The Company’s level 2 financial instruments included in the tables above as of December 31, 2018 and 2017 consist of the Company’s rabbi trust established for GEO employee and employer contributions to The GEO Group, Inc. Non-qualified Deferred Compensation Plan, interest rate swaps held by our Australian subsidiaries and an investment in Canadian dollar denominated fixed income securities. The Company's restricted investment in the Rabbi Trust is invested in Company owned life insurance policies which are recorded at their cash surrender values. These investments are valued based on the underlying investments held in the policies' separate account. The Australian subsidiaries' interest rate swaps are valued using a discounted cash flow model based on projected Australian borrowing rates. The Canadian dollar denominated securities, not actively traded, are valued using quoted rates for these and similar securities.

During the year ended December 31, 2018, the Company transferred certain accounts receivable balances that had a carrying value of approximately $6.9 million to an unrelated third party.
