Notwithstanding any other provision of the constitution, the city is hereby authorized to contract indebtedness for such purposes and to deliver its obligations evidencing such indebtedness to the corporations owning the railroads, facilities, properties or rights acquired, to the holders of securities of such owning corporations, to the holders of securities of corporations holding the securities of such owning corporations, or to the holders of securities to which such acquired railroads, facilities, properties or rights are now subject.
B. Indebtedness contracted by the city for transit purposes, and not otherwise excluded, proportionately to the extent to which the current net revenue received by the city from all railroads and facilities and properties used in connection therewith and rights therein owned by the city and securities of corporations owning such railroads, facilities, properties or rights, owned by the city, shall meet the interest and the annual requirements for the amortization and payment of such non-excluded indebtedness.
In determining whether indebtedness for transit purposes may be excluded under this paragraph of this section, there shall first be deducted from the current net revenue received by the city from such railroads and facilities and properties used in connection therewith and rights therein and securities owned by the city:
(b) an amount equal to the interest on indebtedness contracted pursuant to this section and of the annual requirements for amortization on any sinking fund bonds and for redemption of any serial bonds evidencing such indebtedness;
(c) an amount equal to the sum of all taxes and bridge tolls accruing to the city in the fiscal year of the city preceding the acquisition of the railroads or facilities or properties or rights therein or securities acquired by the city hereunder, from such railroads, facilities and properties; and
(d) the amount of net operating revenue derived by the city from the independent subway system during such fiscal year. The legislature shall prescribe the method by which and the terms and conditions under which the amount of any indebtedness to be excluded hereunder shall be determined, and no indebtedness shall be excluded except in accordance with the determination so prescribed. The legislature may confer appropriate jurisdiction on the appellate division of the supreme court in the first judicial department for the purpose of determining the amount of any debt to be so excluded.
