performance right financial

"Each performance right represents a contingent right to receive one share of common stock"

restricted stock financial

"Restricted stock: all shares are subject to time vesting"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

total shareholder return financial

"based on the achievement of performance criteria related to the Company's total shareholder return relative to industry indices"

Total shareholder return is the overall gain an investor gets from owning a stock, combining changes in the share price plus any cash payouts like dividends, and assuming those payouts are reinvested in more shares. Investors use it like a single score that shows the true return on their investment—similar to checking both the growth of a savings account and the interest earned—to compare how well different companies or investments perform over time.

three-year performance period financial

"financial results over a three-year performance period"

contingent right financial
