Jack C. Salzwedel, president and chief operating officer of American Family Insurance, said it remains to be seen whether the industry will "take [the revised model] seriously and increase rates."

Mr. Salzwedel said homeowners insurance is currently "not priced as it should be."

Liam E. McGee, chairman, president and CEO of The Hartford, added the company was "still not where we should be in homeowners."

One insurance executive at the forum said the new model could have a "whiplash effect" on some insurers—many who have moved away from the coast to avoid risk only to now find out the benefit of writing inland as opposed to on the coast may not be as wide as was once thought.

Lessons were learned from Hurricane Ike in 2008, which traveled inland after striking the Texas coast to cause billions of dollars in insured losses to other states. The storm's aftermath was enough to cause $1.255 billion in losses in Ohio and become the state's costliest natural disaster.

Late last year, Standard & Poor's said it would need to have a discussion with a company if the new model increased the company's probable maximum losses (PMLs). Taoufik Gharib, director and reinsurance specialist for S&P, said it is too early to predict the impact of the new model, but PMLs could decrease for coastal areas like Florida and increase in other areas.

Reinsurance broker Towers Watson recently said many reinsurers were pushing for rate increases at Jan. 1 because of the higher expected loss estimates as a result of the revised RMS model.

"More than a few buyers have purchased additional limits in anticipation of increased RMS loss estimates," said John DeMartini, leader of Towers Watson's Catastrophe Risk Management practice and the U.S. Property Reinsurance specialty practice.

The broker predicted insurers will run the model through their property portfolios and may see the impacts on their reinsurance programs beginning with July 1 renewals.
