NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS

American National Insurance Company and its consolidated subsidiaries (collectively “American National”) offer a broad spectrum of insurance products, including individual and group life insurance, health insurance, annuities, and property and casualty insurance. Through non-insurance subsidiaries, American National invests primarily in stocks and real estate. Business is conducted in 50 states, the District of Columbia, Puerto Rico, Guam and American Samoa. The majority of revenues are generated by the insurance business. Various distribution systems are utilized, including multiple-line exclusive agents, independent agents, third-party marketing organizations, career agents, and direct sales to the public.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and are reported in U.S. currency. American National consolidates all entities that are wholly-owned and those in which American National owns less than 100% but controls, as well as any variable interest entities in which American National is the primary beneficiary. All material intercompany 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 the current year presentation.

The interim consolidated financial statements and notes herein are unaudited and reflect all adjustments which management considers necessary for the fair presentation of the interim consolidated statements of financial position, operations, comprehensive income (loss), changes in stockholders’ equity, and cash flows.

The interim consolidated financial statements and notes should be read in conjunction with the annual consolidated financial statements and notes thereto included in American National’s Annual Report on Form 10-K as of and for the year ended December 31, 2012. The consolidated results of operations for the interim periods should not be considered indicative of results to be expected for the full year.

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.

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.

7

Amended guidance on presentation of accumulated other comprehensive income (“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 will become effective for American National on January 1, 2014 and unless stated otherwise, is not expected to 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 the 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, except for obligations addressed within existing GAAP guidance.

Actual maturities differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Residential and commercial mortgage-backed securities, which are not due at a single maturity, have been allocated to their respective categories based on the year of final contractual maturity.

As of September 30, 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

A small portion of the mortgage loan portfolio for which American National has granted concessions related to the borrowers’ ability to pay the loans is 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:

	Nine months ended September 30, 2013						Nine months ended September 30, 2012
	Number of contracts		Recorded investment pre- modification		Recorded investment post modification		Number of contracts		Recorded investment pre- modification		Recorded investment post modification

Total		1	$	6,432	$	6,432		2	$	11,122	$	11,122

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 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 the liabilities of the VIE. 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 which are consolidated in American National’s financial statements are as follows (in thousands):

	September 30, 2013		December 31, 2012
Investment real estate	$	113,214	$	162,502
Short-term investments		—		969
Cash and cash equivalents		2,372		3,671
Accrued investment income		2,146		2,641
Other receivables		9,165		11,709
Other assets		5,437		6,487
Total assets of consolidated VIEs	$	132,334	$	187,979
Notes payable	$	114,126	$	163,384
Other liabilities		5,470		6,647
Total liabilities of consolidated VIEs	$	119,596	$	170,031

The total notes payable in the consolidated statements of financial position pertain to the borrowings of the consolidated VIEs. The liability of American National Insurance Company on notes payable of the consolidated VIEs is limited to the amount of its direct or indirect investment in the respective ventures, which totaled $12,856,000 and $18,063,000 at September 30, 2013 and December 31, 2012, respectively. The current portion of notes payable was $3,200,000 and $50,884,000 at September 30, 2013 and December 31, 2012, respectively. The average interest rate on the current portion of the notes payable was 4.0% during 2013. The total long-term portion of notes payable consists of three notes with the following interest rates: 4.0%, adjusted LIBOR plus 1.0% and adjusted LIBOR plus 2.5%. 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):

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.

18

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 September 30, 2013 and December 31, 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 generally performed on a weekly basis, but no less frequently than on a monthly basis.

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 number, payment type and current status.

19

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. This volatility assumption is the range of implied volatilities that American National has determined market participants would use to price equity options that match the current derivative characteristics of our in-force equity-indexed contracts. Implied volatility can vary by term and strike price. 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 September 30, 2013 and December 31, 2012, the implied volatility used to estimate embedded derivative value ranges from 14.5% to 29.4% and 15.9.% to 30.1%, 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, unpredictable timing of repayments and the fact that it cannot be separated from the policy contract and it is settled at outstanding value, American National believes that 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.

Within the net gain (loss) for derivatives included in net investment income were unrealized gains of $39,652,000 and $16,334,000 relating to assets still held at September 30, 2013 and 2012, respectively.

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.

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

11. LIABILITY FOR UNPAID CLAIMS AND CLAIM ADJUSTMENT EXPENSES

The liability for unpaid claims and claim adjustment expenses (“claims”) for accident and health, and property and casualty insurance is included in 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 claims incurred but not reported (“IBNR”). 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.

Information regarding the liability for unpaid claims is shown below (in thousands):

	Nine months  ended September 30,

Plus reinsurance recoverables		226,822			238,268
Unpaid claims balance, ending	$	1,122,053		$	1,178,710

The net and gross reserve calculations have shown favorable development for the last several years as a result of favorable loss emergence compared to what was implied by the loss development patterns used in the original estimation of losses in prior years. Estimates for ultimate incurred claims attributable to insured events of prior years decreased by approximately $50,553,000 during the first nine months of 2013 and $46,037,000 during the same period in 2012.

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 September 30, 2013 and December 31, 2012. However, if not utilized beforehand, approximately $13,179,000 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 2011 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 or 2012, relating to uncertain tax positions. Management does not believe that 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.

SAR, RS and RSU information for the periods indicated is shown below:

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 equity to 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 gain of $84,000 and incremental cost of $2,947,000 during the three and nine months ended September 30, 2013.

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 (loss) per share

Basic earnings (losses) 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):

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-related 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 September 30, 2013 and December 31, 2012, American National Insurance Company’s statutory capital and surplus was $2,513,623,000 and $2,260,268,000, respectively. Additionally, each of the insurance subsidiaries had statutory capital and surplus at September 30, 2013 and December 31, 2012 substantially above each individual subsidiary’s authorized control level RBC.

28

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 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 $56,205,000 and $54,234,000 at September 30, 2013 and December 31, 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):

	September 30,		December 31,
	2013		2012

Property and casualty insurance entities		20,205		19,734		26,136		13,085

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 statutory net gain from operations on an annual, non-cumulative basis, or 10% of statutory surplus. Under Texas insurance law, American National Insurance Company is permitted to pay total dividends of $251,362,000 during 2013, 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.

29

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 complete 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 September 30, 2013 and December 31, 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 $6,886,000 and $4,741,000 at September 30, 2013 and December 31, 2012, respectively.

15. 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 through 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, commercial and credit-related property insurance. These products are primarily sold through multiple-line and independent agents.

• Corporate and Other—consists of net investment income on the 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 equity 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.

16. COMMITMENTS AND CONTINGENCIES

Commitments

American National had aggregate commitments at September 30, 2013, to purchase, expand or improve real estate, to fund fixed interest rate mortgage loans, and to purchase other invested assets of $337,107,000 of which $203,930,000 is expected to be funded in 2013. The remaining $133,177,000 will be funded in 2014 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 September 30, 2013 and December 31, 2012, the outstanding letters of credit were $31,595,000 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 September 30, 2013, was approximately $206,376,000, while the total cash values of the related life insurance policies was approximately $208,702,000.

