Closing is expected to take place on July 12, 2013. The registered public offering consisted of 60,000,000 Series B shares, constituting an offer size of approximately U.S.$185.7 million, excluding options granted to the underwriters to purchase additional Series B shares. The international offering, in the United States and outside Mexico, consisted of 36,000,000 Series B shares, directly or in the form of ADSs, or 60% of the Series B shares offered. The Mexican offering consisted of 24,000,000 Series B shares, or 40% of the Series B shares offered. The underwriters have a 30-day option to purchase an additional 9,000,000 Series B shares (equivalent to approximately U.S.$27.8 million). Of this total, 5,400,000 Series B shares were allocated to the international underwriters, and 3,600,000 Series B shares were allocated to the Mexican underwriters. The options may be exercised on a coordinated but independent basis among the international underwriters and the Mexican underwriters. The Series B shares being sold, including those subject to this option, total 69 million Series B shares and represent approximately 17.25% of OMA's capital stock. All of the Series B shares and ADSs will be sold by Aeroinvest, which will receive all the proceeds of the offering. OMA will not receive any proceeds from the offering, and its total number of outstanding Series B shares will not change as a result of the offering. ICA expects to retain a significant participation and the controlling interest in OMA through its ownership of OMA's Series BB shares.
