1.  Basis of Presentation

The Company

American Express Company (the Company) is a global services company that provides customers with access to products, insights and experiences that enrich lives and build business success. The Company’s principal products and services are charge and credit payment card products and travel-related services offered to consumers and businesses around the world. Business travel-related services are offered through the non-consolidated joint venture, American Express Global Business Travel (the GBT JV). The Company’s various products and services are sold globally to diverse customer groups, including consumers, small businesses, mid-sized companies and large corporations. These products and services are sold through various channels, including direct mail, online applications, in-house and third-party sales forces and direct response advertising.

The accompanying Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (the Annual Report). If not materially different, certain footnote disclosures included therein have been omitted from this Quarterly Report on Form 10-Q.

The interim consolidated financial information in this report has not been audited. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period consolidated financial information, have been made. Results of operations reported for interim periods are not necessarily indicative of results for the entire year.

The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. These accounting estimates reflect the best judgment of management, but actual results could differ.

Certain reclassifications of prior period amounts have been made to conform to the current period presentation.

Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (FASB) issued new accounting guidance on revenue recognition. The accounting standard establishes the principles to apply to determine the amount and timing of revenue recognition, specifying the accounting for certain costs related to revenue, and requiring additional disclosures about the nature, amount, timing and uncertainty of revenues and related cash flows. The guidance, as amended, supersedes most of the current revenue recognition requirements, and is effective January 1, 2018.

Upon adoption of the new revenue recognition guidance, the Company anticipates using the full retrospective method, which applies the new standard to each prior reporting period presented. The Company has been working on the implementation of the standard since its issuance in 2014 and has made significant progress in evaluating the potential impact on its Consolidated Financial Statements. There will be changes to the recognition timing and classification of revenues and expenses, including potential changes to the presentation of certain credit and charge card related costs that are currently netted against discount revenue. The Company does not expect a significant impact to pretax income upon adoption. The Company is also in the process of implementing changes to its accounting policies, business processes, systems and internal controls to support the recognition, measurement and disclosure requirements under the new standard.

In January 2016, the FASB issued new accounting guidance on the recognition and measurement of financial assets and financial liabilities. The guidance, which is effective January 1, 2018, makes targeted changes to current GAAP, specifically to the classification and measurement of equity securities, and to certain disclosure requirements associated with the fair value of financial instruments. In the ordinary course of business, the Company makes investments in non-public companies currently recognized under cost method accounting.  Under the new guidance, these investments will be prospectively adjusted for observable price changes upon identification of identical or similar transactions of the same issuer. The Company continues to evaluate the impact this guidance will have on its financial position, results of operations and cash flows, as well as the impact the standard will have on its accounting policies, business processes, systems and internal controls.

(Unaudited)

In February 2016, the FASB issued new accounting guidance on leases. The guidance, which is effective January 1, 2019, with early adoption permitted, requires virtually all leases to be recognized on the Consolidated Balance Sheets. The Company currently anticipates adopting the standard effective January 1, 2019, using the modified retrospective approach, which requires recording existing operating leases on the Consolidated Balance Sheets upon adoption and in the comparative period. The Company is in the process of upgrading its existing lease administration software for new lease accounting functionality, business processes and internal controls in preparation for the implementation. Specifically, the Company is currently reviewing its lease portfolio and is evaluating and interpreting the requirements under the guidance, including the available accounting policy elections, in order to determine the impacts to the Company’s financial position, results of operations and cash flows upon adoption.

In June 2016, the FASB issued new accounting guidance for recognition of credit losses on financial instruments, which is effective January 1, 2020, with early adoption permitted on January 1, 2019. The guidance introduces a new credit reserving model known as the Current Expected Credit Loss (CECL) model, which is based on expected losses, and differs significantly from the incurred loss approach used today. The CECL model requires measurement of expected credit losses not only based on historical experience and current conditions, but also by including reasonable and supportable forecasts incorporating forward-looking information. The guidance requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption. The Company does not intend to adopt the new standard early and is currently evaluating the impact the new guidance will have on its financial position, results of operations and cash flows; however, it is expected that the CECL model will alter the assumptions used in estimating credit losses on Card Member loans and receivables, among other financial instruments (e.g., investments in available-for-sale debt securities), and may result in material increases to the Company’s credit reserves as the new guidance involves earlier recognition of expected losses for the life of the assets. The Company has established an enterprise-wide, cross-discipline governance structure to implement the new standard. The Company is currently identifying key interpretive issues, and is evaluating existing credit loss forecasting models and processes in relation to the new guidance to determine what modifications may be required.

2.  Business Events

During the fourth quarter of 2015, it was determined the Company would sell the Card Member loans and receivables related to its cobrand partnerships with JetBlue Airways Corporation (JetBlue) and Costco Wholesale Corporation (Costco) in the United States (the HFS portfolios). As a result, the HFS portfolios were presented as held for sale (HFS) on the Consolidated Balance Sheets within Card Member loans and receivables HFS as of December 31, 2015.

During the first half of 2016, the Company completed the sales of substantially all of its outstanding Card Member loans and receivables HFS and recognized gains, as an expense reduction, in Other expenses, of $127 million and $1.1 billion during the three months ended March 31, 2016 and June 30, 2016, respectively. The impact of the sales, including the recognition of the proceeds received and the reclassification of the retained Card Member loans and receivables, is reported within the investing section of the Consolidated Statements of Cash Flows as a net decrease in Card Member receivables and loans, including HFS.

From the point of classification as HFS through the sale completion dates, the Company continued to recognize discount revenue, interest income, other revenues and expenses related to the HFS portfolios in the respective line items on the Consolidated Statements of Income, with changes in the valuation of the HFS portfolios recognized in Other expenses.

(a) For Global Corporate Payments (GCP) Card Member loans and receivables in Global Commercial Services (GCS), delinquency data is tracked based on days past billing status rather than days past due. A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member’s billing statement date. In addition, if the Company initiates collection procedures on an account prior to the account becoming 90 days past billing, the associated Card Member loan and receivable balance is classified as 90 days past billing. These amounts are shown above as 90+ Days Past Due for presentation purposes. See also (b).

(b) Delinquency data for periods other than 90 days past billing is not available due to system constraints. Therefore, such data has not been utilized for risk management purposes. The balances that are current to 89 days past due can be derived as the difference between the Total and the 90+ Days Past Due balances.

In addition, because the Company considers uncollectible interest and/or fees in estimating its reserves for credit losses, a net write-off rate including principal, interest and/or fees is also presented.

Impaired Card Member Loans and Receivables

Impaired Card Member loans and receivables are individual larger balance or homogeneous pools of smaller balance loans and receivables for which it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the Card Member agreement. In certain cases, these Card Member loans and receivables are included in one of the Company’s various Troubled Debt Restructuring (TDR)modification programs.

5.  Investment Securities

Investment securities principally include debt securities the Company classifies as available-for-sale and carries at fair value on the Consolidated Balance Sheets, with unrealized gains and losses recorded in accumulated other comprehensive income (loss) (AOCI), net of income taxes. Realized gains and losses are recognized upon disposition of the securities using the specific identification method.

The following is a summary of investment securities as of June 30, 2017 and December 31, 2016:

The gross unrealized losses are attributed to overall wider credit spreads for specific issuers, adverse changes in market benchmark interest rates, or a combination thereof, all compared to those prevailing when the investment securities were acquired.

Overall, for the investment securities in gross unrealized loss positions, (i) the Company does not intend to sell the investment securities, (ii) it is more likely than not that the Company will not be required to sell the investment securities before recovery of the unrealized losses, and (iii) the Company expects that the contractual principal and interest will be received on the investment securities. As a result, the Company recognized no other-than-temporary impairment during the periods presented.

Contractual maturities for investment securities with stated maturities as of June 30, 2017 were as follows:

			Estimated
(Millions)	Cost		Fair Value
Due within 1 year	$	623	$	623
Due after 1 year but within 5 years		979		984
Due after 5 years but within 10 years		294		298
Due after 10 years		1,390		1,406
Total	$	3,286	$	3,311

The expected payments on state and municipal obligations and mortgage-backed securities may not coincide with their contractual maturities because the issuers have the right to call or prepay certain obligations.

6.  Asset Securitizations

The Company periodically securitizes Card Member loans and receivables arising from its card businesses through the transfer of those assets to securitization trusts. The trusts then issue debt securities collateralized by the transferred assets to third-party investors.

The following table provides information on the restricted cash held by the American Express Credit Account Master Trust (the Lending Trust) and the American Express Issuance Trust II (the Charge Trust, collectively the Trusts) as of June 30, 2017 and December 31, 2016, included in Other assets on the Consolidated Balance Sheets:

(Millions)	2017		2016
Lending Trust	$	53	$	35
Charge Trust		2		3
Total	$	55	$	38

These amounts relate to collections of Card Member loans and receivables to be used by the Trusts to fund future expenses and obligations, including interest on debt securities, credit losses and upcoming debt maturities.

American Express Travel Related Services Company, Inc. (TRS), in its role as servicer of the Trusts, has the power to direct the activities that most significantly impact the Trusts’ economic performance, which are the collection of the underlying Card Member loans and receivables. In addition, TRS directly and indirectly (through its consolidated subsidiaries) holds all of the variable interests in both Trusts, with the exception of the debt securities issued to third-party investors.  As of June 30, 2017, TRS’ direct and indirect ownership of variable interests was $9.8 billion for the Lending Trust and $6.5 billion for the Charge Trust. These variable interests held by TRS provide it with the right to receive benefits and the obligation to absorb losses, which could be significant to both the Lending Trust and the Charge Trust. Based on these considerations, TRS is the primary beneficiary of both Trusts and therefore consolidates both Trusts.

Under the respective terms of the Lending Trust and the Charge Trust agreements, the occurrence of certain triggering events associated with the performance of the assets of each Trust could result in payment of trust expenses, establishment of reserve funds, or, in a worst-case scenario, early amortization of debt securities. During the six months ended June 30, 2017 and the year ended December 31, 2016, no such triggering events occurred.

8.  Contingencies

In the ordinary course of business, the Company and its subsidiaries are subject to various pending and potential legal actions, arbitration proceedings, claims, investigations, examinations, information gathering requests, subpoenas, inquiries and matters relating to compliance with laws and regulations (collectively, legal proceedings). The Company discloses its material legal proceedings under Part II, Item 1. “Legal Proceedings” in this Quarterly Report on Form 10-Q and Part I, Item 3. “Legal Proceedings” in the Annual Report.

In addition to the matters disclosed under “Legal Proceedings,” the Company is being challenged in a number of countries regarding its application of value-added taxes (VAT) to certain of its international transactions, which are in various stages of audit, or are being contested in legal actions (collectively, VAT matters). While the Company believes it has complied with all applicable tax laws, rules and regulations in the relevant jurisdictions, the tax authorities may determine that the Company owes additional VAT. In certain jurisdictions where the Company is contesting the assessments, it was required to pay the VAT assessments prior to contesting.

The Company’s legal proceedings range from cases brought by a single plaintiff to class actions with millions of putative class members. These legal proceedings involve various lines of business of the Company and a variety of claims (including, but not limited to, common law tort, contract, application of tax laws, antitrust and consumer protection claims), some of which present novel factual allegations and/or unique legal theories. While some matters pending against the Company specify the damages claimed by the plaintiff or class, many seek an unspecified amount of damages or are at very early stages of the legal process. Even when the amount of damages claimed against the Company are stated, the claimed amount may be exaggerated and/or unsupported. As a result, some matters have not yet progressed sufficiently through discovery and/or development of important factual information and legal issues to enable the Company to estimate an amount of loss or a range of possible loss, while other matters have progressed sufficiently such that the Company is able to estimate an amount of loss or a range of possible loss.

The Company has recorded reserves for certain of its outstanding legal proceedings. A reserve is recorded when it is both (a) probable that a loss has occurred and (b) the amount of loss can be reasonably estimated. There may be instances in which an exposure to loss exceeds the recorded reserve. The Company evaluates, on a quarterly basis, developments in legal proceedings that could cause an increase or decrease in the amount of the reserve that has been previously recorded, or a revision to the disclosed estimated range of possible losses, as applicable.

For those disclosed material legal proceedings and VAT matters where a loss is reasonably possible in future periods, whether in excess of a related reserve for legal or tax contingencies or where there is no such reserve, and for which the Company is able to estimate a range of possible loss, the current estimated range is zero to $450 million in excess of any reserves related to those matters. This range represents management’s estimate based on currently available information and does not represent the Company’s maximum loss exposure; actual results may vary significantly. As such legal proceedings evolve, the Company may need to increase its range of possible loss or reserves.

Based on its current knowledge, and taking into consideration its litigation-related liabilities, the Company believes it is not a party to, nor are any of its properties the subject of, any legal proceeding that would have a material adverse effect on the Company’s consolidated financial condition or liquidity. However, in light of the uncertainties involved in such matters, it is possible that the outcome of legal proceedings, including the possible resolution of merchant claims, could have a material impact on the Company’s results of operations.

9.   Derivatives and Hedging Activities

The Company uses derivative financial instruments (derivatives) to manage exposures to various market risks. These instruments derive their value from an underlying variable or multiple variables, including interest rates, foreign exchange rates, and equity index or price, and are carried at fair value on the Consolidated Balance Sheets. These instruments enable end users to increase, reduce or alter exposure to various market risks and, for that reason, are an integral component of the Company’s market risk management. The Company does not transact in derivatives for trading purposes.

In relation to the Company’s credit risk, under the terms of the derivative agreements it has with its various counterparties, the Company is not required to either immediately settle any outstanding liability balances or post collateral upon the occurrence of a specified credit risk-related event. Based on its assessment of the credit risk of the Company’s derivative counterparties as of June 30, 2017 and December 31, 2016, no credit risk adjustment to the derivative portfolio was required.

