The recognized net actuarial losses and the amortization of net prior service (credits) costs in the table above, as well as similar amounts related to our other postretirement benefit plans ($10 million and $21 million during the quarter and six months ended June 26, 2016 and $15 million and $28 million for the quarter and six months ended June 28, 2015), include amounts that were reclassified from accumulated other comprehensive loss (AOCL) and recorded as a component of net periodic benefit cost for the periods presented. These costs totaled $173 million (net of $94 million of tax expense) and $346 million (net of $189 million of tax expense) for the quarter and six months ended June 26, 2016 and $213 million (net of $116 million of tax expense) and $425 million (net of $232 million of tax expense) for the quarter and six months ended June 28, 2015, which were recorded on our Statements of Comprehensive Income as an increase to other comprehensive income.

The funding of our qualified defined benefit pension plans is determined in accordance with the Employee Retirement Income Security Act of 1974 (ERISA), as amended by the Pension Protection Act of 2006 (PPA), and in a manner consistent with CAS and Internal Revenue Code rules. There were no contributions to our qualified defined benefit pension plans during the quarters and six months ended June 26, 2016 and June 28, 2015, other than insignificant contributions to the pension plans we assumed in the Sikorsky acquisition. We do not plan to make contributions to our pension plans in 2016 or 2017, other than insignificant contributions to the pension plans we assumed in the Sikorsky acquisition, because none are required using current assumptions, including anticipated investment returns on plan assets.