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

31

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.

17. RELATED PARTY TRANSACTIONS

American National has entered into recurring transactions and agreements with certain related parties. These include mortgage loans, management contracts, agency commission contracts, marketing agreements, accident and health insurance contracts and legal services. The impact on the consolidated financial statements of the significant related party transactions is shown below (in thousands):

This loan was originated in 1999, has a current interest rate of 7.30%, and has a final maturity date of April 1, 2019. This loan is current as to principal and interest payments.

Transactions with Greer, Herz & Adams, L.L.P.: Irwin M. Herz, Jr. is an American National advisory director and a Partner with Greer, Herz Adams, L.L.P., which serves as American National’s General Counsel.

18. SUBSEQUENT EVENTS

On October 31, 2013, American National adopted certain amendments to freeze its defined benefit pension plans. Effective December 31, 2013, benefits accrued through this plan 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. Management does not anticipate any curtailment gain or loss as a result of the adoption of the plan amendments. Management anticipates a reduction in the projected future liability for these plans, but an estimate has not been determined at this time. Effective January 1, 2014, American National will shift its retirement benefits for eligible employees to contributory defined contribution plans.

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

Set forth on the following pages is management’s discussion and analysis (“MD&A”) of financial condition and results of operations for the three and nine months ended September 30, 2013 and 2012 of American National Insurance Company and its subsidiaries (referred to in this document as “we”, “our”, “us”, or the “Company”). This information should be read in conjunction with our consolidated financial statements included in Item 1, Financial Statements (unaudited), of this Form 10-Q.

Forward-Looking Statements

This document contains forward-looking statements that reflect our estimates and assumptions related to business, economic, competitive and legislative developments. Forward-looking statements generally are indicated by words such as “expects,” “intends,” “anticipates,” “plans,” “believes,” “estimates,” “will” or words of similar meaning and include, without limitation, statements regarding the outlook of our business and expected financial performance. Forward-looking statements are not a guarantee of future performance and involve various risks and uncertainties. Moreover, forward-looking statements speak only as of the date made, and we undertake no obligation to update them. Certain important factors could cause our actual results to differ, possibly materially, from our expectations or estimates. These factors are described in greater detail in Item IA, Risk Factors, in our 2012 Annual Report on Form 10-K filed with the SEC on March 8, 2013, and they include among others:

• Economic Risk Factors

• difficult conditions in the economy, which may not improve in the near future, and risks related to persistently low or unpredictable interest rates;

General Trends

On July 25, 2013, American National’s Board of Directors authorized certain retirement benefit changes that will take effect December 31, 2013. The Company will shift its retirement benefits from defined benefit pension plans to contributory defined contribution plans. As of December 31, 2013, participation and benefit accruals under the Company’s affected defined benefit pension plans will be frozen, with no additional years of service credit or salary increase credit being earned. Benefits earned by eligible employees prior to such date will not be affected. On October 31, 2013, the Board of Directors approved amendments to certain existing plans and adopted new plans to effect these retirement benefit changes.

Critical Accounting Estimates

The unaudited interim consolidated financial statements have been prepared in conformity with GAAP. In addition to GAAP, insurance companies apply specific SEC regulations when preparing the consolidated financial statements. The preparation of the consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and notes. Actual results could differ from results reported using those estimates and assumptions.

Our accounting policies inherently require the use of judgments relating to a variety of assumptions and estimates, particularly expectations of current and future mortality, morbidity, persistency, expenses, interest rates, and property and casualty loss frequency, severity, claim reporting and settlement patterns. Due to the inherent uncertainty when using the assumptions and estimates, the effect of certain accounting policies under different conditions or assumptions could vary from those reported in the consolidated financial statements.

For a discussion of our critical accounting estimates, see the MD&A in our 2012 Annual Report on Form 10-K filed with the SEC on March 8, 2013. There were no material changes in accounting policies since December 31, 2012.

(1) A negative amount of net change indicates more expense was deferred than amortized and represents a decrease to expenses in the periods indicated.

Consolidated earnings increased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to an increase in realized gains coupled with a decrease in claims in our property and casualty segment. The increase in earnings was partially offset by an increase in other operating expenses in our life and annuity segments and a decrease in premiums in our property and casualty segment.

(1) A negative amount of net change indicates more expense was deferred than amortized and represents a decrease to expenses in the periods indicated.

Earnings decreased during the quarter and year-to-date ended September 30, 2013 primarily due to an increase in operating expenses, partially offset by increases in premiums and other policy revenues.

Premiums and other revenues

Revenues from traditional life insurance products include scheduled premium payments from policyholders on whole life and term life products. The change in these premiums is impacted primarily by policy persistency and new sales during the period. Premiums increased during 2013 compared to 2012 primarily resulting from increased sales of term products following the introduction of a new portfolio of term products during 2012.

Other policy revenues include mortality charges, earned policy service fees and surrender charges on interest-sensitive life insurance policies. These charges increased during 2013 compared to 2012 primarily due to the growing block of interest-sensitive life policies.

Life insurance sales

The following table presents life insurance sales as measured by annualized premium (in thousands):

	Three months  ended September 30,							Nine months  ended September 30,
	2013		2012		Change			2013		2012		Change
Whole life	$	5,643	$	5,942	$	(299	)	$	19,044	$	17,714	$	1,330
Term life		7,756		5,628		2,128			24,436		14,916		9,520
Universal life		8,920		6,094		2,826			26,759		19,010		7,749
Total recurring	$	22,319	$	17,664	$	4,655		$	70,239	$	51,640	$	18,599
Single and excess (1)	$	584	$	393	$	191		$	1,676	$	1,540	$	136
Credit life (1)		1,107		1,063		44			3,108		2,994		114

⁽¹⁾ These are weighted amounts representing 10% of single and excess premiums and 15% of credit life premuims.

Life insurance sales based on annualized premium are non-GAAP measures used by the insurance industry, which allow a comparison of new policies written by an insurance company during the period. These consist of recurring premiums, which represent the total yearly premium that insurance companies would expect to receive if all policies would remain in force, 10% of single and excess premiums and 15% of credit life premium. Life insurance sales measure productivity associated with gaining new insurance business in the current period whereas premium revenues, a GAAP measure, are driven by policies sold in current and prior periods; therefore, a reconciliation of premium revenues and insurance sales is not meaningful.

Life insurance sales increased for the quarter and year-to-date ended September 30, 2013 due to a continued focus on life production and expansion of product offerings beginning in June 2012. Term life sales increased as a result of a new term portfolio introduced in 2012. Equity-indexed universal life products were the primary driver of the increase in universal life sales.

Benefits, losses and expenses

Policyholder benefits increased during the year-to-date ended September 30, 2013 primarily due to a block of limited pay contracts, which were evaluated as requiring additional reserves.

Commissions increased during 2013 compared to 2012 primarily due to increased sales of our term and equity-indexed universal life products.

Other operating expenses increased during the quarter and year-to-date ended September 30, 2013 compared to 2012 as a result of increases in allocated share-based compensation costs under the stock and incentive plan, costs associated with the growth in our life insurance in-force during 2013 and sales bonuses paid to independent contractors. Substantially all independent contractor bonuses are capitalized as DAC, therefore, they have minimal impact on earnings.

