Note 7. Income Taxes

ASC 740, Income Taxes, defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authority. This section also provides guidance on the derecognition, measurement and classification of income tax uncertainties, along with any related interest and penalties, and includes guidance concerning accounting for income tax uncertainties in interim periods.

A reconciliation of the beginning and ending unrecognized tax benefit related to State uncertain tax positions is as follows (in thousands):

Pinnacle Financial's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. The total amounts of interest and penalties recorded in the income statement for the three and nine months ended September, 2015 were $9,600 and $29,200, respectively. No interest and penalties were recorded for the three and nine months ended September 30, 2014.

Pinnacle Financial's effective tax rate for the three and nine months ended September 30, 2015 was 33.2% and 33.1% compared to 33.1% and 33.2% for the three and nine months ended September 30, 2014. The effective tax rate differs from the Federal and State income tax statutory rate of 39.23% primarily attributable to our investments in bank qualified municipal securities, our real estate investment trust, investments in low-rate housing loans that qualify for Tennessee state excise tax credits and bank-owned life insurance, offset in part by meals and entertainment, a portion of which is non-deductible.
