(the “Company”) is a fully integrated office real estate investment trust (“REIT”) that owns, develops, acquires, leases and manages properties primarily in the best business districts of Atlanta, Charlotte, Dallas, Nashville, Orlando, Pittsburgh, Raleigh, Richmond and Tampa. The Company conducts its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At June 30, 2022, we owned or had an interest in 27.6 million rentable square feet of in-service properties, 0.6 million rentable square feet of office properties under development and development land with approximately 4.9 million rentable square feet of potential office build out. Capital Structure The Company is the sole general partner of the Operating Partnership. At June 30, 2022, the Company owned all of the Preferred Units and 104.8 million, or 97.7%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.5 million Common Units. During the six months ended June 30, 2022, the Company redeemed 30,909 Common Units for a like number of shares of Common Stock. During 2020, we entered into separate equity distribution agreements in which the Company may offer and sell up to $300.0 million in aggregate gross sales price of shares of Common Stock. During the six months ended June 30, 2022, the Company issued 130,011 shares of Common Stock under its equity distribution agreements at an average gross sales price of $46.50 per share and received net proceeds, after sales commissions, of $6.0 million. Basis of Presentation Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company’s Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership’s Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. We consolidate joint venture investments, such as interests in partnerships and limited liability companies, when we control the major operating and financial policies of the investment through majority ownership, in our capacity as a general partner or managing member or through some other contractual right. At June 30, 2022, we have involvement with, and are the primary beneficiary in, an entity that we concluded to be a variable interest entity. As such, this entity is consolidated. Additionally, at June 30, 2022, we have involvement with, but are not the primary beneficiary in, an entity that we concluded to be a variable interest entity. As such, this entity is not consolidated. (See Note 3). All intercompany transactions and accounts have been eliminated. The unaudited interim consolidated financial statements and accompanying unaudited consolidated financial information, in the opinion of management, contain all adjustments (including normal recurring accruals) necessary for a fair presentation of our financial position, results of operations and cash flows. We have condensed or omitted certain notes and other information from the interim Consolidated Financial Statements presented in this Quarterly Report as permitted by SEC rules and regulations. These Consolidated Financial Statements should be read in conjunction with our 2021 Annual Report on Form 10-K. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates. Insurance We are primarily self-insured for health care claims for participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. At June 30, 2022, a reserve of $0.5 million was recorded to cover estimated reported and unreported claims. Planned Investment Activity During the second quarter of 2022, we agreed to acquire 650 South Tryon at Legacy Union in Charlotte’s Uptown CBD submarket for a total investment of $203.0 million, including $3.9 million of anticipated leasing capital expenditures to bring the property to stabilization. 650 South Tryon, which delivered in late 2020 and is currently 79% leased, is a trophy, LEED gold-certified office building encompassing 367,000 square feet. 650 South Tryon is immediately adjacent and connected to Company-owned Bank of America Tower at Legacy Union, a trophy, LEED gold-certified office building encompassing 841,000 square feet that delivered in 2019. The acquisition of 650 South Tryon is scheduled to close in August 2022. We have posted earnest money deposits totaling $37.5 million that are non-refundable except in limited circumstances. Recently Issued Accounting Standards The Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) that provides temporary optional expedients and exceptions to the guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). Entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Entities can also elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. The guidance in this ASU is optional and may be elected now through December 31, 2022 as reference rate reform activities occur. We will continue to evaluate the impact of this ASU; however, we currently expect to avail ourselves of such optional expedients and exceptions should our modified contracts meet the required criteria.
