CMS Cameron McKenna has posted a revenue dip of 6.6% for the 2012-13 financial year, alongside a 12.5% drop in profit.

The firm's limited liability partnership (LLP) accounts, filed with Companies House, show that turnover fell from £227.6m in 2011-12 to £212.6m.

When deducting the firm's share of turnover from its Moscow joint venture with CMS' German and French member firms, group turnover fell to £205.7m, down on the previous year's equivalent of £219.8m.

Operating profit tumbled from £54.6m to £47.7m, marking a 12.5% decrease, while profit available for division among Camerons' members also fell, by 4% from £39.4m to £37.9m.

The average member count across the firm fell to 94 from 105. Overall staff numbers also fell, with fee-earner headcount dropping from 904 to 875 and support staff from 475 to 455. Consolidated salary figures decreased from £60.5m to £59.8m.

The firm last year reported a 5.1% rise in revenues across CMS' network of 10 law firms but refused to disclose figures relating only to the UK part of the business.

The LLPs also show that the UK firm's top earner in 2012-13 took home £1.11m, including an early retirement provision of £533,000. Last year, the highest paid member earned £1.15m with a provision of £546,000.

The filing shows that cash at bank and in hand fell from £13.3m to £8m, while the firm's cash outflow was £4.26m, compared with the previous year when there was an inflow of £20.9m.

During the year, employees and partners at the firm contributed more than 17,000 hours of working time to community and charitable activities.
