Fair Value Disclosures [Abstract]
Fair value	Note 3. Fair value The fair value of the Company’s external debt under its Credit Agreement approximates its carrying value because the terms and conditions approximate the terms and conditions of current market debt available to the Company. Due to the floating interest rate the debt is classified as Level 2 of the fair value hierarchy. The external debt was estimated based on the current rates offered to the Company for debt with the same remaining maturities. The fair value of the Company’s Credit Agreement was $65.3 million and $57.8 million as of December 31, 2019 and September 30, 2020, respectively. The fair value of cash approximates its carrying value (Level 1 of the fair value hierarchy). The Company’s Level 3 liability for contingent consideration of $3.0 million that was added during the three-month period ended September 30, 2019 was fully paid to Riverbed Technology, Inc. as of February 2020 in consideration for the sale to the Company of the Xirrus business. The entire $3.0 million was earned as of December 31, 2019 and the Company made a payment of $2.7 million in November 2019 and paid the remaining $0.3 million in February 2020.
