million during the first ~~nine~~three months of ~~2020, nearly recovering from the sharp equity~~2021, reflecting strong market ~~sell off in the first quarter.~~returns.

Our effective tax rate for the first ~~nine~~three months of ~~2020~~2021 was ~~15.8~~18.7 percent, compared to ~~18.4~~22.8 percent for the same period in ~~2019.~~2020. Effective rates are dependent upon components of pretax earnings or losses and the related tax effects. The effective rate was lower for the first ~~nine~~three months of ~~2020,~~2021 as ~~investment tax credits were recognized and lower levels of pretax earnings resulted in larger~~ tax-favored adjustments ~~on a percentage basis when compared to~~reduced income tax expense, while tax-favored adjustments increased the ~~prior year.~~

~~Three Months Ended September 30, 2020 Compared to Three Months Ended September 30, 2019~~

~~Consolidated revenue for the third quarter of 2020 increased $25.9 million from the third quarter of 2019. Continued strong performance~~tax benefit recognized in the ~~equity market resulted in $28.1 million of unrealized gains on equity securities in the third~~first quarter of 2020, compared to $4.9 million of unrealized gains in the third quarter of 2019. Net premiums earned for the Group increased 3 percent, driven by growth from our property and casualty segments, which offset declines in our surety segment. Investment income decreased 6 percent due to lower average yields relative to the prior year. Realized gains during the quarter were $1.5

million and were comprised of $0.6 million of realized gains on equity securities from rebalancing our portfolio, $0.7 million of realized gains on the fixed income portfolio and $0.2 million of other realized gains. This compares to realized gains of $3.2 million in the third quarter of 2019, which were comprised of $2.1 million of realized gains on the equity portfolio and $1.1 million of realized gains on the fixed income portfolio.

Net earnings for the third quarter of 2020 totaled $42.4 million, compared to $32.3 million for the same period in 2019. The increase in earnings for 2020 was primarily attributed to $22.2 million of net after-tax unrealized gains on equity securities, compared to $3.9 million in 2019. Underwriting results for 2020 were impacted by more significant catastrophe activity, including $37.0 million of pretax losses from hurricanes Hanna, Isaias, Laura and Sally, and $4.1 million of COVID-19 related losses. Comparatively, pretax storm losses were $3.0 million in the third quarter of 2019. Results for each period benefited, however, from favorable development on prior years’ loss reserves, which provided additional pretax earnings of $29.2 million in the third quarter of 2020, compared to $14.4 million in 2019. The pretax bonus and profit sharing-related impact associated with prior years’ reserve development and catastrophe losses resulted in an expense reduction of $1.5 million in 2020, compared to an increase in expense of $1.7 million in 2019. 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.

During the third quarter of 2020, equity in earnings of unconsolidated investees totaled $8.7 million, including $6.2 million from Maui Jim and $3.3 million from Prime. Comparatively, the third quarter of 2019 reflected $4.0 million of earnings, including $2.8 million from Maui Jim and $1.2 million from Prime.

Comprehensive earnings totaled $51.9 million for the third quarter of 2020, compared to $47.7 million for the third quarter of 2019. Other comprehensive earnings primarily included after-tax unrealized gains and losses from the fixed income portfolio. The third quarter’s $9.6 million of other comprehensive earnings was due to declines in interest rates, which increased the market value of the portfolio. This compares to $15.3 million of other comprehensive earnings for the same period in 2019.

Gross premiums written for the Group increased $25.9 million for the third quarter of 2020, compared to the same period of 2019. Rate increases across the property and casualty portfolios were the largest influence on growth. Net premiums earned increased $5.4 million, also driven by products in the property and casualty segments.

Gross premiums written for the casualty segment were up $20.6 million in the third quarter of 2020. Premiums from commercial excess and personal umbrella increased $17.6 million, due to an expanded distribution base in personal umbrella and rate increases. Rate increases led to a 14 percent increase for our executive products group.

