Donegal Mutual Insurance Company (“Donegal Mutual”) organized us as an insurance holding company on August 26, 1986 (see “Business - History and Organizational Structure” for more information). Our insurance subsidiaries, Atlantic States Insurance Company (“Atlantic States”), Southern Insurance Company of Virginia (“Southern”), Le Mars Insurance Company (“Le Mars”), The Peninsula Insurance Company and Peninsula Indemnity Company (collectively, “Peninsula Group”), Sheboygan Falls Insurance Company (“Sheboygan Falls”) and Michigan Insurance Company (“MICO”) write personal and commercial lines of property and casualty coverages exclusively through a network of independent insurance agents in certain Mid-Atlantic, Midwest, New England and Southern states. We acquired MICO on December 1, 2010 and we have included MICO’s results of operations in our consolidated results from that date. The personal lines products of our insurance subsidiaries consist primarily of homeowners and private passenger automobile policies. The commercial lines products of our insurance subsidiaries consist primarily of commercial automobile, commercial multi-peril and workers’ compensation policies. We also own 48.2% of the outstanding stock of Donegal Financial Services Corporation (“DFSC”), a unitary thrift holding company. Donegal Mutual owns the remaining 51.8% of the outstanding stock of DFSC.
At December 31, 2011, Donegal Mutual held approximately 39% of our outstanding Class A common stock and approximately 75% of our outstanding Class B common stock. As a result of this ownership, Donegal Mutual has 66% of the aggregate voting power of our outstanding shares of Class A common stock and our outstanding shares of Class B common stock. Donegal Mutual and Atlantic States entered into a proportional reinsurance agreement, or pooling agreement, effective October 1, 1986. Under this pooling agreement, Donegal Mutual and Atlantic States pool and then share proportionately substantially all of their respective premiums, losses and expenses. Atlantic States’ participation in the pool has been 80% since March 1, 2008. The operations of our insurance subsidiaries and Donegal Mutual are interrelated due to the pooling agreement and other factors. While maintaining the separate corporate existence of each company, our insurance subsidiaries and Donegal Mutual conduct business together as the Donegal Insurance Group. As such, Donegal Mutual and our insurance subsidiaries share the same business philosophy, the same management, the same employees and the same facilities and offer the same types of insurance products (see “Business - History and Organizational Structure” for more information regarding the pooling agreement and other transactions with our affiliates).
Reserve estimates can change over time because of unexpected changes in assumptions related to our insurance subsidiaries’ external environment and, to a lesser extent, assumptions as to our insurance subsidiaries’ internal operations. For example, our insurance subsidiaries have experienced a decrease in claims frequency on workers’ compensation claims during the past several years while claims severity has gradually increased. These trend changes give rise to greater uncertainty as to the pattern of future loss settlements on workers’ compensation claims. Related uncertainties regarding future trends include the cost of medical technologies and procedures and changes in the utilization of medical procedures. Assumptions related to our insurance subsidiaries’ external environment include the absence of significant changes in tort law and the legal environment that increase liability exposure, consistency in judicial interpretations of insurance coverage and policy provisions and the rate of loss cost inflation. Internal assumptions include consistency in the recording of premium and loss statistics, consistency in the recording of claims, payment and case reserving methodology, accurate measurement of the impact of rate changes and changes in policy provisions, consistency in the quality and characteristics of business written within a given line of business and consistency in reinsurance coverage and collectability of reinsured losses, among other items. To the extent our insurance subsidiaries determine that underlying factors impacting their assumptions have changed, our insurance subsidiaries attempt to make appropriate adjustments for such changes in their reserves. Accordingly, our insurance subsidiaries’ ultimate liability for unpaid losses and loss expenses will likely differ from the amount recorded at December 31, 2011. For every 1% change in our insurance subsidiaries’ estimate for loss and loss expense reserves, net of reinsurance recoverable, the effect on our pre-tax results of operations would be approximately $2.4 million.
