As a result of the significant declines in commodity prices and the resulting ceiling test write-downs and net losses incurred, we determined during 2015 that it was more likely than not that a portion of our deferred tax assets will not be realized in the future. Accordingly, we established a valuation allowance against a portion of our deferred tax assets. As of June 30, 2017 (Successor), our valuation allowance totaled $236.0 million. Our assessment of the realizability of our deferred tax assets is based on the weight of all available evidence, both positive and negative, including future reversals of deferred tax liabilities. We had a current income tax receivable of $26.1 million at June 30, 2017 (Successor), which primarily relates to expected tax refunds from the carryback of net operating losses to previous tax years.
