The accompanying consolidated balance sheets and statements of capitalization of Aqua America, Inc. and subsidiaries (the “Company”) at March 31, 2016, the consolidated statements of net income and comprehensive income for the three months ended March 31, 2016 and 2015 the consolidated statements of cash flow for the three months ended March 31, 2016 and 2015, and the consolidated statement of equity for the three months ended March 31, 2016 are unaudited, but reflect all adjustments, consisting of only normal recurring accruals, which are, in the opinion of management, necessary to present fairly the consolidated financial position, the consolidated changes in equity, the consolidated results of operations, and the consolidated cash flow for the periods presented.  Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures and notes normally provided in annual financial statements and, therefore, should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.  The results of operations for interim periods may not be indicative of the results that may be expected for the entire year.  The December 31, 2015 consolidated balance sheet data presented herein was derived from the Company’s December 31, 2015 audited consolidated financial statements, but does not include all disclosures and notes normally provided in annual financial statements.  Certain prior period amounts have been reclassified, including debt issuance costs (see Note 15 - Recent Accounting Pronouncements), to conform to the current period presentation.
