Note 2.    Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation for Gamma Knife units and other equipment is determined using the straight-line method over the estimated useful lives of the assets, which for medical and office equipment is generally 3 – 10 years, and after accounting for salvage value on the equipment where indicated. As of   April 1, 2021, the Company reduced its estimate for salvage value for nine of its Gamma Knife units. The net effect of this change in estimate for the three and six-month periods ended June 30, 2022, was a decrease in net income of approximately $114,000 or $0.02 per diluted share and $228,000 or $0.04 per diluted share, respectively. The net effect of this change in estimate for the three and six-month periods ended June 30, 2021, was a decrease in net income of approximately $114,000 or $0.02 per diluted share. Salvage value is based on the estimated fair value of the equipment at the end of its useful life. This change in estimate will also impact future periods. The Company determines salvage value based on the estimated fair value of the equipment at the end of its useful life.

Depreciation for PBRT equipment is determined using the modified units of production method, which is a function of both time and usage of the equipment. This depreciation method allocates costs considering the projected volume of usage through the useful life of the PBRT unit, which has been estimated at 20 years. The estimated useful life of the PBRT unit is consistent with the estimated economic life of 20 years.
