Deferred share unit financial

"A deferred share unit ("DSU") entitles the holder"

Omnibus Equity Incentive Plan financial

"administrator of the Issuer’s Omnibus Equity Incentive Plan"

A single, company-wide plan that lets a business grant different kinds of stock-based pay — such as stock options, shares that vest over time, or other equity awards — to employees, directors and consultants. It matters to investors because it determines how much of the company can be paid out in shares, how quickly those shares enter the market, and how well employees are motivated to grow the business; think of it as a toolbox or menu for paying with ownership stakes that can dilute existing holders and affect company performance.