The following table summarizes the total fair value, excluding interest accruals, of derivative assets and liabilities as of June 30, 2017 and December 31, 2016:

	Other Assets Fair Value						Other Liabilities Fair Value
(Millions)	2017			2016			2017			2016

Fair value hedges - Interest rate contracts(a)	$	39		$	111		$	―		$	69
Net investment hedges - Foreign exchange contracts		28			347			265			35
Total derivatives designated as hedging instruments		67			458			265			104
Derivatives not designated as hedging instruments:
Foreign exchange contracts, including certain embedded derivatives(b)		144			308			170			176
Total derivatives, gross		211			766			435			280

Total derivatives, net(f)	$	118		$	555		$	361		$	55

(a) Effective January 2017, the Central Clearing Party (CCP) changed the legal characterization of variation margin payments for centrally cleared derivatives to be settlement payments, as opposed to collateral. As of June 30, 2017 centrally cleared derivatives are fully collateralized. The Company also maintained several bilateral interest rate contracts that are not subject to the CCP’s rule change and amounts related to such contracts are shown gross of any collateral exchanged.

(b) Includes foreign currency derivatives embedded in certain operating agreements.

(c) Primarily represents the offsetting of bilateral interest rate contracts and the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from derivatives executed with the same counterparty under an enforceable master netting arrangement.

(d) The Company held no non-cash collateral as of June 30, 2017. As of December 31, 2016, the Company received non-cash collateral from a counterpartyin the form of security interests in U.S. Treasury securities,with a fair value of $18 million, none of which was sold or repledged.  Such non-cash collateral economically reduced the Company’s risk exposure to $537 million as of December 31, 2016, but did not reduce the net exposure on the Company’s Consolidated Balance Sheets. Additionally, the Company posted $170 million and $169 million as of June 30, 2017 and December 31, 2016, respectively, as initial margin on its centrally cleared interest rate swaps; such amounts are recorded within Other receivables on the Consolidated Balance Sheets and are not netted against the derivative balances.

(e) Represents the amount of netting of derivative assets and derivative liabilities executed with the same counterparty under an enforceable master netting arrangement.

(f) The Company has no individually significant derivative counterparties and therefore, no significant risk exposure to any single derivative counterparty. The total net derivative assets and net derivative liabilities are presented within Other assets and Other liabilities, respectively, on the Consolidated Balance Sheets.

A majority of the Company’s derivative assets and liabilities as of June 30, 2017 and December 31, 2016 are subject to master netting agreements with its derivative counterparties. The Company has no derivative amounts subject to enforceable master netting arrangements that are not offset on the Consolidated Balance Sheets.

Fair Value Hedges

The Company is exposed to interest rate risk associated with its fixed-rate long-term debt obligations. At the time of issuance, certain fixed-rate debt obligations are designated in fair value hedging relationships, using interest rate swaps, to economically convert the fixed interest rate to a floating interest rate. The Company has $19.5 billion and $17.7 billion of fixed-rate debt obligations designated in fair value hedging relationships as of June 30, 2017 and December 31, 2016, respectively.

The Company also recognized a net reduction in interest expense on long-term debt of $37  million and $59  million for the three months ended June 30, 2017 and 2016, respectively, and $81 million and $118 million for the six months ended June 30, 2017 and 2016, respectively, primarily related to the net settlements (interest accruals) on the Company’s interest rate derivatives designated as fair value hedges.

Net Investment Hedges

The effective portion of the gain or loss on net investment hedges, net of taxes, recorded in AOCI as part of the cumulative translation adjustment, was a loss of $102 million and a gain of $135 million for the three months ended June 30, 2017 and 2016, respectively, and a loss of $331 million and a gain of $43 million for the six months ended June 30, 2017 and 2016, respectively, with any ineffective portion recognized in Other expenses during the period. The net hedge ineffectiveness recognized was nil for each of the three and six months ended June 30, 2017 and 2016. Other amounts related to foreign exchange contracts reclassified from AOCI into Other expenses included nil and a gain of $5 million for the three months ended June 30, 2017 and 2016, respectively, and nil and a gain of $5 million for the six months ended June 30, 2017 and 2016, respectively.

Derivatives Not Designated as Hedges

The changes in the fair value of derivatives that are not designated as hedges are intended to offset the related foreign exchange gains or losses of the underlying foreign currency exposures. The changes in the fair value of the derivatives and the related underlying foreign currency exposures resulted in a net loss of $4 million and a net gain of $6 million for the three months ended June 30, 2017 and 2016, respectively, and net losses of $21 million and $8 million for the six months ended June 30, 2017 and 2016, respectively, and are recognized in Other expenses.

The changes in the fair value of an embedded derivative resulted in a loss of $3 million and nil for the three months ended June 30, 2017 and 2016, respectively, and a loss of $2 million and a gain of $6 million for the six months ended June 30, 2017 and 2016, respectively, which are recognized in Card Member services and other expense.

11. Guarantees

The Company provides Card Member protection plans that cover losses associated with purchased products, as well as certain guarantees and indemnifications in the ordinary course of business.

As of June 30, 2017, the maximum potential undiscounted future payments and related liability resulting from these arrangements were $1 billion and $50 million, respectively, and related primarily to the Company’s real estate and business dispositions. As of December 31, 2016, the maximum potential undiscounted future payments and related liability were $48 billion and $86 million, respectively. Amounts related to the Company’s Card Member protection plans were included as of December 31, 2016, in addition to its real estate and business dispositions.

To date the Company has not experienced any significant losses related to guarantees or indemnifications. The Company’s recognition of these instruments is at fair value. In addition, the Company establishes reserves when a loss is probable and the amount can be reasonably estimated.

14.  Income Taxes

The effective tax rate was 31.2 percent and 33.2 percent for the three months ended June 30, 2017 and 2016, respectively, and 31.6 percent and 33.8 percent for the six months ended June 30, 2017 and 2016, respectively. The changes in tax rates primarily reflected the geographic mix of business and the level of pretax income in relation to recurring permanent tax benefits. In addition, the effective tax rate in the current year reflected the resolution of certain prior years’ tax items.

The Company is under continuous examination by the Internal Revenue Service (IRS) and tax authorities in other countries and states in which the Company has significant business operations. The tax years under examination and open for examination vary by jurisdiction.  In February 2017, the Company received notification that all matters outstanding with the IRS for tax years 1997-2007 were resolved.  The resolution of such matters did not have a material impact on the Company’s effective tax rate.  The Company is currently under examination with the IRS for tax years 2008 through 2014.

The Company believes it is reasonably possible that its unrecognized tax benefits could decrease within the next 12 months by as much as $133 million, principally as a result of potential resolutions of prior years’ tax items with various taxing authorities. The prior years’ tax items include unrecognized tax benefits relating to the deductibility of certain expenses or losses and the attribution of taxable income to a particular jurisdiction or jurisdictions.  Of the $133 million of unrecognized tax benefits, approximately $90 million relates to amounts that, if recognized, would impact the effective tax rate in a future period. During the six months ended June 30, 2017, the Company’s unrecognized tax benefits decreased by $280 million. The decrease was primarily due to the resolution with the IRS of an uncertain tax position in January 2017, which resulted in the recognition of $289 million in shareholders’ equity, specifically within AOCI.

(a) The Company’s unvested restricted stock awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator.

(b) The dilutive effect of unexercised stock options excludes from the computation of EPS 1.2 million and 2.5 million of options for the three months ended June 30, 2017 and 2016, respectively, and 1.2 million and 1.7 million of options for the six months ended June 30, 2017 and 2016, respectively, because inclusion of the options would have been anti-dilutive.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Business Introduction

When we use the terms “American Express,” “the Company,” “we,” “our” or “us,” we mean American Express Company and its subsidiaries on a consolidated basis, unless we state or the context implies otherwise.

We are a global services company with four reportable operating segments: U.S. Consumer Services (USCS), International Consumer and Network Services (ICNS), Global Commercial Services (GCS) and Global Merchant Services (GMS). Corporate functions and certain other businesses and operations are included in Corporate & Other. We provide our customers with access to products, insights and experiences that enrich lives and build business success. Our principal products and services are charge and credit payment card products and travel-related services offered to consumers and businesses around the world. Our range of products and services includes:

•     Charge card, credit card and other payment and financing products

•     Network services

•     Merchant acquisition and processing, servicing and settlement, marketing and point-of-sale marketing and information products and services for merchants

•     Other fee services, including fraud prevention services and the design and operation of customer loyalty programs

•     Expense management products and services

•     Travel-related services

•     Stored-value/prepaid products

Our various products and services are sold globally to diverse customer groups, including consumers, small businesses, mid-sized companies and large corporations. These products and services are sold through various channels, including online applications, direct mail, in-house teams, third-party vendors and direct response advertising. Business travel-related services are offered through our non-consolidated joint venture, American Express Global Business Travel (the GBT JV).

We compete in the global payments industry with charge, credit and debit card networks, issuers and acquirers, paper-based transactions (e.g., cash and checks), bank transfer models (e.g., wire transfers and ACH), as well as evolving and growing alternative payment and financing providers. As the payments industry continues to evolve, we face increasing competition from non-traditional players that leverage new technologies and customer relationships to create payment or financing solutions.

The following types of revenue are generated from our various products and services:

• Discount revenue, our largest revenue source, represents fees generally charged to merchants for accepting our cards as payment for goods or services sold;

• Interest on loans, principally represents interest income earned on outstanding balances;

• Net card fees, represent revenue earned from annual card membership fees, which varies based on the type of card and the number of cards for each account;

• Other fees and commissions, represent foreign currency conversion fees charged to Card Members, Card Member delinquency fees, loyalty coalition-related fees, travel commissions and fees, service fees and fees related to our Membership Rewards program; and

• Other revenue, primarily represents revenues arising from contracts with partners of our Global Network Services (GNS) business (including commissions and signing fees), cross-border Card Member spending, insurance premiums earned from Card Members, ancillary merchant-related fees, revenues related to the GBT JV transition services agreement, prepaid card and Travelers Cheque-related revenue and earnings from equity method investments (including the GBT JV).

Forward-Looking Statements and Non-GAAP Measures

Certain of the statements in this Form 10-Q are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Refer to the “Cautionary Note Regarding Forward-Looking Statements” section. We prepare our Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America (GAAP). However, certain information included within this Form 10-Q constitutes non-GAAP financial measures. Our calculations of non-GAAP financial measures may differ from the calculations of similarly titled measures by other companies.

Bank Holding Company

American Express Company is a bank holding company under the Bank Holding Company Act of 1956 and The Board of Governors of the Federal Reserve System (the Federal Reserve) is our primary federal regulator. As such, we are subject to the Federal Reserve’s regulations, policies and minimum capital standards.

Business Environment

Our results for the second quarter continue to reflect solid progress against our current priorities of accelerating revenue growth, optimizing investments and resetting the cost base.  Billed business and revenue for the second quarter increased slightly, while net income was down. The prior year quarter included revenues and expenses related to the Costco Wholesale Corporation (Costco) relationship in the U.S. that has since been discontinued, the gain from the sale of the related loan portfolio and a restructuring charge. During the current quarter, our strong balance sheet position allowed us to continue to return a significant amount of capital to shareholders through share repurchases and dividends.

Our worldwide billings adjusted for foreign currency exchange rates increased and, after excluding Costco-related billings from the prior year, grew consistent with the first quarter, reflecting growth across our diverse customer segments and geographies. We continued to see strong performance from middle market and small business customers, while spending by large corporations was up only slightly compared to last year. Internationally, our consumer and small business billings growth rates remained strong.

Revenues net of interest expense increased slightly year-over-year on a reported basis. Excluding Costco-related revenues in the prior year and the effect of foreign currency exchange rates, adjusted revenues net of interest expense grew primarily due to an increase in net interest income and higher adjusted billed business, as well as higher net card fees across our premium card portfolios.  Our net interest yield increased year-over-year, due to a mix shift towards non-cobrand lending products, where Card Members tend to revolve more of their loan balances, as well as a lower percentage of loans at introductory rates, specific pricing actions, and a benefit from increases in benchmark interest rates.

Card Member loan and receivable growth was strong year-over-year, as we continue to grow loans from existing customers, as well as through the acquisition of new Card Members. Provisions for losses increased, as expected, as a result of higher Card Member loans and receivables, as well as a slight increase in delinquencies and higher net write-off rates. These rates increased, primarily due to the seasoning of loans related to newer Card Members and a shift towards non-cobrand lending products, which have slightly higher write-off rates. We expect, as a result of these trends, provisions for losses will continue to grow faster than loans during the balance of the year.

Spending on Card Member engagement (the aggregate of rewards, Card Member services and marketing and promotion expenses) increased year-over-year and primarily reflected the recent enhancements to rewards on our U.S. Platinum products, continued strong growth in our Delta cobrand portfolio and higher levels of engagement in many of our premium services.  Operating expenses increased, primarily as a result of the Costco cobrand portfolio sale gain in the prior year, which was classified as an expense reduction in Other expenses.  Excluding the gain and the restructuring charge in the prior year, adjusted operating expenses decreased reflecting progress against our cost reduction initiatives.

The momentum in the first half of the year reflects the investments we have made in a variety of growth opportunities over the last several years. Although competition remains intense and the regulatory environment is uncertain, we remain focused on delivering differentiated value to our merchants, customers and business partners, while delivering appropriate returns to our shareholders.

See “Certain legislative, regulatory and other developments” in “Other Matters” for information on legislative and regulatory changes that could have a material adverse effect on our results of operations and financial condition.

Consolidated Results of Operations

Refer to the “Glossary of Selected Terminology” for the definitions of certain key terms and related information appearing within this section.

