The offering price of the Unregistered 7 7/8% Notes was 98.545% of par after adjustment for original issue discount. Provisions of the Unregistered 7 7/8% Notes include, without limitation, restrictions on indebtedness, asset sales, and dividends and other restricted payments. Until February 1, 2014, the Company may redeem up to 35% of the outstanding Unregistered 7 7/8% Notes at a redemption price of 107.875% with the proceeds of equity offerings, subject to certain restrictions. On or after February 1, 2015, the Unregistered 7 7/8% Notes are redeemable at the option of the Company, in whole or in part, at a redemption price of 103.938%, reducing to 101.969% and 100% on February 1, 2016 and February 1, 2017, respectively and are due February 1, 2019.

The Unregistered 7 7/8% Notes are guaranteed by certain existing and future U.S. subsidiaries and are not subject to any sinking fund requirements. On June 2, 2011 the Company exchanged $150,000,000 of its outstanding Unregistered 7 7/8% Notes due 2019 for a like principal amount of its 7 7/8% Notes due 2019, registered under the Securities Act of 1933, as amended (7 7/8% Notes). All of the Unregistered 7 7/8% Senior Subordinated Notes due 2019 were exchanged in the transaction. The 7 7/8% Notes contain identical terms and provisions as the Unregistered 7 7/8% Notes. The Company's Notes payable to banks consist primarily of draws against unsecured non-U.S. lines of credit. The Company's other senior debt consists primarily of capital lease obligations. Unsecured and uncommitted lines of credit are available to meet short-term working capital needs for certain of our subsidiaries operating outside of the U.S. The lines of credit are available on an offering basis, meaning that transactions under the line of credit will be on such terms and conditions, including interest rate, maturity, representations, covenants and events of default, as mutually agreed between our subsidiaries and the local bank at the time of each specific transaction. As of December 31, 2012, unsecured credit lines totaled approximately $8,126,000, of which $0 was drawn. In addition to the above facilities, one of our foreign subsidiaries has a credit line secured by a parent company guarantee. This credit line provides availability of up to $963,000, of which $0 was drawn as of December 31, 2012. Refer to the Company's consolidated financial statements included in its annual report on Form 10-K for the year ended March 31, 2012 for further information on its debt arrangements.
