Summary of Significant Accounting Policies and Practices	'
	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 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.
	Investments
	Investment securities – Bonds classified as held-to-maturity are carried at amortized cost. Bonds classified as available-for-sale are carried at fair value. Equity securities are classified as available-for-sale and carried at fair value. After-tax net unrealized gains or losses on available-for-sale securities are reflected in stockholders’ equity as a component of “Accumulated Other Comprehensive Income (Loss)” (“AOCI”).
	Mortgage loans on real estate are stated at unpaid principal balance, adjusted for any unamortized discount, deferred expenses, and allowances. Accretion of discounts is recorded using the effective yield method. Interest income, prepayment fees and accretion of discounts and origination fees are reported in “Net investment income” in the consolidated statements of operations. Interest income earned on impaired and non-impaired loans is accrued on the principal amount of the loan based on contractual interest rate. However, interest ceases to accrue for loans on which interest is more than 90 days past due, when the collection of interest is not probable or when a loan is in foreclosure. Income on past due loans is reported on a cash basis. When a loan becomes current, it is placed back into accrual status. Cash receipts on impaired loans are recorded as a reduction of principal, interest income, expense reimbursement or other manner in accordance with the loan agreement. Gains and losses from the sale of loans and changes in allowances are reported in “Realized investment gains (losses)” in the consolidated statements of operations.
	Each mortgage loan is evaluated quarterly and placed in a watchlist if events occur or circumstances exist that could indicate that American National will be unable to collect all amounts due according to the contractual terms. Additionally, loans with estimated collateral value less than their balance and loans with characteristics indicative of higher than normal credit risks are reviewed quarterly. All loans in the watchlist are analyzed individually for impairment. If a loan is concluded to be fully collectible, no loss allowance is recorded. Loans are considered impaired when, based upon current information and events, it is probable that all amounts due under the contractual terms of the loan will be uncollectible. A specific allowance for loan losses is established for the excess carrying value of the loan over either: (i) the present value of expected future cash flows discounted at the loan’s original effective interest rate, or (ii) the estimated fair value of the underlying collateral if the loan is in the process of foreclosure or otherwise collateral dependent. Allowances are also established on groups of loans with similar characteristics, such as property types, if based on experience, it is probable that a loss has occurred and the amount of the loss can be reasonably estimated. The allowance is reviewed quarterly to determine if it is adequate, or if a recovery of the asset is assured and the allowance can be reduced.

	Management believes the recorded allowance is adequate and is the best estimate of probable loan losses, including losses incurred at the reporting date but not identified by a specific loan. Management’s quarterly evaluation of the allowance is based on historical loan loss experience, known and inherent risks in the portfolio, adverse situations affecting the borrower’s ability to repay, the estimated value of the underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. Loans are charged off as uncollectible only when the loan is forgiven by a legal agreement. Prior to charging off a loan, an allowance is recorded based on the estimated recoverable amount. Upon forgiveness, both the allowance and the loan balance are reduced which results in no further gain or loss.
	Policy loans are carried at cost, which approximates fair value.
	Investment real estate including related improvements, are stated at cost less accumulated depreciation. Depreciation is provided on a straight-line basis over the estimated useful life of the asset (typically 15 to 50 years). Rental income is recognized on a straight-line basis over the term of the respective lease. American National classifies a property as held-for-sale if it commits to a plan to sell a property within one year and actively markets the property in its current condition for a price that is reasonable in comparison to its estimated fair value. Real estate held-for-sale is stated at the lower of depreciated cost or estimated fair value less expected disposition costs, and is not depreciated while it is classified as held-for-sale. American National periodically reviews its investment real estate for impairment and tests properties for recoverability whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable and the carrying value of the property exceeds its estimated fair value. Properties whose carrying values are greater than their undiscounted cash flows are written down to their estimated fair value, with the impairment loss included in “Realized investment gains (losses)” in the consolidated statements of operations. Impairment losses are based upon the estimated fair value of real estate, which is generally computed using the present value of expected future cash flows from the real estate discounted at a rate commensurate with the underlying risks as well as other appraisal methods. Real estate acquired upon foreclosure is recorded at the lower of its cost, or its estimated fair value at the date of foreclosure.
	Real Estate Joint Ventures and Other Limited Partnership Interests—American National uses the equity method of accounting for its investments in real estate joint ventures and other limited partnership interests in which it has more than a minor interest or influence over the investee’s operations, but it does not have a controlling interest and is not the primary beneficiary. These investments are reported as “Investments in unconsolidated affiliates” in the consolidated statements of financial position. For certain joint ventures, American National records its share of earnings using a lag methodology of one to three months for all instances where timely financial information is not available and the contractual right does not exist to receive such financial information. In addition to the investees’ regular impairment analysis of its underlying investments, American National routinely evaluates its investments in those investees for impairments. American National considers financial and other information provided by the investee, other known information and inherent risks in the underlying investments, as well as future capital commitments, in determining whether impairment has occurred. When an impairment is deemed to have occurred at the joint venture level, American National recognizes its share within “Equity in earnings (losses) of unconsolidated affiliates” to record the investment at its fair value. When an impairment results from American National’s separate analysis, an adjustment is made through “Realized investment gains (losses)” to record the investment at its fair value.
	Short-term investments comprised of commercial paper, are carried at amortized cost, which approximates fair value.
	Other invested assets comprised primarily of tax credit partnerships, CAPCO investments and mineral rights, are carried at cost, less allowance for depletion, where applicable. Other invested assets also include equity-indexed options which are carried at fair value. Impairments for other invested assets are considered on an individual basis.
	Impairments—American National evaluates all fixed maturity securities with unrealized losses on a quarterly basis to determine if the creditworthiness of any of those securities has deteriorated to a point where its carrying value will not be realized at maturity. For fixed maturity securities where management believes that the carrying value will not be realized, an other-than-temporary impairment (“OTTI”) loss is recorded. At December 31, 2013, the unrealized losses on fixed maturity securities that were not other-than-temporarily impaired were the result of credit spread widening. There were no delinquent coupon payments attributed to these securities at December 31, 2013.

	For all fixed maturity securities in unrealized loss positions which American National does not intend to sell and for which it is not more-likely-than-not that it will be required to sell before its anticipated recovery, American National assesses whether the amortized cost basis of securities will be recovered by comparing the net present value of the expected cash flows from those securities with its amortized cost basis. Management estimates the expected cash flows using historical experience information as well as market observable data, such as industry analyst reports and forecasts, sector credit ratings and other data relevant to the collectibility of a security. The net present value of the expected cash flows from fixed maturity securities is calculated by discounting management’s best estimate of expected cash flows from those securities at the effective interest rate implicit in the fixed maturity security when acquired. If the net present value of the expected cash flows is less than the amortized cost of the fixed maturity securities, an OTTI has occurred in the form of a credit loss. The credit loss is recognized in earnings in the amount of excess amortized cost over the net present value of the expected cash flows from the fixed maturity securities. If the fair value of the fixed maturity securities is less than the net present value of its expected cash flows at the impairment measurement date, a non-credit loss exists which is recorded in other comprehensive income (loss) for the difference between the fair value and the net present value of the expected cash flows.
	After the recognition of an OTTI, fixed maturity securities are accounted for as if they had been purchased on the OTTI measurement date, with a cost basis equal to their previous amortized cost less the related OTTI losses recognized in earnings. The new cost basis of an other-than-temporarily impaired security is not adjusted for subsequent increases in estimated fair value. Should there be a significant increase in the estimate of cash flows expected to be collected from previously impaired fixed maturity securities, the increase would be accounted for prospectively by accreting it as interest income over its remaining life.
	American National evaluates all equity securities in unrealized loss positions on a quarterly basis and recognizes an OTTI loss on those where a market price recovery is not expected in a reasonable period of time. All equity securities with unrealized losses are also evaluated for credit quality. OTTI is recognized if management believes the carrying value of securities will not be realized, regardless of the length of time that they have had an unrealized loss.
	Derivative instruments are purchased as hedges of a recognized asset or liability, and are recorded on the consolidated statements of financial position at fair value. The change in fair value of derivative assets and liabilities is reported in the consolidated statements of operations as “Net investment income” and “Interest credited to policyholder account balances,” respectively. American National does not apply hedge accounting treatment to its derivative instruments. Derivative instruments held at December 31, 2013 and 2012 were immaterial to the consolidated financial statements.
	Cash and cash equivalents
	Cash and cash equivalents include cash on-hand and in banks plus amounts invested in money market funds and are reported as “Cash and cash equivalents” in the consolidated statements of financial position.
	Property and equipment
	These assets consist of buildings occupied by American National, data processing equipment, and furniture and equipment, which are carried at cost, less accumulated depreciation. Depreciation is calculated using straight-line and accelerated methods over the estimated useful lives of the assets (3 to 50 years).

