Notes to Consolidated Financial Statements (unaudited)
Comerica Incorporated and Subsidiaries

NOTE 1 - BASIS OF PRESENTATION AND ACCOUNTING POLICIES
Organization
The accompanying unaudited consolidated financial statements were prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation were included. The results of operations for the six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. Certain items in prior periods were reclassified to conform to the current presentation. For further information, refer to the consolidated financial statements and footnotes thereto included in the Annual Report of Comerica Incorporated and Subsidiaries (the Corporation) on Form 10-K for the year ended December 31, 2014.
Revenue Recognition
In the first quarter 2015, the Corporation entered into a new contract for an existing debit card program. Guidance provided in Accounting Standards Code 605-45, "Principal Agent Considerations," indicates whether revenue should be reported gross or net for this type of arrangement. Management assessed various principal versus agent indicators provided in the guidance and concluded that the Corporation bears the risks and rewards of providing the services for the card program based on the new contract terms and, therefore, gross presentation of revenues and expenses is appropriate. This change in presentation resulted in increases of $44 million and $88 million to both "card fees" in noninterest income and "outside processing fee expense" in noninterest expenses for the three- and six-month periods ended June 30, 2015, respectively.
Recently Adopted Accounting Pronouncements
Effective January 1, 2015, the Corporation prospectively adopted Accounting Standards Update (ASU) No. 2014-04, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure,” (ASU 2014-04), which clarifies when an in-substance foreclosure or repossession of residential real estate property occurs, requiring a creditor to reclassify the loan to other real estate. According to ASU 2014-04, a consumer mortgage loan should be reclassified to other real estate either upon the creditor obtaining legal title to the real estate collateral or when the borrower voluntarily conveys all interest in the real estate property to the creditor through a deed in lieu of foreclosure or similar legal agreement. ASU 2014-04 also clarifies that a creditor that has obtained legal title to a foreclosed property should not delay reclassification when a borrower has a legal right of redemption for a period of time. The Corporation's existing accounting treatment is consistent with the new guidance, and therefore the adoption of ASU 2014-04 had no impact to the Corporation's financial condition and results of operations. Disclosures required by ASU 2014-04 are provided in Note 4.
Also effective January 1, 2015, the Corporation prospectively adopted ASU No. 2014-12, “Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” (ASU 2014-12). The new guidance requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The Corporation's current accounting treatment of performance conditions for employees who are or become retirement eligible prior to the achievement of the performance target is consistent with ASU 2014-12, and as such the adoption of ASU 2014-12 had no impact to the Corporation’s financial condition and results of operations.
In the second quarter 2015, the Corporation early adopted ASU 2015-03, "Interest - Imputation of Interest (Subtopic 835-30)," which amends the presentation of debt issuance costs in the balance sheet as a direct deduction from the carrying amount of the related debt liability rather than as a deferred charge. The new guidance was retrospectively applied, which resulted in a decrease of $4 million to both "accrued income and other assets" and "medium- and long-term debt" on the consolidated balance sheets as of December 31, 2014. Unamortized debt issuance costs deducted from the carrying amount of medium- and long-term debt totaled $6 million at June 30, 2015.
Pending Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” (ASU 2014-09), which is intended to improve and converge the financial reporting requirements for revenue contracts with customers. Previous GAAP comprised broad revenue recognition concepts along with numerous industry-specific requirements. The new guidance establishes a five-step model which entities must follow to recognize revenue and removes inconsistencies and weaknesses in existing guidance. The guidance under ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2017 and must be retrospectively applied. Entities will have the option of presenting

prior periods as impacted by the new guidance or presenting the cumulative effect of initial application along with supplementary disclosures. Early adoption is permitted, but not before annual and interim periods beginning after December 15, 2016. The Corporation is currently evaluating the impact of adopting ASU 2014-09.
In February 2015, the FASB issued ASU 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis," (ASU 2015-02), which makes targeted amendments to the considerations applied by reporting entities when determining if a legal entity should be consolidated, including placing more emphasis on risk of loss when determining a controlling financial interest. Low-income housing tax credit investments that meet the criteria for the proportional amortization method are not impacted by these amendments. ASU 2015-02 is effective for annual and interim periods beginning after December 15, 2015, and must be retrospectively applied. Early adoption is permitted. The Corporation is currently evaluating the impact of adopting ASU 2015-02.
In April 2015, the FASB issued ASU 2015-05, "Goodwill and Other - Internal-Use Software (Subtopic 350-40)," (ASU 2015-05), which defines specific criteria entities must apply to determine if a cloud computing arrangement includes an in-substance software license. The result of the assessment will direct the entity to apply either software licensing or service contract guidance to record the related costs. ASU 2015-05 is effective for annual and interim periods beginning after December 15, 2015, and can be prospectively or retrospectively applied. Early adoption is permitted. The Corporation does not expect the adoption to have a material effect on its financial condition and results of operations.
In May 2015, the FASB issued ASU 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent),” (ASU 2015-07) which amends disclosure requirements for entities that utilize net asset value per share (or its equivalent) to measure fair value as a practical expedient. The update eliminates the requirement to classify these investments within the fair value hierarchy and instead requires disclosure of sufficient information about these investments to permit reconciliation of the fair value of investments categorized within the fair value hierarchy to the investments presented in the consolidated balance sheet. ASU 2015-07 is effective for annual and interim periods beginning after December 15, 2015 and must be applied retrospectively. Early adoption is permitted. The adoption of ASU 2015-07 will have no impact on the Corporation's financial condition or results of operations.
NOTE 2 – FAIR VALUE MEASUREMENTS
The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Corporation uses present value techniques and other valuation methods to estimate the fair values of its financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used.
Trading securities, investment securities available-for-sale, derivatives and deferred compensation plan liabilities are recorded at fair value on a recurring basis. Additionally, from time to time, the Corporation may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as impaired loans, other real estate (primarily foreclosed property), nonmarketable equity securities and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve write-downs of individual assets or application of lower of cost or fair value accounting.
Refer to Note 1 to the consolidated financial statements in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2014 for further information about the fair value hierarchy, descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value, as well as a description of the methods and significant assumptions used to estimate fair value disclosures for financial instruments not recorded at fair value in their entirety on a recurring basis. When credit valuation adjustments are significant to the overall fair value of a derivative, the Corporation classifies the over-the-counter derivative valuation in Level 3 of the fair value hierarchy; otherwise, over-the-counter derivative valuations are classified in Level 2.

ASSETS AND LIABILITIES RECORDED AT FAIR VALUE ON A NONRECURRING BASIS
The Corporation may be required, from time to time, to record certain assets and liabilities at fair value on a nonrecurring basis. These include assets that are recorded at the lower of cost or fair value that were recognized at fair value below cost at the end of the period. All assets recorded at fair value on a nonrecurring basis were classified as Level 3 at June 30, 2015 and December 31, 2014 and are presented in the following table. No liabilities were recorded at fair value on a nonrecurring basis at June 30, 2015 and December 31, 2014.

Level 3 assets recorded at fair value on a nonrecurring basis at June 30, 2015 and December 31, 2014 included loans for which a specific allowance was established based on the fair value of collateral and other real estate for which fair value of the properties was less than the cost basis. For both asset classes, the unobservable inputs were the additional adjustments applied by management to the appraised values to reflect such factors as non-current appraisals and revisions to estimated time to sell. These adjustments are determined based on qualitative judgments made by management on a case-by-case basis and are not quantifiable inputs, although they are used in the determination of fair value.
The following table presents quantitative information related to the significant unobservable inputs utilized in the Corporation's Level 3 recurring fair value measurement as of June 30, 2015 and December 31, 2014. The Corporation's Level 3 recurring fair value measurements include auction-rate securities where fair value is determined using an income approach based on a discounted cash flow model. The inputs in the table below reflect management's expectation of continued illiquidity in the secondary auction-rate securities market due to a lack of market activity for the issuers remaining in the portfolio, a lack of market incentives for issuer redemptions, and the expectation for a continuing low interest rate environment. The June 30, 2015 workout periods reflect management's view that short-term interest rates could begin to rise in 2015.

ESTIMATED FAIR VALUES OF FINANCIAL INSTRUMENTS NOT RECORDED AT FAIR VALUE ON A RECURRING BASIS
The Corporation typically holds the majority of its financial instruments until maturity and thus does not expect to realize many of the estimated fair value amounts disclosed. The disclosures also do not include estimated fair value amounts for items that are not defined as financial instruments, but which have significant value. These include such items as core deposit intangibles, the future earnings potential of significant customer relationships and the value of trust operations and other fee generating businesses. The Corporation believes the imprecision of an estimate could be significant.
The carrying amount and estimated fair value of financial instruments not recorded at fair value in their entirety on a recurring basis on the Corporation’s consolidated balance sheets are as follows:

(b)
Residential mortgage-backed securities issued and/or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises.
(c)
Auction-rate securities.
At June 30, 2015, the Corporation had 112 securities in an unrealized loss position with no credit impairment, including 93 residential mortgage-backed securities, 17 state and municipal auction-rate securities, one corporate auction-rate debt security and one U.S. Treasury security. As of June 30, 2015, approximately 93 percent of the aggregate par value of auction-rate securities have been redeemed or sold since acquisition, of which approximately 92 percent were redeemed at or above cost. The unrealized losses for these securities resulted from changes in market interest rates and liquidity. The Corporation ultimately expects full collection of the carrying amount of these securities, does not intend to sell the securities in an unrealized loss position, and it is not more-likely-than-not that the Corporation will be required to sell the securities in an unrealized loss position prior to recovery of amortized cost. The Corporation does not consider these securities to be other-than-temporarily impaired at June 30, 2015.

The following table summarizes the amortized cost and fair values of debt securities by contractual maturity. Securities with multiple maturity dates are classified in the period of final maturity. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Included in the contractual maturity distribution in the table above were residential mortgage-backed securities available-for-sale with total amortized cost and fair value of $7.2 billion and $7.3 billion, respectively, and residential mortgage-backed securities held-to-maturity with a total amortized cost and fair value of $2.0 billion and $1.9 billion, respectively. The actual cash flows of mortgage-backed securities may differ from contractual maturity as the borrowers of the underlying loans may exercise prepayment options.
At June 30, 2015, investment securities with a carrying value of $2.8 billion were pledged where permitted or required by law to secure $2.2 billion of liabilities, primarily public and other deposits of state and local government agencies and derivative instruments.

(a)
Includes all loans not included in the categories of special mention, substandard or nonaccrual.
(b)
Special mention loans are accruing loans that have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date.
(c)
Substandard loans are accruing loans that have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans also are distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. This category is generally consistent with the "substandard" category as defined by regulatory authorities.
(d)
Nonaccrual loans are loans for which the accrual of interest has been discontinued. For further information regarding nonaccrual loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies - on page F-55 in the Corporation's 2014 Annual Report. A significant majority of nonaccrual loans are generally consistent with the "substandard" category and the remainder are generally consistent with the "doubtful" category as defined by regulatory authorities.
(e)
Primarily loans to real estate developers.
(f)
Primarily loans secured by owner-occupied real estate.

