Debt

On May 13, 2010, the Company completed a private placement of €75.0 million aggregate principal amount of senior unsecured notes to accredited institutional investors. The €75.0 million of senior notes consists of €30.0 million aggregate principal amount of 3.71% Series 2010-A Senior Notes, due May 13, 2017 and €45.0 million aggregate principal amount of 4.24% Series 2010-A Senior Notes, due May 13, 2020, with interest payable on the notes semiannually. This private placement was exempt from the registration requirements of the Securities Act of 1933. The notes have been fully and unconditionally guaranteed on an unsecured basis by the Company’s domestic subsidiaries.

During fiscal 2006 and 2007, the Company completed two private placement note issuances totaling $350 million in ten-year fixed rate notes with varying maturity dates to institutional investors at interest rates varying from 5.30% to 5.33%. The notes must be repaid equally over seven years, with interest payable on the notes due semiannually on various dates throughout the year. The private placements were exempt from the registration requirements of the Securities Act of 1933. The notes were not registered for resale and may not be resold absent such registration or an applicable exemption from the registration requirements of the Securities Act of 1933 and applicable state securities laws. The notes have certain prepayment penalties for repaying them prior to the maturity date. Under the debt agreement, the Company made scheduled principal payments of $42.5 million in fiscal years 2016 and 2015, respectively. The final principal payment for the 2006 series of notes was made during fiscal 2016, while the final principal payment for the 2007 series of notes is due in fiscal 2017. The Company intends to utilize our revolving credit facility to fund private placement principal payments due during the fiscal year ended July 31, 2017, and therefore the maturities are included in "Long-term obligations, less current maturities" on the Consolidated Balance Sheets as of July 31, 2016.

On September 25, 2015, the Company and certain of its subsidiaries entered into an unsecured $300,000 multi-currency revolving loan agreement with a group of six banks. Under the new revolving loan agreement, which has a final maturity date of September 25, 2020, the Company has the option to select either a base interest rate (based upon the higher of the federal funds rate plus one-half of 1%, the prime rate of Bank of America plus a margin based on the Company’s consolidated leverage ratio, or the one-month LIBOR rate plus 1%) or a Eurocurrency interest rate (at the LIBOR rate plus a margin based on the Company’s consolidated leverage ratio). At the Company’s option, and subject to certain conditions, the available amount under the revolving loan agreement may be increased from $300,000 up to $450,000. During fiscal 2016, the Company drew $10,000 from its revolving loan agreement in order to fund general corporate needs and the maximum amount outstanding throughout the year was $135,000. As of July 31, 2016, the outstanding balance on the credit facility was $112,000 and the Company had outstanding letters of credit under the revolving loan agreement of $4,261. There was $183,739 available for future borrowing under the credit facility, which can be increased to $333,739 at the Company's option, subject to certain conditions. The revolving loan agreement has a final maturity date of September 25, 2020. As such, the borrowing is included in "Long-term obligations, less current maturities" on the Consolidated Balance Sheets.

The Company has two multi-currency lines of credit in China with capacity of $10,000 each. These lines of credit support USD-denominated or CNY-denominated borrowing to fund working capital and operations for the Company's Chinese entities and are due on demand. The borrowings under these facilities may be made for a period up to one year from the date of borrowing with interest on the USD-denominated borrowings incurred equal to U.S. dollar LIBOR on the date of borrowing plus a margin based upon duration and on the CNY-denominated borrowings incurred equal to the local China rate based upon duration. There is no ultimate maturity on the facilities and they are subject to periodic review and repricing. The Company is not required to comply with any financial covenants as part of the agreements. The maximum amount outstanding on these facilities was $10,411 and the Company repaid $5,483 during fiscal 2016. As of July 31, 2016, the aggregate outstanding balance on these lines of credit in China was $4,928 and there was $15,072 available for future borrowings. Due to the short-term nature of these credit facilities, the borrowings are classified as "Notes payable" within current liabilities on the Consolidated Balance Sheets.

The Company’s debt agreements require it to maintain certain financial covenants, including a ratio of debt to the trailing twelve months EBITDA, as defined in the debt agreements, of not more than a 3.5 to 1.0 ratio (leverage ratio) and the trailing twelve months EBITDA to interest expense of not less than a 3.0 to 1.0 ratio (interest expense coverage). As of July 31, 2016, the Company was in compliance with these financial covenants, with the ratio of debt to EBITDA, as defined by the agreements, equal to 1.4 to 1.0 and the interest expense coverage ratio equal to 19.9 to 1.0.

The estimated fair value of the Company’s long-term obligations was $218,977 and $252,254 at July 31, 2016 and July 31, 2015, respectively, as compared to the carrying value of $211,982 and $243,288 at July 31, 2016 and July 31, 2015, respectively. The fair value of the long-term obligations, which were determined using the market approach based upon the interest rates available to the Company for borrowings with similar terms and maturities, were determined to be Level 2 under the fair value hierarchy.
