Deposits Related to Marketing Activities

Tellurian has made advances to trade conferences and similar events for networking, marketing and public relations in the ordinary course of its development activities. These deferred costs relate primarily to conference fees, travel accommodations and similar event-specific arrangements, which are required to be paid in advance. General marketing and advertising costs not associated with specific events currently are expensed, and costs that are event-specific are deferred and expensed when the event occurs.

Land Lease and Purchase Options

The Company, through its wholly owned subsidiary Driftwood LNG, holds lease and purchase option agreements (the “Options”) for certain tracts of land and associated river frontage that provide for four or five-year terms. In addition to the Options, the Company holds a ground lease for a port facility adjacent to a tract of land that was acquired in March 2016. The lease provides for a four-year term, subject to a 20-year extension and six five-year renewals and is accounted for as an operating lease, with rental payments accounted for using the straight-line method.

Upon exercise of the Options, the leases are subject to maximum terms of 60 years (inclusive of various renewals) at the option of the Company. Lease and purchase option payments have been capitalized in other non-current assets. Costs of the lease and purchase options will be amortized over the life of the lease once obtained, or capitalized into the land if purchased. If no lease or land is obtained, the Options cost will be expensed.

Office Leases

The Company holds a ten-year lease for its corporate headquarters located in Houston, Texas as well as leases for other offices in the U.S., London and Singapore. The leases are accounted for as operating leases, with rental payments accounted for using the straight-line method. Where payments exceed or are less than the amount of rent expense recognized, prepaid rent or deferred rent payable, respectively, is recognized on the Condensed Consolidated Balance Sheets.
