| Fair Value                            | FAIR VALUEGeneral As of September 30, 2013, $12.1 billion of the Company’s total assets consisted of financial instruments measured at fair value on a recurring basis, including financial instruments for which the Company elected the fair value option. Approximately $9.9 million of these financial instruments were measured using quoted market prices for identical instruments or Level 1 inputs. Approximately $11.9 billion of these financial instruments were measured using valuation methodologies involving market-based and market-derived information, or Level 2 inputs. Approximately $194.4 million of these financial instruments were measured using model-based techniques, or Level 3 inputs, and represented approximately 1.6% of total assets measured at fair value and approximately 0.3% of total consolidated assets.Fair value is defined in U.S. GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standard focuses on the exit price in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. U.S. GAAP establishes a fair value reporting hierarchy to maximize the use of observable inputs when measuring fair value and defines the three levels of inputs as noted below:•Level 1 - Assets or liabilities for which the identical item is traded on an active exchange, such as publicly-traded instruments or futures contracts.•Level 2 - Assets and liabilities valued based on observable market data for similar instruments. Fair value is estimated using inputs other than quoted prices included within Level 1 that are observable for assets or liabilities, either directly or indirectly.NOTE 14.  FAIR VALUE (continued)•Level 3 - Assets or liabilities for which significant valuation assumptions are not readily observable in the market; and instruments valued based on the best available data, some of which is internally developed and considers risk premiums that a market participant would require. Fair value is estimated using unobservable inputs that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities may include financial instruments whose value is determined using pricing services, pricing models with internally developed assumptions, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Assets and liabilities measured at fair value, by their nature, result in a higher degree of financial statement volatility. When available, the Company attempts to use quoted market prices or matrix pricing in active markets to determine fair value and classifies such items as Level 1 or Level 2 assets or liabilities. If quoted market prices in active markets are not available, fair value is determined using third-party broker quotes and/or discounted cash flow models incorporating various assumptions including interest rates, prepayment speeds and credit losses. Assets and liabilities valued using broker quotes and/or discounted cash flow models are classified as either Level 2 or Level 3, depending on the lowest level classification of an input that is considered significant to the overall valuation. The Company values assets and liabilities based on the principal market on which each would be sold (in the case of assets) or transferred (in the case of liabilities). The principal market is the forum with the greatest volume and level of activity. In the absence of a principal market, the valuation is based on the most advantageous market. In the absence of observable market transactions, the Company considers liquidity valuation adjustments to reflect the uncertainty in pricing the instruments. The fair value of a financial asset is measured on a stand-alone basis and cannot be measured as a group, with the exception of certain financial instruments held and managed on a net portfolio basis. In measuring the fair value of a nonfinancial asset, the Company assumes the highest and best use of the asset by a market participant, not just the intended use, to maximize the value of the asset. The Company also considers whether any credit valuation adjustments are necessary based on the counterparty's credit quality.Any models used to determine fair values or validate dealer quotes based on the descriptions below are subject to review and testing as part of the Company's model validation and internal control testing processes. The Bank's Market Risk Department is responsible for determining and approving the fair values of all assets and liabilities valued at fair value, including our Level 3 assets and liabilities. Price validation procedures are performed and the results are reviewed for Level 3 assets and liabilities by the Market Risk Department. Price validation procedures performed for these assets and liabilities can include comparing current prices to historical pricing trends by collateral type and vintage, comparing prices by product type to indicative pricing grids published by market makers, and obtaining corroborating dealer prices for significant securities.The Company reviews the assumptions utilized to determine fair value on a quarterly basis. Any changes in methodologies or significant inputs used in determining fair values are further reviewed to determine if a change in fair value level hierarchy has occurred. Transfers in and out of Levels 1, 2 and 3 are considered to be effective as of the end of the quarter in which they occur.There were no transfers between Levels 1, 2 and 3 during the three and nine-month periods ended September 30, 2013 for any assets or liabilities valued at fair value on a recurring basis. During the Company's review of its investment portfolio performed during the first three months of 2012, the Company transferred its collateralized loan obligation securities ("CLOs"), which are asset-backed securities, from Level 2 to Level 3 due to the lack of price transparency in connection with its limited trading activity. The CLOs are valued using a third-party pricing service. Late in the third quarter of 2012, the Company changed its third-party pricing indications from an issuing broker to a pricing service, as the new provider is able to provide a more precise and market-driven valuation for these types of investments. During the Company's review of valuation methodologies in the fourth quarter of 2012, it was determined that the pricing techniques utilized by the provider would be considered Level 2. Therefore, during the fourth quarter of 2012, CLOs were transferred back to Level 2 from Level 3. NOTE 14.

