Recent Accounting Pronouncements	2. Recent Accounting Pronouncements – In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” The ASU is a converged standard between the FASB and the IASB that provides a single comprehensive revenue recognition model for all contracts with customers across transactions and industries. The primary objective of the ASU is revenue recognition that represents the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU is effective for interim and annual reporting periods beginning after December 15, 2016. Northern Trust is currently assessing the impact of adoption of ASU 2014-09. In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” This ASU requires secured borrowing accounting treatment for repurchase-to-maturity transactions and provides guidance on accounting for repurchase financing arrangements. This ASU is effective for interim and annual reporting periods beginning after December 15, 2014. The adoption of this ASU will result in additional disclosures, but is not expected to impact significantly Northern Trust’s consolidated financial position or results of operations. In June 2014, the FASB also issued ASU No. 2014-12, “Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period.” This ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and should not be reflected in estimating the grant-date fair value of the award. This ASU is effective for interim and annual reporting periods beginning after December 15, 2015 with earlier adoption permitted. The adoption of this ASU is not expected to impact significantly Northern Trust’s consolidated financial position or results of operations.
