United States Debt

On August 27, 2013, 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”) comprised of a $65.0 million senior secured term loan, a $70.5 million senior secured U.S. dollar revolving credit facility for U.S. dollar revolving loans with sub-facilities for letters of credit and swing-line loans, and a $19.5 million senior secured multi-currency revolving credit facility for U.S. dollar and specific foreign currency loans.

Concurrent with the closing of our Met-Pro Corporation (“Met-Pro”) acquisition on August 27, 2013, the Company borrowed $65.0 million in term loans and $52.0 million in U.S. dollar revolving loans and used the proceeds to (i) finance the cash portion of the acquisition, (ii) pay off certain outstanding indebtedness of the Company and its subsidiaries (including certain indebtedness of Met-Pro and its subsidiaries), and (iii) pay certain fees and expenses incurred in connection with the Credit Agreement and the acquisition.

On November 18, 2014, the Company amended the Credit Agreement. 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 LLC 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 further amended the Credit Agreement. Pursuant to the amendment, the Lenders provided a term loan under the Credit Agreement 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 March 31, 2016 and December 31, 2015, $12.9 million and $15.4 million of letters of credit were outstanding, respectively. Total unused credit availability under the Credit Facility was $61.1 million and $56.6 million at March 31, 2016 and December 31, 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 3.44% and 3.42% at March 31, 2016 and December 31, 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 indexed to LIBOR market rates. The fair value of the interest rate swap was a liability totaling $1.1 million and $0.4 million at March 31, 2016 and December 31, 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, and accordingly the change in the fair value until the date of designation of $0.5 million was recorded in earnings in “Other income (expense), net” in the Consolidated Statements of Income for the three-month period ended March 31, 2016. From the date of designation, all changes to the fair value of the interest rate swap have been recorded in other comprehensive income (loss) 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 is set to decrease to 3.50 by June 30, 2016, and then decrease again to 3.00 by December 31, 2017. The consolidated leverage ratio will then remain at 3.00 until the end of the term of the Credit Agreement. 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 March 31, 2016 and December 31, 2015, the Company was in compliance with all related financial and other restrictive covenants under the Credit Agreement.

The Company has paid $6.0 million of customary closing fees, arrangement fees, administration fees, letter of credit fees and commitment fees for the Credit Agreement and amendments thereto. As of March 31, 2016 and December 31, 2015, unamortized deferred financing costs of $4.0 million and $4.2 million, respectively, are included as a discount to debt in the accompanying Condensed Consolidated Balance Sheets. Amortization expense was $0.2 million and $0.1 million for the three-month periods ended March 31, 2016 and 2015, respectively, and is classified as interest expense.
