Fair Value [Abstract]
Fair Values	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, based on the Company's principal or, in the absence of a principal, most advantageous market for the specific asset or liability. GAAP provides for a three-level hierarchy of inputs to valuation techniques used to measure fair value, defined as follows: Level 1 ― Inputs that are quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access. Level 2 ― Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability, including: - Quoted prices for similar assets or liabilities in active markets; - Quoted prices for identical or similar assets or liabilities in markets that are not active; - Inputs other than quoted prices that are observable for the asset or liability; and - Inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 ― Inputs that are unobservable and reflect the Company's own estimates about the estimates market participants would use in pricing the asset or liability based on the best information available in the circumstances (e.g., internally derived assumptions surrounding the timing and amount of expected cash flows).
Accounts Receivable And Loans and Reserves For Card Member Losses [Abstract]
Card Member and Other Receivables and Loans	Card Member and Other Receivables Card Member receivables, representing amounts due from charge card product customers, are recorded at the time a Card Member enters into a point-of-sale transaction with a merchant. Each charge card transaction is authorized based on its likely economics reflecting a Card Member's most recent credit information and spend patterns. Additionally, global spend limits are established to limit the maximum exposure for the Company. Charge card customers generally must pay the full amount billed each month. Card Member receivable balances are presented on the Consolidated Balance Sheets net of reserves for losses (refer to Note 4), and include principal and any related accrued fees. Card Member and Other Loans Card Member loans, representing amounts due from lending card product customers, are recorded at the time a Card Member enters into a point-of-sale transaction with a merchant, as well as amounts due from charge card product customers when a Card Member enters into an extended payment arrangement with the Company. The Company's lending portfolios primarily include revolving loans to Card Members obtained through either their credit card accounts or the lending on charge feature of their charge card accounts. These loans have a range of terms such as credit limits, interest rates, fees and payment structures, which can be revised over time based on new information about Card Members and in accordance with applicable regulations and the respective product's terms and conditions. Card Members holding revolving loans are typically required to make monthly payments based on pre-established amounts. The amounts that Card Members choose to revolve are subject to finance charges. Card Member loans are presented on the Consolidated Balance Sheets net of reserves for losses (refer to Note 4), and include principal, accrued interest and fees receivable. The Company's policy generally is to cease accruing interest on a Card Member loan at the time the account is written off, and establish reserves for interest that the Company believes will not be collected. Impaired Card Member Loans and Receivables Impaired loans and receivables are defined by GAAP as individual larger balance or homogeneous pools of smaller balance restructured 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. The Company considers impaired loans and receivables to include: (i) loans over 90 days past due still accruing interest, (ii) non-accrual loans, and (iii) loans and receivables modified as troubled debt restructurings (TDRs). The Company may modify, through various company sponsored programs, Card Member loans and receivables in instances where the Card Member is experiencing financial difficulty to minimize losses while providing Card Members with temporary or permanent financial relief. The Company has classified Card Member loans and receivables in these modification programs as TDRs. Such modifications to the loans and receivables may include (i) reducing the interest rate (as low as zero percent, in which case the loan is characterized as non-accrual in the Company's TDR disclosures), (ii) reducing the outstanding balance (in the event of a settlement), (iii) suspending delinquency fees until the Card Member exits the modification program and (iv) placing the Card Member on a fixed payment plan not to exceed 60 months. Upon entering the modification program, the Card Member's ability to make future purchases is either cancelled or in certain cases suspended until the Card Member successfully exits the modification program. In accordance with the modification agreement with the Card Member, loans revert back to the original contractual terms (including the contractual interest rate) when the Card Member exits the modification program, which is either (i) when all payments have been made in accordance with the modification agreement or (ii) when the Card Member defaults out of the modification program. In