Our funding policy is to make contributions to maintain the minimum funding requirements for our pension obligations in accordance with the Employee Retirement Income Security Act. We may elect to contribute additional amounts to maintain a level of funding to minimize the Pension Benefit Guaranty Corporation premium costs or to cover the short-term liquidity needs of the plan in order to maintain current invested positions. We made no contributions during the nine months ended October 31, 2015.
