Basis of Presentation	BASIS OF PRESENTATION General Information Management believes the accompanying unaudited Consolidated Financial Statements contain all adjustments, including normal recurring items, considered necessary to fairly present the financial position of Stryker Corporation and its consolidated subsidiaries (the "Company," "we," us" or "our") on September 30, 2018 and the results of operations for the three and nine months 2018. The results of operations included in these Consolidated Financial Statements may not necessarily be indicative of our annual results.

New Accounting Pronouncements Not Yet Adopted We evaluate all Accounting Standards Updates (ASUs) issued by the Financial Accounting Standards Board (FASB) for consideration of their applicability.

On January 1, 2018 we adopted ASU 2018-02, Income Statements - Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which was issued in February 2018 and provides guidance allowing for the reclassification of stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 from accumulated other comprehensive income to retained earnings.
