NEW YORK ( TheStreet) -- There are now 155 undercapitalized institutions on the TheStreet's Bank Watch List, which is two more than last quarter, despite 11 banks being shuttered by regulators in the meantime. Based on a set of preliminary fourth-quarter regulatory data supplied by HighlineFI for the nation's banks and savings and loan associations -- and factoring-in the 11 bank and thrift failures since TheStreet's final third-quarter Watch List was published on Nov. 16 -- 155 institutions were undercapitalized at year-end, according to the regulatory guidelines that apply to most institutions.

Most banks and thrifts need to maintain Tier 1 leverage, Tier 1 risk-based and total risk-based capital ratios of at least 5%, 6% and 10% to be considered well-capitalized under regulatory guidelines. Some trust banks carry lower capital requirements. The ratios need to be at least 4%, 4% and 8% for most to be considered adequately capitalized. One banks on the preliminary fourth-quarter watch list was actually negatively capitalized as of Dec. 30. New City Bank of Chicago's Tier 1 leverage ratio fell to -2.38%, after the bank posted a fourth-quarter net loss of $5.2 million. U.S. Century Bank of Doral, Fla., is the largest institution on the preliminary fourth-quarter watch list, with $1.3 billion in total assets as of Dec. 30. The bank slipped from well capitalized to adequately capitalized in the fourth quarter of 2010, when it posted a $52 million net loss, as it set aside reserves, mainly for nonperforming commercial real estate and development loans, and saw its total risk-based capital ratio fall below 10.00%. The bank slipped to undercapitalized in the third quarter. Total losses for 2011 were $79 million, and the bank's nonperforming assets ratio was a very high 21.58% as of Dec. 30, according to HighlineFI.
