The amount of distributions HTA pays to its stockholders is determined by HTA’s board of directors, at its discretion, and is dependent on a number of factors, including funds available for the payment of distributions, HTA’s financial condition, capital expenditure requirements and annual distribution requirements needed to maintain HTA’s status as a real estate investment trust, or REIT, under the Internal Revenue Code. HTA’s board of directors may reduce its distribution rate and HTA cannot guarantee the amount of distributions paid in the future, if any.
