net investment in direct financing leases and sales-type leases .
teekay lng owns a 70 % ownership interest in teekay blt corporation -or the teekay tangguh joint venture which is a party to operating leases whereby the teekay tangguh joint venture leases two lng carriers -or the tangguh lng carriers to a third party which in turn leases the vessels back to the joint venture .
the time charters for the two tangguh lng carriers are accounted for as direct financing leases .
the tangguh lng carriers commenced their time charters with their charterers in 2009 .
in 2013 teekay lng acquired two 155900-cubic meter lng carriers the wilpride and wilforce from norway-based awilco lng asa -or awilco and chartered them back to awilco on five- and four-year fixed-rate bareboat charter contracts -plus a one-year extension option respectively with awilco holding a fixed-price purchase obligation at the end of the charters .
the bareboat charters with awilco were accounted for as direct financing leases .
however in june 2017 teekay lng agreed to amend the charter contracts with awilco to defer a portion of charter hire and extend the bareboat charter contracts and related purchase obligations on both vessels to december 2019 .
the amendments had the effect of deferring charter hire of between $ 10600 per day and $ 20600 per day per vessel from july 1 2017 until december 2019 with such deferred amounts added to the purchase obligation amounts .
as a result of the contract amendments both of the charter contracts with awilco were reclassified as operating leases upon the expiry of their respective original contract terms in november 2017 and august 2018 .
in september 2019 awilco exercised its option to extend both charters from december 31 2019 by up to 60 days with the ownership of both vessels transferring to awilco at the end of this extension .
in october 2019 awilco obtained credit approval for a financing facility that would provide funds necessary for awilco to satisfy its purchase obligation of the two lng carriers .
as a result both vessels were derecognized from the consolidated balance sheets and sales-type lease receivables were recognized based on the remaining amounts owing to teekay lng including the purchase obligations .
teekay lng recognized a gain of $ 14 .
3 million upon derecognition of the vessels for the year ended december 31 2019 which was included in write-down and loss on sale of vessels in the company ' s consolidated statements of loss -see note 19 .
awilco purchased both vessels in january 2020 -see note 24-a .
in addition the 21-year charter contract for the bahrain spirit floating storage unit -or fsu commenced in september 2018 and is accounted for as a direct finance lease .
the following table lists the components of the net investments in direct financing leases and sales-type leases : .
as at december 31 2019 estimated minimum lease payments to be received by teekay lng related to its direct financing and sales-type leases in each of the next five succeeding fiscal years were approximately $ 324 .

2 million -2022 $ 64 .
