remaining assets in account

Remaining assets? You mean the asset points that are not yet used for licensing an item?

Those assets will be forfeit at the end of your subscription. I recommend to licence assets that may be of use for you, before they run out. Please note also that depending on the subscription type (annual, paid monthly) and the date of the cancel (before the last month of your subscription) you need to pay an early termination fee of half of the remaining due.

The items that you have licensed stay at your disposal forever and can be used according to the licensing terms.
