The Northern Ireland timber importers and builders merchants J.P. Corry has reported pre-tax profits of £613,000 sterling for the year to the end of March 1997. That compares with a loss of £1.1 million the previous year. Turnover rose slightly to £27.2 million. The company has undergone significant restructuring and redevelopment since April 1996, when a group of new investors, led by Mr Ansley Tolland, took control through a £7.1 million investment package.
