To calculate the average annual wage of a covered Part E employee as defined in § 30.801(a), OWCP will:

(a) Aggregate the wages for the 36 months that preceded the trigger month, excluding any month during which the employee was unemployed;

(b) Add any additional wages earned by the employee during those same months as evidenced by records described in § 30.807;

(c) Divide the sum of paragraphs (a) and (b) of this section by 36, less the number of months during which the employee was unemployed; and

(d) Multiply this figure by 12 to calculate the covered Part E employee's average annual wage.
