Asset Impairment Charges	3. ASSET IMPAIRMENT CHARGES When circumstances, such as adverse market conditions, indicate that the carrying value of a long-lived asset may be impaired, the Company performs an analysis to review the recoverability of the asset’s carrying value. The Company makes estimates of the undiscounted cash flows (excluding interest charges) from the expected future operations of the asset. These estimates consider factors such as expected future operating income, operating trends and prospects, as well as the effects of demand, competition and other factors. If the analysis indicates that the carrying value is not recoverable from future cash flows, an impairment loss is recognized to the extent that the carrying value exceeds the estimated fair value. Any impairment losses are recorded as operating expenses, which reduce net income. In response to the Company’s current period operating losses combined with its history of continuing operating losses, the Company evaluated the recoverability of certain property and equipment. In the third quarter of 2015, the overall outlook for the sapphire market continued to be volatile as industry analysts reported significant worldwide over capacity and pricing of sapphire products reached historical lows. Based upon the Company’s assessment using its most recent projections, impairment to these assets was indicated as of September 30, 2015, as the recoverable amount of undiscounted cash flows did not exceed the carrying amount of these assets.

The Company is actively pursuing the sale of a parcel of extra land the Company owns in Batavia, Illinois. The property has a book value of $1.6 million and it is the Company’s intention to complete a sale within the next twelve-month period. Therefore, this property was reclassified as a current asset held for sale at September 30, 2016. Since the expected sale price is below the book value of the property, for the nine months ended September 30, 2016, an impairment charge of $265,000 was recorded. The Company will continue to assess its long-lived assets to ensure the carrying amount of these assets is still appropriate given any changes in the asset usage, marketplace and other factors used in determining the current fair market value.

When circumstances, such as adverse market conditions, indicate that the carrying value of a long-lived asset may be impaired, the Company performs an analysis to review the recoverability of the asset’s carrying value.
