Nevada Security Bank had been assigned an E-minus (Very Weak) financial strength rating back in September by

Weiss Ratings

, formerly

TheStreet Ratings

. That rating was based on June 2009 financial reports showing that the bank was no longer

well capitalized

after a second quarter loss of $21 million.

Losses continued over subsequent quarters, and at March 31, the institution was critically undercapitalized with a tier 1 leverage ratio of 2.16% and a total risk-based capital ratio of 4.11%. These ratios need to be at least 5% and 10% for most banks to be considered well capitalized. Nonperforming assets comprised 16.33% of total assets as of March 31.