(a)

(b)
Primarily loans to real estate developers.
(c)
Primarily loans secured by owner-occupied real estate.
Commitments to lend additional funds to borrowers whose terms have been modified in TDRs were insignificant at June 30, 2015 and $3 million at December 31, 2014.
The majority of the modifications considered to be TDRs that occurred during the six months ended June 30, 2015 and 2014 were principal deferrals. The Corporation charges interest on principal balances outstanding during deferral periods. Additionally, none of the modifications involved forgiveness of principal. As a result, the current and future financial effects of the recorded balance of loans considered to be TDRs that were restructured during the six months ended June 30, 2015 and 2014 were insignificant.
On an ongoing basis, the Corporation monitors the performance of modified loans to their restructured terms. In the event of a subsequent default, the allowance for loan losses continues to be reassessed on the basis of an individual evaluation of the loan.

The following table presents information regarding the recorded balance at June 30, 2015 and 2014 of loans modified by principal deferral during the twelve-month periods ended June 30, 2015 and 2014, and those principal deferrals which experienced a subsequent default during the three- and six-month periods ended June 30, 2015 and 2014. For principal deferrals, incremental deterioration in the credit quality of the loan, represented by a downgrade in the risk rating of the loan, for example, due to missed interest payments or a reduction of collateral value, is considered a subsequent default.

(c)
Includes bankruptcy loans for which the court has discharged the borrower's obligation and the borrower has not reaffirmed the debt.
During the twelve-month periods ended June 30, 2015 and 2014, loans with a carrying value of $2 million and $5 million, respectively, were modified by interest rate reduction. For reduced-rate loans a subsequent payment default is defined in terms of delinquency, when a principal or interest payment is 90 days past due. There were no subsequent payment defaults of reduced-rate loans during the three- and six-month periods ended June 30, 2015 and 2014.
Purchased Credit-Impaired Loans
Acquired loans are initially recorded at fair value with no carryover of any allowance for loan losses. Loans acquired with evidence of credit quality deterioration at acquisition for which it was probable that the Corporation would not be able to collect all contractual amounts due were accounted for as PCI loans. The Corporation aggregated the acquired PCI loans into pools of loans based on common risk characteristics.
No allowance for loan losses was required on the acquired PCI loan pools at both June 30, 2015 and December 31, 2014. The carrying amount of acquired PCI loans included in the consolidated balance sheet and the related outstanding balance at June 30, 2015 and December 31, 2014 were as follows.

NOTE 5 - DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS
In the normal course of business, the Corporation enters into various transactions involving derivative and credit-related financial instruments to manage exposure to fluctuations in interest rate, foreign currency and other market risks and to meet the financing needs of customers (customer-initiated derivatives). These financial instruments involve, to varying degrees, elements of market and credit risk. Market and credit risk are included in the determination of fair value.
Market risk is the potential loss that may result from movements in interest rates, foreign currency exchange rates or energy commodity prices that cause an unfavorable change in the value of a financial instrument. The Corporation manages this risk by establishing monetary exposure limits and monitoring compliance with those limits. Market risk inherent in interest rate and energy contracts entered into on behalf of customers is mitigated by taking offsetting positions, except in those circumstances when the amount, tenor and/or contract rate level results in negligible economic risk, whereby the cost of purchasing an offsetting contract is not economically justifiable. The Corporation mitigates most of the inherent market risk in foreign exchange contracts entered into on behalf of customers by taking offsetting positions and manages the remainder through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and reviewed quarterly. Market risk inherent in derivative instruments held or issued for risk management purposes is typically offset by changes in the fair value of the assets or liabilities being hedged.
Credit risk is the possible loss that may occur in the event of nonperformance by the counterparty to a financial instrument. The Corporation attempts to minimize credit risk arising from customer-initiated derivatives by evaluating the creditworthiness of each customer, adhering to the same credit approval process used for traditional lending activities and obtaining collateral as deemed necessary. Derivatives with dealer counterparties are either cleared through a clearinghouse or settled directly with a single counterparty. For derivatives settled directly with dealer counterparties, the Corporation utilizes counterparty risk limits and monitoring procedures as well as master netting arrangements and bilateral collateral agreements to facilitate the management of credit risk. Master netting arrangements effectively reduce credit risk by permitting settlement of positive and negative positions and offset cash collateral held with the same counterparty on a net basis. Bilateral collateral agreements require daily exchange of cash or highly rated securities issued by the U.S. Treasury or other U.S. government entities to collateralize amounts due to either party beyond certain risk limits. At June 30, 2015, counterparties with bilateral collateral agreements had pledged $128 million of marketable investment securities and deposited $254 million of cash with the Corporation to secure the fair value of contracts in an unrealized gain position, and the Corporation had posted $3 million of cash as collateral for contracts in an unrealized loss position. For those counterparties not covered under bilateral collateral agreements, collateral is obtained, if deemed necessary, based on the results of management’s credit evaluation of the counterparty. Collateral varies, but may include cash, investment securities, accounts receivable, equipment or real estate. Included in the fair value of derivative instruments are credit valuation adjustments reflecting counterparty credit risk. These adjustments are determined by applying a credit spread for the counterparty or the Corporation, as appropriate, to the total expected exposure of the derivative. At June 30, 2015, the Corporation had no derivative instruments with credit-risk-related contingent features that were in a liability position.
Derivative Instruments
Derivative instruments utilized by the Corporation are negotiated over-the-counter and primarily include swaps, caps and floors, forward contracts and options, each of which may relate to interest rates, energy commodity prices or foreign currency exchange rates. Swaps are agreements in which two parties periodically exchange cash payments based on specified indices applied to a specified notional amount until a stated maturity. Caps and floors are agreements which entitle the buyer to receive cash payments based on the difference between a specified reference rate or price and an agreed strike rate or price, applied to a specified notional amount until a stated maturity. Forward contracts are over-the-counter agreements to buy or sell an asset at a specified future date and price. Options are similar to forward contracts except the purchaser has the right, but not the obligation, to buy or sell the asset during a specified period or at a specified future date.
Over-the-counter contracts are tailored to meet the needs of the counterparties involved and, therefore, contain a greater degree of credit risk and liquidity risk than exchange-traded contracts, which have standardized terms and readily available price information. The Corporation reduces exposure to market and liquidity risks from over-the-counter derivative instruments entered

into for risk management purposes, and transactions entered into to mitigate the market risk associated with customer-initiated transactions, by conducting hedging transactions with investment grade domestic and foreign financial institutions and subjecting counterparties to credit approvals, limits and collateral monitoring procedures similar to those used in making other extensions of credit. In addition, certain derivative contracts executed bilaterally with a dealer counterparty in the over-the-counter market are cleared through a clearinghouse, whereby the clearinghouse becomes the counterparty to the transaction.

(a)
Notional or contractual amounts, which represent the extent of involvement in the derivatives market, are used to determine the contractual cash flows required in accordance with the terms of the agreement. These amounts are typically not exchanged, significantly exceed amounts subject to credit or market risk and are not reflected in the consolidated balance sheets.
(b)
Net derivative assets are included in “accrued income and other assets” and net derivative liabilities are included in “accrued expenses and other liabilities” on the consolidated balance sheets. Included in the fair value of net derivative assets and net derivative liabilities are credit valuation adjustments reflecting counterparty credit risk and credit risk of the Corporation. The fair value of net derivative assets included credit valuation adjustments for counterparty credit risk of $4 million and $2 million at June 30, 2015 and December 31, 2014, respectively.

Risk Management
As an end-user, the Corporation employs a variety of financial instruments for risk management purposes, including cash instruments, such as investment securities, as well as derivative instruments. Activity related to these instruments is centered predominantly in the interest rate markets and mainly involves interest rate swaps. Various other types of instruments also may be used to manage exposures to market risks, including interest rate caps and floors, total return swaps, foreign exchange forward contracts and foreign exchange swap agreements.
The Corporation entered into interest rate swap agreements for interest rate risk management purposes. These interest rate swap agreements effectively modify the Corporation’s exposure to interest rate risk by converting fixed-rate debt to a floating rate. These agreements involve the receipt of fixed-rate interest amounts in exchange for floating-rate interest payments over the life of the agreement, without an exchange of the underlying principal amount. Risk management fair value interest rate swaps generated net interest income of $16 million and $18 million for the three months ended June 30, 2015 and 2014, respectively, and $34 million and $36 million for the six months ended June 30, 2015 and 2014, respectively. The Corporation recognized $2 million and an insignificant amount of net losses for the three months ended June 30, 2015 and 2014, respectively, and $1 million and an insignificant amount of net losses for the six months ended June 30, 2015 and 2014, respectively, in "other noninterest income" in the consolidated statements of comprehensive income for the ineffective portion of risk management derivative instruments designated as fair value hedges of fixed-rate debt.
Foreign exchange rate risk arises from changes in the value of certain assets and liabilities denominated in foreign currencies. The Corporation employs spot and forward contracts in addition to swap contracts to manage exposure to these and other risks. The Corporation recognized an insignificant amount of net losses on risk management derivative instruments used as economic hedges in "other noninterest income" in the consolidated statements of comprehensive income for each of the three- and six-month periods ended June 30, 2015 and 2014.
 The following table summarizes the expected weighted average remaining maturity of the notional amount of risk management interest rate swaps and the weighted average interest rates associated with amounts expected to be received or paid on interest rate swap agreements as of June 30, 2015 and December 31, 2014.

Variable rates paid on receive fixed swaps are based on six-month LIBOR rates in effect at June 30, 2015 and December 31, 2014.
Management believes these hedging strategies achieve the desired relationship between the rate maturities of assets and funding sources which, in turn, reduce the overall exposure of net interest income to interest rate risk, although there can be no assurance that such strategies will be successful.
Customer-Initiated and Other
The Corporation enters into derivative transactions at the request of customers and generally takes offsetting positions with dealer counterparties to mitigate the inherent market risk. Income primarily results from the spread between the customer derivative and the offsetting dealer position.
For customer-initiated foreign exchange contracts where offsetting positions have not been taken, the Corporation manages the remaining inherent market risk through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and reviewed quarterly. For those customer-initiated derivative contracts which were not offset or where the Corporation holds a speculative position within the limits described above, the Corporation recognized $1 million of net gains in “other noninterest income” in the consolidated statements of comprehensive income for the three- and six-month periods ended June 30, 2015 and an insignificant amount for the three- and six-month periods ended June 30, 2014.

The Corporation maintains an allowance to cover probable credit losses inherent in lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. At June 30, 2015 and December 31, 2014, the allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated balance sheets, was $50 million and $41 million, respectively.
Unused Commitments to Extend Credit
Commitments to extend credit are legally binding agreements to lend to a customer, provided there is no violation of any condition established in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many commitments expire without being drawn upon, the total contractual amount of commitments does not necessarily represent future cash requirements of the Corporation. Commercial and other unused commitments are primarily variable rate commitments. The allowance for credit losses on lending-related commitments included $33 million and $30 million at June 30, 2015 and December 31, 2014, respectively, for probable credit losses inherent in the Corporation’s unused commitments to extend credit.
Standby and Commercial Letters of Credit
Standby letters of credit represent conditional obligations of the Corporation which guarantee the performance of a customer to a third party. Standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Commercial letters of credit are issued to finance foreign or domestic trade transactions. These contracts expire in decreasing amounts through the year 2022. The Corporation may enter into participation arrangements with third parties that effectively reduce the maximum amount of future payments which may be required under standby and commercial letters of credit. These risk participations covered $292 million and $316 million, respectively, of the $3.8 billion and $4.0 billion standby and commercial letters of credit outstanding at June 30, 2015 and December 31, 2014, respectively.
The carrying value of the Corporation’s standby and commercial letters of credit, included in “accrued expenses and other liabilities” on the consolidated balance sheets, totaled $61 million at June 30, 2015, including $44 million in deferred fees and $17 million in the allowance for credit losses on lending-related commitments. At December 31, 2014, the comparable amounts were $55 million, $44 million and $11 million, respectively.

