Accounting Policies [Abstract]
Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Capitalized software Certain costs associated with software that is acquired, developed, or modified solely to meet internal needs are capitalized and amortized on a straight line basis over a period of 3 to 10 years. Direct costs of materials and services consumed in developing the software and internal payroll and payroll-related costs related to activities such as coding and testing the software are the types of costs capitalized. Capitalized costs for internal-use software are included in “Premises and equipment, net” in our balance sheet. Amortization of these costs is classified as “Technology and communications” expenses in our income statement. Additional accounting policies are more fully described in Note 1 in the “Notes to Consolidated Financial Statements” presented in our 2014 Annual Report on Form 10-K.

Although the Volcker Rule became effective on July 21, 2012 and the final rules became effective April 1, 2014, in connection with the adoption of the final rules on December 10, 2013 by the responsible agencies, the Federal Reserve issued an order extending the period during which institutions have to conform their activities and investments to the requirements of the Volcker Rule to July 21, 2015. In connection with conforming our activities to the Volcker Rule, including the establishment of a compliance program by July 21, 2015, we engaged in an enterprise wide review and established a cross functional working group. Our Volcker Rule conformance efforts included the establishment of a corporate-wide compliance program, required for banks with assets over $10 billion, which reviews and monitors Volcker Rule compliance on an on-going basis. A significant portion of our Volcker Rule conformance efforts included confirming that our activities are either excluded or exempted from the Volcker Rule. In areas where we have Volcker Rule applicability, including in connection with capital markets (e.g., risk mitigating hedging), residential lending (e.g., secondary mortgage originations) and certain other activities, Volcker Rule conformance is not anticipated to have a material impact. We have significant Volcker Rule applicability in connection with Collateralized Loan Obligations ("CLOs") held in our investment securities portfolio. The issuance of the final Volcker Rule restricts our ability to hold debt securities issued by CLOs where our investment in these debt securities is deemed to be an ownership interest in a CLO and the CLO itself does not qualify for an exclusion in the final rule for loan securitizations. On December 18, 2014, the Federal Reserve Board announced it would give banking entities until July 21, 2016 to conform investments in covered funds that were in place prior to December 31, 2013 ("legacy covered funds"). The Board also announced its intention to act next year to grant banking entities an additional one-year extension of the conformance period for legacy covered funds which together would extend until July 21, 2017 the time period for institutions to conform their ownership interests to the stated provisions of the final Volcker Rule. For our CLOs subject to the Volcker Rule in an unrealized loss position, we believe it is more likely than not that we will be able to hold these securities to recovery, which could be maturity as the Federal Reserve announcement extends the conformance period to July 2017 and we believe that other structural remedies are available to us to allow us to continue holding the bonds after the conformance period. In making the determination that the declines in fair value below amortized cost for the remainder of the portfolio were temporary, we considered some or all of the following factors: the period of time the securities were in an unrealized loss position, the percentage decline in comparison to the securities’ amortized cost, credit rating, the financial condition of the issuer and guarantor, where applicable, the delinquency or default rates of underlying collateral, projected collateral losses, projected cash flows and credit enhancement. If the level of credit enhancement is sufficient based on our expectations of future collateral losses, we conclude that we will receive all of the originally scheduled cash flows. If the present value of the cash flows indicates that we should not expect to recover the amortized cost basis of the security, we would consider the security to be other than temporarily impaired and write down the credit component of the unrealized loss through a charge to current period earnings. We do not intend to sell these securities in an unrealized loss position and it is not more likely than not that we will be required to sell these securities before the recovery of their amortized cost bases, which may be at maturity. Scheduled contractual maturities of our investment securities at September 30, 2015 were as follows: Amortized cost Fair value Debt securities: Within one year $ 248 $ 250 After one year through five years 628 635 After five years through ten years 737 717 After ten years 14 14 Total debt securities 1,627 1,617 Mortgage-backed securities 8,796 8,930 Collateralized loan obligations 1,113 1,118 Asset-backed securities 398 405 Other 22 22 $ 11,956 $ 12,093 While the contractual maturities of our mortgage-backed securities, collateralized loan obligations, asset-backed securities, and other securities generally exceed ten years , we expect the effective lives to be significantly shorter due to prepayments of the underlying loans and the nature of these securities. The duration of our investment securities portfolio decreased to 3.3 years at September 30, 2015 from 3.7 years at December 31, 2014 .

