Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Practices	Note 2 – Summary of Significant Accounting Policies and Practices The consolidated financial statements and notes thereto have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and are reported in U.S. currency. American National consolidates entities that are wholly-owned and those in which American National owns less than 100% but controls, as well as variable interest entities in which American National is the primary beneficiary. Intercompany balances and transactions with consolidated entities have been eliminated. Investments in unconsolidated affiliates are accounted for using the equity method of accounting. Certain amounts in prior years have been reclassified to conform to current year presentation. The interim consolidated financial statements and notes herein are unaudited and reflect all adjustments which management considers necessary for the fair presentation of the interim consolidated statements of financial position, operations, comprehensive income, changes in equity, and cash flows. The interim consolidated financial statements and notes should be read in conjunction with the annual consolidated financial statements and notes thereto included in American National’s Annual Report on Form 10-K The preparation of the consolidated financial statements in conformity with GAAP requires the use of estimates and assumptions that affect the reported consolidated financial statement balances. Actual results could differ from those estimates.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	Note 3 – Recently Issued Accounting Pronouncements Future Adoption of New Accounting Standards In February 2016, the FASB issued guidance that will require significant changes to the statement of financial position of lessees. With certain limited exceptions, lessees will need to recognize virtually all of their leases on the statement of financial position, by recording a right-of-use right-of-use In June 2016, the FASB issued guidance that will significantly change how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance will replace the current “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. For available-for-sale In February 2018, the FASB issued guidance that allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The standard is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018. The Company plans to adopt the standard effective January 1, 2019. The guidance changes equity presentation only and will not have an impact on the Company’s consolidated financial position, results of operations, equity or cash flows. Adoption of New Accounting Standards In May 2014, the FASB issued guidance that superseded most existing revenue recognition requirements in GAAP. Insurance contracts generally are excluded from the scope of the guidance. For those contracts which are impacted, the transaction price is attributed to the underlying performance obligations in the contract and revenue is recognized as the entity satisfies the performance obligations and transfers control of a good or service to the customer. The Company’s revenues include premium, other policy revenue, net investment income, realized investment gains, and other income. Other income includes fee income which is recognized when obligations under the terms specified within a contract with a customer are either (1) satisfied at a point in time or (2) the progress of completion is measured over a period of time as the obligation is performed using the input method. The Company adopted the standard on its required effective date of January 1, 2018 using the modified retrospective approach. The majority of our revenue sources are insurance related and not in the scope of the guidance. The adoption of the standard did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows as of the adoption date or for the six months ended June 30, 2018. In January 2016, the FASB issued guidance that changed certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The new guidance requires that equity investments, other than those accounted for under the equity method or those that result in consolidation of the investee, be measured at fair value and the changes in fair value are recognized through earnings. When the fair value option has been elected for financial liabilities, changes in fair value due to instrument-specific credit risk will be recognized separately in other comprehensive income. The guidance also simplifies the impairment assessment of equity investments and eliminates the disclosure requirements for methods and significant assumptions used to estimate fair value of financial instruments that are measured at amortized cost on the statement of financial position. The Company adopted the standard on its required effective date of January 1, 2018 using a modified retrospective approach. Upon adoption, cumulative unrealized gains and losses on equity securities of $667.7 million, partially offset by $30.4 million participating policyholders’ interest, net of tax, related to unrealized gains and losses on equity securities, were reclassified from accumulated other comprehensive income to retained earnings. In April 2018, an additional $10.2 million deferred policy acquisition cost adjustment, net of tax, related to net unrealized gains and losses on equity securities, was reclassified from accumulated other comprehensive income to retained earnings. Earnings increased $35.1 million and $9.4 million, net of tax, for the three and six months ended June 30, 2018, respectively from the change in unrealized gains and losses on equity securities. In October of 2016, the FASB issued guidance requiring an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Whereas, prior guidance prohibited the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset was sold to an outside party. The Company adopted the standard on its required effective date of January 1, 2018 using a