Effective December 1, 2015, we transferred the Card Member loans and receivables related to our cobrand partnerships with Costco and JetBlue Airways Corporation (JetBlue) (collectively, the HFS portfolios) to Card Member loans and receivables HFS on the Consolidated Balance Sheets. On March 18, 2016 and June 17, 2016, we completed the sales of the JetBlue and Costco cobrand card portfolios, respectively. For the periods from December 1, 2015, through the sale completion dates, the primary impacts beyond the HFS classification on the Consolidated Balance Sheets were to provisions for losses and credit metrics, which do not reflect amounts related to these HFS loans and receivables, as credit costs were reported in Other expenses through a valuation allowance adjustment. Other, non-credit related metrics (i.e., billed business, cards-in-force, net interest yield) reflect amounts related to the HFS portfolios through the sale completion dates. Additionally, for periods after the sale completion dates, activities associated with these cobrand partnerships and the HFS portfolios are no longer included in our Consolidated Results of Operations. Specifically, these impacts include: Discount revenue from Costco in the United States for spend on all American Express cards and from other merchants for spend on the Costco cobrand card; Other fees and commissions and Interest income from Costco cobrand Card Members; and Card Member rewards expense related to the Costco cobrand card, resulting in a lack of comparability between 2017 and 2016.

The discussions in both the Consolidated Results of Operations and Business Segment Results provide commentary on the variances for the three and six month periods ended June 30, 2017 compared to same periods in the prior year, as presented in the accompanying tables.

Total Revenues Net of Interest Expense

Discount revenue was flat for the three month period and decreased slightly for the six month period, primarily driven by Costco-related revenue included in the prior year, substantially offset by billed business growth across other card products in the current periods.

Worldwide billed business was flat for both the three and six month periods. U.S. billed business decreased 4 percent and 5 percent for the three and six month periods respectively, primarily driven by Costco-related volumes in the prior year. Non-U.S. billed business increased 9 percent and 11 percent for the three and six month periods, respectively. See Tables 5, 6 and 7 for more details on billed business performance.

The increase in the average discount rate for both the three and six month periods primarily reflected the absence of Costco merchant volumes in the current year, which were at a lower discount rate than the average, partially offset by rate pressure from merchant negotiations, including those resulting from the recent regulatory changes affecting competitor pricing in the European Union, changes in industry and regional mix and the continued growth of the OptBlue program. We expect the average discount rate will likely decline over time due to a greater shift of existing merchants into OptBlue, merchant negotiations and competition, volume related pricing discounts and certain pricing initiatives mainly driven by pricing regulation (including regulation of competitors’ interchange rates).

Net card fees increased for both the three and six month periods, primarily driven by growth in the Platinum and Delta portfolios as well as growth in certain key international markets.

Other fees and commissions increased for both the three and six month periods, primarily driven by an increase in delinquency fees as a result of a change in the date on which late fees are assessed on our U.S. consumer charge cards, partially offset by Costco-related fees in the prior year.

Other revenues decreased for both the three and six month periods, primarily driven by a contractual payment from a GNS partner and revenues related to our Loyalty Edge business, both in the prior year.

Interest income increased for both the three and six month periods, primarily driven by growth in average Card Member loans and higher yields in the current year, partially offset by Costco cobrand-related interest income included in the prior year.

Interest expense increased for both the three and six month periods, primarily driven by marginally higher interest rates and higher average long-term debt.

Provisions for Losses

Charge card provision for losses increased for both the three and six month periods, primarily driven by growth in charge volume in the GCS segment and higher net write-offs.

Card Member loans provision for losses increased for both the three and six month periods, primarily driven by strong momentum in our lending growth initiatives, as well as a slight increase in delinquencies and higher net write-off rates, primarily due to the seasoning of loans related to newer Card Members and a shift towards non-cobrand lending products, which have slightly higher write-off rates.

31

Other provision for losses decreased for both the three and six month periods, primarily driven by improving credit performance in the commercial financing portfolio.

# Denotes a variance greater than 100 percent.

(a) Beginning December 1, 2015 through to the portfolio sale completion dates, includes the valuation allowance adjustment associated with the HFS portfolios.

Expenses

Marketing and promotion expenses increased marginally during the three month period and were relatively flat during the six month period.

Card Member rewards expenses increased for both the three and six month periods, primarily driven by an increase in Membership Rewards expense of $243 million and $472 million for the three and six month periods, respectively, partially offset by a reduction in cobrand rewards expense of $84 million and $208 million for the same respective periods. The increases in Membership Rewards expense were primarily driven by enhancements to U.S. Consumer and Small Business Platinum rewards and higher spending volumes. The decreases in cobrand rewards expense reflected Costco-related expenses in the prior year, partially offset by increased spending volumes across other cobrand card products in the current periods.

The Membership Rewards Ultimate Redemption Rate (URR) for current program participants was 95 percent (rounded down) at both June 30, 2017 and 2016.

Card Member services and other expenses increased for both the three and six month periods, primarily driven by higher usage of cobrand travel-related benefits and the enhanced Platinum card benefits.

Salaries and employee benefits expenses decreased for both the three and six month periods, reflecting restructuring charges in the prior year and benefits from our cost reduction initiatives in the current year.

Other expenses increased for both the three and six month periods, primarily driven by the prior-year gain on the sale of the Costco HFS portfolio and, in the six month period, the gain on the sale of the JetBlue HFS portfolio, also in the prior year. The increases were partially offset by lower technology-related costs and a benefit in the current year from a change in the liability related to non-delivery of goods and services by merchants, as well as the HFS valuation allowance adjustment, Loyalty Edge-related costs and a contribution to the AXP Foundation in the prior year.

Income Taxes

The effective tax rate decreased for both the three and six month periods, primarily reflecting the geographic mix of business and the level of pretax income in relation to recurring permanent tax benefits. In addition, the effective tax rates in the current year periods reflected the resolution of certain prior years’ tax items in the six month period.

USCS issues a wide range of proprietary consumer cards and provides services to consumers in the United States, including consumer travel services.

Non-interest revenues decreased for both the three and six month periods, primarily due to lower discount revenue, which decreased $124 million and $325 million for the three and six month periods, respectively, reflecting decreases in billed business of 9 percent and 11 percent for the three and six month periods, respectively. The decreases in both discount revenue and billed business were driven by Costco-related volumes included in the prior year. The decreases in discount revenue were partially offset, in both the three and six month periods, by an increase in net card fees, primarily from growth in the Platinum and Delta portfolios, as well as higher delinquency fees.

Net interest income increased for the three month period and was relatively flat for the six month period, primarily driven by growth in average Card Member loans and higher yields in the current year, offset (partially in the case of the three month period) by Costco cobrand-related interest income included in the prior year and higher interest expense in the current year, primarily driven by higher cost of funds.

Provisions for losses increased for both the three and six month periods, primarily driven by Card Member loans provision, which increased $97 million and $177 million in the three and six month periods, respectively, due to strong momentum in our lending growth initiatives, as well as slight increases in delinquencies and higher net write-off rates primarily due to the seasoning of loans related to newer Card Members and a shift towards non-cobrand lending products, which have slightly higher write-off rates.

38

Marketing, promotion, rewards, Card Member services and other expenses increased for both the three and six month periods, reflecting higher marketing and promotion and Card Member services and other expenses in both periods, partially offset in the six month period by a decrease in Card Member rewards expenses. Marketing and promotion expenses increased $59 million and $38 million for the three and six month periods, respectively, due to continued spending on growth initiatives. Card Member services and other expenses increased $37 million and $56 million for the three and six month periods, respectively, driven by higher usage of cobrand travel-related benefits and enhanced Platinum card benefits.  Card Member rewards expense increased $4 million for the three month period and decreased $45 million for the six month period, reflecting Costco-related expenses in the prior year, which were more than offset in the three month period by enhancements to Platinum rewards and increased spending volumes.

Salaries and employee benefits and other operating expenses increased for both the three and six month periods, primarily driven by the prior-year gain on the sale of the Costco HFS portfolio, partially offset by lower technology and other servicing-related costs in the current year and the prior year HFS valuation allowance adjustment and restructuring charges.

The effective tax rate was lower for both the three and six month periods, primarily reflecting the level of pretax income in relation to recurring permanent tax benefits and the resolution of certain prior years’ tax items in the six month period.

ICNS issues a wide range of proprietary consumer cards outside the United States and enters into partnership agreements with third-party card issuers and acquirers, licensing the American Express brand and extending the reach of the global network. It also provides travel services to consumers outside the United States.

Non-interest revenues were flat for the three month period and increased for the six month period, primarily driven by higher discount revenue in both periods, due to an increase in both proprietary and non-proprietary (i.e., GNS) billed business, as well as higher net card fees, offset in the three month period by a prior-year contractual payment from a GNS partner. Total billed business increased, for both the three and six months, reflecting higher cards-in-force and average spend per card. Refer to Tables 6, 7 and 13 for additional information on billed business.

Net interest income increased for both the three and six month periods, primarily driven by higher average loan balances.

Marketing, promotion, rewards, Card Member services and other expenses increased for both the three and six month periods, primarily driven by higher Card Member rewards expense due to higher spending volumes.

Salaries and employee benefits and other operating expenses decreased for both the three and six month periods, primarily driven by lower salaries and employee benefits costs, including restructuring charges in the prior year, partially offset by higher technology and other servicing-related costs.

The effective tax rate in all periods reflects the impact of recurring permanent tax benefits both in relation to the segment’s ongoing funding activities outside the United States, which is allocated to ICNS under our internal tax allocation process, and on varying levels of pretax income. The effective tax rates for the prior year periods also reflects the allocated share of tax benefits related to the resolution of certain prior years’ tax items.

GCS issues a wide range of proprietary corporate and small business cards and provides payment and expense management services globally. In addition, GCS provides commercial financing products.

Non-interest revenues increased for both the three and six month periods, primarily driven by higher discount revenue due to increases in billed business, partially offset by Costco-related revenues in the prior year and increased contra-discount revenue in the current year, driven by higher client incentives due to increased billed business. The increase in non-interest revenues was also driven by higher net card fees for both the three and six month periods, primarily due to growth in the U.S. small business Platinum portfolio.

Net interest income was relatively flat for the three month period and decreased for the six month period, primarily driven by higher interest expense, reflecting an increase in the cost of funds, and Costco cobrand interest income in the prior year, substantially offset by an increase in average Card Member loans and higher net interest yield.

Provisions for losses increased for both the three and six month periods due to strong growth in both Card Member receivables and loans, partially offset by improving credit performance in the commercial financing portfolio.

Marketing, promotion, rewards, Card Member services and other expenses increased for both the three and six month periods, driven by higher Card Member rewards expenses, which increased $119 million and $246 million for the three and six month periods, respectively. The higher Card Member rewards expenses were primarily driven by enhancements to Platinum rewards and higher spending volumes, partially offset by Costco-related expenses in the prior year. Marketing and promotion expenses decreased in the three month period, but increased in the six month period reflecting spending on growth initiatives.

Salaries and employee benefits and other operating expenses increased for both the three and six month periods, primarily driven by the prior-year gain on the sale of the Costco HFS portfolio, partially offset by lower technology-related expenses and the HFS valuation allowance in the prior year.

The effective tax rate was lower for both the three and six months, primarily reflecting the geographic mix of business and the resolution of certain prior years’ tax items in the six month period.

(a) Return on average segment capital is calculated by dividing (i) one-year period segment income ($1.8 billion and $2.0 billion for the twelve months ended June 30, 2017 and 2016, respectively) by (ii) one-year average segment capital ($7.3 billion and $7.2 billion for the twelve months ended June 30, 2017 and 2016, respectively).

(b) Refer to Table 8 footnote (a).

(c) Refer to Table 8 footnote (e).

(d) Adjusted net interest income and net interest yield on Card Member loans are non-GAAP measures. Refer to “Glossary of Selected Terminology” for the definitions of these terms. We believe adjusted net interest income is useful to investors because it is a component of net interest yield on Card Member loans, which provides a measure of profitability of our Card Member loan portfolio.

(e) Refer to Table 9 footnote (b).

(f) For GCP Card Member receivables, delinquency data is tracked based on days past billing status rather than days past due. A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member’s billing statement date. In addition, if we initiate collection procedures on an account prior to the account becoming 90 days past billing, the associated Card Member receivable balance is classified as 90 days past billing. These amounts are shown above as 90+ Days Past Due for presentation purposes.

GMS operates a global payments network that processes and settles proprietary and non-proprietary card transactions. GMS acquires merchants and provides multi-channel marketing programs and capabilities, services and data analytics, leveraging our global closed-loop network. GMS also operates loyalty coalition businesses in certain countries around the world.

Non-interest revenues were relatively flat for both the three and six month periods, primarily due to lower discount revenue driven by Costco cobrand-related revenues in the prior year as well as higher contra-revenues in the current year, offset by billed business growth across other card products and an increase in loyalty coalition revenues.

Marketing, promotion, rewards, Card Member services and other expenses decreased for both the three and six month periods, reflecting higher levels of spending on growth initiatives in the prior year.

Salaries and employee benefits and other operating expenses decreased for both the three and six month periods, primarily driven by a benefit in the current year from a change in the liability related to non-delivery of goods and services by merchants and growth of the OptBlue program, which does not entail merchant acquirer payments.

Corporate & Other

Corporate functions and certain other businesses, including our Prepaid Services business and other operations, are included in Corporate & Other.

Corporate & Other net expense increased to $239 million for the three month period, compared to $229 million in the same period a year ago and decreased to $470 million for the six month period compared to $527 million in the same period a year ago. The decrease for the six month period was primarily driven by prior-year restructuring charges.

Results for both periods included net interest expense related to maintaining the liquidity requirements discussed in “Consolidated Capital Resources and Liquidity – Liquidity Management,” as well as interest expense related to other corporate indebtedness.

CONSOLIDATED CAPITAL RESOURCES AND LIQUIDITY

Our balance sheet management objectives are to maintain:

• A solid and flexible equity capital profile;

• A broad, deep and diverse set of funding sources to finance our assets and meet operating requirements; and

• Liquidity programs that enable us to continuously meet expected future financing obligations and business requirements for at least a twelve-month period, even in the event we are unable to continue to raise new funds under our traditional funding programs during a substantial weakening in economic conditions.