	Insurance specific assets and liabilities
	Deferred policy acquisition costs (“DAC”) are the capitalized costs related directly to the successful acquisition of new or renewal insurance contracts. Significant costs are incurred to acquire insurance and annuity contracts, including commissions and certain underwriting, policy issuance and processing expenses.
	DAC on traditional life and health products is amortized with interest over the anticipated premium-paying period of the related policies, in proportion to the ratio of annual premium revenue expected to be received over the life of the policies. Expected premium revenue is estimated by using the same mortality, morbidity and withdrawal assumptions used in computing liabilities for future policy benefits. DAC is reduced by a provision for possible inflation of maintenance and settlement expenses determined by means of grading interest rates.
	DAC on universal life, limited-pay and investment-type contracts is amortized as a level percentage of the present value of anticipated gross profits from investment yields, mortality, and surrender charges. The effect of the realization of unrealized gains (losses) on DAC is recognized within AOCI in the consolidated statements of financial position as of the reporting date. A change in interest rates could have a significant impact on DAC calculated for these contracts.
	DAC associated with property and casualty business is amortized over the coverage period of the related policies, in relation to premium revenue.
	For short-duration and long-duration contracts, DAC is grouped consistent with the manner in which insurance contracts are acquired, serviced and measured for profitability and is reviewed for recoverability based on the profitability of the underlying insurance contracts. Investment income is not anticipated in assessing the recoverability of DAC for short-duration contracts.
	Liabilities for future policy benefits for traditional products have been provided on a net level premium method based on estimated investment yields, withdrawals, mortality, and other assumptions that were appropriate at the time policies were issued. Estimates used are based on historical experience, adjusted for possible adverse deviation. These estimates are periodically reviewed and compared with actual experience. When it is determined that future expected experience differs significantly from existing assumptions, the estimates are revised for current and future issues.
	Policyholders’ account balances represent the contract value that has accrued to the benefit of the policyholders related to universal-life, limited-pay and investments-type contracts. These are generally equal to the accumulated deposits, plus interest credited, reduced by withdrawals, payouts, and accumulated policyholder assessments.
	Reserves for claims and claim adjustment expenses (“CAE”) are established to provide for the estimated costs of paying claims. These reserves include estimates for both case reserves and incurred but not reported (“IBNR”) claim reserves. Case reserves include the liability for reported but unpaid claims. IBNR reserves include a provision for potential development on case reserves, losses on claims currently closed which may reopen in the future, as well as incurred but not reported claims. These reserves also include an estimate of the expense associated with settling claims, including legal and other fees and the general expenses of administering the claims adjustment process.
	Reinsurance—Reinsurance recoverables are estimated amounts due to American National from reinsurers related to paid and unpaid ceded claims and CAE and are presented net of a reserve for non-recoverability. Recoveries on our gross ultimate losses are generally determined by a review of individual large claims as well as by estimating the ceded portion of IBNR using assumed distribution of loss by percentage retained. The most significant assumption used is the average size of the individual losses for those claims that have occurred but have not yet been recorded. The ultimate amount of the reinsurance ceded recoverable is unknown until all losses are settled.

	Premiums, benefits, claims incurred and expenses
	Traditional ordinary life and health—Life and accident and health premiums are recognized as revenue when due. Benefits and expenses are associated with earned premiums to result in recognition of profits over the term of the insurance contracts.
	Annuities—Premiums received on limited-pay and supplemental annuity contracts involving a significant life contingency are recognized as revenue when due. Deferred annuity premiums are recorded as deposits rather than recognized as revenue. Revenues from deferred annuity contracts are principally surrender charges and, in the case of variable annuities, administrative fees assessed to contractholders.
	Universal life and single premium whole life revenues represent amounts assessed to policyholders. Included in revenue are mortality charges, surrender charges actually paid and earned policy service fees. Amounts included in expenses are benefits in excess of account balances returned to policyholders.
	Property and casualty premiums are recognized as revenue proportionately over the contract period, net of reinsurance ceded. Claims incurred consist of actual claims and CAE paid and the change in reserves, net of reinsurance received and recoverable.
	Participating insurance policies
	Participating business comprised approximately 8.1% of the life insurance in-force at December 31, 2013 and 11.7% of life premiums in 2013. Of the total participating business, 78.1% was written by Farm Family Life Insurance Company (“Farm Family Life”). For the participating business excluding Farm Family Life, the allocation of dividends to participating policyowners is based upon a comparison of experienced rates of mortality, interest and expenses, as determined periodically for representative plans of insurance, issue ages and policy durations, with the corresponding rates assumed in the calculation of premiums.
	For the Farm Family Life participating business, profits earned on participating business are reserved for the payment of dividends to policyholders, except for the stockholders’ share of profits on participating policies, which is limited to the greater of 10% of the profit on participating business, or 50 cents per thousand dollars of the face amount of participating life insurance in-force. Participating policyholders’ interest includes the accumulated net income from participating policies reserved for payment to such policyholders in the form of dividends (less net income allocated to stockholders as indicated above) as well as a pro rata portion of unrealized investment gains (losses), net of tax.
	Federal income taxes
	American National Insurance Company and its eligible subsidiaries file a consolidated life and non-life federal income tax return. Certain subsidiaries that are consolidated for financial reporting are not eligible to be included in the consolidated federal income tax return; accordingly, they file separate returns.
	Deferred federal income tax assets and liabilities have been recognized to reflect the future tax consequences attributable to differences between the financial statement amounts of assets and liabilities and their respective tax bases. Deferred taxes are measured using enacted tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled.
	American National recognizes tax benefits on uncertain tax positions if it is “more-likely-than-not” the position based on its technical merits will be sustained by taxing authorities. American National recognizes the largest benefit that is greater than 50% likely of being ultimately realized upon settlement. Tax benefits not meeting the “more-likely-than-not” threshold, if applicable, are included with “Other liabilities” in the consolidated statements of financial position.
	Interest and penalties assessed, if applicable, are classified as “Other operating expenses” in the consolidated statements of operations.

	Pension and postretirement benefit plans
	The pension and postretirement benefit obligations and costs are calculated using concepts in accordance with GAAP. The discount rate and the expected return on plan assets are important elements of expense and/or liability measurement, and these key assumptions are evaluated annually. Other assumptions involve demographic factors such as retirement age, mortality, turnover and compensation.
	American National uses a discount rate to determine the present value of future benefits on the measurement date. The guideline for setting this rate is a high-quality long-term corporate bond rate. To determine the expected long-term rate of return on plan assets, a building-block method is used. The expected rate of return on each asset is broken down into three components: inflation, the real risk-free rate of return (i.e., the long-term estimate of future returns on default-free U.S. government securities), and the risk premium for each asset class (i.e., the expected return in excess of the risk-free rate). Using this approach, the calculated return will fluctuate from year to year; however, it is American National’s policy to hold this long-term assumption relatively constant.
	Stock-based compensation
	Stock Appreciation Rights—The measurement of the stock appreciation rights (“SARs”) liability and compensation cost is based on the fair value of the grants and are remeasured each reporting period through the settlement date. The fair value of the SAR’s is calculated using the Black-Scholes-Merton option-pricing model. The key assumptions used in the model include: the grant date and remeasurement date stock prices, expected life of the SARs and the risk-free rate of return. The compensation liability related to the SAR award is included in “Other liabilities” in the consolidated statements of financial position.
	Restricted Stock—The measurement of the equity and compensation cost of restricted stock (“RS”) is based on the fair value of the underlying stock at grant date. The compensation cost accrued is included in “Additional paid-in capital” in the consolidated statements of financial position.
	Restricted Stock Units—Effective December 31, 2012, American National’s Board Compensation Committee modified the settlement provision within the outstanding restricted stock units (“RSU”) providing the recipients of the awards option to settle vested RSUs in either cash or American National common stock. The modification in the settlement provision changed the RSU classification from an equity to a liability award. After the modification, the liability has been remeasured each reporting period through the vesting date and will be adjusted for the changes in fair value. The compensation liability related to the RSUs is included in “Other Liabilities” in the consolidated statement of financial position.
	Separate account assets and liabilities
	Separate account assets and liabilities are funds intended to meet the investment objectives of contract holders who bear the investment risk. Investment income and investment gains and losses from these separate funds accrue to the benefit of the contract holders. Separate accounts are established in conformity with insurance laws and are not chargeable with liabilities that arise from any other business of American National. American National reports separately, as assets and liabilities, investments held in separate accounts and liabilities of the separate accounts if (i) such separate accounts are legally recognized; (ii) assets supporting the contract liabilities are legally insulated from American National’s general account liabilities; (iii) investments are directed by the contract holder; and (iv) all investment performance, net of contract fees and assessments, is passed through to the contract holder. The assets of these accounts are carried at fair value. Deposits, net investment income and realized investment gains and losses for these accounts are excluded from revenues, and related liability increases are excluded from benefits and expenses in the consolidated financial statements.
	Litigation contingencies
	American National reviews existing litigation matters and potential litigation items with counsel quarterly to determine if any adjustments to liabilities for possible losses are necessary. Reserves for losses are established whenever they are probable and estimable based on the best estimate of the probable loss. If no one estimate within the range of possible losses is more probable than any other, a reserve is recorded based on the lowest amount of the range.

