1/ IRA-12, Column (s), Allocated to Texas Operations

2/ IRA-12, Col (s), Lines 8, 9, and 109. This adjustment represents capital costs of $1,869,132 associated with a 42-mile 10” mainline project in Dimmitt and LaSalle Counties, and $647,630 incurred on the purchase of the City of White Deer. These capital

costs are being excluded from the interim rate adjustment calculation due to allocation methods established in Docket No. 10235 that would unfairly burden WTG jurisdictional customers. WTG will defer including these capital costs until its next

rate case filing pursuant to Utility Code 104.301.
