Our Board of Directors and executive management team focus on Adjusted EBITDA as a key performance and compensation measure both on a segment and on a consolidated basis. Adjusted EBITDA assists us in comparing our performance over various reporting periods on a consistent basis because it removes from our operating results the impact of items that do not reflect our core operating performance both on a segment and on a consolidated basis. Our president and chief executive officer, who is our chief operating decision maker, also evaluates the performance of each of our reportable segments and determines how to allocate resources to those segments, in significant part, by assessing the Adjusted EBITDA of each segment. In addition, the compensation committee of our Board of Directors determines the annual variable compensation for certain members of our management based in part on consolidated Adjusted EBITDA, segment Adjusted EBITDA or some combination of both.We believe Adjusted EBITDA is useful to investors because it provides investors the same information that we use internally for purposes of assessing our operating performance and making selected compensation decisions. Adjusted EBITDA is not a substitute for net income attributable to Hyatt Hotels Corporation, net income, cash flows from operating activities or any other measure prescribed by GAAP. There are limitations to using non-GAAP measures such as Adjusted EBITDA. Although we believe that Adjusted EBITDA can make an evaluation of our operating performance more consistent because it removes items that do not reflect our core operations, other companies in our industry may define Adjusted EBITDA differently than we do. As a result, it may be difficult to use Adjusted EBITDA or similarly named non-GAAP measures that other companies may use to compare the performance of those companies to our performance. Because of these limitations, Adjusted EBITDA should not be considered as a measure of the income generated by our business or discretionary cash available to us to invest in the growth of our business. Our management compensates for these limitations by reference to our GAAP results and using Adjusted EBITDA supplementally.