Risk-Weighted Assets		133.5
Average Total Assets to calculate the Tier 1 Leverage Ratio		164.2

(a) Tier 2 capital is the sum of the allowance for loan and receivable losses (limited to 1.25 percent of risk-weighted assets) and $600 million of subordinated notes adjusted for capital held by insurance subsidiaries.

We seek to maintain capital levels and ratios in excess of the minimum regulatory requirements and finance such capital in a cost efficient manner; failure to maintain minimum capital levels could affect our status as a financial holding company and cause the regulatory agencies with oversight of American Express, Centurion Bank and American Express Bank to take actions that could limit our business operations.

Our primary source of equity capital has been the generation of net income. Historically, capital generated through net income and other sources, such as the exercise of stock options by employees, has exceeded the annual growth in our capital requirements. To the extent capital has exceeded business, regulatory and rating agency requirements, we have historically returned excess capital to shareholders through our regular common share dividend and share repurchase program.

47

We maintain certain flexibility to shift capital across our businesses as appropriate. For example, we may infuse additional capital into subsidiaries to maintain capital at targeted levels in consideration of debt ratings and regulatory requirements. These infused amounts can affect the capital profile and liquidity levels at the American Express parent company level. We do not currently intend or foresee a need to shift capital from non-U.S. subsidiaries with permanently reinvested earnings to a U.S. parent company.

The following are definitions for our regulatory risk-based capital ratios and leverage ratio, which are calculated as per standard regulatory guidance:

Risk-Weighted Assets — Assets are weighted for risk according to a formula used by the Federal Reserve to conform to capital adequacy guidelines. On- and off-balance sheet items are weighted for risk, with off-balance sheet items converted to balance sheet equivalents, using risk conversion factors, before being allocated a risk-adjusted weight. Off-balance sheet exposures comprise a minimal part of the total risk-weighted assets.

Common Equity Tier 1 Risk-Based Capital Ratio — Calculated as Common Equity Tier 1 capital (CET1), divided by risk-weighted assets. CET1 is the sum of common shareholders’ equity, adjusted for ineligible goodwill and intangible assets, certain deferred tax assets, as well as certain other comprehensive income items as follows: net unrealized gains/losses on securities and derivatives, and net unrealized pension and other postretirement benefit/losses, all net of tax and subject to transition provisions.

Tier 1 Risk-Based Capital Ratio — Calculated as Tier 1 capital divided by risk-weighted assets. Tier 1 capital is the sum of CET1, our perpetual preferred stock and third-party non-controlling interests in consolidated subsidiaries adjusted for capital held by insurance subsidiaries and deferred tax assets from net operating losses not deducted from CET1. The minimum requirement for the Tier 1 risk-based capital ratio is 1.5 percent higher than the minimum for the CET1 risk-based capital ratio. We have $1.6 billion of preferred shares outstanding to help address a portion of the Tier 1 capital requirements in excess of common equity requirements.

Total Risk-Based Capital Ratio — Calculated as the sum of Tier 1 capital and Tier 2 capital, divided by risk-weighted assets. Tier 2 capital is the sum of the allowance for loan and receivable losses (limited to 1.25 percent of risk-weighted assets), a portion of the unrealized gains on equity securities and $600 million of subordinated notes, adjusted for capital held by insurance subsidiaries.

Tier 1 Leverage Ratio — Calculated by dividing Tier 1 capital by our average total consolidated assets for the most recent quarter.

Supplementary Leverage Ratio — Calculated by dividing Tier 1 capital by total leverage exposure under Basel III. Leverage exposure, which reflects average total consolidated assets with adjustments for Tier 1 capital deductions, average off-balance sheet derivatives exposures, securities purchased under agreements to resell and credit equivalents of undrawn commitments that are both conditionally and unconditionally cancellable.

Fully Phased-in Basel III

Basel III, when fully phased in, will require bank holding companies and their bank subsidiaries to maintain more capital than prior requirements, with a greater emphasis on common equity. The following table presents our estimates for our regulatory risk-based capital ratios and leverage ratios had Basel III been fully phased in as of June 30, 2017. These ratios are calculated using the standardized approach for determining risk-weighted assets. We are currently taking steps toward Basel III advanced approaches implementation in the United States. We believe the presentation of these ratios is helpful to investors by showing the impact of future regulatory capital standards on our capital and leverage ratios.

(a) The Fully Phased-in Basel III Common Equity Tier 1 and Tier 1 risk-based capital ratios, non-GAAP measures, are calculated as Common Equity Tier 1 or Tier 1 capital under Fully Phased-in Basel III rules, as applicable, divided by risk-weighted assets under Fully Phased-in Basel III rules. Refer to Table 21 for a reconciliation of Common Equity Tier 1 and Tier 1 capital under Fully Phased-in Basel III rules to Common Equity Tier 1 and Tier 1 capital under Transitional Basel III rules.

(b) The Fully Phased-in Basel III Tier 1 and supplementary leverage ratios, non-GAAP measures, are calculated by dividing Fully Phased-in Basel III Tier 1 capital by our average total assets and Fully Phased-in total leverage exposure for supplementary leverage ratio purposes under Fully Phased-in Basel III, respectively.

(c) Estimated Fully Phased-in Basel III risk-weighted assets, a non-GAAP measure, reflect our Basel III risk-weighted assets, with all transition provisions fully phased in. This includes incremental risk weighting applied to deferred tax assets and significant investments in unconsolidated financial institutions, as well as exposures to past due accounts, equities and sovereigns.

(d) Estimated Fully Phased-in Basel III Leverage Exposure, a non-GAAP measure, reflects average total consolidated assets with adjustments for Tier 1 capital deductions on a fully phased-in basis, off-balance sheet derivatives, undrawn conditionally and unconditionally cancellable commitments and other off-balance sheet liabilities.

The following table presents a comparison of our CET1 and Tier 1 risk-based capital under Transitional Basel III rules to our estimated CET1 and Tier 1 risk-based capital under Fully Phased-in Basel III rules as of June 30, 2017.

This includes incremental risk weighting applied to deferred tax assets and significant investments in unconsolidated financial institutions, as well as exposures to past due accounts, equities and sovereigns.

Fully Phased-in Basel III Tier 1 Leverage Ratio — Calculated by dividing Fully Phased-in Basel III Tier 1 capital by our average total consolidated assets.

Fully Phased-in Basel III Supplementary Leverage Ratio — Calculated by dividing Fully Phased-in Basel III Tier 1 capital by our Fully Phased-in total leverage exposure for supplementary leverage ratio purposes under Fully Phased-in Basel III.

Share Repurchases and Dividends

We return capital to common shareholders through dividends and share repurchases. The share repurchases reduce common shares outstanding and more than offset the issuance of new shares as part of employee compensation plans.

During the three and six months ended June 30, 2017, we returned $1.1 billion and $2.3 billion, respectively, to our shareholders in the form of common stock dividends ($0.3 billion and $0.6 billion, respectively) and share repurchases ($0.8 billion and $1.7 billion, respectively). We repurchased 11 million common shares at an average price of $79.72 in the second quarter of 2017. These dividend and share repurchase amounts collectively represent approximately 83 percent and 87 percent of total capital generated during the three and six-month periods, respectively.

49

In addition, during the three months ended June 30, 2017, we had $750 million of non-cumulative perpetual preferred shares (the “Series B Preferred Shares”) and $850 million of non-cumulative perpetual preferred shares (the “Series C Preferred Shares”) outstanding. Dividends declared and paid on Series B Preferred Shares during the second quarter of 2017 were $19 million.

On June 28, 2017, we were informed that the Federal Reserve did not object to our capital plan to return capital to shareholders through share repurchases of up to $4.4 billion during the period beginning with the third quarter of 2017 through and including the second quarter of 2018, as well as an increase in our quarterly dividend to $0.35 per share, from $0.32 per share, beginning with the third quarter 2017 dividend declaration, subject to approval by our Board of Directors. The timing and amount of common shares purchased under our authorized capital plan will depend on various factors, including our business plans, financial performance and market conditions. To facilitate repurchases, we may, from time to time, make purchases pursuant to one or more trading plans under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, which allows us to repurchase common shares during periods when we might otherwise be prevented from doing so under applicable law or because of self-imposed trading blackout periods.

Funding Strategy

Our principal funding objective is to maintain broad and well-diversified funding sources to allow us to meet our maturing obligations, cost-effectively finance current and future asset growth in our global businesses as well as to maintain a strong liquidity profile.

Summary of Consolidated Debt

We had the following consolidated debt and customer deposits outstanding as of June 30, 2017 and December 31, 2016:

Table 22: Summary of Consolidated Debt and Customer Deposits

(Billions)	June 30, 2017		December 31, 2016
Short-term borrowings	$	3.4	$	5.6

Total debt		55.3		52.6
Customer deposits		57.7		53.0
Total debt and customer deposits	$	113.0	$	105.6

Management does not currently expect to make any significant changes to our funding programs in order to satisfy Basel III’s Liquidity Coverage Ratio (LCR) standard based upon our current understanding of the requirements, which may be subject to change as we receive additional clarification and implementation guidance from regulators relating to the requirements and as the interpretation of requirements evolves over time.

During the three months ended June 30, 2017, we issued (i) $3.3 billion of asset-backed securities from the American Express Credit Account Master Trust (the Lending Trust) consisting of $1.7 billion of three year Class A Certificates at a fixed rate of 1.77%, and $1.6 billion of two year Class A Certificates at a fixed rate of 1.64%, and (ii) $4.0 billion of senior unsecured notes from American Express Credit Corporation consisting of $1.5 billion of two year notes at a fixed rate of 1.88%, $500 million of two year notes at a  floating rate of  3-month LIBOR plus 33 basis points, and $2.0 billion of ten year notes at a fixed rate of 3.30%.

Our equity capital and funding strategies are designed, among other things, to maintain appropriate and stable unsecured debt ratings from the major credit rating agencies: Moody’s Investor Services (Moody’s), Standard & Poor’s (S&P), Fitch Ratings (Fitch) and Dominion Bond Rating Services (DBRS). Such ratings help support our access to cost-effective unsecured funding as part of our overall funding strategy. Our asset securitization activities are rated separately.

Downgrades in the ratings of our unsecured debt or asset securitization program securities could result in higher funding costs, as well as higher fees related to borrowings under our unused lines of credit. Declines in credit ratings could also reduce our borrowing capacity in the unsecured debt and asset securitization capital markets. We believe our funding mix, including the proportion of U.S. retail deposits insured by the Federal Deposit Insurance Corporation (FDIC), should reduce the impact that credit rating downgrades would have on our funding capacity and costs.

Liquidity Management

We incur liquidity risk that arises in the course of offering our products and services. Our liquidity objective is to maintain access to a diverse set of on- and off-balance sheet liquidity sources. We seek to maintain liquidity sources, even in the event we are unable to raise new funds under our regular funding programs during a substantial weakening in economic conditions, in amounts sufficient to meet our expected future financial obligations and business requirements for liquidity for a period of at least twelve months. Our liquidity risk policy sets out our objectives and approach to managing liquidity risk.

The liquidity risks that we are exposed to could arise from a wide variety of scenarios. Our liquidity management strategy thus includes a number of elements, including, but not limited to:

• Maintaining diversified funding sources (refer to the “Funding Strategy” section for more details);

• Maintaining unencumbered liquid assets and off-balance sheet liquidity sources;

• Projecting cash inflows and outflows under a variety of economic and market scenarios;

• Establishing clear objectives for liquidity risk management, including compliance with regulatory requirements;

• Incorporating liquidity risk management as appropriate into our capital adequacy framework.

The amount and type of liquidity resources we maintain can vary over time, based upon the results of stress scenarios required under the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank) and other various regulatory liquidity requirements, such as the LCR, as well as additional stress scenarios required under our liquidity risk policy.

The investment income we receive on liquidity resources, such as cash, is less than the interest expense on the sources of funding for these balances. The net interest costs to maintain these resources have been substantial. The level of future net interest costs depends on the amount of liquidity resources we maintain and the difference between our cost of funding these amounts and their investment yields.

Securitized Borrowing Capacity

As of June 30, 2017, we maintained our committed, revolving, secured borrowing facility, with a maturity date of July 16, 2018, that gives us the right to sell up to $3.0 billion face amount of eligible AAA notes from the American Express Issuance Trust II (the Charge Trust). On July 14, 2017, we extended the Charge Trust’s $3.0 billion facility by two years to mature on July 15, 2020. We also maintained our committed, revolving, secured borrowing facility, with a maturity date of September 17, 2018, that gives us the right to sell up to $2.0 billion face amount of eligible AAA certificates from the Lending Trust. Both facilities are used in the ordinary course of business to fund seasonal working capital needs, as well as to further enhance our contingent funding resources. As of June 30, 2017, no amounts were drawn on the Charge Trust or Lending Trust facilities.

51

Federal Reserve Discount Window

As insured depository institutions, Centurion Bank and American Express Bank may borrow from the Federal Reserve Bank of San Francisco, subject to the amount of qualifying collateral that they may pledge. The Federal Reserve has indicated that both credit and charge card receivables are a form of qualifying collateral for secured borrowings made through the discount window. Whether specific assets will be considered qualifying collateral and the amount that may be borrowed against the collateral, remain at the discretion of the Federal Reserve.

We had approximately $61.1 billion as of June 30, 2017 in U.S. credit card loans and charge card receivables that could be sold over time through our securitization trusts or pledged in return for secured borrowings to provide further liquidity, subject in each case to applicable market conditions and eligibility criteria.

Committed Bank Credit Facility

In addition to the secured borrowing facilities described earlier in this section, we maintained a committed syndicated bank credit facility as of June 30, 2017 of $3.0 billion, which expires on December 9, 2018. As of June 30, 2017, no amounts were drawn on this facility.

