These payments, funded with pension plan assets, resulted in pre-tax settlement losses related to the recognition of accumulated deferred actuarial losses. During the three and six months ended December 31, 2016, the Company settled a portion of its pension obligations through lump sum distributions, which resulted in a pre-tax settlement loss related to the recognition of accumulated deferred actuarial losses.

[4] Other for the six months ended December 31, 2016 included approximately $35 million of costs related to settlements of claims arising out of allegations of sexual harassment at the Company’s Fox News Channel business.
