Land Lease and Purchase Options
        We hold lease and purchase option agreements (the “Options”) for certain tracts of land and associated river frontage. Upon exercise of the Options, the leases are subject to maximum terms of 50 years, inclusive of various renewals which are at our sole discretion. Costs of the Options will be amortized over the life of the lease once obtained, or capitalized into the land if purchased.
Permitting Costs
        Permitting costs primarily represent the purchase of wetland credits in connection with our permit application to the USACE in 2017 and 2018. These wetland credits will be applied to our permit in accordance with the Clean Water Act and the Rivers and Harbors Act, which require us to mitigate the impact to Louisiana wetlands caused by the construction of the Driftwood Project. In May 2019, we received the USACE permit. The permitting costs will be transferred to construction in progress upon reaching FID.
