ASSETS HELD FOR SALE AND LONG-LIVED ASSETS	6. ASSETS HELD FOR SALE AND LONG-LIVED ASSETS 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 using 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. The estimated fair value of assets is determined using appraisal techniques which assume the highest and best use of the asset by market participants, considering the use of the asset that is physically possible, legally permissible, and financially feasible at the measurement date. Any impairment losses are recorded as operating expenses, which reduce net income. In connection with the Company’s decision in 2016 to limit its focus to the optical and industrial sapphire markets and exit the LED market, the Company developed a plan to close its Malaysia facility, scale down and consolidate remaining operations in the U.S. and sell additional assets that would not be needed. The Company evaluated its U.S. and Malaysia asset portfolios to identify assets needed for its current business strategy and excess assets that were no longer needed. The Company determined it had excess machinery, equipment and facilities. Excess U.S. and Malaysia assets were evaluated based on assuming an orderly liquidation plan, which considers economic obsolescence and sales of comparable equipment, as it is the Company’s intention to sell these assets. Additionally, the Company evaluated its U.S. assets continuing to be used in operations using a cost and market approach to determine the current fair value. In the year ended December 31, 2019, we completed the sale of the remaining excess equipment located in Malaysia for total consideration of $490,000. Such equipment had a total net book value of $188,000, thereby resulting in a gain on disposal of $302,000. The Company entered into an agreement for the sale of its Malaysian facility in December 2019, which was completed in June 2020. In June 2020, the Company completed the sale of its Malaysian facility for a net sale price of approximately $4,800,000 (based on the exchange rate on June 30, 2020 of $1=MYR4.27) after the payment of consent fees, real estate taxes, brokerage and legal fees, transfer and other expenses. The Company recorded a gain on the disposal of the Malaysian facility of approximately $1,800,000. In December, 2020, the Company completed the sale of all of the outstanding shares of capital stock (the “Capital Shares”) of its wholly owned subsidiary Rubicon Sapphire Technology (Malaysia) SDN. BHD. The company recorded a gain on the sale of $261,000. On February 7, 2022, we entered into a real estate sale contract to sell our parcel of land in Batavia, Illinois for $722,000 and expect our net proceeds, if the sale is consummated, after the payment of fees, real estate taxes, brokerage and legal fees, transfer and withholding taxes and other expenses to be approximately $600,000. The closing of the sale of the Property is subject to certain conditions precedent. There is currently no anticipated closing date.
