Health insurer Cigna Corp. (NYSE: CI) reported a plunge of 80% in first-quarter profit this morning. The results were dragged down by deep charges related to its reinsurance business and litigation.

For the quarter, Cigna said that its profit dropped to $58 million, or 21 cents per share, compared with $289 million, or 98 cents, reported in the same period a year ago. Excluding one-time items, the insurer's earnings numbers would have come at 94 cents per share, one cent below the average estimate of analysts, according to Thomson Financial .
Looking at revenue, Cigna posted a rise of 4.5% in the quarter on a year-over-year basis. Analysts had been expecting to see revenue of $4.55 billion, while the actual number was slightly higher, at $4.57 billion. The company said that the number of clients who joined its health plans jumped 5.5% to 10.4 million.