Unused Credit Outstanding

As of June 30, 2017, we had approximately $259 billion of unused credit outstanding as part of established lending product agreements. Total unused credit does not represent potential future cash requirements, as a significant portion of this unused credit will likely not be drawn. Our charge card products generally have no pre-set limit, and therefore are not reflected in unused credit available to Card Members.

Cash Flows

The following table summarizes our cash flow activity for the six months ended June 30:

Table 24: Cash Flows

(Billions)	2017			2016
Total cash provided by (used in):
Operating activities	$	4.3		$	3.2
Investing activities		(4.2	)		12.1
Financing activities		5.0			(4.3	)
Effect of foreign currency exchange rates on cash and cash equivalents		0.1			―
Net increase in cash and cash equivalents	$	5.2		$	11.0

Cash Flows from Operating Activities

Our cash flows from operating activities primarily include net income adjusted for (i) non-cash items included in net income and (ii) changes in the balances of operating assets and liabilities, which can vary significantly in the normal course of business due to the amount and timing of payments.

Net cash provided by operating activities was driven by net income of $2.6 billion and $3.4 billion for the current and prior periods, respectively, adjusted for non-cash items including changes in provisions for losses, depreciation and amortization, deferred taxes, and stock-based compensation. The prior period net income includes gains of $1.2 billion on the sales of the HFS portfolios, which are presented in Net (increase) decrease in Card Member receivables and loans, including held for sale, within cash flows from investing activities. The increase during the periods of comparison was driven primarily by impacts from movements in Other receivables and Other assets as a result of normal business operating activities.

Cash Flows from Investing Activities

Our cash flows from investing activities primarily include changes in Card Member receivables and loans, including Card Member loans and receivables HFS, along with gains on sales related thereto, as well as changes in our available for sale investment securities portfolio.

The decrease in net cash provided by investing activities primarily reflected the sale of the HFS portfolios in the prior period as well as growth in Card Member loans in the current period.

52

Cash Flows from Financing Activities

Our cash flows from financing activities primarily include issuing and repaying debt, changes in customer deposits, issuing and repurchasing our common shares, and paying dividends.

The increase in net cash provided by financing activities primarily resulted from a higher net increase in customer deposits and higher net long-term debt issuances in the current year as well as higher share repurchases in the prior period.

53

OTHER MATTERS

Certain Legislative, Regulatory and Other Developments

We are subject to comprehensive government regulation and supervision in jurisdictions around the world, and the costs of compliance are substantial. In recent years, the financial services industry has been subject to rigorous scrutiny, high regulatory expectations, and a stringent and unpredictable regulatory enforcement environment.

Please see the “Supervision and Regulation” and “Risk Factors” sections of the Annual Report on Form 10-K for the year ended December 31, 2016 (the 2016 Form 10-K) for further information.

Payments Regulation

Legislators and regulators in various countries in which we operate have focused on the operation of card networks, including through antitrust actions, legislation and regulations to change certain practices or pricing of card issuers, merchant acquirers and payment networks, and, in some cases, to establish broad and ongoing regulatory oversight regimes for payment systems.

The European Union, Australia and other jurisdictions have focused on the fees merchants pay to accept cards, including the way bankcard network members collectively set the “interchange” (that is, the fee paid by the bankcard merchant acquirer to the card issuer in “four party” networks like Visa and MasterCard), as well as the rules, contract terms and practices governing merchant card acceptance. Even where we are not directly regulated, regulation of bankcard fees can significantly negatively impact the discount revenue derived from our business, including as a result of downward pressure on our discount rate from decreases in competitor pricing in connection with caps on interchange fees. In some cases, such regulation extends to certain aspects of our business. For example, the EU regulation might apply price caps as well as other regulatory measures in circumstances where three-party networks issue cards with a cobrand partner or through an agent. We have brought a legal challenge and seek a ruling from the EU Court of Justice to clarify the interpretation and validity of that part of the regulation. As a precursor to the Court’s final ruling, an advisory opinion was issued on July 6, 2017 advising the Court that (a) the case should be declared inadmissible and (b) if the Court determines to treat the case as admissible, the law should be considered valid and applicable. The advisory opinion is not binding on the Court and there can be no assurance as to the outcome of our legal challenge. For more information on the European Union payments legislation, our related legal challenge and the Australia payments regulation, as well as the potential impacts on our results of operations and business, please see the “Supervision and Regulation” and “Risk Factors” sections of the 2016 Form 10-K.

Broad regulatory oversight over payment systems can also include, in some cases, requirements for international card networks to localize aspects of their operations, such as processing infrastructure, which could increase our costs and diminish the value of our closed loop. The development and enforcement of payment system regulatory regimes generally continue to grow and may adversely affect our ability to compete effectively and maintain and extend our global network.

Surcharging

In certain countries, such as certain Member States in the European Union and Australia, merchants are permitted by law to surcharge card purchases. While surcharging continues to be actively considered in certain jurisdictions, the benefits to customers have not been apparent in countries that have allowed it, and in some cases regulators are addressing concerns about excessive surcharging by merchants. For example, the Reserve Bank of Australia amended its rules to limit surcharging in Australia to the actual cost of card acceptance paid to the merchant acquirer.

Surcharging, particularly where it disproportionately impacts American Express Card Members, which is known as differential surcharging, as well as other steering practices that are permitted by regulation in some countries, could have a material adverse effect on us if it becomes widespread. As revisions to the Payment Services Directive in the European Union are transposed into national law by each Member State, there may be increased instances of differential surcharging of our cards, customer and merchant confusion as to which transactions may be surcharged and Card Member dissatisfaction. On July 19, 2017, the U.K. indicated it would ban surcharging on consumer cards starting January 2018. In addition, the laws of a number of states in the United States that prohibit surcharging are being challenged in litigation brought by merchant groups.

54

For more information on the potential impacts of surcharging and other actions that could impair the Card Member experience, please see the “Risk Factors” section of the 2016 Form 10-K.

Consumer Financial Products Regulation

In the United States, our marketing and sale of consumer financial products and our compliance with certain federal consumer financial laws are supervised and examined by the Consumer Financial Protection Bureau (CFPB), which has broad rulemaking and enforcement authority over providers of credit, savings and payment services and products and authority to prevent “unfair, deceptive or abusive” acts or practices. In addition, a number of U.S. states have significant consumer credit protection and disclosure laws (in certain cases more stringent than U.S. federal laws). U.S. federal law also regulates abusive debt collection practices, which along with bankruptcy and debtor relief laws, can affect our ability to collect amounts owed to us.

Internal and regulatory reviews to assess compliance with such laws and regulations have resulted in, and are likely to continue to result in, changes to our practices, products and procedures, substantial restitution to our Card Members and increased costs related to regulatory oversight, supervision and examination. Such reviews may also result in additional regulatory actions, including civil money penalties.

These types of reviews will be a continuing focus for the CFPB and regulators more broadly, as well as for the company itself. As an example, federal banking regulators announced they are conducting horizontal reviews of banking sales practices and we are cooperating with regulators in those reviews. Also, in prior years, certain cards issued in Puerto Rico, the U.S. Virgin Islands and other U.S. Territories, largely through our international business, did not uniformly carry the same terms, conditions and features as the cards we offered to Card Members in the continental U.S. We conducted an internal review beginning in 2012, voluntarily provided customer remediation in prior periods and reported this matter to our regulators. We have been cooperating with the CFPB’s review as to whether this discontinued practice complied with applicable laws and regulations. We do not believe this matter will have a material adverse impact on our operations or results.

On July 10, 2017, the CFPB issued a final rule that, among other changes, would prohibit providers of certain consumer financial products and services from using a pre-dispute arbitration agreement to bar consumers from filing or participating in a class action. The rule would apply to agreements entered into on or after March 19, 2018. As a result of the rule, we may face increased class claims and therefore be subject to the complexities and costs associated with class action litigation. Given the inherent uncertainties involved in litigation, and the very large or indeterminate damages sought in some class action matters, there is significant uncertainty as to the ultimate impact of this rule.

For more information on consumer financial products regulation, as well as the potential impacts on our results of operations and business, please see the “Supervision and Regulation” and “Risk Factors” sections of the 2016 Form 10-K.

Antitrust Litigation

The U.S. Department of Justice (DOJ) and certain states’ attorneys general brought an action against us in 2010 alleging that the provisions in our card acceptance agreements with merchants that prohibit merchants from engaging in various actions to discriminate against our card products violate the U.S. antitrust laws. The trial court ruled that the challenged provisions violate U.S. antitrust laws and issued an injunction. Following our appeal of this judgment, the Court of Appeals for the Second Circuit reversed the trial court decision and directed the trial court to enter a judgment for American Express, which occurred on January 25, 2017. We continue to vigorously defend similar antitrust claims initiated by merchants in other court and arbitration proceedings. See the “Legal Proceedings” section in our 2016 Form 10-K for descriptions of the DOJ and related cases. It is possible that significantly increased merchant steering or other actions impairing the Card Member experience, or the resolution of one or any combination of these merchant claims for damages, could have a material adverse effect on our business. For more information on the potential impacts of an adverse decision in the merchant litigations on our business, please see the “Risk Factors” section of the 2016 Form 10-K.

Recently Issued Accounting Standards

Refer to the Recently Issued Accounting Standards section of Note 1 to the “Consolidated Financial Statements.”

Glossary of Selected Terminology

Adjusted net interest income — A non-GAAP measure that represents net interest income attributable to our Card Member loans and loans HFS (which includes, on a GAAP basis, interest that is deemed uncollectible), excluding the impact of interest expense and interest income not attributable to our Card Member loans. We believe adjusted net interest income is useful to investors because it is a component of net interest yield on Card Member loans.

Asset securitizations — Asset securitization involves the transfer and sale of loans or receivables to a special-purpose entity created for the securitization activity, typically a trust. The trust, in turn, issues securities, commonly referred to as asset-backed securities that are secured by the transferred loans and receivables. The trust uses the proceeds from the sale of such securities to pay the purchase price for the underlying loans or receivables. The loans and receivables of our Lending Trust and Charge Trust securitized are reported as assets and the securities issued by the Trusts are reported as liabilities on our Consolidated Balance Sheets.

Average discount rate — This calculation is generally designed to reflect pricing at merchants accepting general-purpose American Express cards. It represents the percentage of billed business (generated from both proprietary and GNS Card Member spending) retained by us from merchants we acquire, or for merchants acquired by a third party on our behalf, net of amounts retained by such third party.

Basic cards-in-force — Proprietary basic consumer cards-in-force includes basic cards issued to the primary account owner, (i.e., not including additional supplemental cards issued on accounts). Proprietary basic small business and corporate cards-in-force includes both basic and supplemental cards issued. Non-proprietary basic cards-in-force includes cards that are issued and outstanding under network partnership agreements, except for supplemental cards and retail cobrand Card Member accounts which have had no out-of-store spending activity during the prior twelve-month period.

Billed business — Includes activities (including cash advances) related to proprietary cards, cards issued under network partnership agreements (non-proprietary billed business), corporate payment services and certain insurance fees charged on proprietary cards. In-store spending activity within retail cobrand portfolios in GNS, from which we earn no revenue, is not included in non-proprietary billed business. Card billed business is included in the United States or outside the United States based on where the issuer is located.

Capital ratios — Represents the minimum standards established by the regulatory agencies as a measure to determine whether the regulated entity has sufficient capital to absorb on- and off-balance sheet losses beyond current loss accrual estimates. Refer to the Capital Strategy section under “Consolidated Capital Resources and Liquidity” for further related definitions under Transitional Basel III and Fully Phased-in Basel III.

Card Member — The individual holder of an issued American Express-branded charge, credit and certain prepaid cards.

Card Member loans — Represents the outstanding amount due from Card Members for charges made on their American Express credit cards, as well as any interest charges and card-related fees. Card Member loans also include revolving balances on certain American Express charge card products.

Card Member loans and receivables HFS — Beginning as of December 1, 2015 and continuing until the sales were completed, represents Card Member loans and receivables related to our cobrand partnerships with Costco in the United States and JetBlue. The JetBlue and Costco portfolio sales were completed on March 18 and June 17, 2016, respectively.

Card Member receivables — Represents the outstanding amount due from Card Members for charges made on their American Express charge cards, as well as any card-related fees.

Charge cards — Represents cards that generally carry no pre-set spending limits and are primarily designed as a method of payment and not as a means of financing purchases. Charge Card Members generally must pay the full amount billed each month. No finance charges are assessed on charge cards. Each charge card transaction is authorized based on its likely economics reflecting a Card Member’s most recent credit information and spend patterns. Some charge card accounts have additional “Pay Over Time” feature(s) that allow revolving of certain balances.

56

Cobrand cards — Cards issued under cobrand agreements with selected commercial firms. Pursuant to the cobrand agreements, we make payments to our cobrand partners, which can be significant, based primarily on the amount of Card Member spending and corresponding rewards earned on such spending and, under certain arrangements, on the number of accounts acquired and retained. In some cases, the partner is liable for providing rewards to the Card Member under the cobrand partner’s own loyalty program.

Credit cards — Represents cards that have a range of revolving payment terms, grace periods, and rate and fee structures.

Discount revenue — Represents revenue earned from fees generally charged to merchants who have entered into a card acceptance agreement. The discount fee generally is deducted from our payment for Card Member purchases. Discount revenue is reduced by incentive payments made to merchants, payments to third-party card issuing partners, cash-back reward costs and statement credits, corporate incentive payments and other similar items.

Interest expense — Includes interest incurred primarily to fund Card Member loans and receivables, general corporate purposes and liquidity needs, and is recognized as incurred. Interest expense is divided principally into two categories: (i) deposits, which primarily relates to interest expense on deposits taken from customers and institutions, and (ii) debt, which primarily relates to interest expense on our long-term financing and short-term borrowings, (e.g., commercial paper, federal funds purchased, bank overdrafts and other short-term borrowings), as well as the realized impact of derivatives hedging interest rate risk on our long-term debt.

