Total depreciation expense was $3.4 million and $13.5 million for the three months ended September 30, 2023 and 2022, respectively and $10.4 million and $21.7 million for the nine months ended September 30, 2023 and 2022, respectively.

On January 30, 2023, Greenidge entered into an agreement regarding its 2021 and 2022 Master Equipment Finance Agreements with NYDIG. During the nine months ended September 30, 2023, the Company transferred ownership of bitcoin mining equipment with net book value of $50.0 million and miner deposits of $7.4 million that remained accrued to Greenidge for previous purchases of mining equipment with a bitcoin miner manufacturer and the related debt was canceled pursuant to a debt settlement agreement entered into with NYDIG. There was no gain or loss recognized on the sales as these assets. The Company recognized a gain on the sale of assets of $1.8 million, which primarily related to the sale of bitcoin miner manufacturer coupons, including $1.2 million that were transferred as part of the debt restructuring agreement with NYDIG.

Impairment

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine recoverability of a long-lived asset, management evaluates whether the estimated future undiscounted net cash flows, based on prevailing market conditions, from the asset are less than its carrying amount. If impairment is indicated, the long-lived asset is written down to fair value.

The Company evaluated the recoverability of the South Carolina facility classified as Held for Sale (see note 3, Assets Held for Sale and Discontinued Operations) as of September 30, 2023. The Company is evaluating future uses of the remaining real estate assets in South Carolina, which includes the land and the original building which was classified as construction in process as it was not used in cryptocurrency mining. The impairment assessment was performed using a market approach. An impairment charge of $4 million was recorded for the three month period ended September 30, 2023, which is the remaining value of the building which was determined to no longer be recoverable.

During the nine months ended September 30, 2022, as a result of the significant reduction in the price of bitcoin and increased energy prices during 2022, the Company’s results of operations, as well as income expectations, were negatively impacted resulting in the recognition of noncash impairment charges of $71.5 million to reduce the net book value of the long-lived assets to fair value.

Fair value was determined utilizing the market approach, relying on the guideline public company method. Our guideline public company method incorporates revenue and hash rate multiples from other publicly traded companies with operations and other characteristics similar to Greenidge.
