Restrictions on Cash and Intercompany Funds Transfers	Restrictions on cash and intercompany funds transfers The business of JPMorgan Chase Bank, National Association (“JPMorgan Chase Bank, N.A.”) is subject to examination and regulation by the Office of the Comptroller of the Currency. The Bank is a member of the U.S. Federal Reserve System, and its deposits in the U.S. are insured by the FDIC. The Federal Reserve requires depository institutions to maintain cash reserves with a Federal Reserve Bank. The average required amount of reserve balances deposited by the Firm’s bank subsidiaries with various Federal Reserve Banks was approximately $14.4 billion and $10.6 billion in 2015 and 2014, respectively. Restrictions imposed by U.S. federal law prohibit JPMorgan Chase & Co. (“Parent Company”) and certain of its affiliates from borrowing from banking subsidiaries unless the loans are secured in specified amounts. Such secured loans provided by any banking subsidiary to the Parent Company or to any particular affiliate, together with certain other transactions with such affiliate, (collectively referred to as “covered transactions”), are generally limited to 10% of the banking subsidiary’s total capital, as determined by the risk-based capital guidelines; the aggregate amount of covered transactions between any banking subsidiary and all of its affiliates is limited to 20% of the banking subsidiary’s total capital. The principal sources of JPMorgan Chase’s income (on a parent company-only basis) are dividends and interest from JPMorgan Chase Bank, N.A., and the other banking and nonbanking subsidiaries of JPMorgan Chase. In addition to dividend restrictions set forth in statutes and regulations, the Federal Reserve, the Office of the Comptroller of the Currency (“OCC”) and the FDIC have authority under the Financial Institutions Supervisory Act to prohibit or to limit the payment of dividends by the banking organizations they supervise, including JPMorgan Chase and its subsidiaries that are banks or bank holding companies, if, in the banking regulator’s opinion, payment of a dividend would constitute an unsafe or unsound practice in light of the financial condition of the banking organization. At January 1, 2016, JPMorgan Chase’s banking subsidiaries could pay, in the aggregate, approximately $25 billion in dividends to their respective bank holding companies without the prior approval of their relevant banking regulators. The capacity to pay dividends in 2016 will be supplemented by the banking subsidiaries’ earnings during the year. In compliance with rules and regulations established by U.S. and non-U.S. regulators, as of December 31, 2015 and 2014, cash in the amount of $12.6 billion and $16.8 billion, respectively, were segregated in special bank accounts for the benefit of securities and futures brokerage customers. Also, as of December 31, 2015 and 2014, the Firm had receivables within other assets of $16.2 billion and $14.9 billion, respectively, consisting of cash deposited with clearing organizations for the benefit of customers. Securities with a fair value of $20.0 billion and $10.1 billion, respectively, were also restricted in relation to customer activity. In addition, as of December 31, 2015 and 2014, the Firm had other restricted cash of $3.7 billion and $3.3 billion, respectively, primarily representing cash reserves held at non-U.S. central banks and held for other general purposes.
