"LEVEL II STATUS" exists at any date if, at such date, the Borrower's long-term debt is rated A-/A3 or higher by at least two Rating Agencies and (ii) Level I Status does not exist at such date. "LEVEL III STATUS" exists at any date if, at such date, the Borrower's long-term debt is rated BBB+/Baa1 or higher by at least two Rating Agencies and (ii) neither Level I Status nor Level II Status exists at such date. "LEVEL IV STATUS" exists at any date if, at such date, the Borrower's long-term debt is rated BBB/Baa2 or higher by at least two Ratings Agencies and (ii) none of Level I Status, Level II Status, Level III Status exists at such date. "LEVEL V STATUS" exists at any date if, at such date, the Borrower's long-term debt is rated BBB-/Baa3 or higher by at least two Rating Agencies and (ii) none of Level I Status, Level II Status, Level III Status or Level IV Status exists as such date. 8 "LEVEL VI STATUS" exists at any date, if at the close of business on such date, none of Level I Status, Level II Status, Level III Status, Level IV Status or Level V Status exists. "PRICING" refers to the determination of which of Level I Pricing, Level II Pricing, Level III Pricing, Level IV Pricing, Level V Pricing or Level VI Pricing applies at any date. "STATUS" refers to the determination of which of Level I Status, Level II Status, Level III Status, Level IV Status, Level V Status or Level VI Status exists at any date. The "USAGE" applicable to any date is the percentage equivalent of a fraction the numerator of which is the aggregate outstanding principal amount of the Loans at such date and the denominator of which is the aggregate amount of the Commitments at such date. If for any reason any Loans remain outstanding following the termination of the Commitments, Usage will be deemed to be 25% or more. The credit ratings to be utilized for purposes of determining a Status hereunder are those assigned to the senior unsecured debt of the Borrower without third-party credit enhancement, and any rating assigned to any other debt of the Borrower shall be disregarded; provided that if at any time the Borrower's senior unsecured debt is rated by exactly two Rating Agencies and the ratings assigned to such debt by such two Rating Agencies are more than one full rating category apart, Status shall be determined based on a rating one category higher than the lower of such two ratings (e.g., if the S&P rating is A+, the Moody's rating is Baa1 and there is no D&P rating, then Level II Status shall exist); provided further that if at any time the Borrower's senior unsecured debt, without third party credit enhancement, is not rated by at least two Rating Agencies, then Status shall be Level VI Status. The rating in effect at any date is that in effect at the close of business on such date.