Interest income — Includes (i) interest on loans, (ii) interest and dividends on investment securities and (iii) interest income on deposits with banks and other.

Interest on loans — Assessed using the average daily balance method for Card Member loans and loans HFS. Unless the loan is classified as non-accrual, interest is recognized based upon the principal amount outstanding in accordance with the terms of the applicable account agreement until the outstanding balance is paid or written off.

Interest and dividends on investment securities — Primarily relates to our performing fixed-income securities. Interest income is recognized as earned using the effective interest method, which adjusts the yield for security premiums and discounts, fees and other payments, so a constant rate of return is recognized on the outstanding balance of the related investment security throughout its term. Amounts are recognized until securities are in default or when it is likely that future interest payments will not be made as scheduled.

Interest income on deposits with banks and other — Recognized as earned, and primarily relates to the placement of cash in excess of near-term funding requirements in interest-bearing time deposits, overnight sweep accounts, and other interest-bearing demand and call accounts.

Liquidity Coverage Ratio —Represents the minimum standards established by the regulatory agencies as a measure to determine whether the regulated entity has sufficient liquidity to meet liquidity needs in periods of financial and economic stress.

Merchant acquisition — Represents our process of entering into agreements with merchants to accept American Express-branded cards.

Net card fees — Represents the card membership fees earned during the period. These fees are recognized as revenue over the covered card membership period (typically one year), net of the provision for projected refunds for Card Membership cancellation and deferred acquisition costs.

Net interest yield on Card Member loans —A non-GAAP measure that is computed by dividing adjusted net interest income by average loans, computed on an annualized basis. Reserves and net write-offs related to uncollectible interest are recorded through provisions for losses, and are thus not included in the net interest yield calculation. We believe net interest yield on Card Member loans is useful to investors because it provides a measure of profitability of our Card Member loan portfolio.

Net loss ratio — Represents the ratio of GCP charge card write-offs, consisting of principal (resulting from authorized transactions) and fee components, less recoveries, on Card Member receivables expressed as a percentage of gross amounts billed to corporate Card Members.

Net write-off rate — principal only — Represents the amount of proprietary consumer or small business  Card Member loans or receivables written off, consisting of principal (resulting from authorized transactions), less recoveries, as a percentage of the average loan or receivables balance during the period.

Net write-off rate — principal, interest and fees — Includes, in the calculation of the net write-off rate, amounts for interest and fees in addition to principal for Card Member loans and fees in addition to principal for Card Member receivables.

57

Operating expenses — Represents salaries and employee benefits, professional services, occupancy and equipment, and other expenses.

Return on average equity — Calculated by dividing one-year period net income by one-year average total shareholders’ equity.

Return on average segment capital — Calculated by dividing one-year period segment income by one-year average segment capital.

Segment capital — Represents the capital allocated to a segment based upon specific business operational needs, risk measures, and regulatory capital requirements.

Total cards-in-force — Represents the total number of charge and credit cards that are issued and outstanding and accepted on our network. Non-proprietary cards-in-force includes all charge and credit cards that are issued and outstanding under network partnership agreements, except for retail cobrand Card Member accounts which have no out-of-store spending activity during the prior twelve-month period.

58

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk to earnings or asset and liability values resulting from movements in market prices. Our market risk exposures include (i) interest rate risk due to changes in the relationship between the interest rates on our assets (such as loans, receivables and investment securities) and the interest rates on our liabilities (such as debt and deposits); and (ii) foreign exchange risk related to transactions, funding, investments and earnings in currencies other than the U.S. dollar. There were no material changes in these market risks since December 31, 2016.

ITEM 4. CONTROLS AND PROCEDURES

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)) as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are effective and designed to ensure that the information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the requisite time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Cautionary Note Regarding Forward-looking Statements

This report includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, which are subject to risks and uncertainties. The forward-looking statements, which address our expected business and financial performance, among other matters, contain words such as “believe,” “expect,” “estimate,” “anticipate,” “intend,” “plan,” “aim,” “will,” “may,” “should,” “could,” “would,” “likely,” and similar expressions. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. We undertake no obligation to update or revise any forward-looking statements. Factors that could cause actual results to differ materially from these forward-looking statements, include, but are not limited to, the following:

• our ability to grow in the future, which will depend in part on the following: revenues growing consistently with current expectations, which could be impacted by, among other things, the factors identified in the subsequent bullet; the level of spend in bonus categories on rewards-based and/or cash-back cards and redemptions of Card Member rewards and offers; the impact of any future contingencies, including, but not limited to, litigation-related settlements, judgments or expenses, the imposition of fines or civil money penalties, an increase in Card Member reimbursements, restructurings, impairments and changes in reserves; write-downs of deferred tax assets as a result of tax law or other changes; credit performance remaining consistent with current expectations; the ability to continue to realize benefits from restructuring actions and operating leverage at levels consistent with current expectations; the amount we spend on Card Member engagement and our ability to drive growth from such investments; changes in interest rates beyond current expectations (including the impact of hedge ineffectiveness and deposit rate increases); the impact of regulation and litigation, which could affect the profitability of our business activities, limit our ability to pursue business opportunities, require changes to business practices or alter our relationships with partners, merchants and Card Members; our tax rate remaining in line with current expectations, which could be impacted by, among other things, our geographic mix of income being weighted more to higher tax jurisdictions than expected, changes in tax laws and regulation and unfavorable tax audits and other unanticipated tax items; the impact of accounting changes and reclassifications; and our ability to continue executing the share repurchase program;

59

• our ability to grow revenues net of interest expense, which could be impacted by, among other things, weakening economic conditions in the United States or internationally, a decline in consumer confidence impacting the willingness and ability of Card Members to sustain and grow spending, continued growth of Card Member loans, a greater erosion of the average discount rate than expected, the strengthening of the U.S. dollar, a greater impact on discount revenue from cash back and cobrand partner and client incentive payments, more cautious spending by large and global corporate Card Members, the willingness of Card Members to pay higher card fees, and lower spending on new cards acquired than estimated; and will depend on factors such as our success in addressing competitive pressures and implementing our strategies and business initiatives, including growing profitable spending from existing  and new Card Members, increasing penetration among middle market and small business clients, expanding our international footprint and increasing merchant acceptance;

• changes in the substantial and increasing worldwide competition in the payments industry, including competitive pressure that may impact the prices we charge merchants that accept our cards, competition for cobrand relationships and the success of marketing, promotion or rewards programs;

• rewards expense and cost of Card Member services growing inconsistently from expectations, which will depend in part on Card Member behavior as it relates to their spending patterns and actual usage and redemption of rewards, as well as the degree of interest of Card Members in the value proposition we offer; increasing competition, which could result in greater rewards offerings; our ability to enhance card products and services to make them attractive to Card Members; and the amount we spend on the promotion of enhanced services and rewards categories and the success of such promotion;

• the actual amount to be spent on marketing and promotion, which will be based in part on management’s assessment of competitive opportunities; overall business performance and changes in macroeconomic conditions; the actual amount of advertising and Card Member acquisition costs; competitive pressures that may require additional expenditures; our ability to continue to shift Card Member acquisition to digital channels; contractual obligations with business partners and other fixed costs and prior commitments; management’s ability to identify attractive investment opportunities and make such investments, which could be impacted by business, regulatory or legal complexities; and our ability to realize efficiencies, optimize investment spending and control expenses to fund such spending;

• our ability to reduce our overall cost base, which will depend in part on the timing and financial impact of reengineering plans, which could be impacted by factors such as our inability to mitigate the operational and other risks posed by potential staff reductions, our inability to develop and implement technology resources to realize cost savings and underestimating hiring and other employee needs; our ability to reduce annual operating expenses, which could be impacted by, among other things, the factors identified below; our ability to optimize marketing and promotion expenses, which could be impacted by the factors identified in the preceding bullet;

• the ability to reduce annual operating expenses, which could be impacted by the need to increase significant categories of operating expenses, such as consulting or professional fees, including as a result of increased litigation, compliance or regulatory-related costs, or fraud costs; our ability to develop, implement and achieve substantial benefits from reengineering plans; higher than expected employee levels; the impact of changes in foreign currency exchange rates on costs; the payment of civil money penalties, disgorgement, restitution, non-income tax assessments and litigation-related settlements; impairments of goodwill or other assets; management’s decision to increase or decrease spending in such areas as technology, business and product development and sales forces; greater than expected inflation; our ability to balance expense control and investments in the business; the impact of accounting changes and reclassifications; and the level of M&A activity and related expenses;

• our delinquency and write-off rates and growth of provisions for losses being higher than current expectations, which will depend in part on changes in the level of loan balances and delinquencies, mix of loan balances, loans and receivables related to new Card Members and other borrowers performing as expected, credit performance of new and enhanced lending products, unemployment rates, the volume of bankruptcies and recoveries of previously written-off loans;

• our ability to execute against our lending strategy to grow loans, which may be affected by increasing competition, brand perceptions and reputation, our ability to manage risk in a growing Card Member loan portfolio, and the behavior of Card Members and their actual spending and borrowing patterns, which in turn may be driven by our ability to issue new and enhanced card products, offer attractive non-card lending products, capture a greater share of existing Card Members’ spending and borrowings, reduce Card Member attrition and attract new customers;

• the possibility that we will not execute on our plans to significantly increase merchant coverage, which will depend in part on the success of OptBlue merchant acquirers in signing merchants to accept American Express, which could be impacted by the pricing set by the merchant acquirers, the value proposition offered to small merchants and the efforts of OptBlue merchant acquirers to sign merchants for American Express acceptance, as well as the awareness and willingness of Card Members to use American Express cards at small merchants and of those merchants to accept American Express cards;

• changes affecting our ability or desire to return capital to shareholders through dividends and share repurchases, which will depend on factors such as approval of our capital plans by our primary regulators, the amount we spend on acquisitions of companies and our results of operations and capital needs and economic environment in any given period;

• deposit rates increasing faster or slower than current expectations due to changes in our funding mix, market pressures, regulatory constraints or changes in benchmark interest rates, which could affect net interest yield and our funding costs;

• net interest yield on Card Member loans remaining consistent with current expectations, which will be influenced by, among other things, interest rates, changes in consumer behavior that affect loan balances, such as paydown rates, Card Member acquisition strategy, product mix, cost of funds, credit actions, including line size and other adjustments to credit availability, potential pricing changes and deposit rates, which could be impacted by, among other things, the factors identified in the preceding bullet;

• changes in global economic and business conditions, consumer and business spending, the availability and cost of capital, unemployment rates, geopolitical conditions (including potential impacts resulting from the U.S. Administration and the proposed exit of the United Kingdom from the European Union), foreign currency rates and interest rates, all of which may significantly affect demand for and spending on American Express cards, delinquency rates, loan balances and other aspects of our business and results of operations;

• changes in capital and credit market conditions, including sovereign creditworthiness, which may significantly affect our ability to meet our liquidity needs, expectations regarding capital and liquidity ratios, access to capital and cost of capital, including changes in interest rates; changes in market conditions affecting the valuation of our assets; or any reduction in our credit ratings or those of our subsidiaries, which could materially increase the cost and other terms of our funding, restrict our access to the capital markets or result in contingent payments under contracts;

• legal and regulatory developments, including with regard to broad payment system regulatory regimes, actions by the CFPB and other regulators and the stricter regulation of financial institutions, which could require us to make fundamental changes to many of our business practices, including our ability to continue certain GNS and other partnerships; exert further pressure on the average discount rate and GNS volumes; result in increased costs related to regulatory oversight, litigation-related settlements, judgments or expenses, restitution to Card Members or the imposition of fines or civil money penalties; materially affect our capital or liquidity requirements, results of operations or ability to pay dividends or repurchase our stock; or result in harm to the American Express brand;

• potential actions by the FDIC and credit rating agencies applicable to securitization trusts, which could impact our asset securitization program;

• potential changes to the taxation of our businesses, the allowance of deductions for significant expenses, or the incidence of consumption taxes on our transactions, products and services;

• changes in the financial condition and creditworthiness of our business partners, such as bankruptcies, restructurings or consolidations, including merchants that represent a significant portion of our business, such as the airline industry, or our partners in GNS or financial institutions that we rely on for routine funding and liquidity, which could materially affect our financial condition or results of operations; and

• factors beyond our control such as fire, power loss, disruptions in telecommunications, severe weather conditions, natural disasters, health pandemics, terrorism, cyberattacks or fraud, all of which could significantly affect demand for and spending on American Express cards, delinquency rates, loan balances and other aspects of our business and results of operations or disrupt our global network systems and ability to process transactions.

A further description of these uncertainties and other risks can be found in the 2016 Form 10-K and our other reports filed with the Securities and Exchange Commission.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the ordinary course of business, we are subject to various pending and potential legal actions, arbitration proceedings, claims, investigations, examinations, information gathering requests, subpoenas, inquiries and matters relating to compliance with laws and regulations (collectively, legal proceedings).

We do not believe we are a party to, nor are any of our properties the subject of, any legal proceeding that would have a material adverse effect on our consolidated financial condition or liquidity. However, in light of the uncertainties involved in such matters, including the fact that some pending legal proceedings are at preliminary stages or seek an indeterminate amount of damages, it is possible that the outcome of legal proceedings, including the possible resolution of merchant claims, could have a material impact on our results of operations. In addition, it is possible that significantly increased merchant steering or other actions impairing the Card Member experience could have a material adverse effect on our business. Certain legal proceedings involving us or our subsidiaries are described in this section and others, for which there have been no subsequent material developments since the filing of our 2016 Form 10-K, are described in such report. For additional information, see Note 8 to our “Consolidated Financial Statements.”