modified retrospective approach. Upon adoption, an other liability was released and retained earnings increased by $59.9 million. The adoption of the standard did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows for the six months ended June 30, 2018. In March 2017, the FASB issued guidance on the presentation of net periodic pension and postretirement benefit costs. The guidance requires the service cost component to be reported in the same line item as other compensation costs. All other components of net periodic pension cost are required to be presented in the income statement separately from the service cost component and outside of income from operations. The Company adopted the standard on its required effective date of January 1, 2018 using a retrospective approach. Upon adoption, other components of net periodic pension costs of $5.6 million and $6.8 million, net of tax, for the three and six months ended June 30, 2017, respectively, were reclassified from other operating expenses. The guidance changed presentation only and did not have an impact on the Company’s consolidated financial position, results of operations, equity or cash flows. Since the Company’s defined benefit pension plans have been frozen, the components of net periodic benefit costs have not materially changed from year-end

Total mortgage loans were also net of unamortized origination fees of $31,510,000 and $32,766,000 at June 30, 2018 and December 31, 2017, respectively. No unearned income is included in these amounts. Allowance for Credit Losses A loan is considered impaired when it is probable that all amounts due will not be collected according to the contractual terms of the loan agreement. Mortgage loans with temporary difficulties are not considered impaired when the borrower has the financial capacity to fund revenue shortfalls from the properties for the foreseeable future. Individual valuation allowances are established for impaired loans to reduce the carrying value to the fair value of the collateral. Loans not evaluated individually for collectability are segregated by property-type and location, and allowance factors are applied. These factors are developed based on historical loss experience adjusted for the expected trend in the rate of foreclosure losses. Allowance factors are higher for loans of certain property types and in certain regions based on loss experience or a blended historical loss factor. The change in allowance for credit losses in mortgage loans is shown below (in thousands, except number of loans): Collectively Evaluated for Impairment Individually Impaired Total Number of Recorded Valuation Number of Recorded Valuation Number of Recorded Valuation Beginning balance at January 1, 2018 451 $ 4,762,315 16,041 3 $ 6,550 2,825 454 $ 4,768,865 $ 18,866 Change in allowance — — 554 — — (509 ) — — 45 Net change in recorded investment 5 366,504 — (1 ) (1,940 ) — 4 364,564 — Ending balance at June 30, 2018 456 $ 5,128,819 $ 16,595 2 $ 4,610 $ 2,316 458 $ 5,133,429 $ 18,911 Troubled Debt Restructurings American National has granted concessions which are classified as troubled debt restructurings to certain mortgage loan borrowers. Concessions are generally one of, or a combination of, a delay in payment of principal or interest, a reduction of the contractual interest rate or an extension of the maturity date. American National considers the amount, timing and extent of concessions in determining any impairment or changes in the specific allowance for loan losses recorded in connection with a troubled debt restructuring. The carrying value after specific allowance, before and after modification in a troubled debt restructuring, may not change significantly, or may increase if the expected recovery is higher than the pre-modification Troubled debt restructuring mortgage loan information is as follows (in thousands, except number of loans): Six months ended June 30, 2018 2017 Number of loans Recorded investment pre- modification Recorded Number of loans Recorded investment pre- modification Recorded Other (hotel/motel) — $ — $ — 5 $ 24,801 $ 24,801 Total — $ — $ — 5 $ 24,801 $ 24,801 There were no loans determined to be troubled debt restructurings for the six months ended June 30, 2018.

American National frequently participates in the design of these entities with the sponsor, but in most cases, its involvement is limited to financing. Through analysis performed by American National, some of these partnerships and joint ventures have been determined to be variable interest entities (“VIEs”). In certain instances, in addition to an economic interest in the entity, American National holds the power to direct the most significant activities of the entity and is deemed the primary beneficiary or consolidator of the entity. The assets of the consolidated VIEs are restricted and must first be used to settle their liabilities. Creditors or beneficial interest holders of these VIEs have no recourse to the general credit of American National, as American National’s obligation is limited to the amount of its committed investment. American National has not provided financial or other support to the VIEs in the form of liquidity arrangements, guarantees, or other commitments to third parties that may affect the fair value or risk of its variable interest in the VIEs in 2018 or 2017. The assets and liabilities relating to the VIEs included in the consolidated financial statements are as follows (in thousands): June 30, 2018 December 31, 2017 Investment real estate $ 143,154 $ 148,456 Short-term investments 501 501 Cash and cash equivalents 10,365 6,320 Other receivables 4,447 4,461 Other assets 13,651 15,920 Total assets of consolidated VIEs $ 172,118 $ 175,658 Notes payable $ 136,730 $ 137,458 Other liabilities 5,373 5,616 Total liabilities of consolidated VIEs $ 142,103 $ 143,074 The notes payable in the consolidated statements of financial position pertain to the borrowings of the consolidated VIEs.

