Construction in Progress

Construction in progress represents assets that are not ready for service or are in the construction stage. Assets are depreciated based on the estimated useful life of the asset once it is placed in service.

Impairment of Property, Plant and Equipment

The Company reviews and evaluates its long-lived assets for impairment on an annual basis or more frequently when events or changes in circumstances indicate that the related carrying amounts may not be recoverable.  As of December 31, 2023, the Company performed a recoverability test pursuant to ASC 360, primarily due to recent market trends in the graphite market and determined that there was no impairment.  For the years ended December 31, 2023 and 2022, no impairment charges were recorded on the Company’s assets.

Land Addition

On June 22, 2021, AGP entered into incentive agreements with the State of Alabama and local municipalities for the siting of the Kellyton Graphite Plant. The incentive agreements provide certain tax credits and incentives under the Alabama Jobs Act in connection with the construction of the processing facility. Additionally, in connection with and in contemplation of the incentive agreements, on July 23, 2021, AGP entered into a land lease with the Lake Martin Area Industrial Development Authority. The lease provides AGP rights to approximately 70 acres to construct and operate its commercial graphite processing facility in Coosa County, Alabama. The lease has a term of 10-years, a nominal lease

payment, and transfer of title to AGP at the end of the lease term. Further, the lease provides AGP the option to purchase the land for a nominal amount during the term of the lease. The incentive agreements and the lease are accounted for by the Company as a government grant; whereby the Company realized the fair value of the land of $1.4 million as an increase to Property, plant, and equipment with a corresponding obligation recorded in Other long-term liabilities in the consolidated balance sheet at December 31, 2023.  The $1.4 million recognized represents the fair value of the land at the time of lease inception in 2021. The land represents a non-depreciable asset on the Company’s consolidated balance sheet. The corresponding obligation recorded in Other long-term liabilities on the consolidated balance sheet will be amortized to other income over the life of the Kellyton Graphite Plant once placed in service.
