Each preferred unit was converted into 0.37334 Charter Holdings common unit, representing a conversion price of $267.85 per unit, based on a conversion feature as defined in the Limited Liability Company Agreement of Charter Holdings, resulting in the issuance of a total of 9.3 million common units to A/N. The convertible preferred units had a face amount of $2.5 billion and paid a 6% annual preferred dividend which was paid quarterly in cash. Net income of Charter Holdings attributable to A/N's preferred noncontrolling interest for financial reporting purposes was based on the preferred dividend which was $70 million for the year ended December 31, 2021 and $150 million for the year ended December 31, 2020.

As of December 31, 2022, A/N held 18.2 million Charter Holdings common units which are exchangeable at any time into either Charter Class A common stock on a one-for-one basis, or, at Charter’s option, cash, based on the then current market price of Charter Class A common stock. Net income of Charter Holdings attributable to A/N’s common noncontrolling interest for financial reporting purposes is based on the weighted average effective common ownership interest of approximately 11% during 2022, 7% prior to the conversion of the preferred units and 11% after conversion during 2021 and 8% during 2020, and was $792 million, $594 million and $303 million for the years ended December 31, 2022, 2021 and 2020, respectively. Charter Holdings is required to make quarterly cash tax distributions (with annual true-ups) on a pro rata basis to its partners based on the partner with the highest proportionate cash tax requirement. To the extent such tax distributions would exceed Charter’s cash tax requirements, it may waive its entitlement to tax distributions and, instead, issue a non-pro rata "advance" to A/N, which will accrue interest at a money market rate and will reduce A/N’s exchange value into cash or Charter Class A common stock. Charter Holdings distributed $110 million, $4 million and $3 million to A/N as a pro rata tax distribution on its common units during the years ended December 31, 2022, 2021 and 2020, respectively.
