(8) Debt
The Company has a $400 million revolving credit facility, with the right, at the Company’s option and subject to certain conditions, to increase the borrowing capacity of the facility to $550 million. Any amounts outstanding under the revolving credit facility are due on July 20, 2014. At June 30, 2011, the Company had no amounts outstanding under the revolving credit facility, but had letters of credit outstanding of approximately $6.9 million, which reduce the Company’s borrowing availability under the revolving credit facility. Amounts borrowed under the revolving credit facility bear interest at LIBOR plus margins that depend on the Company’s leverage ratio. Indebtedness under the revolving credit facility is secured by substantially all of the Company’s assets, including the pledge of the stock of the Company’s principal domestic subsidiaries. The revolving credit facility contains customary events of default and requires that the Company satisfy various financial covenants. It also limits the Company’s ability to pay dividends or make other distributions, make acquisitions, make changes to the Company’s capital structure, create liens or incur additional indebtedness. At June 30, 2011, the Company was in compliance with all such covenants.
At June 30, 2011, the Company had outstanding $13.0 million in U.S. Government guaranteed long-term financing under Title XI of the Merchant Marine Act of 1936, which is administered by the Maritime Administration, for two 245-foot class liftboats. The debt bears interest at 6.45% per annum and is payable in equal semi-annual installments of $405,000 on June 3rd and December 3rd of each year through the maturity date of June 3, 2027. The Company’s obligations are secured by mortgages on the two liftboats. In accordance with the agreement, the Company is required to comply with certain covenants and restrictions, including the maintenance of minimum net worth, working capital and debt-to-equity requirements. At June 30, 2011, the Company was in compliance with all such covenants.
The Company also has outstanding $300 million of 6 7/8% unsecured senior notes due 2014. The indenture governing the 6 7/8% senior notes requires semi-annual interest payments on June 1st and December 1st of each year through the maturity date of June 1, 2014. The indenture contains certain covenants that, among other things, limit the Company from incurring additional debt, repurchasing capital stock, paying dividends or making other distributions, incurring liens, selling assets or entering into certain mergers or acquisitions. At June 30, 2011, the Company was in compliance with all such covenants.
In March 2010, the Company entered into an interest rate swap agreement for a notional amount of $150 million, whereby the Company is entitled to receive semi-annual interest payments at a fixed rate of 6 7/8% per annum and is obligated to make quarterly interest payments at a variable rate. The variable interest rate, which is adjusted every 90 days, is based on LIBOR plus a fixed margin (see note 17).
The Company has outstanding $400 million of 1.50% unsecured senior exchangeable notes due 2026. Effective January 1, 2009, the Company retrospectively adopted authoritative guidance related to debt with conversion and other options, which requires the proceeds from the issuance of the 1.50% unsecured senior exchangeable notes to be allocated between a liability (issued at a discount) and an equity component. The resulting debt discount is amortized over the period the exchangeable debt is expected to be outstanding as additional non-cash interest expense. The Company used an effective interest rate of 6.89% and will amortize this debt discount through December 12, 2011. The Company has recorded an unamortized discount of $9.6 million and $19.7 million at June 30, 2011 and December 31, 2010, respectively, related to these senior exchangeable notes. The senior exchangeable notes bear interest at a rate of 1.50% per annum and decrease to 1.25% per annum on December 15, 2011. Interest on the senior exchangeable notes is payable semi-annually on December 15th and June 15th of each year through the maturity date of December 15, 2026. The senior exchangeable notes do not contain any restrictive financial covenants.
