To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements and income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including allowance for credit losses and purchased credit-impaired (PCI) loans (Note 6), valuations of residential mortgage servicing rights (MSRs) (Notes 8 and 9) and financial instruments (Note 1</font><font style="font-family:Georgia;font-size:9pt;">7</font><font style="font-family:Georgia;font-size:9pt;">), liability for mortgage loan repurchase losses (Note 9) and income taxes (Note 2</font><font style="font-family:Georgia;font-size:9pt;">1</font><font style="font-family:Georgia;font-size:9pt;">).

These changes are effective for us in first quarter 2013 with retrospective application.

Use Of Estimates

UseOfEstimates

Our accounting and reporting policies conform with U.S. generally accepted accounting principles (GAAP) and practices in the financial services industry. To prepare the financial statements in conformity with GAAP, management must make estimates based on assumptions about future economic and market conditions (for example, unemployment, market liquidity, real estate prices, etc.) that affect the reported amounts of assets and liabilities at the date of the financial statements and income and expenses during the reporting period and the related disclosures. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Management has made significant estimates in several areas, including allowance for credit losses and purchased credit-impaired (PCI) loans (Note 6), valuations of residential mortgage servicing rights (MSRs) (Notes 8 and 9) and financial instruments (Note 17), liability for mortgage loan repurchase losses (Note 9) and income taxes (Note 21). Actual results could differ from those estimates.

Adoption Of Asu201108 Option To Perform Qualitative Assessment Of Goodwill To Test For Impairment

AdoptionOfAsu201108OptionToPerformQualitativeAssessmentOfGoodwillToTestForImpairment

ASU 2011-08 provides entities with the option to perform a qualitative assessment of goodwill to test for impairment. If, based on qualitative reviews, a company concludes that more likely than not a reporting unit's fair value is less than its carrying amount, then the company must complete quantitative steps to determine if there is goodwill impairment. If a company concludes otherwise, quantitative tests are not required. Our adoption of this Update did not affect our consolidated financial statements.

Accounting Standard Not Yet Adopted Asu201111 Expansion Of Disclosure Requirements For Financial Instruments That May Be Offset In Accordance With Enforceable Master Netting Agreements Or Similar Arrangements

AccountingStandardNotYetAdoptedAsu201111ExpansionOfDisclosureRequirementsForFinancialInstrumentsThatMayBeOffsetInAccordanceWithEnforceableMasterNettingAgreementsOrSimilarArrangements

ASU 2011-11 expands the disclosure requirements for financial instruments and derivatives that may be offset in accordance with enforceable master netting agreements or similar arrangements. The disclosures are required regardless of whether the instruments have been offset (or netted) in the statement of financial position. Under ASU 2011-11, companies must describe the nature of offsetting arrangements and provide quantitative information about those agreements, including the gross and net amounts of financial instruments that are recognized in the statement of financial position. These changes are effective for us in first quarter 2013 with retrospective application. This Update will not affect our consolidated financial results since it amends only the disclosure requirements for offsetting financial instruments.

AccountingStandardNotYetAdoptedAsu201105EliminationOfOptionForCompaniesToIncludeComponentsOfOtherComprehensiveIncomeInStatementOfChangesInStockholdersEquity

ASU 2011-05 eliminates the option for companies to include the components of other comprehensive income in the statement of changes in stockholders' equity. This Update requires entities to present the components of comprehensive income in either a single statement or in two separate statements, with the statement of other comprehensive income (OCI) immediately following the statement of income. This Update also requires companies to present amounts reclassified out of OCI and into net income on the face of the statement of income. The remaining provisions are effective for us in first quarter 2012 with retrospective application. Early adoption is permitted. This Update will not affect our consolidated financial results as it amends only the presentation of comprehensive income.

Defined Benefit Plan Assumptions Used Calculating Benefit Obligation Discount Rate Support Methodology And Source Data

DefinedBenefitPlanAssumptionsUsedCalculatingBenefitObligationDiscountRateSupportMethodologyAndSourceData

We use a consistent methodology to determine the discount rate that is based on an established yield curve methodology. This methodology incorporates a broad group of top quartile Aa bonds consisting of approximately 250-275 bonds. The discount rate is determined by matching this yield curve with the timing and amounts of the expected benefit payments for our plans.

DescriptionOfDefinedContributionPensionAndOtherPostretirementPlans

Under the 401(k) Plan, after one month of service, eligible employees may contribute up to 50% of their certified compensation, although there may be a lower limit for certain highly compensated employees in order to maintain the qualified status of the 401(k) Plan. Eligible employees who complete one year of service are eligible for company matching contributions, which are generally dollar for dollar up to 6% of an employee's certified compensation. Effective January 1, 2010, previous and future matching contributions are 100% vested for active participants.
