New Accounting Standards

We adopted new accounting standards related to revenue recognition and leases effective July 1, 2017.The prior periods presented here have been restated to reflect adoption of these new standards.

Non-GAAP Definition

Restructuring Expenses. We recorded $306 million of restructuring charges primarily related to our sales and marketing restructuring plan during the three months ended June 30, 2017.

TCJA Impact. We recorded a benefit of $104 million during the three months ended June 30, 2018 and a net charge of $13.7 billion during the twelve months ended June 30, 2018 related to TCJA. As of June 30, 2018, we have not completed our accounting for the tax effects of TCJA. Our net charge is provisional based on reasonable estimates for those tax effects. Changes to these estimates or new guidance issued by regulators may materially impact our provision for income taxes and effective tax rate in the period in which the adjustments are made. Our accounting for the tax effects of TCJA will be completed during the measurement period, which should not extend beyond the second fiscal quarter of 2019.

We have provided non-GAAP financial measures related to restructuring expenses and TCJA to aid investors in better understanding our performance. We believe these non-GAAP measures aid investors by providing additional insight into our operational performance and help clarify trends affecting our business. For comparability of reporting, management considers non-GAAP measures in conjunction with GAAP financial results in evaluating business performance. The non-GAAP financial measures presented in this release should not be considered as a substitute for, or superior to, the measures of financial performance prepared in accordance with GAAP.

Constant Currency

Microsoft presents constant currency information to provide a framework for assessing how our underlying businesses performed excluding the effect of foreign currency rate fluctuations. To present this information, current and comparative prior period results for entities reporting in currencies other than United States dollars are converted into United States dollars using the average exchange rates from the comparative period rather than the actual exchange rates in effect during the respective periods. All growth comparisons relate to the corresponding period in the last fiscal year. Microsoft has provided this non-GAAP financial information to aid investors in better understanding our performance. The non-GAAP financial measures presented in this release should not be considered as a substitute for, or superior to, the measures of financial performance prepared in accordance with GAAP.
