(1) | Included in construction in progress are costs for projects in progress to upgrade or refurbish certain rigs in our existing fleet. Additionally, we include other capital maintenance purchase-orders that are open/in process. As these various projects are completed, the costs are then classified to their appropriate useful life category.
Impairments - Fiscal Year 2020 Consistent with our policy, we evaluate our drilling rigs and related equipment for impairment whenever events or changes in circumstances indicate the carrying value of these assets may exceed the estimated undiscounted future net cash flows. Our evaluation, among other things, includes a review of external market factors and an assessment on the future marketability of specific rigs’ asset group. During the second quarter of fiscal year 2020, several significant economic events took place that severely impacted the current demand on drilling services, including the significant drop in crude oil prices caused by OPEC+'s price war coupled with the decrease in the demand due to the COVID-19 pandemic. To maintain a competitive edge in a challenging market, the Company’s management introduced a new strategy focused on operating various types of highly capable upgraded rigs and phasing out the older, less capable fleet. This resulted in grouping the super-spec rigs of our legacy Domestic FlexRig® 3 asset group and our FlexRig® 5 asset group creating a new "Domestic super-spec FlexRig®" asset group, while combining the legacy Domestic conventional asset group, FlexRig® 4 asset group and FlexRig® 3 non-super-spec rigs into one asset group (Domestic non-super-spec asset group). Given the current and projected low utilization for our Domestic non-super-spec asset group and all International asset groups, we considered these economic factors to be indicators that these asset groups may be impaired. As a result of these indicators, we performed impairment testing at March 31, 2020 on each of our Domestic non super-spec and International conventional, FlexRig® 3, and FlexRig® 4 asset groups, which had an aggregate net book value of $605.8 million. We concluded that the net book value of each asset group is not recoverable through estimated undiscounted cash flows and recorded a non-cash impairment charge of $441.4 million in the Consolidated Statement of Operations for the fiscal year ended September 30, 2020. Of the $441.4 million total impairment charge recorded, $292.4 million and $149.0 million was recorded in the North America Solutions and International Solutions segments, respectively. No further impairments were recognized in fiscal year 2020. Impairment was measured as the amount by which the net book value of each asset group exceeds its fair value. The most significant assumptions used in our undiscounted cash flow model include timing on awards of future drilling contracts, drilling rig utilization, estimated remaining useful life, and net proceeds received upon future sale/disposition. These assumptions are classified as Level 3 inputs by ASC Topic 820 Fair Value Measurement and Disclosures as they are based upon unobservable inputs and primarily rely on management assumptions and forecasts. In determining the fair value of each asset group, we utilized a combination of income and market approaches. The significant assumptions in the valuation are based on those of a market participant and are classified as Level 2 and Level 3 inputs by ASC Topic 820 Fair Value Measurement and Disclosures. As of March 31, 2020, the Company also recorded an additional non-cash impairment charge related to in-progress drilling equipment and rotational inventory of $44.9 million and $38.6 million, respectively, which had aggregate book values of $68.4 million and $38.6 million, respectively, in the Consolidated Statement of Operations for the fiscal year ended September 30, 2020. Of the $83.5 million total impairment charge recorded for in-progress drilling equipment and rotational inventory, $75.8 million and $7.7 million was recorded in the North America Solutions and International Solutions segments, respectively. Impairment - Fiscal Year 2019 During the third quarter of fiscal year 2019, the Company's management performed a detailed assessment, considering a number of approaches, to maximize the utilization and enhance the margins of the domestic and international FlexRig® 4 asset groups. In June 2019, this assessment concluded that marketing a smaller fleet of these two asset groups would provide the best economic outcome. As such, the decision was made to downsize the number of domestic and international FlexRig® 4 drilling rigs, to be marketed to our customers, from 71 rigs to 20 domestic rigs and from 10 rigs to 8 international rigs and utilize the major interchangeable components of the decommissioned drilling rigs within these asset groups as capital spares for all of our remaining rig fleet. This reduced the aggregate net book values of the FlexRig® 4 asset groups as of June 30, 2019 from $317.8 million to $107.5 million for domestic rigs and from $55.7 million to $47.8 million for international rigs. Following the downsizing process, we performed a detailed study to optimize the quantities of capital spares and drilling support equipment required to support the future operations of our rig fleet going forward. These decisions and analysis resulted in a write down of excess capital spares and drilling support equipment, which had an aggregate net book value of $235.3 million, to their estimated proceeds to ultimately be received on sale or disposal based on our historical experience with sales and disposals of similar assets, resulting in an