Effective January 1, 2018, the Company adopted the provisions of ASU 2017-01 – “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”). ASU 2017-01 provides revised guidance to determine when an acquisition meets the definition of a business or alternatively should be accounted for as an asset acquisition. ASU 2017-01 requires that, when substantially all of the fair value of an acquisition is concentrated in a single identifiable asset or a group of similar identifiable assets, the asset or group of similar identifiable assets does not meet the definition of a business and therefore is required to be accounted for as an asset acquisition. Transaction costs will continue to be capitalized for asset acquisitions and expensed as incurred for business combinations. ASU 2017-01 will result in most, if not all, of the Company’s post-January 1, 2018 acquisitions being accounted for as asset acquisitions because substantially all of the fair value of the gross assets the Company acquires are concentrated in a single asset or group of similar identifiable assets. For asset acquisitions that are “owner occupied” (meaning that the seller either is the tenant or controls the tenant) the purchase price, including capitalized acquisition costs, will be allocated to land and building based on their relative fair values with no value allocated to intangible assets or liabilities. For asset acquisitions where there is a lease in place but not “owner occupied,” the Company will allocate the purchase price to tangible assets and any intangible assets acquired or liabilities assumed based on their relative fair values.

During the nine months ended September 30, 2018, the Company completed eight acquisitions. For all eight acquisitions, substantially all of the fair value of the acquisitions was concentrated in a single identifiable asset or group of similar identifiable assets and, therefore, all of the acquisitions represent asset acquisitions under the guidance provided by ASU 2017-01. Accordingly, transaction costs for these acquisitions were capitalized.

A rollforward of the gross investment in land, building and improvements as of September 30, 2018, resulting from these acquisitions is as follows:

 

 

Depreciation expense was $3,614 and $9,965 for the three and nine months ended September 30, 2018, respectively, and $2,176 and $5,372 for the three and nine months ended September 30, 2017, respectively.

 

As of September 30, 2018, the Company had aggregate capital improvement commitments to improve or expand existing tenant space of $17,003.  Many of these commitments are subject to contingencies that make it difficult to predict when such commitments will be called upon, if at all.  However, the Company expects to be obligated to spend approximately $721 in tenant improvements during 2018 (of which $521 was incurred as of September 30, 2018) in connection with its Sherman, Silvis, and Gainesville facilities.
