1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A. DESCRIPTION OF BUSINESS

RLI Corp. is an insurance holding company. References to “the Company,” “we,” “our,” “us” or like terms refer to the business of RLI Corp. and its subsidiaries. We underwrite select property and casualty insurance coverages through major subsidiaries collectively known as RLI Insurance 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.

On May 4, 2018, RLI Corp. changed its state of incorporation from the State of Illinois to the State of Delaware (the Reincorporation). The Reincorporation was effected by merging RLI Corp., an Illinois corporation (RLI Illinois), into RLI Corp., a Delaware corporation (RLI Delaware). The separate corporate existence of RLI Illinois ceased and RLI Delaware continues in existence as the surviving corporation and possesses all rights, privileges, powers and franchises of RLI Illinois. The Reincorporation did not result in any change in the name, business, management, fiscal year, location of the principal executive offices, assets or liabilities of the Company. 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 $66.4 million reclassification from common stock to paid-in-capital was made.

B. PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

The accompanying consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States of America (GAAP), which differ in some respects from those followed in reports to insurance regulatory authorities. The consolidated financial statements include the accounts of our holding company and our subsidiaries. Intercompany balances and transactions have been eliminated. Certain reclassifications were made to 2018 and 2017 to conform to the classifications used in the current year. The Company has evaluated subsequent events through the date these consolidated financial statements were issued. There were no subsequent events requiring adjustment to the financial statements or disclosure.

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-effect 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 December 31, 2019, $22.3 million of right-of-use assets and $24.5 million of lease liabilities were included in the other assets and other liabilities line items of the consolidated balance sheet, respectively, as a result of the adoption of these updates. 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 $0.6 million in 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)

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 (85 percent rated A or better at December 31, 2019) and we purchase reinsurance from financially strong reinsurers for which we already have an allowance for uncollectible reinsurance amounts, the effect of adoption will not have a material impact on our financial statements.

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, the effect of adoption will not have a material impact on our financial statements.

E. INVESTMENTS

Equity securities are carried at fair value with unrealized gains and losses recorded within net earnings in 2019 and 2018. Prior to 2018, unrealized gains and losses on equity securities were recognized through other comprehensive earnings. Investments in fixed income securities are classified into one of three categories: trading, held-to-maturity or available-for-sale. All of our fixed income securities are classified as available-for-sale and reported at fair value. Unrealized gains and losses on these securities are excluded from net earnings but are recorded as a separate component of comprehensive earnings and shareholders’ equity, net of deferred income taxes.

Other-than-Temporary Impairment

We regularly evaluate our fixed income securities using quantitative and qualitative criteria to determine impairment losses for other-than-temporary declines in the fair value of the investments. The following are the key factors for determining if a security is other-than-temporarily impaired:

● The length of time and the extent to which the fair value has been less than amortized cost,

● The probability of significant adverse changes to the cash flows,

● The occurrence of a discrete credit event resulting in the issuer defaulting on a material obligation, the issuer seeking protection from creditors under the bankruptcy laws, the issuer proposing a voluntary reorganization under which creditors are asked to exchange their claims for cash or securities having a fair value substantially lower than par value of their claims or

● The probability that we will recover the entire amortized cost basis of our fixed income securities prior to maturity.

Quantitative criteria considered during this process include, but are not limited to: the degree and duration of current fair value as compared to the amortized cost of the security, degree and duration of the security’s fair value being below cost and whether the issuer is in compliance with terms and covenants of the security. Qualitative criteria include the credit quality, current economic conditions, the anticipated speed of cost recovery, the financial health of and specific prospects for the issuer, as well as our absence of intent to sell or requirement to sell fixed income securities prior to recovery. In addition, we consider price declines in our other-than-temporary impairment (OTTI) analysis when they provide evidence of declining credit quality, and we distinguish between price changes caused by credit deterioration, as opposed to rising interest rates. See note 2 for further discussion of OTTI.

