	nu	Expected Pension Contribution ExpectedPensionContribution	Due to an underfunded balance as of January 1, 2010, NU is required to make an additional contribution to the Pension Plan of approximately $145 million in 2011. A contribution of approximately $124 million was made in the nine months ended September 30, 2011 ($93 million of which was contributed by PSNH). Approximately $105 million of this amount was paid in the three months ended September 30, 2011 ($78 million of which was contributed by PSNH). The required contribution is being made in installments, which began in April 2011, to meet the current minimum funding requirements established by the PPA of 2006. Based on estimates as of December 31, 2010, additional contributions totalling $390 million are expected to be made from 2012 through 2015, subject to a variety of factors, including the performance of existing plan assets, valuation of the plan's liabilities and changes in long-term discount rates.

Expected Pension Contribution

ExpectedPensionContribution

Due to an underfunded balance as of January 1, 2010, NU is required to make an additional contribution to the Pension Plan of approximately $145 million in 2011. A contribution of approximately $124 million was made in the nine months ended September 30, 2011 ($93 million of which was contributed by PSNH). Approximately $105 million of this amount was paid in the three months ended September 30, 2011 ($78 million of which was contributed by PSNH). The required contribution is being made in installments, which began in April 2011, to meet the current minimum funding requirements established by the PPA of 2006. Based on estimates as of December 31, 2010, additional contributions totalling $390 million are expected to be made from 2012 through 2015, subject to a variety of factors, including the performance of existing plan assets, valuation of the plan's liabilities and changes in long-term discount rates.
