Bermuda-based reinsurer PX Re reported an increase in retentions in the second quarter.

Gross written premiums (GWP) increased 59% quarter-on-quarter and 7% half-on-half but net written premiums increased by a whopping 180% quarter-on-quarter and 22% half-on-half, indicating the company was retaining more risk during the periods.

The operation greatly increased its catastrophe and net risk excess writing, which hit net premiums of $51m (£32m) in the second quarter from $23m (£14m) the year before.

But losses and expenses also increased in the quarter, by 116% to $72m (£45m) from $33m (£21m). Measured across the six months ended 30 June, losses and expenses increased 85% to $138m (£86m) from $75m (£47m). The combined ratio deteriorated to 81% in the second quarter from 65% the year before and to 76% in the six months from 64%.

PX Re also increased prior-year loss reserves by $18.1m (£11m) in the second quarter, focused mainly on aerospace and exited lines.

Total revenues increased by 70% in the second quarter, to $94m (£59m) from $55m (£34m) in the same period last year.