Interest on fixed maturities and short-term investments is credited to earnings on an accrual basis. Premiums and discounts are amortized or accreted over the lives of the related fixed maturities. Dividends on equity securities are credited to earnings on the ex-dividend date. Realized gains and losses on disposition of investments are based on specific identification of the investments sold on the settlement date.

F. CASH, SHORT-TERM INVESTMENTS AND OTHER INVESTED ASSETS

Cash consists of uninvested balances in bank accounts. Short-term investments consist of investments with original maturities of 90 days or less, primarily AAA-rated prime and government money market funds. Short-term investments are carried at cost. We have not experienced losses on these instruments. 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 cash, short-term investments, 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.

G. REINSURANCE

Ceded unearned premiums and reinsurance balances recoverable on paid and unpaid losses and settlement expenses are reported separately as assets, instead of being netted with the related liabilities, since reinsurance does not relieve the Company of our legal liability to our policyholders.

We continuously monitor the financial condition of our reinsurers. As part of our monitoring efforts, we review their annual financial statements, quarterly disclosures and Securities and Exchange Commission (SEC) filings for 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 recoverable tests, including one based on average default by S&P rating. Based upon our review and testing, our policy is to charge to earnings, in the form of an allowance, an estimate of unrecoverable amounts from reinsurers. This 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.

H. POLICY ACQUISITION COSTS

We defer incremental direct costs that relate to the successful acquisition of new or renewal insurance contracts, including commissions and premium taxes. Acquisition-related costs may be deemed ineligible for deferral when they are based on contingent or performance criteria beyond the basic acquisition of the insurance contract or when efforts to obtain or renew the insurance contract are unsuccessful. All eligible costs are capitalized and charged to expense in proportion to premium revenue recognized. The method followed in computing deferred policy acquisition costs limits the amount of such deferred costs to their estimated realizable value. This process contemplates the premiums to be earned, anticipated losses and settlement expenses and certain other costs expected to be incurred, but does not consider investment income. Judgments as to the ultimate recoverability of such deferred costs are reviewed on a segment basis and are highly dependent upon estimated future loss costs associated with the premiums written. This deferral methodology applies to both gross and ceded premiums and acquisition costs.

I. PROPERTY AND EQUIPMENT

Property and equipment are presented at cost less accumulated depreciation and are depreciated on a straight-line basis for financial statement purposes over periods ranging from 3 to 10 years for equipment and up to 30 years for buildings and improvements.

J. INVESTMENTS IN UNCONSOLIDATED INVESTEES

We maintain a 40 percent interest in the equity and earnings of Maui Jim, Inc. (Maui Jim), a manufacturer of high-quality sunglasses, which is accounted for under the equity method. We also maintain a similar minority representation on their board of directors. Maui Jim’s chief executive officer owns a controlling majority of the outstanding shares of Maui Jim. We carry this investment at the holding company level as it is not core to our insurance operations. Our investment in Maui Jim was $79.6 million at December 31, 2019 and $79.5 million at December 31, 2018. In 2019, we recorded $13.6 million in investee earnings for Maui Jim, compared to $12.5 million in 2018 and $14.4 million in 2017. Maui Jim recorded net income of $35.6 million in 2019, $30.3 million in 2018 and $34.4 million in 2017. Additional summarized financial information for Maui Jim for 2019 and 2018 is outlined in the following table:

(in millions)	2019		2018
Total assets	$	282.2	$	265.6
Total liabilities		104.8		90.4
Total equity		177.4		175.2

Approximately $69.3 million of undistributed earnings from Maui Jim are included in our retained earnings as of December 31, 2019. We received dividends of $13.2 million and $9.9 million from Maui Jim in 2019 and 2018, respectively. No dividends were received in 2017.

