(“First South”). Pursuant to the Merger Agreement, on November 1, 2017, First South merged with and into the Company, with the Company as the surviving corporation. Immediately thereafter, First South Bank, a wholly owned subsidiary of First South, merged with and into CresCom Bank, a wholly owned subsidiary of the Company, with CresCom Bank as the surviving bank. CresCom Bank will operate the former offices of First South Bank under the name “First South Bank” until the data processing system conversion, which is currently expected to occur in March 2018.

Forward-Looking Statements

Certain statements in this Form 8-K contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, such as statements relating to future plans and expectations, and are thus prospective. Such forward-looking statements include, but are not limited to, statements with respect to plans, objectives, expectations and intentions and other statements that are not historical facts, and other statements identified by words such as “believes,” “expects,” “anticipates,” “estimates,” “intends,” “plans,” “targets,” and “projects,” as well as similar expressions. Such statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from future results expressed or implied by such forward-looking statements. Although the parties making such statements believe that the assumptions underlying the forward-looking statements are reasonable, any of the assumptions could prove to be inaccurate. Therefore, the Company provides no assurance that the results contemplated in the forward-looking statements will be realized. The inclusion of this forward-looking information should not be construed as a representation by the Company or any other person that the future events, plans, or expectations contemplated will be achieved.
