Income from continuing operations before interest expense and related charges and provisions in lieu of income tax, plus depreciation and amortization and special items. Also adjusted for the effect of the SARs exercise, where applicable. EBITDA is a measure used by Oncor to assess

Adjusted EBITDA (non-GAAP) performance.

Total debt less transition bonds divided by EBITDA. Transition, or securitization, bonds are serviced by a regulatory transition charge on wires Debt/Adjusted EBITDA rates and are therefore excluded from debt in credit reviews. Debt / EBITDA is (non-GAAP) a measure used by Oncor to assess credit quality.

Adjusted EBITDA/Cash Interest EBITDA divided by cash interest expense is a measure used by Oncor to (non-GAAP) assess credit quality.