As of December 31, 2019, we had a 23 percent interest in the equity and earnings of Prime Holdings Insurance Services, Inc. (Prime), which is accounted for under the equity method. Prime writes business through two Illinois domiciled insurance carriers, Prime Insurance Company, an excess and surplus lines company, and Prime Property and Casualty Insurance Inc., an admitted insurance company. Our investment in Prime was $24.2 million at December 31, 2019 and $15.4 million at December

31, 2018. In 2019, we recorded $7.4 million in investee earnings for Prime, compared to $3.6 million in 2018 and $2.8 million in 2017. Additionally, we maintain a quota share reinsurance treaty with Prime, which contributed $13.1 million of gross premiums written and $28.7 million of net premiums earned during 2019, compared to $41.1 million of gross premiums written and $34.2 million of net premiums earned during 2018 and $29.6 million of gross premiums written and $21.0 million of net premiums earned during 2017. The decrease in gross written premium is reflective of our decreased quota share participation with Prime.

We perform annual impairment reviews of our investments in unconsolidated investees, which take into consideration current valuation and operating results. Based upon the most recent reviews, the assets were not impaired.

K. INTANGIBLE ASSETS

Goodwill and intangibles totaled $54.1 million and $54.5 million at December 31, 2019 and 2018, respectively, as detailed in the following table:

Goodwill and Intangible Assets
(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 $3,470 at 12/31/19 and $3,062 at 12/31/18		565		972
Total intangibles	$	8,065	$	8,472
Total goodwill and intangibles	$	54,127	$	54,534

As the amortization of goodwill and indefinite-lived intangible assets is not permitted, the assets are tested for impairment on an annual basis, or earlier if there is reason to suspect that their values may have been diminished or impaired. Annual impairment testing was performed on each of our goodwill and indefinite-lived intangible assets during 2019. Based upon these reviews, our energy surety goodwill, miscellaneous and contract surety goodwill, small commercial goodwill and state insurance license indefinite-lived intangible asset were not impaired. In addition, as of December 31, 2019, there were no triggering events on the above-mentioned goodwill and intangible assets that would suggest an updated review was necessary.

During the first quarter of 2018 and the second quarter of 2017, adverse loss experience triggered the need to test the medical professional liability reporting unit. The testing resulted in a $4.4 million non-cash impairment charge on goodwill and intangible assets in 2018 and a $3.4 million non-cash impairment charge on goodwill and intangible assets in 2017. In each instance, the fair value for the medical professional liability reporting unit’s agency relationships, carried as a definite-lived intangible asset, was determined by using a discounted cash flow valuation. In 2018, the carrying value exceeded the fair value, resulting in a $0.8 million non-cash impairment charge. In 2017, the resulting non-cash impairment charge on definite-lived intangibles was $1.8 million. The 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 in each year, resulting in a $3.6 million non-cash impairment charge in 2018 and a $1.6 million non-cash impairment charge during 2017. Subsequent to the 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 respective period’s consolidated statement of earnings.

The definite-lived intangible assets are amortized against future operating results based on their estimated useful lives. Amortization of intangible assets was $0.4 million, $0.4 million and $0.7 million for 2019, 2018 and 2017, respectively. We anticipate we will recognize amortization expense of $0.4 million in 2020, $0.1 million in 2021 and less than $0.1 million in 2022.

L. UNPAID LOSSES AND SETTLEMENT EXPENSES

The liability for unpaid losses and settlement expenses represents estimates of amounts needed to pay reported and unreported claims and related expenses. The estimates are based on certain actuarial and other assumptions related to the ultimate cost to settle such claims. Such assumptions are subject to occasional changes due to evolving economic, social and political conditions. All estimates are periodically reviewed and, as experience develops and new information becomes known, the reserves are adjusted as necessary. Such adjustments are reflected in the results of operations in the period in which they are determined. Due to the inherent uncertainty in estimating reserves for losses and settlement expenses, there can be no assurance that the ultimate liability will not exceed recorded amounts. If actual liabilities do exceed recorded amounts, there will be an adverse effect. Furthermore, we may determine that recorded reserves are more than adequate to cover expected losses, which would lead to a reduction in our reserves.

M. INSURANCE REVENUE RECOGNITION

Insurance premiums are recognized ratably over the term of the contracts, net of ceded reinsurance. Unearned premiums are calculated on a monthly pro rata basis.

