Each full-time employee of Sunshine Greenhouse is entitled to ten paid sick days each year. The sick pay does not vest and cannot be carried over to subsequent years. Sunshine Greenhouse should:

Recognize sick pay as an expense when actually paid.

Recognize an estimated current liability for unused sick pay at the end of each period.

Recognize an estimated non-current liability for unused sick pay at the end of each period.

Accrue sick pay based on historic rates of absenteeism.
