Imtech admits "possible irregularities" - FT.com Dutch infrastructure company Imtech will take a writedown of at least €100m based on "possible irregularities" in its Polish division. René van der Bruggen, chief executive, said the writedown will put the company in breach of its bank covenants and the company will probably cancel its dividend distribution for 2012. Imtech said it had postponed the publication of its 2012 annual figures until further notice while it carries out a review of the Polish division. The management of that division has been placed on non-active status pending the outcome of the review. Imtech has been embroiled in a testy back-and-forth with analysts since a report by ABN Amro several months ago charged the company's German division was having serious problems collecting revenues. Shares plunged 36 per cent to €12.48 in morning trading on the Amsterdam exchange.
