1. Most RSU settles in cash, i.e. to avoid dilution to shareholder
2. RSU requires company to expense it according to the vesting schedule. Therefore, it is an expense on company's income statement
3. Most companies hedge their RSU grants at issue, meaning subsequent stock appreciation/depreciation has little to no impact on its earnings.
4. The income statement already fully reflected the cost of the RSU program.
