Segment Reporting Disclosure

13 - SEGMENT INFORMATION

The Company is a bank holding company, the principal subsidiary of which is the Bank. The Bank provides a variety of banking, investment, and financial services through its retail branches, commercial banking centers, investment management offices, and mortgage lending centers throughout Eastern Massachusetts, as well as in Worcester County; Southern New Hampshire; and Rhode Island. The Bank is a community-oriented commercial bank, and has only one reportable segment, which is community banking. The community banking segment derives revenues primarily from providing loans to individuals and small-to-medium sized businesses in its market area. The accounting policies of the community banking segment are the same as those described in Note 1, “Summary of Significant Accounting Policies” within the Notes to Consolidated Financial Statements included in Item 8 of the 2024 Form 10-K.

The Company’s reportable segment is determined by the Chief Executive Officer and Chief Financial Officer, who are the Company’s designated chief operating decision makers (“CODMs”), based upon information about the Company’s products and services offered to customers as part of its community banking operations. The CODMs assess performance for the community banking segment and decide how to allocate resources based on the Company’s consolidated net income and diluted earnings per share, as reported in the Consolidated Statements of Income. The significant expense categories reviewed by the CODMs are also consistent with those presented on the Consolidated Statements of Income, with an emphasis on interest expense on deposits and borrowings, as well as provision for credit losses, salaries and benefits, and occupancy and equipment costs. Other segment expenses are comprised of the remaining expense categories presented on the Consolidated Statements of Income, including other non-interest expenses. Other non-interest expenses are inclusive of costs related to professional services, advertising, technology and communications costs, and various other general and administrative costs. Net income and diluted earnings per share are used by the CODMs to monitor management’s budgeted results versus actual, as well as to benchmark the Company’s relative performance against other banking institutions in its peer group. The results of these monitoring and benchmarking analyses are used in assessing performance of the community banking segment and to inform decisions surrounding general corporate strategy, capital allocations, and compensation. Asset details provided to the CODMs are consistent with those reported on the Consolidated Balance Sheets, with an emphasis on interest-earning assets, including loans and investment securities, which provide the majority of revenues generated by the community banking segment.
