Verisk Analytics, Inc.

The company's Insurance Services Office (ISO) subsidiary was created in 1971 through the consolidation of various property/casualty insurance bureaus.

In 2009, Verisk completed its IPO and became a publicly traded company. The firm did not raise any funds for itself in the IPO, which was designed to provide an opportunity for the firm's casualty and property insurer owners to sell some or all of their holdings and to provide a market price for those retaining their shares. The 2009 IPO was priced at $22 per share for 85.25 million shares owned by its shareholders, including American International Group, The Hartford and Travelers, making it the largest since the 2008 IPO for Visa Inc. In an action described by investment research company Morningstar as a "vote of confidence" in Verisk, Berkshire Hathaway was the only company among the firm's largest shareholders that did not sell any of its stock in the October 2009 IPO.
