On March 30, 2011, the Company entered into a new credit agreement for up to $330.0 million of credit with a group of commercial banks (the “Original Credit Agreement”). On November 29, 2011, the Company amended the Original Credit Agreement to increase the amount available by $100.0 million to $430.0 million (the “Credit Agreement”). The Credit Agreement consists of a $380.0 million line of credit, which includes the ability to borrow up to $50.0 million in specified foreign currencies or U.S. dollars (the “Domestic and Multi-currency Line”) and a $50.0 million term loan facility (the “2015 Variable Rate Notes”). The Domestic and Multi-currency Line will decrease by $100.0 million to $280.0 million on the earlier of May 29, 2013 or the second business day following the closing of an initial public offering of common stock of Enova International, Inc., a wholly-owned subsidiary of the Company (“Enova”), that results in Enova no longer being considered a majority-owned subsidiary of the Company. The Domestic and Multi-currency Line matures on March 31, 2015. Beginning March 31, 2012, the 2015 Variable Rate Notes became payable in equal quarterly principal installments of $2.1 million with any outstanding principal remaining due at maturity on March 31, 2015. Interest on the Domestic and Multi-currency Line is charged, at the Company's option, at either the London Interbank Offered Rate (“LIBOR”) plus a margin varying from 2.00% to 3.25% or at the agent's base rate plus a margin varying from 0.50% to 1.75%. Interest on the 2015 Variable Rate Notes is charged, at the Company's option, at either LIBOR plus a margin of 3.50% or at the agent's base rate plus a margin of 2.00%. The margin for the Domestic and Multi-currency Line is dependent on the Company's cash flow leverage ratios as defined in the Credit Agreement. The Company also pays a fee on the unused portion of the Domestic and Multi-currency Line ranging from 0.25% to 0.50% (0.38% at December 31, 2012) based on the Company's cash flow leverage ratios. The weighted average interest rate (including margin) on the Domestic and Multi-currency Line was 3.06% and 3.08% at December 31, 2012 and 2011, respectively. The weighted average interest rate (including margin) on the 2015 Variable Rate Notes was 3.75% and 3.81% at December 31, 2012 and 2011, respectively.

In conjunction with the entry into the Original Credit Agreement, the Company repaid all outstanding revolving credit loans under its $300.0 million domestic line of credit due 2012 (the “USD Line of Credit”) and its variable rate senior unsecured note due 2012 with proceeds of the Original Credit Agreement.

As of December 31, 2012, borrowings under the Company's Domestic and Multi-currency Line consisted of three pricing tranches with maturity dates ranging from two to 31 days, and as of December 31, 2011, borrowings under the Company's Domestic and Multi-currency Line consisted of multiple pricing tranches with maturity dates ranging from three to 31 days. However, the Company routinely refinances borrowings pursuant to the terms of its Domestic and Multi-currency Line. Therefore, these borrowings are reported as part of the applicable line of credit and as long-term debt.

In connection with the Domestic and Multi-currency Line and the 2015 Variable Rate Notes, the Company incurred approximately $2.6 million for issuance costs in 2011, which primarily consisted of underwriting fees, legal and other professional expenses. These costs are being amortized over a period of three years and are included in “Other assets” in the Company's consolidated balance sheets.

On August 28, 2012, the Company issued and sold a total of $52.0 million in long-term notes in two series, including $47.0 million aggregate principal amount of its 6.00% Series A Senior Notes due August 28, 2019 (the “Series A Notes”) and $5.0 million aggregate principal amount of its 6.58% Series B Senior Notes due August 28, 2022 (the “Series B Notes,” and together with the Series A Notes, the “Notes”). The Notes were sold in a private placement pursuant to a Note Purchase Agreement dated August 28, 2012 by and among the Company and certain purchasers listed therein. The Notes are senior unsecured obligations of the Company. The Series A Notes are payable in five annual installments of $9.4 million beginning August 28, 2015, and the Series B Notes are payable in seven annual installments of approximately $0.7 million beginning August 28, 2016. In addition, the Company may, at its option, prepay all or a minimum portion of $1.0 million of the Notes at a price equal to the principal amount thereof plus a make-whole premium and accrued interest. The Notes are guaranteed by all of the Company's U.S. subsidiaries. The Company used a portion of the net proceeds of the offering to repay existing indebtedness, including outstanding balances under the Domestic and Multi-Currency Line, and used the remaining portion for general corporate purposes.

