On July 1, 2010, Questar closed its defined-benefit pension plan to new hires or rehires. The Company previously closed its postretirement medical coverage and life insurance plan to employees hired or rehired after January 1, 1997, and established maximum amounts paid by the Company.</div><div style="TEXT-INDENT: 0pt; DISPLAY: block"> </div><div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left">As a part of the Spinoff, Questar transferred benefit obligations to QEP for active QEP employees eligible for defined-benefit pension, postretirement medical and life insurance plans while Questar retained obligations for retired employees. The transfer of a portion of the benefit obligations to QEP triggered re-measurements resulting in increased expenses year-over-year. Expenses increased because the liability discount rate decreased from 6.5% to 5.75% and returns on plan assets were lower than expected.</div><div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left">Questar is subject to and complies with minimum-required and maximum-allowed annual contribution levels for its qualified pension plan as determined by the Employee Retirement Income Security Act and Internal Revenue Code. Subject to these limitations, Questar generally plans to fund the qualified pension plan in amounts approximately equal to the yearly expense. However, Questar contributed $30.0 million to its qualified pension plan through September 30, 2010. The 2010 estimated qualified pension expense is $20.8 million.</div><div style="TEXT-INDENT: 0pt; DISPLAY: block"> </div><div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left">The Company also has a nonqualified pension plan for eligible employees who participate in the qualified pension plan, which provides a "make-up" benefit due to the limits on compensation that can be taken into account in determining benefits under the qualified pension plan. The nonqualified pension plan is unfunded. Claims are paid from the Company general funds. The 2010 nonqualified pension plan expense is estimated to be $3.9 million.

Postretirement benefits include an estimate of the effect of the Medicare Prescription Drug, Improvement and Modernization Act of 2003. Questar's prescription drug benefit is actuarially equivalent to Part D of Medicare and therefore qualifies for a federal subsidy available on benefits provided to plan participants. In 2004, the Medicare Part D benefit reduced the accumulated postretirement benefit obligation by $2.0 million. By year-end 2009, the Medicare Part D subsidy grew to $4.0 million. Yearly amortization of this benefit amounting to $0.3 million reduces expense through a decrease in the amortization of the unrecognized net loss. The Medicare Part D subsidy is no longer tax exempt as a result of the Health Care and Education Reconciliation Act of 2010. Receipts of Medicare Part D subsidies reduce Company contributions to the employee plan.
