MEXICO CITY - Mexico's top building company ICA said on Monday it could sell up to 150 million shares in Mexico and the United States to finance projects in infrastructure and housing.

ICA said it could sell up to 105 million CPO shares and also 45 million shares. It said one CPO share is equivalent to one share.

ICA will sell most of the shares to international investors, according to a prospectus filed with the Mexican stock exchange.

Shares in ICA fell 3.3 percent to 22.86 pesos and its New York-traded stock dropped 4.08 percent to $6.82.

The plan needs to be approved by shareholders at a meeting next week.
