Accounting Developments	Accounting Developments Accounting Standards to be Adopted in Future Periods Retirement Benefits. In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The guidance impacts the presentation of net periodic pension costs in the statement of income. The update also allows the service cost to be eligible for capitalization, when applicable. The guidance is effective in the first quarter of fiscal 2019 and early adoption is permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Goodwill. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies goodwill impairment testing. The guidance is effective in the first quarter of fiscal 2021 and early adoption is permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Statement of Cash Flows. In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments. The guidance adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The guidance is effective in the first quarter of fiscal 2019 and early adoption is permitted. In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash. The guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. The guidance is effective in the first quarter of fiscal 2019 and early adoption is permitted. We are currently evaluating the impact of these new ASUs on our Consolidated Statements of Cash Flows. Financial Instruments-Credit Losses. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. The guidance provides for estimating credit losses on certain types of financial instruments by introducing an approach based on expected losses. The guidance is effective in the first quarter of fiscal 2021 and early adoption is permitted in the first quarter of fiscal 2020. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Leases. In February 2016, the FASB issued ASU No. 2016-02, Leases. The guidance affects the accounting for leases and provides for a lessee model that brings substantially all leases onto the balance sheet. The guidance is effective in the first quarter of fiscal 2019 and early adoption is permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements. Financial Instruments. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. The guidance is effective in the first quarter of fiscal 2019. We are currently evaluating the impact of the new guidance related to equity investments and the presentation and disclosure requirements of financial instruments on our consolidated financial statements. Early adoption is permitted for the accounting guidance on financial liabilities under the fair value option and we adopted this guidance in the first quarter of fiscal 2016. The adoption of this accounting guidance did not have a material effect on our consolidated financial statements. Revenue Recognition. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU No. 2014-09”). The accounting guidance defines how companies report revenues from contracts with customers, and also requires enhanced disclosures. The guidance, as stated in ASU No. 2014-09, was effective beginning in the first quarter of fiscal 2018. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers - Deferral of Effective Date, which defers the effective date by one year, with early adoption on the original effective date permitted. We intend to adopt the new guidance on December 1, 2017 with a cumulative-effect adjustment to opening member’s equity. Because the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other U.S. GAAP, we do not expect the guidance to have a material impact on the elements of our Consolidated Statements of Earnings most closely associated with financial instruments, including Principal transaction revenues, Interest income and Interest expense. Our implementation efforts include the identification of revenue within the scope of the guidance, the evaluation of certain revenue contracts, education and discussions with our control functions, and periodic discussions with our audit committee. Our evaluation of the impact of the new guidance on our consolidated financial statements is ongoing, and we continue to evaluate the timing of recognition for various revenues, which may be accelerated or deferred depending on the features of the client arrangements and the presentation of certain contract costs (whether presented gross or offset against revenues). Adopted Accounting Standards Employee Share-Based Payments. In March 2016, the FASB issued ASU No. 2016-09. The guidance simplifies various aspects related to how share-based payments are accounted for and presented in the consolidated financial statements. The amendments include the recognition of all excess tax benefits and tax deficiencies as income tax expense or benefit in the Consolidated Statement of Earnings and changes to the timing of recognition of excess tax benefits, the accounting for forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows. We early adopted this standard on December 1, 2016 and the adoption did not have a material effect on our consolidated financial statements. We elected to account for forfeitures as they occur, which results in dividends and dividend equivalents originally charged against retained earnings for forfeited shares to be reclassified to compensation cost in the period in which the forfeiture occurs. In addition, the current period’s excess tax benefit related to stock-based compensation is presented as an operating activity rather than a financing activity in the Consolidated Statements of Cash Flows on a retrospective basis.
