As the Public Service Law prohibits the capitalization of franchises, consents or rights to engage in utility business except as provided in the Public Service Law, the commission will not approve a transfer or lease where it appears that the transferee or the lessee is paying for a franchise, consent or right to engage in utility business in excess of legitimate original cost less proper amortization. Where the amount authorized to be paid exceeds the original cost less accrued depreciation of the physical property transferred or leased, together with the unamortized portion of the actual cost incurred in securing said franchise, consent or right, the commission may refuse to approve the application unless the applicant will amortize immediately said excess through charges to surplus.