The establishment of appropriate liabilities is an inherently uncertain process and we can provide no assurance that our insurance subsidiaries’ ultimate liability will not exceed our insurance subsidiaries’ loss and loss expense reserves and have an
adverse effect on our results of operations and financial condition. Furthermore, we cannot predict the timing, frequency and extent of adjustments to our insurance subsidiaries’ estimated future liabilities, since the historical conditions and events that serve as a basis for our insurance subsidiaries’ estimates of ultimate claim costs may change. As is the case for substantially all property and casualty insurance companies, our insurance subsidiaries have found it necessary in the past to increase their estimated future liabilities for losses and loss expenses in certain periods and, in other periods, their estimates have exceeded their actual liabilities. Changes in our insurance subsidiaries’ estimate of their liability for losses and loss expenses generally reflect actual payments and their evaluation of information received since the prior reporting date. Our insurance subsidiaries recognized a (decrease) increase in their liability for losses and loss expenses of prior years of ($168,460), ($2.9) million and $9.8 million in 2011, 2010 and 2009, respectively. Our insurance subsidiaries made no significant changes in their reserving philosophy, key reserving assumptions or claims management personnel, and there have been no significant offsetting changes in estimates that increased or decreased their loss and loss expense reserves in those years. The 2011 development represented an immaterial percentage of the December 31, 2010 net carried reserves.
Excluding the impact of weather events, our insurance subsidiaries have noted stable amounts in the number of claims incurred and a slight downward trend in the number of claims outstanding at period ends relative to their premium base in recent years across most of their lines of business. However, the amount of the average claim outstanding has increased gradually over the past several years as the property and casualty insurance industry has experienced increased litigation trends and economic conditions that have extended the estimated length of disabilities and contributed to increased medical loss costs and a general slowing of settlement rates in litigated claims. Our insurance subsidiaries could have to make further adjustments to their estimates in the future. However, on the basis of our insurance subsidiaries’ internal procedures, which analyze, among other things, their prior assumptions, their experience with similar cases and historical trends such as reserving patterns, loss payments, pending levels of unpaid claims and product mix, as well as court decisions, economic conditions and public attitudes, we believe that our insurance subsidiaries have made adequate provision for their liability for losses and loss expenses.
Atlantic States’ participation in the pool with Donegal Mutual exposes it to adverse loss development on the business of Donegal Mutual that is included in the pool. However, pooled business represents the predominant percentage of the net underwriting activity of both companies, and Donegal Mutual and Atlantic States would proportionately share any adverse risk development of the pooled business. The business in the pool is homogeneous and each company has a pro-rata share of the entire pool. Since substantially all of the business of Atlantic States and Donegal Mutual is pooled and the results shared by each company according to its participation level under the terms of the pooling agreement, the intent of the underwriting pool is to produce a more uniform and stable underwriting result from year to year for each company than they would experience individually and to spread the risk of loss between the companies.
Our insurance subsidiaries’ liability for losses and loss expenses by major line of business at December 31, 2011 and 2010 consisted of the following:
Our insurance subsidiaries seek to enhance their underwriting results by carefully selecting the product lines they underwrite. For personal lines products, our insurance subsidiaries insure standard and preferred risks in private passenger automobile and homeowners lines. For commercial lines products, the commercial risks that our insurance subsidiaries primarily insure are mercantile risks, business offices, wholesalers, service providers, contractors and artisan risks, limiting industrial and manufacturing exposures. Our insurance subsidiaries have limited exposure to asbestos and other environmental liabilities. Our insurance subsidiaries write no medical malpractice or professional liability risks. Through the consistent application of this disciplined underwriting philosophy, our insurance subsidiaries have avoided many of the “long-tail” issues other insurance companies have faced. We consider workers’ compensation to be a “long-tail” line of business, in that workers’ compensation claims tend to be settled over a longer timeframe than those in our other lines of business.
The following table presents 2011 and 2010 claim count and payment amount information for workers’ compensation. Workers’ compensation losses primarily consist of indemnity and medical costs for injured workers.
Our insurance subsidiaries’ loss ratio, which is the ratio of incurred losses and loss expenses to premiums earned, was 78.9% in 2011, compared to 72.6% in 2010. Our insurance subsidiaries’ commercial lines loss ratio increased to 71.8% in 2011, compared to 66.6% in 2010. This increase resulted primarily from the commercial automobile loss ratio increasing to 72.4% in 2011, compared to 55.5% in 2010, and the commercial multi-peril ratio increasing to 74.8% in 2011, compared to 67.4% in 2010, as a result of increased claim severity. The personal lines loss ratio increased to 82.8% in 2011, compared to 75.3% in 2010, primarily as a result of an increase in the homeowners loss ratio to 97.1% in 2011, compared to 80.7% in 2010, as a result of an increase in weather-related claims. Our insurance subsidiaries incurred total weather-related losses of $52.6 million for 2011, compared to $33.0 million for 2010 and more than twice our prior five-year average of $23.3 million. Our insurance subsidiaries had virtually no development during 2011 in their reserves for prior accident years, compared to $2.9 million in favorable development for 2010.