	3. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
	Adoption of New Accounting Standards—The Financial Accounting Standards Board (“FASB”) issued the following accounting guidance relevant to American National, including technical amendments and corrections to make the accounting standards easier to understand and fair value measurement easier to apply. Each became effective for American National on January 1, 2013, and unless stated otherwise, did not have a material effect on the consolidated financial statements:
	Amended guidance for derecognition of an in substance real estate subsidiary. The amendment clarifies that when a reporting entity ceases to have a controlling financial interest in a subsidiary that is in substance real estate because of a default on the subsidiary’s nonrecourse debt secured by the real estate, the reporting entity should apply the guidance for real estate sales when evaluating the subsidiary for deconsolidation.
	Guidance that amends the disclosures about offsetting assets and liabilities. The new guidance requires disclosures of both gross and net information about offsetting and related arrangements. Subsequently, amendments were issued to clarify the scope of this guidance covering only those derivatives that are either offsets in accordance with the right of setoff conditions, the balance sheet netting criteria or subject to an enforceable master netting arrangement or similar agreement.
	Amended guidance on presentation of AOCI. The amendments require disclosures about the amounts reclassified out of AOCI by component. In addition, an entity is required to present, either on the face of the statement of operations or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts.
	Future Adoption of New Accounting Standards—The FASB issued the following significant accounting guidance relevant to American National. Each became effective for American National on January 1, 2014 and unless stated otherwise, did not have a material effect on the consolidated financial statements:
	Guidance addressing questions on the recognition and classification of fees mandated by the Patient Protection and Affordable Care Act on health insurers’ financial statements. The guidance specifies that the liability for the fee should be recorded in full once the entity provides qualifying health insurance in the applicable calendar year. The corresponding deferred cost is then amortized to expense using a straight-line method of allocation unless another method better allocates the fee over the calendar year that it is payable.
	Amended guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the guidance is fixed at the reporting date. The amended guidance requires the entity to measure obligations resulting from joint and several liability arrangements as the sum of the amount the reporting entity agreed with co-obligors to pay and any additional amounts it expects to pay on behalf of one or more co-obligors.
	Guidance that allows investors to elect the use of proportional amortization method to account for investments in qualified affordable housing projects, if certain conditions are met. The new guidance replaces the effective yield method and allows an investor to amortize the cost of its investment, in proportion to the tax credits and other tax benefits it receives, to income tax expense. The guidance requires new disclosure for all investors for all investments in qualified affordable housing projects, regardless of the accounting method used for those investments.

Gross realized losses			(3,413	)		(2,009	)		(1,600	)
All gains and losses for securities sold throughout the year were determined using specific identification of the securities sold. During 2013 and 2012, bonds with a carrying value of $13,492,000 and $62,500,000, respectively, were transferred from held-to-maturity to available-for-sale after a significant deterioration in the issuers’ creditworthiness became evident. An unrealized loss of $236,000 was established at the time of the transfer in 2013, while an other-than-temporary impairment of $11,358,000 was recorded in 2012 following the transfers at fair value.
In accordance with various regulations, American National had bonds on deposit with regulating authorities with a carrying value of $50,471,000 and $50,027,000 at December 31, 2013 and 2012, respectively. In addition, American National has pledged bonds in connection with agreements and transactions, such as financing and reinsurance agreements. The carrying value of bonds pledged was $68,125,000 and $73,176,000 at December 31, 2013 and 2012, respectively.

As of December 31, 2013, the securities with unrealized losses were not deemed to be other-than-temporarily impaired, including those with the duration of the unrealized losses exceeding one year. American National has the ability and intent to hold those securities until a market price recovery or maturity. Further, it is not more-likely-than-not that American National will be required to sell them prior to recovery, and recovery is expected in a reasonable period of time. It is possible an issuer’s financial circumstances may be different in the future, which may lead to a different impairment conclusion in future periods.

Allowance for Credit Losses
Loans not evaluated individually for collectibility are segregated by property-type and location, and allowance factors are applied. These factors are developed annually and reviewed quarterly based on our 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.

Troubled Debt Restructurings
American National has granted concessions to mortgage loan borrowers related to their ability to pay the loans which are classified as troubled debt restructurings. 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 recovery assessment.
The number of mortgage loans and recorded investment in troubled debt restructuring are as follows:


		Years ended December 31,
		2013											2012
		Number of				Recorded				Recorded			Number of			Recorded			Recorded
		contracts				investment pre-				investment post			contracts			investment pre-			investment post

Total			2			$	9,171			$	9,171			4		$	17,342		$	17,342

There are no commitments to lend additional funds to debtors whose loans have been modified in troubled debt restructuring, and there have been no defaults on modified loans during the period.

	American National and its wholly-owned subsidiaries regularly invest in real estate partnerships and joint ventures. 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 2013 or 2012.
	The assets and liabilities relating to the VIEs included in the consolidated financial statements are as follows (in thousands):

	Total liabilities of consolidated VIEs	$	120,529		$	170,031


	The notes payable in the consolidated statements of financial position pertain to the borrowings of the consolidated VIEs. The liability of American National Insurance Company relating to notes payable of the consolidated VIEs is limited to the amount of its direct or indirect investment in the respective ventures, which totaled $12,782,000 and $18,063,000 at December 31, 2013 and 2012, respectively. The current portion of notes payable was $3,199,000 and $50,884,000 at December 31, 2013 and 2012, respectively. The average interest rate on the current portion of the notes payable was 4.25% during 2013. The total long-term portion of notes payable consists of three notes with the following interest rates: 4.0%, and adjusted LIBOR plus LIBOR margin. Of the long-term notes payable, $9,375,000 will mature in 2016, with the remainder maturing beyond 5 years.
	For other VIEs in which American National is a partner, it is not the primary beneficiary and these entities were not consolidated, as the major decisions that most significantly impact the economic activities of the VIE require unanimous consent of all partners. The following table presents the carrying amount and maximum exposure to loss relating to unconsolidated VIEs (in thousands):


		December 31,

	As of December 31, 2013, a real estate investment with a carrying value of $15,086,000 was classified as held for sale as of after an offer to purchase the property was received and it is likely the transaction will occur in 2014. The property is carried at fair value less estimated selling cost, which resulted in a $300,000 loss.

	Summary

	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability. 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—American National utilizes a pricing service to estimate fair value measurements. The estimates of fair value for most fixed maturity securities, including municipal bonds, provided by the pricing service are disclosed as Level 2 measurements as the estimates are based on observable market information rather than market quotes.



	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 markets, benchmark securities, bids, offers, reference data, and economic events. The extent of the use of each market input depends on the asset class and the market conditions. Depending on the security, the priority of the use of inputs may change or some market inputs may not be relevant. For some securities, additional inputs may be necessary.

