Impairment Of Long Lived Assets Disclosure [Abstract] |
IMPAIRMENT OF LONG-LIVED ASSETS | (C) IMPAIRMENT OF LONG-LIVED ASSETS We assess our long-lived assets, including mining and related assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, or group of assets, may not be recoverable. We evaluate long-lived assets or groups of assets, for impairment at the lowest level for which cash flows are largely independent of the cash flows of other assets. When impairment indicators are identified, we first assess recoverability of assets, or group of assets, by comparing the carrying amount of an asset, or group of assets, to the future undiscounted net cash flows that we expect the asset, or group of assets, to generate. These impairment evaluations are significantly affected by estimates of future revenue, costs and expenses and other factors. If the carrying value of the assets or group of assets exceeds the undiscounted cash flows, then an impairment is indicated. If such assets or group of assets are considered to be impaired, the impairment is recognized as the amount by which the carrying amount of the asset, or group of assets, exceeds the fair value of the asset, or group of assets. During the second half of calendar year 2019, our Oil and Gas Proppants financial results have been negatively affected by a combination of low demand for our products and the increased use of in-basin sand instead of northern white frac sand. Faced with these dynamics, in connection with the preparation of our financial statements for the three and nine months ended December 31, 2019, we concluded that the reduction in sales volumes and operating losses were other than temporary and that long-lived asset impairment indicators were present in our Oil and Gas Proppants segment. Prior to performing recoverability tests to determine whether an impairment was present, we grouped the long-lived assets of the segment into the lowest level at which cash flows are generated, which is considered the operating facility or distribution level. We included the value of our lease right-of-use assets that support the operating facilities within the value of the operating facility prior to performing our recoverability tests. We then performed recoverability tests on each group of assets using probability-weighted estimates of forecasted undiscounted cash flows over the remaining estimated life of each asset group based on a variety of scenarios. Based on these forecasts, we concluded that the carrying values exceeded the undiscounted cash flows for our New Auburn, Wisconsin and Utica, Illinois operating facilities and several distribution facilities related to these operating facilities, indicating impairment. For those impaired asset groups, we calculated the estimated fair value of the operating facilities in New Auburn, Wisconsin, Utica, Illinois and related distribution terminals, using a discounted cash flow model (Level 3), which utilized a weighted-average cost of capital determined from relevant market comparisons and adjusted for specific risks. We compared the results of the discounted cash flow model to other recent market information about the value of similar assets, noting the amounts to be consistent. The analysis resulted in an impairment loss of approximately $216.8 million. The following is a summary of impact of the impairment on the net book value of the long-lived assets:
|  | Net Book Value Before Impairment |  |  | Impairment |  |  | Net Book Value After Impairment |
|  | (dollars in thousands) |
Operating Facilities |  | $ | 170,324 |  |  | $ | (164,449 | ) |  | $ | 5,875 |
Transload Locations |  |  | 23,254 |  |  |  | (21,805 | ) |  |  | 1,449 |
Real Estate |  |  | 1,427 |  |  |  | (1,377 | ) |  |  | 50 |
Lease Right-of-Use Assets |  |  | 32,834 |  |  |  | (29,146 | ) |  |  | 3,688 |
|  | $ | 227,839 |  |  | $ | (216,777 | ) |  | $ | 11,062 |
We continue to be subject to volatility in the energy markets. We will continue to assess the remaining long-lived assets for impairment, as necessary, when facts and circumstance indicate an impairment might be present. Additionally, we are actively pursuing alternatives for this business. If this results in an alternative use or disposal of the business, additional losses may be incurred. In addition to the impairment of the operating facilities and transload facilities, we also assessed other current and long-term assets for impairment. As part of this analysis, we wrote down certain Inventories, Prepaid and Other Current Assets, Accounts and Note Receivable and Other Assets. The following is a summary of Impairment Losses recognized during the three months ended December 31, 2019, by line item:
|  | (dollars in thousands) |
Property, Equipment, and Real Estate |  | $ | 187,631 |
Lease Right-of-Use Assets |  |  | 29,146 |
Inventories |  |  | 6,256 |
Accounts and Notes Receivable |  |  | 617 |
Prepaid and Other Assets |  |  | 617 |
|  | $ | 224,267 |
The above Impairment Loss has been presented as a single line item on our Unaudited Consolidated Statement of Earnings (Loss) for the three and nine months ended December 31, 2019. Additionally, this loss has not been included in the segment disclosure of Operating Earnings (Loss) for the Oil and Gas Proppants business, as disclosed in Footnote (P).