Our interest expense in 2011 was $2.1 million, compared to $799,578 in 2010. The higher interest expense in 2011 reflects an increase in our borrowings under our line of credit.
Our income tax benefit was $7.2 million in 2011, compared to $1.6 million in 2010. We recorded an income tax benefit based upon our loss before income tax and tax-exempt interest income earned for 2011. We carried back a portion of our 2011 net operating loss to the taxable income of prior years and our income tax benefit for 2011 reflected a current tax benefit for the carryback. We expect to apply the remainder of the 2011 net operating loss to taxable income we generate in future periods, and our income tax benefit for 2011 reflected a deferred tax benefit for the carryforward.
Our stockholders’ equity increased by $3.3 million in 2011. We attribute the increase to an increase in our net after-tax unrealized gains within our available-for-sale fixed maturity and equity investment portfolio from $8.6 million at December 31, 2010 to $23.5 million at December 31, 2011. Book value per share increased by 1.0% to $15.01 at December 31, 2011, compared to $14.86 a year earlier. Our return on average equity was 0.1% for 2011, compared to 3.0% for 2010.
Our insurance subsidiaries’ net premiums earned increased to $378.0 million for 2010, an increase of $23.0 million, or 6.5%, over 2009. Our insurance subsidiaries’ net earned premiums during 2010 have grown due to the increase in written premiums during 2009. Our insurance subsidiaries earn premiums and recognize them as income over the terms of the policies they issue. Such terms are generally one year or less in duration. Therefore, increases or decreases in net premiums earned will generally reflect increases or decreases in net premiums written in the preceding twelve-month period compared to the same period one year earlier.
For 2010, our net investment income was $19.9 million, a slight decrease from 2009. An increase in our average invested assets from $649.5 million in 2009 to $697.7 million in 2010 was offset by a decrease in our annualized average rate of return to 2.9% in 2010, compared to 3.2% in 2009. The decrease in our annualized average rate of return on investments was primarily due to lower reinvestment rates for securities added to our fixed income portfolio during 2010.
Our insurance subsidiaries’ installment fees increased primarily as a result of increases in policy counts during 2010.
Our net realized investment gains in 2010 and 2009 were $4.4 million and $4.5 million, respectively. Realized investment gains in 2010 resulted primarily from sales of equity securities as well as fixed maturity investments that had appreciated significantly during the year. We recognized no impairment charges in 2010 or 2009. The net realized investment gains in both periods resulted from turnover within our investment portfolio.
Our insurance subsidiaries’ expense ratio, which is the ratio of policy acquisition and other underwriting expenses to premiums earned, was 32.0% in 2010, compared to 31.3% in 2009.
Our interest expense in 2010 was $799,578, compared to $1.7 million in 2009. We attribute the decrease in interest expense to the interest expense we paid in 2009 related to a premium tax litigation settlement.
Our income tax (benefit) expense was ($1.6) million in 2010, compared to $1.8 million in 2009. For 2010, our tax-exempt interest income exceeded our taxable income. As a result, we carried back a net operating loss to the taxable income of prior years and our income tax benefit reflects a current tax benefit for the carryback.
Our net income in 2010 was $11.5 million, or $.46 per share of Class A common stock and $.41 per share of Class B common stock, compared to our net income of $18.8 million, or $.76 per share of Class A common stock and $.68 per share of Class B common stock, in 2009. Our Class A shares outstanding increased slightly to 20.0 million at December 31, 2010, compared to 19.9 million at December 31, 2009. Our Class B shares outstanding remained at 5.6 million.
We estimate the timing of the amounts for the net liability for unpaid losses and loss expenses of our insurance subsidiaries based on historical experience and expectations of future payment patterns. We have shown the liability net of reinsurance recoverable on unpaid losses and loss expenses to reflect expected future cash flows related to such liability. Assumed amounts from the underwriting pool with Donegal Mutual represent a substantial portion of our insurance subsidiaries’ gross liability for unpaid losses and loss expenses and ceded amounts to the underwriting pool represent a substantial portion of our insurance subsidiaries’ reinsurance recoverable on unpaid losses and loss expenses. We will include future cash settlement of Atlantic States’ assumed liability from the pool in our monthly settlements of pooled activity, wherein we net amounts ceded to and assumed from the pool. Although Donegal Mutual and Atlantic States do not anticipate any further changes in the pool participation levels in the foreseeable future, any such change would be prospective in nature and therefore would not impact the timing of expected payments for Atlantic States’ proportionate liability for pooled losses occurring in periods prior to the effective date of such change.