Receivables [Abstract]
Loans and Leases	Loans and Leases Overall Portfolio Our loan portfolio is made up of two segments, commercial loans and consumer loans. Those segments are further segregated between our loans initially accounted for under the amortized cost method (referred to as “originated” loans) and loans acquired (referred to as “acquired” loans). Our commercial loan portfolio segment includes both business and commercial real estate loans. Our consumer portfolio segment includes residential real estate, home equity, indirect auto, credit cards, and other consumer loans. Our loans and leases receivable consisted of the following at the dates indicated: September 30, 2015 December 31, 2014 Originated Acquired Total Originated Acquired Total Commercial: Real estate $ 6,284 $ 890 $ 7,174 $ 6,181 $ 1,050 $ 7,231 Construction 1,191 — 1,191 973 1 973 Business 5,862 169 6,031 5,430 345 5,775 Total commercial 13,338 1,060 14,397 12,584 1,395 13,979 Consumer: Residential real estate 2,289 1,057 3,346 2,096 1,257 3,353 Home equity 2,074 959 3,033 1,847 1,089 2,936 Indirect auto 2,331 — 2,331 2,166 — 2,166 Credit cards 306 — 306 324 — 324 Other consumer 254 — 254 278 — 278 Total consumer 7,254 2,015 9,269 6,711 2,347 9,058 Total loans and leases 20,592 3,075 23,666 19,296 3,742 23,037 Allowance for loan losses (233 ) (5 ) (239 ) (228 ) (6 ) (234 ) Total loans and leases, net $ 20,358 $ 3,069 $ 23,427 $ 19,067 $ 3,736 $ 22,803 As of September 30, 2015 and December 31, 2014 , we had a liability for unfunded loan commitments of $ 16 million . For the nine months ended September 30, 2015 , we recognized a negative provision for credit losses related to our unfunded loan commitments of $1 million . For the nine months ended September 30, 2014 we recognized a provision for credit losses related to our unfunded commitments of $1 million . Of the $3.0 billion home equity portfolio at September 30, 2015 and $2.9 billion at December 31, 2014 , $1.2 billion and $1.1 billion were in a first lien position at each period end, respectively. We hold or service the first lien loan for approximately 10% of the remainder of the home equity portfolio that was in a second lien position as of September 30, 2015 and December 31, 2014 . Acquired loan portfolios We have acquired loans in four acquisitions since January 1, 2009. All acquired loans were initially measured at fair value and subsequently accounted for under either Accounting Standards Codification Topic (“ASC”) 310-30 (Loans and Debt Securities Acquired with Deteriorated Credit Quality) or ASC 310-20 (Nonrefundable Fees and Other Costs.) The outstanding principal balance and the related carrying amount of our acquired loans included in our Consolidated Statements of Condition were as follows at the dates indicated: September 30, December 31, Credit impaired acquired loans evaluated individually for future credit losses Outstanding principal balance $ 5 $ 10 Carrying amount 5 6 Acquired loans evaluated collectively for future credit losses Outstanding principal balance 2,031 2,549 Carrying amount 1,994 2,496 Other acquired loans Outstanding principal balance 1,096 1,274 Carrying amount 1,076 1,240 Total acquired loans Outstanding principal balance 3,132 3,832 Carrying amount 3,075 3,742 The following table presents changes in the accretable yield, which includes income recognized from contractual interest cash flows, for the dates indicated. Acquired lines of credit accounted for under ASC 310-20 are not included in this table. Balance at January 1, 2014 $ (851 ) Net reclassifications from nonaccretable yield (5 ) Accretion 138 Other (1) 55 Balance at December 31, 2014 (663 ) Net reclassifications from nonaccretable yield (9 ) Accretion 80 Balance at September 30, 2015 $ (593 ) (1) Includes changes in expected cash flows from changes in interest rate and prepayment assumptions. During 2014 , we