The TerminatorÂ® Tooth is excellent in hard and mixed rocky soils as well as cutting tree roots and other underground objects. Rock & Frost. Use conical carbides (bullet teeth) to penetrate and fracture rock or very hard soils. Carbides are self-sharpening so long as they are able to turn in the holder.
Definite life assets (long-term depreciated assets) may also need to be tested for impairment when there is an internal or external indication that these assets might be worth less than their Carrying Amount. I was asked a number of years ago to look at the value of a clientâs inland barges.
Impaired Asset. An asset with a market value less than its value listed on the company's records, especially when the value is unlikely to recover. The cash flow an impaired asset will generate is less than the difference between its market value and its book value. A company must write down the value of impaired assets once per year. Common impaired assets include accounts receivable, long-term assets, and, especially, good will.
