I want to know the answer to the following question:
What publicly traded bank, also the second largest in Connecticut, is based in New Haven?
All the background I'm provided with is that "The Southern New England Telephone Company (SNET) began operations in the city as the District Telephone Company of New Haven in 1878; the company remains headquartered in New Haven as a subsidiary of AT&T Inc., now doing business as AT&T Connecticut, and provides telephone service for all but two municipalities in Connecticut.". Is that enough to answer the question?
