Revenue has been recorded for months expired in the year i.e.
Unearned Revenue x Months expired / 12
=576000*12/12+432000*11/12+648000*5/12+864000*1/12
Monthly Sales revenue per subscription is $72/12 = $6 per
subscription
Monthly cost = $3
Cost of sales = $3/$6 x 100 = 50%
Therefore related expense for current year = $1314000 x 50% =
$657000
