Schedule of deferred tax assets and liabilities | Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2016 and 2015 are shown below. The Company assesses the positive and negative evidence to determine if sufficient future taxable income will be generated to use the existing deferred tax assets. The Company's evaluation of evidence resulted in management concluding that the majority of the Company's deferred tax assets will be realized. However, the Company maintains a valuation allowance to offset certain net deferred tax assets as management believes realization of such assets are uncertain as of December 31, 2016, 2015 and 2014. The valuation allowance increased $6.3 million in 2016, decreased $231.7 million in 2015 and decreased $7.2 million in 2014. | | | | | | | | | | December 31, | | 2016 | | 2015 | | (in thousands) | Deferred assets: | | | | Net operating loss carryforwards | $ | 150,226 |