We, Donegal Mutual and DFSC have entered into a capital maintenance agreement with UCB, whereby we, Donegal Mutual and DFSC have agreed to make such capital contributions to UCB in the combined aggregate maximum amount that would not exceed $20.0 million as may be necessary from time to time to ensure that UCB has sufficient capital as demonstrated by UCB’s maintenance of certain capital ratios. At December 31, 2011, UCB had capital ratios substantially above the minimum requirements under the agreement.
The carrying value of our fixed maturity investments represented 89.8% and 91.8% of our total invested assets at December 31, 2011 and 2010, respectively.
Our fixed maturity investments consisted of high-quality marketable bonds, of which 99.0% were rated at investment-grade levels at December 31, 2011 and 2010. As we invested excess cash from operations and proceeds from maturities of fixed maturity investments during 2011, we decreased our holdings of tax-exempt fixed maturities to reduce the percentage of our total portfolio that is invested in municipal securities.
At December 31, 2011, the net unrealized gain on available-for-sale fixed maturity investments, net of deferred taxes, amounted to $21.3 million, compared to $1.7 million at December 31, 2010.
In September 2011, the FASB issued new guidance related to evaluating goodwill for impairment. The new guidance provides entities with the option to perform a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount before applying the quantitative two-step goodwill impairment test. If an entity concludes that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it would not be required to perform the quantitative two-step goodwill impairment test. Entities also have the option to bypass the assessment of qualitative factors for any reporting unit in any period and proceed directly to performing the first step of the quantitative two-step goodwill impairment test, as was required prior to the issuance of this new guidance. An entity may begin or resume performing the qualitative assessment in any subsequent period. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We adopted this new guidance in 2011. The adoption of this new guidance did not impact our financial position, results of operations or cash flows.
We make estimates and assumptions that can have a significant effect on amounts and disclosures we report in our consolidated financial statements. The most significant estimates relate to our insurance subsidiaries’ reserves for property and casualty insurance unpaid losses and loss expenses, valuation of investments and determination of other-than-temporary impairment and our insurance subsidiaries’ policy acquisition costs. While we believe our estimates and the estimates of our insurance subsidiaries are appropriate, the ultimate amounts may differ from the estimates provided. We regularly review our methods for making these estimates as well as the continuing appropriateness of the estimated amounts, and we reflect any adjustment we consider necessary in our current results of operations.
We make estimates concerning the valuation of our investments and the recognition of other-than-temporary declines in the value of our investments. For equity securities, we write down the investment to its fair value and we reflect the amount of the write-down as a realized loss in our results of operations when we consider the decline in value of an individual investment to be other than temporary. We individually monitor all of our investments for other-than-temporary declines in value. Generally, we assume there has been an other-than-temporary decline in value if an individual equity security has depreciated in value by more than 20% of original cost and has been in such an unrealized loss position for more than six months. Effective April 1,
2009, we adopted new accounting guidance related to the accounting for and presentation of impairment losses on debt securities. With respect to a debt security that is in an unrealized loss position, we first assess if we intend to sell the debt security. If we determine we intend to sell the debt security, we recognize the impairment loss in our results of operations. If we do not intend to sell the debt security, we determine whether it is more likely than not that we will be required to sell the security prior to recovery. If we determine it is more likely than not that we will be required to sell the debt security prior to recovery, we recognize an impairment loss in our results of operations. If we determine it is more likely than not that we will not be required to sell the debt security prior to recovery, we then evaluate whether a credit loss has occurred. We determine whether a credit loss has occurred by comparing the amortized cost of the debt security to the present value of the cash flows we expect to collect. If we expect a cash flow shortfall, we consider that a credit loss has occurred. If we determine that a credit loss has occurred, we consider the impairment to be other than temporary. We then recognize the amount of the impairment loss related to the credit loss in our results of operations, and we recognize the remaining portion of the impairment loss in our other comprehensive income, net of applicable taxes. In addition, we may write down securities in an unrealized loss position based on a number of other factors, including when the fair value of an investment is significantly below its cost, when the financial condition of the issuer of a security has deteriorated, the occurrence of industry, company or geographic events that have negatively impacted the value of a security and rating agency downgrades.
