3.	FAIR VALUE MEASUREMENTS

When determining fair value, the Company uses a three-tier value hierarchy which prioritizes the inputs used in measuring fair value. Whenever possible, the Company uses observable market data. The Company relies on unobservable inputs only when observable market data is not available. Classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.

Level 1 - Money market mutual funds are recorded at fair value based upon quoted market prices.

Level 2 - The asset or liability related to the interest rate swap is recorded at fair value based upon a valuation model that uses relevant observable market inputs at quoted intervals, such as forward yield curves.

Level 3 - The contingent liability associated with the acquisition of CEBOS is recorded at fair value based on significant inputs that are not observable in the market. This measure includes an assessment of the probability of achieving certain milestones and discounting the amount of each potential payment based on expected timing of the payment. Key assumptions include a discount rate of 4.6%, probability of achieving profitability and probability of achieving product development goals. As of January 31, 2015, there was one remaining future payment due April 2015 which consisted of a guaranteed payment of $0.3 million and $0.5 million contingent upon certain milestones. The maximum contingent liability of $0.8 million was paid in March 2015.

The following table sets forth the financial assets, measured at fair value, as of July 31, 2015 and January 31, 2015:

	Fair value measurement at reporting date using
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
	(in thousands)
Money market mutual funds as of July 31, 2015	$	110,476
Money market mutual funds as of January 31, 2015	$	98,294
Liability related to the interest rate swap as of July 31, 2015			$	(275	)
Liability related to the interest rate swap as of January 31, 2015			$	(626	)
Contingent liability associated with acquisitions as of July 31, 2015						$	-
Contingent liability associated with acquisitions as of January 31, 2015						$	(750	)

Money market mutual funds are classified as part of “Cash and equivalents” in the accompanying Condensed Consolidated Balance Sheets. In addition, the amount of cash and equivalents, including cash deposited with commercial banks, was $20 million and $22 million as of July 31, 2015 and January 31, 2015, respectively.

The Company’s line of credit and notes payable both bear a variable market interest rate commensurate with the Company’s credit standing. Therefore, the carrying amounts outstanding under the line of credit and note payable reasonably approximate fair value based on Level 2 inputs.

There have been no transfers between fair value measurements levels during the six months ended July 31, 2015.

Derivative Instruments

The Company entered into an interest rate swap in May 2012 to mitigate the exposure to the variability of one month LIBOR for its floating rate debt described in Note 6 “Debt” within these Notes to Condensed Consolidated Financial Statements. The fair value of the interest rate swap is reflected as an asset or liability in the Condensed Consolidated Balance Sheets and the change in fair value is reported in “Other (income) expense” in the Condensed Consolidated Statements of Income and Comprehensive Income. The fair value of the interest rate swap is estimated as the net present value of projected cash flows based upon forward interest rates at the balance sheet date.

The fair values of the derivative instrument at July 31, 2015 and January 31, 2015 were as follows (in thousands):

	(Liability) Derivative
		Fair Value
	Balance Sheet Location	July 31, 2015				January 31, 2015
Derivative instrument:
Interest rate swap	Other liabilities		$	(275	)	$	(626	)
Total			$	(275	)	$	(626	)

The change in fair value of the interest rate swap recognized in the Condensed Consolidated Statements of Income and Comprehensive Income for the six months ended July 31, 2015 and 2014 was $351,000 and $(107,000), respectively.