Other Credit-Related Financial Instruments
The Corporation enters into credit risk participation agreements, under which the Corporation assumes credit exposure associated with a borrower’s performance related to certain interest rate derivative contracts. The Corporation is not a party to the interest rate derivative contracts and only enters into these credit risk participation agreements in instances in which the Corporation is also a party to the related loan participation agreement for such borrowers. The Corporation manages its credit risk on the credit risk participation agreements by monitoring the creditworthiness of the borrowers, which is based on the normal credit review process had it entered into the derivative instruments directly with the borrower. The notional amount of such credit risk participation agreement reflects the pro-rata share of the derivative instrument, consistent with its share of the related participated loan. As of June 30, 2015 and December 31, 2014, the total notional amount of the credit risk participation agreements was approximately $620 million and $598 million, respectively, and the fair value, included in customer-initiated interest rate contracts recorded in "accrued expenses and other liabilities" on the consolidated balance sheets, was insignificant for each period. The maximum estimated exposure to these agreements, as measured by projecting a maximum value of the guaranteed derivative instruments, assuming 100 percent default by all obligors on the maximum values, was approximately $8 million and $7 million at June 30, 2015 and December 31, 2014, respectively. In the event of default, the lead bank has the ability to liquidate the assets of the borrower, in which case the lead bank would be required to return a percentage of the recouped assets to the participating banks. As of June 30, 2015, the weighted average remaining maturity of outstanding credit risk participation agreements was 2.5 years.
In 2008, the Corporation sold its remaining ownership of Visa Class B shares and entered into a derivative contract. Under the terms of the derivative contract, the Corporation will compensate the counterparty primarily for dilutive adjustments made to the conversion factor of the Visa Class B shares to Class A shares based on the ultimate outcome of litigation involving Visa. Conversely, the Corporation will be compensated by the counterparty for any increase in the conversion factor from anti-dilutive adjustments. The notional amount of the derivative contract was equivalent to approximately 780,000 Visa Class B shares. The fair value of the derivative liability, included in "accrued expenses and other liabilities" on the consolidated balance sheets, was $1 million at both June 30, 2015 and December 31, 2014, respectively.
NOTE 6 - VARIABLE INTEREST ENTITIES (VIEs)
The Corporation evaluates its interest in certain entities to determine if these entities meet the definition of a VIE and whether the Corporation is the primary beneficiary and should consolidate the entity based on the variable interests it held both at inception and when there is a change in circumstances that requires a reconsideration.
The Corporation holds ownership interests in funds in the form of limited partnerships or limited liability companies (LLCs) investing in affordable housing projects that qualify for the low-income housing tax credit (LIHTC). The Corporation also directly invests in limited partnerships and LLCs which invest in community development projects which generate similar tax credits to investors. As an investor, the Corporation obtains income tax credits and deductions from the operating losses of these tax credit entities. These tax credit entities meet the definition of a VIE; however, the Corporation is not the primary beneficiary of the entities, as the general partner or the managing member has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses or the right to receive benefits that could be significant to the entities. While the partnership/LLC agreements allow the limited partners/investor members, through a majority vote, to remove the general partner/managing member, this right is not deemed to be substantive as the general partner/managing member can only be removed for cause.
The Corporation accounts for its interests in LIHTC entities using the proportional amortization method. Exposure to loss as a result of the Corporation’s involvement with LIHTC entities at June 30, 2015 was limited to approximately $389 million. Ownership interests in other community development projects which generate similar tax credits to investors (other tax credit entities) are accounted for under either the cost or equity method. Exposure to loss as a result of the Corporation's involvement in other tax credit entities at June 30, 2015 was limited to approximately $10 million.
Investment balances, including all legally binding commitments to fund future investments, are included in “accrued income and other assets” on the consolidated balance sheets. A liability is recognized in “accrued expenses and other liabilities”

on the consolidated balance sheets for all legally binding unfunded commitments to fund tax credit entities ($130 million at June 30, 2015). Amortization and other write-downs of LIHTC investments are presented on a net basis as a component of the "provision for income taxes" on the consolidated statements of comprehensive income, while amortization and write-downs of other tax credit investments are recorded in “other noninterest income." The income tax credits and deductions are recorded as a reduction of income tax expense and a reduction of federal income taxes payable.
The Corporation provided no financial or other support that was not contractually required to any of the above VIEs during the six months ended June 30, 2015 and 2014.

Comerica Bank, a wholly-owned subsidiary of the Corporation (the Bank), is a member of the FHLB, which provides short- and long-term funding to its members through advances collateralized by real estate-related assets. Actual borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. At June 30, 2015, $14 billion of real estate-related loans were pledged to the FHLB as blanket collateral for potential future borrowings of approximately $6 billion.

NOTE 11 - INCOME TAXES AND TAX-RELATED ITEMS
At June 30, 2015, net unrecognized tax benefits were $22 million, compared to $14 million at December 31, 2014. The Corporation anticipates that it is reasonably possible that final settlement of federal and state tax issues will result in a decrease in net unrecognized tax benefits of $8 million within the next twelve months. Included in "accrued expense and other liabilities" on the consolidated balance sheets was a $3 million liability for tax-related interest and penalties at June 30, 2015 compared to $2 million at December 31, 2014.
Net deferred tax assets were $135 million at June 30, 2015, compared to $130 million at December 31, 2014. Deferred tax assets were evaluated for realization and it was determined that no valuation allowance was needed at both June 30, 2015 and December 31, 2014. This conclusion was based on sufficient taxable income in the carryback period and projected future reversals of existing taxable temporary differences to absorb the deferred tax assets.
In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service (IRS) may review and/or challenge specific interpretive tax positions taken by the Corporation with respect to those transactions. The Corporation believes that its tax returns were filed based upon applicable statutes, regulations and case law in effect at the time of the transactions. The IRS, an administrative authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law.
Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that current tax reserves are adequate, and the amount of any potential incremental liability arising is not expected to have a material adverse effect on the Corporation’s consolidated financial condition or results of operations. Probabilities and outcomes are reviewed as events unfold, and adjustments to the reserves are made when necessary.
NOTE 12 - CONTINGENT LIABILITIES
Legal Proceedings
As previously reported in the Corporation's Form 10-K for the year ended December 31, 2014 and Form 10-Q for the period ended March 31, 2015, Comerica Bank, a wholly owned subsidiary of the Corporation, was named in November 2011 as a third-party defendant in Butte Local Development v. Masters Group v. Comerica Bank (“the case”), for lender liability. The case was tried in January 2014, in the Montana Second District Judicial Court for Silver Bow County in Butte, Montana. On January 17, 2014, a jury awarded Masters $52 million against the Bank. On July 1, 2015, after an appeal filed by the Corporation, the Montana Supreme Court ("the court") reversed the judgment against the Corporation and remanded the case for a new trial with instructions that Michigan law should apply. The court also reversed punitive and consequential damages previously awarded by the jury. Masters subsequently petitioned the court for rehearing, asking the court to affirm the economic damages portion of the jury verdict (approximately $25 million). The Corporation believes it has meritorious defenses to the remaining claims in this case and intends to continue to defend itself vigorously.
The Corporation and certain of its subsidiaries are subject to various other pending or threatened legal proceedings arising out of the normal course of business or operations. The Corporation believes it has meritorious defenses to the claims asserted against it in its other currently outstanding legal proceedings and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interests of the Corporation and its shareholders. Settlement may result from the Corporation's determination that it may be more prudent financially to settle, rather than litigate, and should not be regarded as an admission of liability. On at least a quarterly basis, the Corporation assesses its potential liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. On a case-by-case basis, reserves are established for those legal claims for which it is probable that a loss will be incurred either as a result of a settlement or judgment, and the amount of such loss can be reasonably estimated. The actual costs of resolving these claims may be substantially higher or lower than the amounts reserved. Based on current knowledge, and after consultation with legal counsel, management believes that current reserves are adequate, and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on the Corporation’s consolidated financial condition,

consolidated results of operations or consolidated cash flows. Legal fees of $5 million were included in "other noninterest expenses" on the consolidated statements of income for both the three-month periods ended June 30, 2015 and 2014 and $10 million for both the six-month periods ended June 30, 2015 and 2014.
For matters where a loss is not probable, the Corporation has not established legal reserves. The Corporation believes the estimate of the aggregate range of reasonably possible losses, in excess of reserves established, for all legal proceedings in which it is involved is from zero to approximately $43 million at June 30, 2015. This estimated aggregate range of reasonably possible losses is based upon currently available information for those proceedings in which the Corporation is involved, taking into account the Corporation’s best estimate of such losses for those cases for which such estimate can be made. For certain cases, the Corporation does not believe that an estimate can currently be made. The Corporation’s estimate involves significant judgment, given the varying stages of the proceedings (including the fact that many are currently in preliminary stages), the existence in certain proceedings of multiple defendants (including the Corporation) whose share of liability has yet to be determined, the numerous yet-unresolved issues in many of the proceedings (including issues regarding class certification and the scope of many of the claims) and the attendant uncertainty of the various potential outcomes of such proceedings. Accordingly, the Corporation’s estimate will change from time to time, and actual losses may be more or less than the current estimate.
In the event of unexpected future developments, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to the Corporation's consolidated financial condition, consolidated results of operations or consolidated cash flows.
For information regarding income tax contingencies, refer to Note 11.
NOTE 13 - BUSINESS SEGMENT INFORMATION
The Corporation has strategically aligned its operations into three major business segments: the Business Bank, the Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. Business segment results are produced by the Corporation’s internal management accounting system. This system measures financial results based on the internal business unit structure of the Corporation. The performance of the business segments is not comparable with the Corporation's consolidated results and is not necessarily comparable with similar information for any other financial institution. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. The management accounting system assigns balance sheet and income statement items to each business segment using certain methodologies, which are regularly reviewed and refined. These methodologies may be modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product lines. For comparability purposes, amounts in all periods are based on business segments and methodologies in effect at June 30, 2015.
In the second quarter 2014, the Corporation enhanced the approach used to determine the standard reserve factors used in estimating the allowance for credit losses, which had the effect of capturing certain elements in the standard reserve component that had formerly been included in the qualitative assessment. The impact of the change was largely neutral to the total allowance for loan losses at June 30, 2014. However, because standard reserves are allocated to the segments at the loan level, while qualitative reserves are allocated at the portfolio level, the impact of the methodology change on the allowance of each segment reflected the characteristics of the individual loans within each segment's portfolio, causing segment reserves to increase or decrease accordingly. As a result, the current year provision for credit losses within each segment is not comparable to prior period amounts.
The following discussion provides information about the activities of each business segment. A discussion of the financial results and the factors impacting performance can be found in the section entitled "Business Segments" in the financial review.
The Business Bank meets the needs of middle market businesses, multinational corporations and governmental entities by offering various products and services, including commercial loans and lines of credit, deposits, cash management, capital market products, international trade finance, letters of credit, foreign exchange management services and loan syndication services.
The Retail Bank includes small business banking and personal financial services, consisting of consumer lending, consumer deposit gathering and mortgage loan origination. In addition to a full range of financial services provided to small business customers, this business segment offers a variety of consumer products, including deposit accounts, installment loans, credit cards, student loans, home equity lines of credit and residential mortgage loans.
Wealth Management offers products and services consisting of fiduciary services, private banking, retirement services, investment management and advisory services, investment banking and brokerage services. This business segment also offers the sale of annuity products, as well as life, disability and long-term care insurance products.

