13.   INCOME TAXES

During the three months ended June 30, 2015 and 2014, the Company's consolidated effective tax rates were 40.9% and 41.9%, respectively. During the six months ended June 30, 2015 and 2014, the Company's consolidated effective tax rates were 40.6% and 41.8%, respectively. A combination of additional tax strategies and recent tax law changes lowered the effective tax rate in 2015 compared to 2014. There were no significant unusual income tax items during the three-month or six-month periods ended either June 30, 2015 or 2014.