A fair value hierarchy is used to determine fair value based on a hypothetical transaction at the measurement date from the perspective of a market participant. American National has evaluated the types of securities in its investment portfolio to determine an appropriate hierarchy level based upon trading activity and the observability of market inputs. The classification of assets or liabilities within the fair value hierarchy is based on the lowest level of significant input to its valuation. The input levels are defined as follows: Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 Quoted prices in markets that are not active or inputs that are observable directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities other than quoted prices in Level 1; quoted prices in markets that are not active; or other inputs that are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Unobservable inputs reflect American National’s own assumptions about the assumptions that market participants would use in pricing the asset or liability. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models and third-party evaluation, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Fixed Maturity Securities and Equity Options — The pricing service utilizes market quotations for fixed maturity securities that have quoted prices in active markets. Since fixed maturity securities generally do not trade on a daily basis, the pricing service prepares estimates of fair value measurements for these securities using its proprietary pricing applications, which include available relevant market information, benchmark curves, benchmarking of like securities, sector groupings and matrix pricing. Additionally, an option adjusted spread model is used to develop prepayment and interest rate scenarios. The pricing service evaluates each asset class based on relevant market information, credit information, perceived market movements and sector news. The market inputs utilized in the pricing evaluation, listed in the approximate order of priority, include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided American National has reviewed the inputs and methodology used and the techniques applied by the pricing service to produce quotes that represent the fair value of a specific security. The review confirms that the pricing service is utilizing information from observable transactions or a technique that represents a market participant’s assumptions. American National does not adjust quotes received from the pricing service. The pricing service utilized by American National has indicated that they will only produce an estimate of fair value if there is objectively verifiable information available. American National holds a small amount of private placement debt and fixed maturity securities that have characteristics that make them unsuitable for matrix pricing. For these securities, a quote from an independent broker (typically a market maker) is obtained. Due to the disclaimers on the quotes that indicate that the price is indicative only, American National includes these fair value estimates in Level 3. For securities priced using a quote from an independent broker, such as the equity-indexed options and certain fixed maturity securities, American National uses a market-based fair value analysis to validate the reasonableness of prices received. Price variances above a certain threshold are analyzed further to determine if any pricing issue exists. This analysis is performed quarterly. Equity Securities — Mortgage Loans — Embedded Derivative — • Lapse rate assumptions are determined by company experience. Lapse rates are generally assumed to be lower during a contract’s surrender charge period and then higher once the surrender charge period has ended. Decreases to the assumed lapse rates generally increase the fair value of the liability as more policyholders persist to collect the crediting interest pertaining to the indexed product. Increases to the lapse rate assumption will have the inverse effect decreasing the fair value. • Mortality rate assumptions vary by age and by gender based on company and industry experience. Decreases to the assumed mortality rates increase the fair value of the liabilities as more policyholders earn crediting interest. Increases to the assumed mortality rates decrease the fair value as higher decrements reduce the potential for future interest credits. • Equity volatility assumptions begin with current market volatilities and grow to long-term values. Increases to the assumed volatility will increase the fair value of liabilities, as future projections will produce higher increases in the linked index. At June 30, 2018 and December 31, 2017, the one year implied volatility used to estimate embedded derivative value was 13.7%. Fair values of indexed life and annuity liabilities are calculated using the discounted cash flow technique. Shown below are the significant unobservable inputs used to calculate the Level 3 fair value of the embedded derivatives within policyholder contract deposits (in millions, except range percentages): Fair Value Range June 30, 2018 December 31, 2017 Unobservable Input June 30, 2018 December 31, 2017 Indexed Annuities $ 581.6 $ 498.3 Lapse Rate 1-66 % 1-66 % Mortality Multiplier 90-100 % 90-100 % Equity Volatility 10-40 % 7-30 % Indexed Life 11.3 14.2 Equity Volatility 10-40 % 7-30 % Other Financial Instruments — Policy loans—The carrying value of policy loans is the outstanding balance plus any accrued interest. Due to the collateralized nature of policy loans such that they cannot be separated from the policy contracts, the unpredictable timing of repayments and the fact that settlement is at outstanding value, American National believes the carrying value of policy loans approximates fair value. Investment contracts —The carrying value of investment contracts is equivalent to the accrued account balance. The accrued account balance consists of deposits, net of withdrawals, plus or minus interest credited, fees and charges assessed and other adjustments. American National believes that the carrying value of investment contracts approximates fair value because the majority of these contracts’ interest rates reset at anniversary. Notes payable— Notes payable are carried at outstanding principal balance. The carrying value of the notes payable approximates fair value because the underlying interest rates approximate market rates at the balance sheet date.