Transportation continues to be significantly affected by the stay-at-home orders associated with COVID-19. This is particularly impactful on our public transportation book that has a focus on charter or city buses, which stopped running to a large degree in March. A slowdown or suspension of construction activity in certain parts of the country and the continuing highly competitive market conditions also led to the decline in general liability.

Gross premiums written for the property segment totaled $68.5 million for the third quarter of 2020, up $5.1 million from the same period last year. Our commercial property business was up $4.6 million due to rate increases on wind-prone and earthquake exposures, which continued at a greater pace than in prior years. Market disruption created new business opportunities and led to $0.4 million of growth for our marine product. Other property premium increased as a result of property-exposed GBA business that continues to gain scale.

The surety segment recorded gross premiums written of $30.3 million for the third quarter of 2020, an increase of $0.2 million from the same period last year. Growth in commercial surety and refocused sales efforts in our miscellaneous surety line outpaced the effects of the economic downturn in the third quarter and offset declines from contract surety.

Underwriting income for the Group totaled $1.2 million for the third quarter of 2020, compared to $13.7 million in the same period last year. Both periods reflect favorable reserve development on prior accident years, with 2020 experiencing a larger benefit. The combined ratio for the Group totaled 99.5 in the third quarter of 2020, compared to 93.5 in the same period of 2019. The loss ratio increased to 58.9 from 51.6, due to the hurricane losses incurred in 2020. The Group’s expense ratio

decreased to 40.6 from 41.9, as 2019 experienced stronger earnings and growth in book value in the nine-month period ended September 30, which led to larger levels of bonus and profit-sharing expenses.

The casualty segment recorded underwriting income of $14.0 million in the third quarter of 2020, compared to $2.4 million for the same period last year. Reserve releases reduced loss and settlement expenses for the casualty segment by $22.0 million, primarily on accident years 2017 through 2019. Transportation, general liability, commercial excess, executive products and professional services were drivers of the favorable development. Partially offsetting these benefits in the third quarter of 2020, $3.6 million of hurricane losses were recorded on casualty-oriented package polices that include property coverage and $2.6 million of reserves were established for COVID-19 related loss and defense costs. In comparison, $12.4 million of reserves were released in the third quarter of 2019, with transportation, professional services, commercial excess, general liability and small commercial making notable contributions to the favorable development.

~~The combined ratio for the casualty segment was 90.2 in 2020, compared to 98.3 in 2019. The segment’s loss ratio was 54.6 in 2020, down from 61.7 in 2019. The loss ratio decreased in~~ 2020 as a result of more favorable development on prior years’ reserves. The expense ratio for the casualty segment was 35.6, down from 36.6 for the same period last year, as reduced levels of bonus and profit-sharing expenses were incurred.

The property segment recorded underwriting loss of $20.0 million for the third quarter of 2020, compared to $6.2 million of underwriting income for the same period last year. Underwriting results for 2020 included $33.4 million of losses and $2.0 million of ceded reinstatement premium from Hurricanes Hanna, Isaias, Laura and Sally, as well as $4.0 million of favorable development on prior years’ loss and catastrophe reserves. Comparatively, the 2019 underwriting results included $3.0 million of storm losses and $1.8 million of favorable development on prior years’ loss and catastrophe reserves.

Underwriting results for the third quarter of 2020 translated into a combined ratio of 144.0, compared to 85.0 for the same period last year. The segment’s loss ratio was 103.3 in 2020, up from 42.0 in 2019 due to hurricanepretax losses. The segment’s expense ratio decreased to 40.7 in 2020 from 43.0 in the prior year, as increased levels of earned premium allowed the segment to better leverage expenses and reduced levels of bonus and profit-sharing expenses were incurred.

The surety segment recorded underwriting income of $7.1 million for the third quarter of 2020, compared to $5.2 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 2020 and 2019 included favorable development on prior accident years’ loss reserves, which decreased the segment’s loss and settlement expenses by $3.2 million and $0.1 million, respectively. Additionally, $1.5 million of reserves were established in 2020 for COVID-19 related losses.

