New Reporting Segments

Effective October 1, 2012, Hyatt Hotels Corporation (the "Company," "we," "our" or "us") realigned its corporate and regional operations. Our realignment changed our operating and reportable segments such that our historic North American management and franchising segment has been combined with operations in Latin America to form the Americas management and franchising operating and reporting segment. The remaining components of our former International management and franchising reporting segment have been broken out to form two new operating and reporting segments, Southeast Asia, as well as China, Australia, South Korea and Japan ("ASPAC") management and franchising and Europe, Africa, the Middle East and Southwest Asia ("EAME/SW Asia") management. These operating segments, together with our owned and leased hotels, form our four reportable segments, which we define as follows:

Х Owned and leased hotels, which consists of our owned and leased full service and select service hotels and, for purposes of segment Adjusted EBITDA, our pro rata share of the Adjusted EBITDA of our unconsolidated hospitality ventures, based on our ownership percentage of each venture.

Х Americas management and franchising, which consists of our management and franchising of properties located in the United States, Latin America, Canada and the Caribbean.

Х ASPAC management and franchising, which consists of our management and franchising of properties located in Southeast Asia, as well as China, Australia, South Korea and Japan.

Х EAME/SW Asia management, which consists of our management of properties located primarily in Europe, Africa, the Middle East and India as well as countries along the Persian Gulf and the Arabian Sea.

As part of our realignment, costs incurred in our global development efforts, which were previously aggregated in corporate and other have been allocated to the operating and reporting segment to which they relate. The results of our vacation ownership business, Hyatt co-branded credit card and unallocated corporate overhead continue to be reported within corporate and other.

The Company is furnishing under Item 7.01 of this Current Report on Form 8-K the Investor Fact Book dated February 2013 attached hereto as Exhibit 99.1 (the "Investor Fact Book") and posted on www.investors.hyatt.com to provide investors with certain unaudited historical financial information that has been recast to reflect our new reporting segments. The unaudited historical segment financial information included in the Investor Fact Book, when viewed on a consolidated basis, is as reported in the most recent periodic report in which the respective period was presented.

The unaudited historical financial information in the Investor Fact Book is not intended as a substitute for the recast segment information within the footnotes to the financial statements that will be reported in the Company's Form 10-K for the fiscal year ended December 31, 2012 and earnings release for the fourth quarter of fiscal year 2012. Although the Company currently expects that such recast segment data will be consistent with the unaudited financial information presented in the Investor Fact Book, the Company cannot assure you that differences will not arise between the unaudited financial information included in the Investor Fact Book and the recast segment information included within the audited financial statements to be presented in the Company's Form 10-K for the fiscal year ended December 31, 2012 and earnings release for the fourth quarter of fiscal year 2012. The Company's management and its independent public accountants will continue to perform and complete various procedures in connection with the Company's fiscal year 2012 annual reporting processes. These ongoing procedures with respect to the recast audited segment information within the footnotes to the financial statements may result in differences from the unaudited financial information set forth in the Investor Fact Book, and such differences may be material.