The Finance segment includes the Corporation’s securities portfolio and asset and liability management activities. This segment is responsible for managing the Corporation’s funding, liquidity and capital needs, performing interest sensitivity analysis and executing various strategies to manage the Corporation’s exposure to liquidity, interest rate risk and foreign exchange risk.
The Other category includes discontinued operations, the income and expense impact of equity and cash, tax benefits not assigned to specific business segments, charges of an unusual or infrequent nature that are not reflective of the normal operations of the business segments and miscellaneous other expenses of a corporate nature.
For further information on the methodologies which form the basis for these results refer to Note 22 to the consolidated financial statements in the Corporation's 2014 Annual Report.

Such statements reflect the view of the Corporation's management as of this date with respect to future events and are subject to risks and uncertainties. Should one or more of these risks materialize or should underlying beliefs or assumptions prove incorrect, the Corporation's actual results could differ materially from those discussed. Factors that could cause or contribute to such differences are changes in general economic, political or industry conditions; changes in monetary and fiscal policies, including changes in interest rates; changes in regulation or oversight; Comerica's ability to maintain adequate sources of funding and liquidity; the effects of more stringent capital or liquidity requirements; declines or other changes in the businesses or industries of Comerica's customers, including the energy industry; operational difficulties, failure of technology infrastructure or information security incidents; reliance on other companies to provide certain key components of business infrastructure; factors impacting noninterest expenses which are beyond Comerica's control; changes in the financial markets, including fluctuations in interest rates and their impact on deposit pricing; changes in Comerica's credit rating; unfavorable developments concerning credit quality; the interdependence of financial service companies; the implementation of Comerica's strategies and business initiatives; Comerica's ability to utilize technology to efficiently and effectively develop, market and deliver new products and services; competitive product and pricing pressures among financial institutions within Comerica's markets; changes in customer behavior; any future strategic acquisitions or divestitures; management's ability to maintain and expand customer relationships; management's ability to retain key officers and employees; the impact of legal and regulatory proceedings or determinations; the effectiveness of methods of reducing risk exposures; the effects of terrorist activities and other hostilities; the effects of catastrophic events including, but not limited to, hurricanes, tornadoes, earthquakes, fires, droughts and floods; changes in accounting standards and the critical nature of Comerica's accounting policies. The Corporation cautions that the foregoing list of factors is not exclusive. For discussion of factors that may cause actual results to differ from expectations, please refer to our filings with the Securities and Exchange Commission. In particular, please refer to “Item 1A. Risk Factors” beginning on page 12 of Comerica's Annual Report on Form 10-K for the year ended December 31, 2014. Forward-looking statements speak only as of the date they are made. The Corporation does not undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward-looking statements are made. For any forward-looking statements made in this report or in any documents, the Corporation claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

RESULTS OF OPERATIONS
Net income for the three months ended June 30, 2015 was $135 million, a decrease of $16 million from $151 million reported for the three months ended June 30, 2014. The decrease in net income primarily reflected a $36 million increase in the provision for credit losses and increases in revenue-generating noninterest expenses and technology-related contract labor expense, partially offset by a $33 million decrease in litigation-related expense as well as increases in net interest income and several fee-based noninterest income categories. Net income per diluted common share was $0.73 and $0.80 for the three months ended June 30, 2015 and 2014, respectively. Average diluted common shares were 182 million and 186 million for the three months ended June 30, 2015 and 2014, respectively.
Net income for the six months ended June 30, 2015 was $269 million, a decrease of $21 million from $290 million reported for the six months ended June 30, 2014. The decrease in net income was largely due to the same reasons as described in the quarterly discussion above. Net income per diluted common share was $1.46 and $1.54 for the six months ended June 30, 2015 and 2014, respectively. Average diluted common shares were 182 million and 186 million for the six months ended June 30, 2015 and 2014, respectively.
Full-Year 2015 Outlook Compared to Full-Year 2014
Management expectations for full-year 2015 compared to full-year 2014, assuming a continuation of the current economic and low-rate environment, are as follows:
Average full-year loan growth consistent with 2014, reflecting seasonal declines in Mortgage Banker Finance and National Dealer Services in the second half of the year, a continued decline in Energy, and a sustained focus on pricing and structure discipline.
Net interest income relatively stable, assuming no rise in interest rates, reflecting a decrease of about $30 million in purchase accounting accretion, to about $6 million, and the impact of a continuing low rate environment on asset yields, offset by earning asset growth.
Provision for credit losses higher, with third and fourth quarter net charge-offs each at levels similar to the second quarter. If energy prices remain low, continued negative migration is possible, which may be offset by lower exposure balances.
Noninterest income relatively stable, excluding the impact of a change in accounting presentation for a card program. Stable noninterest income reflects growth in fee income, particularly card fees and fiduciary income, mostly offset by a decline in warrant income and regulatory impacts on letter of credit and derivative income.
Noninterest expenses higher, excluding the impact of a change in accounting presentation for a card program, with continued focus on driving efficiencies for the long term. Expenses for the second half of 2015 are expected to be higher than the first half, reflecting three more days in the second half, the impact of merit increases, a ramp-up in the second half of technology and regulatory expenses, as well as higher pension, outside processing and occupancy expenses. Technology and regulatory expenses are expected to increase approximately $40 million in total compared to 2014.
Income tax expense to approximate 32 percent of pre-tax income.

For information about the change in accounting presentation for a card program, refer to Note 1 to the unaudited consolidated financial statements and under the "Noninterest Income" subheading later in this section of the financial review.

Net interest income was $421 million for the three months ended June 30, 2015, an increase of $5 million compared to $416 million for the three months ended June 30, 2014. The increase in net interest income resulted primarily from the benefit provided by an increase in average earning assets and a decrease in average medium- and long-term debt, partially offset by the impact of lower yields on loans and investment securities. Average earning assets increased $3.8 billion, or 6 percent, compared to $60.1 billion for the same period in 2014. The increase in average earning assets primarily reflected increases of $2.1 billion in average loans, $1.2 billion in average interest-bearing deposits with banks and $572 million in average investment securities. The net interest margin (FTE) for the three months ended June 30, 2015 decreased 13 basis points to 2.65 percent, from 2.78 percent for the comparable period in 2014, primarily from an increase in balances deposited with the Federal Reserve Bank (FRB) as well as lower yields on loans and investment securities. The decrease in loan yields primarily reflected a decrease in accretion on the acquired loan portfolio, shifts in the average loan portfolio mix and the impact of a competitive low-rate environment, partially offset by a benefit from the increase in 30-day LIBOR. Accretion of the purchase discount on the acquired loan portfolio increased the net interest margin by 1 basis point for the three months ended June 30, 2015, compared to 7 basis points for the same period in 2014. Average balances deposited with the FRB were $5.0 billion and $3.8 billion in the three months ended June 30, 2015 and 2014, respectively, and are included in "interest bearing deposits with banks" on the consolidated balance sheets.

Net interest income was $834 million for the six months ended June 30, 2015, an increase of $8 million compared to $826 million for the six months ended June 30, 2014. The increase in net interest income resulted primarily from the benefit provided by an increase in average earning assets and a decrease in average medium- and long-term debt, partially offset by the impact of lower yields on loans and investment securities. Average earning assets increased $3.7 billion, or 6 percent, to $63.7 billion for the six months ended June 30, 2015, compared to $60.0 billion for the same period in 2014. The increase in average earning assets primarily reflected increases of $2.6 billion in average loans, $599 million in average investment securities and $521 million in average interest-bearing deposits with banks. The net interest margin (FTE) for the six months ended June 30, 2015 decreased 13 basis points to 2.65 percent, from 2.78 percent for the comparable period in 2014, largely for the same reasons as discussed previously in the quarterly analysis. The decrease in loan yields reflected a decrease in accretion on the acquired loan portfolio, shifts in the average loan portfolio mix and the impact of a competitive low-rate environment, partially offset by a benefit from the increase in 30-day LIBOR. Accretion of the purchase discount on the acquired loan portfolio increased the net interest margin by 1 basis point for the six months ended June 30, 2015, compared to 7 basis points for the same period in 2014. Average balances deposited with the Federal Reserve Bank (FRB) were 5.1 billion and $4.6 billion in the six months ended June 30, 2015 and 2014, respectively, and are included in "interest bearing deposits with banks" on the consolidated balance sheets.

Provision for Credit Losses
The provision for credit losses was $47 million and $11 million for the three-month periods ended June 30, 2015 and 2014, respectively, and $61 million and $20 million for the six-month periods ended June 30, 2015 and 2014, respectively. The provision for credit losses includes both the provision for loan losses and the provision for credit losses on lending-related commitments.
The provision for loan losses is recorded to maintain the allowance for loan losses at the level deemed appropriate by the Corporation to cover probable credit losses inherent in the portfolio. The provision for loan losses was $35 million for the three months ended June 30, 2015, compared to $6 million for the three months ended June 30, 2014. The increase in the provision primarily reflected the impact of loan growth and increased reserves for energy and energy-related loans, as a result of an increase in criticized loans and the impact of continued volatility and sustained lower energy prices. In addition, Corporate Banking and, to a lesser extent, Technology and Life Sciences contributed to the increase in the provision, largely as a result of charge-offs and variability. These increases were partially offset by improvements in credit quality in the remainder of the portfolio. The provision for loan losses was $51 million for the six months ended June 30, 2015, an increase of $37 million compared to $14 million for the same period in the prior year, largely for the same reasons as the quarterly increase discussed above, with the exception of Technology and Life Sciences, which did not contribute to the year-to-date provision increase.
Net loan charge-offs in the three months ended June 30, 2015 increased $9 million to $18 million, or 0.15 percent of average total loans, compared to $9 million, or 0.08 percent, for the three months ended June 30, 2014. The increase in net loan charge-offs in the three months ended June 30, 2015, compared to the same period in 2014, primarily reflected increases in Corporate Banking and Technology and Life Sciences, partially offset by a decrease in Commercial Real Estate.
Net loan charge-offs in the six months ended June 30, 2015 increased $5 million to $26 million, or 0.11 percent of average total loans, compared to $21 million, or 0.09 percent, for the six months ended June 30, 2014. The increase in net loan charge-offs

in the six months ended June 30, 2015, compared to the same period in 2014, primarily reflected increases in general Middle Market and Corporate Banking, partially offset by decreases in most other business lines, with the largest decreases in Commercial Real Estate as well as Technology and Life Sciences.
The provision for credit losses on lending-related commitments is recorded to maintain the allowance for credit losses on lending-related commitments at the level deemed appropriate by the Corporation to cover probable credit losses inherent in lending-related commitments. The provision for credit losses on lending-related commitments was $12 million in the three months ended June 30, 2015, compared to $5 million in the three months ended June 30, 2014, and $10 million for the six months ended June 30, 2015 compared to $6 million for the same period in 2014. The $7 million increase in the provision for credit losses on lending-related commitments in the three months ended June 30, 2015 compared to the same period in 2014, as well as the $4 million increase in the provision for credit losses on lending-related commitments in the six months ended June 30, 2015 compared to the same period in 2014, primarily reflected additional reserves for energy and energy-related commitments. Lending-related commitment charge-offs were $1 million for the three- and six-month periods ended June 30, 2015 and insignificant for the same periods in 2014.
An analysis of the allowance for credit losses and nonperforming assets is presented under the "Credit Risk" subheading in the "Risk Management" section of this financial review.

