Confidence rating:

Rayner owns 16% of Cox Enterprises, a closely held conglomerate. She received the stake in December 2013 after her mother, Anne Cox Chambers, dissolved a trust that held 49.4% of Cox. Ownership is based on court documents and Cox's disclosure to Bloomberg that internal transactions resulted in equal stakes among the two owner families.

Cox Enterprises had revenue of $21.2 billion in 2019, according to the company. It has two main units: Cox Communications and Cox Automotive. 

Cox Automotive is a provider of car sales software technology. It had revenue of $7.6 billion in 2019 and is valued on the average enterprise value-to-Ebitda multiples of KAR Auction Services, CarMax and Penske Automotive.

Cox Communications is the third-largest cable operator in the U.S., according to the company's website. It had revenue of $12.2 billion in 2019 and is valued using the average enterprise value-to-Ebitda multiple of three publicly traded peer companies: Comcast, Verizon, and Rogers Communications.

Rayner's share of corporate-level debt is included as a liability.

Natalie Giurato, a Cox group spokesperson, provided revenue figures in May 2020 without further comment.
