a decline in iPhone ASPs during 2013. 

The year-over-year growth in iPhone net sales and unit sales during 2012 reflects strong demand for iPhone in all of the Company’s operating segments, except for the Rest of Asia Pacific segment. Growth in iPhone sales during 2012 is primarily a result of the launches of iPhone 4s in the first quarter of 2012 and iPhone 5 in the fourth quarter of 2012, ongoing demand during 2012 for iPhone 4 and iPhone 3GS, and expanded distribution with new carriers and resellers.
