On January 8, 2015, CCT Funding LLC (“CCT Funding”), a wholly-owned Delaware limited liability company and subsidiary of Corporate Capital Trust, Inc., entered into an amendment (the “Fifth Amendment”) to its credit agreement (the “Credit Agreement”) with Deutsche Bank AG, New York Branch and the lenders referred to therein (the “Lenders”).

The Fifth Amendment further amends the Credit Agreement by providing for, among other things, (i) the termination of the Tranche B1 Commitment, Tranche B2 Commitment and Tranche D Commitment, and (ii) borrowings in an aggregate amount up to $150,000,000 on a committed basis (the “Tranche E Loans”). From and after February 11, 2015, the Fifth Amendment effective date, all outstanding loans, including Tranche B1 Loans and Tranche B2 Loans, shall be converted into Tranche E Loans.

The Fifth Amendment also modifies the interest rate and maturity date applicable to the Tranche E Loans under the Credit Agreement. The Tranche E Loans under the Credit Agreement will generally bear interest based on a three-month adjusted London interbank offered rate (“Adjusted LIBOR”) for the relevant interest period plus a spread of 1.85% per annum, payable monthly in arrears. Pursuant to the Fifth Amendment, the Tranche E Loans are scheduled to mature, and all accrued and unpaid interest thereunder will be due and payable on February 8, 2017. Upfront fees and unfunded commitment fees were also incurred with respect to the Tranche E Loans.

The foregoing description of the Fifth Amendment in this Item 1.01 does not purport to be complete in scope and is qualified in its entirety by the full text of the Fifth Amendment and the full text of the previously filed Credit Agreement (including the first, second, third and fourth amendments thereto).

The information included under Item 1.01 above is incorporated by reference into this Item 2.03.

As of the date of this filing, CCT Funding has repaid in full all principal amounts previously borrowed under the Credit Agreement’s credit facility.
