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.
