(5) Income Taxes

The Company’s effective income tax rates for the six months ended March 31, 2016 and 2015, were 37.2% and 39.2%, respectively, and differ from the federal statutory rate of 35% primarily due to state taxes. The effective income tax rate was lower for the period ended March 31, 2016, due to changes in state apportionment factors.

We are subject to income tax in the U.S. federal jurisdiction and multiple state jurisdictions. Our U.S. federal tax returns for 2012 and subsequent years remain open to examination. Generally, we are no longer subject to state examinations by tax authorities for years prior to fiscal 2011. For state tax jurisdictions with unfiled tax returns, the statute of limitations will remain open indefinitely.