Investments - We present our investments in available-for-sale fixed maturity and equity securities at estimated fair value. The estimated fair value of a security may differ from the amount that could be realized if we sold the security in a forced transaction. In addition, the valuation of fixed maturity investments is more subjective when markets are less liquid, increasing the potential that the estimated fair value does not reflect the price at which an actual transaction would occur. We utilize nationally recognized independent pricing services to estimate fair values for our fixed maturity and equity investments. We generally obtain one price per security. The pricing services utilize market quotations for fixed maturity and equity securities that have quoted prices in active markets. For fixed maturity securities that generally do not trade on a daily basis, the pricing services prepare estimates of fair value measurements based predominantly on observable market inputs. The pricing services do not use broker quotes in determining the fair values of our investments. Our investment personnel review the estimates of fair value the pricing services provide to determine if the estimates obtained are representative of fair values based upon their general knowledge of the market, their research findings related to unusual fluctuations in value and their comparison of such values to execution prices for similar securities. Our investment personnel monitor the market and are familiar with current trading ranges for similar securities and pricing of specific investments. Our investment personnel review all pricing estimates that we receive from the pricing services against their expectations with respect to pricing based on fair market curves, security ratings, coupon rates, security type and recent trading activity. Our investment personnel review documentation with respect to the pricing services’ pricing methodology that they obtain periodically to determine if the primary pricing sources, market inputs and pricing frequency for various security types are reasonable. We refer to Note 6 - Fair Value Measurements for more information regarding our methods and assumptions in estimating fair values.
Premiums and Reinsurance Receivables and Payables - The carrying amounts reported in the balance sheet for these instruments related to premiums and paid losses and loss expenses approximate their fair values.
Our insurance subsidiaries maintain liabilities for the payment of losses and loss expenses with respect to both reported and unreported claims. Our insurance subsidiaries establish these liabilities for the purpose of covering the ultimate costs of settling all losses, including investigation and litigation costs. Our insurance subsidiaries base the amount of their liability for reported losses primarily upon a case-by-case evaluation of the type of risk involved, knowledge of the circumstances surrounding each claim and the insurance policy provisions relating to the type of loss their policyholder incurred. Our insurance subsidiaries determine the amount of their liability for unreported claims and loss expenses on the basis of historical information by line of insurance. Our insurance subsidiaries account for inflation in the reserving function through analysis of costs and trends and reviews of historical reserving results. Our insurance subsidiaries closely monitor their liabilities and recompute them periodically using new information on reported claims and a variety of statistical techniques. Our insurance subsidiaries do not discount their liabilities for losses.
the recording of claims, payment and case reserving methodology, accurate measurement of the impact of rate changes and changes in policy provisions, consistency in the quality and characteristics of business written within a given line of business and consistency in reinsurance coverage and collectibility of reinsured losses, among other items. To the extent our insurance subsidiaries determine that underlying factors impacting their assumptions have changed, our insurance subsidiaries attempt to make appropriate adjustments for such changes in their reserves. Accordingly, our insurance subsidiaries’ ultimate liability for unpaid losses and loss expenses will likely differ from the amount recorded.
Our insurance subsidiaries provide property and liability insurance coverages through independent insurance agencies located throughout their operating areas. Our insurance subsidiaries bill the majority of this business directly to the insured, although our insurance subsidiaries bill a portion of their commercial business through their agents, to whom they extend credit in the normal course of business.
We measure all share-based payments to employees, including grants of stock options, using a fair-value-based method and record such expense in our results of operations. In determining the expense we record for stock options granted to directors and employees of our subsidiaries and affiliates other than Donegal Mutual, we estimate the fair value of each option award on the date of grant using the Black-Scholes option pricing model. The significant assumptions we utilize in applying the Black-Scholes option pricing model are the risk-free interest rate, expected term, dividend yield and expected volatility.