The combined ratio for the surety segment totaled 74.8 for the third quarter of 2020, compared to 82.4 for the same period in 2019. The segment’s loss ratio was 9.4 in 2020, down from 17.0 in 2019 due to larger reserve releases. The expense ratio was 65.4 in 2020 and 2019.

Our investment portfolio generated net investment income of $16.5 million during the third quarter of 2020, a decrease of 5.6 percent from that reported for the same period in 2019. The decrease in investment income was largely due to a decline in yields relative to the prior year.

~~Yields on our fixed income investments for the third quarter of 2020 and 2019 were as follows:~~

Our effective tax rate for the third quarter of 2020 was 17.7 percent, compared to 17.0 percent for the same period in 2019. Effective rates are dependent upon components of pretax earnings or losses and the related tax effects. The effective rate was higher for the third quarter of 2020 due to higher levels of pretax earnings compared to 2019.

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 ~~nine-month~~three-month periods ended ~~September 30, 2020~~March 31, 2021 and ~~2019:~~2020:

(in thousands)	2020			2019			2021			2020
Operating cash flows	$	163,244		$	186,762		$	60,287		$	(5,767	)
Investing cash flows		(114,707	)		(134,862	)		(16,544	)		10,048

Total	$	24,386		$	33,908		$	32,718		$	(3,502	)

Our largest source of cash is premiums received from customers and our largest cash outflow is claim payments on insured losses. Cash flows from operating activities can vary among periods due to the timing in which these payments are

made or received. Operating cash flows in the first ~~nine~~three months of ~~2020 were impacted by increased~~2021 benefited from lower levels of loss and settlement expense payments and increase premium receipts relative to the first ~~nine~~three months of 2019. Additionally, improved financial performance in 2019 resulted in a higher level of bonus and profit-sharing contributions that were paid in the first quarter of 2020, which also reduced operating cash flows in 2020.

We have ~~$149.4~~$149.5 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 notes at ~~September 30, 2020~~March 31, 2021 was ~~$163.9~~$164.4 million. The fair value of our debt is estimated based on the limited observable prices that reflect thinly traded securities.

As of ~~September 30, 2020,~~March 31, 2021, we had cash and other investments maturing within one year of approximately ~~$157.6~~$201.8 million and an additional ~~$556.0~~$572.0 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 Bank of Montreal, Chicago Branch, which permits us to borrow up to an aggregate principal amount of $60.0 million. This facility was entered into during the first quarter of 2020 and replaced the previous $50.0 million facility with JP Morgan Chase Bank N.A., which was set to expire on May 24, 2020. Under certain

conditions, the line may be increased up to an aggregate principal amount of $120.0 million. The facility has a three-year term that expires on March 27, 2023. As of and during the ~~nine-month~~three-month period ended ~~September 30, 2020,~~March 31, 2021, no amounts were outstanding on either facility.

Additionally, two of our insurance companies, RLI Insurance Company (RLI Ins.) and Mt. Hawley Insurance Company, 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 ~~nine-month~~three-month period ended ~~September 30, 2020,~~March 31, 2021, 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.

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. Invested assets at ~~September 30, 2020~~March 31, 2021 have increased ~~$186.0~~$39.3 million from December 31, ~~2019.~~2020. As of ~~September 30, 2020,~~March 31, 2021, our investment portfolio had the following asset allocation breakdown:

Quality is an average of each bond’s credit rating, adjusted for its relative weighting in the portfolio. As of ~~September 30, 2020,~~March 31, 2021, our fixed income portfolio had the following rating distribution:

As of ~~September 30, 2020,~~March 31, 2021, the duration of the fixed income portfolio was ~~4.5~~4.8 years. Our fixed income portfolio remained well diversified, with ~~1,344~~1,435 individual issues.

Our investment portfolio has limited exposure to structured asset-backed securities. As of ~~September 30, 2020,~~March 31, 2021, we had ~~$135.3~~$137.8 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 ~~September 30, 2020,~~March 31, 2021, we had ~~$73.0~~$80.4 million in commercial mortgage-backed securities and ~~$396.9~~$369.2 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 ~~7.5~~7.6 percent of our investment portfolio at quarter end.