relating to assets still held at June 30, 2018, and 2017, respectively. There were no transfers between Level 1 and Level 2 fair value hierarchies during the periods presented. The transfers into Level 3 during the six months ended June 30, 2017 were the result of existing securities no longer being priced by the third-party pricing service at the end of the period. Unless information is obtained from the brokers that indicate observable inputs were used in their pricing, there are not enough observable inputs to enable American National to classify the securities priced by the brokers as other than Level 3. American National’s valuation of these securities involves judgment regarding assumptions market participants would use including quotes from independent brokers. The inputs used by the brokers include recent transactions in the security, similar bonds with same name, ratings, maturity and structure, external dealer quotes in the security, Bloomberg evaluated pricing and prior months pricing. None of them are observable to American National as of June 30, 2018. The transfers out of Level 3 during the six months ended June 30, 2017 were securities being priced by the third-party service at the end of the period, using inputs that are observable or derived from market data, which resulted in classification of these assets as Level 2.

Insurance [Abstract]
Liability for Unpaid Claims and Claim Adjustment Expenses	Note 11 – Liability for Unpaid Claims and Claim Adjustment Expenses The liability for unpaid claims and claim adjustment expenses (“claims”) for accident and health, and property and casualty insurance is included in “Policy and contract claims” in the consolidated statements of financial position and is the amount estimated for incurred but not reported (“IBNR”) claims and claims that have been reported but not settled. Liability for unpaid claims are estimated based upon American National’s historical experience and actuarial assumptions that consider the effects of current developments, anticipated trends and risk management programs, less anticipated salvage and subrogation. The effects of the changes are included in the consolidated results of operations in the period in which the changes occur. The time value of money is not taken into account for the purposes of calculating the liability for unpaid claims. There have been no significant changes in methodologies or assumptions used to calculate the liability for unpaid claims and claim adjustment expenses. Information regarding the liability for unpaid claims is shown below (in thousands): Six months ended June 30, 2018 2017 Unpaid claims balance, beginning $ 1,199,233 $ 1,140,723 Less reinsurance recoverables 237,439 216,903 Net beginning balance 961,794 923,820 Incurred related to Current 596,530 563,959 Prior years (12,515 ) (40,137 ) Total incurred claims 584,015 523,822 Paid claims related to Current 288,591 288,731 Prior years 240,544 205,702 Total paid claims 529,135 494,433 Net balance 1,016,845 953,209 Plus reinsurance recoverables 255,684 195,072 Unpaid claims balance, ending $ 1,272,529 $ 1,148,281 The net and gross reserve calculations have shown favorable development as a result of favorable loss emergence compared to what was implied by the loss development patterns used in the original estimation of losses in prior years. Estimates for ultimate incurred claims attributable to insured events of prior years decreased by approximately $12,515,000 during the first six months of 2018 and decreased by approximately $40,137,000 during the first six months of 2017. This reflected lower-than-anticipated losses in the first six months of 2018 related to accident years prior to 2018 in workers compensation, other commercial, and business owner and commercial package policy lines of business. For short-duration health insurance claims, the total of IBNR plus expected development on reported claims included in the liability for unpaid claims and claim adjustment expenses at June 30, 2018 was $44,443,000.

Management assesses both positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of its existing deferred tax assets. During the three months ended June 30, 2018, management determined that it is more-likely-than-not There are no operating or capital loss carryforwards that will expire by December 31, 2018. American National’s federal income tax returns for years 2014 to 2016 are subject to examination by the Internal Revenue Service. With few exceptions, American National is no longer subject to examination for years before 2014. During the six months ended June 30, 2018, we received $48.0 million in refunds related to 2013, 2014, 2015, and 2016. In the opinion of management, all prior year deficiencies have been paid or adequate provisions have been made for any tax deficiencies that may be upheld. No provision for penalties or interest were established during 2018 relating to a dispute with the Internal Revenue Service. Management does not believe there are any uncertain tax benefits that could be recognized within the next twelve months that would decrease American National’s effective tax rate.

