Credit Agreements

In May 2011, the Company entered into an amendment to, and restatement of, its credit agreement, referred to as the Amended Credit Agreement. The Amended Credit Agreement provided a maximum commitment on the Company's revolving credit line of $250.0 million and a maturity date of May 2016. Borrowings under the revolving credit line of the Amended Credit Agreement accrued interest, at the Company's option, at either (a) the greater of (i) the prime rate, (ii) the federal funds rate plus 0.50% and (iii) adjusted LIBOR plus 1.00% or (b) LIBOR, plus margins ranging from 0.80% to 1.65%. There was also a facility fee ranging from 0.20% to 0.35%. The Amended Credit Agreement was repaid in full in October 2015.

On October 27, 2015, the Company entered into a new revolving credit agreement, referred to as the 2015 Credit Agreement, and terminated the Amended Credit Agreement. The 2015 Credit Agreement provides a maximum commitment on the Company's revolving credit line of $500 million and a maturity date of October 2020. Borrowings under the revolving credit line of the 2015 Credit Agreement accrue interest, at the Company's option, at either (a) the greater of (i) the prime rate, (ii) the federal funds rate plus 0.50% and (iii) adjusted LIBOR plus 1.00%, plus margins ranging from 0.00% to 0.30% or (b) LIBOR, plus margins ranging from 0.90% to 1.30%. There is also a facility fee ranging from 0.10% to 0.20%.

Borrowings under the 2015 Credit Agreement are secured by guarantees from certain material subsidiaries, as defined in the 2015 Credit Agreement. The 2015 Credit Agreement also requires the Company to maintain certain financial ratios related to maximum leverage and minimum interest coverage (as defined in the 2015 Credit Agreement). Specifically, the Company's leverage ratio cannot exceed 3.5 and the Company's interest coverage ratio cannot be less than 2.5. In addition to the financial ratios, the 2015 Credit Agreement contains negative covenants, including among others, restrictions on liens, indebtedness of the Company and its subsidiaries, asset sales, dividends and transactions with affiliates. Failure to comply with any of these restrictions or covenants may result in an event of default on the 2015 Credit Agreement, which could permit acceleration of the debt and require the Company to prepay the debt before its scheduled due date.

As of December 31, 2016, the Company was in compliance with the covenants of the 2015 Credit Agreement. The Company's leverage ratio (as defined in the 2015 Credit Agreement) was 1.49 and interest coverage ratio (as defined in the 2015 Credit Agreement) was 15.5.

The following is a summary of the maximum commitments and the net amounts available to the Company under the 2015 Credit Agreement and other lines of credit with various financial institutions located primarily in Germany and Switzerland that are unsecured and typically due upon demand with interest payable monthly, at December 31, 2016 (in millions):

Note Purchase Agreement

In January 2012, the Company entered into a note purchase agreement, referred to as the Note Purchase Agreement, with a group of accredited institutional investors. Pursuant to the Note Purchase Agreement, the Company issued and sold $240.0 million of senior notes, referred to as the Senior Notes, which consist of the following:


	•	$20 million 3.16% Series 2012A Senior Notes, Tranche A, due January 18, 2017;
	•	$15 million 3.74% Series 2012A Senior Notes, Tranche B, due January 18, 2019;
	•	$105 million 4.31% Series 2012A Senior Notes, Tranche C, due January 18, 2022; and
	•	$100 million 4.46% Series 2012A Senior Notes, Tranche D, due January 18, 2024.

Under the terms of the Note Purchase Agreement, the Company may issue and sell additional senior notes up to an aggregate principal amount of $600 million, subject to certain conditions. Interest on the Senior Notes is payable semi-annually on January 18 and July 18 of each year. The Senior Notes are unsecured obligations of the Company and are fully and unconditionally guaranteed by certain of the Company's direct and indirect subsidiaries. The Senior Notes rank pari passu in right of repayment with the Company's other senior unsecured indebtedness. The Company may prepay some or all of the Senior Notes at any time in an amount not less than 10% of the original aggregate principal amount of the Senior Notes to be prepaid, at a price equal to the sum of (a) 100% of the principal amount thereof, plus accrued and unpaid interest, and (b) the applicable make-whole amount, upon not less than 30 and no more than 60 days written notice to the holders of the Senior Notes. In the event of a change in control of the Company, as defined in the Note Purchase Agreement, the Company may be required to prepay the Notes at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest.

The Note Purchase Agreement contains affirmative covenants, including, without limitation, maintenance of corporate existence, compliance with laws, maintenance of insurance and properties, payment of taxes, addition of subsidiary guarantors and furnishing notices and other information. The Note Purchase Agreement also contains certain restrictive covenants that restrict the Company's ability to, among other things, incur liens, transfer or sell assets, engage in certain mergers and consolidations and enter into transactions with affiliates. The Note Purchase Agreement also includes customary representations and warranties and events of default. In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding Senior Notes will become due and payable immediately without further action or notice. In the case of payment events of defaults, any holder of Senior Notes affected thereby may declare all Senior Notes held by it due and payable immediately. In the case of any other event of default, a majority of the holders of the Senior Notes may declare all the Senior Notes to be due and payable immediately. Pursuant to the Note Purchase Agreement, so long as any Senior Notes are outstanding the Company will not permit (i) its leverage ratio, as determined pursuant to the Note Purchase Agreement, as of the end of any fiscal quarter to exceed 3.50 to 1.00, (ii) its interest coverage ratio as determined pursuant to the Note Purchase Agreement as of the end of any fiscal quarter for any period of four consecutive fiscal quarters to be less than 2.50 to 1 or (iii) priority debt at any time to exceed 25% of consolidated net worth, as determined pursuant to the Note Purchase Agreement.

As of December 31, 2016, the Company was in compliance with the covenants of the Note Purchase Agreement. The Company's leverage ratio (as defined in the Note Purchase Agreement) was 1.49 and interest coverage ratio (as defined in the Note Purchase Agreement) was 15.5.

Annual maturities of debt outstanding, less deferred financing cost amortization, at December 31, 2016 are as follows (in millions):

2017	$	20.1
2018		0.1
2019		15.0
2020		171.0
2021		—

Interest expense for the years ended December 31, 2016, 2015 and 2014, was $13.2 million, $13.0 million and $13.3 million, respectively.

In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amends the existing guidance to require that debt issuance costs be presented in the consolidated balance sheet as a reduction from the carrying amount of the related debt liability instead of as an other asset. The Company adopted ASU 2015-03 on a retrospective basis for the year ended December 31, 2016. As of December 31, 2016 and 2015, there were $0.8 million and $0.9 million, respectively, in debt issuance costs recorded as a reduction in the carrying value of the related debt liability under the Note Purchase Agreement. The $0.8 million in debt issuance costs as of December 31, 2016 will be amortized over the remaining term of the Note Purchase Agreement. The retrospective adoption resulted in $0.9 million of debt issuance costs being reclassified from other current assets and other non-current assets to a reduction of the carrying value of long-term debt as of December 31, 2015. The Company also adopted ASU No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, and elected not to reclassify the debt issuance costs related to line-of-credit arrangements for the 2015 Credit Agreement.
