Study Area Total Unseparated Loop Cost

(a) For the purpose of calculating the expense adjustment, the study area total unseparated loop cost equals the sum of the following, however, subject to the limitations set forth in § 54.303:

(1) Return component for net unseparated Exchange Line C&WF subcategory 1.3 investment and Exchange Line CO Circuit Equipment Category 4.13 investment. This amount is calculated by deducting the accumulated depreciation and noncurrent deferred Federal income taxes attributable to C&WF Subcategory 1.3 investment and Exchange Line Category 4.13 circuit investment reported pursuant to § 54.1305(b) from the gross investment in Exchange Line C&WF Subcategory 1.3 and CO Category 4.13 reported pursuant to § 54.1305(a) to obtain the net unseparated C&WF Subcategory 1.3 investment, and CO Category 4.13 investment.
