FORM 8-K

CURRENT REPORT

Pursuant to Section 13 OR 15(d) of the Securities Exchange Act of 1934

Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On August 10, 2012, AmTrust Financial Services, Inc. (the “Company”) entered into a $200 million credit agreement (the “Credit Agreement”), among JPMorgan Chase Bank, N.A., as Administrative Agent, KeyBank National Association and SunTrust Bank, as Co-Syndication Agents, Associated Bank, National Association and Lloyds Securities Inc., as Co-Documentation Agents and the various lending institutions party thereto. The credit facility is a revolving credit facility with a letter of credit sublimit of $100 million and an expansion feature not to exceed $100 million. Proceeds of borrowings under the Credit Agreement may be used for working capital, acquisitions and general corporate purposes. In connection with entering into the Credit Agreement, the Company terminated its existing credit agreement, dated as of January 28, 2011, with JPMorgan Chase Bank, N.A., as Administrative Agent, The Bank of Nova Scotia, as Syndication Agent, SunTrust Bank, as Documentation Agent, and the various lending institutions party thereto. Letters of credit in the amount of $49.9 million, including $48.9 million issued and outstanding under the previous credit agreement, will be deemed issued under this Credit Agreement.

The Credit Agreement contains certain restrictive covenants customary for facilities of this type (subject to negotiated exceptions and baskets), including restrictions on indebtedness, liens, acquisitions and investments, restricted payments and dispositions. There are also financial covenants that require the Company to maintain a minimum consolidated net worth, a maximum consolidated leverage ratio, a minimum fixed charge coverage ratio, a minimum risk-based capital and a minimum statutory surplus. The Credit Agreement also provides for customary events of default, with grace periods where customary, including failure to pay principal when due, failure to pay interest or fees within three business days after becoming due, failure to comply with covenants, breaches of representations and warranties, default under certain other indebtedness, certain insolvency or receivership events affecting the Company and its subsidiaries, the occurrence of certain material judgments, or a change in control of the Company. Upon the occurrence and during the continuation of an event of default, the administrative agent, upon the request of the requisite percentage of the lenders, will terminate the obligations of the lenders to make loans and to issue letters of credit under the Credit Agreement, declare the Company’s obligations under the Credit Agreement to become immediately due and payable and/or exercise any and all remedies and other rights under the Credit Agreement. The Credit Agreement has a maturity date of August 10, 2016.

Borrowings under the Credit Agreement bear interest at either the Alternate Base Rate or the LIBO rate. ABR borrowings (which are borrowings bearing interest at a rate determined by reference to the Alternate Base Rate) under the Credit Agreement will bear interest at (x) the greatest of (a) the administrative agent’s prime rate, (b) the federal funds effective rate plus 0.5 percent or (c) the adjusted LIBO rate for a one-month interest period on such day plus 1 percent, plus (y) a margin that is adjusted on the basis of the Company’s consolidated leverage ratio. Eurodollar borrowings under the Credit Agreement will bear interest at the adjusted LIBO rate for the interest period in effect plus a margin that is adjusted on the basis of the Company’s consolidated leverage ratio. Fees payable by the Company under the Credit Agreement include a letter of credit participation fee (the margin applicable to Eurodollar borrowings), a letter of credit fronting fee with respect to each letter of credit (.125%) and a commitment fee on the available commitments of the lenders (a range of .20% to .30% based on the Company’s consolidated leverage ratio).

Certain of the lenders and their affiliates have provided, from time to time, and may continue to provide, investment banking, commercial banking, financial and other services to the Company, including letters of credit, depository and account processing services, for which the Company has paid and intends to pay customary fees.

The description of the Credit Agreement is qualified in its entirety by reference to the full text of the agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
