The Company has trade receivables with various individual customers such as private businesses, hospitals, universities, government and non-profit entities, and distributors. The Company has determined that geography is the similar risk characteristic to pool our trade receivables balances, and accordingly, groups such balances into either the domestic pool or the international pool. The domestic pool is primarily comprised of individual customers, and the international pool is primarily comprised of distributors.

The allowance for credit losses represents an estimate of the lifetime expected credit losses inherent in trade receivables as of the balance sheet date. We assess the adequacy of the allowance for credit losses on a quarterly basis based on historical information and current economic conditions and forecasts. Subsequent changes in the allowance for credit losses are recorded in current earnings and reversal of previous losses are permitted under the current guidance.

While we believe we have exercised prudent judgment and applied reasonable assumptions, there can be no assurance that in the future, changes in economic conditions or other factors would not cause changes in the financial health of our customers. If the financial health of our customers deteriorates, the timing and level of payments received could be impacted and therefore, could result in a change to our estimated losses.