37

The following table presents the components of the change in DAC in the Life segment (in thousands):

	Three months  ended September 30,									Nine months  ended September 30,
	2013			2012			Change			2013			2012			Change
Acquisition cost capitalized	$	30,999		$	21,847		$	9,152		$	80,226		$	62,162		$	18,064
Amortization of DAC		(24,289	)		(19,934	)		(4,355	)		(59,201	)		(56,276	)		(2,925	)
Change in DAC (1)	$	6,710		$	1,913		$	4,797		$	21,025		$	5,886		$	15,139

(1) A positive amount of net change indicates more expense was deferred than amortized and represents a decrease to expenses in the periods indicated.

Acquisition costs capitalized increased during 2013 compared to 2012 primarily due to an increase in commissions from higher production.

Policy in-force information

The following tables summarize the changes in the Life segment’s in-force amounts (in thousands) and number of policies in-force:

	September 30,		December 31,
	2013		2012		Change
Life insurance in-force
Traditional life	$	53,518,457	$	48,856,459	$	4,661,998
Interest-sensitive life		24,882,352		24,132,101		750,251
Total life insurance in-force	$	78,400,809	$	72,988,560	$	5,412,249
Number of policies in-force
Traditional life		2,013,799		2,122,666		(108,867	)
Interest-sensitive life		193,880		185,729		8,151
Total number of policies in-force		2,207,679		2,308,395		(100,716	)

There was an increase in total life insurance in-force amounts during 2013, while there was a decrease in the total number of policies. The increase in life insurance in-force amounts is believed to be attributed to the attractiveness of our new portfolio of products and ease of doing business. The decrease in our policy count during 2013 is attributable to claims, surrenders and lapses, as well as new business activity generally being comprised of fewer but larger face-value policies.

Total benefits and expenses		157,016		163,830		(6,814	)		494,747		490,841		3,906
Income (loss) before other items and federal income taxes	$	18,631	$	25,384	$	(6,753	)	$	69,633	$	72,998	$	(3,365	)

(1) A negative amount of net change indicates more expense was deferred than amortized and represents a decrease to expenses in the periods indicated.

Earnings decreased during the quarter and year-to-date ended September 30, 2013 primarily due to an increase in other operating expenses. Another factor contributing to the decrease in quarter-to-date earnings was an increase in reserves due to a lower level of immediate annuity mortality experience. Immediate annuity mortality experience tends to stabilize when measured over a longer period, resulting in a more consistent year-to-date fluctuation in benefits in relation to premiums.

Premiums and other revenues

Annuity premium and deposit amounts received are shown below (in thousands):

	Three months  ended September 30,							Nine months  ended September 30,
	2013		2012		Change			2013		2012		Change
Fixed deferred annuity	$	50,510	$	153,318	$	(102,808	)	$	178,662	$	486,835	$	(308,173	)

We monitor account values and changes in those values to effectively manage our Annuity segment. Changes in account values are mainly the result of net inflows, surrenders, policy fees, interest credited and market value changes. Shown below are the changes in account values (in thousands):

	Nine months  ended September 30,
	2013			2012
Fixed deferred and equity-indexed annuity
Account value, beginning of period	$	9,803,197		$	9,824,416
Net inflows		183,832			374,025
Surrenders		(842,436	)		(579,908	)
Fees		(6,795	)		(6,075	)
Interest credited		262,472			275,072
Account value, end of period	$	9,400,270		$	9,887,530
Single premium immediate annuity
Reserve, beginning of period	$	1,075,638		$	978,722
Net inflows		36,436			47,751
Interest and mortality		32,726			31,523
Reserve, end of period	$	1,144,800		$	1,057,996
Variable deferred annuity
Account value, beginning of period	$	417,645		$	380,129
Net inflows		91,664			72,925
Surrenders		(84,866	)		(78,651	)
Fees		(3,945	)		(3,509	)
Change in market value and other		52,440			40,711
Account value, end of period	$	472,938		$	411,605

Fixed deferred annuity net inflows decreased during 2013 compared to 2012 primarily resulting from our management of these products to lower sales to mitigate risks associated with investing in the persistently low interest rate environment. In addition, surrenders increased during 2013 compared to 2012 primarily due to a larger block of policies reaching the end of their surrender charge period.

An equity-indexed annuity allows a policyholder to participate in equity returns while also having certain downside protection from the guaranteed minimum returns defined in the product. Deposits for this product increased during 2013 compared to 2012 primarily attributed to the current attractiveness of this product compared to fixed annuities.

Single premium immediate annuity (“SPIA”) year-to-date premiums remained relatively unchanged. However, net inflows during the year decreased when compared to prior year due primarily to a higher level of SPIA payments resulting from a growing block of SPIA in-force.

Net investment income decreased during the quarter ended September 30, 2013 compared to 2012 due to a decrease in account value of fixed deferred annuities. Net investment income increased during the year-to-date ended September 30, 2013 compared to 2012 due to an increase in option return substantially offsetting the decrease in fixed investment income resulting from the decrease in fixed defined annuity account values.

40

Benefits, losses and expenses

Policyholder benefits consist of annuity payments and reserve increases for SPIA contracts, and are highly correlated to premium volume. Benefits decreased during the quarter and year-to-date ended September 30, 2013 compared to 2012, consistent with SPIA premiums. However, the quarter-to-date decrease in benefits was lower due to an increase in reserve as a result of lower immediate annuity mortality experience. Immediate annuity mortality experience tends to stabilize when measured over longer periods resulting in a more consistent year-to-date change in benefits in relation to premiums.

Commissions decreased for 2013 compared to 2012 primarily due to reduced fixed deferred annuity production.

Other operating expenses increased during the quarter ended September 30, 2013 compared to 2012 primarily due to increases in allocated share-based compensation costs. In addition, the year-to-date increase in other operating expenses includes the effect of the reduction in the prior year expenses relating to final resolution of certain litigation being recorded as interest credited rather than operating expense.

The change in DAC represents acquisition costs capitalized less the amortization of existing DAC, which is calculated in proportion to gross profits. The following shows the components of the change in DAC (in thousands):

	Three months  ended September 30,									Nine months  ended September 30,
	2013			2012			Change			2013			2012			Change
Acquisition cost capitalized	$	12,571		$	17,398		$	(4,827	)	$	38,467		$	54,015		$	(15,548	)
Amortization of DAC		(22,974	)		(20,909	)		(2,065	)		(66,129	)		(64,333	)		(1,796	)
Change in DAC (1)	$	(10,403	)	$	(3,511	)	$	(6,892	)	$	(27,662	)	$	(10,318	)	$	(17,344	)

(1) A positive amount of net change indicates more expense was deferred than amortized and represents a decrease to expenses in the periods indicated.

Acquisition costs capitalized was lower during 2013 compared to 2012 primarily due to a decrease in commissions as a result of lower sales of new deferred annuity contracts.

