Fair Value Measurements

Note 7. Fair Value Measurements

The carrying amounts of accounts receivable and other current assets, accounts payable and accrued liabilities approximate their fair value due to their short-term nature.

Financial assets and liabilities recorded at fair value in the condensed consolidated financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities are as follows:

Level 1—Observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Financial assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires management to make judgments and considers factors specific to the asset or liability.

We determine the fair value of our security holdings based on pricing from our service providers and market prices from industry-standard independent data providers. The valuation techniques used to measure the fair value of financial instruments having Level 2 inputs were derived from non-binding consensus prices that are corroborated by observable market data or quoted market prices for similar instruments. Such market prices may be quoted prices in active markets for identical assets (Level 1 inputs) or pricing determined using inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs). We perform procedures to ensure that appropriate fair values are recorded such as comparing prices obtained from other sources.

Balance Sheet Hedges

We enter into foreign currency forward contracts (the “Forward Contracts”) in order to hedge our foreign currency exposure. A foreign currency forward contract is a commitment to deliver a certain amount of currency at a certain price on a specific date in the future. By entering into Forward Contracts and holding them to maturity, we are locked into a future currency exchange rate in an amount equal to and for the terms of the Forward Contracts. We account for derivative instruments at fair value with changes in the fair value recorded as a component of other income, net in our condensed consolidated statements of comprehensive income. Cash flows from such forward contracts are classified as operating activities. We recognized immaterial realized foreign currency gains during the three months ended April 30, 2019 on hedging, and gains of $0.5 million during the three months ended April 30, 2018 on hedging, respectively.

The fair value of our outstanding derivative instruments is summarized below (in thousands):

	April 30,			January 31,

Notional amount of foreign currency derivative contracts	$	(2,544	)	$	(5,112	)
