[1] Included in cash and cash equivalents on the Consolidated Balance Sheets.

[2] The Company has an interest rate swap contract that hedges the risk of variability from interest payments on its borrowings (refer to Note 4 – Debt and Note 7 – Derivatives and Hedging). The fair value of the interest rate swap is based on valuations prepared by a third-party broker. Those valuations are based on observable interest rates and other observable market data, which the Company considers Level 2 inputs.

[3] Marketable investments have been initially valued at the transaction price and subsequently valued, at the end of the reporting period, utilizing third party pricing services or other market observable data. The pricing services utilize industry standard valuation methods, including both income and market-based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events.
