Park believes that an evaluation of its ongoing operations would be difficult if the disclosure of its operating results were limited to accounting principles generally accepted in the United States of America (“GAAP”) financial measures, which include special items, such as a charge related to storm damage, a non-cash tax charge and a reduction in uncertain tax positions. Accordingly, in addition to disclosing its operating results determined in accordance with GAAP, Park discloses non-GAAP measures, including Adjusted EBITDA, and operating results that exclude special items in order to assist its shareholders and other readers in assessing the Company’s operating performance, since the Company’s ongoing, normal business operations do not include such special items. The detailed operating information presented below includes a reconciliation of the non-GAAP operating results before special items to earnings determined in accordance with GAAP and a reconciliation of GAAP pre-tax earnings to Adjusted EBITDA. Such non-GAAP financial measures are provided to supplement the results provided in accordance with GAAP.
