Standard Product Warranty, Policy [Policy Text Block]

Product Warranties: The Company offers a warranty on various products; the most significant of which relate to pacemaker and ICD systems. The Company estimates the costs that may be incurred under its warranties and records a liability in the amount of such costs at the time the product is sold. Factors that affect the Company's warranty liability include the number of units sold, historical and anticipated rates of warranty claims and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.
