"With nearly two-thirds of our capitalization derived from unsecured debt and equity, we are in a strong position to effectively fund our business needs during the economic downturn and through to the eventual recovery." In addition to various risk management and monitoring tools, Ares Capital's investment adviser grades the credit risk of all investments on a scale of 1 to 4 no less frequently than quarterly. This system is intended primarily to reflect the underlying risk of a portfolio investment relative to Ares Capital's initial cost basis in respect of such portfolio investment (i.e., at the time of origination or acquisition), although it may also take into account under certain circumstances the performance of the portfolio company's business, the collateral coverage of the investment and other relevant factors.
