The business substance of the purchase was to acquire Guangzhou New Spring Hospital Clinic (“New Spring Clinic”), which was a wholly owned subsidiary of New Spring Management located in downtown Guangzhou, to attract more patients for the Group’s self-built cancer hospital in the suburb of Guangzhou.

According to the agreement, the first to third instalment amounted to RMB7,560 in aggregate and was fully paid by MHM on the acquisition date, while the remaining RMB840 had been paid 6 months after the acquisition date as the original shareholder has fulfilled their obligation related to the acquisition.

Disposal of CHS

According to SPA, the share transfer price only included cash consideration of RMB 247,803, no other tangible or intangible assets, financial instruments or contingent consideration were specified. The cash consideration was firstly net off by settlement of the intercompany balance due from CHS of RMB602. The Group further paid a commission fee directly related to the transaction of RMB44,039, which was also accounted for a net off the cash consideration. Management evaluated the valuation of the retained 10% noncontrolling investment with the assistance of external valuer. As the transaction was not a related party transaction, the transfer price was considered a fair reflection of the 90% of the entity value. The valuer further considered the discount rate lack of control “DLOC” by comparing similar business combination cases in the same healthcare industry. The DLOC was finalized at 17% and the valuation of the retained noncontrolling investment was determined at RMB 22,925. There was no noncontrolling interest in CHS before the transaction. The carrying amount of the assets and liabilities of CHS was RMB235,714. With a foreign currency translation of RMB5,267, as a result, a loss on disposal of CHS of RMB14,894 was recognized in the consolidated statements of comprehensive loss for 2020.

This disposal does not represent a strategic shift on the Company’s major business and have no major effect on the Company’s results of operations, the disposal of the entity does not qualify as discontinued operation.

The breakdown of assets and liabilities as of November 19, 2020 (the disposal date), were as follows:


	RMB	US$
Current assets	4,909	752
Other non-current assets	257,368	39,443

Non-current liabilities	(539)	(83)
Net assets disposed	235,714	36,124

The breakdown of disposal loss are as summarized below:


	RMB	US$
Cash proceeds	247,803	37,977
Settlement of amount due from CHS	(602)	(92)
Commission fee	(44,039)	(6,749)
Fair value of retained noncontrolling investment	22,925	3,513
Disposition of net assets	(235,714)	(36,124)
Foreign currency translation	(5,267)	(808)
Loss on disposal of CHS	(14,894)	(2,283)

As the remaining investment only represented 10% voting shares in CHS and the Group did not retain any seats in board, management considered the Group in fact lost the ability to exercise significant influence over operating and financial policies of CHS. The remaining equity investment did not have readily determinable fair value, management elected to measure the remaining investment using measurement alternative at its cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. As at December 31, 2020, management determined there is no impairment indicator or any observable price change to the investment as the disposition date was near year end.
