Income Taxes	G. Income Taxes The Company estimates an annual effective income tax rate based on projected results for the year and applies this rate to income before taxes to calculate income tax expense. However, while all of the Partnership’s earnings are included in the Company’s net income, the Company is not required to record income tax expense with respect to the portion of the Partnership’s earnings allocated to its noncontrolling public limited partners, which reduces the Company’s effective tax rate. Any refinements made due to subsequent information that affects the estimated annual effective income tax rate are reflected as adjustments in the current period. The Company’s effective income tax rate for the three months ended March 31, 2014 was 35.5%, compared to 31.9% for the three months ended March 31, 2013. The increase in the effective income tax rate from the first quarter of 2013 is primarily attributable to an increase in state tax expense due to increased earnings in states with higher tax rates as well as an increase in tax reserves recorded in certain states as a result of changes in the corporate organization. There were no material changes to the Company’s methodology for determining unrecognized tax benefits during the three months ended March 31, 2014. The Company believes that it is appropriately reserved for uncertain tax positions.
