We have expanded into insurance and mortgage insurance with operations around the globe.

See some of our milestones


We assess our performance by several criteria, including growth in book value per share, a major factor in the creation of shareholder value. Shareholders who invested in our recapitalization in 2001 and continue to hold the shares have seen the book value of their shares increase exponentially. Our credit ratings are a testament to our sustained superior track record and the strength of our operations.

A key driver of book value growth is return on equity (ROE). Net income ROE has averaged 14.6 percent per year for the past decade. Operating income ROE has averaged 12.8 percent over the past decade.
