Proskauer Rose’s London office owed the US partnership a total of £13.7m at the end of its 2011-12 financial year, according to UK limited liability partnership (LLP) accounts recently filed with Companies House.

The loan was driven by lateral recruitment, with Proskauer making seven partner hires in London over a 12-month financial period ending on 31 October 2011, as well as its move to new City premises in 10 Bishops Square.