	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.

	The pricing of certain commercial mortgage-backed securities use discounted cash flow models, and these securities are classified as Level 3 measurements. These models include significant non-observable inputs including an internally determined credit rating of the security and an externally provided credit spread. At December 31, 2013 and 2012, the modeled discount rate ranges from 5.9% to 6.0%.

	For securities priced using a quote from an independent broker, such as the equity options and certain fixed maturity securities, American National uses a market-based fair value analysis to validate the reasonableness of prices received from an independent broker. Price variances above a certain threshold are analyzed further to determine if any pricing issue exists. This analysis is performed quarterly.

	Equity Securities—For publicly-traded equity securities, prices are received from a nationally recognized pricing service that are based on observable market transactions, and these securities are classified as Level 1 measurements. For certain preferred stock, current market quotes in active markets are unavailable. In these instances, an estimate of fair value is received from the pricing service. The service utilizes similar methodologies to price preferred stocks as it does for fixed maturity securities. These estimates are disclosed as Level 2 measurements. American National tests the accuracy of the information provided by reference to other services regularly.

Mortgage Loans—The fair value of mortgage loans is estimated using discounted cash flow analyses on a loan by loan basis by applying a discount rate to expected cash flows from future installment and balloon payments. The discount rate takes into account general market trends and specific credit risk trends for the individual loan. Factors used to arrive at the discount rate include inputs from spreads based on U.S. Treasury notes and the loan’s credit quality, region, property type, lien priority, payment type and current status.

Embedded Derivative—The embedded derivative liability for equity-indexed contracts is measured at fair value and is recalculated each reporting period using equity option pricing models. To validate the assumptions used to price the embedded derivative liability, American National measures and compares embedded derivative returns against the returns of equity options held to hedge the liability cash flows.



The significant unobservable input used to calculate the fair value of the embedded derivatives is equity option implied volatility. An increase in implied volatility will result in an increase in the value of the equity-indexed embedded derivatives, all other things being equal. At December 31, 2013 and 2012, the one year implied volatility used to estimate embedded derivative value was 15.0% and 18.1%, respectively.

Other Financial Instruments—Other financial instruments classified as Level 3 measurements, as there is little or no market activity, are as follows:

Policy loans—The carrying value of policy loans is the outstanding balance plus any accrued interest. Due to the collateralized nature of policy loans that it cannot be separated from the policy contract and the unpredictable timing of repayments and 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 to current rates offered 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.

There were no transfers between Level 1 and Level 2 fair value hierarchies. The transfers into Level 3 were the result of existing securities no longer being priced by the third-party pricing service at the end of the period. American National’s valuation of these securities involves judgment regarding assumptions market participants would use including quotes from independent brokers. The transfers out of Level 3 were securities being priced by a 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.

	Effective January 1, 2012, American National retrospectively adopted a new accounting guidance for deferring costs associated with acquiring or renewing insurance contracts. The amended accounting guidance limits the deferrable cost to those incremental direct costs associated with the successful acquisition or renewal of insurance contracts. It also specifies that advertising costs should be deferred only if the capitalization criteria for direct-response advertising are met. Upon adoption, the DAC asset was reduced by $34,260,000 as a result of acquisition costs previously deferred that are no longer eligible for deferral under the new guidance.

	Commissions comprise the majority of the additions to deferred policy acquisition costs for each year.

Liability for Future Policy Benefits and Policyholder Account Balances	'
	11. LIABILITY FOR FUTURE POLICY BENEFITS AND POLICYHOLDER ACCOUNT BALANCES
	American National establishes liabilities for amounts payable under insurance and annuity policies. Generally, amounts are payable over an extended period of time and related liabilities are calculated as the present value of expected benefit payments reduced by the present value of expected premiums. Such liabilities are established on a block of business based on methods and underlying assumptions in accordance with GAAP and applicable actuarial standards. Principal assumptions used in the establishment of liabilities for future policy benefits are mortality, morbidity, policy lapse, renewal, retirement, disability incidence, disability termination, investment return, inflation, expenses, and other contingent events as appropriate to the respective product type.
	Future policy benefits for non-participating traditional life insurance are equal to the aggregate of the present value of expected benefit payments and related expenses less the present value of expected net premiums. Assumptions as to mortality and persistency are based upon American National’s experience when the basis of the liability is established. Interest rates for the aggregate future policy benefit liabilities range from 3.0% to 8.0%.
	Future policy benefit liabilities for participating traditional life insurance are equal to the aggregate of (i) net level premium reserves for death and endowment policy benefits (calculated based upon the non-forfeiture interest rate, ranging from 2.5% to 5.5%) and mortality rates guaranteed in calculating the cash surrender values described in such contracts; and (ii) the liability for terminal dividends.

	Future policy benefit liabilities for individual fixed deferred annuities after annuitization and single premium immediate annuities are equal to the present value of expected future payments. The interest rate used in establishing such liabilities range from 3.0% to 5.6% for all policies in-force.
	Future policy benefit liabilities for non-medical health insurance are calculated using the net level premium method and assumptions as to future morbidity, withdrawals and interest, which provide a margin for adverse deviation. Interest rates used in establishing such liabilities range from 3.5% to 8.0%.
	Future policy benefit liabilities for disabled lives are estimated using the present value of benefits method and experience assumptions as to claim terminations, expenses and interest. Interest rates used in establishing such liabilities range from 3.0% to 4.5%.
	Liabilities for universal life secondary guarantees and paid-up guarantees are determined by estimating the expected value of death benefits payable when the account balance is projected to be zero and recognizing those benefits ratably over the accumulation period based on total expected assessments. American National regularly evaluates estimates used and adjusts the additional liability balances with a related charge or credit to benefit expense, if actual experience or other evidence suggests that earlier assumptions should be revised. The assumptions used in estimating the secondary and paid-up guarantee liabilities are consistent with those used for amortizing DAC, and are thus subject to the same variability and risk. The assumptions of investment performance and volatility for variable products are consistent with historical Standard & Poor’s experience. The benefits used in calculating the liabilities are based on the average benefits payable over a range of scenarios.
	American National periodically reviews its estimates of actuarial liabilities for future policy benefits and compares them with its actual experience. Differences between actual experience and the assumptions used in pricing these policies, guarantees and riders and in the establishment of the related liabilities result in variances in profit and could result in losses. The effects of changes in such estimated liabilities are included in the results of operations in the period in which the changes occur.
	Policyholder account balances relate to investment-type contracts and universal life-type policies. Investment-type contracts principally include traditional individual fixed annuities in the accumulation phase and non-variable group annuity contracts. Policyholder account balances are equal to (i) policy account values, which consist of an accumulation of gross premium payments; (ii) credited interest, ranging from 1.0% to 8.0% (some annuities have enhanced first year crediting rates ranging from 1.0% to 7.0%), less expenses, mortality charges, and withdrawals; and (iii) fair value adjustments.

	The liability for unpaid claims and claim adjustment expenses (“claims”) for accident and health, and property and casualty insurance is included in the “Policy and contract claims” in the consolidated statements of financial position and represents the amount estimated for claims that have been reported but not settled and IBNR claims. 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, reduced for 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.

Estimates for ultimate incurred claims attributable to insured events of prior years decreased by approximately $46,872,000 in 2013, $48,688,000 in 2012, and $82,523,000 in 2011.

	13. REINSURANCE

	American National reinsures portions of certain life insurance policies to provide a greater diversification of risk and manage exposure on larger risks. For the issue ages zero to 65, the maximum amount that would be retained by one life insurance company (American National) would be $1,500,000 individual life, $250,000 individual accidental death, $100,000 group life, and $125,000 credit life (total $1,975,000). If individual, group and credit insurance were all in force at the same time, the maximum risk on any one life could be $3,225,000. For the issue ages 66 and over, the maximum amount that would be retained by one life insurance company (American National) would be $700,000 individual life, $250,000 individual accidental death, $100,000 group life, and $125,000 credit life (total $1,175,000). If individual, group and credit insurance were all in force at the same time, the maximum risk on any one life could be $2,425,000.

