⁽¹⁾ Included in cash and cash equivalents.

⁽²⁾ Nonqualified deferred compensation plan investments consist of U.S. and international equity mutual funds, government and corporate bond mutual funds, and money market funds which are held in a trust with a third‑party brokerage firm. Included in other long‑term assets, with a corresponding liability reported within other long‑term liabilities.

⁽³⁾ Included in other long‑term assets. The fair values of the interest rate swaps were determined by discounting future cash flows and receipts based on expected interest rates observed in market interest rate curves adjusted for estimated credit valuation considerations reflecting nonperformance risk of the Company and the counterparty, which are considered to be in Level 3 of the fair value hierarchy. The Company assessed Level 3 inputs as insignificant to the valuation at December 31, 2018 and 2017 and considers the interest rate swap valuations in Level 2 of the fair value hierarchy.

⁽⁴⁾ Included in accrued expenses. At December 31, 2018, the fair value of the contingent consideration for an earn-out agreement related to the September 2016 acquisition of LDS represents the final accrued payment and was based on calculations performed for the earn-out period which ended August 31, 2018. Prior to the end of the earn-out period, the estimated fair value of contingent consideration was determined by assessing Level 3 inputs with a discounted cash flow approach using various probability-weighted scenarios. As of December 31, 2017, the Level 3 assessments utilized a Monte Carlo simulation with inputs including scenarios of estimated revenues and gross margins to be achieved for the applicable performance periods, probability weightings assigned to the performance scenarios, and the discount rate applied of 12.5%.