reduced our estimate of future cash flows on acquired loans to reflect our current outlook for prepayment speeds on these balances. The increase in prepayment speed assumptions reduced our accretable discount by $55 million in 2014 . These changes did not materially impact our interest income or net interest margin. Allowance for loan losses We establish our allowance for loan losses through a provision for credit losses based on our evaluation of the credit quality of our loan portfolio. We determined our allowance for loan losses by portfolio segment as defined above. For our originated loans, our allowance for loan losses consists of the following elements: (i) specific valuation allowances based on probable losses on specifically identified impaired loans; and (ii) valuation allowances based on net historical loan loss experience for similar loans with similar inherent risk characteristics and performance trends, adjusted, as appropriate for qualitative risk factors specific to respective loan types. We also maintain an allowance for loan losses on acquired loans when: (i) for loans accounted for under ASC 310-30, there is deterioration in credit quality subsequent to acquisition, and (ii) for loans accounted for under ASC 310-20, the inherent losses in the loans exceed the remaining credit discount recorded at the time of acquisition. Beginning in the second quarter of 2014, we raised our threshold for evaluating commercial loans individually for impairment from $200 thousand to $1 million . Impaired loans to commercial borrowers with outstandings less than $1 million are pooled and measured for impairment collectively. Additionally, all loans modified in a troubled debt restructuring ("TDR"), regardless of dollar size, are considered impaired. The impact of this change to our allowance for loan losses was not significant. This change is being implemented on a prospective basis, accordingly, prior period financial disclosures have not been revised. The following table presents the activity in our allowance for loan losses on originated loans and related recorded investment of the associated loans in our originated loan portfolio segment for the

Loans with no related allowance for loan losses have adequate collateral securing their carrying value and in some circumstances have been charged down to their current carrying value based on the fair value of the collateral. The recorded investment of our impaired loans, less any related allowance for loan losses, was 64% and 70% of the loans’ unpaid principal balance at September 30, 2015 and December 31, 2014 , respectively.

Period end nonperforming loans differed from the amount of total impaired loans as certain TDRs, which are considered impaired loans, were accruing interest because the borrower demonstrated its ability to satisfy the terms of the restructured loan for at least six consecutive payments. Also contributing to the difference are nonperforming commercial loans less than $1 million and nonperforming consumer loans, which are not considered impaired unless they have been modified in a TDR as they are evaluated collectively when determining the allowance for loan losses. The following table is a reconciliation between nonperforming loans and impaired loans at the dates indicated: Commercial Consumer Total September 30, 2015 Nonperforming loans $ 102 $ 109 $ 211 Plus: Accruing TDRs 48 13 61 Less: Smaller balance nonperforming loans evaluated collectively when determining the allowance for loan losses (34 ) (72 ) (106 ) Total impaired loans (1) $ 116 $ 51 $ 166 December 31, 2014: Nonperforming loans $ 106 $ 98 $ 204 Plus: Accruing TDRs 59 8 67 Less: Smaller balance nonperforming loans evaluated collectively when determining the allowance for loan losses (36 ) (71 ) (108 ) Total impaired loans (1) $ 128 $ 35 $ 163 (1) Includes nonperforming purchased credit impaired loans.