	For the Property and Casualty segment, American National retains the first $1,000,000 of loss per risk. Reinsurance then covers the next $5,000,000 of property and liability losses per risk. Additional excess property per risk coverage is purchased to cover risks up to $15,000,000, and excess casualty clash coverage is maintained to cover losses up to $50,000,000. Excess casualty clash covers losses incurred as a result of one casualty event involving multiple policies, excess policy limits, and excess contractual obligations. Facultative reinsurance cover is purchased for individual risks attaching at $15,000,000, as needed. Corporate catastrophe coverage is also in place for losses up to a $500,000,000 event. Catastrophe aggregate reinsurance coverage is also purchased. This cover provides for $30,000,000 of coverage after $90,000,000 of aggregated catastrophe losses has been reached. The first $10,000,000 of each catastrophe loss contributes to the $90,000,000 aggregation of losses. The catastrophe aggregate reinsurance coverage for 2013 was placed at 100%.

	American National remains primarily liable with respect to any reinsurance ceded, and would bear the entire loss if the reinsurer were to be unable to meet their obligations under any reinsurance treaties. American National had amounts recoverable from reinsurers of $414,743,000 and $418,743,000 at December 31, 2013 and 2012, respectively. None of the amount outstanding at December 31, 2013 is the subject of litigation or is in dispute with the reinsurers involved. Management believes the unfavorable resolution of any dispute that may arise would not have a material impact on American National’s consolidated financial statements.

	The amounts in the consolidated financial statements include the impact of reinsurance. Information regarding the effect of reinsurance is shown below (in thousands):

	Total net deferred tax assets (liabilities)	$	(220,428	)	$	(92,150	)


	Management believes that a sufficient level of taxable income will be achieved over time to utilize the deferred tax assets in the consolidated federal tax return; therefore, no valuation allowance was recorded as of December 31, 2013 and 2012. However, if not utilized beforehand, approximately $10,843,000 in ordinary loss tax carryforwards will expire on December 31, 2033.

	The statute of limitations for the examination of federal income tax returns by the Internal Revenue Service for years 2006 to 2012 either has been extended or has not expired. 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 was established, and no interest expense was incurred for 2013, 2012 or 2011, relating to uncertain tax positions. 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.

	Stock-based compensation

	American National has one stock-based compensation plan, which allows for grants of Non-Qualified Stock Options, Stock Appreciation Rights (“SAR”), Restricted Stock (“RS”) Awards, Restricted Stock Units (“RSU”), Performance Awards, Incentive Awards or any combination thereof. This plan is administered by the American National Board Compensation Committee. The Board Compensation Committee makes incentive awards under this plan to our executives after meeting established performance objectives. All awards are subject to review and approval by the committee and the Board of Directors, both at the time of setting applicable performance objectives and at the time of payment of the awards. The number of shares available for grants under the plan cannot exceed 2,900,000 shares, and no more than 200,000 shares may be granted to any one individual in any calendar year. Grants are made to certain officers and directors as compensation and to align their interests with those of other shareholders.

The SARs give the holder the right to cash compensation based on the difference between the stock price on the grant date and the stock price on the exercise date. The SARs vest at a rate of 20% per year for five years and expire five years after vesting.

Effective December 31, 2012, the settlement provision within outstanding RSU awards was modified to allow the recipient of the awards to settle the vested RSUs in either cash or American National’s common stock. This change in the settlement provision is expected to apply to all future issuance of RSU awards. Prior to the modification, vested RSUs were converted to American National’s common stock on a one-for-one basis. This modification changes the award classification from an equity to a liability award. At the date of modification, American National recorded a liability of $7,974,000 with a corresponding reduction in additional paid-in capital. The liability will be remeasured and adjusted for changes in the fair value each reporting period through the vesting date. RSUs generally vest after a three-year graded vesting requirement. Certain awards vest over a shorter period as a result of retirement provisions. The modification, which was applied consistently to all participants, resulted in an incremental cost of $5,232,000 and $0 for the years ended December 31, 2013 and 2012, respectively.

RS Awards entitle the participant to full dividend and voting rights. Each award 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 these awards feature a graded vesting schedule in the case of the retirement of an award holder. Restricted stock for 350,334 shares has been granted at an exercise price of zero, of which 190,667 shares are unvested.

Earnings per share

Basic earnings per share were calculated using a weighted average number of shares outstanding. The Restricted Stock awards and units resulted in diluted earnings per share as follows (in thousands, except share-related data):

Diluted earnings per share			9.97				7.11				7.14



Statutory Capital and Surplus

Risk Based Capital (“RBC”) requirements are measures insurance regulators use to evaluate the capital adequacy of American National Insurance Company and its insurance subsidiaries. RBC is calculated using formulas applied to certain financial balances and activities that consider, among other things, risks related to the type and quality of the invested assets, insurance risks associated with an insurer’s 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 December 31, 2013 and 2012, American National Insurance Company’s statutory capital and surplus was $2,667,589,000 and $2,260,268,000, respectively. Additionally, each of the insurance subsidiaries had statutory capital and surplus at December 31, 2013 and 2012, substantially above each individual subsidiary’s authorized control level RBC.

American National’s 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 for a Texas domiciled insurer, the statutory capital and surplus of the Texas domiciled insurer. This permitted practice increases the statutory capital and surplus of both American National Insurance Company and the Missouri domiciled insurance subsidiary by $58,207,000 and $54,234,000 at December 31, 2013 and 2012, respectively. Additionally, the statutory capital and surplus of both American National Insurance Company and the Missouri domiciled insurance subsidiary would have remained substantially above the company action level RBC had it not used the permitted practice.

The statutory capital and surplus and net income (loss) of our life and property and casualty insurance entities in accordance with statutory accounting practices are shown below (in thousands):



		December 31,
		2013				2012

Property and casualty insurance entities			61,754				43,454				31,602



Dividends

American National Insurance Company’s payment of dividends to stockholders is restricted by statutory regulations. 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 prior year statutory net income from operations on an annual, non-cumulative basis, or 10% of prior year statutory surplus. Under Texas insurance law, American National Insurance Company is permitted to pay total dividends of $266,786,000 during 2014, without prior approval of the Texas Department of Insurance. 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 that is 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 December 31, 2013 and 2012.

American National Insurance Company and its subsidiaries exercise significant 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 $6,007,000 and $4,741,000 at December 31, 2013 and 2012, respectively.

During 2012 and 2011, American National increased its ownership interest with a consolidated joint venture. The effect of the change in ownership interest of American National is shown below (in thousands):

	17. SEGMENT INFORMATION

	Management organizes the business into five operating segments:


		•		Life—markets whole, term, universal, indexed and variable life insurance on a national basis primarily through career and multiple-line agents, as well as independent agents and direct marketing channels.


		•		Annuity—offers fixed, indexed, and variable annuity products. These products are primarily sold through independent agents, brokers, and financial institutions, along with multiple-line and career agents.


		•		Health—primary lines of business are Medicare supplement, stop loss, other supplemental health products and credit disability insurance. Health products are typically distributed through independent agents and managing general underwriters.


		•		Property and Casualty—writes personal, agricultural and commercial coverages and credit-related property insurance. These products are primarily sold through multiple-line and independent agents.


		•		Corporate and Other—consists of net investment income from investments not allocated to the insurance segments and revenues from non-insurance operations.



	The accounting policies of the segments are the same as those described in Note 2. All revenue and expense amounts specifically attributable to policy transactions are recorded directly to the appropriate operating segment. Revenues and expenses not specifically attributable to policy transactions are allocated to each segment as follows:


		•		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 within the respective operating segments.

	The following summarizes results of operations by operating segments (in thousands):

	18. PENSION AND POSTRETIREMENT BENEFITS
	Pension benefits
	On October 31, 2013, American National adopted certain amendments to freeze all of its remaining unfrozen defined benefit pension plans as of December 31, 2013. Prior to the plan amendments, American National had a qualified defined benefit pension plan covering virtually all employees and two non-qualified defined benefit pension plans covering executives. Effective December 31, 2013, benefits accrued through these plans will no longer include additional years of service credit or future salary increase credit, and no new participants will be added to the plans. Benefits earned by eligible employees prior to the effective date of the plan amendments will not be affected. The plan amendments did not result in any curtailment gain or loss.
	The tax-qualified plan has three separate noncontributory programs. One of the programs covers Career Sales and Service Division agents and managers. The other two programs cover salaried and management employees and corporate clerical employees subject to a collective bargaining agreement. The program covering salaried and management employees provides pension benefits that are based on years of service and the employee’s compensation during the five years before retirement. The programs covering hourly employees and agents generally provide benefits that are based on the employee’s career average earnings and years of service. The three non-tax-qualified pension plans cover key executive employees and restore benefits that would otherwise be curtailed by statutory limits on qualified plan benefits. In addition, American National also has one frozen, tax-qualified, defined-benefit pension plan covering employees of the Farm Family companies hired prior to January 1, 1997. Effective January 1, 1997, benefits through this plan were frozen, and no new participants have been added.

