Convertible Senior Notes

In April 2012, the Company issued Convertible Senior Notes due 2018 (the “Notes”) with an aggregate principal amount of $150 million in a public offering. The Notes bear interest at the rate of 3.375% per annum from the date of issuance, payable semi-annually on May 1 and November 1. The Notes are senior unsecured obligations of the Company ranking equally with its existing and future senior unsecured debt.

The Notes are convertible by their holders into cash, shares of the Company’s common stock or any combination thereof at the Company’s election, at an initial conversion rate of 85.4372 shares of the Company’s common stock per $1,000 in principal amount of Notes, which is equal to an initial conversion price of approximately $11.70 per share, only under the following circumstances: (A) before November 1, 2017 (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2012 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the indenture for the Notes) per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; and (3) upon the occurrence of specified corporate events as described in the indenture for the Notes; and (B) at any time on or after November 1, 2017 until the close of business on the second business day immediately preceding the maturity date. As of September 30, 2014, the Notes were not convertible based on the above criteria. If the Notes were converted as of September 30, 2014, the if-converted value would exceed the principal amount by approximately $21 million.

It is the Company’s intent to settle conversions through a net share settlement, which involves repayment of cash for the principal portion and delivery of shares of common stock for the excess of the conversion value over the principal portion. The Company used the net proceeds of approximately $145.1 million from the sale of the Notes to fund a portion of the purchase price of the acquisition of Walker Group Holdings LLC (“Walker”).

The Company accounts separately for the liability and equity components of the Notes in accordance with authoritative guidance for convertible debt instruments that may be settled in cash upon conversion. The guidance required the carrying amount of the liability component to be estimated by measuring the fair value of a similar liability that does not have an associated conversion feature. The Company determined that senior, unsecured corporate bonds traded on the market represent a similar liability to the Notes without the conversion option. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies in the same industry and with similar maturity, the Company estimated the implied interest rate of the Notes to be 7.0%, assuming no conversion option. Assumptions used in the estimate represent what market participants would use in pricing the liability component, including market interest rates, credit standing, and yield curves, all of which are defined as Level 2 observable inputs. The estimated implied interest rate was applied to the Notes, which resulted in a fair value of the liability component of $123.8 million upon issuance, calculated as the present value of implied future payments based on the $150.0 million aggregate principal amount. The $21.7 million difference between the cash proceeds before offering expenses of $145.5 million and the estimated fair value of the liability component was recorded in additional paid-in capital. The discount on the liability portion of the Notes is being amortized over the life of the Notes using the effective interest rate method.

The Company applies the treasury stock method in calculating the dilutive impact of the Notes. For the three and nine month periods ended September 30, 2014, the Notes had a dilutive impact.

The following table summarizes information about the equity and liability components of the Notes (dollars in thousands). The fair value of the Notes outstanding was measured based on quoted market prices.

Revolving Credit Agreement

In May 2012 the Company entered into an amendment and restatement of its then-existing senior secured revolving credit facility among the Company, certain of its subsidiaries (together with the Company, the “Borrowers”), Wells Fargo Capital Finance, LLC, as joint lead arranger, joint bookrunner and administrative agent (the “Revolver Agent”), RBS Citizens Business Capital, a division of RBS Citizens, N.A., as joint lead arranger, joint bookrunner and syndication agent, and the other lenders named therein, as amended (the “Amended and Restated Revolving Credit Agreement”). Also in May 2012, certain of the Company’s subsidiaries (the “Revolver Guarantors”) entered into a general continuing guarantee of the Borrowers’ obligations under the Amended and Restated Revolving Credit Agreement in favor of the lenders (the “Revolver Guarantee”).

The Amended and Restated Revolving Credit Agreement is guaranteed by the Revolver Guarantors and is secured by (i) first priority security interests (subject only to customary permitted liens and certain other permitted liens) in substantially all personal property of the Borrowers and the Revolver Guarantors, consisting of accounts receivable, inventory, cash, deposit and securities accounts and any cash or other assets in such accounts and, to the extent evidencing or otherwise related to such property, all general intangibles, licenses, intercompany debt, letter of credit rights, commercial tort claims, chattel paper, instruments, supporting obligations, documents and payment intangibles (collectively, the “Revolver Priority Collateral”), and (ii) second-priority liens on and security interests in (subject only to the liens securing the Term Loan Credit Agreement customary permitted liens and certain other permitted liens) (A) equity interests of each direct subsidiary held by the Borrower and each Revolving Guarantor (subject to customary limitations in the case of the equity of foreign subsidiaries), and (B) substantially all other tangible and intangible assets of the Borrowers and the Revolving Guarantors including equipment, general intangibles, intercompany notes, insurance policies, investment property, intellectual property and material owned real property (in each case, except to the extent constituting Revolver Priority Collateral) (collectively, the “Term Priority Collateral”). The respective priorities of the security interests securing the Amended and Restated Revolving Credit Agreement and the Term Loan Credit Agreement are governed by an Intercreditor Agreement between the Revolver Agent and the Term Agent (as defined below) (the “Intercreditor Agreement”). The Amended and Restated Revolving Credit Agreement has a scheduled maturity date of May 8, 2017.