either case, the Company establishes a reserve for Card Member interest charges and fees considered to be uncollectible. The performance of a loan or a receivable modified as a TDR is closely monitored to understand its impact on the Company's reserve for losses. Though the ultimate success of modification programs remains uncertain, the Company believes the programs improve the cumulative loss performance of such loans and receivables. Reserves for Card Member loans and receivables modified as TDRs are determined as the difference between the cash flows expected to be received from the Card Member (taking into consideration the probability of subsequent defaults), discounted at the original effective interest rates, and the carrying value of the Card Member loan or receivable balance.
Reserves For Losses Policy [Abstract]
Reserves for losses	Reserves for losses relating to Card Member loans and receivables represent management's best estimate of the probable inherent losses in the Company's outstanding portfolio of loans and receivables, as of the balance sheet date. Management's evaluation process requires certain estimates and judgments. Reserves for losses are primarily based upon statistical models that analyze portfolio performance and reflect management's judgment regarding the quantitative components of the reserve. The models take into account several factors, including loss migration rates and average losses and recoveries over an appropriate historical period. Management considers whether to adjust the models for specific qualitative factors such as increased risk in certain portfolios, impact of risk management initiatives on portfolio performance and concentration of credit risk based on factors such as vintage, industry or geographic regions. In addition, management may increase or decrease the reserves for losses on Card Member loans for other external environmental qualitative factors, including various indicators related to employment, spend, sentiment, housing and credit, as well as the legal and regulatory environment. Generally, due to the short-term nature of Card Member receivables, the impact of additional external qualitative factors on the probable losses inherent within the Card Member receivables portfolio is not significant. As part of this evaluation process, management also considers various reserve coverage metrics, such as reserves as a percentage of past due amounts, reserves as a percentage of Card Member receivables or loans and net write-off coverage. Card Member loans and receivables balances are written off when management considers amounts to be uncollectible, which is generally determined by the number of days past due and is typically no later than 180 days past due. Card Member loans and receivables in bankruptcy or owed by deceased individuals are generally written off upon notification and recoveries are recognized as they are collected.
Investments [Abstract]
Investments	Investment securities include debt and equity securities classified as available for sale. The Company's investment securities, principally debt securities, are carried at fair value on the Consolidated Balance Sheets with unrealized gains (losses) recorded in AOCI, net of income taxes. Realized gains and losses are recognized in results of operations upon disposition of the securities using the specific identification method on a trade date basis. Overall, for the investment securities in gross unrealized loss positions identified above, (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.
Asset Securitization [Abstract]
Asset Securitizations	The Company periodically securitizes Card Member receivables and loans arising from its card business through the transfer of those assets to securitization trusts. The trusts then issue securities to third-party investors, collateralized by the transferred assets. Card Member receivables are transferred to the American Express Issuance Trust II (the Charge Trust II) During the third quarter of 2013, the Company transferred Card Member receivables from the American Express Issuance Trust (the Charge Trust) to the Charge Trust II, collectively referred to as the Charge Trusts. As of September 30, 2013, the Charge Trust was dissolved, and the Company will utilize the Charge Trust II for securitization of Card Member receivables.. Card Member loans are transferred to the American Express Credit Account Master Trust (the Lending Trust). The Charge Trust II and the Lending Trust are consolidated by American Express Travel Related Services Company, Inc. (TRS), which is a consolidated subsidiary of the Company. The trusts are considered VIEs as they have insufficient equity at risk to finance their activities, which are to issue securities that are collateralized by the underlying Card Member receivables and loans. TRS, in its role as servicer of the Charge Trust II and the Lending Trust, has the power to direct the most significant activity of the trusts, which is the collection of the underlying Card Member receivables and loans in the trusts. In addition, TRS, excluding its consolidated subsidiaries, owns approximately $0.7 billion of subordinated securities issued by the Lending Trust as of September 30, 2013. These subordinated securities have the obligation to absorb losses of the Lending Trust and provide the right to receive benefits from the Lending Trust, both of which are significant to the VIE. TRS' role as servicer for the Charge Trust II does not provide it with a significant obligation to absorb losses or a significant right to receive benefits. However, TRS' position as the parent company of the entities that transferred the receivables to the Charge Trust II makes it the party most closely related to the Charge Trust II. Based on these considerations, TRS is the primary beneficiary of both the Charge Trust II and the Lending Trust. The debt securities issued by the Charge Trust II and the Lending Trust are non-recourse to the Company. Securitized Card Member receivables and loans held by the Charge Trust II and the Lending Trust are available only for payment of the debt securities or other obligations issued or arising in the securitization transactions. The long-term debt of each trust is payable only out of collections on their respective underlying securitized assets.
Derivatives And Hedging Activities [Abstract]
Derivatives	Derivative Financial Instruments that Qualify for Hedge Accounting Derivatives executed for hedge accounting purposes are documented and designated as such when the Company enters into the contracts. In accordance with its risk management policies, the Company structures its hedges with terms similar to that of the item being hedged. The Company formally assesses, at inception of the hedge accounting relationship and on a quarterly basis, whether derivatives designated as hedges are highly effective in offsetting the fair value or cash flows of the hedged items. These assessments usually are made through the application of a regression analysis method. If it is determined that a derivative is not highly effective as a hedge, the Company will discontinue the application of hedge accounting. Fair Value Hedges A fair value hedge involves a derivative designated to hedge the Company's exposure to future changes in the fair value of an asset or a liability, or an identified portion thereof that is attributable to a particular risk. Interest Rate Contracts The Company is exposed to interest rate risk associated with its fixed-rate long-term debt. The Company uses interest rate swaps to economically convert certain fixed-rate long-term debt obligations to floating-rate obligations at the time of issuance. As of September 30, 2013 and December 31, 2012, the Company hedged $14.7 billion and $18.4 billion, respectively, of its fixed-rate debt to floating-rate debt using interest rate swaps. To the extent the fair value hedge is effective, the gain or loss on the hedging instrument offsets the loss or gain on the hedged item attributable to the hedged risk. Any difference between the changes in the fair value of the derivative and the hedged item is referred to as hedge ineffectiveness and is reflected in earnings as a component of other expenses. Hedge ineffectiveness may be caused by differences between the debt's interest coupon and the benchmark rate, primarily due to credit spreads at inception of the hedging relationship that are not reflected in the valuation of the interest rate swap. Furthermore, hedge ineffectiveness may be caused by changes in the relationship between 3-month LIBOR and 1-month LIBOR, as well as between the overnight indexed swap (OIS) and 1-month LIBOR, as basis spreads may impact the valuation of the interest rate swap without causing an offsetting impact in the value of the hedged debt. If a fair value hedge is de-designated or no longer considered to be effective, changes in fair value of the derivative continue to be recorded through earnings but the hedged asset or liability is no longer adjusted for changes in fair value resulting from changes in interest rates. The existing basis adjustment of the hedged asset or liability is amortized or accreted as an adjustment to yield over the remaining life of that asset or liability. Total Return Contract The Company hedges its exposure to changes in the fair value of its equity investment in ICBC in local currency. The Company uses a TRC to transfer this exposure to its derivative counterparty. As of September 30, 2013 and December 31, 2012, the fair value of the equity investment in ICBC was $167 million (239.5 million shares) and $295 million (415.9 million shares), respectively. To the extent the hedge is effective, the gain or loss on the TRC offsets the loss or gain on the investment in ICBC. Any difference between the changes in the fair value of the derivative and the hedged item results in hedge ineffectiveness and is recognized in other expenses in the Consolidated Statements of Income. Cash Flow Hedges A cash flow hedge involves a derivative designated to hedge the Company's exposure to variable future cash flows attributable to a particular risk. Such exposures may relate to either an existing recognized asset or liability or a forecasted transaction. The Company hedges existing long-term variable-rate debt, the rollover of short-term borrowings and the anticipated forecasted issuance of additional funding through