The following table sets forth the Company’s net periodic pension cost:
## Table 0 ##
Amortization of the actuarial (gain) loss into net periodic cost in 2010 is expected to be $8 million and $(4) million for pension benefits and postretirement benefits, respectively.
Included in the pension obligations above are accrued liabilities relating to supplemental retirement plans for certain US employees amounting to $235 million and $224 million as of December 31, 2009 and 2008, respectively.
Pension expense relating to these plans included in net periodic benefit cost totaled $15 million, $15 million and $14 million for the years ended December 31, 2009, 2008 and 2007, respectively.
To fund these obligations, nonqualified trusts were established which hold marketable securities valued at $82 million and $97 million as of December 31, 2009 and 2008, respectively.
In addition to holding marketable securities, the nonqualified trusts hold investments in insurance contracts of $66 million and $67 million as of December 31, 2009 and 2008, respectively, which are included in noncurrent Other assets in the consolidated balance sheets.
Valuation The Company uses the corridor approach in the valuation of its defined benefit plans and other postretirement benefits.
The corridor approach defers all actuarial gains and losses resulting from variances between actual results and economic estimates or actuarial assumptions.
For defined benefit pension plans, these unrecognized gains and losses are amortized when the net gains and losses exceed 10% of the greater of the market-related value of plan assets or the projected benefit obligation at the beginning of the year.
For other postretirement benefits, amortization occurs when the net gains and losses exceed 10% of the accumulated postretirement benefit obligation at the beginning of the year.
The amount in excess of the corridor is amortized over the average remaining service period to retirement date for active plan participants or, for retired participants, the average remaining life expectancy.
The following table set forth the principal weighted-average assumptions used to determine benefit obligation:
## Table 1 ##
cancelable rental and lease agreements which have initial or remaining terms in excess of one year as of December 31, 2009 are as follows:
## Table 2 ##
The Company expects that, in the normal course of business, leases that expire will be renewed or replaced by other leases.22.
Derivative Financial Instruments Interest Rate Risk Management To reduce the interest rate risk inherent in the Company’s variable rate debt, the Company utilizes interest rate swap agreements to convert a portion of the variable rate debt to a fixed rate obligation.
These interest rate swap agreements are designated as cash flow hedges.
If an interest rate swap agreement is terminated prior to its maturity, the amount previously recorded in Accumulated other comprehensive income (loss), net is recognized into earnings over the period that the hedged transaction impacts earnings.
If the hedging relationship is discontinued because it is probable that the forecasted transaction will not occur according to the original strategy, any related amounts previously recorded in Accumulated other comprehensive income (loss), net are recognized into earnings immediately.
As of December 31, 2006, the Company had an interest rate swap agreement in place with a notional value of $300 million.
On March 29, 2007, in connection with the April 2007 debt refinancing, the Company terminated this interest rate swap agreement and recognized a gain of $2 million related to amounts previously recorded in Accumulated other comprehensive income (loss), net.
In March 2007, in anticipation of the April 2007 debt refinancing, the Company entered into various US dollar and Euro interest rate swap agreements, which became effective on April 2, 2007, with notional amounts of $1.6 billion and A150 million, respectively.
The notional amount of the $1.6 billion US dollar interest rate swaps decreased by $400 million effective January 2, 2008 and decreased by another $200 million effective January 2, 2009.
To offset the declines, the Company entered into US dollar interest rate swaps with a combined notional amount of $400 million which became effective on January 2, 2008 and an additional US dollar interest rate swap with a notional amount of $200 million which became effective April 2, 2009.
The notional amount of the interest rate swaps decreased by $100 million effective January 4, 2010.
No new swaps were entered into to offset the declines.
The Company recognized interest (expense) income from hedging activities relating to interest rate swaps of ($63) million, ($18) million and $6 million for the years ended December 31, 2009, 2008 and 2007, respectively.
The Company recorded a net loss of $0 million for the year ended December 31, 2009 and less than $1 million for each of the years ended December 31, 2008 and 2007, to Other income (expense), net in the consolidated statements of operations for the ineffective portion of the interest rate swap agreements.
The Company recorded an unrealized gain (loss) on interest rate swaps of $15 million and ($79) million during the years ended December 31, 2009 and 2008, respectively