Under the Amended and Restated Revolving Credit Agreement, the lenders agree to make available to the Company a $150 million revolving credit facility. The Company has the option to increase the total commitment under the facility to $200 million, subject to certain conditions, including (i) obtaining commitments from any one or more lenders, whether or not currently party to the Amended and Restated Revolving Credit Agreement, to provide such increased amounts and (ii) the available amount of increases to the facility being reduced by the amount of any incremental loans advanced under the Term Loan Credit Agreement in excess of $25 million. Availability under the Amended and Restated Revolving Credit Agreement will be based upon monthly (or more frequent under certain circumstances) borrowing base certifications of the Borrowers’ eligible inventory and eligible accounts receivable, and will be reduced by certain reserves in effect from time to time. Subject to availability, the Amended and Restated Revolving Credit Agreement provides for a letter of credit subfacility in an amount not in excess of $15 million, and allows for swingline loans in an amount not in excess of $10 million. Outstanding borrowings under the Amended and Restated Revolving Credit Agreement will bear interest at a rate, at the Borrowers’ election, equal to (i) LIBOR plus a margin ranging from 1.75% to 2.25% or (ii) a base rate plus a margin ranging from 0.75% to 1.25%, in each case depending upon the monthly average excess availability under the revolving loan facility. The Borrowers are required to pay a monthly unused line fee equal to 0.375% times the average daily unused availability along with other customary fees and expenses of the Revolver Agent and the lenders.

The Amended and Restated Revolving Credit Agreement contains customary covenants limiting the ability of the Company and certain of its affiliates to, among other things, pay cash dividends, incur debt or liens, redeem or repurchase stock, enter into transactions with affiliates, merge, dissolve, repay subordinated indebtedness, make investments and dispose of assets. In addition, the Company is required to maintain a minimum fixed charge coverage ratio of not less than 1.1 to 1.0 as of the end of any period of 12 fiscal months when excess availability under the Amended and Restated Revolving Credit Agreement is less than 12.5% of the total revolving commitment.

If availability under the Amended and Restated Revolving Credit Agreement is less than 15% of the total revolving commitment or if there exists an event of default, amounts in any of the Borrowers’ and the Revolver Guarantors’ deposit accounts (other than certain excluded accounts) will be transferred daily into a blocked account held by the Revolver Agent and applied to reduce the outstanding amounts under the facility.

Subject to the terms of the Intercreditor Agreement, if the covenants under the Amended and Restated Revolving Credit Agreement are breached, the lenders may, subject to various customary cure rights, require the immediate payment of all amounts outstanding and foreclose on collateral. Other customary events of default in the Amended and Restated Revolving Credit Agreement include, without limitation, failure to pay obligations when due, initiation of insolvency proceedings, defaults on certain other indebtedness, and the incurrence of certain judgments that are not stayed, satisfied, bonded or discharged within 30 days.

As of September 30, 2014, the Company had no outstanding borrowings under the Amended and Restated Revolving Credit Agreement and was in compliance with all covenants. The Company’s liquidity position, defined as cash on hand and available borrowing capacity on the revolving credit facility, amounted to $219.7 million as of September 30, 2014.

Term Loan Credit Agreement

In May 2012 the Company entered into a credit agreement among the Company, the several lenders from time to time party thereto, Morgan Stanley Senior Funding, Inc., as administrative agent, joint lead arranger and joint bookrunner (the “Term Agent”), and Wells Fargo Securities, LLC, as joint lead arranger and joint bookrunner, as amended (the “Term Loan Credit Agreement”), which provided for a senior secured term loan facility of $300 million to be advanced at closing and provides for a senior secured incremental term loan facility of up to $75 million, subject to certain conditions, including (i) obtaining commitments from any one or more lenders, whether or not currently party to the Term Loan Credit Agreement, to provide such increased amounts and (ii) the available amount of incremental loans being reduced by the amount of any increases in the maximum revolver amount under the Amended and Restated Revolving Credit Agreement (discussed above). Also in May 2012, certain of the Company’s subsidiaries (the “Term Guarantors”) entered into a general continuing guarantee of the Company’s obligations under the Term Loan Credit Agreement in favor of the Term Agent (the “Term Guarantee”).

