Paragraphs:
Other Income (Expense), Net
Interest expense decreased $54.7 million during fiscal 2019 as compared to fiscal 2018, primarily due to elimination of the non-recourse residential financing obligations in connection with the sale of the Residential Lease Portfolio in November 2018, as well as the elimination of the sales-leaseback financing obligations in connection with the sale of the commercial sale-leaseback portfolio during the first and second quarters of fiscal 2019.
Interest expense increased $17.7 million in fiscal 2018 as compared to fiscal 2017 primarily due to new debt and new commercial sale-leaseback arrangements.
Other income increased by $119.4 million during fiscal 2019 as compared to fiscal 2018, primarily due to a $158.3 million gain on an equity investment with readily determinable fair value in fiscal 2019, as compared to a loss of $6.4 million in fiscal 2018. Additionally, gain on sale of equity investments during fiscal 2019 was $17.7 million, compared to $54.2 million in fiscal 2018.
Other income increased by $143.0 million in fiscal 2018 as compared to fiscal 2017. The change is primarily due to a $54.2 million gain on the sale of our equity method investments in fiscal 2018, a $73.0 million impairment charge in fiscal 2017 in our 8point3 Energy Partners LP equity investment balance due to the adoption of ASC 606 which materially increased the investment balance and consequently, led to the recognition of an other-than-temporary impairment in the first quarter of fiscal 2017.