In 2010, the DOJ, along with Attorneys General from Arizona, Connecticut, Hawaii (Hawaii has since withdrawn its claim), Idaho, Illinois, Iowa, Maryland, Michigan, Missouri, Montana, Nebraska, New Hampshire, Ohio, Rhode Island, Tennessee, Texas, Utah and Vermont filed a complaint in the U.S. District Court for the Eastern District of New York against us, MasterCard International Incorporated and Visa, Inc., alleging a violation of Section 1 of the Sherman Antitrust Act (the DOJ case). The complaint included allegations that provisions in our merchant agreements prohibiting merchants from steering a customer to use another network’s card or another type of general-purpose card (“anti-steering” and “non-discrimination” contractual provisions) violate the antitrust laws. The complaint sought a judgment permanently enjoining us from enforcing our non-discrimination contractual provisions. The complaint did not seek monetary damages.

Following a non-jury trial in the DOJ case, the trial court found that the challenged provisions were anticompetitive and on April 30, 2015, the court issued a final judgment entering a permanent injunction. Following our appeal of this judgment, on September 26, 2016, the Court of Appeals for the Second Circuit reversed the trial court decision and directed the trial court to enter a judgment for American Express. Following denial of rehearing en banc by the Court of Appeals for the Second Circuit, the trial court entered judgment for American Express on January 25, 2017. On June 2, 2017, the DOJ announced it would not petition the U.S. Supreme Court to review the Second Circuit’s decision in favor of American Express. At the same time, 11 of the 17 states that are party to the case filed a petition with the Supreme Court seeking such a review.

ITEM 1A. RISK FACTORS

For a discussion of our risk factors, see Part I, Item 1A. “Risk Factors” of the 2016 Form 10-K. There are no material changes from the risk factors set forth in the 2016 Form 10-K. However, the risks and uncertainties that we face are not limited to those set forth in the 2016 Form 10-K. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business and the trading price of our securities.

Our incentive compensation plans provide that the value of the shares delivered or attested to, or withheld, be based on the price of our common stock on the date the relevant transaction occurs.

(c) Share purchases under publicly announced programs are made pursuant to open market purchases or privately negotiated transactions (including employee benefit plans) as market conditions warrant and at prices we deem appropriate.

ITEM 5. OTHER INFORMATION

Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012, which added Section 13(r) to the Exchange Act, an issuer is required to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with individuals or entities designated pursuant to certain Executive Orders. Disclosure is generally required even where the activities, transactions or dealings were conducted outside the United States by non-U.S. affiliates in compliance with applicable law, and whether or not the activities are sanctionable under U.S. law.

American Express Global Business Travel (GBT) and certain entities that may be considered affiliates of GBT have informed us that during the second quarter of 2017 approximately 95 visas were obtained from Iranian embassies and consulates around the world in connection with certain travel arrangements on behalf of clients. GBT had negligible gross revenues and net profits attributable to these transactions and intends to continue to engage in these activities on a limited basis so long as such activities are permitted under U.S. law.

(a) Included in interest expense is interest expense related to the Card Member lending activities, international banking operations, and charge card and other activities in the Consolidated Statements of Income. Interest expense does not include interest on liabilities recorded under GAAP governing accounting for uncertainty in income taxes. The Company’s policy is to classify such interest in income tax provision in the Consolidated Statements of Income.

(b) For purposes of the “earnings” computation, “other adjustments” include adding the amortization of capitalized interest, the net loss of affiliates accounted for under the equity method whose debt is not guaranteed by the Company, the non-controlling interest in the earnings of majority-owned subsidiaries with fixed charges, and the interest component of rental expense, and subtracting undistributed net income of affiliates accounted for under the equity method.

(c) For purposes of the “fixed charges” computation, “other adjustments” include capitalized interest costs and the interest component of rental expense.

Basis of Presentation

1. Basis of Presentation

The Company

American Express Company (the Company) is a global services company that provides customers with access to products, insights and experiences that enrich lives and build business success. The Company’s principal products and services are charge and credit payment card products and travel-related services offered to consumers and businesses around the world. Business travel-related services are offered through the non-consolidated joint venture, American Express Global Business Travel (the GBT JV). The Company’s various products and services are sold globally to diverse customer groups, including consumers, small businesses, mid-sized companies and large corporations. These products and services are sold through various channels, including direct mail, online applications, in-house and third-party sales forces and direct response advertising.

The accompanying Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (the Annual Report). If not materially different, certain footnote disclosures included therein have been omitted from this Quarterly Report on Form 10-Q.

The interim consolidated financial information in this report has not been audited. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period consolidated financial information, have been made. Results of operations reported for interim periods are not necessarily indicative of results for the entire year.

The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. These accounting estimates reflect the best judgment of management, but actual results could differ.

Certain reclassifications of prior period amounts have been made to conform to the current period presentation.

Recently Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (FASB) issued new accounting guidance on revenue recognition. The accounting standard establishes the principles to apply to determine the amount and timing of revenue recognition, specifying the accounting for certain costs related to revenue, and requiring additional disclosures about the nature, amount, timing and uncertainty of revenues and related cash flows. The guidance, as amended, supersedes most of the current revenue recognition requirements, and is effective January 1, 2018.

Upon adoption of the new revenue recognition guidance, the Company anticipates using the full retrospective method, which applies the new standard to each prior reporting period presented. The Company has been working on the implementation of the standard since its issuance in 2014 and has made significant progress in evaluating the potential impact on its Consolidated Financial Statements. There will be changes to the recognition timing and classification of revenues and expenses, including potential changes to the presentation of certain credit and charge card related costs that are currently netted against discount revenue. The Company does not expect a significant impact to pretax income upon adoption. The Company is also in the process of implementing changes to its accounting policies, business processes, systems and internal controls to support the recognition, measurement and disclosure requirements under the new standard.

In January 2016, the FASB issued new accounting guidance on the recognition and measurement of financial assets and financial liabilities. The guidance, which is effective January 1, 2018, makes targeted changes to current GAAP, specifically to the classification and measurement of equity securities, and to certain disclosure requirements associated with the fair value of financial instruments. In the ordinary course of business, the Company makes investments in non-public companies currently recognized under cost method accounting. Under the new guidance, these investments will be prospectively adjusted for observable price changes upon identification of identical or similar transactions of the same issuer. The Company continues to evaluate the impact this guidance will have on its financial position, results of operations and cash flows, as well as the impact the standard will have on its accounting policies, business processes, systems and internal controls.

In February 2016, the FASB issued new accounting guidance on leases. The guidance, which is effective January 1, 2019, with early adoption permitted, requires virtually all leases to be recognized on the Consolidated Balance Sheets. The Company currently anticipates adopting the standard effective January 1, 2019, using the modified retrospective approach, which requires recording existing operating leases on the Consolidated Balance Sheets upon adoption and in the comparative period. The Company is in the process of upgrading its existing lease administration software for new lease accounting functionality, business processes and internal controls in preparation for the implementation. Specifically, the Company is currently reviewing its lease portfolio and is evaluating and interpreting the requirements under the guidance, including the available accounting policy elections, in order to determine the impacts to the Company’s financial position, results of operations and cash flows upon adoption.

In June 2016, the FASB issued new accounting guidance for recognition of credit losses on financial instruments, which is effective January 1, 2020, with early adoption permitted on January 1, 2019. The guidance introduces a new credit reserving model known as the Current Expected Credit Loss (CECL) model, which is based on expected losses, and differs significantly from the incurred loss approach used today. The CECL model requires measurement of expected credit losses not only based on historical experience and current conditions, but also by including reasonable and supportable forecasts incorporating forward-looking information. The guidance requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption. The Company does not intend to adopt the new standard early and is currently evaluating the impact the new guidance will have on its financial position, results of operations and cash flows; however, it is expected that the CECL model will alter the assumptions used in estimating credit losses on Card Member loans and receivables, among other financial instruments (e.g., investments in available-for-sale debt securities), and may result in material increases to the Company’s credit reserves as the new guidance involves earlier recognition of expected losses for the life of the assets. The Company has established an enterprise-wide, cross-discipline governance structure to implement the new standard. The Company is currently identifying key interpretive issues, and is evaluating existing credit loss forecasting models and processes in relation to the new guidance to determine what modifications may be required.

2. Business Events

During the fourth quarter of 2015, it was determined the Company would sell the Card Member loans and receivables related to its cobrand partnerships with JetBlue Airways Corporation (JetBlue) and Costco Wholesale Corporation (Costco) in the United States (the HFS portfolios). As a result, the HFS portfolios were presented as held for sale (HFS) on the Consolidated Balance Sheets within Card Member loans and receivables HFS as of December 31, 2015.

During the first half of 2016, the Company completed the sales of substantially all of its outstanding Card Member loans and receivables HFS and recognized gains, as an expense reduction, in Other expenses, of $127 million and $1.1 billion during the three months ended March 31, 2016 and June 30, 2016, respectively. The impact of the sales, including the recognition of the proceeds received and the reclassification of the retained Card Member loans and receivables, is reported within the investing section of the Consolidated Statements of Cash Flows as a net decrease in Card Member receivables and loans, including HFS.

From the point of classification as HFS through the sale completion dates, the Company continued to recognize discount revenue, interest income, other revenues and expenses related to the HFS portfolios in the respective line items on the Consolidated Statements of Income, with changes in the valuation of the HFS portfolios recognized in Other expenses.

• For Global Corporate Payments (GCP) Card Member loans and receivables in Global Commercial Services (GCS), delinquency data is tracked based on days past billing status rather than days past due. A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member’s billing statement date. In addition, if the Company initiates collection procedures on an account prior to the account becoming 90 days past billing, the associated Card Member loan and receivable balance is classified as 90 days past billing. These amounts are shown above as 90+ Days Past Due for presentation purposes. See also (b).
• Delinquency data for periods other than 90 days past billing is not available due to system constraints. Therefore, such data has not been utilized for risk management purposes. The balances that are current to 89 days past due can be derived as the difference between the Total and the 90+ Days Past Due balances.

The Company presents a net write-off rate based on principal losses only (i.e., excluding interest and/or fees) to be consistent with industry convention. In addition, because the Company considers uncollectible interest and/or fees in estimating its reserves for credit losses, a net write-off rate including principal, interest and/or fees is also presented.

Impaired Card Member Loans and Receivables

Impaired Card Member loans and receivables are individual larger balance or homogeneous pools of smaller balance loans and receivables for which it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the Card Member agreement. In certain cases, these Card Member loans and receivables are included in one of the Company’s various Troubled Debt Restructuring (TDR)modification programs.

The following tables provide additional information with respect to the Company’s impaired Card Member loans and receivables. Impaired Card Member receivables are not significant for International Consumer and Network Services (ICNS) as of June 30, 2017 and December 31, 2016; therefore, this segment’s receivables are not included in the following tables.

Investment Securities

5. Investment Securities

Investment securities principally include debt securities the Company classifies as available-for-sale and carries at fair value on the Consolidated Balance Sheets, with unrealized gains and losses recorded in accumulated other comprehensive income (loss) (AOCI), net of income taxes. Realized gains and losses are recognized upon disposition of the securities using the specific identification method.

The following is a summary of investment securities as of June 30, 2017 and December 31, 2016:

Total as of December 31, 2016	37	$	451	$	(19)	6	$	32	$	(2)	43	$	483	$	(21)

The gross unrealized losses are attributed to overall wider credit spreads for specific issuers, adverse changes in market benchmark interest rates, or a combination thereof, all compared to those prevailing when the investment securities were acquired.

Overall, for the investment securities in gross unrealized loss positions, (i) the Company does not intend to sell the investment securities, (ii) it is more likely than not that the Company will not be required to sell the investment securities before recovery of the unrealized losses, and (iii) the Company expects that the contractual principal and interest will be received on the investment securities. As a result, the Company recognized no other-than-temporary impairment during the periods presented.

Contractual maturities for investment securities with stated maturities as of June 30, 2017were as follows:

				Estimated
(Millions)		Cost		Fair Value
Due within 1 year	$	623	$	623
Due after 1 year but within 5 years		979		984
Due after 5 years but within 10 years		294		298
Due after 10 years		1,390		1,406
Total	$	3,286	$	3,311

The expected payments on state and municipal obligations and mortgage-backed securities may not coincide with their contractual maturities because the issuers have the right to call or prepay certain obligations.

Asset Securitizations

6. Asset Securitizations

The Company periodically securitizes Card Member loans and receivables arising from its card businessesthrough the transfer of those assets to securitization trusts. The trusts then issue debt securities collateralized by the transferred assets to third-party investors.

The following table provides information on the restricted cash held by the American Express Credit Account Master Trust (the Lending Trust) and the American Express Issuance Trust II (the Charge Trust, collectively the Trusts) as of June 30, 2017 and December 31, 2016, included in Other assets on the Consolidated Balance Sheets:

(Millions)	2017		2016
Lending Trust	$	53	$	35
Charge Trust		2		3
Total	$	55	$	38

These amounts relate to collections of Card Member loans and receivables to be used by the Trusts to fund future expenses and obligations, including interest on debt securities, credit losses and upcoming debt maturities.

American Express Travel Related Services Company, Inc. (TRS), in its role as servicer of the Trusts, has the power to direct the activities that most significantly impact the Trusts’ economic performance, which are the collection of the underlying Card Member loans and receivables. In addition, TRS directly and indirectly (through its consolidated subsidiaries) holds all of the variable interests in both Trusts, with the exception of the debt securities issued to third-party investors.  As of June 30, 2017, TRS’ direct and indirect ownership of variable interests was $9.8 billion for the Lending Trust and $6.5 billion for the Charge Trust. These variable interests held by TRS provide it with the right to receive benefits and the obligation to absorb losses, which could be significant to both the Lending Trust and the Charge Trust. Based on these considerations, TRS is the primary beneficiary of both Trusts and therefore consolidates both Trusts.