The SARs vest at a rate of 20% per year for five years and expire five years after vesting. RS awards entitle the participant to full dividend and voting rights. Each RS share awarded has the value of one share of restricted stock and vests 10 years from the grant date. Unvested shares are restricted as to disposition, and are subject to forfeiture under certain circumstances. Compensation expense is recognized over the vesting period. The restrictions on these awards lapse after 10 years and most of these awards feature a graded vesting schedule in the case of the retirement, death or disability of an award holder. Restricted stock awards for 350,334 shares have been granted at an exercise price of zero, of which 11,333 shares are unvested. RSU awards allow the recipient of the awards to settle the vested RSUs in either shares of American National’s common stock, cash or a combination of both. RSUs granted vest after a one-year Earnings per share Basic earnings per share were calculated using a weighted average number of shares outstanding. Diluted earnings per share include RS and RSU award shares.

RBC is calculated using formulas applied to certain financial balances and activities that consider, among other things, investment risks related to the type and quality of investments, insurance risks associated with products and liabilities, interest rate risks and general business risks. Insurance companies that do not maintain capital and surplus at a level at least 200% of the authorized control level RBC are required to take certain actions. At June 30, 2018 and December 31, 2017, American National Insurance Company’s statutory capital and surplus was $3,234,095,000 and $3,293,474,000, respectively. American National Insurance Company and each of its insurance subsidiaries had statutory capital and surplus at June 30, 2018 and December 31, 2017, substantially above 200% of the authorized control level. American National and its insurance subsidiaries prepare statutory-basis financial statements in accordance with statutory accounting practices prescribed or permitted by the insurance department of the state of domicile, which include certain components of the National Association of Insurance Commissioners’ Codification of Statutory Accounting Principles (“NAIC Codification”). NAIC Codification is intended to standardize regulatory accounting and reporting to state insurance departments. However, statutory accounting practices continue to be established by individual state laws and permitted practices. Modifications by the various state insurance departments may impact the statutory capital and surplus of American National Insurance Company and its insurance subsidiaries. Statutory accounting differs from GAAP primarily by charging policy acquisition costs to expense as incurred, establishing future policy benefit liabilities using different actuarial assumptions, and valuing securities on a different basis. In addition, certain assets are not admitted under statutory accounting principles and are charged directly to surplus. One of American National’s insurance subsidiaries has been granted a permitted practice from the Missouri Department of Insurance to record as the valuation of its investment in a wholly-owned subsidiary that is the attorney-in-fact The statutory capital and surplus and net income of our life and property and casualty insurance entities in accordance with statutory accounting practices are shown below (in thousands): June 30, 2018 December 31, 2017 Statutory capital and surplus Life insurance entities $ 2,074,948 $ 2,141,573 Property and casualty insurance entities 1,170,214 1,162,761 Three months ended June 30, Six months ended June 30, 2018 2017 2018 2017 Statutory net income (loss) Life insurance entities $ 12,850 $ 20,809 $ 16,113 $ 18,342 Property and casualty insurance entities (3,828 ) (5,639 ) 9,230 1,172 Dividends American National Insurance Company’s payment of dividends to stockholders is restricted by insurance law. The restrictions require life insurance companies to maintain minimum amounts of capital and surplus, and in the absence of special approval, limit the payment of dividends to the greater of the prior year’s statutory net income from operations, or 10% of prior year statutory surplus. American National Insurance Company is permitted without prior approval of the Texas Department of Insurance to pay total dividends of $329,347,000 during 2018. Similar restrictions on amounts that can transfer in the form of dividends, loans, or advances to American National Insurance Company apply to its insurance subsidiaries. Noncontrolling interests American National County Mutual Insurance Company (“County Mutual”) is a mutual insurance company owned by its policyholders. American National has a management agreement that effectively gives it control of County Mutual. As a result, County Mutual is included in the consolidated financial statements of American National. Policyholder interests in the financial position of County Mutual are reflected as noncontrolling interest of $6,750,000 at June 30, 2018 and December 31, 2017. American National Insurance Company and its subsidiaries exercise control or ownership of various joint ventures, resulting in their consolidation into American National’s consolidated financial statements. The interests of the other partners in the consolidated joint ventures are shown as noncontrolling interests of $1,096,000 and $2,262,000 at June 30, 2018 and December 31, 2017, respectively.

