N.Y. Comp. Codes R. & Regs. tit. 20, § 16-2.9
(a) A branch is a bona fide office, as defined in section 16-2.8 of this Subpart, which is used by the taxpayer on a regular and systematic basis to:
(4) conduct one or more of the other functions of a banking business, such as:
(b) The following do not constitute a branch:
(c) For purposes of this section, approval shall mean final approval and final approval shall have the same meaning as set forth in paragraph (d)(4) of section 19-6.2 of this Title.
(d) Example.
In 1982, a New York office of a German bank was established. The New York office does not have authority to give final approval to loans over $50 million. Prior to 1985 and in 1986, the New York office was involved with loans of less than $50 million as well as loans in excess of $50 million and gave final approval to those loans of less than $50 million. In 1985, the New York office did not give final approval to any loans since it was only involved with loans in excess of $50 million. The New York office has accepted loan repayments, disbursed funds and conducted one or more of the other functions of a banking business since it was established. The New York office is a branch because it has been used on a regular and systematic basis to conduct all the functions required to qualify as a branch even though it did not approve any loans in 1985.
