note 17 2014 sales-type leases and financing receivables in april 2017 , in conjunction with the implementation of a new 201cgo-to-market 201d business model for the company's u.s .
dispensing business within the medication management solutions ( 201cmms 201d ) unit of the medical segment , the company amended the terms of certain customer leases for dispensing equipment within the mms unit .
the modification provided customers the ability to reduce its dispensing asset base via a return provision , resulting in a more flexible lease term .
prior to the modification , these leases were accounted for as sales-type leases in accordance with accounting standards codification topic 840 , "leases" , as the non- cancellable lease term of 5 years exceeded 75% ( 75 % ) of the equipment 2019s estimated useful life and the present value of the minimum lease payments exceeded 90% ( 90 % ) of the equipment 2019s fair value .
as a result of the lease modification , the company was required to reassess the classification of the leases due to the amended lease term .
accordingly , most amended lease contracts were classified as operating leases beginning in april 2017 .
the change in lease classification resulted in a pre-tax charge to earnings in fiscal year 2017 of $ 748 million , which was recorded in other operating expense , net .
beginning april 1 , 2017 , revenue associated with these modified contracts has been recognized on a straight-line basis over the remaining lease term , along with depreciation on the reinstated leased assets .
the company's consolidated financial results in 2018 and 2017 were not materially impacted by the financing receivables remaining subsequent to the lease modification discussed above .