Under the respective terms of the Lending Trust and the Charge Trust agreements, the occurrence of certain triggering events associated with the performance of the assets of each Trust could result in payment of trust expenses, establishment of reserve funds, or, in a worst-case scenario, early amortization of debt securities. During the six months endedJune 30, 2017 and the year ended December 31, 2016, no such triggering events occurred.

Contingencies

8. Contingencies

In the ordinary course of business, the Company and its subsidiaries are subject to various pending and potential legal actions, arbitration proceedings, claims, investigations, examinations, information gathering requests, subpoenas, inquiries and matters relating to compliance with laws and regulations (collectively, legal proceedings). The Company discloses its material legal proceedings under Part II, Item 1. “Legal Proceedings” in this Quarterly Report on Form 10-Q and Part I, Item 3. “Legal Proceedings” in the Annual Report.

In addition to the matters disclosed under “Legal Proceedings,” the Company is being challenged in a number of countries regarding its application of value-added taxes (VAT) to certain of its international transactions, which are in various stages of audit, or are being contested in legal actions (collectively, VAT matters). While the Company believes it has complied with all applicable tax laws, rules and regulations in the relevant jurisdictions, the tax authorities may determine that the Company owes additional VAT. In certain jurisdictions where the Company is contesting the assessments, it was required to pay the VAT assessments prior to contesting.

The Company’s legal proceedings range from cases brought by a single plaintiff to class actions with millions of putative class members. These legal proceedings involve various lines of business of the Company and a variety of claims (including, but not limited to, common law tort, contract, application of tax laws, antitrust and consumer protection claims), some of which present novel factual allegations and/or unique legal theories. While some matters pending against the Company specify the damages claimed by the plaintiff or class, many seek an unspecified amount of damages or are at very early stages of the legal process. Even when the amount of damages claimed against the Company are stated, the claimed amount may be exaggerated and/or unsupported. As a result, some matters have not yet progressed sufficiently through discovery and/or development of important factual information and legal issues to enable the Company to estimate an amount of loss or a range of possible loss, while other matters have progressed sufficiently such that the Company is able to estimate an amount of loss or a range of possible loss.

The Company has recorded reserves for certain of its outstanding legal proceedings. A reserve is recorded when it is both (a) probable that a loss has occurred and (b) the amount of loss can be reasonably estimated. There may be instances in which an exposure to loss exceeds the recorded reserve. The Company evaluates, on a quarterly basis, developments in legal proceedings that could cause an increase or decrease in the amount of the reserve that has been previously recorded, or a revision to the disclosed estimated range of possible losses, as applicable.

For those disclosed material legal proceedings and VAT matters where a loss is reasonably possible in future periods, whether in excess of a related reserve for legal or tax contingencies or where there is no such reserve, and for which the Company is able to estimate a range of possible loss, the current estimated range is zero to $450 million in excess of any reserves related to those matters. This range represents management’s estimate based on currently available information and does not represent the Company’s maximum loss exposure; actual results may vary significantly. As such legal proceedings evolve, the Company may need to increase its range of possible loss or reserves.

Based on its current knowledge, and taking into consideration its litigation-related liabilities, the Company believes it is not a party to, nor are any of its properties the subject of, any legal proceeding that would have a material adverse effect on the Company’s consolidated financial condition or liquidity. However, in light of the uncertainties involved in such matters, it is possible that the outcome of legal proceedings, including the possible resolution of merchant claims, could have a material impact on the Company’s results of operations.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

9. Derivatives and Hedging Activities

The Company uses derivative financial instruments (derivatives) to manage exposures to various market risks. These instruments derive their value from an underlying variable or multiple variables, including interest rates, foreign exchange rates, and equity index or price, and are carried at fair value on the Consolidated Balance Sheets. These instruments enable end users to increase, reduce or alter exposure to various market risks and, for that reason, are an integral component of the Company’s market risk management. The Company does not transact in derivatives for trading purposes.

In relation to the Company’s credit risk, under the terms of the derivative agreements it has with its various counterparties, the Company is not required to either immediately settle any outstanding liability balances or post collateral upon the occurrence of a specified credit risk-related event. Based on its assessment of the credit risk of the Company’s derivative counterparties as of June 30, 2017 and December 31, 2016, no credit risk adjustment to the derivative portfolio was required.

The following table summarizes the total fair value, excluding interest accruals, of derivative assets and liabilities as of June 30, 2017and December 31, 2016:

		Other Assets Fair Value				Other Liabilities Fair Value
(Millions)		2017		2016		2017		2016

• Effective January 2017, the Central Clearing Party (CCP) changed the legal characterization of variation margin payments for centrally cleared derivatives to be settlement payments, as opposed to collateral. As of June 30, 2017 centrally cleared derivatives are fully collateralized. The Company also maintained several bilateral interest rate contracts that are not subject to the CCP’s rule change and amounts related to such contracts are shown gross of any collateral exchanged.
• Includes foreign currency derivatives embedded in certain operating agreements.
• Primarily represents the offsetting of bilateral interest rate contracts and the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from derivatives executed with the same counterparty under an enforceable master netting arrangement.
• The Company held no non-cash collateral as of June 30, 2017. As of December 31, 2016, the Company received non-cash collateral from a counterpartyin the form of security interests in U.S. Treasury securities,with a fair value of $18 million, none of which was sold or repledged. Such non-cash collateral economically reduced the Company’s risk exposure to $537 million as of December 31,2016, but did not reduce the net exposure on the Company’s Consolidated Balance Sheets. Additionally, the Company posted $170 million and $169 million as of June 30, 2017 and December 31, 2016, respectively, as initial margin on its centrally cleared interest rate swaps; such amounts are recorded within Other receivables on the Consolidated Balance Sheets and are not netted against the derivative balances.
• Represents the amount of netting of derivative assets and derivative liabilities executed with the same counterparty under an enforceable master netting arrangement.
• The Company has no individually significant derivative counterparties and therefore, no significant risk exposure to any single derivative counterparty. The total net derivative assets and net derivative liabilities are presented within Other assets and Other liabilities, respectively, on the Consolidated Balance Sheets.

A majority of the Company’s derivative assets and liabilities as of June 30, 2017 and December 31, 2016 are subject to master netting agreements with its derivative counterparties. The Company has no derivative amounts subject to enforceable master netting arrangements that are not offset on the Consolidated Balance Sheets.

Fair Value Hedges

The Company is exposed to interest rate risk associated with its fixed-rate long-term debt obligations. At the time of issuance, certain fixed-rate debt obligations are designated in fair value hedging relationships, using interest rate swaps, to economically convert the fixed interest rate to a floating interest rate. The Company has $19.5 billion and $17.7 billion of fixed-rate debt obligations designated in fair value hedgingrelationships as of June 30, 2017 and December 31, 2016, respectively.

The following table summarizes the gains (losses) recognized in Other expenses associated with the Company’s fair value hedges for the three andsix months endedJune 30:

		Three Months Ended June 30,				Six Months Ended June 30,
(Millions)	2017		2016		2017		2016
Interest rate derivative contracts	$	6	$	61	$	(69)	$	226
Hedged items		(25)		(53)		25		(224)
Net hedge ineffectiveness	$	(19)	$	8	$	(44)	$	2

The Company also recognized a net reduction in interest expense on long-term debt of $37 million and $59 million for the three months ended June 30, 2017 and 2016, respectively, and $81 million and $118 million for the six months ended June 30,2017 and 2016, respectively, primarily related to the net settlements (interest accruals) on the Company’s interest rate derivatives designated as fair value hedges.

Net Investment Hedges

The effective portion of the gain or loss on net investment hedges, net of taxes, recorded in AOCI as part of the cumulative translation adjustment, was a loss of $102 million and a gain of $135 million for the three months ended June 30, 2017 and 2016, respectively, and a loss of $331 million and a gain of $43 million for the six months ended June 30, 2017 and 2016, respectively, with any ineffective portion recognized in Other expenses during the period.

Income Taxes

14. Income Taxes

The effective tax rate was 31.2 percent and 33.2 percent for the three months ended June 30, 2017 and 2016, respectively, and 31.6 percent and 33.8 percent for the six months ended June 30, 2017 and 2016, respectively. The changes in tax rates primarily reflected the geographic mix of business and the level of pretax income in relation to recurring permanent tax benefits. In addition, the effective tax rate in the current year reflected the resolution of certain prior years’ tax items.

The Company is under continuous examination by the Internal Revenue Service (IRS) and tax authorities in other countries and states in which the Company has significant business operations. The tax years under examination and open for examination vary by jurisdiction.In February 2017, the Company received notification that all matters outstanding with the IRS for tax years 1997-2007 were resolved. The resolution of such matters did not have a material impact on the Company’s effective tax rate. The Company is currently under examination with the IRS for tax years 2008 through 2014.

The Company believes it is reasonably possible that its unrecognized tax benefits could decrease within the next 12 months by as much as $133million, principally as a result of potential resolutions of prior years’ tax items with various taxing authorities. The prior years’ tax items include unrecognized tax benefits relating to the deductibility of certain expenses or losses and the attribution of taxable income to a particular jurisdiction or jurisdictions. Of the $133 million of unrecognized tax benefits, approximately $90 million relates to amounts that, if recognized, would impact the effective tax rate in a future period.During the six months ended June 30, 2017, the Company’s unrecognized tax benefits decreased by $280 million. The decrease was primarily due to the resolution with the IRS of an uncertain tax position in January 2017, which resulted in the recognition of $289 million in shareholders’ equity, specifically within AOCI.

• The Company’s unvested restricted stock awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator.
• The dilutive effect of unexercised stock options excludes from the computation of EPS 1.2 million and 2.5 million of options for the three months ended June 30, 2017 and 2016, respectively, and 1.2 million and 1.7 million of options for the six months endedJune 30, 2017 and 2016, respectively, because inclusion of the options would have been anti-dilutive.

Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2017

Policy (Text Block) [Abstract]

Basis of Presentation

The preparation of Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. These accounting estimates reflect the best judgment of management, but actual results could differ.

Investments

Investment securities principally include debt securities the Company classifies as available-for-sale and carries at fair value on the Consolidated Balance Sheets, with unrealized gains and losses recorded in accumulated other comprehensive income (loss) (AOCI), net of income taxes. Realized gains and losses are recognized upon disposition of the securities using the specific identification method.

Contingencies

The Company has recorded reserves for certain of its outstanding legal proceedings. A reserve is recorded when it is both (a) probable that a loss has occurred and (b) the amount of loss can be reasonably estimated. There may be instances in which an exposure to loss exceeds the recorded reserve. The Company evaluates, on a quarterly basis, developments in legal proceedings that could cause an increase or decrease in the amount of the reserve that has been previously recorded, or a revision to the disclosed estimated range of possible losses, as applicable.

Derivatives

The Company uses derivative financial instruments (derivatives) to manage exposures to various market risks. These instruments derive their value from an underlying variable or multiple variables, including interest rates, foreign exchange rates, and equity index or price, and are carried at fair value on the Consolidated Balance Sheets.

The changes in the fair value of derivatives that are not designated as hedges are intended to offset the related foreign exchange gains or losses of the underlying foreign currency exposures.

Guarantees

The Company’s recognition of these instruments is at fair value. In addition, the Company establishes reserves when a loss is probable and the amount can be reasonably estimated.

• For Global Corporate Payments (GCP) Card Member loans and receivables in Global Commercial Services (GCS), delinquency data is tracked based on days past billing status rather than days past due. A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member’s billing statement date. In addition, if the Company initiates collection procedures on an account prior to the account becoming 90 days past billing, the associated Card Member loan and receivable balance is classified as 90 days past billing. These amounts are shown above as 90+ Days Past Due for presentation purposes. See also (b).
• Delinquency data for periods other than 90 days past billing is not available due to system constraints. Therefore, such data has not been utilized for risk management purposes. The balances that are current to 89 days past due can be derived as the difference between the Total and the 90+ Days Past Due balances.

• Effective January 2017, the Central Clearing Party (CCP) changed the legal characterization of variation margin payments for centrally cleared derivatives to be settlement payments, as opposed to collateral. As of June 30, 2017 centrally cleared derivatives are fully collateralized. The Company also maintained several bilateral interest rate contracts that are not subject to the CCP’s rule change and amounts related to such contracts are shown gross of any collateral exchanged.
• Includes foreign currency derivatives embedded in certain operating agreements.
• Primarily represents the offsetting of bilateral interest rate contracts and the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from derivatives executed with the same counterparty under an enforceable master netting arrangement.
• The Company held no non-cash collateral as of June 30, 2017. As of December 31, 2016, the Company received non-cash collateral from a counterpartyin the form of security interests in U.S. Treasury securities,with a fair value of $18 million, none of which was sold or repledged. Such non-cash collateral economically reduced the Company’s risk exposure to $537 million as of December 31,2016, but did not reduce the net exposure on the Company’s Consolidated Balance Sheets. Additionally, the Company posted $170 million and $169 million as of June 30, 2017 and December 31, 2016, respectively, as initial margin on its centrally cleared interest rate swaps; such amounts are recorded within Other receivables on the Consolidated Balance Sheets and are not netted against the derivative balances.
• Represents the amount of netting of derivative assets and derivative liabilities executed with the same counterparty under an enforceable master netting arrangement.
• The Company has no individually significant derivative counterparties and therefore, no significant risk exposure to any single derivative counterparty. The total net derivative assets and net derivative liabilities are presented within Other assets and Other liabilities, respectively, on the Consolidated Balance Sheets.

Basic EPS			$	1.47	$	2.11	$	2.81	$	3.55
Diluted EPS			$	1.47	$	2.10	$	2.80	$	3.54

• The Company’s unvested restricted stock awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator.
• The dilutive effect of unexercised stock options excludes from the computation of EPS 1.2 million and 2.5 million of options for the three months ended June 30, 2017 and 2016, respectively, and 1.2 million and 1.7 million of options for the six months endedJune 30, 2017 and 2016, respectively, because inclusion of the options would have been anti-dilutive.
