How to list company name on resume

<p>I work at a Fortune 500 company that is co-owned. One of the owners handles most of the business in terms of HR, the engineering processes, and communication. This owner is more prestigious. The other owner is hidden basically and nobody at the firm speaks of them. How should I list this company on my resume? Should I put the first owner described or should I put the
actual name? Confused right now</p>

<p>What does it say on the front of the building? On your paycheck?</p>
