United States Debt

The Company entered into a credit agreement (the “Credit Agreement”) with various lenders (the “Lenders”) and letter of credit issuers (each, an “L/C Issuer”), and Bank of America, N.A., as Administrative Agent (the “Agent”), swing line lender and an L/C Issuer, providing for various senior secured credit facilities (collectively, the “Credit Facility”).

The Company amended the Credit Agreement in 2014. Pursuant to the amendment (i) certain lenders provided an additional term loan under the Credit Agreement in an aggregate principal amount of $35.0 million and certain lenders increased their revolving credit commitments in an aggregate principal amount of up to $15.0 million, and (ii) the Credit Agreement was amended to, among other things, (a) modify the calculation of Consolidated EBITDA to include certain pro forma adjustments related to certain acquisitions and other transactions, (b) modify the Consolidated Leverage Ratio covenant and (c) permit additional investments in foreign subsidiaries and additional indebtedness by foreign subsidiaries. The proceeds from the additional term loan were used primarily to finance the acquisition of Emtrol and related expenses. Additionally, the Company has the option to obtain additional commitments for either the U.S. dollar revolving credit facility or the term loan facility in an aggregate principal amount not to exceed $50.0 million.

On September 3, 2015, concurrent with the closing of the PMFG acquisition, the Company amended and restated the Credit Agreement. Pursuant to the amended and restated Credit Agreement, the Lenders provided a term loan in an aggregate principal amount of $170.0 million and the Lenders decreased their senior secured U.S. dollar revolving credit commitments to the aggregate principal amount of $60.5 million. All other provisions of the agreement remained substantially unchanged. The proceeds from the increased term loan were used primarily to (i) finance the cash portion of the PMFG purchase price, (ii) pay off certain outstanding indebtedness of the Company and its subsidiaries (including certain indebtedness of PMFG and its subsidiaries), and (iii) pay certain fees and expenses incurred in connection with the amendment to the Credit Agreement and the PMFG acquisition.

As of December 31, 2016 and 2015, $18.0 million and $15.4 million of letters of credit were outstanding, respectively. Total unused credit availability under the Credit Facility was $62.0 million and $56.6 million at December 31, 2016 and 2015, respectively. Revolving loans may be borrowed, repaid and reborrowed until September 3, 2020, at which time all amounts borrowed pursuant to the Credit Facility must be repaid.

At the Company’s option, revolving loans and the term loans accrue interest at a per annum rate based on either the highest of (a) the federal funds rate plus 0.5%, (b) the Agent’s prime lending rate, and (c) one-month LIBOR plus 1.00%, plus a margin ranging from 1.0% to 2.0% depending on the Company’s consolidated leverage ratio (“Base Rate”), or a Eurocurrency Rate (as defined in the Credit Agreement) plus 2.0% to 3.0% depending on the Company’s consolidated leverage ratio. Interest on swing line loans is the Base Rate.

Accrued interest on Base Rate loans is payable quarterly in arrears on the last day of each calendar quarter and at maturity. Interest on Eurocurrency Rate loans is payable on the last date of each applicable Interest Period (as defined in the agreement), but in no event less than once every three months and at maturity. The weighted average interest rate on outstanding borrowings was 3.26% and 3.42% at December 31, 2016 and 2015, respectively.

In accordance with the Credit Facility terms, the Company entered into an interest rate swap on December 30, 2015 to hedge against interest rate exposure related to approximately one-third of the outstanding debt as of the date of the agreement indexed to LIBOR market rates. The fair value of the interest rate swap was a $0.2 million and $0.4 million liability at December 31, 2016, and 2015, respectively, which is recorded in “Accounts payable and accrued expenses” on the Consolidated Balance Sheets. The Company did not designate the interest rate swap as an effective hedge until the first quarter of 2016. The change in the fair value of the hedge prior to being designated as an effective hedge during the year ended December 31, 2016 and 2015 of $0.5 million and $0.4 million, respectively, was recorded in earnings in “Other income (expense), net” in the Consolidated Statements of Operations. From the date of designation, all changes to the fair value of the interest rate swap are recorded in other comprehensive income (loss) as long as the hedge is deemed effective.

The Company has granted a security interest in substantially all of its assets to secure its obligations pursuant to the Credit Agreement. The Company’s obligations under the Credit Agreement are guaranteed by the Company’s U.S. subsidiaries and such guaranty obligations are secured by a security interest on substantially all of the assets of such subsidiaries, including certain real property. The Company’s obligations under the Credit Agreement may also be guaranteed by the Company’s material foreign subsidiaries to the extent no adverse tax consequences would result to the Company.

The Credit Agreement contains customary affirmative and negative covenants, including the requirement to maintain compliance with a consolidated leverage ratio of less than 3.75 and a consolidated fixed charge coverage ratio of more than 1.25. Per the Credit Agreement, the consolidated leverage ratio decreased to 3.50 on December 31, 2016, and then is set to decrease again to 3.00 by December 31, 2017. The consolidated leverage ratio will then remain at 3.00 until the end Credit Agreement term. The Credit Agreement also includes customary events of default and the occurrence of an event of default could result in an increased interest rate equal to 2.0% above the applicable interest rate for loans, the acceleration of the Company’s obligations pursuant to the Credit Agreement and an obligation of the subsidiary guarantors to repay the full amount of the Company’s borrowings pursuant to the Credit Agreement.

As of December 31, 2016 and 2015, the Company was in compliance with all related financial and other restrictive covenants under the Credit Agreement.
