Total pay is as the Summary Compensation Table states it; actually paid revalues the year’s share awards at its end, as the SEC’s pay-versus-performance rule asks. $100 invested is what $100 in the company’s shares at the start of the earliest year shown was worth at each year’s end. Ownership is the proxy’s own table: the directors and officers as a group, and every holder of 5% or more. Read the proxy statement
