Financial Definitions
Measure Definition
Adjusted Operating Revenues (non-GAAP) Oncor operating revenues, less operating revenues of Oncor Electric Delivery Transition Bond Company LLC (BondCo)
Adjusted Net Income (non-GAAP) Oncor net income, less effects of purchase accounting and net income of BondCo
Adjusted Operating Cash Flow (non-GAAP) Oncor cash provided by operating activities, less BondCo cash provided by operating activities
Debt (non-GAAP) Oncor total debt, less transition bonds of BondCo
Total Debt (GAAP) Oncor long-term debt (including current portion) plus bank loans
Adjusted EBITDA (non-GAAP) Income from continuing operations before interest expense and related charges and provisions in lieu of income tax, plus depreciation and amortization and special items, less BondCo results. EBITDA is a measure used by Oncor to assess performance.
Debt/Adjusted EBITDA (non-GAAP) Total debt less transition bonds divided by Adjusted EBITDA. Transition, or securitization, bonds are serviced by a regulatory transition charge on wires rates and are therefore excluded from debt in credit reviews. Debt / EBITDA is a measure used by Oncor to assess credit quality.
Adjusted EBITDA/Cash Interest (non-GAAP) Adjusted EBITDA divided by cash interest expense is a measure used by Oncor to assess credit quality.
