As discussed in Note 3 – Business Acquisitions, MWI Co.'s purchase of the assets of Micro was completed on October 31, 2011, using borrowing capacity that existed prior to the effectiveness of the Third Amendment. The Third Amendment allows for an aggregate revolving commitment of the Lenders under the Credit Agreement of $150,000 and a maturity date of November 1, 2016. Under the Third Amendment, the margin on variable interest rate borrowings ranges from 0.95% to 1.50%. The commitment fee under the Third Amendment ranges from 0.15% to 0.25% depending on the funded debt to EBITDA ratio.  The variable interest rate is equal to the Daily LIBOR Floating Rate or the LIBOR 1-month, 2-month, 3-month or 6-month fixed rate (at MWI Co.'s option) plus the margin.  The Credit Agreement contains financial covenants, including a fixed charge ratio and a funded debt to EBITDA ratio. We were in compliance with all of the covenants under the revolving credit facility as of June 30, 2013 and September 30, 2012. Sterling revolving credit facility— On March 15, 2013, Centaur Services Limited (“Centaur”) entered into a First Amendment (the “Amendment”) to the unsecured revolving line of credit facility (the “Sterling Revolving Credit Facility”) dated November 5, 2010 with Wells Fargo Bank, N.A. London Branch (“Wells Fargo”). The Amendment increases the maximum loan amount of the Sterling Revolving Credit Facility to £20,000, an increase of £7,500, and extends the term of the facility to November 1, 2016. Interest is based on LIBOR for the applicable interest period plus an applicable margin of .95% to 1.50% and the commitment fee ranges from .15% to .25%, depending on our funded debt to EBITDA ratio. The facility contains financial covenants requiring Centaur to maintain a minimum tangible net worth of £5,000. As of June 30, 2013 and September 30, 2012, Centaur was in compliance with this covenant.Also on March 15, 2013, Centaur also entered into an uncommitted overdraft facility (the “Overdraft Facility”) with Wells Fargo. The Overdraft Facility allows Centaur to borrow an additional £10,000 to fund short term normal trading cycle fluctuations. The Overdraft Facility will expire on November 1, 2016. Interest on the borrowing under the Overdraft Facility is the same as the terms under the Amendment. falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 505 -SubTopic 10 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=6928386&loc=d3e21475-112644 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 19, 20, 22 -Article 5 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 129 -Paragraph 2, 4 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
