Paul Hastings, McDermott Will & Emery and King & Spalding each posted global revenues rises in 2013, according to financial results released by the US-headquartered law firms this week.

Paul Hastings saw a 3.6% increase in global revenues from $908m (£544m) to $941m (£564m) last year, with profit per partner rising by 4.6% to $2.18m (£1.3m) and revenue per lawyer up 5% to $1.06m (£635,000).

Meanwhile, Atlanta native King & Spalding posted a fourth successive year of revenue growth, with takings up to $861.4m (£516.1m) in 2013, a 4% gain.

Profits per equity partner (PEP) was up 8% to $2.14m (£1.28m), the first time the firm has breached the two-million-dollar mark, and a 49% rise on 2009 PEP of $1.44m (£863,000).

The firm has also increased revenue by 27.1% since 2009.

Separately, McDermott has seen a 3.5% increase in gross revenue to $880.8m (£528.2m), with net income standing at $296.8m (£178m), a 7% jump on 2012. The income figure also means the firm's profit margin for 2013 stood at 33.7%.

Profits per partner were up 5.9% to $1.55m (£929,500), while revenue per lawyer saw a smaller 3.8% climb to $862,645 (£517,000).

The trio joins a number of US heavyweights to have posted strong financials for 2013, including Dechert, Sidley Austin, Vinson & Elkins, Shearman & Sterling and Latham & Watkins.

So far, the only major casualty of the reporting season has been Bingham McCutchen, which saw global revenue fall by $110m (£65.8m) last year, a 13% drop.

As reported by Legal Week last week, the firm has asked members of its global partnership – including some in its global management committee – to take a minimum pay "haircut" of 10% in addition to any drop in individual performance-based remuneration.
