Guarantees</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt"><i>Warranty</i> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">ARRIS provides warranties of various lengths to customers based on the specific product and the terms of individual agreements. The Company provides for the estimated cost of product warranties based on historical trends, the embedded base of product in the field, failure rates, and repair costs at the time revenue is recognized. Expenses related to product defects and unusual product warranty problems are recorded in the period that the problem is identified. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its suppliers, the estimated warranty obligation could be affected by changes in ongoing product failure rates, material usage and service delivery costs incurred in correcting a product failure, as well as specific product failures outside of ARRIS’ baseline experience. If actual product failure rates, material usage or service delivery costs differ from estimates, revisions (which could be material) would be recorded to the warranty liability. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">The Company offers extended warranties and support service agreements on certain products. Revenue from these agreements is deferred at the time of the sale and recognized on a straight-line basis over the contract period. Costs of services performed under these types of contracts are charged to expense as incurred, which approximates the timing of the revenue stream. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">Information regarding the changes in ARRIS’ aggregate product warranty liabilities for the six months ended June 30, 2010 was as follows (in thousands): </div> <div align="center"> <table style="font-size: 10pt; text-align: left" cellspacing="0" border="0" cellpadding="0" width="100%">  <tr valign="bottom"> <td width="88%"> </td> <td width="5%"> </td> <td width="1%"> </td> <td width="5%"> </td> <td width="1%"> </td> </tr>   <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Balance at December 31, 2009 </div></td> <td> </td> <td align="left">$</td> <td align="right">7,679</td> <td> </td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">Accruals related to warranties (including changes in estimates) </div></td> <td> </td> <td> </td> <td align="right">1,330</td> <td> </td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Settlements made (in cash or in kind) </div></td> <td> </td> <td nowrap="nowrap" align="left"> </td> <td align="right">(2,320</td> <td nowrap="nowrap">)</td> </tr> <tr style="font-size: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 1px solid #000000"> </td> <td> </td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">Balance at June 30, 2010 </div></td> <td> </td> <td align="left">$</td> <td align="right">6,689</td> <td> </td> </tr> <tr style="font-size: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 3px double #000000"> </td> <td> </td> </tr>  </table> </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Disclosure for standard and extended product warranties and other product guarantee contracts, including a tabular reconciliation of the changes in the guarantor's aggregate product warranty liability for the reporting period.
