(a) The fair value of foreign currency forward exchange contracts is based on dealer quotes of market forward rates and reflects the amount that the Company would receive or pay at their maturity dates for contracts involving the same currencies and maturity dates.

(b) This represents purchase obligations and contingent consideration related to the Company’s various acquisitions. This is based on a probability weighted performance approach and it is adjusted to fair value on a recurring basis and any adjustments are included as a component of operating income in the statement of operations. These amounts were mainly calculated using unobservable inputs such as future earnings performance of the Company’s various acquisitions and the expected timing of the payment.

(c) The fair value of the interest rate swap is based on dealer quotes of market forward rates and reflects the amount that the Company would receive or pay as of March 31, 2019 for contracts involving the same attributes and maturity dates.              

(d) The fair value of equity method investment represents an equity method investment acquired during the six months March 31, 2019 whereby the Company has elected the fair value option under ASC 825 – Financial Instruments.  The valuation is based upon quoted prices in active markets and model-based valuation techniques to determine fair value.
