Bancorp, Inc. of Binghamton slated to close in the fourth quarter of this year. This merger, currently pending regulatory and stockholder approval, will create a financial services holding company with pro forma assets of $4.8 billion and three direct operating subsidiaries, including community banks in New York and Pennsylvania and a financial services company. O BSB Bank & Trust and NBT Bank, the companies' principal banking subsidiaries, will be combined to create the New York bank. O NBT Bancorp recently acquired LA Bank and Pioneer American Bank.

Forsythe will serve as the chairman, president and chief executive officer of the combined company. He stated, "This merger is a great strategic fit for our companies. We offer similar products and services, and the markets we serve are contiguous. By far, the most important common ground we have is our shared community banking philosophy. Bringing our successful companies together will create a solid foundation that will allow us to expand the financial service options we offer and continue to deliver high quality service to existing and new customers."
