ANNOTATION
No commerce clause violation. Where the utility's intangible property, in-state circuits leased by the utility to transmit calls in and out of state, provides a sufficient nexus between the utility and the state to support a tax, and where the tax was apportioned in the tax administrator's judgment to represent the value of the utility's property and plant within the state, the resulting valuation for assessment did not violate the commerce clause. U.S. Transmission Sys. v. Bd. of Assmt. Appeals, 715 P.2d 1249 (Colo. 1986).
Allocation formula for apportioning the unitary value of a telephone company's property to Colorado. In the absence of a showing of significant prejudice by petitioner, the board's employment of a single factor allocation formula based on gross revenues was in compliance with the tax administrator's statutory charge to apportion fairly the value of the property and plant to represent the value attributable to the state. U.S. Transmission Sys. v. Bd. of Assmt. Appeals, 715 P.2d 1249 (Colo. 1986).
