Gazra Inc. established a defined contribution pension plan at the beginning of 20X5. The company will contribute a specified percentage of each employee’s annual salary. These payments vest immediately, but the percentage contributed depends on the number of years that the employees have been with the organization. In addition, employees can elect to contribute additional funds as a direct deduction from their pay. For the employees that make this election, the contribution is matched by Gazra.

The following is the percentage of total salaries with employees that elected into the voluntary contribution plan:
