New York-listed PartnerRe has estimated its exposure to collapsed energy giant Enron at approximately $49m (£33.8m) pre-tax, and $34m (£23.4m) after tax.
The company said the bulk of its exposures related to surety reinsurance contracts, while exposures to various liability reinsurance coverages and investment losses were not material.
It said at this point it could not accurately estimate the actual losses it might incur under its reinsurance contracts, since various contingencies could affect the amount and the timing of actual claims.
PartnerRe is rated A-plus (Superior) by ratings agency AM Best.
Enron exposure has hit several insurers, with exposure estimates of more than $4bn (£2.8m) from insurance companies.
According to AM Best, those with the highest exposure estimates so far include John Hancock Financial Services, with $320m (£220.5m), Aegon, with $300m (£206.7m) and Chubb, with $220m (£151.6m).
