"Our business is solid and has met expectations," said chief financial officer Mark Dance. "However we experienced some unanticipated non-cash expenses."

Unanticipated expenses of 1m (US$1.9m) after tax due to revaluation of Canadian dollar net assets, consolidating some US operations and lease exit costs of 322,000 will push the firm from an anticipated earning per share of $0.01 to $0.05 to a loss per share of $0.01 to $0.03 on revenues anticipated to be $156m for the quarter.

The full figures will be released on 4 August.

Dance added that the firm was confident of reaching its target of 10% revenue growth for the year.
