Corporate Travel Management (ASX:CTD) has withdrawn its fiscal year revenue and earnings outlook, following a review of the UK group's financial statements by KPMG, according to a Friday filing with the Australian bourse.

KPMG identified areas of concern regarding the recognition of the UK group's concluded customer contracts and other revenue representing an aggregate transaction value of 400 million pounds sterling, the filing said.

Material restatements are required to reverse the revenue, and the company has started a review of the UK group's financial process and record keeping, the filing added.

The timing for the release of the company's results for the fiscal year is unknown, the company said.

It has obtained relief from the Australian Securities and Investments Commission to extend the deadline to lodge the financial statements until Dec. 31, which it does not expect to meet, the company added.
