[1] The Company completed its leasehold improvement for its new Ningbo office in June, 2018. The Company subsequently entered into a renegotiation of the lease term with the lessor and the leasehold improvement is subject to inspection and approval by the lessor. The office is not currently in use and thus no amortization expense for the leasehold improvement was recorded for the period ended December 31, 2018.
