IBERIABANK history

Trotter joined the bank in January 1947, serving as its managing officer for 30 years.

By then its name had been changed to Iberia Savings & Loan Association (ISLA), and its assets had reached $294.6 million, up almost $100 million over the assets it had held in 1978.

State restrictions on thrifts opening branches in more than one parish were dropped in 1985, allowing ISLA to open offices in Morgan City and Franklin, both in St Mary Parish, to the south of Iberia Parish.

ISLA became Iberia Savings Bank (ISB) in 1988, and expansion continued the following year into Lafayette, Louisiana with the acquisition of Acadia Savings & Loan.

By 1992, it also appeared that additional regulatory changes would soon permit Louisiana savings and loan banks to reorganize and convert to state-chartered commercial banks.

Bank President Larrey Mouton prepared the company for this transition by forming the holding company ISB Financial Corporation and releasing an IPO on April 13, 1995.

At the close of 1996, bolstered by these acquisitions, ISB Financial had total assets of $929.3 million and deposits of $760.3 million.

With its 1997 renaming and conversion into a Louisiana-chartered, full-service commercial bank, IBERIABANK set out both to tap into new Louisiana markets and to increase and diversify its services.

After First Commerce was bought out by Bank One in 1998, he was named president and CEO of Bank One's Louisiana's New Orleans region.

In 1999, former Bank One executive Daryl Byrd took over as CEO, ushering in a period of rapid growth for the bank.

In fact, its last vestiges may have been expunged in 2000, when ISB Financial Corporation removed the 'S' for Savings in its new name, IBERIABANK Corporation.

Byrd claimed that these restructuring changes would result in savings of about $2 million starting in 2001.
