(i) A bank holding company, a national bank, a state chartered bank, an office of thrift supervision chartered bank or thrift institution, or a savings and loan holding company other than a diversified savings and loan holding company as defined in 12 USC 1467a(a)(F).
(ii) Any person, other than a person subject to the tax imposed under chapter 2A, who is directly or indirectly owned by an entity described in subparagraph (i) and is a member of the unitary business group.
(iii) A unitary business group of entities described in subparagraph (i) or (ii), or both.
Thus, even though a mortgage company is not expressly defined as a financial institution, it will be considered a financial institution if it is owned directly or indirectly by a financial institution and is a member of the unitary business group that the parent financial institution is also a member. If a mortgage company meets these criteria, it is a financial institution under the MBT.