N. INCOME TAXES

We file a consolidated federal income tax return. Federal income taxes are accounted for using the asset and liability method under which deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities, operating losses and tax credit carry forwards. The effect on deferred taxes for a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that all or some of the deferred tax assets will not be realized.

We consider uncertainties in income taxes and recognize those in our financial statements as required. As it relates to uncertainties in income taxes, our unrecognized tax benefits, including interest and penalty accruals, are not considered material to the consolidated financial statements. Also, no tax uncertainties are expected to result in significant increases or decreases to unrecognized tax benefits within the next 12-month period. Penalties and interest related to income tax uncertainties, should they occur, would be included in income tax expense in the period in which they are incurred.

As an insurance company, we are subject to minimal state income tax liabilities. On a state basis, since the majority of our income is from insurance operations, we pay premium taxes which are calculated as a percentage of gross premiums written in lieu of state income taxes. Premium taxes are a component of policy acquisition costs.

O. EARNINGS PER SHARE

Basic earnings per share (EPS) 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 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 these items. The following represents a reconciliation of the numerator and denominator of the basic and diluted EPS computations contained in the consolidated financial statements:

			Weighted Average
	Income		Shares	Per Share
(in thousands, except per share data)	(Numerator)		(Denominator)	Amount

P. COMPREHENSIVE EARNINGS

Our comprehensive earnings include net earnings plus after-tax unrealized gains and losses on our available-for-sale fixed income portfolio in 2019 and 2018. In 2017, after-tax unrealized gains and losses on our equity portfolio were also included. With the adoption of ASU 2016-01, Financial Instruments – Overall (subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, on January 1, 2018, we began recognizing unrealized gains and losses on the equity portfolio through net income. In reporting the components of comprehensive earnings, we used the federal statutory tax rate of 21 percent in 2019 and 2018 and 35 percent in 2017. Other comprehensive income (loss), as shown in the consolidated statements of earnings and comprehensive earnings, is net of tax expense (benefit) of $17.8 million, $(9.0) million and $19.0 million for 2019, 2018 and 2017, respectively.

The table below illustrates the changes in the balance of each component of accumulated other comprehensive earnings for each period presented in the consolidated financial statements. The 2017 activity and balances include the net unrealized gain and loss activity on both fixed income and equity securities, while the 2019 and 2018 activity and ending balance reflect only the net unrealized gain and loss activity on fixed income securities due to the aforementioned adoption of ASU 2016-01. The changes in accumulated other comprehensive earnings also reflect adjustments from the adoption of two accounting standards. ASU 2016-01 necessitated a cumulative-effect adjustment in 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. Deferred tax items are required to be revalued based on new tax laws with changes included in earnings. Since other comprehensive earnings was not affected by the revaluation of 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. As previously mentioned, 2019 and 2018 reflect activity on available-for-sale fixed income securities, while 2017 also includes activity from the equity portfolio.

Q. FAIR VALUE DISCLOSURES

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, Agencies, Government and Municipal securities are deemed Level 2.

Mortgage-backed Securities (MBS)/Collateralized Mortgage Obligations (CMO) 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 CMO 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/CMO and ABS with corroborated, observable inputs are classified as Level 2. All of our MBS/CMO and ABS are deemed Level 2.

Regulation D Private Placement Securities: 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. All Regulation D privately placed bonds are classified as corporate securities and deemed Level 3.

For all of our fixed income securities, 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 our 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 fixed income securities provided by our pricing services are reasonable.

Common Stock: As of December 31, 2019, 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 security not traded on an exchange in 2018 was provided by a third-party pricing source and was 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. The fair value of our long-term debt is discussed further in note 4.

R. STOCK-BASED COMPENSATION

We expense the estimated fair value of employee stock options and similar awards. We measure compensation cost for awards of equity instruments to employees based on the grant-date fair value of those awards and recognize compensation expense over the service period that the awards are expected to vest. The tax effects related to share-based payments are made through net earnings. See note 8 for further discussion and related disclosures regarding stock options.

