[1] During the three months ended March 31, 2012, the effective tax rate was impacted by net favorable discrete items of $3.6 million, or 0.7 percentage points. This included the favorable impact of settlement of federal, foreign and state tax controversies ($36.3 million), a favorable impact from the related reduction for interest on unrepatriated foreign earnings ($8.5 million), and a net unfavorable impact of remeasuring some current and prior years unrecognized tax benefits primarily as a result of ongoing negotiations with tax authorities ($43.8 million).

[2] During the three months ended March 31, 2011, the effective tax rate was unfavorably impacted by net discrete items of $16.5 million, or 3.9 percentage points, primarily attributable to changes in state tax rules and deferred tax rate changes in certain foreign and state jurisdictions.

[3] During the nine months ended March 31, 2012, the effective tax rate was impacted by net unfavorable discrete items of $4.8 million, or 0.4 percentage points. The discrete items included unfavorable amounts related to remeasuring certain unrecognized tax benefits, partially offset by the favorable impact of settling certain federal, state, and foreign tax matters.

[4] During the nine months ended March 31, 2011, the effective tax rate was favorably impacted by net discrete items of $26.8 million, or 2.3 percentage points, primarily attributable to recognizing no income tax expense on the sale of CareFusion stock due to the release of a previously established deferred tax valuation allowance.
