charters-in .
as of december 31 2019 the company had commitments to charter-in 11 vessels which are all bareboat charters .
during the second quarter of 2019 the company commenced a bareboat charter for the overseas key west for a lease term of 10 years .
based on the length of the lease term and the remaining economic life of the vessel it is accounted for as a finance lease .
the remaining 10 chartered-in vessels are accounted for as operating leases .
the right-of-use asset accounted for as a finance lease arrangement is reported in vessels and other property less accumulated depreciation on our consolidated balance sheets .
the company holds options for 10 of the vessels chartered-in that can be exercised for one three or five years with the one-year option only usable once while the three- and five-year options are available indefinitely .
the lease payments for the charters-in are fixed throughout the option periods and the options are on a vessel-by-vessel basis that can be exercised individually .
the company exercised its option on one of its vessels to extend the term until june 2025 .
on december 10 2018 the company exercised its options to extend the terms of the other nine vessels .
terms for five of the vessels were extended for an additional three years with terms ending in december 2022 and terms for four of the vessels were extended for an additional year with terms ending december 2020 .
on december 11 2019 the terms for the four vessels ending december 2020 were extended for an additional three years with terms ending in december 2023 .
five of the company ' s chartered in vessels contain a deferred payment obligation - “ dpo ” which relates to charter hire expense incurred by the company in prior years and payable to the vessel owner in future periods .
this dpo is due in quarterly installments with the final quarterly payment due upon lease termination .
the future minimum commitments under these leases are as follows : .
the bareboat charters-in provide for variable lease payments in the form of profit share to the owners of the vessels calculated in accordance with the respective charter agreements or based on time charter sublease revenue .
because such amounts and the periods impacted are not reasonably estimable they are not currently reflected in the table above .
due to reserve funding requirements and current rate forecasts no profits are currently expected to be paid to the owners in respect of the charter term within the next year .
