Long-Term Debt

ABL Facility

On June 1, 2015, the Company and Command, as co-borrowers, entered into a Revolving Credit and Security Agreement (the “Credit Agreement”) with PNC Bank. The Credit Agreement provides for a senior secured revolving credit facility in an initial aggregate principal amount of up to $200 million (the “ABL Facility”). The initial aggregate principal amount under the ABL Facility may be increased from time to time by an additional $100 million to a maximum aggregate principal amount of $300 million; provided, however, that only four increases are permitted during the life of the loan and, for each increase, certain requirements are satisfied. The Company’s obligations under the ABL Facility are secured, on a first lien priority basis, by certain working capital assets.

Interest is payable at a rate per annum equal to, at the option of the Company, any of the following, plus, in each case, an applicable margin: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate, plus 0.50%, (2) the base commercial lending rate of PNC Bank, National Association and (3) a daily LIBOR rate, plus 1.00%; or (b) a LIBOR rate determined by reference to the costs of funds for deposits in the relevant currency for the interest period relevant to such borrowing adjusted for certain additional costs. The applicable margin will be 0.25% to 0.75% for borrowings at the base rate and 1.25% to 1.75% for borrowings at the LIBOR rate, in each case, based on the excess availability under the ABL Facility.

The Company will also be required to pay a commitment fee in respect to the unutilized commitments under the ABL Facility of between 0.25% and 0.375% based on the excess availability for the prior calendar quarter under the ABL Facility. At March 31, 2016, the Company's commitment fee was calculated at a rate of 0.375%.

The terms of the ABL Facility include various covenants, including a covenant that requires the Company to maintain a consolidated fixed charge coverage ratio at any time (a) a specified default occurs or (b) if excess availability falls below certain specified levels. As of March 31, 2016, neither of the events that would require the Company to maintain the fixed charge coverage ratio occurred, and the Company is in compliance with all covenants related to the ABL.

The Company drew $6.0 million on the ABL Facility during the first quarter of 2016, all of which was repaid as of March 31, 2016. No amounts were outstanding on the ABL Facility as of March 31, 2016.

The issuance of letters of credit under the ABL Facility reduces available borrowings. At March 31, 2016, there were $0.7 million of letters of credit outstanding. The total draw allowed on the ABL Facility at March 31, 2016, as determined by the working capital assets pledged as collateral, was $169.1 million. After adjusting for the letters of credit, the Company's remaining availability under the ABL Facility at March 31, 2016 was $168.4 million.

The Company incurred issuance costs of $3.1 million in 2015 related to the ABL Facility. These issuance costs are being amortized to interest expense using straight-line amortization over the 5 year life of the ABL Facility. During the first quarter of 2016, the Company recorded $0.2 million of interest expense related to ABL Facility issuance costs. As there is no outstanding draw on the ABL Facility at March 31, 2016, the unamortized issuance costs are presented as a deferred asset on the balance sheet.

Convertible Senior Notes

On May 5, 2015, the Company issued $230 million aggregate principal amount of 2.50% convertible senior notes due 2020 (the “Notes”) in a registered public offering. The proceeds from the Company's sale of the Notes, net of underwriting discounts and commissions, were $223.1 million. The Company used all of the net proceeds from the Notes offering (together with proceeds from the sale of common stock and borrowings under the ABL Facility) to finance the acquisition of Command.

The Notes bear interest at a rate of 2.50% per year payable semiannually in arrears in cash on May 1 and November 1 of each year, beginning on November 1, 2015. The Notes will mature on May 1, 2020, unless earlier converted or repurchased in accordance with the terms discussed below. The Notes are the Company's senior unsecured obligations and rank senior in right of payment to any of the Company's indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of the Company's unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company's subsidiaries.

The Notes will be convertible, under certain circumstances and during certain periods, into cash, shares of the Company's common stock, or a combination of cash and shares of common stock at the Company's election, at an initial conversion rate of 25.5428 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $39.15 per share of common stock.

Holders may convert their Notes at their option at any time prior to the close of business on the business day immediately preceding January 1, 2020 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2015 (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 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; (3) if the Company calls the Notes for redemption, at any time prior to the close of business on the business day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events.