S. RISKS AND UNCERTAINTIES

Certain risks and uncertainties are inherent to our day-to-day operations and to the process of preparing our consolidated financial statements. The more significant risks and uncertainties, as well as our attempt to mitigate, quantify and minimize such risks, are presented below and throughout the notes to the consolidated financial statements.

Insurance Risks

We compete with a large number of other companies in our selected lines of business. During periods of intense competition for premium, we are vulnerable to the actions of other companies who may seek to write business without the appropriate regard for risk and profitability. The insurance industry is currently operating under highly competitive conditions and, as a result, margins in the industry are under pressure. During these times, it is very difficult to grow or maintain premium volume without sacrificing underwriting discipline and income. Our profitability can be significantly affected by the ability of our underwriters to accurately select and price risk and our claim personnel to appropriately deliver fair outcomes. We attempt to mitigate this risk by incentivizing our underwriters to maximize underwriting profit and remain disciplined in pricing and selecting risks. If we are unable to compete effectively in the markets in which we operate or expand our operations into new markets, our underwriting revenues may decline, as well as overall business results.

Our loss reserves are based on estimates and may be inadequate to cover our actual insured losses, which would negatively impact our profitability. As of December 31, 2019, we had $1.6 billion of gross loss and LAE reserves. Significant periods of time often elapse between the occurrence of an insured loss, the reporting of the loss to the Company and our payment of that loss. As part of the reserving process, we review historical data and consider the impact of various factors such as trends in claim frequency and severity, emerging economic and social trends, inflation and changes in the regulatory and litigation environments. If the actual amount of insured losses is greater than the amount we have reserved for these losses, our profitability would suffer.

Catastrophe Exposures

Our insurance coverages include exposure to catastrophic events. We monitor all catastrophe exposures by quantifying our exposed policy limits in each region and by using computer-assisted modeling techniques. Additionally, we limit our risk to such catastrophes through restraining the total policy limits written in each region and by purchasing reinsurance. Our major catastrophe exposure is to losses caused by earthquakes, primarily on the West Coast. In 2019, we had reinsurance protection of $400 million in excess of $25 million first-dollar retention for earthquakes in California and $425 million in excess of a $25 million first-dollar retention for earthquakes outside of California. These amounts are subject to certain co-participations by the Company on losses in excess of the $25 million retentions. Our second largest catastrophe exposure is to losses caused by wind storms to commercial properties throughout the Gulf and East Coasts, as well as to homes we insure in Hawaii. In 2019, these coverages were supported by $275 million in excess of a $25 million first-dollar retention in traditional catastrophe reinsurance protection, subject to certain co-participations by the Company in the excess layers. In addition, we have incidental exposure to international catastrophic events.

Our catastrophe reinsurance treaty renewed on January 1, 2020. We purchased the same limits over the same first-dollar retention amounts outlined above, subject to certain retentions by us in the excess layers. We actively manage our catastrophe program to keep our net retention in line with risk tolerances and to optimize the risk/return trade off.

Environmental Exposures

We are subject to environmental claims and exposures primarily through our commercial excess, general liability and discontinued assumed casualty reinsurance lines of business. Although exposure to environmental claims exists in these lines of business, we seek to mitigate or control the extent of this exposure on the vast majority of this business through the following methods: (1) our policies include pollution exclusions that have been continually updated to further strengthen them, (2) our policies primarily cover moderate hazard risks and (3) we began writing this business after the insurance industry became aware of the potential pollution liability exposure and implemented changes to limit exposure to this hazard.

We offer coverage for low to moderate environmental liability exposures for small contractors and asbestos and mold remediation specialists. We also provide limited coverage for individually underwritten underground storage tanks. The overall exposure is mitigated by focusing on smaller risks with low to moderate exposures. Risks that have large-scale exposures are avoided including petrochemical, chemical, mining, manufacturers and other risks that might be exposed to superfund sites. This business is covered under our casualty ceded reinsurance treaties.

