Sec. 105. Section 702 of title 39, United States Code, is amended to read as follows: “§702. Classes of post offices “(a) Effective at the beginning of each fiscal year the Postmaster General shall divide post offices into four classes on the basis of the revenue units of each office for the second preceding fiscal year. He shall place in the first class those post offices having 950 or more revenue units. He shall place in the second class those post offices having 190 or more revenue units, but fewer than 950 revenue units. He shall place in the third class those post offices having 36 or more revenue units, but fewer than 190 revenue units. He shall place in the fourth class those post offices having fewer than 36 revenue units. “(b) The Postmaster General shall exclude from the revenue credited to a post office for the purposes of this section money received at that office for— “(1) setting meters for patrons beyond the area served by the office unless authorized by the Department; “(2) stamps, stamped envelopes, and postal cards sold in large or unusual quantities to be used in mailing matter at other offices; and “(3) stamps, stamped envelopes, and postal cards sold for mailing matter diverted from other offices and mailing of matter so diverted without stamps affixed. “(c) Whenever unusual conditions prevail at a post office of the fourth class, the Postmaster General may advance such office to the appropriate class based on his estimate of the number of revenue units which the office will have during the succeeding twelve months. Any office so advanced need not be relegated to a lower class before the end of the second fiscal year after the advancement. At that time, the office shall be assigned to the appropriate class in accordance with subsections (a) and (b) of this section.”
