0.25% Convertible Senior Notes

On August 24, 2017, the Company entered into a purchase agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative of the several initial purchasers named therein (collectively, the “Initial Purchasers”), to issue and sell $300 million aggregate principal amount of our 0.25% convertible senior notes due 2022 (the "Notes") in a private placement to qualified institutional buyers within the meaning of Rule 144A under the Securities Act of 1933, as amended. In addition, we granted the Initial Purchasers a 30-day option to purchase up to an additional $45 million aggregate principal amount of the Notes (the “Over-Allotment Option”).

On August 29, 2017, the Initial Purchasers exercised their Over-Allotment Option to purchase the entire $45 million in aggregate principal amount of additional Notes. The Notes mature on September 1, 2022, unless earlier repurchased by the Company or converted by holders in accordance with the terms of the Notes. Interest is payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2018.

The sale of the Notes to the Initial Purchasers settled on August 29, 2017, and resulted in approximately $336 million in net proceeds to the Company after deducting the initial purchasers’ discount and the estimated offering expenses. The net proceeds from the offering and sale of the Notes were used, in part, to repurchase approximately $49.9 million of our Common Stock. The Company used the remaining net proceeds to repay $252 million on its revolving credit facility and to pay debt issuance costs of $10.1 million.

The Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank, National Association, as trustee. The Notes are our senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of our indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure secured debt will be available to pay obligations on the Notes only after all indebtedness under such secured debt has been repaid in full from such assets. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of our Common Stock or a combination of cash and shares of our Common Stock, at the Company’s election.

As a result of our cash conversion option, the Company separately accounted for the value of the embedded conversion option as a debt discount. The value of the embedded conversion option was determined based on the estimated fair value of the debt without the conversion feature, which was determined using an expected present value technique (income approach) to estimate the fair value of similar nonconvertible debt; the debt discount is being amortized as additional non-cash interest expense over the term of the Notes using the effective interest method with an effective interest rate of 4.5% per annum.

The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The initial conversion rate is 21.25 shares of Common Stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of $47.06 per share of Common Stock. Throughout the term of the Notes, the conversion rate may be adjusted upon the occurrence of certain events.

Holders of the Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited.

Prior to the close of business on the business day immediately preceding June 1, 2022, the Notes will be convertible only upon satisfaction of at least one of the conditions as follows:

During any fiscal quarter (and only during such fiscal quarter), if the last reported sale price of our Common Stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

During the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our Common Stock and the conversion rate on each such trading day; or

Upon the occurrence of specified corporate events.

On or after June 1, 2022 until the close of business on the business day immediately preceding the maturity date, holders may convert all or any portion of their Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances.

As of March 31, 2018, the Notes are not yet convertible. The Notes will become convertible upon the satisfaction of at least one of the above conditions. In accounting for the transaction costs related to the Note issuance, the Company allocated the total amount of offering costs incurred to the debt and equity components based on their relative values. Offering costs attributable to the debt component, totaling $8.4 million, are being amortized as non-cash interest expense over the term of the Notes, and offering costs attributable to the equity component, totaling $1.7 million, were recorded within Shareholders' equity.

The following table sets forth total interest expense recognized related to the Notes for the three and nine months ended March 31, 2018:

	Three Months Ended March 31, 2018		Nine Months Ended March 31, 2018
0.25% contractual coupon	$	216	$	513
Amortization of debt discount and debt issuance costs including initial purchaser discount		2,974		7,017
Interest expense	$	3,190	$	7,530

Amended Credit Facility

On July 28, 2016, the Company amended and restated its existing credit agreement. The Third Amended and Restated Credit Agreement (the “Amended Credit Facility”) provides for a revolving credit facility of $325 million, as well as a $100 million term loan. The term loan is being repaid in consecutive quarterly principal payments on the first business day of each January, April, July and October, with the first payment having commenced on October 1, 2016, as follows: (i) twenty consecutive quarterly installments of $5 million and (ii) a final installment of all remaining principal due and payable on the maturity date of July 27, 2021. Amounts borrowed under the revolving credit facility are due and payable on the maturity date. The Amended Credit Facility is unsecured, but is guaranteed by each existing and subsequently acquired or organized wholly-owned domestic subsidiary of the Company. The Company has the option to request an increase to the size of the revolving credit facility in an aggregate additional amount not to exceed $100 million. The Amended Credit Facility has a five-year term through July 27, 2021 and has an interest rate of either a Base Rate Option or a Euro-Rate Option, plus an Applicable Margin, as defined in the agreement governing the Amended Credit Facility. If the Base Rate option is selected for a borrowing, the Applicable Margin is 0.00% to 1.25% and if the Euro-Rate Option is selected for a borrowing, the Applicable Margin is 1.00% to 2.25%. The Applicable Margin is based on the ratio of the Company’s consolidated indebtedness to consolidated EBITDA. Additionally, the Credit Facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As of March 31, 2018, the Company was in compliance with all financial covenants under its Amended Credit Facility.

Yen Loan

The Company’s Yen denominated line of credit is a 500 million Yen (approximately $4.7 million) facility. The Yen line of credit matures in August 2020. The interest rate is equal to LIBOR, as defined in the loan agreement, plus 0.625% to 1.75%. At March 31, 2018 and June 30, 2017, the Company had 300 million Yen borrowed. Additionally, the facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As of March 31, 2018, the Company was in compliance with all financial covenants under its Yen facility.

Note Payable

In conjunction with the acquisition of IPI, the Company assumed a non-interest bearing note payable owed to a major customer of IPI. The agreement if not terminated early by either party is payable in full in May 2019.

Aggregate Availability

The Company had aggregate availability of $236.4 million and $73.5 million under its lines of credit as of March 31, 2018 and June 30, 2017, respectively. The amounts available under the Company’s lines of credit are reduced by outstanding letters of credit. The total outstanding letters of credit supported by these credit facilities were $0.4 million and $1.2 million as of March 31, 2018 and June 30, 2017, respectively.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 1.4% and 2.3% for the nine months ended March 31, 2018 and 2017, respectively.