An important measure of the Annuity segment is amortization of DAC as a percentage of gross profits. The amortization of DAC as a percentage of gross profits for the year-to-date ended September 30, 2013 and 2012 was 37.3% and 39.5%, respectively. The decrease in the ratio during 2013 was primarily driven by increased interest spreads.

Options and Derivatives

Shown below is the analysis of the impact to net investment income of the option return, along with the impact to interest credited of the equity-indexed annuity embedded derivative (in thousands):

	Three months  ended September 30,							Nine months  ended September 30,
	2013		2012		Change			2013		2012		Change
Net investment income
Without option return	$	135,304	$	145,634	$	(10,330	)	$	416,132	$	438,832	$	(22,700	)
Option return		13,018		10,448		2,570			47,398		21,947		25,451
Interest credited to policy account balances
Without embedded derivative		74,261		85,332		(11,071	)		229,681		263,163		(33,482	)
Equity-indexed annuity embedded derivative		10,947		7,711		3,236			39,306		16,779		22,527

Net investment income without option return decreased during the quarter and year-to-date ended September 30, 2013 primarily due to a decrease in account values of fixed deferred annuities. Interest credited to policyholders’ account balances without embedded derivative decreased during 2013 due to a decrease in crediting rates and certain non-recurring expenses relating to settled litigation, which was charged to interest credited during 2012. Without this charge, the decrease would have been $27.5 million for the year-to-date ended September 30, 2013 compared to 2012.

The option return, as well as the related equity-indexed annuity embedded derivative, increased during 2013 compared to 2012 primarily as a result of a larger number of options held during 2013, in addition to the change in the S&P 500 Index during the respective periods. Option returns correlate to the 4.7% and 17.9% return of the S&P 500 Index during the quarter and year-to-date ended September 30, 2013, respectively, compared to 5.8% and 14.6% for the same periods in 2012. The impact of the option return and equity-indexed annuity embedded derivative was a $2.1 million and $8.1 million net increase in annuity earnings during the three and nine months ended September 30, 2013, respectively.

Earnings increased during the quarter and year-to-date ended September 30, 2013 compared to the same periods in 2012 driven primarily by a decrease in claims incurred, partially offset by a decrease in premiums.

Premiums and other revenues

Health earned premiums for the periods indicated are as follows (in thousands, except percentages):

Earned premiums decreased during the quarter and year-to-date ended September 30, 2013 compared to the same periods in 2012 primarily resulting from the run-off of our closed block of medical expense insurance plans, which will continue decreasing. Medicare Supplement and credit accident and health lines also had decreases in premium. These decreases were partially offset by the increase in Managing General Underwriter (“MGU”) line.

Other income increased during the quarter and year-to-date ended September 30, 2013 due to increased activities in the MGU line.

Total in-force policies increased during the year-to-date ended September 30, 2013. Increases in the MGU line were partially offset by decreases in the remaining lines of business. The MGU line increased due to increased production by existing MGUs, and the addition of new MGUs.

Benefits, losses and expenses

Claims incurred decreased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily as the result of the continued decline in the closed medical expense block and a decrease in group claim submissions.

Other operating expenses increased during the year-to-date ended September 30, 2013 compared to 2012 due primarily to an accrual on the MGU line for an anticipated payment to a state insurance guaranty pool during the first quarter of 2013.

Change in Deferred Policy Acquisition Costs

The following table presents the components of the change in DAC (in thousands):

	Three months  ended September 30,									Nine months  ended September 30,
	2013			2012			Change			2013			2012			Change
Acquisition cost capitalized	$	4,017		$	2,840		$	1,177		$	9,457		$	8,311		$	1,146

(1) A positive amount of net change indicates more expense was deferred than amortized and represents a decrease to expenses in the periods indicated.

The amortization of DAC had a smaller impact during the year-to-date ended September 30, 2013 compared to the same period in 2012 due to the declining aggregate health block of business.

Results improved during the year-to-date ended September 30, 2013 compared to 2012 primarily as a result of a significant decrease in claims incurred. Results for the quarter-to-date remained relatively unchanged.

Premiums and other revenues

Net premiums written increased during the quarter-to-date ended September 30, 2013 compared to 2012 primarily due to increases in our homeowner, agribusiness, other commercial and credit business. Net premiums written decreased during the year-to-date ended September 30, 2013 compared to 2012 primarily as a result of decreases in our personal auto business as well as changes in our credit-related property products. Net premiums earned decreased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to decreases in premiums from our personal auto business.

Benefits, losses and expenses

Claims incurred decreased during the quarter-to-date ended September 30, 2013 compared to 2012 as a result of a decline in non-catastrophe losses due primarily to reduced loss frequency. Claims incurred and loss ratio decreased during the year-to-date ended September 30, 2013 compared to 2012 as a result of decreases in catastrophe losses, as well as improved rate adequacy and claims frequency.

Commissions increased during the quarter-to-date ended September 30, 2013 compared to 2012 corresponding with an increase in net premiums written related to collateral protection credit products. Commissions decreased during the year-to-date ended September 30, 2013 compared to 2012 primarily due to a shift from Guaranteed Auto Protection (“GAP”) commissioned products to non-commission products, which also have lower premiums.

45

Other operating expenses increased for the quarter and year-to-date ended September 30, 2013 compared to 2012, primarily due to increases in agent recruitment and marketing expenses.

Expenses attributable to the change in DAC during the quarter-to-date ended September 30, 2013 decreased compared to 2012, primarily due to higher capitalized commissions relating to the overall increase in net written premiums for commercials products. Expenses attributable to the change in DAC during the year-to-date ended September 30, 2013 increased compared to 2012, primarily due to capitalized costs on credit-related property products written in prior years being amortized while newer credit-related property products sold with lower revenue and without commissions resulted in lower cost being capitalized in the current period.

For the quarter and year-to-date ended September 30, 2013, the net favorable prior year loss and claims adjustment expenses (“CAE”) development was $19.2 million and $36.6, compared to $4.6 million and $30.8 million favorable development for the quarter and year-to-date ended September 30, 2012. This favorable development is primarily in our personal auto and commercial casualty lines, which are demonstrating favorable loss emergence compared to what was implied by our historical development patterns, as well as more favorable runoff in our commercial automobile and workers compensation lines than what was seen in the third quarter of 2012.

Products

Our Property and Casualty segment consists of: (i) Personal, which we market primarily to individuals, represents 60.7% of net premiums written, (ii) Commercial, which focuses primarily on agricultural and other commercial markets, represents 31.3% of net premiums written, and (iii) Credit-related property insurance products, which are marketed to and through financial institutions and retailers, represent 8.0% of net premiums written.

Personal Automobile: Net premiums written and earned decreased in our personal automobile line during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to a decline in policies in-force. The loss ratio decreased during the quarter-to-date ended September 30, 2013 compared to 2012 due to a decline in claim frequency.

46

Homeowners: Net premiums written and earned increased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to increasing premium rates over the time period. The loss and combined ratios increased during the quarter-to-date ended September 30, 2013 compared to 2012 due to increased catastrophe losses. The loss and combined ratios decreased during the year-to-date ended September 30, 2013 compared to 2012 primarily due to a decline in non-catastrophe weather-related losses and improved rate adequacy as well as a decline in catastrophe losses.

