Hogan Lovells' international partnership saw capital contributions from members increase by more than £10m during the financial year ending 30 April 2011, according to the firm's limited liability partnership (LLP) accounts.

The accounts, filed with Companies House last week, cover the activities of legacy Lovells outside North and South America – now Hogan Lovells International.

They show capital introduced by members during the year totalled £12.9m, compared with £2.1m the previous year. The increase, understood to be the result of the promotion of salaried partners into the equity as well as capital from new joiners, took members' capital in the business to £42.6m – £9.5m more than the previous year.

The accounts, which confirm the revenue of the International LLP at £582.2m compared with £520.4m the previous year, also show the impact of the merger between legacy Lovells and legacy Hogan & Hartson on fee earner numbers in the international LLP.

Lawyer count dropped by nearly a third due to transfers to other partnerships within the firm, with fee earner numbers in the international LLP falling from 645 to 449, while support staff numbers fell from 549 to 429. The firm said the drop was explained by the closure of legacy Lovells' Chicago office and the associated transfer of New York lawyers into Hogan's US partnership, combined with a decision to create a separate French LLP subsidiary in Paris to house all of its French operations.

Fee earner headcount for the international partnership as a whole – which includes the Paris, Hong Kong, Japan, Italy, Poland, Czech Republic and Alicante offices as well as those sitting within the LLP, such as the UK – decreased from 1521 to 1473. Total staff costs increased from £225.3m to £238.4m over the period.

The firm gained £5.8m during 2010-11 as a result of transactions relating to the closure of legacy Lovells' Chicago office and the transfer of most of the assets used in New York and Chicago to Hogan & Hartson. This compares with an estimated loss of £18.5m the previous year.

Operating profit, meanwhile, increased from £164.8m in 2009-10 to £211m in the most recent financial year – an increase of nearly 29%. Hogan Lovells International had £46.1m of net cash at 30 April 2011, compared with £14.3m the previous year, with bank facilities in place of £60m. Profit available for division among equity partners rose from £126.8m to £184m.

The accounts also show the firm's key management team took home £8.1m between them, compared with £8.3m in 2010.

A spokesperson commented: "Our underlying business performance over the year has been encouraging, exhibiting the benefits of the Hogan Lovells combination, the continued demonstration of the strength of our client work across our practice areas, industry sectors, and regions, and the positive effects of tight cost control in the current economic conditions."