Acquired loans are considered to be accruing as we can reasonably estimate future cash flows on these acquired loans and we expect to fully collect the carrying value of these loans net of the allowance for acquired loan losses.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill The following table shows information regarding our goodwill for the nine months ended September 30, 2015 and the year ended December 31, 2014. Banking Financial Consolidated Balances at January 1, 2014 $ 2,381 $ 68 $ 2,449 Acquisitions — 1 1 Impairment (1,100 ) — (1,100 ) Balances at December 31, 2014 1,281 69 1,350 Disposal — (2 ) (2 ) Balances at September 30, 2015 $ 1,281 $ 67 $ 1,348 We perform our annual impairment test of goodwill on November 1st of each year or more often if events or circumstances have changed significantly from the annual test date. For the period ending September 30, 2014, we concluded it was more likely than not that the fair value of our Banking reporting unit was less than its carrying value including goodwill, given our current expectations regarding the macroeconomic and industry environment, including our view of future interest rates and our current stock price range. Accordingly, we performed a Step 1 review for possible goodwill impairment in advance of our annual impairment testing date. Under Step 1 of the goodwill impairment review, we calculated the fair value of the Banking reporting unit using a market approach, and compared the fair value to carrying value to identify potential impairment. Under Step 1, we determined that the carrying value of our Banking reporting unit exceeded its fair value. For Step 2, we compared the implied fair value of the Banking reporting unit's goodwill with the carrying amount of the goodwill for the Banking reporting unit. Based on our assessments under both Steps 1 and 2, we have recorded an impairment of our Banking reporting unit goodwill of $1.1 billion during the quarter ended September 30, 2014. When we performed our annual goodwill impairment assessment as of November 1, 2014, we concluded that our goodwill balance was not impaired.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We are a party to derivative financial instruments in the normal course of business to manage our own exposure to fluctuations in interest rates and to meet the needs of our customers. These financial instruments have been limited to interest rate swap agreements, which are entered into with counterparties that meet established credit standards and, where appropriate, contain master netting and collateral provisions protecting the party at risk. We believe that the credit risk inherent in all of our derivative contracts is minimal based on our credit standards and the netting and collateral provisions of the interest rate swap agreements. Our derivative positions include both instruments that are designated as hedging instruments and instruments that are customer related and not designated in hedging relationships. The following table presents information regarding our derivative financial instruments at the dates indicated: Asset derivatives Liability derivatives Notional Fair value (1) Notional Fair value (2) September 30, 2015 Derivatives designated as hedging instruments: Interest rate swap agreements $ — $ — $ 266 $ 7 Derivatives not designated as hedging instruments: Interest rate swap agreements 4,060 162 4,111 163 Total derivatives $ 4,060 $ 162 $ 4,377 $ 170 December 31, 2014 Derivatives designated as hedging instruments: Interest rate swap agreements $ 4 $ — $ 30 $ 2 Derivatives not designated as hedging instruments: Interest rate swap agreements 3,629 96 3,649 96 Total derivatives $ 3,633 $ 96 $ 3,679 $ 97 (1) Represents gross amounts, included in Other Assets in our Consolidated Statements of Condition. (2) Represents gross amounts, included in Other Liabilities in our Consolidated Statements of Condition. At September 30, 2015 , all of our interest rate swaps for which we had master netting positions with the counterparty were in a liability position. Accordingly, there was no offsetting in our Consolidated Statements of Condition at September 30, 2015 . Interest rate swaps for which we had master netting arrangements with the counterparty at December 31, 2014 were in a net liability position of $93 million . We offset $96 million of liabilities with $3 million of assets in our Consolidated Statement of Condition at December 31, 2014 related to these interest rate swaps and we did not include any cash collateral in the netting. We posted collateral for liability positions with a fair value of $239 million and $130 million at September 30, 2015 and December 31, 2014 , respectively. Derivatives designated in hedging relationships We designate interest rate swap agreements used to manage changes in the fair value of loans due to interest rate changes as fair value hedges. We have designated the risk of changes in the fair value of loans attributable to changes in the benchmark rate as the hedged risk. Accordingly, changes to the fair value of the hedged items attributable to a change in credit risk are excluded from our assessment of hedge effectiveness. The change in fair value of the derivatives, including both the effective and ineffective portions, is recognized in earnings and, so long as our fair value hedging relationships remain highly effective, such change is offset by the gain or loss due to the change in fair value of the loans attributable to the hedged risk. The net impact of the fair value hedging relationships on net income was not significant for the nine months ended September 30, 2015 and 2014 . We have entered into forward starting interest rate swaps to