Segment Reporting [Abstract]
Segment Information	Note 15– Segment Information Management organizes the business into five operating segments: • Life—consists of whole, term, universal, indexed and variable life insurance. Products are primarily sold through career, multiple-line, and independent agents as well as direct marketing channels. • Annuity—consists of fixed, indexed, and variable annuity products. Products are primarily sold through independent agents, brokers, and financial institutions, along with multiple-line and career agents. • Health—consists of medicare supplement, stop loss, other supplemental health products and credit disability insurance. Products are typically distributed through independent agents and managing general underwriters. • Property and Casualty—consists of personal, agricultural and targeted commercial coverages and credit-related property insurance. Products are primarily sold through multiple-line and independent agents. • Corporate and Other—consists of net investment income from investments and certain expenses not allocated to the insurance segments and revenues and related expenses from non-insurance The accounting policies of the segments are the same as those described in Note 2 to American National’s 2017 annual report on Form 10-K. • Recurring income from bonds and mortgage loans is allocated based on the assets allocated to each line of business at the average yield available from these assets. • Net investment income from all other assets is allocated to the insurance segments in accordance with the amount of capital allocated to each segment, with the remainder recorded in the Corporate and Other business segment. • Expenses are allocated based upon various factors, including premium and commission ratios of the operating segments.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 16 – Commitments and Contingencies Commitments American National had aggregate commitments at June 30, 2018, to purchase, expand or improve real estate, to fund fixed interest rate mortgage loans, and to purchase other invested assets of $748,380,000 of which $381,365,000 is expected to be funded in 2018 with the remainder funded in 2019 and beyond. American National has a $100,000,000 short-term variable rate borrowing facility containing a $55,000,000 sub-feature Federal Home Loan Bank (FHLB) Agreements In May 2018, the Company became a member of the Federal Home Loan Bank of Dallas (“FHLB”) to augment its liquidity resources. As membership requires the ownership of member stock, the Company purchased $7.0 million of stock to meet the FHLB’s membership requirement. The FHLB member stock is recorded in other invested assets on the Company’s consolidated statements of financial position. Through its membership, the Company has access to the FHLB’s financial services including advances that provide an attractive funding source for short-term borrowing and for access to other funding agreements. As of June 30, 2018, certain collateralized mortgage obligations (CMO’s) with a fair value of approximately $132.5 million were on deposit with the FHLB as collateral for amounts subject to funding agreements. The deposited securities are included in bonds held-to-maturity Guarantees American National has guaranteed bank loans for customers of a third-party marketing operation. The bank loans are used to fund premium payments on life insurance policies issued by American National. The loans are secured by the cash values of the life insurance policies. If the customer were to default on a bank loan, American National would be obligated to pay off the loan. As the cash values of the life insurance policies always equal or exceed the balance of the loans, management does not foresee any loss on these guarantees. The total amount of the guarantees outstanding as of June 30, 2018, was approximately $196,442,000, while the total cash value of the related life insurance policies was approximately $202,089,000. Litigation American National and certain subsidiaries, in common with the insurance industry in general, are defendants in various lawsuits concerning alleged breaches of contracts, various employment matters, allegedly deceptive insurance sales and marketing practices, and miscellaneous other causes of action arising in the ordinary course of operations. Certain of these lawsuits include claims for compensatory and punitive damages. We provide accruals for these items to the extent we deem the losses probable and reasonably estimable. After reviewing these matters with legal counsel, based upon information presently available, management is of the opinion that the ultimate resultant liability, if any, would not have a material adverse effect on American National’s consolidated financial position, liquidity or results of operations; however, assessing the eventual outcome of litigation necessarily involves forward-looking speculation as to judgments to be made by judges, juries and appellate courts in the future. Such speculation warrants caution, as the frequency of large damage awards, which bear little or no relation to the economic damages incurred by plaintiffs in some jurisdictions, continues to create the potential for an unpredictable judgment in any given lawsuit. These lawsuits are in various stages of development, and future facts and circumstances could result in management changing its conclusions. It is possible that, if the defenses in these lawsuits are not successful, and the judgments are greater than management can anticipate, the resulting liability could have a material impact on our consolidated financial position, liquidity or results of operations. With respect to the existing litigation, management currently believes that the possibility of a material judgment adverse to American National is remote and no estimate of range can be made for loss contingencies that are at least reasonably possible but not accrued.
