[7] In 1988, Ronald E. Hermance, Jr. was hired at Hudson City Savings as senior executive vice president and chief operating officer.

In February 1999, the bank initiated a plan of reorganization as a wholly owned subsidiary of Hudson City Bancorp, Inc.

[8] On June 8, 2005, the company made the largest public stock offering in the history of the United States banking industry, represented by Thacher Proffitt.

The conversion from the mutual holding company structure made Hudson City Bancorp a fully publicly held entity.

[7] On February 14, 2007, the company was added to the S&P 500 Index by Standard & Poor's, where it replaced American Power Conversion Corporation[7] During the subprime mortgage crisis, Hudson City was cited as an example of good management.

They continued to require a good credit score and down payments of 10 to 20 percent, and avoided "exotic mortgages" allowing no income verification and/or no down-payment.

While initially better off, the other large banks offloaded their bad loans to the government, leaving Hudson City with more debt than their competitors.

After the housing crisis, the rules changed raising the conforming limit, which enabled the high credit quality jumbo loans to refinance to the lower rate available to GSE-purchased mortgages.

[13] A loss of high-quality borrowers, an inability to issue new mortgages at reasonable rates, and a portfolio of non-performing loans encouraged the bank to accept a buy-out.

On September 12, 2014, after the death of Ronald Hermance, Hudson City Bancorp appointed Denis J. Salamone as chief executive officer in accordance with the company's succession plan.

[14] In September 2015 the corporation agreed to a settlement of $5,500,000 for mortgage lending practices which discriminated against largely Black and Latin-American neighborhoods.

The Federal Reserve finally approved the acquisition in September 2015, and on November 1, 2015, Hudson City Bancorp became an M&T subsidiary.
