      3. The value of special rewards for individual invention or discovery
      4. Dismissal or severance payments except for time worked or accrued vacation
   3. OVERTIME
      1. This is the premium pay amount only, of hours worked for which an additional premium pay is made. Premium pay is that amount which is in excess of regular pay
      2. In the case of guaranteed wage agreements, overtime means only those hours worked in excess of the number specified in such agreements
   4. EXCLUSION OF OVERTIME PAYROLL
      1. Extra (premium) pay for overtime is excluded from payroll on which tax premium is calculated, provided payroll records are kept to show overtime pay separately, by employee, and summarized by classification code
      2. Extra (premium) pay is the difference between an employee’s regular pay rate and their overtime pay rate multiplied by the number of overtime hours worked
      3. EXAMPLE:
         Bob earns $10/hour for a regular 40-hour workweek and $15/hour for anything over 40 hours.
         Bob worked 46 hours last week. His payroll is calculated by:
         $15 (overtime pay) - $10 (regular pay) = $5 (extra/premium pay)
         46 hours @ $10/hour = $460 (regular pay)
         6 hours @ $ 5/hour = $ 30 (extra/premium pay)
         ​Only the $30 may be excluded from the payroll as overtime (extra/premium) pay.
   5. EXECUTIVE OFFICER PAYROLL

      For executive officers and classifications with notes indicating payroll limitations, the payroll on which premium is based shall exclude that part of the employee’s average weekly pay in excess of applicable weekly limitations provided employer maintains accurate records by employee and separate records are maintained in summary by classification code (Include $4,800 weekly or $249,600 annually maximum annual reportable per individual)
