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) (“ASU 2014-09”), which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. 

The original effective date for ASU 2014-09 would have required the Company to adopt beginning in its first quarter of 2018. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date, which defers the effective date of ASU 2014-09 for one year and permits early adoption as early as the original effective date of ASU 2014-09. Accordingly, the Company may adopt the standard in either its first quarter of 2018 or 2019. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption.

As of September 26, 2015 and September 27, 2014, the Company’s cash, cash equivalents and marketable securities held by foreign subsidiaries were $186.9 billion and $137.1 billion, respectively, and are generally based in U.S. dollar-denominated holdings. Amounts held by foreign subsidiaries are generally subject to U.S. income taxation on repatriation to the U.S. The Company’s marketable securities investment portfolio is invested primarily in highly-rated securities and its investment policy generally limits the amount of credit exposure to any one issuer. The policy requires investments generally to be investment grade with the objective of minimizing the potential risk of principal loss. 

During 2015, cash generated from operating activities of $81.3 billion was a result of $53.4 billion of net income, non-cash adjustments to net income of $16.2 billion and an increase in the net change in operating assets and liabilities of $11.7 billion. Cash used in investing activities of $56.3 billion during 2015 consisted primarily of cash used for purchases of