FAIR VALUE (continued)Assets and Liabilities Measured at Fair Value on a Nonrecurring BasisThe Company may be required to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with U.S. GAAP from time to time. These adjustments to fair value usually result from application of lower-of-cost-or-fair value accounting or certain impairment measures. Assets measured at fair value on a nonrecurring basis that were still held on the balance sheet were as follows:Quoted Prices in ActiveMarkets forIdentical Assets (Level 1) Significant OtherObservable Inputs(Level 2) SignificantUnobservableInputs (Level 3) Fair Value (in thousands)September 30, 2013       Impaired loans held for investment$— $131,208 $122,612 $253,820Foreclosed assets— 54,337 — 54,337        December 31, 2012       Impaired loans held for investment$— $506,637 $40,674 $547,311Foreclosed assets— 39,904 — 39,904Valuation Processes and TechniquesImpaired loans held for investment represents the recorded investment of impaired commercial loans for which the Company periodically records nonrecurring adjustments of collateral-dependent loans measured for impairment when establishing the allowance for loan losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan. Appraisals are obtained to support the fair value of the collateral and incorporate measures such as recent sales prices for comparable properties, which are considered Level 2 inputs. Loans for which the value of the underlying collateral is determined using a combination of real estate appraisals, field exams and internal calculations are considered Level 3 inputs. The inputs in the internal calculations include the loan balance, estimation of the collectability of the underlying receivables held by the customer used as collateral, sale and liquidation value of the inventory held by the customer used as collateral, and historical loss-given-default parameters. In cases in which the carrying value exceeds the fair value of the collateral less cost to sell, an impairment charge is recognized. The total carrying value of these loans was $188.7 million and $485.6 million at September 30, 2013 and December 31, 2012, respectively. Foreclosed assets represents the recorded investment in assets taken in foreclosure of defaulted loans, and is primarily comprised of commercial and residential real property and are generally measured at the lower of cost or fair value less costs to sell. The fair value of the real property is generally determined using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace.

FAIR VALUE (continued)Valuation Processes and Techniques - Recurring Fair Value Assets and LiabilitiesFollowing is a description of the valuation techniques used for instruments measured at fair value on a recurring basis. Investment securities available for saleThe Company utilizes a third-party pricing service to value its investment portfolio. Our primary pricing service has consistently proved to be a high quality third-party pricing provider. For those investments not valued by our primary servicer, other trusted market sources are utilized. The vendors the Company uses provide pricing services on a global basis. The Company monitors and validates the reliability of vendor pricing on an ongoing basis, which can include pricing methodology reviews, performing detailed reviews of the assumptions and inputs used by the vendor to price individual securities, and price validation testing. Price validation testing is performed independent of the risk-taking function and can include corroborating the prices received from third-party vendors with prices from another third-party source, reviewing valuations of comparable instruments, comparison to internal valuations, or by reference to recent sales of similar securities. Securities not priced by one of the pricing vendors may be valued using a dealer quote.  Actively traded quoted market prices for investment securities available-for-sale, such as government agency bonds, corporate debt, and state and municipal securities, are not readily available. The Company's principal markets for its investment securities are the secondary institutional markets with an exit price that is predominantly reflective of bid level pricing in these markets. The third-party vendors use a variety of methods when pricing securities that incorporate relevant market data to arrive at an estimate of what a buyer in the marketplace would pay for a security under current market conditions.CLOs are initially valued by the provider using discounted cash flow models which consider inputs such as default correlation, credit spread, prepayment speed, conditional default rate and loss severity. The price produced by the model is then compared to recent trades for similar transactions. If there are differences between the model price and the market price, adjustments are made to the model so the final price approximates the market price. These investments are, therefore, considered Level 2. Certain of the Company's investments in asset-backed securities are valued based on their amortized cost, which is determined to be equal to the fair value of the securities. These securities have been classified as Level 2, as an active market does not exist for these securities; however, observable inputs, such as rate of return