Contract Liabilities

The Company’s contract liabilities largely relate to a prepayment of $13.9 million received in April 2020 from the CMS as part of the Accelerated and Advance Payment Program of the CARES Act.

On October 1, 2020, the President of the United States signed the “Continuing Appropriations Act, 2021 and Other Extensions Act,” which relaxed a number of the Medicare Accelerated and Advance Payment Programs recoupment terms for providers and suppliers that received funds from the program. Starting in April 2021, Medicare began to recoup 25% of Medicare payments otherwise owed to the provider or supplier for submitted claims. After 11 months, recoupment will increase to 50% for another 6 months. Thus, during these time periods, rather than receiving the full amount of payment for newly submitted claims, the Company’s outstanding accelerated / advance payment balance will be reduced by the recoupment amount until the full balance has been repaid.

As of June 30, 2021, the balance of the contract liability associated with the Accelerated and Advance Payment Program of the CARES Act totaled $11.0 million. The Company has classified the entire balance of this contract liability within other current liabilities based upon the Company’s estimates of when such funds will be recouped.

The following table provides a detail of changes in the Company’s contract liability associated with the Accelerated and Advanced Payment Program for the three and six months ended June 30, 2021 and 2020:

(U.S. Dollars, in thousands)	Three Months Ended June 30,					Six Months Ended June 30,

Contract liability ending balance	$	10,971		$	13,851	$	10,971		$	13,851

Other Contract Assets

The Company’s contract assets, excluding trade accounts receivable (“Other Contract Assets”), largely consist of payments made to certain distributors to obtain contracts, gain access to customers in certain territories, and to provide the benefit of the exclusive distribution of Orthofix products. Other Contract Assets are included in other long-term assets or other current assets, dependent upon the original term of the related agreement, and totaled $1.5 million and $2.0 million as of June 30, 2021 and December 31, 2020, respectively.