(a)
Effective January 1, 2015, contractual changes to a card program resulted in a change to the accounting presentation of the related revenues and expenses. The effect of this change was increases of $44 million and $88 million to card fees in the three- and six-month periods ended June 30, 2015, respectively.
(b)
The table below provides further details on certain categories included in other noninterest income.
Noninterest income was $261 million for the three months ended June 30, 2015, an increase of $41 million compared to $220 million for the same period in 2014. Excluding the $44 million impact of the change in accounting presentation on card fees as described in footnote (a) to the above table, noninterest income decreased $3 million, primarily reflecting increases in card fees, fiduciary income and service charges on deposit accounts, which were more than offset by declines in foreign exchange income and several non-fee categories. Card fees increased $6 million, primarily driven by a change to the Corporation's strategy for providing merchant payment processing services. The Corporation concluded its participation in a joint venture that provided merchant payment processing services in the second quarter 2015. Income from the joint venture was recorded in other noninterest income using the equity method. The Corporation now directly enters into agreements with its merchants and uses a third party to process the transactions. Pursuant to the agreements with the merchants and the arrangement with the third-party vendor, merchant payment processing income is recognized in card fees, and related processing expense is recognized in outside processing fees in noninterest expenses. For further discussion about the impact of using a third party to process merchant transactions on outside processing fees, refer to the "Noninterest Expenses" subheading below. Fiduciary income increased $3 million and service charges on deposit accounts increased $2 million. These increases were more than offset by decreases of $3 million each in foreign exchange income and income from principal investing and warrants, along with small decreases in several other non-fee categories.
Noninterest income was $516 million for the six months ended June 30, 2015, an increase of $88 million compared to $428 million for the same period in 2014. Excluding the $88 million impact of the above-described accounting presentation change, noninterest income was unchanged. Within noninterest income, fiduciary income and card fees each increased $6 million, commercial lending fees increased $4 million and service charges on deposit accounts increased $3 million. Offsetting the increases in noninterest income were decreases of $5 million in income from principal investing and warrants, $3 million each in net securities gains and letter of credit fee income, and $2 million in foreign exchange income, as well as small decreases in several other non-fee categories.

(a)
Effective January 1, 2015, contractual changes to a card program resulted in a change to the accounting presentation of the related revenues and expenses. The effect of this change was increases of $44 million and $88 million to outside processing fee expense in the three- and six-month periods ended June 30, 2015, respectively.
Noninterest expenses were $436 million for the three months ended June 30, 2015, an increase of $32 million compared to $404 million for the three months ended June 30, 2014. Excluding the $44 million impact of the change in accounting presentation on outside processing fees as described in footnote (a) to the above table, noninterest expenses decreased $12 million in the three months ended June 30, 2015, compared to the same period in the prior year, largely reflecting a $33 million reduction in litigation-related expenses, partially offset by higher outside processing expenses related to revenue generating activities and an increase in salaries and benefits expense. See to Note 12 to the consolidated financial statements for information related to litigation expense. Salaries and benefits expense increased $11 million, primarily reflecting an increase in technology-related contract labor expense and the impact of merit increases. Excluding the impact of the accounting presentation change described above, outside processing fee expense increased $11 million, largely due to third-party processing expenses associated with merchant payment processing services, as discussed under the "Noninterest Income" subheading above, including up-front costs incurred for converting customers to the new vendor providing the services, as well as smaller increases in other outside processing expenses related to revenue-generating activities.
Noninterest expenses were $895 million for the six months ended June 30, 2015, an increase of $85 million compared to $810 million for the six months ended June 30, 2014. Excluding the $88 million impact of the above-described accounting presentation change, noninterest expenses decreased $3 million in the six months ended June 30, 2015, compared to the same period in the prior year, for substantially the same reasons as described in the quarterly discussion above.
STRATEGIC LINES OF BUSINESS
The Corporation's management accounting system assigns balance sheet and income statement items to each segment using certain methodologies, which are regularly reviewed and refined. These methodologies may be modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product lines. Note 22 to the consolidated financial statements in the Corporation's 2014 Annual Report describes the Corporation's segment reporting methodology.

Table of Contents

In the second quarter 2014, the Corporation enhanced the approach used to determine the standard reserve factors used in estimating the allowance for credit losses, which had the effect of capturing certain elements in the standard reserve component that had formerly been included in the qualitative assessment. The impact of the change was largely neutral to the total allowance for loan losses at June 30, 2014. However, because standard reserves are allocated to the segments at the loan level, while qualitative reserves are allocated at the portfolio level, the impact of the methodology change on the allowance of each segment reflected the characteristics of the individual loans within each segment's portfolio, causing segment reserves to increase or decrease accordingly. As a result, the current year provision for credit losses within each segment is not comparable to prior year amounts.
Business Segments
The Corporation's operations are strategically aligned into three major business segments: the Business Bank, the Retail Bank and Wealth Management. These business segments are differentiated based upon the products and services provided. In addition to the three major business segments, Finance is also reported as a segment. The Other category includes items not directly associated with these business segments or the Finance segment. The performance of the business segments is not comparable with the Corporation's consolidated results and is not necessarily comparable with similar information for any other financial institution. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. Note 13 to the consolidated financial statements describes the business activities of each business segment and presents financial results of these business segments for the three- and six-month periods ended June 30, 2015 and 2014.
The following table presents net income (loss) by business segment.

The Business Bank's net income of $371 million for the six months ended June 30, 2015 decreased $24 million compared to the six months ended June 30, 2014. Net interest income (FTE) of $744 million for the six months ended June 30, 2015 was unchanged compared to the same period in the prior year, as the benefit from a $2.3 billion increase in average loans and the funds transfer pricing (FTP) benefit provided by a $3.0 billion increase in average deposits were offset by a decrease in accretion of the purchase discount on the acquired loan portfolio, lower loan yields and a lower FTP crediting rate.The provision for credit losses increased $34 million to $86 million for the six months ended June 30, 2015, compared to the same period in the prior year. The increase in the provision primarily reflected the impact of loan growth and increased reserves for loans related to energy, as a result of an increase in criticized loans and the impact of continued volatility and sustained lower energy prices. In addition, Corporate Banking contributed to the increase in the provision. These increases were partially offset by improvements in credit quality in Commercial Real Estate. Net loan charge-offs of $31 million increased $11 million in the six months ended June 30, 2015, compared to the same period in the prior year, primarily reflecting increases in general Middle Market and Corporate Banking, partially offset by decreases in Commercial Real Estate and Technology and Life Sciences. Excluding the impact of the change in accounting presentation for a card program, noninterest income for the six months ended June 30, 2015 increased $3 million from the comparable period in the prior year, primarily reflecting increases of $5 million each in card fees and commercial lending fees, partially offset by a $4 million decrease in warrant income. Excluding the impact of the change in accounting presentation for a card program, noninterest expenses for the six months ended June 30, 2015 decreased $1 million compared to the same period in the prior year. The decrease primarily reflected a $31 million decrease in litigation-related expense, mostly offset by a $15 million increase in corporate overhead; a $10 million increase in outside processing expenses, largely due to the third-party processing expenses associated with merchant payment processing services resulting from a change to the Corporation's strategy for providing merchant services; and a $5 million increase in salaries and benefits expense, primarily reflecting the impact of merit increases.
Net income for the Retail Bank of $35 million for the six months ended June 30, 2015 increased $9 million, compared to $26 million for the six months ended June 30, 2014. Net interest income (FTE) of $307 million increased $6 million in the six months ended June 30, 2015, primarily due to the benefit provided by a $177 million increase in average loans, the FTP benefit provided by an $818 million increase in average deposits and lower deposit rates, partially offset by a lower FTP crediting rate and a decrease in accretion of the purchase discount on the acquired loan portfolio. The provision for credit losses was a benefit of $16 million for the six months ended June 30, 2015, a decrease of $11 million from the comparable period in the prior year,

reflecting decreases in the consumer loan portfolio and Small Business. Net loan charge-offs were $2 million for the six months ended June 30, 2015 compared to $6 million in the same period for the prior year. Noninterest income of $88 million for the six months ended June 30, 2015 increased $6 million compared to the comparable period in the prior year, due to small increases in several fee categories. Noninterest expenses of $357 million for the six months ended June 30, 2015 increased $9 million from the comparable period in the prior year, primarily due to an increase of $4 million in salaries and benefits expense, primarily reflecting the impact of merit increases, and an increase of $5 million in outside processing expenses related to revenue-generating activities.
Wealth Management's net income of $42 million for the six months ended June 30, 2015 decreased $7 million, compared to $49 million for the six months ended June 30, 2014. Net interest income (FTE) of $88 million for the six months ended June 30, 2015 decreased $1 million compared to the same period in the prior year, primarily reflecting a decrease in net FTP credits and lower loan yields, partially offset by the benefit from a $111 million increase in average loans and the FTP benefit provided by a $429 million increase in average deposits. The provision for credit losses was a benefit of $10 million for the six months ended June 30, 2015, compared to a benefit of $18 million for the same period in the prior year. Net loan recoveries were $7 million for the six months ended June 30, 2015, compared to net recoveries of $5 million for the comparable prior year period. Noninterest income of $118 million decreased $4 million, primarily reflecting a $3 million decrease from securities losses of $2 million for the six months ended June 30, 2015 compared to a $1 million gain for the same period in 2014. Noninterest expenses of $151 million for the six months ended June 30, 2015 decreased $1 million from the comparable period in the prior year, primarily due to a $4 million decrease in litigation-related expenses, partially offset by small increases in several noninterest expense categories.
The net loss in the Finance segment was $179 million for the six months ended June 30, 2015, compared to a net loss of $183 million for the six months ended June 30, 2014. Net interest expense (FTE) of $308 million for the six months ended June 30, 2015 decreased $10 million, compared to the six months ended June 30, 2014, primarily reflecting a decrease in net FTP expense as a result of lower rates paid to the business segments under the Corporation's internal FTP methodology.
Market Segments
Market segment results are provided for the Corporation's three largest geographic markets: Michigan, California and Texas. In addition to the three largest geographic markets, Other Markets is also reported as a market segment. The Finance & Other category includes the Finance segment and the Other category as previously described in the "Business Segments" section of this financial review. Note 13 to these consolidated financial statements presents a description of each of these market segments as well as the financial results for the three- and six-month periods ended June 30, 2015 and 2014.

