Other Current Receivables
Other current receivables include proceeds due from pharmacy rebates, CMS for Medicare Part D, reinsurance and other miscellaneous amounts due to the Company.
The Companys PBM companies contract with pharmaceutical manufacturers, some of whom provide rebates based on use of the manufacturers products by its PBM companies affiliated and non-affiliated clients. The Company accrues rebates as they are earned by its clients on a monthly basis based on the terms of the applicable contracts, historical data and current estimates. The PBM companies bill these rebates to the manufacturers on a monthly or quarterly basis depending on the contractual terms. The Company records rebates attributable to affiliated clients as a reduction to medical costs. Rebates attributable to non-affiliated clients are accrued as rebates receivable and a reduction of cost of products sold with a corresponding payable for the amounts of the rebates to be remitted to non-affiliated clients in accordance with their contracts and posted to the Consolidated Statements of Operations as a reduction of Product Revenue. The Company generally receives rebates between two to five months after billing.
