⁽¹⁾ In accordance with ASC 842, a tenant allowance should be included in the measurement of the consideration in the lease agreement at inception and reflected as a reduction to the right-of-use asset and a corresponding reduction to the right-use-liability if the lessee both controls the construction of the tenant improvements and the expects to fully earn all of the tenant allowance. OpGen has met both conditions at the inception of its Rockville, Maryland lease and has recorded the Tenant Improvement Allowance accordingly. As the cash for the Tenant Improvement Allowance is received from the lessor under the terms of the Rockville, Maryland lease, the corresponding right-of-use liability will increase and will be amortized as part of the right-of use asset and liability amortization over the term of the Rockville, Maryland Lease in accordance with ASC 842.
