Item 1.01. Entry into a Material Definitive Agreement.

On September 26, 2014, we amended our existing financing facility (as amended “the Amended Financing Facility”) with UBS AG, London Branch (together with its affiliates “UBS”). The Amended Financing Facility includes amendments to the Company’s term financing facility (“Term Financing”) and the Company’s revolving financing facility (“Revolving Financing”) with UBS.

Pursuant to the Amended Financing Facility, we and/or our wholly owned subsidiary, CM SPV Ltd. (“CM SPV”), as applicable, entered into the following agreements: (i) an Amended and Restated Revolving Credit Note Agreement by and among CM Finance Inc (the “Company”), CM SPV, UBS, and State Street Bank and Trust Company (“State Street” as Revolving Credit Note Agent and Trustee); (ii) a Second Amended and Restated Indenture between CM SPV and State Street; (iii) a Second Amendment Agreement to 2002 ISDA Master Agreement between the Company and UBS AG (“UBS”); (iv) a Second Amendment Agreement to the Second Amended and Restated Indenture between CM SPV and State Street; (v) a Second Omnibus Amendment Agreement between CM SPV, CM Investment Partners LLC and State Street; (vi) an Amended Total Return Swap Confirmation Letter Agreement between UBS and the Company; and (vii) a Second Amended Total Return Swap Confirmation Letter Agreement between UBS and the Company.

Pursuant to the Amended Financing Facility, the maximum permissible portion of second lien loans in the collateral pool was increased to 60%, from 50%. The Term Financing was amended to, among other things (i) increase the facility amount from $76.5 million to $102.0 million, (ii) extend the final maturity by 18 months to December 2017, (iii) reduce the interest rate to LIBOR plus 2.75%, and (iv) obligate us to pay additional fees in the amount of $826,000 over the remaining term.
