FDIC Honored IBC Bank and VP Annette Alonzo for Educating Youth

LAREDO, Texas -- International Bancshares Corporation (NASDAQ: IBOC), the parent company of IBC Bank and Vice President Annette Alonzo of IBC - Port Lavaca, were acknowledged by the Federal Deposit Insurance Corporation (FDIC) on Tuesday for their dedication to educating youth on financial literacy and the importance of money management. Alonzo is one of only two recipients being recognized this year with the “Outstanding Money Smart Partner” award in the FDIC Dallas region, which is comprised of eight states.

“At IBC, we pride ourselves on having employees who strive to go above and beyond by “doing more,” not only when providing sound financial advice but also when giving back to the communities we call home,” IBC Chairman and CEO Dennis E. Nixon said. “In times such as these, smart money management is very important and we are committed to ensuring that children learn sensible financial habits at an early age. Annette’s work in financial literacy epitomizes our bank’s motto, We Do More, and we are proud to say that her contribution and those of our employees add to the strength of our communities.”

FDIC Community Affairs Officer Eloy Villafranca and Jesse King presented a certificate and memento to both Dennis E. Nixon, who accepted it on behalf of IBC Bank, and Annette Alonzo for her leadership while implementing FDIC’s Money Smart program across all IBC markets. Since 2005, IBC employees – led by Annette Alonzo – have actively participated in Money Smart financial literacy education programs at area schools. Annette has helped leverage the bank’s core area of expertise and has truly made an impact on filling the financial education void that exists today.

The ceremony preceded IBC’s Money Buzz lesson for 4th grade students at MacDonnell Elementary which was held to celebrate Teach the Children to Save Day and Financial Literacy Month. The Money Buzz is a one-hour lesson that teaches children the value of currency and the importance of saving and will be taught by IBC employees to more than 1,000 kids throughout Texas and Oklahoma in the next weeks.

The acknowledgement by the FDIC adds to the list of accolades IBC Bank and its employees have received over the past couple of years for their work within the community. In 2008, IBC Chairman and CEO Dennis E. Nixon received the International Citizen of the Year Award from the World Affairs Council of San Antonio, and the bank was also honored with the Good Neighbor Award from the U.S. - Mexico Chamber of Commerce. The bank also is a past recipient of the Texas Bankers Association’s Cornerstone Award for community support as well as the Governor’s Volunteer Award.
