Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of presentation JPMorgan Chase & Co. (“JPMorgan Chase” or “the Firm”), a financial holding company incorporated under Delaware law in 1968, is a leading global financial services firm and one of the largest banking institutions in the U.S., with operations worldwide. The Firm is a leader in investment banking, financial services for consumers and small businesses, commercial banking, financial transaction processing and asset management. Refer to Note 25 for a further discussion of the Firm’s business segments. The accounting and financial reporting policies of JPMorgan Chase and its subsidiaries conform to U.S. GAAP. Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by regulatory authorities. The unaudited Consolidated Financial Statements prepared in conformity with U.S. GAAP require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expense, and the disclosures of contingent assets and liabilities. Actual results could be different from these estimates. In the opinion of management, all normal, recurring adjustments have been included such that this interim financial information is fairly presented. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements, and related notes thereto, included in JPMorgan Chase’s 2018 Form 10-K. Certain amounts reported in prior periods have been reclassified to conform with the current presentation. Consolidation The Consolidated Financial Statements include the accounts of JPMorgan Chase and other entities in which the Firm has a controlling financial interest. All material intercompany balances and transactions have been eliminated. Assets held for clients in an agency or fiduciary capacity by the Firm are not assets of JPMorgan Chase and are not included on the Consolidated balance sheets. The Firm determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity. Refer to Notes 1 and 14 of JPMorgan Chase’s 2018 Form 10-K for a further description of JPMorgan Chase’s accounting policies regarding consolidation. Offsetting assets and liabilities U.S. GAAP permits entities to present derivative receivables and derivative payables with the same counterparty and the related cash collateral receivables and payables on a net basis on the Consolidated balance sheets when a legally enforceable master netting agreement exists. U.S. GAAP also permits securities financing activities to be presented on a net basis when specified conditions are met, including the existence of a legally enforceable master netting agreement. The Firm has elected to net such balances when the specified conditions are met. Refer to Note 1 of JPMorgan Chase’s 2018 Form 10-K for further information on offsetting assets and liabilities. Income tax expense The Firm’s effective tax rate was 20.4% and 17.9% in the three and nine months ended September 30, 2019, respectively, and 21.6% and 20.4% in the respective 2018 periods. For the nine months ended September 30, 2019, the effective tax rate reflected the recognition of $1.0 billion in tax benefits related to the resolution of certain tax audits, which reduced the Firm’s effective tax rate by 3.0%. Refer to Note 24 of JPMorgan Chase’s 2018 Form 10-K for further information.
