Brockton-based HarborOne Credit Union is considering converting to a state-chartered, mutual cooperative bank.

In a notice posted to its website Thursday, the credit union says the decision to convert rests, in some sense, with its members. "If after reviewing comments received by members, the board of directors votes to proceed with the conversion, you will receive a notice…that provides greater detail…," the notice read in part.

HarborOne’s notice says it is considering the conversion for greater flexibility to expand its customer base and access to additional capital.

In the event of a conversion, HarborOne’s members would become depositors in the bank. Fees, rates and deposit insurance levels would not change, it says in the statement. Directors, who are not currently compensated for their service, would be compensated as members of a bank board of directors.

The statement says the state and federal income taxes the credit union would be required to pay as a bank would be "more than offset by the enhanced earnings capacity through commercial and small business lending" and adding more customers.

President and CEO James Blake is fielding comments himself. The HarborOne board of directors intends to consider the conversion during a meeting scheduled for March 21.

Blake could not be reached for comment this afternoon.

"It’s not uncommon nationally," Dan Forte, president of the Massachusetts Bankers Association, told Banker & Tradesman Thursday. "And as one of the larger credit unions in Massachusetts, it seems like a natural progression. They’ve been a very progressive, bank-like entity. They have the complete panoply of products and services, even beyond what some small banks may have."

In a statement, the Massachusetts Credit Union League urged caution on the part of HarborOne’s members.

"The League strongly believes the member-owned, not-for-profit, credit union charter is the charter of choice for providing the public with consumer-friendly financial products and services, and allows credit unions to offer a far better economic return," said league President Daniel F. Egan Jr.
