Certain Information About Distributions

The determination of the tax attributes of FSIC III’s distributions is made annually as of the end of its fiscal year based upon its taxable income and distributions paid, in each case, for the full year. Therefore, a determination made on a quarterly basis may not be representative of the actual tax attributes of FSIC III’s distributions for a full year. FSIC III intends to update stockholders quarterly with an estimated percentage of its distributions that resulted from taxable ordinary income. The actual tax characteristics of distributions to stockholders will be reported to stockholders annually on Form 1099-DIV.

The payment of future distributions on FSIC III’s shares of common stock is subject to the sole discretion of its board of directors and applicable legal restrictions and, therefore, there can be no assurance as to the amount or timing of any such future distributions.

FSIC III may fund its cash distributions to stockholders from any sources of funds legally available to it, including expense reimbursements from FS Investments, as well as offering proceeds, 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. FSIC III has not established limits on the amount of funds it may use from available sources to make distributions. There can be no assurance that FSIC III will be able to pay distributions at a specific rate or at all.