On May 19, 2009, the Company completed the offering of $115.0 million aggregate principal amount of 5.25% Convertible Senior Notes due May 15, 2029 (the “2009 Convertible Notes”). The 2009 Convertible Notes are senior unsecured obligations of the Company. The 2009 Convertible Notes bear interest at a rate of 5.25% per year, payable semi-annually on May 15 and November 15 of each year. The 2009 Convertible Notes will be convertible, in certain circumstances, at an initial conversion rate of 39.2157 shares per $1,000 aggregate principal amount of 2009 Convertible Notes (which is equivalent to a conversion price of approximately $25.50 per share), subject to adjustment upon the occurrence of certain events, into either, at the Company's election: (i) shares of common stock or (ii) cash up to their principal amount and shares of its common stock with respect to the remainder, if any, of the conversion value in excess of the principal amount. The Company may not redeem the 2009 Convertible Notes prior to May 14, 2014. The Company may, at its option, redeem some or all of the 2009 Convertible Notes on or after May 15, 2014 solely for cash. Holders of the 2009 Convertible Notes will have the right to require the Company to repurchase some or all of the outstanding 2009 Convertible Notes, solely for cash, on May 15, 2014, May 15, 2019 and May 15, 2024 at a price equal to 100% of the principal amount plus any accrued and unpaid interest.

As of December 31, 2012 and 2011, the carrying amount of the 2009 Convertible Notes was $110.2 million and $107.1 million, respectively, and the unamortized discount was $4.8 million and $7.9 million, respectively. The discount is being amortized to interest expense over a period of five years, through the first redemption date of May 19, 2014. The total interest expense recognized was $9.2 million, $8.9 million and $8.7 million for the years ended December 31, 2012, 2011 and 2010, respectively, of which $3.2 million, $2.9 million and $2.7 million represented the non-cash amortization of the discount, and $6.0 million, $6.0 million and $6.0 million represented the contractual interest expense for the years ended December 31, 2012, 2011 and 2010, respectively. The 2009 Convertible Notes have an effective interest rate of 8.46% at both December 31, 2012 and 2011, respectively. As of December 31, 2012, the if-converted value of the 2009 Convertible Notes exceeds the principal amount by approximately $59.7 million.

In connection with the issuance of the 2009 Convertible Notes, the Company incurred approximately $3.9 million for issuance costs, which primarily consisted of underwriting fees, legal and other professional expenses. The unamortized balance of these costs as of December 31, 2012 is included in “Other assets” in the Company's consolidated balance sheets. These costs are being amortized to interest expense over five years.

As of both December 31, 2012 and 2011, the carrying amount of the equity component recorded as additional paid-in capital was $9.4 million, net of deferred taxes and equity issuance costs.

On March 30, 2011, in conjunction with the establishment of the Original Credit Agreement, the Company entered into a separate credit agreement for the issuance of $20.0 million in letters of credit (the “Letter of Credit Facility”). The Company had standby letters of credit of $17.7 million issued under the Letter of Credit Facility as of December 31, 2012.

Each of the Company's credit agreements and senior unsecured notes require the Company to maintain certain financial ratios. As of December 31, 2012, the Company was in compliance with all covenants or other requirements set forth in its debt agreements.

As of December 31, 2012, required principal payments under the terms of the long-term debt, including the Company's line of credit, for each of the five years after December 31, 2012 are as follows (dollars in thousands):