The Michigan market's net income of $172 million for the six months ended June 30, 2015 increased $30 million, compared to $142 million for the six months ended June 30, 2014. Net interest income (FTE) of $357 million for the six months ended June 30, 2015 decreased $7 million from the comparable period in the prior year, primarily due to lower loan yields, the impact of a $221 million decrease in average loans and a lower FTP crediting rate, partially offset by the FTP benefit provided by a $1.0 billion increase in average deposits and lower deposit rates. The provision for credit losses was a benefit of $21 million for the six months ended June 30, 2015, compared to a benefit of $5 million for the comparable period in the prior year. Net loan charge-offs were $1 million for the six months ended June 30, 2015, compared to $10 million for the comparable period in the prior year, primarily reflecting decreases in Commercial Real Estate and Small Business, partially offset by an increase in general Middle Market. Noninterest income of $166 million for the six months ended June 30, 2015 decreased $7 million from the comparable period in the prior year, reflecting small decreases in several noninterest income categories. Noninterest expenses of $283 million for the six months ended June 30, 2015 decreased $37 million from the comparable period in the prior year, primarily reflecting a $32 million decrease in litigation-related expense and small decreases in several other noninterest expense categories, partially offset by a $6 million increase in outside processing expense, in part due to the third-party processing expenses associated with merchant payment processing services resulting from a change to the Corporation's strategy.

Noninterest income of $67 million for the six months ended June 30, 2015 decreased $2 million compared to the comparable period in the prior year, primarily due to small decreases in several noninterest income categories.

Net income in Other Markets of $86 million for the six months ended June 30, 2015 decreased $30 million from the six months ended June 30, 2014. Net interest income (FTE) of $165 million for the six months ended June 30, 2015 increased $17 million from the comparable period in the prior year, primarily due to the benefit provided by a $904 million increase in average loans and the FTP benefit provided by a $1.1 billion increase in average deposits, partially offset by the impact of a lower FTP crediting rate. The provision for credit losses of $16 million increased $36 million in the six months ended June 30, 2015, compared to a benefit of $20 million for the same period in the prior year, primarily reflecting increases in Corporate Banking and general Middle Market. Net loan charge-offs were $11 million for the six months ended June 30, 2015, compared to net recoveries of $12 million for the comparable period in the prior year, primarily reflecting increases in Corporate Banking, Technology and Life Sciences, and general Middle Market. Excluding the impact of the change in accounting presentation for a card program, noninterest income for the six months ended June 30, 2015 increased $13 million from the comparable period in the prior year, primarily reflecting increases of $3 million in fiduciary income, $2 million in customer derivative income and small increases in several other noninterest income categories, partially offset by a $3 million decrease from securities losses of $2 million for the six months ended June 30, 2015 compared to a $1 million gain for the same period in 2014. Excluding the impact of the change in accounting presentation for a card program, noninterest expenses for the six months ended June 30, 2015 increased $32 million compared to the same period in the prior year, primarily due to an increase of $8 million in outside processing expenses in part due to the third-party processing expenses associated with merchant payment processing services resulting from a change to the Corporation's strategy, an $8 million increase in corporate overhead expense and small increases in several categories of noninterest expense.
The net loss for the Finance & Other category of $179 million in the six months ended June 30, 2015 decreased $1 million compared to the six months ended June 30, 2014. For further information, refer to the Finance segment discussion under the "Business Segments" subheading above.

FINANCIAL CONDITION
Total assets were $69.9 billion at June 30, 2015, an increase of $759 million from $69.2 billion at December 31, 2014, primarily reflecting increases of $1.1 billion in total loans, $168 million in investment securities and $122 million in cash and due from banks, partially offset by decreases of $456 million in accrued income and other assets and $228 million in interest-bearing deposits with banks. On an average basis, total assets decreased $344 million to $69.0 billion in the second quarter 2015, compared to $69.3 billion in the fourth quarter 2014, resulting primarily from a decrease of $2.5 billion in average interest-bearing deposits with banks, partially offset by increases of $1.5 billion in average loans and $571 million in average investment securities.

The Corporation periodically conducts stress tests to evaluate potential impacts to the Corporation's forecasted financial condition under various economic scenarios and business conditions. These stress tests are a normal part of the Corporation's overall risk management and capital planning process and are part of the forecasting process used by the Corporation to conduct the enterprise-wide stress test that was part of the Federal Reserve's Comprehensive Capital Analysis and Review (CCAR). For additional information about risk management processes, refer to the "Risk Management" sections of this financial review and the Corporations 2014 Annual Report.

The Federal Reserve completed its 2015 CCAR review in March 2015 and did not object to the Corporation's capital plan and capital distributions contemplated in the plan. The plan provides for up to $393 million in equity repurchases for the five-quarter period ending June 30, 2016. In the second quarter 2015, the Corporation's equity repurchases totaled $59 million, including $49 million of share repurchases and $10 million of warrant repurchases. The pace of equity repurchases is expected to be in line with the Corporation's performance and a rise in interest rates. The following table summarizes the Corporation's repurchase activity during the six months ended June 30, 2015.

Includes approximately 172,000 shares purchased pursuant to deferred compensation plans and shares purchased from employees to pay for taxes related to restricted stock vesting under the terms of an employee share-based compensation plan during the six months ended June 30, 2015. These transactions are not considered part of the Corporation's repurchase program.
(c)
The Corporation repurchased 500,000 warrants under the repurchase program during the six months ended June 30, 2015. Shares withheld in connection with the exercise of warrants are not included in the total number of shares or warrants purchased in the above table. Upon exercise of a warrant, the number of shares with a value equal to the aggregate exercise price is withheld from an exercising warrant holder as payment (known as a "net exercise provision"). During the six months ended June 30, 2015, the Corporation withheld the equivalent of approximately 1,261,000 shares to cover an aggregate of $64.8 million in exercise price and issued approximately 934,000 shares to the exercising warrant holders.
(d)
Includes April 28, 2015 equity repurchase authorization for up to an additional 10.6 million shares and share-equivalents.
On April 28, 2015, the Board of Directors of the Corporation (the Board) approved a 1-cent increase in the quarterly dividend to $0.21 per share. The Board also authorized the repurchase of up to an additional 10.0 million shares of Comerica Incorporated outstanding common stock, in addition to the 2.1 million shares remaining at March 31, 2015 under the Board's prior authorizations for the share repurchase program initially approved in November 2010. Including the April 28, 2015 authorization, a total of 40.3 million shares has been authorized for repurchase under the share repurchase program since its inception in 2010. On April 28, 2015, the Board also authorized the repurchase of up to an additional 2.6 million warrants, in addition to the 10.6 million warrants remaining at March 31, 2015 under an authorization initially approved in November 2010. There is no expiration date for the Corporation's equity repurchase program.
In July 2013, U.S. banking regulators issued a final rule for the U.S. adoption of the Basel III regulatory capital framework (Basel III). Basel III includes a more stringent definition of capital and introduces a new common equity Tier 1 (CET1) capital requirement; sets forth two comprehensive methodologies for calculating risk-weighted assets (RWA), a standardized approach and an advanced approach; introduces two new capital buffers, a conservation buffer and a countercyclical buffer (applicable to advanced approaches entities); establishes a new supplemental leverage ratio (applicable to advanced approaches entities); and sets out minimum capital ratios and overall capital adequacy standards. As a banking organization subject to the standardized approach, Basel III became effective for the Corporation on January 1, 2015. Certain deductions and adjustments to regulatory capital phase in starting January 1, 2015 and will be fully implemented on January 1, 2018. The capital conservation buffer phases in beginning January 1, 2016 and will be fully implemented on January 1, 2019.
Under Basel III, CET1 capital predominantly includes common shareholders’ equity, less certain deductions for goodwill, intangible assets and deferred tax assets that arise from net operating losses and tax credit carry-forwards. Additionally, the Corporation has elected to permanently exclude capital in accumulated other comprehensive income (AOCI) related to debt and equity securities classified as available-for-sale as well as for defined benefit postretirement plans from CET1, an option available to standardized approach entities under Basel III. Tier 1 capital incrementally includes noncumulative perpetual preferred stock. Tier 2 capital includes Tier 1 capital as well as subordinated debt qualifying as Tier 2 and qualifying allowance for credit losses. Certain deductions and adjustments to CET1 capital, Tier 1 capital and Tier 2 capital are subject to phase-in through December 31, 2017.
Comerica computes RWA using the standardized approach. Under the standardized approach, RWA is generally based on supervisory risk-weightings which vary by counterparty type and asset class. Under the Basel III standardized approach, capital is required for credit risk RWA, to cover the risk of unexpected losses due to failure of a customer or counterparty to meet its

financial obligations in accordance with contractual terms; and if trading assets and liabilities exceed certain thresholds, capital is also required for market risk RWA, to cover the risk of losses due to adverse market movements or from position-specific factors.

RISK MANAGEMENT
The following updated information should be read in conjunction with the "Risk Management" section on pages F-21 through F-36 in the Corporation's 2014 Annual Report.
Credit Risk
Allowance for Credit Losses
The allowance for credit losses includes both the allowance for loan losses and the allowance for credit losses on lending-related commitments. The allowance for loan losses represents management's assessment of probable, estimable losses inherent in the Corporation's loan portfolio. The allowance for credit losses on lending-related commitments, included in "accrued expenses and other liabilities" on the consolidated balance sheets, provides for probable losses inherent in lending-related commitments, including unused commitments to extend credit and standby letters of credit.
While U.S. Gross Domestic Product (GDP) was relatively flat in the first quarter of 2015, it has shown some positive trends in the second quarter of 2015. Job growth and employment figures continue to slowly improve while manufacturing output is higher and inflation remains low. The Federal Reserve continues to set expectations for a near-term movement towards interest rate increases and monetary policy normalization. At the same time, lower energy prices have persisted and geopolitical tensions remain.
While the overall credit quality of the loan portfolio remained strong in the second quarter of 2015, reserves increased, primarily reflecting an increase in criticized energy and energy-related exposure, as well as uncertainty due to continued volatility and the impact of sustained lower oil and gas prices.
The allowance for loan losses was $618 million at June 30, 2015, compared to $594 million at December 31, 2014, an increase of $24 million, or 4 percent. The increase in the allowance primarily reflected increased reserves for loans related to energy and, to a lesser extent, Technology and Life Sciences, partially offset by credit quality improvements in the remainder of the portfolio.
Energy and energy-related loans at June 30, 2015 included approximately $3.3 billion of outstanding loans in the Energy business line as well as approximately $725 million of loans in other lines of business to companies that have a sizable portion of

