"Base salary" means the salary provided pursuant to a salary guide or table and any amount provided pursuant to a salary increment, including any amount provided for longevity or length of service. It also shall include any other item agreed to by the parties, or any other item that was included in the base salary as understood by the parties in the prior contract. Base salary shall not include non-salary economic issues, pension and health and medical insurance costs.
"Non-salary economic issues" means any economic issue that is not included in the definition of base salary.
The parties may agree, or the arbitrator may decide, to distribute the aggregate monetary value of the award over the term of the collective negotiation agreement in unequal annual percentage increases, which shall not be greater than the compounded value of a 2.0 percent increase per year over the corresponding length of the collective negotiation agreement. An award of an arbitrator shall not include base salary items and non-salary economic issues which were not included in the prior collective negotiations agreement.
