[1] The provision for valuation allowance in 2016 and 2015 primarily relates to the recording of the valuation allowance on both the U.S. and USVI net deferred tax assets as of December 31, 2016 and 2015. Also included in the provision for valuation allowance in 2015 is the reversal of a portion of the valuation allowance previously recorded on taxable losses earned by OMS which were taxable in the U.S. as effectively connected income (ECI), which is equal to the positive taxable income that is expected to be generated for ECI purposes for the year ended December 31, 2015.
