Brit Insurance said it had successfully completed the individual capital adequacy standards (ICAS) pilot study with the FSA.
The company said it had received the FSA's indicative individual capital guidance (ICG), which it said it believed set its capital requirements at an appropriate level.
Brit Insurance chief executive Dane Douetil said: “We believe that Brit Insurance is one of the first insurance companies in the UK to have successfully completed the ICAS study with the FSA.
“We started building our own ICA capital model some two and a half years ago and have developed its parameters over this time.
“Brit has positioned itself as being at the forefront of risk knowledge and future capital requirement management, which we believe will be a source of competitive advantage in the future.”