on each of the programs and observable yield curves, do exist. The Company's equity securities are priced using net asset value per share, since the price is unadjusted. These investments are, therefore, considered Level 1. The Company’s Level 3 investment assets are comprised of a sale-leaseback security. This investment is thinly traded, and the Company determined the estimated fair value of this security by evaluating pricing information from a combination of sources such as third-party pricing services, third-party broker quotes for certain securities and other independent third-party valuation sources. These quotes are benchmarked against similar securities that are more actively traded to assess the reasonableness of the estimated fair value. The fair market value estimate assigned to this security assumes liquidation in an orderly fashion and not under distressed circumstances. Significant unobservable inputs include third-party quotes and pricing on comparable securities that are more actively traded, as well as management-determined comparability adjustments. Significant increases (decreases) in any of those inputs in isolation would result in a significantly higher (lower) fair value measurement.Gains and losses on investments are recognized in the Condensed Consolidated Statements of Operations through Net gain on sale of investment securities.NOTE 14.  FAIR VALUE (continued)Loans Held for SaleThe fair values of LHFS are estimated using published forward agency prices to agency buyers such as the FNMA and the FHLMC. The majority of the residential LHFS portfolio is sold to these two agencies. The fair value is determined using current secondary market prices for portfolios with similar characteristics, adjusted for servicing values and market conditions. These loans are regularly traded in active markets, and observable pricing information is available from market participants. The prices are adjusted as necessary to include the embedded servicing value in the loans and to take into consideration the specific characteristics of certain loans that are priced based on the pricing of similar loans. These adjustments represent unobservable inputs to the valuation but are not considered significant given the relative insensitivity of the value to changes in these inputs to the fair value of the loans. Accordingly, residential mortgage LHFS are classified as Level 2. See further discussion below in the Fair Value Option for Financial Assets and Financial Liabilities section below. Mortgage servicing rightsThe model to value MSRs estimates the present value of the future net cash flows from mortgage servicing activities based on various assumptions. These cash flows include servicing and ancillary revenue, offset by the estimated costs of performing servicing activities. Significant assumptions used in the valuation of residential MSRs are CPR and the discount rate, reflective of a market participant's required return on an investment for similar assets. Other important valuation assumptions include market-based servicing costs and the anticipated earnings on escrow and similar balances held by the Company in the normal course of mortgage servicing activities. All of these assumptions are considered to be unobservable inputs. Historically, servicing costs and discount rates have been less volatile than CPR and earnings rates, both of which are directly correlated with changes in market interest rates. Increases in prepayment speeds, discount rates and servicing costs result in lower valuations of MSRs. Decreases in the anticipated earnings rate on escrow and similar balances result in lower valuations of MSRs. For each of these items, the Company makes assumptions based on current market information and future expectations. All of the assumptions are based on standards that the Company believes would be utilized by market participants in valuing mortgage servicing rights and are derived and/or benchmarked against independent public sources. Accordingly, MSRs are classified as Level 3. Gains and losses on MSRs are recognized on the Condensed Consolidated Statements of Operations through Mortgage banking income. See further discussion on MSRs in Note 7. Listed below are the most significant inputs that are utilized by the Company in the evaluation of residential MSRs:• A 10% and 20% increase in the CPR speed would decrease the fair value of the residential servicing asset by $4.7 million and $9.1 million, respectively, at September 30, 2013. •A 10% and 20% increase in the discount rate would decrease the fair value of the residential servicing asset by $5.8 million and $11.2 million, respectively, at September 30, 2013. Significant increases (decreases) in any of those inputs in isolation would result in a significantly higher (lower) fair value measurement. These sensitivity calculations are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of an adverse variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change. Prepayment estimates generally increase when market interest rates decline and decrease when market interest rates rise. Discount rates typically increase when market interest rates increase and/or credit and liquidity risks increase and decrease when market interest rates decline and/or credit and liquidity conditions improve. NOTE 14.  