For discussion of income tax accounting policies and other income tax related information, see Note 2 on page 118, and Note 20 on pages 166 - 168, of our 2015 Form 10-K.

For the three and six months ended March 31, 2016, our effective income tax rate is 36.5% and 36.6%, respectively, each of which is slightly lower than the 37.1% effective tax rate for fiscal year 2015. The primary factor for the decrease in the current period effective tax rates compared to the prior year effective tax rate is the favorable impact in the current period of the income associated with our company-owned life insurance which is not subject to tax. In fiscal year 2015, such investments generated non-deductible losses.

As of March 31, 2016, our uncertain tax position liability balance decreased by $2.4 million from the September 30, 2015 level, as a result of the resolution of certain state tax audits. We anticipate that the uncertain tax position liability balance may further decrease by $3.9 million over the next twelve months as a result of the resolution of other state tax audits.
