Calculating Invalidity and Invalidity Post 94 Payments

The calculation rule for earning INVALIDITY is Amount, and the amount is Payee Level. It is another earning for which you enter the value by positive input and that does not add to AUS gross. It does, however, add to the accumulator TER AC ETP. It also adds to its own accumulator TER AC INVALIDITY.

The calculation rule for earning INV POST 94 is Amount, and the amount is formula TER FM INV POST94.

Note:

Despite its name, the calculation of post 94 invalidity earning does not involve any durations based on the year 1994.

The formula multiplies the amount of accumulator TER AC INVALIDITY (added to by your positive input) by duration TER DR TERM RETIRE, which calculates the days from the employee's termination date to his or her normal retirement date. It then divides by duration TER DR HIRE RETIRE, which calculates the days from the employee's hire or rehire date to normal retirement date.

Accumulator amount × days from term to norm retirement / days from hire (or rehire) to norm retirement = TER FM INV POST94 = earning INV POST 94

The start date for duration TER DR HIRE RETIRE is formula TER FM DUR START, which returns the rehire date if the hire date is earlier than the rehire date.

Because the positive input for earning INVALIDITY adds to TER AC ETP, and earning INV POST 94 subtracts from it, the balance of INVALIDITY is processed as any other ETP payment.