the use of derivatives, primarily interest rate swaps. These derivative instruments economically convert floating-rate debt obligations to fixed-rate obligations for the duration of the instrument. As of September 30, 2013 and December 31, 2012, the Company did not hedge any of its floating-rate debt using interest rate swaps. For derivatives designated as cash flow hedges, the effective portion of the gain or loss on the derivatives is recorded in AOCI and reclassified into earnings when the hedged cash flows are recognized in earnings. The amount that is reclassified into earnings is presented in the Consolidated Statements of Income in the same line item in which the hedged instrument or transaction is recognized, primarily in interest expense. Any ineffective portion of the gain or loss on the derivatives is reported as a component of other expenses. If a cash flow hedge is de-designated or terminated prior to maturity, the amount previously recorded in AOCI is recognized into earnings over the period that the hedged item impacts earnings. If a hedge relationship is discontinued because it is probable that the forecasted transaction will not occur according to the original strategy, any related amounts previously recorded in AOCI are recognized into earnings immediately. No ineffectiveness or other amounts were reclassified from AOCI into income for the three and nine months ended September 30, 2013 and the three months ended September 30, 2012. For the nine months ended September 30, 2012, an amount of $(1) million loss was reclassified from AOCI into income. In the normal course of business, as the hedged cash flows are recognized into earnings, the Company does not expect to reclassify any amount of net pretax losses on derivatives from AOCI into earnings during the next 12 months. Net Investment Hedges A net investment hedge is used to hedge future changes in currency exposure of a net investment in a foreign operation. The Company primarily designates foreign currency derivatives, typically foreign exchange forwards, and on occasion foreign currency denominated debt, as hedges of net investments in certain foreign operations. These instruments reduce exposure to changes in currency exchange rates on the Company's investments in non-U.S. subsidiaries. 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 $(123) million and $(320) million for the three months ended September 30, 2013 and 2012, respectively, and was $160 million and $(294) million for the nine months ended September 30, 2013 and 2012, respectively. Any ineffective portion of the gain or (loss) on net investment hedges is recognized in other expenses during the period of change. No ineffectiveness or other amounts were reclassified from AOCI into income for the three and nine months ended September 30, 2013 and 2012. Derivatives Not Designated as Hedges The Company has derivatives that act as economic hedges, but are not designated as such for hedge accounting purposes. Foreign currency transactions and non-U.S. dollar cash flow exposures from time to time may be partially or fully economically hedged through foreign currency contracts, primarily foreign exchange forwards, options and cross-currency swaps. These hedges generally mature within one year. Foreign currency contracts involve the purchase and sale of a designated currency at an agreed upon rate for settlement on a specified date. The changes in the fair value of the derivatives effectively offset the related foreign exchange gains or losses on the underlying balance sheet exposures. From time to time, the Company may enter into interest rate swaps to specifically manage funding costs related to its proprietary card business. The Company has certain operating agreements containing payments that may be linked to a market rate or price, primarily foreign currency rates. The payment components of these agreements may meet the definition of an embedded derivative, in which case the embedded derivative is accounted for separately and is classified as a foreign exchange contract based on its primary risk exposure. In addition, the Company holds an investment security containing an embedded equity-linked derivative. For derivatives that are not designated as hedges, changes in fair value are reported in current period earnings.
Commitments and Contingencies [Abstract]
Commitments and contingencies	The Company has recorded liabilities for certain of its outstanding legal proceedings and governmental examinations. A liability is accrued when it is both (a) probable that a loss has occurred and (b) the amount of loss can be reasonably estimated. As discussed below, there may be instances in which an exposure to loss exceeds the accrued liability. The Company evaluates, on a quarterly basis, developments in legal proceedings and governmental examinations that could cause an increase or decrease in the amount of the liability that has been previously accrued or a revision to the disclosed estimated range of possible losses, as applicable.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, based on the Company's principal or, in the absence of a principal, most advantageous market for the specific asset or liability.