FAIR VALUE (continued)DerivativesThe valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable and unobservable market-based inputs. The fair value represents the estimated amount SHUSA would receive or pay to terminate the contracts or agreements, taking into account current interest rates, foreign exchange rates, equity prices and, when appropriate, the current creditworthiness of the counterparties. The Company incorporates credit valuation adjustments in the fair value measurement of its derivatives to reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurement of its derivatives. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings and guarantees. The Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy. Certain of the Company's derivatives utilize Level 3 inputs, which are primarily related to mortgage banking derivatives-interest rate lock commitments.  The discounted cash flow model is utilized to determine the fair value for the mortgage banking derivatives-interest rate lock commitments. The significant unobservable inputs for mortgage banking derivatives used in the fair value measurement of the reporting entity‘s loan commitments are "pull through" percentage and the MSR value that is inherent in the underlying loan value. The pull through percentage is an estimate of loan commitments that will result in closed loans. Significant increases (decreases) in any of these inputs in isolation would result in a significantly higher (lower) fair value measurement. Significant increases (decreases) in the fair value of a mortgage banking derivative asset (liability) results when the probability of funding increases (decreases). Significant increases (decreases) in the fair value of a mortgage loan commitment result when the embedded servicing value increases (decreases). Gains and losses related to derivatives affect various line items in the Condensed Consolidated Statements of Operations. See Note 9 for a discussion of derivatives activity.Level 3 Inputs - Significant Recurring Assets and Liabilities The following table presents quantitative information about the significant unobservable inputs within significant Level 3 recurring assets and liabilities.

FAIR VALUE (continued)Valuation Processes and Techniques - Financial Instruments The preceding tables present disclosures about the fair value of the Company's financial instruments. Those fair values for certain instruments are presented based upon subjective estimates of relevant market conditions at a specific point in time and information about each financial instrument. In cases in which quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. These techniques involve uncertainties resulting in variability in estimates affected by changes in assumptions and risks of the financial instruments at a certain point in time. Therefore, the derived fair value estimates presented above for certain instruments cannot be substantiated by comparison to independent markets. In addition, the fair values do not reflect any premium or discount that could result from offering for sale at one time an entity’s entire holding of a particular financial instrument, nor does it reflect potential taxes and the expenses that would be incurred in an actual sale or settlement. Accordingly, the aggregate fair value amounts presented above do not represent the underlying value of the Company.The following methods and assumptions were used to estimate the fair value of each class of financial instruments not measured at fair value on the Condensed Consolidated Balance Sheet:Cash and amounts due from depository institutions Cash and cash equivalents include cash and due from depository institutions, interest-bearing deposits in other banks, federal funds sold, and securities purchased under agreements to resell. The related fair value measurements have been classified as Level 1, as their carrying value approximates fair value due to the short-term nature of the asset. As of September 30, 2013 and December 31, 2012, the Company had $118.3 million and $488.5 million , respectively, of restricted cash. Restricted cash is related to cash restricted for investment purposes, cash posted for collateral purposes and cash advanced for loan purchases. Cash and cash equivalents, including restricted cash, have maturities of three months or less and, accordingly, the carrying amount of these instruments is deemed to be a reasonable estimate of fair value.Debentures of FHLB, FNMA, and FHLMC Other investments include debentures of the FHLB, FNMA and FHLMC. The related fair value measurements have generally been classified as Level 2, as carrying value approximates fair value. Loans held for investment, netThe fair values of loans are estimated based on groupings of similar loans, including but not limited to stratifications by type, interest rate, maturity, and borrower creditworthiness. Discounted future cash flow analyses are performed for these loans incorporating assumptions of current and projected voluntary prepayment speeds. Discount rates are determined using the Company's current origination rates on similar loans, adjusted for changes in current liquidity and credit spreads (if necessary). Because the current liquidity spreads are generally not observable in the market and