In April 2021, we announced the sale of our corporate headquarters located in Sunnyvale, California, consisting primarily of land, buildings and improvements, for cash proceeds of $365 million. The assets sold had a net book value totaling $210 million. To facilitate an orderly transition to a new location, we executed short-term lease agreements with the buyer to lease back these properties. The agreed lease payments were below market rates and as a result we recognized an asset of $7 million for the difference between the fair value of the leases and the agreed lease payments. The cash proceeds, less direct selling costs, plus the fair value of the below-market leases, resulted in a net gain on the sale of these properties of $156 million.

In September 2017, we entered into an agreement to sell certain land and buildings located in Sunnyvale, California through two separate and independent closings. The first closing occurred in fiscal 2018. On August 26, 2019, the second closing occurred and we consummated the sale of the land, with a net book value of $53 million, and received cash proceeds of $96 million, resulting in a gain, net of direct selling costs, of $38 million.

During fiscal 2019, we formed a joint venture with Lenovo (Beijing) Information Technology Ltd. (“Lenovo”) in China and, in February 2019, contributed assets to the newly formed entity, Lenovo NetApp Technology Limited (“LNTL”), in exchange for a non-controlling 49% equity interest. The group of assets we contributed and derecognized met the definition of a business and included cash, fixed assets, customer relationships and an allocation of goodwill, with an aggregate book value of $7 million. The fair value of our equity interest in LNTL of $80 million, based on discounted cash flows, resulted in a non-cash gain of $73 million. We accounted for our ownership interest as an equity method investment and have presented it in other non-current assets on our consolidated balance sheets. The book value of our investment as of April 30, 2021 and April 24, 2020 was $71 million and $67 million, respectively. The book value as of April 24, 2020 reflected a $10 million other-than-temporary impairment charge recorded to other (expense) income, net in the fourth quarter of fiscal 2020 attributable to a decline in growth rate projections for LNTL, in part due to the COVID-19 pandemic.

LNTL is integral to our sales channel strategy in China, acting as a distributor of our offerings to customers headquartered there, and involved in certain OEM sales to Lenovo. It will also endeavor to localize our products and services, and to develop new joint offerings for the China market by leveraging NetApp and Lenovo technologies.
