These revisions to the financial results previously announced on February 13, 2008 primarily relate to:

1) The establishment of reserves as a result of ongoing tax audits related to the Company's former European prepaid services operations. Although no assessment of taxation has been received to date specific to these matters, after evaluation of tax auditor inquiries, further internal investigation, review of available documentation and consultation with local tax advisors, management concluded it was appropriate to accrue an obligation for a possible assessment of value added and payroll taxes; and

2) The completion of our accounting for income taxes, including the impact of FIN No. 48, "Accounting for Uncertainty in Income Taxes."

We believe our accruals for value added, payroll and income taxes appropriately reflect our potential obligations (including related penalties and interest). Our financial results, after giving effect to these accruals, will be reflected in detail in our 2007 Annual Report on Form 10-K to be filed with the Securities and Exchange Commission on March 17, 2008.
