Item 7.01 Regulation FD Disclosure.

The Colonial BancGroup, Inc. (“BancGroup”) is furnishing this Current Report on Form 8-K in connection with its Board of Directors’ July 19, 2006 resolution authorizing certain BancGroup Officers (“Authorized Officers”) to purchase the number of shares of BancGroup Common Stock issued under BancGroup’s various equity-based compensation and incentive plans (the “Plans”) during 2006, and the number of shares which are likely to be issued under the Plans through the termination date of this authorization, not to exceed $50,000,000 (the “Program”). The Program is expected to be accomplished in one or more block purchases, on the open market or otherwise at such price and on such other terms as the Authorized Officers deem to be in the best interest of BancGroup. It is anticipated that the Program will utilize the safe harbor provided by Rule 10b-18 promulgated under the Securities Exchange Act of 1934, as amended. In the event the Authorized Officers determine that circumstances arise, including but not limited to, changes in market conditions, an unexpected need for capital, or any other events, then the Authorized Officers are authorized to elect on behalf of BancGroup not to proceed with the Program. The authority granted by the Board of Directors shall terminate on July 19, 2008.

This release includes “forward-looking statements” within the meaning of the federal securities laws. Words such as “believes,” “estimates,” “plans,” “expects,” “should,” “may,” “might,” “outlook,” and “anticipates,” and similar expressions, as they relate to BancGroup including its subsidiaries or its management), are intended to identify forward-looking statements. The forward-looking statements in these reports are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in or implied by the statements. In addition to factors mentioned elsewhere in this report or previously disclosed in BancGroup’s SEC reports (accessible on the SEC’s website at www.sec.gov or on BancGroup’s website at www.colonialbank.com), the following factors among others, could cause actual results to differ materially from forward-looking statements and future results could differ materially from historical performance. These factors are not exclusive:

• deposit attrition, customer loss, or revenue loss in the ordinary course of business;

• increases in competitive pressure in the banking industry;

• costs or difficulties related to the integration of the businesses of BancGroup and institutions it acquires are greater than expected;

• the inability of BancGroup to realize elements of its strategic plans for 2006 and beyond;

• changes in the interest rate environment which expand or reduce margins or adversely affect critical estimates as applied and projected returns on investments;

• economic conditions affecting real estate values and transactions in BancGroup’s market and/or general economic conditions, either nationally or regionally, that are less favorable then expected;

• natural disasters in BancGroup’s primary market areas result in prolonged business disruption or materially impair the value of collateral securing loans;

• management’s assumptions and estimates underlying critical accounting policies prove to be inadequate or materially incorrect or are not borne out by subsequent events;

• strategies to manage interest rate risk may yield results other than those anticipated;

• changes which may occur in the regulatory environment;

• a significant rate of inflation (deflation);

• acts of terrorism or war; and

• changes in the securities markets.

Many of these factors are beyond BancGroup’s control. The reader is cautioned not to place undue reliance on any forward looking statements made by or on behalf of BancGroup. Any such statement speaks only as of the date the statement was made or as of such date that may be referenced within the statement. BancGroup does not undertake any obligation to update or revise any forward-looking statements.