Other Personal: These products include watercraft, rental-owner and umbrella coverages for individuals seeking to protect their personal property and liability not covered within their homeowner and auto policies. Net premiums written and earned remained substantially unchanged during 2013 compared to 2012. The loss and combined ratios increased during the quarter-to-date ended September 30, 2013 compared to 2012, while the year-to-date ratios remained relatively unchanged. As this is currently the smallest line of business in our Personal Products, minor fluctuations in results can cause greater volatility in these ratios.

Other Commercial: Net premiums written and earned increased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to an increase in workers’ compensation premiums. The loss and combined ratios decreased significantly during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to the reduction in the frequency of both workers’ compensation and commercial liability claims.

Agribusiness Product: Our agribusiness product allows policyholders to customize and cover their agriculture exposure using a package policy which includes coverage for residences and household contents, farm buildings and building contents, personal and commercial liability and personal property. Net premiums written and earned increased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily as a result of an increase in new business writings. The loss and combined ratios increased during the quarter ended September 30, 2013 compared to 2012, primarily due to an increase in claim severity. The loss and combined ratios decreased during the year-to-date ended September 30, 2013 compared to 2012, primarily due to a combination of rate and underwriting actions.

Commercial Auto: Net premiums written and earned remained relatively unchanged during the quarter and year-to-date ended September 30, 2013 compared to 2012. The loss and combined ratios increased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to increased severity of claims.

Credit-related property products are offered on automobiles, furniture and appliances in connection with the financing of those items. These policies pay an amount if the insured property is lost or damaged and the amount paid is not directly related to an event affecting the consumer’s ability to pay the debt. The primary distribution channel for credit-related property insurance is general agents who market to sellers of covered products and financial institutions.

Net premiums written increased during the quarter-to-date ended September 30, 2013 compared to 2012 due to an increase in our GAP Waiver and collateral protection business. Net premiums written decreased during the year-to-date ended September 30, 2013 compared to 2012 as premiums shifted from GAP Insurance to GAP Waiver, a lower premium debt protection product. The loss and combined ratios increased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to an increase in claims in our collateral protection business.

Earnings increased during the quarter and year-to-date ended September 30, 2013 compared to 2012 primarily due to increases in realized gains, driven by sales of investment real estate properties as well as a reduction in other-than-temporary impairments related to investment securities.

Investments

We manage our investment portfolio to optimize the rate of return commensurate with sound and prudent asset selection and to maintain a well-diversified portfolio. Our investment operations are regulated by the state insurance departments where we or our insurance subsidiaries are domiciled. Investment activities, including the setting of investment policies and defining an acceptable risk appetite, are subject to review and approval by our Board of Directors, which is assisted by our Finance Committee and Management Risk Committee.

48

Our insurance and annuity products are primarily supported by investment-grade bonds, and to a lesser extent collateralized mortgage obligations and commercial mortgage loans. We purchase fixed maturity securities and designate them as either held-to-maturity or available-for-sale considering our estimated future cash flow needs. We also monitor the composition of our fixed maturity securities and adjust the mix within the portfolio as investments mature or new investments are purchased.

We invest in commercial mortgage loans when the yield and credit risk compare favorably with fixed maturity securities. Individual residential mortgage loans have not been part of our investment portfolio, and we do not anticipate investing in them in the future. We invest in real estate and equity securities based on a risk and reward analysis where we believe there are opportunities for enhanced returns.

Composition of Invested Assets

The following summarizes the carrying values of our invested assets (other than investments in unconsolidated affiliates) by asset class (in thousands, except percentages):

	September 30, 2013					December 31, 2012
	Amount		Percent			Amount		Percent
Bonds held-to-maturity, at amortized cost	$	8,674,301		45.1	%	$	9,009,282		46.8	%
Bonds available-for-sale, at fair value		4,557,161		23.7			4,665,576		24.3
Equity securities, at fair value		1,277,131		6.6			1,075,439		5.6
Mortgage loans on real estate, net of allowance		3,333,363		17.4			3,143,011		16.2
Policy loans		395,709		2.1			395,333		2.1
Investment real estate, net of accumulated depreciation		471,810		2.5			511,233		2.7
Short-term investments		339,479		1.8			313,086		1.6
Other invested assets		161,515		0.8			125,104		0.7
Total investments	$	19,210,469		100.0	%	$	19,238,064		100.0	%

The decrease in our total investments as of September 30, 2013 as compared to December 31, 2012 was primarily a result of decreases in bonds and investment real estate, which were partially offset by increases in equity securities and mortgage loans. The decrease in bonds was primarily due to sales and maturities of bonds coupled with fair value decreases in corporate debt securities, while the decrease in investment real estate was due to disposition of certain real estate properties. The increase in equity securities is primarily attributed to a 17.9% increase in the S&P 500 year-to-date.

Each component of our invested assets and its related revenues are described further in the Notes to the Unaudited Consolidated Financial Statements. Additionally, Note 2, Summary of Significant Accounting Policies and Practices, of the Notes to the Consolidated Financial Statements within our Annual Report on Form 10-K for the year ended December 31, 2012 filed with the SEC on March 8, 2013 contains a detailed description of the Company’s methodology for evaluating other-than-temporary impairment losses on its investments.

Bonds—We allocate most of our fixed maturity securities to support our insurance business. At September 30, 2013, our fixed maturity securities had an estimated fair market value of $13.7 billion, which was $0.6 billion, or 4.7%, above amortized cost. At December 31, 2012, our fixed maturity securities had an estimated fair value of $14.5 billion, which was $1.2 billion, or 8.9%, above amortized cost.

The estimated fair value of fixed maturity securities, due in one year or less, decreased to $1.2 billion as of September 30, 2013 from $1.7 billion as of December 31, 2012, primarily as a result of long-term bonds maturing during the period.

49

The following table identifies the total bonds by credit quality rating, using both Standard & Poor’s and Moody’s ratings (in thousands, except percentages):

	September 30, 2013						December 31, 2012
	Amortized		Estimated		% of Fair		Amortized		Estimated		% of Fair
	Cost		Fair Value		Value		Cost		Fair Value		Value

We expect the exposure to below investment grade securities to decrease as these bonds approach maturity. We do not own direct investments in sovereign debt issued by Greece, Ireland, Italy, Portugal or Spain.

