we also have outstanding commitments to fund additional contributions to investment partnerships in which we have an existing investment totaling $ 42.5 a0million at december 31 , 2011 .c r i t i c a l a c c o u n t i n g p o l i c i e s the preparation of financial statements often requires the selection of specific accounting methods and policies from among several acceptable alternatives .further , significant estimates and judgments may be required in selecting and applying those methods and policies in the recognition of the assets and liabilities in our balance sheet , the revenues and expenses in our statement of income , and the information that is contained in our significant accounting policies and notes to consolidated financial statements .making these estimates and judgments requires the analysis of information concerning events that may not yet be complete and of facts and circumstances that may change over time .accordingly , actual amounts or future results can differ materially from those estimates that we include currently in our consolidated financial statements , significant accounting policies , and notes .we present those significant accounting policies used in the preparation of our consolidated financial statements as an integral part of those statements within this 2011 annual report .in the following discussion , we highlight and explain further certain of those policies that are most critical to the preparation and understanding of our financial statements .other than temporary impairments of available-for-sale securities .we generally classify our investment holdings in sponsored mutual funds and the debt securities held for investment by our savings bank subsidiary as available-for-sale .at the end of each quarter , we mark the carrying amount of each investment holding to fair value and recognize an unrealized gain or loss as a component of comprehensive income within the statement of stockholders 2019 equity .we next review each individual security position that has an unrealized loss or impairment to determine if that impairment is other than temporary .in determining whether a mutual fund holding is other than temporarily impaired , we consider many factors , including the duration of time it has existed , the severity of the impairment , any subsequent changes in value , and our intent and ability to hold the security for a period of time sufficient for an anticipated recovery in fair value .subject to the other considerations noted above , with respect to duration of time , we believe a mutual fund holding with an unrealized loss that has persisted daily throughout the six months between quarter-ends is generally presumed to have an other than temporary impairment .we may also recognize an other than temporary loss of less than six months in our statement of income if the particular circumstances of the underlying investment do not warrant our belief that a near-term recovery is possible .an impaired debt security held by our savings bank subsidiary is considered to have an other than temporary loss that we will recognize in our statement of income if the impairment is caused by a change in credit quality that affects our ability to recover our amortized cost or if we intend to sell the security or believe that it is more likely than not that we will be required to sell the security before recovering cost .minor impairments of 5% ( 5 % ) or less are generally considered temporary .other than temporary impairments of equity method investments .we evaluate our equity method investments , including our investment in uti , for impairment when events or changes in circumstances indicate that the carrying value of the investment exceeds its fair value , and the decline in fair value is other than temporary .goodwill .we internally conduct , manage and report our operations as one investment advisory business .we do not have distinct operating segments or components that separately constitute a business .accordingly , we attribute goodwill to a single reportable business segment and reporting unit 2014our investment advisory business .we evaluate the carrying amount of goodwill in our balance sheet for possible impairment on an annual basis in the third quarter of each year using a fair value approach .goodwill would be considered impaired whenever our historical carrying amount exceeds the fair value of our investment advisory business .our annual testing has demonstrated that the fair value of our investment advisory business ( our market capitalization ) exceeds our carrying amount ( our stockholders 2019 equity ) and , therefore , no impairment exists .should we reach a different conclusion in the future , additional work would be performed to ascertain the amount of the non-cash impairment charge to be recognized .we must also perform impairment testing at other times if an event or circumstance occurs indicating that it is more likely than not that an impairment has been incurred .the maximum future impairment of goodwill that we could incur is the amount recognized in our balance sheet , $ 665.7 a0million .stock options .we recognize stock option-based compensation expense in our consolidated statement of income using a fair value based method .fair value methods use a valuation model for shorter-term , market-traded financial instruments to theoretically value stock option grants even though they are not available for trading and are of longer duration .the black- scholes option-pricing model that we use includes the input of certain variables that are dependent on future expectations , including the expected lives of our options from grant date to exercise date , the volatility of our underlying common shares in the market over that time period , and the rate of dividends that we will pay during that time .our estimates of these variables are made for the purpose of using the valuation model to determine an expense for each reporting period and are not subsequently adjusted .unlike most of our expenses , the resulting charge to earnings using a fair value based method is a non-cash charge that is never measured by , or adjusted based on , a cash outflow .provision for income taxes .after compensation and related costs , our provision for income taxes on our earnings is our largest annual expense .we operate in numerous states and countries through our various subsidiaries , and must allocate our income , expenses , and earnings under the various laws and regulations of each of these taxing jurisdictions .accordingly , our provision for income taxes represents our total estimate of the liability that we have incurred in doing business each year in all of our locations .annually , we file tax returns that represent our filing positions with each jurisdiction and settle our return liabilities .each jurisdiction has the right to audit those returns and may take different positions with respect to income and expense allocations and taxable earnings determinations .from time to time , we may also provide for estimated liabilities associated with uncertain tax return filing positions that are subject to , or in the process of , being audited by various tax authorities .because the determination of our annual provision is subject to judgments and estimates , it is likely that actual results will vary from those recognized in our financial statements .as a result , we recognize additions to , or reductions of , income tax expense during a reporting period that pertain to prior period provisions as our estimated liabilities are revised and actual tax returns and tax audits are settled .we recognize any such prior period adjustment in the discrete quarterly period in which it is determined .n e w ly i s s u e d b u t n o t y e t a d o p t e d a c c o u n t i n g g u i d a n c e in may 2011 , the fasb issued amended guidance clarifying how to measure and disclose fair value .we do not believe the adoption of such amended guidance on january 1 , 2012 , will have a significant effect on our consolidated financial statements .we have also considered all other newly issued accounting guidance that is applicable to our operations and the preparation of our consolidated statements , including that which we have not yet adopted .we do not believe that any such guidance will have a material effect on our financial position or results of operation. .