American National’s funding policy for the qualified pension plans is to make annual contributions to meet the minimum funding standards of ERISA. The unfunded plans will be funded out of general corporate assets when necessary. American National contributed $10,065,000, $48,531,000, and $34,547,000 to the qualified pension plan in 2013, 2012 and 2011, respectively. American National and its affiliates expect to contribute $10,700,000 to its qualified pension plan in 2014.

The investment policy for the retirement plan assets is designed to provide the highest return possible commensurate with sound and prudent underwriting practices. The investment diversification goals are to have investments in cash and cash equivalents as necessary for liquidity, debt securities up to 100% and equity securities up to 60% of the total invested plan assets. The amount invested in any particular investment is limited based on credit quality, and no single investment may at the time of purchase be more than 5% of the total invested assets.
The corporate debt securities category are investment grade bonds of U.S and foreign issuers denominated and payable in U.S. dollars from diverse industries, with a maturity of 1 to 30 years. Foreign bonds in the aggregate shall not exceed 20% of the bond portfolio. Residential mortgage-backed securities represents asset-backed securities with a maturity date 1 to 30 years with a rating of NAIC 1 or 2.
Equity portfolio managers have discretion to choose the degree of concentration in various issues and industry sectors for the equity securities. Permitted securities are those for which there is an active market providing liquidity for the specific security.
Commercial paper investments generally have a credit rating of A-2 Moody’s or P-2 by Standard & Poor’s with at least BBB rating on the issuer’s outstanding debt, or selected issuers with no outstanding debt.
Postretirement life and health benefits
American National provides certain health and dental benefits to a closed block of retirees and their dependents who met certain age and length of service requirements as of December 31, 1993. The primary retiree health benefit plan provides Medicare Supplemental and prescription drug benefits. The plan is contributory, with American National’s contribution limited to $40 per month for retirees and spouses with any additional contributions necessary, being made by the retirees.
The accrued postretirement benefit obligation, included in the liability for retirement benefits, was $5,050,000 and $6,018,000 at December 31, 2013 and 2012, respectively. These amounts were approximately equal to the unfunded accumulated postretirement benefit obligation. Since American National’s contributions to the cost of the retiree benefit plans are fixed, the health care cost trend rate will have no effect on the future expense or the accumulated postretirement benefit obligation. Under American National’s various group benefit plans for active employees, life insurance benefits are provided upon retirement for eligible participants who meet certain age and length of service requirements.

Savings plans
American National sponsors one defined contribution plan for all employees excluding those of the Farm Family companies, and an incentive savings plan for employees of the Farm Family companies. The defined contribution plan (401(k) plan) allows employees to contribute up to the maximum allowable amount as determined by the IRS. Prior to January 1, 2014, American National did not contribute to the defined contribution plan. Company contributions are made under the incentive savings plan for the Farm Family companies, with a discretionary portion based on the profits earned by the Farm Family companies. The expense associated with this plan was $1,900,000 for 2013, $1,700,000 for 2012, and $1,810,000 for 2011. Beginning in 2014, American National will provide retirement benefits for eligible employees using contributory defined contribution plans and will make company contribution as a percent of eligible employees’ pay and a matching contribution of each employees elected contribution.

	19. COMMITMENTS AND CONTINGENCIES

	Commitments

	American National and its subsidiaries lease insurance sales office space in various cities. The remaining long-term lease commitments at December 31, 2013, were approximately $1,760,000.

	American National had aggregate commitments at December 31, 2013, to purchase, expand or improve real estate, to fund fixed interest rate mortgage loans, and to purchase other invested assets of $513,773,000 of which $409,017,000 is expected to be funded in 2014. The remaining $104,756,000 will be funded in 2015 and beyond.

	In September 2013, American National renewed an existing $100,000,000 short-term variable rate borrowing facility containing a $55,000,000 sub-feature for the issuance of letters of credit. Borrowings under the facility are at the discretion of the lender and would be used only for funding working capital requirements. The combination of borrowings and outstanding letters of credit cannot exceed $100,000,000 at any time. As of December 31, 2013 and 2012, the outstanding letters of credit were $15,560,000 and $33,696,000, respectively, and there were no borrowings on this facility to meet liquidity requirements. This facility expires on September 30, 2014. American National expects it will be renewed on substantially equivalent terms upon expiration.

	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 the bank loan, American National would be obligated to pay off the loans. 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 December 31, 2013, was approximately $206,376,000, while the total cash values of the related life insurance policies was approximately $210,050,000.

	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’s 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.

	-1	Net investment income from fixed income assets (bonds and mortgage loans on real estate) is allocated to insurance lines based on the funds generated by each line at the average yield available from these fixed income assets at the time such funds become available. Net investment income from policy loans is allocated to the insurance lines according to the amount of loans made by each line. Net investment income from all other assets is allocated to the insurance lines as necessary to support the equity assigned to that line with the remainder allocated to capital & surplus.
	-2	Identifiable expenses are charged directly to the appropriate line of business. The remaining expenses are allocated to the lines based upon various factors including premium ratio within the respective lines.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies and Practices (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Accounting	'
Basis of Accounting	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.
Consolidation Policy	'
Consolidation Policy	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.
Reclassification Policy	'
Reclassification Policy	Certain amounts in prior years have been reclassified to conform to current year presentation.
Use of Estimates	'
Use of Estimates	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.
Investment Securities	'
Investment Securities	Investment securities – Bonds classified as held-to-maturity are carried at amortized cost. Bonds classified as available-for-sale are carried at fair value. Equity securities are classified as available-for-sale and carried at fair value. After-tax net unrealized gains or losses on available-for-sale securities are reflected in stockholders’ equity as a component of “Accumulated Other Comprehensive Income (Loss)” (“AOCI”).
Mortgage Loans on Real Estate	'
	Mortgage loans on real estate are stated at unpaid principal balance, adjusted for any unamortized discount, deferred expenses, and allowances. Accretion of discounts is recorded using the effective yield method. Interest income, prepayment fees and accretion of discounts and origination fees are reported in “Net investment income” in the consolidated statements of operations. Interest income earned on impaired and non-impaired loans is accrued on the principal amount of the loan based on contractual interest rate. However, interest ceases to accrue for loans on which interest is more than 90 days past due, when the collection of interest is not probable or when a loan is in foreclosure. Income on past due loans is reported on a cash basis. When a loan becomes current, it is placed back into accrual status. Cash receipts on impaired loans are recorded as a reduction of principal, interest income, expense reimbursement or other manner in accordance with the loan agreement. Gains and losses from the sale of loans and changes in allowances are reported in “Realized investment gains (losses)” in the consolidated statements of operations.
	Each mortgage loan is evaluated quarterly and placed in a watchlist if events occur or circumstances exist that could indicate that American National will be unable to collect all amounts due according to the contractual terms. Additionally, loans with estimated collateral value less than their balance and loans with characteristics indicative of higher than normal credit risks are reviewed quarterly. All loans in the watchlist are analyzed individually for impairment. If a loan is concluded to be fully collectible, no loss allowance is recorded. Loans are considered impaired when, based upon current information and events, it is probable that all amounts due under the contractual terms of the loan will be uncollectible. A specific allowance for loan losses is established for the excess carrying value of the loan over either: (i) the present value of expected future cash flows discounted at the loan’s original effective interest rate, or (ii) the estimated fair value of the underlying collateral if the loan is in the process of foreclosure or otherwise collateral dependent. Allowances are also established on groups of loans with similar characteristics, such as property types, if based on experience, it is probable that a loss has occurred and the amount of the loss can be reasonably estimated. The allowance is reviewed quarterly to determine if it is adequate, or if a recovery of the asset is assured and the allowance can be reduced.

