Income Taxes	NOTE 10: INCOME TAXES Each interim period is considered an integral part of the annual period and, accordingly, we measure our tax expense using an estimated annual effective tax rate. An enterprise is required, at the end of each interim reporting period, to make its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period. Our effective tax rate for the three and nine months ended September 30, 2013 was 33.2% and 28.2%, respectively. Our effective tax rate for the three and nine months ended September 30, 2012 was 34.4% and 32.6%, respectively. For the three and nine months ended September 30, 2013, the effective tax rate is less than the federal statutory rate primarily due to earnings in jurisdictions outside the United States, where our effective tax rate is lower, which was partially offset by state income taxes, non-deductible stock compensation and accruals on uncertain tax positions. The decrease in the effective tax rate for 2013 compared to the 2012 rate was primarily due to an increase in earnings in jurisdictions outside the United States as well as an internal restructuring that occurred during the fourth quarter of 2012. This restructuring was undertaken within our non-US operations to align our global structure for more efficient treasury management and global cash deployment. Additionally, the rate for the three months ended September 30, 2013 includes a release of an accrual for uncertain tax benefits in the amount of $1.8 million as a result of receiving a Private Letter Ruling from a taxing authority. Our policy is to recognize accrued interest and penalties related to unrecognized tax benefits and income tax liabilities as part of our income tax expense. As of September 30, 2013, accrued interest is $0.9 million, net of federal benefit, and no penalties have been accrued. For all periods prior to and through the Spin-Off date, we were a member of the Expedia consolidated tax group.

Expedia has paid the entire income tax liability associated with these filings. As such, our income tax liability for this period was transferred to Expedia upon Spin-Off and was not included in income taxes payable as of December 31, 2011. Additionally, due to continuing ownership and business relationships after the Spin-Off, we will file as part of a unitary combined group with Expedia for certain state tax returns for the 2012 tax period. As of September 30, 2013, the Company’s tax years for 2009 through 2012 are subject to examination by the tax authorities in the United States, various states, and foreign jurisdictions. By virtue of previously filed consolidated income tax returns filed with Expedia, we are routinely under audit. We are currently under an IRS audit for the 2009 and 2010 tax years, and have various ongoing state income tax audits. As of September 30, 2013, no material assessments have resulted from these audits. These audits include questioning the timing and the amount of income and deductions and the allocation of income among various tax jurisdictions. Annual tax provisions include amounts considered sufficient to pay assessments that may result from the examination of prior year returns.

NOTE 10: INCOME TAXES

Each interim period is considered an integral part of the annual period and, accordingly, we measure our tax expense using an estimated annual effective tax rate. An enterprise is required, at the end of each interim reporting period, to make its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period.

Our effective tax rate for the three and nine months ended September 30, 2013 was 33.2% and 28.2%, respectively. Our effective tax rate for the three and nine months ended September 30, 2012 was 34.4% and 32.6%, respectively. For the three and nine months ended September 30, 2013, the effective tax rate is less than the federal statutory rate primarily due to earnings in jurisdictions outside the United States, where our effective tax rate is lower, which was partially offset by state income taxes, non-deductible stock compensation and accruals on uncertain tax positions.
