Answer:
Its incorrect treatment.
Explanation:
The reason is that the company has to accrue revenue on the grounds that the revenue would be earned on the consideration paid basis. In this scenario the company has delivered the product and services combined. The revenue from the product sale of $850 must be accrued while the $150 would be treated as deferred revenue (Unearned revenue). This deferred revenue would be divided by the number of years and allocated to the year as a accrued income.
The above treatment is inaccordance with accrual and matching concept.
