The amount due to Arthrex consists of payments collected on Angel sales made by Nuo Therapeutics, on behalf of Arthrex, during the transition services period (See Note 2 – Arthrex Distributor and License agreement for additional details.).
 
Accrued interest primarily consists of the interest accrued related to the Deerfield convertible debt (See Note 11 – Debt for additional details.).
 
We expect to incur machine refurbishment and design improvement costs to refurbish customer placed centrifuges, therefore, an accrual of $600,000 was established for these expected costs and is reflected in “cost of sales” on the statement of operations.
