Prepared Remarks:

Operator

Greetings, and welcome to the Microsoft fiscal year 2022 fourth-quarter earnings conference call. [Operator instructions] As a reminder, this conference is being recorded. It is now my pleasure to introduce your host, Brett Iversen, vice president of investor relations. Thank you.

You may begin.

Brett Iversen -- Vice President, Investor Relations

Good afternoon, and thank you for joining us today. On the call with me are Satya Nadella, chairman and chief executive officer; Amy Hood, chief financial officer; Alice Jolla, chief accounting officer; and Keith Dolliver, deputy general counsel. On the Microsoft Investor Relations website, you can find our earnings press release and financial summary slide deck, which is intended to supplement our prepared remarks during today's call and provides a reconciliation of differences between GAAP and non-GAAP financial measures. Unless otherwise specified, we will refer to non-GAAP metrics on the call.

The non-GAAP financial measures provided should not be considered as a substitute for or superior to the measures of financial performance prepared in accordance with GAAP. They are included as additional clarifying items to aid investors in further understanding the company's fourth-quarter performance in addition to the impact these items and events have on the financial results. All growth comparisons we make on the call today relate to the corresponding period of last year, unless otherwise noted. We will also provide growth rates in constant currency when available as a framework for assessing how our underlying businesses performed, excluding the effect of foreign currency rate fluctuations.

Where growth rates are the same in constant currency, we will refer to the growth rate only. We will post our prepared remarks to our website immediately following the call until the complete transcript is available. Today's call is being webcast live and recorded. If you ask a question, it will be included in our live transmission, in the transcript, and in any future use of the recording.

You can replay the call and view the transcript on the Microsoft Investor Relations website. During this call, we'll be making forward-looking statements, which are predictions, projections, or other statements about future events. These statements are based on current expectations and assumptions that are subject to risks and uncertainties. Actual results could materially differ because of factors discussed in today's earnings press release and the comments made during this conference call and in the Risk Factors section of our Form 10-K, Forms 10-Q, and other reports and filings with the Securities and Exchange Commission.
