EOM paycheck - 1/2 reserve guarantee for that month (at lowest rate if on a multi payrate fleet.) + any performance bonus (D0/A0 goals. usually about $100)

15th paycheck- the difference between the dollar amount you earned the previous month and what was paid on the prior EOM paycheck. Plus all per diem.