52

Table of Contents

their revenue related to energy or could be otherwise disproportionately negatively impacted by prolonged lower oil and gas prices ("energy-related"). The Corporation generally reviews commitments to energy exploration and production (EP) customers semi-annually, in conjunction with scheduled borrowing base re-determinations. Internal risk ratings for all loans are reviewed at least annually, or more frequently upon the occurrence of a circumstance that affects the credit risk of the loan. During the six months ended June 30, 2015, approximately 85 percent of the internal risk ratings for borrowers in the Energy business line were reviewed, including approximately 95 percent of EP customers, 70 percent of energy services customers and 55 percent of midstream customers. The reviews resulted in some internal risk rating downgrades, which were incorporated into the quantitative component of the allowance. More than 90 percent of the loans in the Energy business line are Shared National Credits (SNC), and the above results include the results of the SNC exam completed in the second quarter 2015. In addition, the Corporation continued to incorporate a qualitative reserve component for energy and energy-related loans due to the uncertainty associated with continued volatility and the impact of sustained lower oil and gas prices. Refer to the "Energy Lending" subheading later in this section for further discussion of the Corporation's portfolio of energy and energy-related loans.
The allowance for credit losses on lending-related commitments includes specific allowances, based on individual evaluations of certain letters of credit in a manner consistent with business loans, and allowances based on the pool of the remaining letters of credit and all unused commitments to extend credit within each internal risk rating.
The allowance for credit losses on lending-related commitments was $50 million at June 30, 2015 compared to $41 million at December 31, 2014. The $9 million increase in the allowance for credit losses on lending-related commitments primarily reflected the impact of downgrades of energy and energy-related unfunded commitments and issued letters of credit.
For additional information regarding the allowance for credit losses, refer to page F-37 in the "Critical Accounting Policies" section and pages F-54 through F-55 in Note 1 to the consolidated financial statements of the Corporation's 2014 Annual Report.
Nonperforming Assets
Nonperforming assets include loans on nonaccrual status, troubled debt restructured loans (TDRs) which have been renegotiated to less than the original contractual rates (reduced-rate loans) and foreclosed property. TDRs include performing and nonperforming loans. Nonperforming TDRs are either on nonaccrual or reduced-rate status. Nonperforming assets do not include purchased credit impaired (PCI) loans.

The Corporation limits risk inherent in its commercial real estate lending activities by limiting exposure to those borrowers directly involved in the commercial real estate markets and adhering to conservative policies on loan-to-value ratios for such loans. Commercial real estate loans, consisting of real estate construction and commercial mortgage loans, totaled $10.5 billion at June 30, 2015, of which $3.4 billion, or 33 percent, were to borrowers in the Commercial Real Estate business line, which includes loans to real estate developers. The remaining $7.1 billion, or 67 percent, of commercial real estate loans in other business lines consisted primarily of owner-occupied commercial mortgages, which bear credit characteristics similar to non-commercial real estate business loans. In the Texas market, commercial real estate loans totaled $2.5 billion at June 30, 2015, of which $1.3 billion were to borrowers in the Commercial Real Estate business line. The remaining $1.2 billion consisted primarily of owner-occupied commercial mortgages. Loans in the Commercial Real Estate business line secured by properties located in Texas totaled $957 million at June 30, 2015, primarily including $525 million for multifamily properties, $130 million for retail properties and $101 million for commercial properties.
The real estate construction loan portfolio primarily contains loans made to long-time customers with satisfactory completion experience. Credit quality in the real estate construction loan portfolio was strong, with $1 million on nonaccrual status at June 30, 2015 compared to $2 million at December 31, 2014 and no real estate construction loan charge-offs in either of the six-month periods ended June 30, 2015 and 2014.
Loans in the commercial mortgage portfolio generally mature within three to five years. Of the $1.9 billion and $1.8 billion of commercial mortgage loans in the Commercial Real Estate business line outstanding at June 30, 2015 and December 31, 2014, respectively, $18 million and $22 million were on nonaccrual status at June 30, 2015 and December 31, 2014, respectively. Commercial mortgage loan net recoveries in the Commercial Real Estate business line were $3 million for the six months ended June 30, 2015, compared to net charge-offs of $5 million for the six months ended June 30, 2014. In other business lines, $59 million and $73 million of commercial mortgage loans were on nonaccrual status at June 30, 2015 and December 31, 2014, respectively. Commercial mortgage loan net recoveries in other business lines were $3 million for the six months ended June 30, 2015, compared to net charge-offs of $2 million for the six months ended June 30, 2014.

Residential real estate loans consist of traditional residential mortgages and home equity loans and lines of credit. Residential mortgages totaled $1.9 billion at June 30, 2015, and were primarily larger, variable-rate mortgages originated and retained for certain private banking relationship customers. Of the $1.9 billion of residential mortgage loans outstanding, $35 million were on nonaccrual status at June 30, 2015. The home equity portfolio totaled $1.7 billion at June 30, 2015, of which $1.6 billion was outstanding under primarily variable-rate, interest-only home equity lines of credit and $66 million were closed-end

home equity loans. Of the $1.7 billion of home equity loans outstanding, $29 million were on nonaccrual status at June 30, 2015. A majority of the home equity portfolio was secured by junior liens at June 30, 2015. The residential real estate portfolio is principally located within the Corporation's primary geographic markets. Substantially all residential real estate loans past due 90 days or more are placed on nonaccrual status, and substantially all junior lien home equity loans that are current or less than 90 days past due are placed on nonaccrual status if full collection of the senior position is in doubt. At no later than 180 days past due, such loans are charged off to current appraised values less costs to sell.
Energy Lending
The Corporation has a portfolio of energy and energy-related loans that are included primarily in "commercial loans" in the consolidated balance sheets. The Corporation's energy lending team has over 30 years of experience, with a focus on larger middle market companies. Loans in the Energy business line (approximately 200 relationships) were $3.3 billion, or approximately 7 percent of total loans, at both June 30, 2015 and December 31, 2014, and total exposure, including unused commitments to extend credit and letters of credit, was $6.6 billion and $7.1 billion at June 30, 2015 and December 31, 2014, respectively. More than 90 percent of the loans in the Energy business line are Shared National Credits (SNC), reflecting the Corporation's focus on larger middle market companies that have financing needs that generally exceed internal individual borrower credit risk limits. The Corporation seeks to develop full relationships with SNC borrowers. SNCs are facilities greater than $20 million shared by three or more federally supervised institutions. In addition to energy loans in the Energy business line, the Corporation is monitoring a portfolio of approximately 165 relationships with approximately $725 million outstanding and total exposure of about $1.5 billion at June 30, 2015 of energy-related loans to companies primarily in general Middle Market, Corporate Banking, Small Business, and Technology and Life Sciences.

EP generally includes such activities as searching for potential oil and gas fields, drilling exploratory wells and operating active wells. The midstream sector is generally involved in the transportation, storage and marketing of crude and/or refined energy products. The Corporation's energy services customers provide services primarily to the EP sector. As of June 30, 2015, a majority of the Corporation’s EP customers had at least 50 percent of their oil and/or gas production hedged up to the end of 2015. Approximately 95 percent of the amount of loans outstanding in the Energy business line had varying levels and types of collateral at June 30, 2015, including oil and gas reserves and pipelines, equipment, accounts receivable, inventory and other assets, or some combination thereof. Commitments to EP borrowers are generally subject to semi-annual borrowing base re-determinations based on a variety of factors including updated pricing (reflecting market and competitive conditions), energy reserve levels and the impact of hedging. As of the end of June 2015, about 95 percent of semi-annual borrowing base re-determinations for EP borrowers in the Energy line of business were complete, resulting in internal risk rating downgrades for about one-third of those reviewed. The Corporation's allowance methodology carefully considers the various risk elements within its loan portfolio. The allowance for loan losses at June 30, 2015 appropriately considered the changing dynamics in energy and energy-related loans described above, which has resulted in increases in the qualitative and quantitative reserve components for this portfolio for the past three quarterly periods.
Refer to the “Allowance for Credit Losses” subheading earlier in this section for a discussion of changes in the allowance for loan losses as a result of the above-described events.
Automotive Lending
Substantially all dealer loans are in the National Dealer Services business line. Loans in the National Dealer Services business line include floor plan financing and other loans to automotive dealerships. Floor plan loans, included in “commercial loans” in the consolidated balance sheets, totaled $3.8 billion at June 30, 2015, an increase of $50 million compared to December 31,

2014. At both June 30, 2015 and December 31, 2014, other loans to automotive dealers in the National Dealer Services business line totaled $2.4 billion, including $1.6 billion of owner-occupied commercial real estate mortgage loans. Automotive lending also includes loans to borrowers involved with automotive production, primarily Tier 1 and Tier 2 suppliers. Loans to borrowers involved with automotive production totaled approximately $1.4 billion and $1.2 billion at June 30, 2015 and December 31, 2014, respectively.
International Exposure
International assets are subject to general risks inherent in the conduct of business in foreign countries, including economic uncertainties and each foreign government's regulations. Risk management practices minimize the risk inherent in international lending arrangements. These practices include structuring bilateral agreements or participating in bank facilities, which secure repayment from sources external to the borrower's country. Accordingly, such international outstandings are excluded from the cross-border risk of that country.
The Corporation does not hold any sovereign exposure to Europe. The Corporation's international strategy as it pertains to Europe is to focus on European companies doing business in North America, with an emphasis on the Corporation's primary geographic markets. The following table summarizes cross-border exposure to entities domiciled in European countries.

For further discussion of credit risk, see the "Credit Risk" section of pages F-21 through F-29 in the Corporation's 2014 Annual Report.
Market and Liquidity Risk
Market risk represents the risk of loss due to adverse movements in market rates or prices, including interest rates, foreign exchange rates, and commodity and equity prices. Liquidity risk represents the failure to meet financial obligations coming due resulting from an inability to liquidate assets or obtain adequate funding, and the inability to easily unwind or offset specific exposures without significant changes in pricing, due to inadequate market depth or market disruptions.
The Asset and Liability Policy Committee (ALCO) of the Corporation establishes and monitors compliance with the policies and risk limits pertaining to market and liquidity risk management activities. ALCO meets regularly to discuss and review market and liquidity risk management strategies, and consists of executive and senior management from various areas of the Corporation, including treasury, finance, economics, lending, deposit gathering and risk management. The Treasury Department mitigates market and liquidity risk through the actions it takes to manage the Corporation's market, liquidity and capital positions under the direction of ALCO.
Market Risk Analytics, of the Office of Enterprise Risk, supports ALCO in measuring, monitoring and managing interest rate and liquidity risks and coordinating all other market risks. Key activities encompass: (i) providing information and analysis of the Corporation's balance sheet structure and measurement of interest rate, liquidity and all other market risks; (ii) monitoring and reporting of the Corporation's positions relative to established policy limits and guidelines; (iii) developing and presenting analyses and strategies to adjust risk positions; (iv) reviewing and presenting policies and authorizations for approval; (v) monitoring of industry trends and analytical tools to be used in the management of interest rate, liquidity and all other market risks; and (vi) developing and monitoring the interest rate risk economic capital estimate.
Interest Rate Risk
Net interest income is the primary source of revenue for the Corporation. Interest rate risk arises in the normal course of business due to differences in the repricing and cash flow characteristics of assets and liabilities, primarily through the Corporation's core business activities of extending loans and acquiring deposits. The Corporation's balance sheet is predominantly characterized by floating-rate loans funded by a combination of core deposits and wholesale borrowings. Approximately 85 percent of the Corporation's loans were floating at June 30, 2015, of which approximately 75 percent were based on LIBOR and 25 percent were based on Prime. This creates sensitivity to interest rate movements due to the imbalance between the floating-rate loan portfolio and the more slowly repricing deposit products. In addition, growth and/or contraction in the Corporation's loans and deposits may lead to changes in sensitivity to interest rate movements in the absence of mitigating actions. Examples of such actions are

