Group Structure
TESORO REFINING & MARKETING COMPANY LLC sits 2 levels below its ultimate parent, Marathon Petroleum Corporation, registered in United States. 3 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to Marathon Petroleum Corporation is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by TESORO REFINING & MARKETING COMPANY LLC's own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 3 subsidiaries span United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. One of the 3 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