reduce our exposure to variability in interest-related cash outflows attributable to changes in forecasted LIBOR based borrowings. These derivative instruments are designated as cash flow hedges. We have designated the risk of changes in the amount of interest payment cash flows to be made during the term of the borrowings attributable to changes in the benchmark rate as the hedged risk. Accordingly, changes to the amount of interest payment cash flows for the hedged transactions attributable to a change in credit risk are excluded from our assessment of hedge effectiveness. Our interest rate swaps designated as cash flow hedges have maturities that correspond to the maturity of the forecasted hedged borrowing. Any gain or loss associated with the effective portion of our cash flow hedges is recognized in other comprehensive income and is subsequently reclassified into earnings in the period during which the hedged forecasted transactions affects earnings. Any gain or loss associated with the ineffective portion of our cash flow hedges, including ineffectiveness, is recognized immediately in earnings. At September 30, 2015 , there was a $3 million loss recognized in accumulated other comprehensive income related to these swaps. At September 30, 2015 , there was a $4 million loss recognized in accumulated other comprehensive income related to borrowings that were previously hedged using interest rate swaps that were classified as cash flow hedges. This amount will be reclassified out of accumulated other comprehensive income and into earnings over the remaining life of the hedged borrowings as an adjustment of yield. The following table presents certain information about amounts recognized for our derivative financial instruments designated in cash flow hedging relationships for the periods indicated. Three months ended September 30, Nine months ended September 30, Cash Flow Hedges 2015 2014 2015 2014 Interest rate swap agreements: Amount of (loss) on derivatives recognized in other comprehensive income, net of tax $ (2 ) $ — $ (2 ) $ — Amount of (loss) on derivatives reclassified from other comprehensive income to income (1) — — (1 ) (1 ) (1) Recognized in interest expense on borrowings in our Consolidated Statements of Operations. Derivatives not designated in hedging relationships In addition to our derivatives designated in hedging relationships, we act as an interest rate swap counterparty for certain commercial borrowers in the normal course of servicing our customers, which are accounted for at fair value. We manage our exposure to such interest rate swaps by entering into corresponding and offsetting interest rate swaps with third parties that mirror the terms of the interest rate swaps we have with the commercial borrowers. These positions (referred to as “customer swaps”) directly offset each other and our exposure is the positive fair value of the derivatives due to changes in credit risk of our commercial borrowers and third parties. We recognized revenue for this service that we provide our customers of $9 million and $7 million for the nine months ended September 30, 2015 and 2014 , respectively, included in Capital Markets income in our Consolidated Statements of Operations.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined 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. Current accounting guidance establishes a fair value hierarchy based on the transparency of inputs participants use to price an asset or liability. The fair value hierarchy prioritizes these inputs into the following three levels: Level 1 Inputs —Unadjusted quoted prices in active markets for identical assets or liabilities that are available at the measurement date. Level 2 Inputs —Inputs, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.), or inputs that are derived principally from or corroborated by market data through correlation or other means. Level 3 Inputs —Unobservable inputs for determining the fair value of the asset or liability and are based on the entity’s own estimates about the assumptions that market participants would use to price the asset or liability. A financial instrument’s categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Our valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While we believe our valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value. Assets and Liabilities Measured at Fair Value on a Recurring Basis Securities Available for Sale The fair value estimates of available for sale securities are based on quoted market prices of identical securities, where available (Level 1). However, as quoted prices of identical securities are not often available, the fair value estimate for almost our entire investment portfolio is based on quoted market prices of similar securities, adjusted for differences between the securities (Level 2). Adjustments may include amounts to reflect differences in underlying collateral, interest rates, estimated prepayment speeds, and counterparty credit quality. Where sufficient information is not available from the pricing services to produce a reliable valuation, we estimate fair value based on either broker quotes or internally developed models. We determine the fair value using third party pricing services, including brokers. As of September 30, 2015 , none of our investment securities were priced utilizing broker quotes. For details regarding our pricing process and sources, refer to Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Income-Critical Accounting Policies and Estimates.” Loans held for sale We have elected the fair value option for certain residential real estate loans held for sale as we believe the fair value measurement of