Equity Securities—Our equity portfolio consists of companies publicly traded on U.S. national stock exchanges; the cost and estimated value of the equity securities are as follows (in thousands):

	September 30, 2013
			Unrealized		Unrealized					% of Fair
	Cost		Gains		Losses			Fair Value		Value
Common stock	$	701,968	$	543,559	$	(6,232	)	$	1,239,295		97.0
Preferred stock		22,690		15,440		(294	)		37,836		3.0
Total	$	724,658	$	558,999	$	(6,526	)	$	1,277,131		100.0
	December 31, 2012
			Unrealized		Unrealized					% of Fair
	Cost		Gains		Losses			Fair Value		Value
Common stock	$	660,889	$	383,634	$	(6,739	)	$	1,037,784		96.5
Preferred stock		27,690		9,995		(30	)		37,655		3.5
Total	$	688,579	$	393,629	$	(6,769	)	$	1,075,439		100.0

Mortgage Loans—We invest in commercial mortgage loans that are diversified by property-type and geography to support our insurance business. Generally, mortgage loans are secured by first liens on income-producing real estate with a loan-to-value ratio of up to 75%. Mortgage loans held-for-investment are carried at outstanding principal balances, adjusted for any unamortized premium or discount, deferred fees or expenses, and net of allowances. The weighted average coupon yields on the principal funded for mortgage loans were 5.0% and 5.5% at September 30, 2013 and December 31, 2012, respectively. It is likely that the weighted average coupon yield on funded mortgage loans will decline as loans mature and new loans are originated with lower rates in the current interest rate environment.

Policy Loans—For certain life insurance products, policyholders may borrow funds using the policy’s cash value as collateral. The maximum amount of the policy loan depends upon the policy’s surrender value and the number of years since policy origination. As of September 30, 2013, we had $395.7 million in policy loans with a loan to surrender value of 59.2%, and at December 31, 2012, we had $395.3 million in policy loans with a loan to surrender value of 59.5%. Interest rates on policy loans primarily range from 3.0% to 12.0% per annum. Policy loans may be repaid at any time by the policyholder and have priority to any claims on the policy. If the policyholder fails to repay the policy loan, funds are withdrawn from the policy’s benefits.

Investment Real Estate—We invest in commercial real estate with positive cash flows or where appreciation in value is expected. Real estate may be owned directly by our insurance companies, non-insurance affiliates or joint ventures. The carrying value of real estate is stated at cost, less accumulated depreciation and valuation allowances, if any. Depreciation is provided over the estimated useful lives of the properties.

50

Short-Term Investments—Short-term investments are primarily commercial paper rated at least A2/P2 by Standard & Poor’s and Moody’s, respectively. The amount fluctuates depending on the available long-term investment opportunities and our liquidity needs, including mortgage investment-funding commitments.

Net Investment Income and Realized Gains (Losses)

Net investment income during the quarter and year-to-date ended September 30, 2013 decreased $3.9 million and $2.0 million, respectively, compared to the same periods during 2012. The decrease was due primarily to bonds with lower interest yields making up a larger percentage of our portfolio as older bonds, which were purchased when interest rates were higher, matured. The decrease in bonds was partially offset by the $2.8 million and $26.1 million increases in option income during the quarter and year-to-date, respectively, resulting from increases in the underlying equity markets index.

Interest income on mortgage loans is accrued on the principal amount of the loan based on the contractual interest rate. Accretion of discounts is recorded using the effective yield method. Interest income, accretion of discounts and prepayment fees are reported in net investment income. Interest is not accrued on loans generally more than 90 days past due or when the collection of interest is not considered probable. Loans in foreclosure are placed on non-accrual status. Interest received on non-accrual status mortgage loans is included in net investment income in the period received.

Realized gains for the quarter and year-to-date ended September 30, 2013 increased $16.9 million and $60.6 million, respectively, as compared to the same periods in 2012, primarily as a result of realized gains on sales of investment real estate and equity securities. Other-than-temporary impairments decreased $13.7 million and $18.6 million for the quarter and year-to-date ended September 30, 2013, respectively, due to a decrease in bond impairments. In the third quarter of 2012, we recorded $12.7 million of other-than-temporary impairments on bonds.

Net Unrealized Gains and Losses

The net unrealized gains on available-for-sale securities at September 30, 2013 and December 31, 2012 were $738.1 and $736.0 million, respectively; a net increase of $2.1 million for the year-to-date ended September 30, 2013. Unrealized gains or losses on available-for-sale securities have no impact on earnings. Rather, they are recognized as other comprehensive income or loss, which directly impacts equity. The gross unrealized gains of available-for-sale securities increased $41.8 million to $799.1 million for the year-to-date ended September 30, 2013 primarily resulting from fair value increases in equity securities. The gross unrealized losses of available-for-sale securities increased to $61.0 million from $21.4 million. The $39.6 million increase in gross unrealized losses during the year-to-date ended September 30, 2013, was primarily attributable to corporate debt securities.

The gross unrealized gains on held-to-maturity securities decreased $319.5 million to $520.0 million during the year-to-date ended September 30, 2013 primarily attributable to fair value decreases in certain corporate debt securities. The gross unrealized losses on held-to-maturity securities increased $84.1 million to $92.1 million during 2013 primarily attributable to certain corporate debt securities.

The fair value of our investment securities is affected by fixed maturity securities approaching maturity and for all investments by various factors, including volatility of financial markets, changes in interest rates and fluctuations in credit spread. We have the ability and intent to hold those securities in unrealized loss positions until a market price recovery or maturity. Further, it is unlikely that we will be required to sell them prior to recovery, and recovery is expected within a reasonable period of time.

51

Liquidity

Our liquidity requirements have been and are expected to continue to be met by funds from operations, comprised of premiums received from our customers and investment income. The primary use of cash has been and is expected to continue to be the payment of policyholder benefits and claims incurred. Current and expected patterns of claim frequency and severity may change from period to period but continue to be within historical norms. Management considers our current liquidity position to be sufficient to meet anticipated demands over the next twelve months. Our contractual obligations are not expected to have a significant negative impact to cash flow from operations.

Current continued low-interest rate environments are expected to curtail our appetite to sell the volume of annuity contracts we sold in previous years and to require us to consider higher than historical contributions to our defined benefit plans covering our employees. There are no other known trends or uncertainties regarding product pricing, changes in product lines or rising costs, that would have a significant impact to cash flows from operations. Additionally, we have paid dividends to stockholders for over 100 consecutive years and expect to continue this trend. No unusually large capital expenditures are expected in the next 12-24 months.

The funds received as premium payments and deposits are invested primarily in bonds and commercial mortgages. Funds are invested with the intent that income from the investments and proceeds from the maturities will meet our ongoing cash flow needs. Historically we have not had to liquidate invested assets in order to cover cash flow needs. Additionally, our portfolio of highly liquid available-for-sale investment securities is available to meet future liquidity needs as necessary.

Our cash, cash equivalents and short-term investment position was $462.1 million and $616.1 million at September 30, 2013 and December 31, 2012, respectively. The $154.0 million decrease relates primarily to increased opportunity in long-term investments during the quarter.

A downgrade or a potential downgrade in our financial strength ratings could result in a loss of business and could adversely affect our cash flow from operations. Further information regarding additional sources or uses of cash is described in Note 16, Commitments and Contingencies, of the Notes to the Unaudited Consolidated Financial Statements.

