• DEPRECIATION CONVENTION
  
  utilized to determine how much depreciation to charge the first year when an item is bought part way through the year. Three different conventions are used: 1. Half year convention - All property placed in service is considered to be placed in service half way through the year. During the first year, half of the "normal" depreciation is taken. At the end of the depreciation period, the other half of the "normal" depreciation is taken; 2. Mid-quarter convention - If the amount of depreciation claimed on new items during the last 3 months of a year exceeds 40% of the total depreciation claimed during the year, then the mid-quarter convention is used. The amount of depreciation of each item is figured for one year then multiplied by 87.5% if was placed in service during Jan. - March, 62.5% if it was placed in service during April - June, 37.5% for items placed in service during July-Sept, and 12.5% for items placed in service during Oct. - Dec.; or, 3. Mid-month convention - All property is considered to be placed in service during the midpoint of the month. This requires some calculations.