the expected loss assumptions are based on the Company's experience, these are Level 3 valuations. Impaired loans are valued at fair value on a nonrecurring basis. See further discussion under Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis above. DepositsThe fair value of deposits with no stated maturity, such as non-interest-bearing demand deposits, interest-bearing demand deposit accounts, savings accounts and certain money market accounts, is equal to the amount payable on demand and does not take into account the significant value of the cost advantage and stability of the Company’s long-term relationships with depositors. The fair value of fixed-maturity certificates of deposit is estimated by discounting cash flows using currently offered rates for deposits of similar remaining maturities. The related fair value measurements have generally been classified as Level 1 for core deposits, as the carrying value approximates fair value due to the short-term nature of the liabilities. All other deposits are considered to be Level 2.  NOTE 14.  FAIR VALUE (continued)Borrowings and other debt obligationsFair value is estimated by discounting cash flows using rates currently available to the Company for other borrowings with similar terms and remaining maturities. Certain other debt obligation instruments are valued using available market quotes for similar instruments, which contemplates issuer default risk. The related fair value measurements have generally been classified as Level 2. Commitments to extend credit and standby letters of credit Commitments to extend credit and standby letters of credit include the value of unfunded lending commitments and standby letters of credit as well as the recorded liability for probable losses. The Company’s pricing of such financial instruments is based largely on credit quality and relationship, probability of funding and other requirements. Loan commitments often have fixed expiration dates and contain termination and other clauses which provide relief from funding in the event of significant deterioration in the credit quality of the customer. The rates and terms of the Company’s loan commitments and letters of credit are competitive with other financial institutions operating in markets served by the Company. The liability for probable losses is estimated by analyzing unfunded lending commitments and standby letters of credit for commercial customers and segregating by risk according to the Company's internal risk rating scale. These risk classifications, in conjunction with an analysis of historical loss experience, current economic conditions and performance trends within specific portfolio segments, and any other pertinent information, result in the estimation of the reserve for probable losses. These instruments and the related reserve are classified as Level 3. The Company believes that the carrying amounts, which are included in other liabilities, are reasonable estimates of the fair value of these financial instruments.Fair Value Option for Financial Assets and Financial Liabilities LHFSThe Company adopted the fair value option on residential mortgage loans classified as held for sale, which allows the Company to record the mortgage loan held-for-sale portfolio at fair market value versus the lower of cost, net of deferred fees, deferred origination costs and effects of hedge accounting, or market. The Company economically hedges its residential LHFS portfolio with forward sale agreements, which are reported at fair value. A lower of cost or market accounting treatment would not allow the Company to record the excess of the fair market value over book value, but would require the Company to record the corresponding reduction in value on the hedges. Both the loans and related hedges are carried at fair value, which reduces earnings volatility, as the amounts more closely offset, particularly when interest rates are declining.  The Company's residential LHFS portfolio had an aggregate fair value of $171.6 million at September 30, 2013. The contractual principal amount of these loans totaled $169.8 million at September 30, 2013. The difference in fair value compared to the principal balance of $1.8 million was recorded in mortgage banking income in the Condensed Consolidated Statement of Operations during the nine-month period ended September 30, 2013. Substantially all of these loans are current and none are in non-accrual status. Interest income on these loans is credited to interest income as earned. Residential MSRsAs of January 1, 2012, the Company elected to account for its existing portfolio of residential MSRs at fair value. Prior to this election, residential MSRs were accounted for using the amortization method subject to impairment. This election created greater flexibility with regards to any ongoing decisions relating to risk management of the asset by mitigating the effects of changes to the residential MSRs' fair value through the use of risk management instruments. The Company's residential MSRs had an aggregate fair value of $138.1 million at September 30, 2013. Changes in fair value totaling gains of $30.2 million were recorded in mortgage banking income in the Condensed Consolidated Statement of Operations during the nine-month period ended September 30, 2013. |