Capital Resources

Our capital resources are summarized below (in thousands):

	September 30,		December 31,
	2013		2012
American National stockholders’ equity, excluding accumulated other comprehensive income (loss), net of tax (“AOCI”)	$	3,729,421	$	3,585,826
AOCI		281,995		242,010
Total American National stockholders’ equity	$	4,011,416	$	3,827,836

We have notes payable that are not part of our capital resources relating to amounts borrowed by real estate joint ventures that we consolidate into our financial statements. The lenders for the notes payable have no recourse against us in the event of default by the joint ventures. Therefore, the only amount of liability we have for these notes payable is limited to our investment in the respective ventures, which totaled $12.9 million and $18.1 million at September 30, 2013 and December 31, 2012, respectively.

Statutory Capital and Surplus and Risk-based Capital

Statutory capital and surplus is the capital of our insurance companies reported in accordance with accounting practices prescribed or permitted by the applicable state insurance departments. Risk-based capital (“RBC”) is a standard calculation using formulas and instructions from the National Association of Insurance Commissioners. State laws specify regulatory actions if an insurer’s ratio of statutory capital and surplus to RBC falls below certain levels. The RBC formula for life insurance companies establishes capital requirements for asset, interest rate, market, insurance and business risks. The RBC formula for property and casualty insurance companies establishes capital requirements for asset and underwriting risks including reserve risk.

The achievement of long-term growth will require growth in American National Insurance Company’s statutory capital and surplus. Our subsidiaries may obtain additional statutory capital through various sources, such as retained statutory earnings or equity contributions from us. For additional details see Statutory Capital and Surplus leading in Note 14, Stockholders’ Equity and Noncontrolling Interests, of the Notes to the Unaudited Consolidated Financial Statements.

Contractual Obligations

Our future cash payments associated with claims and claims adjustment expenses, life, annuity and disability obligations, contractual obligations pursuant to operating leases for office space and equipment, and notes payable have not materially changed since December 31, 2012. We expect to have the capacity to pay our obligations as they come due.

Off-Balance Sheet Arrangements

We have off-balance sheet arrangements relating to third-party marketing operation bank loans discussed in Note 16, Commitments and Contingencies, of the Notes to the Unaudited Consolidated Financial Statements. We could be exposed to a liability for these loans, which are supported by the cash value of the underlying insurance contracts. The cash value of the life insurance policies is designed to always equal or exceed the balance of the loans. Accordingly, management does not foresee any loss related to these arrangements.

Related-Party Transactions

We have various agency, consulting and service arrangements with individuals and entities considered to be related parties. Each of these arrangements has been reviewed and approved by our Audit Committee, which retains final decision-making authority for these transactions. The total amount involved in these arrangements, both individually and in the aggregate, is not material to any segment or to our overall operations. For additional details see Note 17, Related Party Transactions, of the Notes to the Unaudited Consolidated Financial Statements in Item 1.

Our market risks have not changed materially from those disclosed in our 2012 Annual Report on Form 10-K filed with the SEC on March 8, 2013.

ITEM 4. CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)) that are designed to ensure that information required to be disclosed in the Company’s reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Corporate Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The Company’s management, with the participation of the Company’s Chief Executive Officer and Corporate Chief Financial Officer, has evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of September 30, 2013. Based upon that evaluation and subject to the foregoing, the Company’s Chief Executive Officer and Corporate Chief Financial Officer concluded that, as of September 30, 2013, the design and operation of the Company’s disclosure controls and procedures were effective to accomplish their objectives at the reasonable assurance level.

Management has monitored the internal controls over financial reporting, including any material changes to the internal control over financial reporting. There were no changes in the Company’s internal control over financial reporting (as that term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the year-to-date ended September 30, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Accounting Changes And Error Corrections [Abstract]

Recently Issued Accounting Pronouncements

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 accumulated other comprehensive income (“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 will become effective for American National on January 1, 2014 and unless stated otherwise, is not expected to 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 the 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, except for obligations addressed within existing GAAP guidance.

Liability for Unpaid Claims and Claim Adjustment Expenses

11. LIABILITY FOR UNPAID CLAIMS AND CLAIM ADJUSTMENT EXPENSES

The liability for unpaid claims and claim adjustment expenses (“claims”) for accident and health, and property and casualty insurance is included in 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 claims incurred but not reported (“IBNR”). 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.

Information regarding the liability for unpaid claims is shown below (in thousands):

	Nine months  ended September 30,
	2013			2012
Unpaid claims balance, beginning	$	1,168,047		$	1,180,259
Less reinsurance recoverables		256,885			235,174
Net beginning balance		911,162			945,085
Incurred related to
Current		743,194			779,602
Prior years		(50,553	)		(46,037	)
Total incurred claims		692,641			733,565
Paid claims related to
Current		442,100			454,183
Prior years		266,472			284,025
Total paid claims		708,572			738,208
Net balance		895,231			940,442
Plus reinsurance recoverables		226,822			238,268
Unpaid claims balance, ending	$	1,122,053		$	1,178,710

The net and gross reserve calculations have shown favorable development for the last several years as a result of favorable loss emergence compared to what was implied by the loss development patterns used in the original estimation of losses in prior years. Estimates for ultimate incurred claims attributable to insured events of prior years decreased by approximately $50,553,000 during the first nine months of 2013 and $46,037,000 during the same period in 2012.

Summary of Significant Accounting Policies and Practices (Policies)

9 Months Ended

Sep. 30, 2013

Accounting Policies [Abstract]

Basis of Accounting

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and are reported in U.S. currency.

The interim consolidated financial statements and notes herein are unaudited and reflect all adjustments which management considers necessary for the fair presentation of the interim consolidated statements of financial position, operations, comprehensive income (loss), changes in stockholders’ equity, and cash flows.

The interim consolidated financial statements and notes should be read in conjunction with the annual consolidated financial statements and notes thereto included in American National’s Annual Report on Form 10-K as of and for the year ended December 31, 2012. The consolidated results of operations for the interim periods should not be considered indicative of results to be expected for the full year.

Consolidation Policy

American National consolidates all entities that are wholly-owned and those in which American National owns less than 100% but controls, as well as any variable interest entities in which American National is the primary beneficiary. All material intercompany transactions with consolidated entities have been eliminated. Investments in unconsolidated affiliates are accounted for using the equity method of accounting.

Reclassification Policy

Certain amounts in prior years have been reclassified to conform to the current year presentation.

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.

18. SUBSEQUENT EVENTS

On October 31, 2013, American National adopted certain amendments to freeze its defined benefit pension plans. Effective December 31, 2013, benefits accrued through this plan 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. Management does not anticipate any curtailment gain or loss as a result of the adoption of the plan amendments. Management anticipates a reduction in the projected future liability for these plans, but an estimate has not been determined at this time. Effective January 1, 2014, American National will shift its retirement benefits for eligible employees to contributory defined contribution plans.

Actual maturities differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Residential and commercial mortgage-backed securities, which are not due at a single maturity, have been allocated to their respective categories based on the year of final contractual maturity.

All gains and losses for securities sold throughout the year were determined using specific identification of the securities sold. During the nine months ended September 30, 2013 and 2012, bonds with a carrying value of $13,492,000 and $34,227,000, 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 $263,000 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.

As of September 30, 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.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies and Practices

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and are reported in U.S. currency. American National consolidates all entities that are wholly-owned and those in which American National owns less than 100% but controls, as well as any variable interest entities in which American National is the primary beneficiary. All material intercompany 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 the current year presentation.

