The Secretary of the Treasury shall maintain in the unemployment trust fund established pursuant to section 904 of the Social Security Act [42 U.S.C. 1104] an account to be known as the railroad unemployment insurance administration fund. This unemployment insurance administration fund shall consist of (i) such part of all contributions collected pursuant to section 358 of this title as equals 0.65 per centum of the total compensation on which such contributions are based; (ii) all amounts advanced to the fund by the Secretary of the Treasury pursuant to this section; (iii) all amounts appropriated by subsection (b) of this section; and (iv) such additional amounts as Congress may appropriate for expenses necessary or incidental to administering this chapter. Such additional amounts are authorized to be appropriated.

In addition to the other moneys herein provided for expenses necessary or incidental to administering this chapter, there is appropriated to the fund such amount as the Secretary of the Treasury and the Board shall jointly estimate to have been collected or to be collectible with respect to the calendar years 1936, 1937, 1938, and 1939, from employers subject to this chapter, under title IX of the Social Security Act, less such amount as the Secretary of the Treasury and the Board shall jointly estimate will be appropriated or has been appropriated to States or Territories pursuant to the Act of Congress approved August 24, 1937 (Public, Numbered 353, Seventy-fifth Congress), as proceeds of taxes paid by employers pursuant to title IX of the Social Security Act.

Until the amount appropriated by this subsection is credited to the fund, the Secretary of the Treasury is directed to advance to the credit of the fund such sums, but not more than $2,000,000, as the Board requests for the purpose of financing the costs of administering this chapter. Such advance shall be repaid from the fund at such time after the amount appropriated by this subsection is credited to the fund as the Board by agreement with the Secretary of the Treasury may determine, but not later than January 1, 1940.

Notwithstanding any other provision of law, all moneys at any time credited to the fund are permanently appropriated to the Board to be continuously available to the Board without further appropriation for any expenses necessary or incidental to administering this chapter, including personal services in the District of Columbia and elsewhere; travel expenses, including expenses of attendance at meetings when authorized by the Board; actual transportation expenses and not to exceed $10 per diem to cover subsistence and other expenses while in attendance at and en route to and from the place to which he is invited, to any person other than an employee of the Federal Government who may, from time to time, be invited to the city of Washington or elsewhere for conference or advisory purposes in furthering the work of the Board; when found by the Board to be in the interest of the Government, not exceeding 3 per centum, in any fiscal year, of the amounts credited during such year to the fund, for engaging persons or organizations, by contract or otherwise, for any special technical or professional services, determined necessary by the Board, including but not restricted to accounting, actuarial, statistical, and reporting services, without regard to section 6101 of title 41 and the provisions of other laws applicable to the employment and compensation of officers and employees of the United States; services; advertising, postage, telephone, telegraph, teletype, and other communication services and tolls; supplies; reproducing, photographing, and all other equipment, office appliances, and laborsaving devices, including devices for internal communication and conveyance; purchase and exchange, operation, maintenance and repair of motor-propelled passenger-carrying vehicles to be used only for official purposes in the District of Columbia and in the field; printing and binding; purchase and exchange of law books, books of reference, and directories; periodicals, newspapers and press clippings, in such amounts as the Board deems necessary, without regard to the provisions of section 192 of the Revised Statutes; manuscripts and special reports; membership fees or dues in organizations which issue publications to members only, or to members at a lower price than to others, payment for which may be made in advance; rentals, including garages, in the District of Columbia or elsewhere; alterations and repairs; if found by the Board to be necessary to expedite the certification to the Board by the Director of the Office of Personnel Management of persons eligible to be employed by the Board, and to the extent that the Board finds such expedition necessary, meeting the expenses of the Director of the Office of Personnel Management in holding examinations for testing the fitness of applicants for admission to the classified service for employment by the Board pursuant to the second paragraph of section 362(l) of this title, but not to exceed the additional expenses found by the Board to have been incurred by reason of the holding of such examinations; and miscellaneous items, including those for public instruction and information deemed necessary by the Board: Provided, That section 6101 of title 41 shall not be construed to apply to any purchase or procurement of supplies or services by the Board from moneys in the fund when the aggregate amount involved does not exceed $300. Determinations of the Board whether the fund or an appropriation for the administration of the Railroad Retirement Act of 1974 [45 U.S.C. 231 et seq.] is properly chargeable with the authorized expenses, or parts thereof, incurred in the administration of such Act, or of this chapter, shall be binding and conclusive for all purposes and upon all persons, including the Comptroller General and any other administrative or accounting officer, employee, or agent of the United States and shall not be subject to review in any manner.
