Certain Information About Distributions

The determination of the tax attributes of the Company's distributions will be made annually as of the end of the Company's fiscal year based upon its taxable income and distributions paid, in each case, for the full year. Therefore, a determination as to the tax attributes of the distributions made on an interim basis may not be representative of the actual tax attributes for a full year. The Company intends to update shareholders quarterly with an estimated percentage of its distributions that resulted from taxable ordinary income. The actual tax characteristics of distributions to shareholders will be reported to shareholders annually on Form 1099-DIV. The payment of future distributions on the Company's common shares is subject to the discretion of the Board and applicable legal restrictions and, therefore, there can be no assurance as to the amount or timing of any such future distributions.

The Company may fund its cash distributions to shareholders from any sources of funds legally available to it, including borrowings, net investment income from operations, capital gains proceeds from the sale of assets, non-capital gains proceeds from the sale of assets and dividends or other distributions paid to it on account of preferred and common equity investments in portfolio companies. The Company has not established limits on the amount of funds it may use from available sources to make distributions. There can be no assurance that the Company will be able to pay distributions at a specific rate or at all.