The interim consolidated financial statements and notes herein are unaudited and reflect all adjustments which management considers necessary for the fair presentation of the interim consolidated statements of financial position, operations, comprehensive income (loss), changes in stockholders’ equity, and cash flows.

The interim consolidated financial statements and notes should be read in conjunction with the annual consolidated financial statements and notes thereto included in American National’s Annual Report on Form 10-K as of and for the year ended December 31, 2012. The consolidated results of operations for the interim periods should not be considered indicative of results to be expected for the full year.

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.

Commitments and Contingencies

16. COMMITMENTS AND CONTINGENCIES

Commitments

American National had aggregate commitments at September 30, 2013, to purchase, expand or improve real estate, to fund fixed interest rate mortgage loans, and to purchase other invested assets of $337,107,000 of which $203,930,000 is expected to be funded in 2013. The remaining $133,177,000 will be funded in 2014 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 September 30, 2013 and December 31, 2012, the outstanding letters of credit were $31,595,000 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 September 30, 2013, was approximately $206,376,000, while the total cash values of the related life insurance policies was approximately $208,702,000.

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.

American National and its wholly-owned subsidiaries regularly invest in real estate partnerships and joint ventures. American National 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 the liabilities of the VIE. 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 which are consolidated in American National’s financial statements are as follows (in thousands):

	September 30, 2013		December 31, 2012
Investment real estate	$	113,214	$	162,502

Other liabilities		5,470		6,647
Total liabilities of consolidated VIEs	$	119,596	$	170,031

The total notes payable in the consolidated statements of financial position pertain to the borrowings of the consolidated VIEs. The liability of American National Insurance Company on notes payable of the consolidated VIEs is limited to the amount of its direct or indirect investment in the respective ventures, which totaled $12,856,000 and $18,063,000 at September 30, 2013 and December 31, 2012, respectively. The current portion of notes payable was $3,200,000 and $50,884,000 at September 30, 2013 and December 31, 2012, respectively. The average interest rate on the current portion of the notes payable was 4.0% during 2013. The total long-term portion of notes payable consists of three notes with the following interest rates: 4.0%, adjusted LIBOR plus 1.0% and adjusted LIBOR plus 2.5%. 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):

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 September 30, 2013 and December 31, 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 generally performed on a weekly basis, but no less frequently than on a monthly basis.

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 number, 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. This volatility assumption is the range of implied volatilities that American National has determined market participants would use to price equity options that match the current derivative characteristics of our in-force equity-indexed contracts. Implied volatility can vary by term and strike price. 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 September 30, 2013 and December 31, 2012, the implied volatility used to estimate embedded derivative value ranges from 14.5% to 29.4% and 15.9.% to 30.1%, 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, unpredictable timing of repayments and the fact that it cannot be separated from the policy contract and it is settled at outstanding value, American National believes that 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.

Total mortgage loans are net of unamortized discounts of $898,000 and $4,346,000 and unamortized origination fees of $15,599,000 and $14,076,000 at September 30, 2013 and December 31, 2012, respectively. No unearned income is included in these amounts.

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.

The change in allowance for credit losses in commercial mortgage loans is shown below (in thousands):

Troubled Debt Restructurings

A small portion of the mortgage loan portfolio for which American National has granted concessions related to the borrowers’ ability to pay the loans is 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:

	Nine months ended September 30, 2013						Nine months ended September 30, 2012
	Number of contracts		Recorded investment pre- modification		Recorded investment post modification		Number of contracts		Recorded investment pre- modification		Recorded investment post modification
Office		1	$	6,432	$	6,432		1	$	6,803	$	6,803
Retail		—		—		—		1		4,319		4,319
Total		1	$	6,432	$	6,432		2	$	11,122	$	11,122

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 made payments of $37,784,000 and $20,293,000 during the nine months ended September 30, 2013 and 2012, respectively.

The tax effects of temporary differences that gave rise to the deferred tax assets and liabilities are shown below (in thousands):

	September 30,			December 31,
	2013			2012
DEFERRED TAX ASSETS
Investments, principally due to impairment losses	$	71,740		$	74,117
Investment in real estate and other invested assets principally due to investment valuation allowances		8,580			7,259
Policyholder funds, principally due to policy reserve discount		230,922			229,429
Policyholder funds, principally due to unearned premium reserve		32,916			30,337

Gross deferred tax assets		502,827			503,933
DEFERRED TAX LIABILITIES
Available-for-sale securities, principally due to net unrealized gains		257,847			257,290
Investment in bonds, principally due to accrual of discount on bonds		5,994			9,415
Deferred policy acquisition costs, due to difference between GAAP and tax amortization methods		338,928			327,245
Property, plant and equipment, principally due to difference between
GAAP and tax depreciation methods		8,113			1,462
Other liabilities		12,937			671
Gross deferred tax liabilities		623,819			596,083
Total net deferred tax assets (liabilities)	$	(120,992	)	$	(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 September 30, 2013 and December 31, 2012. However, if not utilized beforehand, approximately $13,179,000 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 2011 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 or 2012, relating to uncertain tax positions. Management does not believe that there are any uncertain tax benefits that could be recognized within the next twelve months that would decrease American National’s effective tax rate.

Segment Information

15. 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 through 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, commercial and credit-related property insurance. These products are primarily sold through multiple-line and independent agents.

• Corporate and Other—consists of net investment income on the 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 equity 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.

Stockholders' Equity and Noncontrolling Interests

	September 30,			December 31,
	2013			2012

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.

SAR, RS and RSU information for the periods indicated is shown below:

	SAR					RS Shares					RS Units

December 31, 2012		3,000			N/A			7,974,000

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 equity to 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 gain of $84,000 and incremental cost of $2,947,000 during the three and nine months ended September 30, 2013.

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 (loss) per share

Basic earnings (losses) 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):

	Three months ended September 30,				Nine months ended September 30,
	2013		2012		2013		2012
Weighted average shares outstanding		26,780,313		26,736,464		26,789,564		26,699,211

Diluted earnings (loss) per share		3.07		2.20		7.46		4.65

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-related 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 September 30, 2013 and December 31, 2012, American National Insurance Company’s statutory capital and surplus was $2,513,623,000 and $2,260,268,000, respectively. Additionally, each of the insurance subsidiaries had statutory capital and surplus at September 30, 2013 and December 31, 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 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 $56,205,000 and $54,234,000 at September 30, 2013 and December 31, 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):

	September 30,		December 31,
	2013		2012
Statutory capital and surplus
Life insurance entities	$	3,013,474	$	2,750,786

Property and casualty insurance entities		20,205		19,734		26,136		13,085

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 statutory net gain from operations on an annual, non-cumulative basis, or 10% of statutory surplus. Under Texas insurance law, American National Insurance Company is permitted to pay total dividends of $251,362,000 during 2013, 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 complete 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 September 30, 2013 and December 31, 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 $6,886,000 and $4,741,000 at September 30, 2013 and December 31, 2012, respectively.