We had ~~$804.9~~$833.2 million in corporate fixed income securities as of ~~September 30, 2020,~~March 31, 2021, which includes ~~$100.3~~$107.5 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.

The municipal portfolio includes approximately 6659 percent tax-exempt securities and 3441 percent taxable securities. Approximately 8687 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.

The securities within the equity portfolio remain primarily invested in large-cap issues with a focus on dividend income and are a source of liquidity. In the equity portfolio, the strategy remains one of value investing, with security selection taking precedence over market timing.

As of ~~September 30, 2020,~~March 31, 2021, our equity portfolio had a dividend yield of ~~2.2~~2.0 percent, compared to ~~1.7~~1.4 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 ~~217~~213 individual securities and three ETF positions. No single ~~stock~~company exposure ~~is greater~~in the equity portfolio represents more than 21 percent of ~~the equity portfolio.~~invested assets.

Other invested assets include investments in low income housing tax credit partnerships, membership in the FHLBC and investments in private ~~funds and investments in restricted stock.~~funds. As of ~~September 30, 2020, $13.7~~March 31, 2021, $10.2 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 ~~nine-month~~three-month period ended ~~September 30, 2020,~~March 31, 2021, there were no outstanding borrowings with the FHLBC.

Our capital structure is comprised of equity and debt outstanding. As of ~~September 30, 2020,~~March 31, 2021, our capital structure consisted of ~~$149.4~~$149.5 million in 10-year maturity senior notes maturing in 2023 (debt) and ~~$1.1~~$1.2 billion of shareholders’ equity. Debt outstanding comprised ~~12.0~~11.5 percent of total capital as of ~~September 30, 2020.~~March 31, 2021. Interest and fees on debt obligations totaled ~~$5.7~~$1.9 million during each of the first ~~nine~~three months of ~~2020, compared to $5.6 million during the same period in 2019.~~2021 and 2020. We have incurred interest expense on debt at an average annual interest rate of 4.91 percent for the ~~nine-month~~three-month periods ended ~~September 30, 2020~~March 31, 2021 and ~~2019.~~2020.

We paid a regular quarterly cash dividend of $0.24 per share on ~~September 18, 2020,~~March 19, 2021, the same amount as the prior quarter. We have increased dividends in each of the last 45 years.

Our three insurance companies are subsidiaries of RLI Corp, with RLI Ins. as the first-level, or principal, insurance company. At the holding company (RLI Corp.) level, we rely largely on dividends from our insurance 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 ~~September 30, 2020,~~March 31, 2021, our holding company had ~~$1.1~~$1.2 billion 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 ~~$58.2~~$70.7 million in liquid assets, which ~~would cover~~exceeds our normal 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). In the first ~~nine~~three months of ~~2020,~~2021, RLI Ins. paid ~~$45.0~~$25.0 million in ordinary dividends to RLI Corp. In ~~2019,~~2020, our principal insurance subsidiary paid ordinary dividends totaling ~~$59.0~~$110.0 million. As of ~~September 30, 2020, $34.3~~March 31, 2021, $11.8 million of the net assets of our principal insurance subsidiary were not restricted and could be distributed to RLI Corp. as ordinary dividends without prior approval from the IDOI. Because the limitations are based upon a rolling 12-month period, the amount and impact of these restrictions vary over time. In addition to restrictions from our principal subsidiary’s insurance regulator, we also consider internal models and how capital adequacy is defined by our rating agencies in determining amounts available for distribution.

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 ~~2019~~2020 Annual Report on Form 10-K. The COVID-19 pandemic does present new and emerging uncertainty to the financial markets. See further discussion in Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations ~~and Part II, Item 1A., Risk Factors,~~ of this Quarterly Report on Form 10-Q.

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.

There have been no material changes from the risk factors previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, as updated in the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.

In 2010, our Board of Directors implemented a $100 million share repurchase program. We did not repurchase any shares during ~~2020.~~2021. We have $87.5 million of remaining capacity from the repurchase program. The repurchase program may be suspended or discontinued at any time without prior notice.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
