Item 2.03. Creation of a Direct Financial Obligation.

As previously reported on a Form 8-K filed on September 10, 2013, Corporate Capital Trust (the “Company”) entered into a senior secured revolving credit agreement dated September 4, 2013 (the “Credit Agreement”). The Credit Agreement currently provides for a revolving credit facility (the “Revolving Credit Facility”) consisting of loans to be made in US dollars and other foreign currencies in an initial aggregate amount of $320 million. Pursuant to a Guarantee and Security Agreement entered into among the Company, JPMorgan Chase Bank, N.A. (in its capacity as administrative agent and in its capacity as collateral agent) and the other parties thereto (the “Guarantee and Security Agreement”), the Revolving Credit Facility is secured by all of the Company’s portfolio investments, its cash and its securities accounts (in each case, subject to certain exclusions), and provides for a guaranty by certain subsidiaries of the Company. The Revolving Credit Facility includes an “accordion” feature that allows the Company, under certain circumstances, to increase the size of the facility to a maximum of $600 million.

On April 4, 2014, (the “Increase Date”) pursuant to the Credit Agreement, the Company entered into an agreement (the “Commitment Increase Agreement”) with JPMorgan Chase Bank, N.A. (in its capacity as administrative agent) to increase the aggregate amount of the Revolving Credit Facility by $170 million for a total Revolving Credit Facility size of $490 million as of the Increase Date. No other terms of the Credit Agreement were modified.

Item 9.01. Financial Statements and Exhibits.
