Petroleo Brasileiro S.A. Petrob PBR
A depositary receipt. The company's shares are held on deposit in its home market and this New York listing is a claim on them, so it is the company's own equity and its financial statements describe it.
One depositary share represents 2 underlying shares. A figure quoted per underlying share is 2 times smaller than the same figure stated per depositary share.
The filing does not state a par value for the underlying share, so no home currency is claimed for it.