We made loss and settlement expense payments on environmental liability claims and have loss and settlement expense reserves for others. We include this historical environmental loss experience with the remaining loss experience in the applicable line of business to project ultimate incurred losses and settlement expenses as well as related incurred but not reported (IBNR) loss and settlement expense reserves.

Although historical experience on environmental claims may not accurately reflect future environmental exposures, we used this experience to record loss and settlement expense reserves in the exposed lines of business. See further discussion of environmental exposures in note 6.

Reinsurance

Reinsurance does not discharge the Company from our primary liability to policyholders, and to the extent that a reinsurer is unable to meet its obligations, we would be liable. We continuously monitor the financial condition of prospective and existing reinsurers. As a result, we purchase reinsurance from a number of financially strong reinsurers. We provide an allowance for reinsurance balances deemed uncollectible. See further discussion of reinsurance exposures in note 5.

Investment Risk

Our investment portfolio is subject to market, credit and interest rate risks. The equity portfolio will fluctuate with movements in the overall stock market. While the equity portfolio has been constructed to have lower downside risk than the market, the portfolio is positively correlated with movements in domestic stocks. The bond portfolio is affected by interest rate changes and movement in credit spreads. We attempt to mitigate our interest rate and credit risks by constructing a well-diversified portfolio with high-quality securities with varied maturities. Downturns in the financial markets could have a negative effect on our portfolio. However, we attempt to manage this risk through asset allocation, duration and security selection.

Liquidity Risk

Liquidity is essential to our business and a key component of our concept of asset-liability matching. Our liquidity may be impaired by an inability to collect premium receivable or reinsurance recoverable balances in a timely manner, an inability to sell assets or redeem our investments, an inability to access funds from our insurance subsidiaries, unforeseen outflows of cash or large claim payments or an inability to access debt or equity capital markets. This situation may arise due to circumstances that we may be unable to control, such as a general market disruption, an operational problem that affects third parties or the Company, or even by the perception among market participants that we, or other market participants, are experiencing greater liquidity risk.

Our credit ratings are important to our liquidity. A reduction in our credit ratings could adversely affect our liquidity and competitive position by increasing our borrowing costs or limiting our access to the capital markets.

Financial Statements

The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenues and expenses. The most significant of these amounts is the liability for unpaid losses and settlement expenses. Other estimates include investment valuation and OTTIs, the collectability of reinsurance balances, recoverability of deferred tax assets and deferred policy acquisition costs. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. Although recorded estimates are supported by actuarial computations and other supportive data, the estimates are ultimately based on our expectations of future events. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the consolidated financial statements in future periods.

External Factors

Our insurance subsidiaries are highly regulated by the state in which they are incorporated and by the states in which they do business. Such regulations, among other things, limit the amount of dividends, impose restrictions on the amount and types of investments and regulate rates insurers may charge for various coverages. We are also subject to insolvency and guaranty fund assessments for various programs designed to ensure policyholder indemnification. We generally accrue an assessment during the period in which it becomes probable that a liability has been incurred from an insolvency and the amount of the related assessment can be reasonably estimated.

The National Association of Insurance Commissioners (NAIC) has developed Property/Casualty Risk-Based Capital (RBC) standards that relate an insurer’s reported statutory surplus to the risks inherent in its overall operations. The RBC formula uses the statutory annual statement to calculate the minimum indicated capital level to support investment and underwriting risk. The NAIC model law calls for various levels of regulatory action based on the magnitude of an indicated RBC capital deficiency, if any. We regularly monitor our subsidiaries’ internal capital requirements and the NAIC’s RBC developments. As of December 31, 2019, we determined that our capital levels are well in excess of the minimum capital requirements for all RBC action levels and that our capital levels are sufficient to support the level of risk inherent in our operations. See note 9 for further discussion of statutory information and related insurance regulatory restrictions.

In addition, ratings are a critical factor in establishing the competitive position of insurance companies. Our insurance companies are rated by AM Best, S&P and Moody’s. Their ratings reflect their opinions of an insurance company’s and an insurance holding company’s financial strength, operating performance, strategic position and ability to meet its obligations to policyholders.
