EXHIBIT 99.1 PRO FORMA FINANCIAL INFORMATION (UNAUDITED) The following Unaudited Pro Forma Condensed Combined Statement of Operations for the six months ended June 30, 2001 gives effect to the Company's March 1, 2001 acquisition (the "Acquisition") of Avis Group Holdings, Inc. ("Avis"), which has been accounted for under the purchase method of accounting. The Unaudited Pro Forma Condensed Combined Statement of Operations assumes the Acquisition occurred on January 1, 2001. The unaudited pro forma financial information is based on the historical consolidated financial statements of the Company and Avis under the assumptions and adjustments set forth in the accompanying explanatory notes. Since Avis was consolidated with the Company as of March 1, 2001, the results of operations of Avis between January 1, 2001 and February 28, 2001 were combined with the Company's results of operations to report the combined pro forma results of operations for the six month period ended June 30, 2001. All intercompany transactions were eliminated on a pro forma basis. In connection with the Acquisition, the Company retained ownership of Avis' Vehicle Management and Leasing business and its Wright Express business. The Company's parent, Cendant Corporation ("Cendant") retained ownership in Avis' other business, Avis Rent A Car ("ARAC"), through a dividend of this business from the Company to Cendant. As a result of the Acquisition, the Company and Cendant made payments totaling approximately $994 million, including payments of $937 million to Avis stockholders, direct expenses of $40 million related to the transaction and the net cash obligation of $17 million related to Avis stock options settled prior to consummation. The purchase price also included the fair value of CD common stock options exchanged with certain fully-vested Avis stock options. The Unaudited Pro Forma Condensed Combined Statement of Operations reflects interest expense on $600 million of the purchase price financed through loans from Cendant. The remaining amount was financed from existing cash and other intercompany loans which were immediately repaid at March 31, 2001. The unaudited pro forma financial information excludes any benefits that might result from the Acquisition due to synergies that may be derived or from the elimination of duplicate efforts. The Company's management believes that the assumptions used provide a reasonable basis on which to present the unaudited pro forma financial information. The Company has completed other acquisitions and dispositions which are not significant and, accordingly, have not been included in the accompanying unaudited pro forma financial information. The unaudited pro forma financial information may not be indicative of the results of operations that would have occurred if the Acquisition had been in effect on the dates indicated or which might be obtained in the future. The unaudited pro forma financial information should be read in conjunction with the historical consolidated financial statements and accompanying notes for the Company, Cendant and Avis. <Page> PHH CORPORATION AND SUBSIDIARIES UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 2001 (IN MILLIONS) <Table> <Caption> PRO FORMA ADJUSTMENTS HISTORICAL -------------------------- HISTORICAL AVIS DIVIDEND COMBINED PHH JAN 1-FEB 28, 2001 OF ARAC (A) ACQUISITION PRO FORMA ---------- ------------------ ----------- ----------- --------- REVENUES Service fees, net $ 525 $ 27 $ -- $ -- $ 552 Vehicle rental -- 366 (366) -- -- Fleet leasing 520 228 -- -- 748 Other 87 20 (20) (3) (b) 84 ---------- ------------------ ----------- ----------- --------- Net revenues 1,132 641 (386) (3) 1,384 EXPENSES Operating 361 174 (174) -- 361 Vehicle depreciation, lease charges and interest, net 422 350 (152) -- 620 Selling, general and administrative 69 115 (83) 6 (c) 107 Non-vehicle depreciation and amortization 35 23 (8) (1) (d) 49 Other charges 8 12 (11) -- 9 ---------- ------------------ ----------- ----------- --------- Total expenses 895 674 (428) 5 1,146 INCOME (LOSS) BEFORE INCOME TAXES 237 (33) 42 (8) 238 Provision (benefit) for income taxes 95 (10) 16 (3) (e) 98 ---------- ------------------ ----------- ----------- --------- INCOME (LOSS) BEFORE CUMULATIVE EFFECT OF ACCOUNTING CHANGE $ 142 $ (23) $ 26 $ (5) $ 140 ========== ================== =========== =========== ========= </Table> SEE ACCOMPANYING NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS. <Page> PHH CORPORATION AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 2001 (DOLLARS IN MILLIONS) (a) The dividend of ARAC to Cendant was assumed to occur on January 1, 2001 for purposes of preparing the Unaudited Pro Forma Condensed Combined Statement of Operations.