Goodwill represents the excess of the purchase price over the underlying fair value of acquired entities. When completing acquisitions, we seek to also identify separately identifiable intangible assets that we have acquired. We assess goodwill and intangible assets with an indefinite useful life for impairment annually. We also assess goodwill and other intangible assets for impairment upon the occurrence of certain events. In making our assessment, we consider a number of factors including operating results, business plans, economic projections, anticipated future cash flows and current market data. Inherent uncertainties exist with respect to these factors and to our judgment in applying them when we make our assessment. Impairment of goodwill and other intangible assets could result from changes in economic and operating conditions in future periods.
In September 2011, the FASB issued new guidance related to evaluating goodwill for impairment. The new guidance provides entities with the option to perform a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount before applying the quantitative two-step goodwill impairment test. If an entity concludes that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it would not be required to perform the quantitative two-step goodwill impairment test. Entities also have the option to bypass the
assessment of qualitative factors for any reporting unit in any period and proceed directly to performing the first step of the quantitative two-step goodwill impairment test, as was required prior to the issuance of this new guidance. An entity may begin or resume performing the qualitative assessment in any subsequent period. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We adopted this new guidance in 2011. The adoption of this new guidance did not impact our financial position, results of operations or cash flows.
Our insurance subsidiaries conduct business and have various agreements with Donegal Mutual that we describe in the following subparagraphs:
The following amounts represent reinsurance Atlantic States assumed from the pool during 2011, 2010 and 2009:
The following amounts represent reinsurance that our insurance subsidiaries ceded to Donegal Mutual pursuant to these reinsurance agreements during 2011, 2010 and 2009:
Donegal Mutual provides facilities, management and other services to us and our insurance subsidiaries. Donegal Mutual allocates certain related expenses to Atlantic States in relation to the relative participation of Atlantic States and Donegal Mutual in the pooling agreement. Our insurance subsidiaries other than Atlantic States reimburse Donegal Mutual for their personnel costs and bear their proportionate share of information services costs based on their percentage of the total written premiums of the Donegal Insurance Group. Charges for these services totalled $64,711,860, $63,982,793 and $60,175,789 for 2011, 2010 and 2009, respectively.
We recorded goodwill of $4.7 million in connection with the MICO acquisition. The goodwill consists largely of economies of scale we expect to realize from integrating the operations of MICO with the operations of the Donegal Insurance Group and benefits we expect to derive from MICO’s relationships with its independent agents and policyholders. We have evaluated the goodwill for impairment during 2011. We will evaluate the goodwill for impairment annually or upon the occurrence of certain future events.
Our consolidated financial statements for the year ended December 31, 2010 include the operations of MICO from December 1, 2010, the date we acquired it. Effective on December 1, 2010, MICO entered into a 50% quota-share reinsurance agreement with third-party reinsurers and a 25% quota-share reinsurance agreement with Donegal Mutual to replace the 75% quota-share reinsurance agreement MICO maintained with West Bend through November 30, 2010. Donegal Mutual includes the business it assumes from MICO in its pooling agreement with Atlantic States. Our total revenues related to the operations of MICO and Atlantic States’ allocation with respect to Donegal Mutual’s quota-share reinsurance agreement for the period December 1, 2010 through December 31, 2010 were approximately $2.4 million. MICO’s results of operations for the period December 1, 2010 through December 31, 2010 did not significantly impact our consolidated net income for 2010.
The amortized cost and estimated fair values of fixed maturities and equity securities at December 31, 2011 and 2010 are as follows:
At December 31, 2011, our holdings of obligations of states and political subdivisions included general obligation bonds with an aggregate fair value of $372.2 million and an amortized cost of $348.4 million. Our holdings also included special revenue bonds with an aggregate fair value of $86.5 million and an amortized cost of $81.0 million. With respect to both categories, we held no securities of any issuer that comprised more than 10% of the category at December 31, 2011. Education bonds and water and sewer utility bonds represented 59% and 17%, respectively, of our total investments in special revenue bonds based on their carrying values at December 31, 2011. Many of the issuers of the special revenue bonds we held at December 31, 2011 have the authority to impose ad valorem taxes. In that respect, many of the special revenue bonds we held were similar to general obligation bonds.
We set forth below the amortized cost and estimated fair value of fixed maturities at December 31, 2011 by contractual maturity. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.