If the Company undergoes a fundamental change, subject to certain conditions, holders of the Notes may require the Company to purchase for cash all or a part of their Notes at a repurchase price equal to 100% of the principal amount of Notes to be repurchased, plus accrued and unpaid interest. In addition, following certain corporate events that occur prior to maturity, the Company may increase the conversion rate for a holder who elects to convert its Notes in connection with such a corporate event in certain circumstances. In such event, the conversion rate could increase to a maximum of 34.4827 shares of common stock per $1,000 principal amount of Notes.

On or after January 1, 2020 until the close of business on the business day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver cash, shares of the Company's common stock, or a combination of cash and shares of the Company's common stock, at the Company's election.

The Company's intent and policy will be to settle the $230 million principal amount of Notes in cash, and any excess conversion premium in shares of common stock. As such, the principal amount of the Notes will not be included in the calculation of diluted earnings per common share, but any conversion premium that exists will be included in the calculation of diluted earnings per common share using the treasury stock method. As of March 31, 2016, none of the conditions allowing holders of the Notes to convert have been met and no conversion spread exists. As such, the notes did not have a dilutive impact on diluted earnings per common share for the three months ended March 31, 2016.

The accounting guidance in ASC 470-20, Debt with Conversion and Other Options, requires that the principal amount of the Notes be separated into liability and equity components at issuance. The value assigned to the liability component is the estimated fair value, as of the issuance date, of a similar debt instrument without the conversion feature. The difference between the principal amount of the Notes and the estimated fair value of the liability component, representing the value of the conversion premium assigned to the equity component, is recorded as a debt discount on the issuance date. The fair value of the liability component of the Notes was determined using a discounted cash flow analysis, in which the projected interest and principal payments were discounted back to the issuance date of the Notes at an estimated market yield for a similar debt instrument without the conversion feature. The Company estimated the straight debt yield using a combination of inputs observable in the marketplace, including the credit spread indicated by the terms of the Company's ABL Facility, LIBOR rates, and U.S. Treasury bonds. This represents a Level 2 valuation technique. The Company estimated the straight debt borrowing rates at issuance to be 5.75% for similar debt to the Notes without the conversion feature, which resulted in a fair value of the liability component of $198.5 million and a fair value of the equity component of $31.5 million. The fair value of the equity component was recorded as a debt discount, with the offset recorded as a credit to additional paid-in capital within stockholders' equity. The $31.5 million debt discount and Note issuance costs discussed below are being amortized to interest expense under the effective interest method over the 5 year life of the Notes, using an effective interest rate of 6.33%.

The Company allocated the total issuance costs related to the Notes to the liability and equity components based on their relative fair values. Issuance costs attributable to the liability component were recorded on the consolidated balance sheets as a contra-liability that reduces the carrying amount of the convertible note liability. This amount is being amortized to interest expense over the term of the Notes using the effective interest method and an effective interest rate of 6.33%. Issuance costs attributable to the equity component were recorded as a charge to additional paid-in capital within stockholders' equity.

As of March 31, 2016, the carrying amount of the Notes on the balance sheet is $198.3 million, calculated as follows:



	March 31, 2016
Convertible senior notes, principal amount	$	230,000,000
Unamortized debt discount	(26,428,209		)
Unamortized debt issuance costs	(5,226,948		)
Convertible senior notes, net	$	198,344,843

The Notes are carried on the balance sheet at their principal amount, net of the unamortized debt discount and unamortized debt issuance costs, and are not marked to market each period. The approximate fair value of the Notes as of March 31, 2016 was $232.6 million. The fair value of the Notes was estimated based on the trading price of the Notes at March 31, 2016. As trading volume is low, these are quoted prices for identical instruments in markets that are not active, and thus are Level 2 in the fair value hierarchy.

The Company has recognized interest expense related to the Notes of $3.1 million for the three months ended March 31, 2016, consisting of $1.4 million of contractual coupon interest, $1.4 million of debt discount amortization and $0.3 million of debt issuance cost amortization.

The undiscounted interest and principal payments due in relation to the Notes from March 31, 2016 to the maturity of the Notes on May 1, 2020 are as follows:



	Total		2016	2017	2018	2019	2020
Senior convertible notes, including interest	$	255,875,000	5,750,000	5,750,000	5,750,000	5,750,000	$	232,875,000
