7. Product Warranties

The Company offers a one-year warranty on all Keurig® Single Cup brewers it sells. The Company provides for the estimated cost of product warranties, primarily using historical information and repair or replacement costs, at the time product revenue is recognized. Brewer failures may arise in the later part of the warranty period, and actual warranty costs may exceed the reserve. As the Company has grown, it has added significantly to its product testing, quality control infrastructure and overall quality processes. Nevertheless, as the Company continues to innovate, and its products become more complex, both in design and componentry, product performance may modulate, causing warranty rates to possibly fluctuate going forward. As a result, future warranty claims rates may be higher or lower than the Company is currently experiencing and for which the Company is currently providing in its warranty reserve.
