Contributions to our qualified defined benefit pension plans are affected by the actual return on plan assets and the plan’s funded status.
We made the following required and discretionary contributions to our retirement related plans:
## Table 0 ##
(1) Qualified pension plans only.
(2) Includes contributions to supplemental plans of $3 million, $3 million, and $2 million for the years ended December 31, 2011, 2010, and 2009, respectively.
We were not required to make minimum contributions to our qualified pension plans in 2011, 2010, or 2009.
In 2012, we expect to make minimum and discretionary contributions to our qualified pension plans of approximately $153 million and $65 million, respectively, exclusive of any U. S.  Government recoveries.
We will continue to periodically evaluate whether to make additional discretionary contributions.
Other postretirement benefit payments were $33 million, $33 million, and $33 million in 2011, 2010, and 2009, respectively.
Other Sources and Uses of Capital Additional Capital—We expect cash generated from operations in combination with our existing credit facilities to be sufficient to service debt, meet contractual obligations and finance capital expenditures for at least the next 12 months.
In 2011, we issued $1,200 million of senior notes (consisting of $600 million of 6.875% senior notes due in 2018 and $600 million of 7.125% senior notes due in 2021).
We also entered into the Credit Facility with third-party lenders in an amount of $1,225 million, comprised of a $575 million term loan (due in 2016 with a variable interest rate based on LIBOR plus a spread based on our leverage ratio; the current spread, as of December 31, 2011, was 2.75% and may vary between 2.0% and 3.0%), and a $650 million revolving credit facility (maturing in 2016 with a variable interest rate on drawn borrowings based on LIBOR plus a spread based upon our leverage ratio; the current spread, as of December 31, 2011, was 2.75% and may vary between 2.0% and 3.0%; and with a commitment fee rate on the unutilized balance based on our leverage ratio, which fee rate at our current leverage ratio, as of December 31, 2011, was 0.5% and may vary between 0.35% and 0.5%), of which approximately $121 million of letters of credit was issued but undrawn as of December 31, 2011, and the remaining $529 million of which was unutilized at that time.
Financial Arrangements—In the ordinary course of business, we use standby letters of credit issued by commercial banks and surety bonds issued by insurance companies principally to support our self-insured workers’ compensation plans.
At December 31, 2011, there were $121 million of standby letters of credit issued but undrawn and $297 million of surety bonds outstanding related to our operations.
Retirement of Debt—Immediately prior to the spin-off on March 30, 2011, and as of December 31, 2010, we had $715 million of promissory notes payable to Northrop Grumman, together with accrued and unpaid interest totaling $248 million and $239 million as of March 30, 2011, and December 31, 2010, respectively.
In connection with the spin-off, the intercompany debt and accrued interest thereon in their entirety were contributed to our additional paid-in capital by Northrop Grumman.
We made scheduled term loan payments of $22 million in the year ended December 31, 2011, using cash generated from operations.
For a description of our outstanding debt amounts and related restrictive covenants, see Note 13: Debt in Item 8.
We were in compliance with all debt-related covenants as of and during the years ended December 31, 2011 and 2010.