impairment of $224.3 million, which was recorded in our Consolidated Statement of Operations for the fiscal year ended September 30, 2019. Of the $224.3 million total impairment charge recorded, $216.9 million and $7.4 million was recorded in our North America Solutions and International Solutions segments, respectively. The significant assumptions in the valuation are classified as Level 2 inputs by ASC Topic 820, Fair Value Measurement and Disclosures. Due to the downsizing of our domestic and international FlexRig® 4 asset groups, at June 30, 2019, we performed impairment testing on these two asset groups. We concluded that the net book values of the asset groups are recoverable through estimated undiscounted cash flows with a surplus. The most significant assumptions used in our undiscounted cash flow model include timing on awards of future drilling contracts, operating dayrates, operating costs, rig reactivation costs, drilling rig utilization, estimated remaining useful life, and net proceeds received upon future sale/disposition. The assumptions are consistent with the Company's internal forecasts for future years. Although we believe the assumptions used in our analysis are reasonable and appropriate and the probability-weighted average of expected future undiscounted net cash flows exceed the net book value for each of the domestic and international FlexRig® 4 asset groups as of June 30, 2019, different assumptions and estimates could materially impact the analysis and our resulting conclusion. Impairments - Fiscal Year 2018 During the fourth quarter of fiscal year 2018, after ceasing operations in Ecuador, we entered into a sales negotiation with respect to the six conventional rigs, within a separate international conventional rigs’ asset group, with net book values of $20.8 million, present in the country, pursuant to which the rigs, together with associated equipment and machinery, were sold to a third party to be recycled. Certain components of these rigs, with an $8.5 million net book value, that were not subject to the sale agreement were transferred to the United States to be utilized on other FlexRig® drilling rigs with high activity and demand. The sales transaction was completed in November 2018. We recorded a non-cash impairment charge within our International Solutions segment of $9.2 million, which is included in Asset Impairment Charge on the Consolidated Statement of Operations for the fiscal year ended September 30, 2018. As a result, the remaining rig within the same asset group, not to be disposed of, was written down resulting in an additional impairment charge of $1.4 million. The assets were recorded at fair value based on the sales agreement and as such are classified as Level 2 within the fair value hierarchy. Furthermore, during the fourth quarter of fiscal year 2018, within our North America Solutions segment, management committed to a plan to auction several previously decommissioned rigs during fiscal year 2019. As a result, we wrote them down to their estimated fair values. We recorded a non-cash impairment charge of $5.7 million, which is included in Asset Impairment Charge on the Consolidated Statements of Operations for the fiscal year ended September 30, 2018. The assets were recorded at fair value based on the auction price and as such are classified as Level 2 of the fair value hierarchy. Decommissioning While the crude oil market imbalance is a global phenomenon, it has more acutely impacted the U.S. market as a result of storage limitations during the last two quarters of fiscal year 2020. The abruptness of and the overall size of the decrease in demand for refined products, such as gasoline and diesel, has created an abundance of supply for such products which has caused the inventory levels of crude oil and its related refined products to become greatly elevated, reaching the high end of storage capabilities. This has greatly reduced the need, or in some cases, entirely eliminated the ability of refineries to use crude oil as a feedstock. As such, exploration and production ("E&P") companies, our customers, may have limited opportunities to offload their production and even then, the selling price could be at very low, uneconomical prices. Consequently, some E&P companies have chosen to shut-in and stop production, not complete additional wells drilled and/or not drill any more wells until the market imbalance corrects and it is economical to resume production and drilling wells. During the fiscal year ended September 30, 2020, we decommissioned two rigs and 35 rigs from our legacy Domestic Conventional asset group and FlexRig® 3 asset group, respectively. The decommissioned rigs were impaired as of March 31, 2020. Depreciation Depreciation in the Consolidated Statements of Operations of $474.7 million, $556.9 million and $578.4 million includes abandonments of $4.0 million, $11.4 million and $27.7 million for fiscal years 2020, 2019 and 2018, respectively. Gain on Sale of Assets We had a gain on sale of assets of $46.8 million, $39.7 million and $22.7 million in fiscal years 2020, 2019 and 2018, respectively. These gains were related to customer reimbursement for the replacement value of drill pipe damaged or lost in drilling operations. Additionally, during the fiscal year ended September 30, 2020, we closed on the sale of a portion of our real estate investment portfolio, including six industrial sites, for total consideration, net of selling related expenses, of $40.7 million and an aggregate net book value of $13.5 million, resulting in a gain of $27.2 million, which is included within Gain on Sale of Assets on our Consolidated Statement of Operations.
