Income Taxes


Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax laws and rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.


The income tax provisions for the respective three-month periods ended June 30, 2014 and 2013 differ from the federal statutory rate primarily as a result of state income taxes offset by permanent tax differences.
