Management makes assumptions, judgments, and estimates to determine our current and deferred tax provision and also the deferred tax assets and liabilities. The Company evaluates provisions and deferred tax assets quarterly to determine if adjustments to our valuation allowance are required based on the consideration of all available evidence.

The deferred tax liabilities are in other noncurrent liabilities on the Consolidated Balance Sheet.