Under certain circumstances, holders may exchange the notes for shares of the Company’s common stock. The initial exchange rate is 21.9414 shares of common stock per $1,000 principal amount of notes. This is equal to an initial exchange price of $45.58 per share. The exchange price represents a 35% premium over the closing share price at the date of issuance. The notes may be exchanged under the following circumstances:
  •   during any fiscal quarter (and only during such fiscal quarter), if the last reported sale price of the Company’s common stock is greater than or equal to 135% of the applicable exchange price of the notes for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter;
  •   prior to December 15, 2011, during the five business-day period after any ten consecutive trading-day period (the “measurement period”) in which the trading price of $1,000 principal amount of notes for each trading day in the measurement period was less than 95% of the product of the last reported sale price of the Company’s common stock and the exchange rate on such trading day;
  •   if the notes have been called for redemption;
  •   upon the occurrence of specified corporate transactions; or
  •   at any time beginning on September 15, 2026, and ending at the close of business on the second business day immediately preceding the maturity date of December 15, 2026.
Holders of the senior exchangeable notes may also require the Company to purchase all or a portion of their notes on December 15, 2011, December 15, 2016 and December 15, 2021 subject to certain administrative formalities. Conversely, on or after December 15, 2011 the Company may redeem at any time all or part of the notes. In each case, the purchase price payable will be equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest with all amounts payable in cash.
In connection with the senior exchangeable note transaction, the Company simultaneously entered into agreements with affiliates of the initial purchasers to purchase call options and sell warrants on its common stock. The Company may exercise the call options it purchased at any time to acquire approximately 8.8 million shares of its common stock at a strike price of $45.58 per share. The owners of the warrants may exercise the warrants to purchase from the Company approximately 8.8 million shares of the Company’s common stock at a price of $59.42 per share, subject to certain anti-dilution and other customary adjustments. The warrants may be settled, at the Company’s option, in cash, in common stock or in a combination of cash and common stock. Lehman Brothers OTC Derivatives, Inc. (LBOTC) is the counterparty to 50% of the Company’s call option and warrant transactions. In October 2008, LBOTC filed for bankruptcy protection. The Company continues to carefully monitor the developments affecting LBOTC. Although the Company may not retain the benefit of the call option due to LBOTC’s bankruptcy, the Company does not expect that there will be a material impact, if any, on the financial statements or results of operations. The call option and warrant transactions described above do not affect the terms of the outstanding exchangeable notes.
In April 2011, the Company issued $500 million of 6 3/8% unsecured senior notes due 2019. Costs associated with the issuance of these notes were approximately $9.6 million and were capitalized and will be amortized over the term of the 6 3/8% senior notes. The indenture governing the 6 3/8% senior notes requires semi-annual interest payments on May 1st and November 1st of each year through the maturity date of May 1, 2019. The indenture contains certain covenants that, among other things, limit the Company from incurring additional debt, repurchasing capital stock, paying dividends or making other distributions, incurring liens, selling assets or entering into certain mergers or acquisitions. At June 30, 2011, the Company was in compliance with all such covenants.
The Company has the ability to redeem its $400 million 1.50% unsecured senior exchangeable notes on or after December 15, 2011 for 100% of the principal amount plus any accrued and unpaid interest. The Company intends to use a portion of the net proceeds from the issuance of its 6 3/8% unsecured senior notes to redeem all of the outstanding senior exchangeable notes. The remaining net proceeds are available for general corporate purposes. In the interim, the Company used a portion of the proceeds to pay down all of its outstanding borrowings under its revolving credit facility. The remaining portions of the proceeds are included in cash and cash equivalents and short-term investments on the condensed consolidated balance sheet at June 30, 2011 (see note 5).
As the holders of the Company’s 1.50% senior exchangeable notes have the ability to require the Company to purchase all of the notes on December 15, 2011, the entire amount of these notes would have been deemed to be a current liability at December 31, 2010. However, in accordance with accounting guidance related to classification of short-term debt that is to be refinanced, the Company utilized the amount available to it under its revolving credit facility as of December 31, 2010 of approximately $216.0 million to classify this portion as long-term under the assumption that the revolving credit facility could be used to refinance that portion of the debt. Following completion of the 6 3/8% senior note offering in April 2011, the Company classified the $400 million senior exchangeable notes as current debt at June 30, 2011.