	Management believes the recorded allowance is adequate and is the best estimate of probable loan losses, including losses incurred at the reporting date but not identified by a specific loan. Management’s quarterly evaluation of the allowance is based on historical loan loss experience, known and inherent risks in the portfolio, adverse situations affecting the borrower’s ability to repay, the estimated value of the underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. Loans are charged off as uncollectible only when the loan is forgiven by a legal agreement. Prior to charging off a loan, an allowance is recorded based on the estimated recoverable amount. Upon forgiveness, both the allowance and the loan balance are reduced which results in no further gain or loss.
Policy Loans	'
Policy Loans	Policy loans are carried at cost, which approximates fair value.
Investment Real Estate	'
Investment Real Estate	Investment real estate including related improvements, are stated at cost less accumulated depreciation. Depreciation is provided on a straight-line basis over the estimated useful life of the asset (typically 15 to 50 years). Rental income is recognized on a straight-line basis over the term of the respective lease. American National classifies a property as held-for-sale if it commits to a plan to sell a property within one year and actively markets the property in its current condition for a price that is reasonable in comparison to its estimated fair value. Real estate held-for-sale is stated at the lower of depreciated cost or estimated fair value less expected disposition costs, and is not depreciated while it is classified as held-for-sale. American National periodically reviews its investment real estate for impairment and tests properties for recoverability whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable and the carrying value of the property exceeds its estimated fair value. Properties whose carrying values are greater than their undiscounted cash flows are written down to their estimated fair value, with the impairment loss included in “Realized investment gains (losses)” in the consolidated statements of operations. Impairment losses are based upon the estimated fair value of real estate, which is generally computed using the present value of expected future cash flows from the real estate discounted at a rate commensurate with the underlying risks as well as other appraisal methods. Real estate acquired upon foreclosure is recorded at the lower of its cost, or its estimated fair value at the date of foreclosure.
Real Estate Joint Ventures and Other Limited Partnership Interests	'

	Real Estate Joint Ventures and Other Limited Partnership Interests—American National uses the equity method of accounting for its investments in real estate joint ventures and other limited partnership interests in which it has more than a minor interest or influence over the investee’s operations, but it does not have a controlling interest and is not the primary beneficiary. These investments are reported as “Investments in unconsolidated affiliates” in the consolidated statements of financial position. For certain joint ventures, American National records its share of earnings using a lag methodology of one to three months for all instances where timely financial information is not available and the contractual right does not exist to receive such financial information. In addition to the investees’ regular impairment analysis of its underlying investments, American National routinely evaluates its investments in those investees for impairments. American National considers financial and other information provided by the investee, other known information and inherent risks in the underlying investments, as well as future capital commitments, in determining whether impairment has occurred. When an impairment is deemed to have occurred at the joint venture level, American National recognizes its share within “Equity in earnings (losses) of unconsolidated affiliates” to record the investment at its fair value. When an impairment results from American National’s separate analysis, an adjustment is made through “Realized investment gains (losses)” to record the investment at its fair value.
Short-Term Investments	'

	Short-term investments comprised of commercial paper, are carried at amortized cost, which approximates fair value.
Other Invested Assets	'
Other Invested Assets	Other invested assets comprised primarily of tax credit partnerships, CAPCO investments and mineral rights, are carried at cost, less allowance for depletion, where applicable. Other invested assets also include equity-indexed options which are carried at fair value. Impairments for other invested assets are considered on an individual basis.
Impairments	'
	Impairments—American National evaluates all fixed maturity securities with unrealized losses on a quarterly basis to determine if the creditworthiness of any of those securities has deteriorated to a point where its carrying value will not be realized at maturity. For fixed maturity securities where management believes that the carrying value will not be realized, an other-than-temporary impairment (“OTTI”) loss is recorded. At December 31, 2013, the unrealized losses on fixed maturity securities that were not other-than-temporarily impaired were the result of credit spread widening. There were no delinquent coupon payments attributed to these securities at December 31, 2013.

	For all fixed maturity securities in unrealized loss positions which American National does not intend to sell and for which it is not more-likely-than-not that it will be required to sell before its anticipated recovery, American National assesses whether the amortized cost basis of securities will be recovered by comparing the net present value of the expected cash flows from those securities with its amortized cost basis. Management estimates the expected cash flows using historical experience information as well as market observable data, such as industry analyst reports and forecasts, sector credit ratings and other data relevant to the collectibility of a security. The net present value of the expected cash flows from fixed maturity securities is calculated by discounting management’s best estimate of expected cash flows from those securities at the effective interest rate implicit in the fixed maturity security when acquired. If the net present value of the expected cash flows is less than the amortized cost of the fixed maturity securities, an OTTI has occurred in the form of a credit loss. The credit loss is recognized in earnings in the amount of excess amortized cost over the net present value of the expected cash flows from the fixed maturity securities. If the fair value of the fixed maturity securities is less than the net present value of its expected cash flows at the impairment measurement date, a non-credit loss exists which is recorded in other comprehensive income (loss) for the difference between the fair value and the net present value of the expected cash flows.
	After the recognition of an OTTI, fixed maturity securities are accounted for as if they had been purchased on the OTTI measurement date, with a cost basis equal to their previous amortized cost less the related OTTI losses recognized in earnings. The new cost basis of an other-than-temporarily impaired security is not adjusted for subsequent increases in estimated fair value. Should there be a significant increase in the estimate of cash flows expected to be collected from previously impaired fixed maturity securities, the increase would be accounted for prospectively by accreting it as interest income over its remaining life.
	American National evaluates all equity securities in unrealized loss positions on a quarterly basis and recognizes an OTTI loss on those where a market price recovery is not expected in a reasonable period of time. All equity securities with unrealized losses are also evaluated for credit quality. OTTI is recognized if management believes the carrying value of securities will not be realized, regardless of the length of time that they have had an unrealized loss.
Derivative Instruments	'

	Derivative instruments are purchased as hedges of a recognized asset or liability, and are recorded on the consolidated statements of financial position at fair value. The change in fair value of derivative assets and liabilities is reported in the consolidated statements of operations as “Net investment income” and “Interest credited to policyholder account balances,” respectively. American National does not apply hedge accounting treatment to its derivative instruments. Derivative instruments held at December 31, 2013 and 2012 were immaterial to the consolidated financial statements.
Cash and Cash Equivalents	'
	Cash and cash equivalents
	Cash and cash equivalents include cash on-hand and in banks plus amounts invested in money market funds and are reported as “Cash and cash equivalents” in the consolidated statements of financial position.
Property and Equipment	'
	Property and equipment
	These assets consist of buildings occupied by American National, data processing equipment, and furniture and equipment, which are carried at cost, less accumulated depreciation. Depreciation is calculated using straight-line and accelerated methods over the estimated useful lives of the assets (3 to 50 years).
Deferred Policy Acquisition Costs	'
	Deferred policy acquisition costs (“DAC”) are the capitalized costs related directly to the successful acquisition of new or renewal insurance contracts. Significant costs are incurred to acquire insurance and annuity contracts, including commissions and certain underwriting, policy issuance and processing expenses.
	DAC on traditional life and health products is amortized with interest over the anticipated premium-paying period of the related policies, in proportion to the ratio of annual premium revenue expected to be received over the life of the policies. Expected premium revenue is estimated by using the same mortality, morbidity and withdrawal assumptions used in computing liabilities for future policy benefits. DAC is reduced by a provision for possible inflation of maintenance and settlement expenses determined by means of grading interest rates.
	DAC on universal life, limited-pay and investment-type contracts is amortized as a level percentage of the present value of anticipated gross profits from investment yields, mortality, and surrender charges. The effect of the realization of unrealized gains (losses) on DAC is recognized within AOCI in the consolidated statements of financial position as of the reporting date. A change in interest rates could have a significant impact on DAC calculated for these contracts.
	DAC associated with property and casualty business is amortized over the coverage period of the related policies, in relation to premium revenue.
	For short-duration and long-duration contracts, DAC is grouped consistent with the manner in which insurance contracts are acquired, serviced and measured for profitability and is reviewed for recoverability based on the profitability of the underlying insurance contracts. Investment income is not anticipated in assessing the recoverability of DAC for short-duration contracts.
Liabilities for Future Policy Benefits	'
Liabilities for Future Policy Benefits	Liabilities for future policy benefits for traditional products have been provided on a net level premium method based on estimated investment yields, withdrawals, mortality, and other assumptions that were appropriate at the time policies were issued. Estimates used are based on historical experience, adjusted for possible adverse deviation. These estimates are periodically reviewed and compared with actual experience. When it is determined that future expected experience differs significantly from existing assumptions the estimates are revised for current and future issues.
Policyholders' Account Balances	'
Policyholders' Account Balances	Policyholders’ account balances represent the contract value that has accrued to the benefit of the policyholders related to universal-life, limited-pay and investments-type contracts. These are generally equal to the accumulated deposits, plus interest credited, reduced by withdrawals, payouts, and accumulated policyholder assessments.
Reserves for Claims and Claim Adjustment Expenses	'
Reserves for Claims and Claim Adjustment Expenses	Reserves for claims and claim adjustment expenses (“CAE”) are established to provide for the estimated costs of paying claims. These reserves include estimates for both case reserves and incurred but not reported (“IBNR”) claim reserves. Case reserves include the liability for reported but unpaid claims. IBNR reserves include a provision for potential development on case reserves, losses on claims currently closed which may reopen in the future, as well as incurred but not reported claims. These reserves also include an estimate of the expense associated with settling claims, including legal and other fees and the general expenses of administering the claims adjustment process.
Reinsurance	'