In April 2013, the Company entered into Amendment No.1 to Credit Agreement (the “Amendment”), which became effective on May 9, 2013 and amended the Term Loan Credit Agreement. As of the Amendment date, there was approximately $297.0 million of term loans outstanding under the Term Loan Credit Agreement (the “Initial Loans”), of which the Company prepaid $20.0 million in connection with the Amendment. Under the Amendment, the lenders agreed to provide to the Company term loans in an aggregate principal amount of $277.0 million, which were exchanged for and used to refinance the Initial Loans (the “Tranche B-1 Loans”). The Tranche B-1 Loans mature on May 8, 2019, but provide for an accelerated maturity in the event the Company’s outstanding 3.375% Convertible Senior Notes due 2018 are not converted, redeemed, repurchased or refinanced in full on or before the date that is 91 days prior to the maturity date thereof. The Tranche B-1 Loans shall amortize in equal quarterly installments in aggregate amounts equal to 0.25% of the Tranche B-1 Loan amount, with the balance payable at maturity, and will bear interest at a rate, at the Company’s election, equal to (i) LIBOR (subject to a floor of 1.00%) plus a margin of 3.50% or (ii) a base rate plus a margin of 2.50%.

The Term Loan Credit Agreement is guaranteed by the Term Guarantors and is secured by (i) first-priority liens on and security interests in the Term Priority Collateral, and (ii) second-priority security interests in the Revolver Priority Collateral. In addition, the Amendment amended the Term Loan Credit Agreement, by among other things, removing the covenant that the Company be required to maintain a minimum interest coverage ratio. The Term Loan Credit Agreement requires the Company to maintain a maximum senior secured leverage ratio tested as of the last day of each fiscal quarter for the four consecutive fiscal quarters then ending of not more than (A) 4.5 to 1.0 through September 30, 2013, (B) 4.0 to 1.0 thereafter through September 30, 2015, and (C) 3.5 to 1.0 thereafter. The Term Loan Credit Agreement also contains conditions providing for either voluntary or mandatory prepayments. Conditions for mandatory prepayments include but are not limited to asset sales with proceeds in excess of $1 million and the amount of excess cash flows, as defined in the Term Loan Credit Agreement, as amended, to be calculated annually with the delivery of financial statements.

The Term Loan Credit Agreement contains customary covenants limiting the Company’s ability to, among other things, pay cash dividends, incur debt or liens, redeem or repurchase stock, enter into transactions with affiliates, merge, dissolve, pay off subordinated indebtedness, make investments and dispose of assets.

Subject to the terms of the Intercreditor Agreement, if the covenants under the Term Loan Credit Agreement are breached, the lenders may, subject to various customary cure rights, require the immediate payment of all amounts outstanding and foreclose on collateral. Other customary events of default in the Term Loan Credit Agreement include, without limitation, failure to pay obligations when due, initiation of insolvency proceedings, defaults on certain other indebtedness, and the incurrence of certain judgments that are not stayed, satisfied, bonded or discharged within 60 days.

As of September 30, 2014, the Company’s senior secured leverage ratio was 0.8:1.0, and the Company was in compliance with all covenants under the Term Loan Credit Agreement.

For the nine months ended September 30, 2014 and 2013, under the Term Loan Credit Agreement the Company paid interest of $7.9 million and $12.0 million, respectively, and principal of $42.1 million during each nine month periods. As of September 30, 2014, the Company had $192.8 million outstanding under the Term Loan Credit Agreement, all of which was classified as long-term debt on the Company’s Condensed Consolidated Balance Sheet as a result of the Company’s election to apply a voluntary principal payment in September 2014 in a manner that fulfilled the Company’s obligation to pay the future mandatory quarterly amortization installments as required by the Term Loan Credit Agreement. In connection with the closing of the Term Loan Credit Agreement in May 2012 and the Amendment in April 2013, the Company paid a total of $8.5 million in original issuance discount fees which are being amortized over the life of the facility using the effective interest rate method.

For each of the nine months ended September 30, 2014 and 2013, the Company charged $0.7 million of amortization for original issuance discount fees as Interest Expense in the Condensed Consolidated Statements of Operations. In addition, for each of the nine month periods ended September 30, 2014 and 2013, the Company charged $0.9 million of accelerated amortization in connection with its voluntary principal payments as Other, net in the Condensed Consolidated Statements of Operations.

Other Debt Facilities

In November 2012, the Company entered into a loan agreement with GE Government Finance, Inc. as lender and the County of Trigg, Kentucky as issuer for a $2.5 million Industrial Revenue Bond. The funds received were used to purchase the equipment needed for the expansion of the Company’s Cadiz, Kentucky facility. The loan bears interest at a rate of 4.25% and matures in March 2018. As of September 30, 2014, the Company had $1.8 million outstanding, of which $0.5 million was classified as current on the Condensed Consolidated Balance Sheet.