We present below gross realized gains and losses from investments and the change in the difference between fair value and cost of investments:
We held fixed maturities and equity securities with unrealized losses representing declines that we considered temporary at December 31, 2010 as follows:
We make estimates concerning the valuation of our investments and the recognition of other-than-temporary declines in the value of our investments. For equity securities, we write down the investment to its fair value, and we reflect the amount of the write-down as a realized loss in our results of operations when we consider the decline in value of an individual investment to be other than temporary. We individually monitor all investments for other-than-temporary declines in value. Generally, we assume there has been an other-than-temporary decline in value if an individual equity security has depreciated in value by more than 20% of original cost and has been in such an unrealized loss position for more than six months. We held 12 equity securities that were in an unrealized loss position at December 31, 2011. Based upon our analysis of general market conditions and underlying factors impacting these equity securities, we considered these declines in value to be temporary. With respect to a debt security that is in an unrealized loss position, we first assess if we intend to sell the debt security. If we determine we intend to sell the debt security, we recognize the impairment loss in our results of operations. If we do not intend to sell the debt security, we determine whether it is more likely than not that we will be required to sell the debt security prior to recovery. If we determine it is more likely than not that we will be required to sell the debt security prior to recovery, we recognize an impairment loss in our results of operations. If we determine it is more likely than not that we will not be required to sell the debt security prior to recovery, we then evaluate whether a credit loss has occurred. We determine whether a credit loss has occurred by comparing the amortized cost of the debt security to the present value of the cash flows we expect to collect. If we expect a cash flow shortfall, we consider that a credit loss has occurred. If we determine that a credit loss has occurred, we consider the impairment to be other than temporary. We then recognize the amount of the impairment loss related to the credit loss in our results of operations, and we recognize the remaining portion of the impairment loss in our other comprehensive income, net of applicable taxes. In addition, we may write down securities in an unrealized loss position based on a number of other factors, including when the fair value of an investment is significantly below its cost, when the financial condition of the issuer of a security has deteriorated, the occurrence of industry, company or geographic events that have negatively impacted the value of a security and rating agency downgrades. We held 21 debt securities that were in an unrealized loss position at December 31, 2011. Based upon our analysis of general market conditions and underlying factors impacting these debt securities, we considered these declines in value to be temporary.
For investments that have quoted market prices in active markets, we use the quoted market price as fair value and include these investments in Level 1 of the fair value hierarchy. We classify publicly traded equity securities as Level 1. When quoted market prices in active markets are not available, we base fair values on quoted market prices of comparable instruments or price estimates we obtain from independent pricing services through a bank trustee. We classify our fixed maturity investments as Level 2. Our fixed maturity investments consist of U.S. Treasury securities and obligations of U.S. government corporations and agencies, obligations of states and political subdivisions, corporate securities and residential mortgage-backed securities.
We evaluate our assets and liabilities on a regular basis to determine the appropriate level at which to classify them for each reporting period. Based on our review of the methodology and summary of inputs used by the pricing services, we have concluded that our Level 1 and Level 2 investments were classified properly at December 31, 2011 and 2010.
The following table presents our fair value measurements for our investments in available-for-sale fixed maturity and equity securities at December 31, 2010:
Our insurance subsidiaries recognized a (decrease) increase in their liability for losses and loss expenses of prior years of ($168,460), ($2.9) million and $9.8 million in 2011, 2010 and 2009, respectively. Our insurance subsidiaries made no significant changes in their reserving philosophy, key reserving assumptions or claims management personnel, and have made no significant offsetting changes in estimates that increased or decreased their loss and loss expense reserves in these years. The 2011 development represented an immaterial percentage of the December 31, 2010 net carried reserves. The 2010 development represented 1.6% of the December 31, 2009 net carried reserves and resulted primarily from lower-than-expected severity in the private passenger automobile liability and homeowners lines of business in accident years prior to 2009. The 2009
development represented 6.0% of the December 31, 2008 net carried reserves and resulted primarily from higher-than-expected severity in the private passenger automobile liability, homeowners and workers’ compensation lines of business in accident year 2008.

We provide a valuation allowance when we believe it is more likely than not that we will not realize some portion of the tax asset. At December 31, 2011 and 2010, we established a valuation allowance of $440,778 and $746,368, respectively, related to a portion of the net operating loss carryforward of Le Mars that we acquired on January 1, 2004. We have determined that we are not required to establish a valuation allowance for the other net deferred tax assets of $34.6 million and $29.1 million at December 31, 2011 and 2010, respectively, since it is more likely than not that we will realize these deferred tax assets through reversals of existing temporary differences, future taxable income, carrybacks to taxable income in prior years and the implementation of tax-planning strategies.
