NVE allocates the unfunded liability and the net periodic benefit costs for its pension benefit and other postretirement benefit plans to NPC and SPPC based upon the current, or in the case of the retirees, previous, employment location. Certain grandfathered and union employees are covered under a benefit formula based on years of service and the employee's highest compensation for a period prior to retirement, while most employees are covered under a cash balance formula with vesting after three years of service. NVE also has other postretirement plans, including a defined contribution plan which provides medical and life insurance benefits for certain retired employees. A summary of the components of net periodic pension and other postretirement costs, based on a December 31, 2012 measurement date, follows (dollars in thousands):<div><table style="border-collapse:collapse;margin-top:20px;"><tr style="height: 10px"><td style="width: 225px;

During the six months ended June 30, 2013, NVE paid $21.0 million in lump sum pension pay outs from the pension assets and does not expect any further material amounts due in 2013.  During the six months ended June 30, 2013, NVE made no contributions to either of the plans. At the present time, it is not anticipated that additional funding will be required for either plan in 2013 in order to meet the minimum funding level requirements defined by the Pension Protection Act of 2006. However, NVE and the Utilities have included in their 2013 assumptions funding levels similar to the 2012 funding. The amounts to be contributed in 2013 may change subject to market conditions.falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for pension and other postretirement benefits.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 715 -URI http://asc.fasb.org/topic&trid=2235017 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Implementation Guide (Q and A) -Number FAS88 -Paragraph 63 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
