I’m not confident that “total shares outstanding” has anything to do with preferred shares. I would ask that the OP provide more context so we can be more sure. What were the specific questions or examples that led to your inquiry?
Thank you for providing an example. You’re putting too much thought into it. “Weighted average number of shares outstanding” AND “Weighted average number of ordinary shares outstanding” refer to the same thing. There is a difference between basic and diluted, which is explained in the material. However, regardless of whether basic or diluted number of shares outstanding is used, the final number is the total common shares outstanding.
As I mentioned in my previous response, you would not use preferred shares in either calculation.
Weighted average number of shares outstanding= weighted average number of ordinary shares outstanding= weighted average number of common shares outstanding.