	Reinsurance—Reinsurance recoverables are estimated amounts due to American National from reinsurers related to paid and unpaid ceded claims and CAE and are presented net of a reserve for non-recoverability. Recoveries on our gross ultimate losses are generally determined by a review of individual large claims as well as by estimating the ceded portion of IBNR using assumed distribution of loss by percentage retained. The most significant assumption used is the average size of the individual losses for those claims that have occurred but have not yet been recorded. The ultimate amount of the reinsurance ceded recoverable is unknown until all losses are settled.
Premiums, Benefits, Claims Incurred and Expenses	'
	Premiums, benefits, claims incurred and expenses
	Traditional ordinary life and health—Life and accident and health premiums are recognized as revenue when due. Benefits and expenses are associated with earned premiums to result in recognition of profits over the term of the insurance contracts.
	Annuities—Premiums received on limited-pay and supplemental annuity contracts involving a significant life contingency are recognized as revenue when due. Deferred annuity premiums are recorded as deposits rather than recognized as revenue. Revenues from deferred annuity contracts are principally surrender charges and, in the case of variable annuities, administrative fees assessed to contractholders.
	Universal life and single premium whole life revenues represent amounts assessed to policyholders. Included in revenue are mortality charges, surrender charges actually paid and earned policy service fees. Amounts included in expenses are benefits in excess of account balances returned to policyholders.
	Property and casualty premiums are recognized as revenue proportionately over the contract period, net of reinsurance ceded. Claims incurred consist of actual claims and CAE paid and the change in reserves, net of reinsurance received and recoverable.
Participating Insurance Policies	'
	Participating insurance policies
	Participating business comprised approximately 8.1% of the life insurance in-force at December 31, 2013 and 11.7% of life premiums in 2013. Of the total participating business, 78.1% was written by Farm Family Life Insurance Company (“Farm Family Life”). For the participating business excluding Farm Family Life, the allocation of dividends to participating policyowners is based upon a comparison of experienced rates of mortality, interest and expenses, as determined periodically for representative plans of insurance, issue ages and policy durations, with the corresponding rates assumed in the calculation of premiums.
	For the Farm Family Life participating business, profits earned on participating business are reserved for the payment of dividends to policyholders, except for the stockholders’ share of profits on participating policies, which is limited to the greater of 10% of the profit on participating business, or 50 cents per thousand dollars of the face amount of participating life insurance in-force. Participating policyholders’ interest includes the accumulated net income from participating policies reserved for payment to such policyholders in the form of dividends (less net income allocated to stockholders as indicated above) as well as a pro rata portion of unrealized investment gains (losses), net of tax.
Federal Income Taxes	'
	Federal income taxes
	American National Insurance Company and its eligible subsidiaries file a consolidated life and non-life federal income tax return. Certain subsidiaries that are consolidated for financial reporting are not eligible to be included in the consolidated federal income tax return; accordingly, they file separate returns.
	Deferred federal income tax assets and liabilities have been recognized to reflect the future tax consequences attributable to differences between the financial statement amounts of assets and liabilities and their respective tax bases. Deferred taxes are measured using enacted tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled.
	American National recognizes tax benefits on uncertain tax positions if it is “more-likely-than-not” the position based on its technical merits will be sustained by taxing authorities. American National recognizes the largest benefit that is greater than 50% likely of being ultimately realized upon settlement. Tax benefits not meeting the “more-likely-than-not” threshold, if applicable, are included with “Other liabilities” in the consolidated statements of financial position.
	Interest and penalties assessed, if applicable, are classified as “Other operating expenses” in the consolidated statements of operations.
Pension and Postretirement Benefit Plans	'
	Pension and postretirement benefit plans
	The pension and postretirement benefit obligations and costs are calculated using concepts in accordance with GAAP. The discount rate and the expected return on plan assets are important elements of expense and/or liability measurement, and these key assumptions are evaluated annually. Other assumptions involve demographic factors such as retirement age, mortality, turnover and compensation.
	American National uses a discount rate to determine the present value of future benefits on the measurement date. The guideline for setting this rate is a high-quality long-term corporate bond rate. To determine the expected long-term rate of return on plan assets, a building-block method is used. The expected rate of return on each asset is broken down into three components: inflation, the real risk-free rate of return (i.e., the long-term estimate of future returns on default-free U.S. government securities), and the risk premium for each asset class (i.e., the expected return in excess of the risk-free rate). Using this approach, the calculated return will fluctuate from year to year; however, it is American National’s policy to hold this long-term assumption relatively constant.
Stock-Based Compensation	'
	Stock-based compensation
	Stock Appreciation Rights—The measurement of the stock appreciation rights (“SARs”) liability and compensation cost is based on the fair value of the grants and are remeasured each reporting period through the settlement date. The fair value of the SAR’s is calculated using the Black-Scholes-Merton option-pricing model. The key assumptions used in the model include: the grant date and remeasurement date stock prices, expected life of the SARs and the risk-free rate of return. The compensation liability related to the SAR award is included in “Other liabilities” in the consolidated statements of financial position.
	Restricted Stock—The measurement of the equity and compensation cost of restricted stock (“RS”) is based on the fair value of the underlying stock at grant date. The compensation cost accrued is included in “Additional paid-in capital” in the consolidated statements of financial position.
	Restricted Stock Units—Effective December 31, 2012, American National’s Board Compensation Committee modified the settlement provision within the outstanding restricted stock units (“RSU”) providing the recipients of the awards option to settle vested RSUs in either cash or American National common stock. The modification in the settlement provision changed the RSU classification from an equity to a liability award. After the modification, the liability has been remeasured each reporting period through the vesting date and will be adjusted for the changes in fair value. The compensation liability related to the RSUs is included in “Other Liabilities” in the consolidated statement of financial position.
Separate Account Assets and Liabilities	'
	Separate account assets and liabilities
	Separate account assets and liabilities are funds intended to meet the investment objectives of contract holders who bear the investment risk. Investment income and investment gains and losses from these separate funds accrue to the benefit of the contract holders. Separate accounts are established in conformity with insurance laws and are not chargeable with liabilities that arise from any other business of American National. American National reports separately, as assets and liabilities, investments held in separate accounts and liabilities of the separate accounts if (i) such separate accounts are legally recognized; (ii) assets supporting the contract liabilities are legally insulated from American National’s general account liabilities; (iii) investments are directed by the contract holder; and (iv) all investment performance, net of contract fees and assessments, is passed through to the contract holder. The assets of these accounts are carried at fair value. Deposits, net investment income and realized investment gains and losses for these accounts are excluded from revenues, and related liability increases are excluded from benefits and expenses in the consolidated financial statements.
Litigation Contingencies	'
	Litigation contingencies
	American National reviews existing litigation matters and potential litigation items with counsel quarterly to determine if any adjustments to liabilities for possible losses are necessary. Reserves for losses are established whenever they are probable and estimable based on the best estimate of the probable loss. If no one estimate within the range of possible losses is more probable than any other, a reserve is recorded based on the lowest amount of the range.
