Net leverage ratio
Following the tower disposal and the subsequent move to Adjusted EBITDAaL, and effective Q2 2022, we have changed the way we are calculating net total leverage. Net total leverage is now calculated using net debt excluding leases and is divided by the last two quarters' annualized Adjusted EBITDAaL. On this metric, our net total leverage at March 31, 2023 reached 3.6x versus 3.4x at December 31, 2022 given the decline in our Adjusted EBITDAaL as discussed above. Under the previous net total leverage definition, using net debt including leases divided by the last two quarters' annualized Adjusted EBITDA, our net total leverage was 4.0x at March 31, 2023 (December 31, 2022: 3.9x).
Our net covenant leverage, as calculated under the 2020 Amended Senior Credit Facility, differs from our net total leverage as it excludes (i) any vendor financing-related short-term liabilities, (ii) any liabilities related to the mobile spectrum licenses, yet includes (iii) the Credit Facility Excluded Amount (which is the greater of €400.0 million and 0.25x Consolidated Adjusted Annualized EBITDA) and (iv) divides Net Total Debt by the last two quarter's annualized EBITDA. Our net covenant leverage reached 2.4x at March 31, 2023, up versus 2.2x at December 31, 2022 as a result of a softer Adjusted EBITDA performance in the quarter as discussed above and a lower cash balance. Our current net covenant leverage ratio is significantly below the springing maintenance covenant of 6.0x and the incurrence test of 4.5x net senior leverage. The aforementioned maintenance covenant only applies, however, in case we would draw 40% or more under our revolving credit facilities. At March 31, 2023, our revolving credit facilities were fully undrawn as mentioned above.
For a reconciliation of both our net total leverage and net covenant ratio as per March 31, 2023, we refer to the Q1 2023 Investor & Analyst Toolkit.
(1) Net total leverage is defined as the sum of loans and borrowings under current and non-current liabilities (excluding lease-related liabilities) minus cash and cash equivalents ("Net Total Debt"), as recorded in the Company's statement of financial position, divided by the last two quarters' Consolidated Annualized Adjusted EBITDAaL. In its statement of financial position, Telenet's USD-denominated debt has been converted into EUR using the March 31, 2023 EUR/USD exchange rate. As Telenet has entered into several derivative transactions to hedge both the underlying floating interest rate and exchange risks, the EUR-equivalent hedged amounts were €2,041.5 million (USD 2,295.0 million Term Loan AR) and €882.8 million (USD 1.0 billion Senior Secured Notes due 2028), respectively. For the calculation of its net leverage ratio, Telenet uses the EUR-equivalent hedged amounts given the underlying economic risk exposure. Net total leverage is a non-GAAP measure as contemplated by the U.S. Securities and Exchange Commission's Regulation G.
(2) Net covenant leverage is calculated as per the 2020 Amended Senior Credit Facility definition, using Net Total Debt (using the €-equivalent hedged amounts for its USD-denominated debt as highlighted above), excluding (i) subordinated shareholder loans, (ii) capitalized elements of indebtedness under the Clientele and Annuity Fees, (iii) any finance leases entered into on or prior to August 1, 2007, (iv) any indebtedness incurred under the network lease entered into with the pure intermunicipalities, (v) any vendor financing-related liabilities, and including (vi) the Credit Facility Excluded Amount (which is the greater of (a) €400.0 million and (b) 0.25x Consolidated Annualized Adjusted EBITDA), divided by last two quarters’ Consolidated Annualized Adjusted EBITDA.
