Note 5 — Stock Options On April 1, 2005, the Board of Directors adopted the 2005 International Bancshares Corporation Stock Option Plan (the “2005 Plan”). Effective May 19, 2008, the 2005 Plan was amended to increase the number of shares available for stock option grants under the 2005 Plan by 300,000 shares. The 2005 Plan replaced the 1996 International Bancshares Corporation Key Contributor Stock Option Plan (the “1996 Plan”). Under the 2005 Plan, both qualified incentive stock options (“ISOs”) and non-qualified stock options (“NQSOs”) may be granted. Options granted may be exercisable for a period of up to 10 years from the date of grant, excluding ISOs granted to 10% shareholders, which may be exercisable for a period of up to only five years. As of September 30, 2011, 230,398 shares were available for future grants under the 2005 Plan. A summary of option activity under the stock option plans for the nine months ended September 30, 2011 is as follows:
