At December 31, 2018 and 2017, leasehold improvements include approximately $6.6 million and $1.3 million, respectively, of lessor-paid tenant improvements for which the Company was deemed to be the accounting owner of the tenant improvements primarily because it was responsible for project cost overruns. Also, at December 31, 2017, construction in progress contained approximately $5.0 million of lessor-paid tenant improvements placed in service in 2018, for which the Company was deemed to be the accounting owner primarily because it was responsible for project cost overruns.

In both 2018 and 2017, the Company entered into leases for certain laboratory equipment which were capital leases. The leases had either a present value of expected payments in excess of 90% of the fair value of the equipment or a bargain purchase option at the end of the lease. As such, as of December 31, 2018 and 2017, the Company had approximately $1.3 million and $1.4 million, respectively, of assets under a capital lease having accumulated depreciation of approximately $0.9 million and $0.2 million, respectively.