such loans reduces certain timing differences in our Statement of Income and better aligns with our management of the portfolio from a business perspective. This election is made at the time of origination, on a loan by loan basis, and is irrevocable. The secondary market for securities backed by similar loan types is actively traded, which provides readily observable market pricing to be used as input for the estimate for the fair value of our loans. Accordingly, we have classified this fair value measurement as Level 2. Interest income on these loans is recognized in Interest Income—Loans and Leases in our Consolidated Statements of Operations. The table below presents information about our loans held for sale for which we elected the fair value option at the dates indicated: September 30, December 31, Fair value carrying amount $ 48 $ 35 Aggregate unpaid principal balance 46 34 Fair value carrying amount less aggregate unpaid principal balance $ 2 $ 1 Additionally, included in loans held for sale on our Consolidated Statements of Condition are $3 million and $5 million of commercial loans held for sale that are carried at the lower of cost or market at September 30, 2015 and December 31, 2014 , respectively. Derivatives We obtain fair value measurements of our interest rate swaps from a third party. The fair value measurements are determined using a market standard methodology of netting discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). Variable cash payments (or receipts) are based on an expectation of future interest rates derived from observable market interest rate curves. Credit valuation adjustments are incorporated to appropriately reflect our nonperformance risk as well as the counterparty’s nonperformance risk. The impact of netting and any applicable credit enhancements, such as bilateral collateral postings, thresholds, mutual puts, and guarantees are also considered in the fair value measurement. The fair value of our interest rate swaps was estimated using primarily Level 2 inputs. However, Level 3 inputs were used to determine credit valuation adjustments, such as estimates of current credit spreads to evaluate the likelihood of default. We have determined that the impact of these credit valuation adjustments was not significant to the overall valuation of our interest rate swaps. Therefore, we have classified the entire fair value of our interest rate swaps in Level 2 of the fair value hierarchy.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The following table summarizes our assets and liabilities measured at fair value on a nonrecurring basis for the periods indicated: Fair Value Measurements Total gains Total Level 1 Level 2 Level 3 (losses) Nine months ended September 30, 2015 Collateral dependent impaired loans $ 9 $ — $ 9 $ — $ — Nine months ended September 30, 2014 Collateral dependent impaired loans $ 11 $ — $ 10 $ 1 $ — Collateral Dependent Impaired Loans We record nonrecurring fair value adjustments to the carrying value of collateral dependent impaired loans when establishing the allowance for loan losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan less estimated costs to sell the collateral. When the fair value of such collateral, less costs to sell, is less than the carrying value of the loan, a specific allowance or charge off is recorded through a provision for credit losses. Real estate collateral is typically valued using independent appraisals that we review for acceptability, or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace and the related nonrecurring fair value measurements have been classified as Level 2. Under certain circumstances significant adjustments may be made to the appraised value due to the lack of direct marketplace information. Such adjustments are made as determined necessary in the judgment of our experienced senior credit officers to reflect current market conditions and current operating results for the specific collateral. When the fair value of collateral dependent impaired loans is based on appraisals containing significant adjustments, such collateral dependent impaired loans are classified as Level 3. We obtain new appraisals from an approved appraiser, in accordance with Interagency Appraisal and Evaluation Guidelines and internal policy. Appraisals or evaluations for assets securing substandard rated loans are usually completed within 90 days of the downgrade. An appraisal may be obtained more frequently when volatile or unusual market conditions exist that could affect the ultimate realization of the value of the real estate collateral. During the nine months ended September 30, 2015 , we recorded an increase of $0.4 million to our specific allowance as a result of adjusting the fair value of the collateral for certain collateral dependent impaired loans to $9 million at September 30, 2015 , which is included in our provision for credit losses. During the nine months ended September 30, 2014 we recorded an increase of $0.3 million to our specific allowance as a result of adjusting the fair value of the collateral for certain collateral dependent impaired loans to $11 million at September 30, 2014 , which is included in our provision for credit losses. Level 3 Assets Due to the lack of observable market data, we have classified our trust preferred securities, which are included in corporate debt securities and amounted to $4 million at September 30, 2015 and December 31, 2014 , in Level 3 of the fair value hierarchy. There were no changes in our trust preferred securities during the nine months ended September 30, 2015 and 2014 . As of September 30, 2015 and December 31, 2014 , the fair values of our trust preferred securities