The company records estimated product warranty costs at the time of shipment of products to customers. Warranty reserves are primarily based on factors that include past claims experience, sales history, product manufacturing and engineering changes and industry developments. Liabilities for product recall campaigns are recorded at the time the company’s obligation is probable and can be reasonably estimated. Policy repair actions to maintain customer relationships are recorded as other liabilities at the time an obligation is probable and can be reasonably estimated. Product warranties, including recall campaigns, not expected to be paid within one year are recorded as a non-current liability.
