NICs are calculated based on the shortest earnings period for
the not contracted-out employment(s).
Example 1
If a person with an APP has two jobs in which one is
contracted-out with a weekly earnings period and the other is not
contracted-out with a monthly earnings period the earnings period
for NICs purposes is monthly.
Example 2
If a person has three jobs in which one is contracted-out
employment with a monthly earnings period, one is not
contracted-out with a weekly earnings period and the third is not
contracted- out with a four weekly earnings period, the earnings
period for NICs purposes is weekly.
