Sheldon uses straight-line depreciation on all depreciable assets and assumes the assets will have no value at the end of their estimated useful lives. A full month's depreciation is taken for the month of purchase, regardless of which day of the month the purchase is made. For example, depreciation expense for the three months ended March 31, 2018, on the phone system is $200 (i.e., $2,400/3 years x 3/12 of a year). Land is not considered depreciable. You may use a single account (Depreciation Expense) to record all of the depreciation expense for the depreciable assets. Also, you may use a single account (Accumulated Depreciation) to record the effect of depreciation on total assets.

Sheldon must record accrued interest for one month on the $45,000 bank loan.

Sheldon estimates utilities used during March amounted to $1,800, although the bill has not yet been received.

Remember insurance that has expired.
