Shareholders' Equity [Abstract]

Shareholders' Equity

Note 15 – Shareholders' Equity

Trustmark and TNB are subject to minimum capital requirements, which are administered by various federal regulatory agencies.  These capital requirements, as defined by federal guidelines, involve quantitative and qualitative measures of assets, liabilities and certain off-balance sheet instruments.  Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional, discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements of Trustmark and TNB.  As of March 31, 2012, Trustmark and TNB have exceeded all of the minimum capital standards for the parent company and its primary banking subsidiary as established by regulatory requirements.  In addition, TNB has met applicable regulatory guidelines to be considered well-capitalized at March 31, 2012.  To be categorized in this manner, TNB must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the accompanying table.  There are no significant conditions or events that have occurred since March 31, 2012, which Management believes have affected TNB's present classification.

Trustmark's and TNB's actual regulatory capital amounts and ratios are presented in the table below ($ in thousands):