GAAP provides for a three-level hierarchy of inputs to valuation techniques used to measure fair value, defined as follows:

Level 1 ― Inputs that are quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access.
Level 2 ― Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability, including:

- Quoted prices for similar assets or liabilities in active markets;

- Quoted prices for identical or similar assets or liabilities in markets that are not active;

- Inputs other than quoted prices that are observable for the asset or liability; and

- Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 ― Inputs that are unobservable and reflect the Company's own estimates about the estimates market participants would use in pricing the asset or liability based on the best information available in the circumstances (e.g., internally derived assumptions surrounding the timing and amount of expected cash flows).

Accounts Receivable And Loans and Reserves For Card Member Losses [Abstract]

Card Member and Other Receivables and Loans

Card Member and Other Receivables

Card Member receivables, representing amounts due from charge card product customers, are recorded at the time a Card Member enters into a point-of-sale transaction with a merchant. Each charge card transaction is authorized based on its likely economics reflecting a Card Member's most recent credit information and spend patterns. Additionally, global spend limits are established to limit the maximum exposure for the Company.

Charge card customers generally must pay the full amount billed each month. Card Member receivable balances are presented on the Consolidated Balance Sheets net of reserves for losses (refer to Note 4), and include principal and any related accrued fees.

Card Member and Other Loans

Card Member loans, representing amounts due from lending card product customers, are recorded at the time a Card Member enters into a point-of-sale transaction with a merchant, as well as amounts due from charge card product customers when a Card Member enters into an extended payment arrangement with the Company. The Company's lending portfolios primarily include revolving loans to Card Members obtained through either their credit card accounts or the lending on charge feature of their charge card accounts. These loans have a range of terms such as credit limits, interest rates, fees and payment structures, which can be revised over time based on new information about Card Members and in accordance with applicable regulations and the respective product's terms and conditions.

The Company's policy generally is to cease accruing interest on a Card Member loan at the time the account is written off, and establish reserves for interest that the Company believes will not be collected.

Impaired Card Member Loans and Receivables

Impaired loans and receivables are defined by GAAP as individual larger balance or homogeneous pools of smaller balance restructured 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. The Company considers impaired loans and receivables to include: (i) loans over 90 days past due still accruing interest, (ii) non-accrual loans, and (iii) loans and receivables modified as troubled debt restructurings (TDRs).

The Company may modify, through various company sponsored programs, Card Member loans and receivables in instances where the Card Member is experiencing financial difficulty to minimize losses while providing Card Members with temporary or permanent financial relief. The Company has classified Card Member loans and receivables in these modification programs as TDRs. Such modifications to the loans and receivables may include (i) reducing the interest rate (as low as zero percent, in which case the loan is characterized as non-accrual in the Company's TDR disclosures), (ii) reducing the outstanding balance (in the event of a settlement), (iii) suspending delinquency fees until the Card Member exits the modification program and (iv) placing the Card Member on a fixed payment plan not to exceed 60 months. Upon entering the modification program, the Card Member's ability to make future purchases is either cancelled or in certain cases suspended until the Card Member successfully exits the modification program. In accordance with the modification agreement with the Card Member, loans revert back to the original contractual terms (including the contractual interest rate) when the Card Member exits the modification program, which is either (i) when all payments have been made in accordance with the modification agreement or (ii) when the Card Member defaults out of the modification program.

To the extent the fair value hedge is effective, the gain or loss on the hedging instrument offsets the loss or gain on the hedged item attributable to the hedged risk. Any difference between the changes in the fair value of the derivative and the hedged item is referred to as hedge ineffectiveness and is reflected in earnings as a component of other expenses. Hedge ineffectiveness may be caused by differences between the debt's interest coupon and the benchmark rate, primarily due to credit spreads at inception of the hedging relationship that are not reflected in the valuation of the interest rate swap. Furthermore, hedge ineffectiveness may be caused by changes in the relationship between 3-month LIBOR and 1-month LIBOR, as well as between the overnight indexed swap (OIS) and 1-month LIBOR, as basis spreads may impact the valuation of the interest rate swap without causing an offsetting impact in the value of the hedged debt. If a fair value hedge is de-designated or no longer considered to be effective, changes in fair value of the derivative continue to be recorded through earnings but the hedged asset or liability is no longer adjusted for changes in fair value resulting from changes in interest rates. The existing basis adjustment of the hedged asset or liability is amortized or accreted as an adjustment to yield over the remaining life of that asset or liability.

