The Company maintains a non-qualified Deferred Compensation Plan for highly compensated employees. The assets of the plan are held in the name of CDI at a third-party financial institution. Separate accounts are maintained for each participant to reflect the amounts deferred by the participant and all earnings and losses on those deferred amounts. The assets of the plan are held in publicly traded mutual funds. The fair value of the plan assets is calculated using the market price of the mutual funds as of the end of the period.

The following tables summarize the assets and liabilities measured at fair value on a recurring basis by level of the fair value hierarchy for the indicated periods:
