After achieving its ambitious three-year goals to double earnings and record a double-digit return on invested capital, Royal Caribbean Cruises on Wednesday told employees they will receive 5 percent bonuses.

Employees will receive equity awards equal to five percent of their 2017 salaries in what it called the "Thank You, Thank You Bonus." The awards, which vest over three years, will go to the company's 66,000 employees, excluding corporate officers.

In addition to the five percent equity awards, the company said it will contribute to a fund that upgrades crew living and recreational areas.

Royal Caribbean Cruises reported fourth-quarter profit and revenue that beat Wall Street estimates, helped by higher onboard spending and lower cruise operating expenses in the crucial holiday season.