59

Table of Contents

purchasing investment securities, primarily fixed-rate, which provide liquidity to the balance sheet and act to mitigate the inherent interest sensitivity, and hedging the sensitivity with interest rate swaps. The Corporation actively manages its exposure to interest rate risk, with the principal objective of optimizing net interest income and the economic value of equity while operating within acceptable limits established for interest rate risk and maintaining adequate levels of funding and liquidity.
Since no single measurement system satisfies all management objectives, a combination of techniques is used to manage interest rate risk. These techniques examine the impact of interest rate risk on net interest income and the economic value of equity under a variety of alternative scenarios, including changes in the level, slope and shape of the yield curve, utilizing multiple simulation analyses. Simulation analyses produce only estimates of net interest income, as the assumptions used are inherently uncertain. Actual results may differ from simulated results due to many factors, including, but not limited to, the timing, magnitude and frequency of changes in interest rates, market conditions, regulatory impacts and management strategies.
Sensitivity of Net Interest Income to Changes in Interest Rates
The analysis of the impact of changes in interest rates on net interest income under various interest rate scenarios is management's principal risk management technique. Management models a base case net interest income under an unchanged interest rate environment and what is believed to be the most likely balance sheet structure. Existing derivative instruments entered into for risk management purposes are included in the analysis, but no additional hedging is currently forecasted. These derivative instruments currently comprise interest rate swaps that convert fixed-rate long-term debt to variable rates. This base case net interest income is then compared against interest rate scenarios in which rates rise or decline in a linear, non-parallel fashion from the base case over 12 months. In the scenarios presented, short-term interest rates increase 200 basis points, resulting in an average increase in short-term interest rates of 100 basis points over the period (+200 scenario). Due to the current low level of interest rates, the analysis reflects a declining interest rate scenario of a 25 basis point drop in short-term interest rates, to zero percent.
Each scenario includes assumptions such as loan growth, investment security prepayment levels, depositor behavior, yield curve changes, loan and deposit pricing, and overall balance sheet mix and growth. In the +200 scenario, assumptions related to loan growth are based on historical experience. Because deposit balances have continued to grow significantly in this persistent low rate environment, historical depositor behavior may be less indicative of future trends. As a result, the June 30, 2015 +200 scenario now reflects a greater decrease in deposits than we have experienced historically as rates begin to rise. Investment securities modeling includes the replacement of prepayments as well as an estimate of projected growth in High Quality Liquid Assets (HQLA) needed for compliance with the LCR, and expected funding maturities are included. In addition, the model reflects deposit pricing based on historical price movements with short-term interest rates, and loan spreads are held at current levels. Changes in actual economic activity may result in a materially different interest rate environment as well as a balance sheet structure that is different from the changes management included in its simulation analysis.
The table below, as of June 30, 2015 and December 31, 2014, displays the estimated impact on net interest income during the next 12 months by relating the base case scenario results to those from the rising and declining rate scenarios described above.

Sensitivity decreased slightly from December 31, 2014 to June 30, 2015 primarily due to changes in the current balance sheet mix driving a revised forecast, offset by the impact from the addition of HQLA for the LCR and the modeled reduction in deposit growth in the +200 scenario discussed above. The risk to declining interest rates is limited as a result of the inability of the current low level of rates to fall significantly.

The table below, as of June 30, 2015, illustrates the estimated sensitivity of the above results to a change in deposit balance assumptions in the +200 scenario, with all other assumptions held constant. In this analysis, average noninterest-bearing deposit run-off in the 12-month period has been increased by $1 billion and $3 billion from the historical run-off experience included in the standard +200 scenario presented above and assumes the deposit run-off reduces excess reserves and increases purchased funds. The analysis is provided as an indicator of the sensitivity of net interest income to the modeled deposit run-off assumption. It is not meant to reflect management's expectation or best estimate. Actual deposit levels may vary from those reflected.

Sensitivity of Economic Value of Equity to Changes in Interest Rates
In addition to the simulation analysis on net interest income, an economic value of equity analysis provides an alternative view of the interest rate risk position. The economic value of equity is the difference between the estimate of the economic value of the Corporation's financial assets, liabilities and off-balance sheet instruments, derived through discounting cash flows based on actual rates at the end of the period and the estimated economic value after applying the estimated impact of rate movements. The economic value of equity analysis is based on an immediate parallel 200 basis point increase and 25 basis point decrease in interest rates.
The table below, as of June 30, 2015 and December 31, 2014, displays the estimated impact on the economic value of equity from the interest rate scenario described above.

The change in the sensitivity of the economic value of equity to a 200 basis point parallel increase in rates between December 31, 2014 and June 30, 2015 was primarily driven by changes in market interest rates at the middle to long end of the curve, which most significantly impact the value of deposits without a stated maturity.
Wholesale Funding
The Corporation may access the purchased funds market when necessary, which includes foreign office time deposits and short-term borrowings. Capacity for incremental purchased funds at June 30, 2015 included the ability to purchase federal funds, sell securities under agreements to repurchase, as well as issue deposits to institutional investors and issue certificates of deposit through brokers. Purchased funds totaled $155 million at June 30, 2015, compared to $251 million at December 31, 2014. At June 30, 2015, the Bank had pledged loans totaling $26 billion which provided for up to $20 billion of available collateralized borrowing with the FRB.
The Bank is a member of the FHLB of Dallas, Texas, which provides short- and long-term funding to its members through advances collateralized by real estate-related assets. Actual borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. At June 30, 2015, real estate-related loans pledged to the FHLB as blanket collateral provided for potential future borrowings of approximately $6 billion. As of June 30, 2015, the Corporation did not have any outstanding borrowings from the FHLB. Additionally, as of June 30, 2015 the Bank had the ability to issue up to $14.5 billion of debt under an existing $15 billion note program which allows the issuance of debt with maturities between three months and 30 years.The Corporation also maintains a shelf registration statement with the Securities and Exchange Commission from which it may issue debt and/or equity securities.

The ability of the Corporation and the Bank to raise funds at competitive rates is impacted by rating agencies' views of the credit quality, liquidity, capital and earnings of the Corporation and the Bank. As of June 30, 2015, the four major rating agencies had assigned the following ratings to long-term senior unsecured obligations of the Corporation and the Bank. A security rating is not a recommendation to buy, sell, or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be evaluated independently of any other rating.

In March 2015, Moody's Investors Service put global bank ratings on review following the publication of revised bank rating methodology. While the outlook for both Comerica Incorporated and Comerica Bank continue to be "Stable", Moody’s released a preliminary indication of an “A3” rating for Comerica Bank long-term senior unsecured debt.
The Corporation satisfies liquidity requirements with either liquid assets or various funding sources. Liquid assets, which totaled $13.5 billion at June 30, 2015, compared to $13.3 billion at December 31, 2014, provide a reservoir of liquidity. Liquid assets include cash and due from banks, federal funds sold, interest-bearing deposits with banks, other short-term investments and unencumbered investment securities. At June 30, 2015, the Corporation held deposits at the FRB of $4.6 billion, compared to $4.9 billion at December 31, 2014.
In September 2014, U.S. banking regulators issued a final rule implementing a quantitative liquidity requirement in the U.S. generally consistent with the LCR minimum liquidity measure established under the Basel III liquidity framework. Under the rule, the Corporation is subject to a modified LCR standard, which requires a financial institution to hold a minimum level of HQLA to fully cover modified net cash outflows under a 30-day systematic liquidity stress scenario. The rule is effective for the Corporation on January 1, 2016. During the transition year, 2016, the Corporation will be required to maintain a minimum LCR of 90 percent. Beginning January 1, 2017, and thereafter, the minimum required LCR will be 100 percent.
In the second quarter 2015, the Bank issued $500 million of senior debt maturing in 2020 and swapped it to floating at six-month LIBOR plus 75 basis points. Of the proceeds, $200 million was invested in five-year Treasury notes. To reach full compliance with the LCR rule and provide a buffer for normal volatility in balance sheet dynamics, the Corporation expects to add up to $3 billion of additional HQLA over the next 18 months, which may be funded with additional wholesale funds in manageable increments, tapping a variety of sources. On July 22, 2015, the Bank issued $350 million of 4.00% subordinated notes, swapped to floating at 6-month LIBOR plus 1.478%, due July 27, 2025 and $175 million of 2.50% senior notes, swapped to floating at 6-month LIBOR plus 0.6348%, due June 2, 2020. The proceeds of both issuances will assist the Corporation in meeting its LCR target.
The Basel III liquidity framework includes a second minimum liquidity measure, the Net Stable Funding Ratio (NSFR), which requires the amount of available longer-term, stable sources of funding to be at least 100 percent of the required amount of longer-term stable funding over a one-year period. On October 31, 2014, the Basel Committee on Banking Supervision issued its final NSFR rule, which was originally introduced in 2010 and revised in January 2014. U.S. banking regulators have announced that they expect to issue proposed rules to implement the NSFR in advance of its scheduled global implementation in 2018. While uncertainty exists in the final form and timing of the U.S. rule implementing the NSFR and whether or not the Corporation will be subject to the full requirements, the Corporation is closely monitoring the development of the rule.
The Corporation regularly evaluates its ability to meet funding needs in unanticipated, stressed environments. In conjunction with the quarterly 200 basis point interest rate simulation analyses, discussed in the “Interest Rate Sensitivity” section of this financial review, liquidity ratios and potential funding availability are examined. Each quarter, the Corporation also evaluates its ability to meet liquidity needs under a series of broad events, distinguished in terms of duration and severity. The evaluation as of June 30, 2015 projected that sufficient sources of liquidity were available under each series of events.
CRITICAL ACCOUNTING POLICIES
The Corporation’s consolidated financial statements are prepared based on the application of accounting policies, the most significant of which are described in Note 1 to the consolidated financial statements included in the Corporation's 2014 Annual Report. These policies require numerous estimates and strategic or economic assumptions, which may prove inaccurate or subject to variations. Changes in underlying factors, assumptions or estimates could have a material impact on the Corporation’s future financial condition and results of operations. At December 31, 2014, the most critical of these significant accounting policies were the policies related to the allowance for credit losses, valuation methodologies, goodwill, pension plan accounting and income taxes. These policies were reviewed with the Audit Committee of the Corporation’s Board of Directors and are discussed more

n/a - not applicable.
The Tier 1 common capital ratio removes preferred stock and qualifying trust preferred securities from Tier 1 capital as defined by and calculated in conformity with Basel I risk-based capital rules in effect through December 31, 2014. Effective January 1, 2015, regulatory capital components and risk-weighted assets are defined by and calculated in conformity with Basel III risk-based capital rules. The tangible common equity ratio removes preferred stock and the effect of intangible assets from capital and the effect of intangible assets from total assets and tangible common equity per share of common stock removes the effect of intangible assets from common shareholders' equity per share of common stock. The Corporation believes these measurements are meaningful measures of capital adequacy used by investors, regulators, management and others to evaluate the adequacy of common equity and to compare against other companies in the industry.
