ADS Shares: Is there more than one type of ADR certificate?
No. Effective with our October 4, 1999 two-for-one share split, the ADR certificate represents a Nominal Value of $0.25 per Ordinary share. Nominal Value is similar to Par Value on US stock certificates. Previous BP ADR certificates represented a Nominal Value of $0.50 per Ordinary share and previous BP ADR certificates represented the Nominal Values per Ordinary share in pence. All of these certificates are valid and have the current Nominal Value of $0.25 per Ordinary share and ratio of six Ordinary shares per ADS share.
