Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments At March 31, 2019, the Company had outstanding performance bonds totaling $556,000. As a lessor, the Company had $95.1 million in future obligations under leases to fund tenant improvements and other future construction obligations at March 31, 2019. As a lessee, the Company had future obligations for other operating leases of $449,000 at March 31, 2019. Litigation On May 1, 2019, a purported TIER stockholder filed a putative stockholder class action against TIER and the members of the TIER board of directors challenging the disclosures made in connection with the Merger. The lawsuit is captioned Martin v. TIER REIT, INC., et al., No. 1:19-CV-01292, and is pending in the United States District Court for the District of Maryland. On May 3, 2019, a purported TIER stockholder filed a putative stockholder class action against TIER, the members of the TIER board of directors, and the Company also challenging the disclosures made in connection with the Merger. The lawsuit is captioned Franchi v. TIER REIT, Inc. et al., No. 1:19-CV-01310, and is also pending in the United States District Court for the District of Maryland. The complaints generally allege that the registration statement filed in connection with the Merger of which this joint proxy statement/prospectus forms a part fails to disclose certain allegedly material information in violation of Section 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder. The alleged omissions relate to (i) the existence of certain provisions in confidentiality agreements entered into between TIER and alternative bidders during the strategic sales process; (ii) certain financial projections and GAAP reconciliations for TIER and the Company; and (iii) certain financial analyses performed by TIER's financial advisor. Plaintiffs seek to enjoin the Defendants from proceeding with the Merger and seek damages in the event the transaction is consummated. TIER and the Company are reviewing the complaints and have not yet formally responded to them, but believe that Plaintiffs' allegations are without merit and intend to defend against them vigorously. However, litigation is inherently uncertain and there can be no assurance regarding the likelihood that TIER's and the Company's defense of the actions will be successful. Accordingly, at this time, the Company is not able to determine if the outcome of these matters will have a material adverse effect on the liquidity, results of operations, business, or financial condition of the Company. Additional lawsuits arising out of the Merger may also be filed in the future. The Company is subject to various other legal proceedings, claims, and administrative proceedings arising in the ordinary course of business, some of which are expected to be covered by liability insurance. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters using the latest information available. The Company records a liability for litigation if an unfavorable outcome is probable and the amount of loss or range of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, the Company accrues the best estimate within the range. If no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount within the range. If an unfavorable outcome is probable but the amount of the loss cannot be reasonably estimated, the Company discloses the nature of the litigation and indicates that an estimate of the loss or range of loss cannot be made. If an unfavorable outcome is reasonably possible and the estimated loss is material, the Company discloses the nature and estimate of the possible loss of the litigation. The Company does not disclose information with respect to litigation where an unfavorable outcome is considered to be remote or where the estimated loss would not be material. Based on current expectations, such matters, both individually and in the aggregate, are not expected to have a material adverse effect on the liquidity, results of operations, business or financial condition of the Company.
