Fair value hierarchy The Company measures its financial instruments at fair value. The Company’s cash equivalents are classified within Level 1 of the fair value hierarchy as they are valued primarily using quoted market prices utilizing market observable inputs. The Company's foreign currency contracts are classified within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments. The Company's contingent consideration liability is classified as Level 3 as valuation inputs are unobservable in the market and significant to the instrument’s valuation. During the nine months ended September 30, 2016, the Company paid $3.0 million for contingent consideration and recorded $0.1 million for accrued interest.

Net investment in sales-type leases. The carrying amount of the Company's sales-type lease receivables is a reasonable estimate of fair value as the unearned interest income is immaterial. Interest Rate Swap Contracts The Company uses interest rate swap agreement to protect the Company against adverse fluctuations in interest rates by reducing its exposure to variability in cash flows relating to interest payments on a portion of its outstanding debt. The Company's interest rate swaps, which are designated as cash flow hedges, involve the receipt of variable amounts from counterparties in exchange for the Company making fixed-rate payments over the life of the agreements. The Company does not hold or issue any derivative financial instruments for speculative trading purposes. During 2016, the Company entered into an interest rate swap agreement with a combined notional amount of $100.0 million with one counter-party that is effective beginning on June 30, 2016 and maturing on April 30, 2019. The swap agreement requires the Company to pay a fixed rate of 0.8% and provides that the Company will receive a variable rate based on the one month LIBOR rate subject to LIBOR floor of 0.0%. Amounts payable by or due to the Company will be net settled with the respective counter-party on the last business day of each month, commencing July 31, 2016. The fair value of the interest rate swap agreements at September 30, 2016 were $0.1 million and there were no amounts reclassified into current earnings due to ineffectiveness during the periods presented.
