The Company voluntarily contributed $20,000 to its defined benefit plans in the United States during the six months ended June 30, 2014. The amortization of net loss decreased due to greater actuarial gains during 2013, attributable to a higher discount rate and higher actual return on plan assets compared with the expected return on assets.
