NOTE 11    INCOME TAXES

Our effective tax rates were approximately 22% and 25% for the three months ended December 31, 2010 and 2009, respectively, and 23% and 25% for the six months ended December 31, 2010 and 2009, respectively. The reduction in the rate was due to a higher mix of earnings taxed at lower rates in foreign jurisdictions, and the retroactive extension of the research and development tax credit in the United States. Tax contingencies and other tax liabilities were $6.9 billion as of December 31, 2010 and June 30, 2010, and were included in other long-term liabilities.
