Massachusetts General Laws Part I. Administration of the Government (Ch. 1-182) Ch. 167, § 2J

A savings bank, co-operative bank or trust company, federal bank, out-of-state bank, foreign bank or limited purpose trust company may request that specific information in any application filed with the commissioner be treated as confidential. The following information shall be eligible for confidential treatment: (i) personal information, the release of which would constitute a clearly unwarranted invasion of privacy; (ii) commercial or financial information, the disclosure of which could result in substantial competitive harm to the submitter; and (iii) information, the disclosure of which could seriously affect the financial condition of any such bank. The commissioner may determine that certain information should be treated as confidential and withhold that information from the public file.

If any such bank requests confidential treatment for information that the commissioner determines is not eligible for confidential treatment, the commissioner may include that information in the public file after notifying the bank.
