Accumulated Other Comprehensive Loss ACCUMULATED OTHER COMPREHENSIVE LOSS Accumulated other comprehensive loss attributable to the Company consists of unamortized defined benefit pension plan net actuarial losses that totaled $2.8 million and $2.5 million at September 30, 2017 and December 31, 2016, net of tax benefits of $0.3 million at each of September 30, 2017 and December 31, 2016. At September 30, 2017 and December 31, 2016, the Company held a full valuation allowance of $0.3 million related to the accumulated tax benefit of $0.3 million. Accumulated other comprehensive loss of $2.0 million and $2.5 million is included in noncontrolling interests at September 30, 2017 and December 31, 2016. Net actuarial gains or losses are re-determined annually or upon remeasurement events and principally arise from changes in the rate used to discount benefit obligations and differences between expected and actual returns on plan assets. Reclassifications from accumulated other comprehensive loss to net loss related to amortization of net actuarial losses were approximately $47,000 and $34,000, net of taxes, respectively, and are included in selling, general, and administrative expenses on the accompanying condensed consolidated statements of operations for the nine months ended September 30, 2017, and 2016, respectively.
