The deal between Ultra Electronics Forensic Technology Inc. and federal prosecutors has been approved by the Superior Court of Quebec.

Only a handful of SNC-Lavalin rivals or their subsidiaries have received deferred prosecution agreements, according to a Canadian Press analysis of figures on corporate settlements from a pair of databases.

The CEO of SNC-Lavalin says about 75 per cent of the company's rivals have concluded deferred prosecution agreements in their host countries and are free to work in Canada.
