Illinois Statutes Chapter 220. Utilities § 5/13-508. Separate subsidiary for competitive service

(a) no less costly means is available and effective in fully and properly identifying and allocating costs between such carrier's competitive and noncompetitive telecommunications services; and

(b) the incremental cost of establishing and maintaining such subsidiary would not require increases in rates or charges to levels which would effectively preclude the offer or provision of the affected competitive telecommunications service.
