Decrease in Public Offering Price

        On September 29, 2015, we decreased our public offering price from $9.00 per share to $8.75 per share. The decrease in the public offering price was effective as of the Company's September 30, 2015 weekly closing and first applied to subscriptions received from September 23, 2015 through September 29, 2015. In accordance with our share pricing policy, our board of trustees determined that a reduction in the public offering price per share was warranted following a decline in our net asset value per share to an amount more than 2.5% below our then-current net offering price.