Total Return Contract

The Company hedges its exposure to changes in the fair value of its equity investment in ICBC in local currency. The Company uses a TRC to transfer this exposure to its derivative counterparty. As of September 30, 2013 and December 31, 2012, the fair value of the equity investment in ICBC was $167 million (239.5 million shares) and $295 million (415.9 million shares), respectively. To the extent the hedge is effective, the gain or loss on the TRC offsets the loss or gain on the investment in ICBC. Any difference between the changes in the fair value of the derivative and the hedged item results in hedge ineffectiveness and is recognized in other expenses in the Consolidated Statements of Income.

Cash Flow Hedges

A cash flow hedge involves a derivative designated to hedge the Company's exposure to variable future cash flows attributable to a particular risk. Such exposures may relate to either an existing recognized asset or liability or a forecasted transaction. The Company hedges existing long-term variable-rate debt, the rollover of short-term borrowings and the anticipated forecasted issuance of additional funding through the use of derivatives, primarily interest rate swaps. These derivative instruments economically convert floating-rate debt obligations to fixed-rate obligations for the duration of the instrument. As of September 30, 2013 and December 31, 2012, the Company did not hedge any of its floating-rate debt using interest rate swaps.

For derivatives designated as cash flow hedges, the effective portion of the gain or loss on the derivatives is recorded in AOCI and reclassified into earnings when the hedged cash flows are recognized in earnings. The amount that is reclassified into earnings is presented in the Consolidated Statements of Income in the same line item in which the hedged instrument or transaction is recognized, primarily in interest expense. Any ineffective portion of the gain or loss on the derivatives is reported as a component of other expenses. If a cash flow hedge is de-designated or terminated prior to maturity, the amount previously recorded in AOCI is recognized into earnings over the period that the hedged item impacts earnings. If a hedge relationship is discontinued because it is probable that the forecasted transaction will not occur according to the original strategy, any related amounts previously recorded in AOCI are recognized into earnings immediately. No ineffectiveness or other amounts were reclassified from AOCI into income for the three and nine months ended September 30, 2013 and the three months ended September 30, 2012. For the nine months ended September 30, 2012, an amount of $(1) million loss was reclassified from AOCI into income.

In the normal course of business, as the hedged cash flows are recognized into earnings, the Company does not expect to reclassify any amount of net pretax losses on derivatives from AOCI into earnings during the next 12 months.

Net Investment Hedges

A net investment hedge is used to hedge future changes in currency exposure of a net investment in a foreign operation. The Company primarily designates foreign currency derivatives, typically foreign exchange forwards, and on occasion foreign currency denominated debt, as hedges of net investments in certain foreign operations. These instruments reduce exposure to changes in currency exchange rates on the Company's investments in non-U.S. subsidiaries. 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 $(123) million and $(320) million for the three months ended September 30, 2013 and 2012, respectively, and was $160 million and $(294) million for the nine months ended September 30, 2013 and 2012, respectively. Any ineffective portion of the gain or (loss) on net investment hedges is recognized in other expenses during the period of change. No ineffectiveness or other amounts were reclassified from AOCI into income for the three and nine months ended September 30, 2013 and 2012.

Derivatives Not Designated as Hedges

The Company has derivatives that act as economic hedges, but are not designated as such for hedge accounting purposes. Foreign currency transactions and non-U.S. dollar cash flow exposures from time to time may be partially or fully economically hedged through foreign currency contracts, primarily foreign exchange forwards, options and cross-currency swaps. These hedges generally mature within one year. Foreign currency contracts involve the purchase and sale of a designated currency at an agreed upon rate for settlement on a specified date. The changes in the fair value of the derivatives effectively offset the related foreign exchange gains or losses on the underlying balance sheet exposures. From time to time, the Company may enter into interest rate swaps to specifically manage funding costs related to its proprietary card business.

The Company has certain operating agreements containing payments that may be linked to a market rate or price, primarily foreign currency rates. The payment components of these agreements may meet the definition of an embedded derivative, in which case the embedded derivative is accounted for separately and is classified as a foreign exchange contract based on its primary risk exposure. In addition, the Company holds an investment security containing an embedded equity-linked derivative.

For derivatives that are not designated as hedges, changes in fair value are reported in current period earnings.

Commitments and Contingencies [Abstract]

Commitments and contingencies

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