Answer:
$450,000
Explanation:
Deferred subscription revenue (or unearned subscription revenue) is a liability account since your customers paid you in advance for goods or services that you must provide in the future.
The net unearned revue for 2018 and 2019 is = $390,000 and $460,000 respectively.
Of the 2018 amount, only $115,000 (= $390,000 - $115,000 - $160,000) remain as a liability during 2019 since they expire on 2020.
Of the 2019 amount, $335,000 (= $460,000 - $125,000) remain as a liability during 2019 since they expire on 2020 and 2021.
By December 31, 2019, unearned revenue = $115,000 + $335,000 = $450,000
