InsWeb, an online insurance comparison provider, has adopted a stockholder rights plan to help preserve the value of certain deferred tax assets of InsWeb generated by net operating losses and other tax benefits under Section 382 of the Internal Revenue Code.

InsWeb’s calculation of net operating losses and other tax benefits will be limited by Section 382 if an ownership change occurred.

The stockholder rights plan will be adopted to reduce the likelihood of an unintended ownership change occurring as a result of ordinary buying and selling of shares of InsWeb’s common stock.

After the stockholder rights plan became effective, any stockholder or group that acquires beneficial ownership of 4.9% or more of InsWeb’s outstanding securities without the approval of InsWeb’s board of directors will be subjected to significant dilution in its holdings

InsWeb said that its request for early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 was granted effective 16 November 2011 by the US Federal Trade Commission and the US Department of Justice.
