the Company is 

 subject to various legal proceedings and claims that arise in the ordinary course of business. The Company records a contingent liability when it is probable that a loss has been incurred and the amount is reasonably estimable in accordance with SFAS No. 5, Accounting for Contingencies . There is significant judgment required in both the probability determination and as to whether an exposure can be reasonably estimated. In management's opinion, the Company does not have a potential liability related to any current legal proceedings and claims that would individually or in the aggregate have a material adverse effect on its financial condition or operating results. However, the outcomes of legal proceedings and claims brought against the Company are subject to significant uncertainty. Should the Company fail to prevail in any of these legal matters or should several of these legal matters be resolved against the Company in the same reporting period, the operating results of a particular reporting period could be materially adversely affected.

Unit sales of the Company's portable products accounted for 62% of the Company's personal computer shipments in 2007, up from 54% in 2006. Net sales and unit sales of the Company's portable products increased 55% and 51%, respectively, during 2007 compared to 2006. This growth was due to strong demand for the MacBook, which increased in each of the Company's operating segments, as well as the MacBook Pro, which increased in each operating segment except Japan. Mac desktop net sales and unit sales increased by 21% and 12%, respectively, during 2007 due to stronger sales of the iMac in each of the Company's operating segments.
