Amber Nestor has an eye for quality. She recently formed an art gallery where she allows artists to display their artwork for sale. Customers buy the artwork through the gallery, but payments are actually made payable directly to the originating artist. Artists, in turn, pay Amber a 20% commission that is appropriately reflected as revenue of the gallery.

Following is Amber's trial balance after the first year of operation. This trial balance does not reflect the adjustments that are necessary, as described by the additional information.

The Display equipment was purchased near the beginning of the year. It has a 3-year life and no salvage value. Its cost should be depreciated equally over its life.
