M&T Bank Credit Facilities

Effective as of May 5, 2017, the Company and M&T Bank entered into the Third Amendment to Fifth Amended and Restated Credit Agreement (the “Third Amendment”), that amended the Fifth Amended and Restated Credit Agreement dated as of December 14, 2015, as amended by the First Amendment to Fifth Amended and Restated Credit Facility, dated as of June 20, 2016, and the Second Amendment to Fifth Amended and Restated Credit Facility agreement dated as of November 28, 2016 (“Fifth Amended Credit Agreement”). The Third Amendment extended the Revolver termination date to May 5, 2022. In connection with the Third Amendment, the Term Loan B to M&T Bank was amended and restated. The Third Amendment revised certain covenants to provide that the Company may use Revolver proceeds to refinance existing indebtedness. As a result, the Term Loan B, which matures on May 5, 2022, now has a principal amount of $6.0 million, of which $5.7 million was outstanding as of September 30, 2017. The Third Amendment also revised the maximum amount the Company can borrow under the Revolver to the lesser of $16.0 million or 85% of eligible receivables plus up to $7.0 million of eligible inventories. The Third Amendment also modified the definitions of Applicable Margin and Applicable Unused Fee to provide that each is calculated using the applicable Fixed Charge Coverage Ratio, as redefined by the Third Amendment. The Third Amendment established a Borrowing Base computed using monthly Borrowing Base Reports that, if inaccurate, allow M&T Bank, in its discretion, to suspend the making of or limit Revolving Credit Loans. Further, the Third Amendment provides for the Company’s repurchase of its common stock under certain circumstances without M&T Bank’s prior written consent.

Individual debt facilities provided under the Third Amendment, are described below:


a)	Revolving Credit Facility (“Revolver”): Up to $16.0 million is available through May 5, 2022. The maximum amount the Company may borrow is determined based on a borrowing base calculation described below.


b)	Term Loan A: $10.0 million was borrowed on January 18, 2013. Principal is being repaid in 108 equal monthly installments of $93 thousand. The proceeds of the sale-leaseback transaction described in Note 12—Capital Lease were used to pay down the loan, which was paid off in due course on January 1, 2017.


c)	Term Loan B: $14.0 million was borrowed on January 18, 2013. Principal is being repaid in 120 equal monthly installments of $117 thousand. As part of the Third Amendment, the principal was modified from $8.0 million to $6.0 million and principal is being repaid in equal monthly installments of $71 thousand plus a balloon payment of $1.6 million. The maturity date of the loan is May 5, 2022.


d)	Albuquerque Mortgage Loan: $4.0 million was borrowed on December 16, 2009. The loan is secured by real property in Albuquerque, NM, and principal was being repaid in equal monthly installments of $22 thousand plus a balloon payment of $1.8 million due at maturity. The loan was repaid in connection with the sale-leaseback transaction described in Note 12—Capital Lease.


e)	Celmet Building Term Loan: $1.3 million was borrowed on November 8, 2013 pursuant to an amendment to the 2013 Credit Agreement. The proceeds were used to reimburse the Company’s cost of purchasing its Rochester, New York facility. Principal is being repaid in 59 equal monthly installments of $11 thousand plus a balloon payment of $672 thousand due at maturity on November 7, 2018.

The Credit Facility is secured by a general security agreement covering the assets of the Company and its subsidiaries, a pledge of the Company’s equity interest in its subsidiaries, a negative pledge on the Company’s real property, and a guarantee by the Company’s subsidiaries, all of which restrict use of these assets to support other financial instruments.

Borrowing Base

Under the Third Amendment, the maximum amount the Company can borrow under the Revolver is the lesser of (i) 85% of eligible receivables plus a percentage of eligible inventories (up to a cap of $7.0 million) or (ii) $16.0 million at September 30, 2017 and $20.0 million at September 30, 2016.

At September 30, 2017, the upper limit on Revolver borrowings was $16.0 million, with $7.2 million available. At September 30, 2016, the upper limit on Revolver borrowings was $16.4 million with $12.4 million available. Average Revolver balances amounted to $6.1 million and $8.3 million during the years ended September 30, 2017 and September 30, 2016, respectively.

Interest Rates

Under the Third Amendment, variable rate debt accrues interest at LIBOR plus the applicable marginal interest rate that fluctuates based on the Company’s Fixed Charge Coverage Ratio, as defined below. Under the Third Amendment, the applicable marginal interest rate was fixed on May 5, 2017 through the fiscal quarter ending March 31, 2018, as follows: 2.50% for the Revolver and 2.75% for Term Loan B. Changes to applicable margins and unused fees resulting from the Fixed Charge Coverage Ratio generally become effective mid-way through the subsequent quarter.

The Company incurs quarterly unused commitment fees ranging from 0.250% to 0.375% of the excess of $16.0 million over average borrowings under the Revolver. Fees incurred amounted to $50.0 thousand and $57.7 thousand during the years ended September 30, 2017 and September 30, 2016, respectively. The fee percentage varies based on the Company’s Fixed Charge Coverage Ratio, as defined below.

Financial Covenants

The Third Amendment, also contains various affirmative and negative covenants including financial covenants. Pursuant to the Third Amendment, as of March 31, 2017, certain financial covenants of the credit facility were eliminated or revised to be less complex, including the Maximum Inventory covenant, Debt to EBITDAS ratios, and the Maximum Capital Expenditures limit after the fiscal year ending September 30, 2017. The Company is required to maintain a minimum fixed charge coverage ratio (“Fixed Charge Coverage Ratio”) that compares (i) EBITDAS minus unfinanced capital expenditures minus taxes paid, to (ii) the sum of interest expense, principal payments, payments on all capital lease obligations and dividends, if any (fixed charges). “EBITDAS” is defined as earnings before interest, taxes, depreciation, amortization and non-cash stock compensation expense. The Fixed Charge Coverage Ratio is generally measured quarterly on a rolling twelve month basis but was initially measured for a trailing six months ended September 30, 2017 and will be measured for a trailing nine months ending December 31, 2017. Additionally, pursuant to the Third Amendment, the Company was required to maintain a maximum amount of capital expenditures on an annual basis for fiscal 2017 that was eliminated for future periods.

Covenant ratios in effect at September 30, 2017, pursuant to the Fifth Amended Credit Agreement, as amended by the Third Amendment, are as follows:



Debt Covenant		Limit

Fixed Charge Coverage Ratio		Minimum 1.10x
Maximum Capital Expenditures		Maximum $3.5 million annually

The Third Amendment provides for customary events of default, subject in certain cases to customary cure periods, in which the outstanding balance and any unpaid interest would become due and payable.

The Company was in compliance with all financial debt covenants at September 30, 2017.

When IEC acquired Albuquerque, the Company assumed responsibility for a $100 thousand Industrial Revenue Bond issued by the City of Albuquerque.
