In January 2013, we redeemed for cash all $143.8 million principal amount outstanding of our 4.75% convertible senior notes (the “4.75% Notes”) at a redemption price of 100% of the principal amount thereof plus accrued but unpaid interest to, but excluding, the redemption date. Upon redemption, the 4.75% Notes were no longer deemed outstanding, interest ceased to accrue thereon and all rights of the holders of the 4.75% Notes ceased to exist. The redemption of the 4.75% Notes was financed by borrowings under our revolving credit facility. As a result of the redemption, we expensed $0.9 million of unamortized deferred financing costs in the first quarter of 2013, which is reflected in interest expense in our condensed consolidated statements of operations.

In March 2012, we amended our senior secured credit facility (the “Credit Facility”) to decrease the borrowing capacity under our revolving credit facility by $200.0 million to $900.0 million. As a result of the decrease in borrowing capacity under our revolving credit facility, we expensed $1.3 million of unamortized deferred financing costs associated with our revolving credit facility in the first quarter of 2012, which is reflected in interest expense in our condensed consolidated statements of operations.

As of June 30, 2013, we had $246.0 million in outstanding borrowings and $156.7 million in outstanding letters of credit under the Credit Facility. At June 30, 2013, taking into account guarantees through letters of credit, we had undrawn and available capacity of $497.3 million under the Credit Facility.

In June 2009, we issued $355.0 million aggregate principal amount of 4.25% convertible senior notes due June 2014 (the “4.25% Notes”). The 4.25% notes are classified as long-term because we have the intent and ability to refinance the maturity of the notes with our existing Credit Facility or through conversion of the notes into common shares. The 4.25% Notes are convertible upon the occurrence of certain conditions into shares of our common stock at an initial conversion rate of 43.1951 shares of our common stock per $1,000 principal amount of the convertible notes, equivalent to an initial conversion price of approximately $23.15 per share of common stock. The conversion rate will be subject to adjustment following certain dilutive events and certain corporate transactions. The value of the shares into which the 4.25% Notes can be converted exceeds their principal amount by $76.2 million as of June 30, 2013. We may not redeem the 4.25% Notes prior to their maturity date.

In March 2012, the Partnership, amended its senior secured credit agreement (the “Partnership Credit Agreement”) to increase the borrowing capacity under its revolving credit facility by $200.0 million to $750.0 million. In March 2013, the Partnership Credit Agreement was amended to reduce the borrowing capacity under its revolving credit facility by $100.0 million to $650.0 million and extend the maturity date of the term loan and revolving credit facilities under the Partnership Credit Agreement to May 2018. The amendment decreased the applicable margins for the Partnership’s revolving credit and term loan facilities by 25 basis points and 50 basis points, respectively. Additionally, following the effectiveness of the amendment and upon the issuance of the Partnership’s 6% senior notes discussed below, the maximum allowed ratio of Total Debt (as defined in the Partnership Credit Agreement) to EBITDA (as defined in the Partnership Credit Agreement) increased to 5.25 to 1.0 (subject to a temporary increase to 5.5 to 1.0 for any quarter during which an acquisition meeting certain thresholds is completed and for the following two quarters after the acquisition closes) and the maximum allowed ratio of Senior Secured Debt (as defined in the Credit Agreement) to EBITDA is 4.0 to 1.0. As a result of the amendment to the Partnership Credit Agreement in March 2013, we expensed $0.7 million of unamortized deferred financing costs, which is reflected in interest expense in our condensed consolidated statements of operations. During the first quarter of 2013 and 2012, the Partnership incurred transaction costs of approximately $4.3 million and $0.5 million, respectively, related to the amendments to the Partnership Credit Agreement. These costs were included in intangible and other assets, net, and are being amortized over the terms of the facilities. As of June 30, 2013, the Partnership had undrawn and available capacity of $430.0 million under its revolving credit facility.

In March 2013, the Partnership issued $350.0 million aggregate principal amount of 6% senior notes due April 2021 (the “Partnership 6% Notes”). The Partnership used the net proceeds of $336.9 million, after original issuance discount and issuance costs, to repay borrowings outstanding under its revolving credit facility. The Partnership 6% Notes were issued at an original issuance discount of $5.5 million, which is being amortized using the effective interest method at an interest rate of 6.25% over their term. During the first quarter of 2013, the Partnership incurred transaction costs related to the issuance of the Partnership 6% Notes of approximately $7.6 million. These costs were included in intangible and other assets, net, and are being amortized to interest expense over the term of the Partnership 6% Notes. The Partnership 6% Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and unless so registered, may not be offered or sold in the U.S. except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The Partnership offered and issued the Partnership 6% Notes only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the U.S. pursuant to Regulation S. Pursuant to a registration rights agreement, the Partnership is required to register the Partnership 6% Notes no later than 365 days after March 27, 2013.

The Partnership 6% Notes are guaranteed on a senior unsecured basis by all of the Partnership’s existing subsidiaries (other than EXLP Finance Corp., which is a co-issuer of the Partnership 6% Notes) and certain of the Partnership’s future subsidiaries. The Partnership 6% Notes and the guarantees are the Partnership’s and the guarantors’ general unsecured senior obligations, respectively, rank equally in right of payment with all of the Partnership’s and the guarantors’ other senior obligations, and are effectively subordinated to all of the Partnership’s and the guarantors’ existing and future secured debt to the extent of the value of the collateral securing such indebtedness. In addition, the Partnership 6% Notes and guarantees are effectively subordinated to all existing and future indebtedness and other liabilities of any future non-guarantor subsidiaries.

Prior to April 1, 2017, the Partnership may redeem all or a part of the Partnership 6% Notes at a redemption price equal to the sum of (i) the principal amount thereof, plus (ii) a make-whole premium at the redemption date, plus accrued and unpaid interest, if any, to the redemption date. In addition, the Partnership may redeem up to 35% of the aggregate principal amount of the Partnership 6% Notes prior to April 1, 2016 with the net proceeds of one or more equity offerings at a redemption price of 106.000% of the principal amount of the Partnership 6% Notes, plus any accrued and unpaid interest to the date of redemption, if at least 65% of the aggregate principal amount of the Partnership 6% Notes issued under the indenture remains outstanding after such redemption and the redemption occurs within 180 days of the date of the closing of such equity offering. On or after April 1, 2017, the Partnership may redeem all or a part of the Partnership 6% Notes at redemption prices (expressed as percentages of principal amount) equal to 103.000% for the twelve-month period beginning on April 1, 2017, 101.500% for the twelve-month period beginning on April 1, 2018 and 100.000% for the twelve-month period beginning on April 1, 2019 and at any time thereafter, plus accrued and unpaid interest, if any, to the applicable redemption date on the Partnership 6% Notes.
