Foster + Partners made a loss of 拢15m in 2008 following a goodwill writedown of 拢15.5m.

The figure is the first slice of a total 拢310m writedown, which will happen over 20 years after the deal last year in which private equity group 3i took a 40% stake of the business for an undisclosed sum.

The sum is the difference between the value of the group鈥檚 assets and the transaction price. Mouzhan Majidi, chief executive, said the writedown was preferable to leaving it on the books or revaluing the company every year.

In addition to the cash injection from 3i, the architect also broadened its shareholder base and restructured its management team.

In the first results since the deal, turnover to 30 April 2008 grew 60% from 拢90m to 拢142.4m as a result of the company's global push. The pay of the highest-paid director fell 57% from 拢2.9m to 拢1.2m.

The contribution from the Middle East looks set to overtake the UK next year. It rose 51% from 拢17.9m to 拢27.1m; turnover in the UK was up 19% from 拢23.9m to 拢28.5m. The biggest slice came from Europe, where turnover grew 50% from 拢30.4m to 拢45.6m.

Majidi said: 鈥淲e have projects under way in India, Vietnam, Korea, Hungary and Bulgaria.鈥