are based upon third party pricing without adjustment. Fair Value of Financial Instruments The carrying value and estimated fair value of our financial instruments, including those that are not measured and reported at fair value on a recurring basis or nonrecurring basis, at the dates indicated are as follows: September 30, 2015 December 31, 2014 Carrying value Estimated fair Fair value Carrying value Estimated fair Fair value Financial assets: Cash and cash equivalents $ 420 $ 420 1 $ 420 $ 420 1 Investment securities available for sale 5,726 5,726 1,2,3 (1) 5,915 5,915 1,2,3 (1) Investment securities held to maturity 6,280 6,367 2 5,942 5,964 2 Federal Home Loan Bank and Federal Reserve Bank common stock 373 373 2 412 412 2 Loans held for sale 51 51 2 40 40 2 Loans and leases, net 23,427 23,502 2,3 (2) 22,803 23,037 2,3 (2) Derivatives 162 162 2 93 93 2 Accrued interest receivable 107 107 2 101 101 2 Financial liabilities: Deposits $ 28,816 $ 28,834 2 $ 27,781 $ 27,793 2 Borrowings 5,870 5,878 2 6,206 6,215 2 Derivatives 170 170 2 94 94 2 Accrued interest payable 14 14 2 11 11 2 (1) For a detailed breakout of our investment securities available for sale, refer to our table of recurring fair value measurements. (2) Loans and leases classified as level 2 are made up of $9 million and $10 million of collateral dependent impaired loans without significant adjustments made to appraised values at September 30, 2015 and December 31, 2014 , respectively. All other loans and leases are classified as level 3. Our fair value estimates are based on our existing on and off balance sheet financial instruments without attempting to estimate the value of any anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on our fair value estimates and have not been considered in these estimates. Our fair value estimates are made as of the dates indicated, based on relevant market information and information about the financial instruments, including our judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in our assumptions could significantly affect the estimates. Our fair value estimates, methods, and assumptions are set forth below for each type of financial instrument. The method of estimating the fair value of the financial instruments disclosed in the table above does not necessarily incorporate the exit price concept used to record financial instruments at fair value in our Consolidated Statements of Condition or when measuring goodwill for impairment. Cash and Cash Equivalents The carrying value of our cash and cash equivalents approximates fair value because these instruments have original maturities of three months or less. Investment Securities The fair value estimates of securities are based on quoted market prices of identical securities, where available. However, as quoted prices of identical securities are not often available, the fair value estimate for almost our entire investment portfolio is based on quoted market prices of similar securities, adjusted for differences between the securities. Adjustments may include amounts to reflect differences in underlying collateral, interest rates, estimated prepayment speeds, and counterparty credit quality. Federal Home Loan Bank and Federal Reserve Bank Common Stock The carrying value of our Federal Home Loan Bank and Federal Reserve Bank common stock, which are non-marketable equity investments, approximates fair value. Loans and Leases Our variable rate loans reprice as the associated rate index changes. The calculation of fair value for our variable rate loans is driven by the comparison between the loan’s margin and the prevailing margin observed in the market at the time of the valuation. Any caps and floors embedded in the loan’s pricing structure are also incorporated into the fair value. We calculated the fair value of our fixed-rate loans and leases by discounting scheduled cash flows through the estimated maturity using credit adjusted period end origination rates. Our estimate of maturity is based on the contractual cash flows adjusted for prepayment estimates based on current economic and lending conditions. Accrued Interest Receivable and Accrued Interest Payable The carrying value of accrued interest receivable and accrued interest payable approximates fair value. Deposits The fair value of our deposits with no stated maturity, such as savings and checking, as well as mortgagors’ payments held in escrow, is equal to the amount payable on demand. The fair value of our certificates of deposit is based on the discounted value of contractual cash flows, using the period end rates offered for deposits of similar remaining maturities. Borrowings The fair value of our borrowings is calculated by discounting scheduled cash flows through the estimated maturity using period end market rates for borrowings of similar remaining maturities. Commitments The fair value of our commitments to extend credit, standby letters of credit, and financial guarantees are not included in the above table as the carrying value generally approximates fair value. These instruments generate fees that approximate those currently charged to originate similar commitments.

[1]	Includes credit card loans, loans that have matured and are in the process of collection, and acquired loans that were originally recorded at fair value upon acquisition. Acquired loans are considered to be accruing as we can reasonably estimate future cash flows on these acquired loans and we expect to fully collect the carrying value of these loans net of the allowance for acquired loan losses. Therefore, we are accreting the difference between the carrying value of these loans and their expected cash flows into interest income.
