NOTE 3 — PROPERTY, PLANT AND EQUIPMENT
Property, plant and equipment is comprised of fixed assets and natural gas properties, as shown below (in thousands):
Depreciation and depletion expenses for the years ended December 31, 2020, 2019 and 2018 were approximately $17.2 million, $20.4 million and $1.5 million, respectively.
We own land in Louisiana for the purpose of constructing the Driftwood Project.
Proved Properties Impairment
The carrying values of our proved natural gas properties are reviewed for impairment when events or circumstances indicate that the remaining carrying value may not be recoverable. During the second quarter of 2020, there were indicators that the carrying values of certain of our properties may be impaired as a result of depressed natural gas prices and a decline in demand for natural gas. We determined that these adverse market conditions represented a triggering event to perform an impairment assessment of our proved natural gas properties.
To determine whether impairment had occurred, we compared the estimated expected undiscounted future cash flows from our natural gas properties to the carrying values of those properties. The estimated future cash flows used in the recoverability test are based on proved and, if determined reasonable by management, risk-adjusted probable and possible reserves and assumptions generally consistent with those used by us for internal planning and budgeting purposes. These include, among other things, the intended use of the asset, anticipated production from reserves, future market prices of natural gas adjusted for basis differentials, and future operating costs. Proved properties that have carrying amounts in excess of estimated future undiscounted cash flows are written down to fair value.
During the second quarter of 2020, we recognized an impairment charge of approximately $81.1 million primarily associated with our assets located in northern Louisiana. The impairment charge was recorded as a reduction to the assets’ carrying values to their estimated fair values of approximately $28.7 million. The estimated fair value of the impaired assets, as determined as of June 30, 2020, was based on significant inputs that are not observable in the market and, as such, are considered a Level 3 fair value measurement. Key assumptions included in the calculation of the fair value included values for the following: (i) reserves, (ii) future commodity prices and (iii) future operating and development costs.
On September 10, 2019 (the “Sale Closing Date”), we sold our wholly owned subsidiary, Magellan Petroleum (UK) Investments Holdings Limited (“Magellan Petroleum UK”), to a third party for approximately $14.8 million. The assets and liabilities of Magellan Petroleum UK consisted predominantly of non-operated interests in the Weald Basin, United Kingdom. The sale of Magellan Petroleum UK generated an overall gain of approximately $4.2 million, all of which was recognized in 2019 as Other income, net in our Consolidated Statements of Operations.
The entire disclosure for long-lived, physical asset used in normal conduct of business and not intended for resale. Includes, but is not limited to, work of art, historical treasure, and similar asset classified as collections.
