Three publicly traded banks that accept deposits in Rhode Island say they have applied for infusions of capital under a new U.S. Treasury program.

They include Bank Rhode Island, Webster Bank and Bank of America.

Some others — including Newport Federal Savings Bank and Washington Trust Co. — said they did not apply and do not need the money because they have enough capital already.

Last Friday was the deadline for publicly traded banking companies to voluntarily seek infusions of capital. The infusions, which are investments of taxpayer money into banks by the U.S. Treasury, are available through the Treasury’s Troubled Asset Relief Program.

The program is part of federal bailout legislation recently approved by Congress and signed into law by President Bush.

In general, capital is the financial cushion a bank needs to help withstand losses, including on mortgages and other loans.

Overall, more than 60 banking institutions indicated they were eligible to receive more than $173 billion in aid through the program, according to a Wall Street Journal report, citing figures from Keefe, Bruyette & Woods, a New York advisory firm. (The Treasury has not disclosed to the public the names of applicants.)

The following is a summary:

•Webster: Webster Financial Corp., of Waterbury, Conn., the holding company for Webster Bank, said it has received preliminary approval for $400 million in new capital through the program.

James C. Smith, Webster’s chairman and chief executive officer, said in a statement, “Participating in the program is the right thing to do. While Webster is already well capitalized, we support the Treasury’s objective to ensure that sufficient credit is available for the borrowing needs of consumers and businesses.”

Webster said it plans to use the money to issue loans in the four states it serves — Rhode Island, Massachusetts, Connecticut and New York, said spokesman Ed Steadham. The additional capital will also position Webster to pursue possible acquisitions of other banks, the company said in a statement.

•Bank Rhode Island: Bancorp Rhode Island Inc., of Providence, parent of Bank Rhode Island, said it is qualified to receive up to $30 million in additional capital.

Merrill W. Sherman, president and CEO of Bancorp Rhode Island, said in a statement, “After careful review, we believe this program, as it stands today, would provide us with an opportunity to build on our third-quarter momentum and further strengthen our lending capabilities for customers.”

Sherman added, “Bancorp Rhode Island has had a longstanding commitment to the community and the customers which it serves. We believe that it is in the best interest of all of our constituents — shareholders, customers and community — to develop a ‘super-capitalized’ balance sheet, which will support increased lending capacity over the coming years.”

•Newport Federal: Newport Bancorp Inc., of Newport, parent company of Newport Federal Savings Bank, has not applied for bailout funds “because we don’t need the capital, basically,” said Bruce Walsh, chief financial officer.

“We’re in good shape,” Walsh said.

•Washington Trust: Washington Trust Bancorp Inc., of Westerly, parent of Washington Trust Co., raised $47 million in capital by issuing common stock last month and has not applied for federal aid because it does not need it, the company said.

John C. Warren, chairman and CEO of Washington Trust, said in a statement, “We have evaluated the funding opportunity available through the [Treasury program] and concluded that reliance on our existing capital position and the utilization of funding available through alternative channels is in the best long-term interests of our shareholders.”

Warren added, “Our strong capital position and financial performance have enabled us to continue to serve our markets and meet the lending needs of our customers throughout this difficult financial period.”

•Bank of America: Bank of America Corp., of Charlotte, N.C., said last month that it has issued securities to the Treasury in exchange for a capital infusion of $15 billion.

•Others: Some other banks accept deposits in Rhode Island but are not publicly traded and therefore did not qualify for the program.

For example, Citizens Bank is part of Citizens Financial Group of Providence, which, in turn, is a subsidiary of Royal Bank of Scotland, which is based in the United Kingdom and is publicly traded.

Because Citizens is not, itself, a publicly traded company, it was not eligible for the program and, so, did not apply, spokesman Mike Jones said.
