In addition, the net payable arising from unsettled trades would be reflected in those captions. A broker-dealer that purchases securities, either for its own account or for a customer's account, but does not receive the securities on the settlement date records the amount of money representing the purchase price of the securities, including any accrued interest, as a liability to the selling broker-dealer. This liability is paid when the securities are received by the purchasing broker-dealer.</definition>

  <Element Id="jpm_CashAndCashEquivalentsUnrestrictedCashAndCashEquivalentsPolicyTextBlock">
    <definition>A description of a company's cash and cash equivalents accounting policy with respect to unrestricted balances.  An entity shall disclose its policy for determining which items are treated as cash equivalents, including (1) whether the entity's cash and cash equivalents are insured or expose the entity to credit risk, (2) the classification of any negative balance accounts (overdrafts), and (3) the carrying basis of cash equivalents (for example, at cost) and whether the carrying amount of cash equivalents approximates fair value. Cash includes currency on hand as well as demand deposits with banks or financial institutions.  It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty.  In addition, cash equivalents include short-term, highly liquid investments that are both readily convertible to known amounts 
of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates.  Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment.  For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents.  However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months.</definition>

An enterprise may also categorize such a security as trading without the intent to sell it in the near term assuming the decision to categorize the security as trading occurred at acquisition; this is the reason why the trading category of investments in debt and equity securities are bought and sold "principally" for sale in the near term. Transfers into and out of the trading category should be rare. Such financial instruments that are held as of the reporting date are measured at fair value with unrealized holding gains and losses (
the difference between fair value and the previously reported carrying amount) included in earnings. (2) Fair values as of the balance sheet date of all assets resulting from contracts that meet the criteria of being accounted for as derivative instruments, net of the effects of master netting arrangements.</definition>

Combination of: 1) Revenue recognized in the period for (A) performance (incentive) fees based on the investment results achieved for management of certain institutional accounts and hedge funds, (B) schedule-based fees earned for management of mutual funds and closed-end funds, based either on average daily net assets or on a combination of the average daily net assets and gross income, and (C) other investment management and advisory fees. 2) Acting as an agent, a broker-dealer may buy and sell securities on behalf of its customers. In return for such services, the broker-dealer charges a commission. Each time a customer enters into a buy or sell transaction, a commission is earned by the broker-dealer for its selling and administrative efforts. For securities purchased, the commission is recorded as a receivable from customers; for securities sold, it is recorded as reductions in the payable to customers. Commissions earned a
re usually related to the broker-dealer's customers' trading volume and the dollar amounts of the trades. In general, commissions are for smaller trades of exchange-listed stocks and bonds made by retail customers. 3)Income from services rendered by trust departments or by any consolidated subsidiaries acting in a fiduciary capacity, including fees earned for (A) acting as an agent for fiduciary placement and loans and (B) custody or investment advisory services when such fees are not separately billed to the customer.

The disclosure should indicate the nature of the uncertainty and include an indication that it is at least reasonably possible that a change in the es
timate will occur in the near term. Disclosure of the factors that cause the estimate to be sensitive to change also is encouraged. Entities also may identify those areas that are subject to significant estimates.</definition>
