Prothena  (NAS:PRTA) Shareholder Yield % Explanation

Shareholder Yield % is how much money shareholders receive from a company that is in the form of cash dividends, net stock repurchases, and debt reduction. The term was coined by William W. Priest of Epoch Investment Partners in a paper in 2005 entitled The Case for Shareholder Yield as a Dominant Driver of Future Equity Returns. William Priest indicated that "shareholder yield is a term that we came up with to reflect the various ways dividends can be paid to owners of a business in a publicly-traded company."

Shareholder Yield % is calculated by three components: Dividend Yield %, Buyback Yield %, and Net Debt Paydown Yield %.

Dividend Yield % shows how much a company pays out in dividends each year relative to its stock price, which is most obvious form of shareholder return.

Buyback Yield % is the net repurchase of shares outstanding over the market capital of the company. Shares repurchases also increase shareholder value by returning the money back to shareholders.

Net Debt Paydown Yield % is the change in average of four quarters of company's total debt over a company's market cap. Assuming the total value of a company remains that same, shareholder value is increased as debt is reduced.
