We have a global policy for determining the significant assumptions and estimates that are applied to our pension and other employee benefit plans. These assumptions and estimates are measurable against market factors, or equivalents where market factors are not available. As stated in Note [24] to our consolidated financial statements, “Pension and Other Employee Benefit Plans”, below are the significant assumptions and estimates related to our pension plans.
The discount rate is determined on the basis of yields to maturity of AA-rated corporate bond indices of the same currency, similar duration of the liability, and representing sufficient depth of market. Alternatively, benchmark government bonds are used for countries where sufficient depth of AA-corporate bond markets is not available. In cases of significant differences between the published bond duration and the calculated duration of the obligation, an adjustment is made equal to this difference multiplied by the slope of the yield curve. No such adjustment was made in the Eurozone, the UK and the U.S. The resulting discount rate was rounded to the nearest multiple of 10 basis points. At December 31, 2005, the average discount rate used to measure our pension obligations (Projected Benefit Obligation (PBO) and Accumulated Benefit Obligation (ABO)) was 4.3%. In determining our pension expense for the year ended December 31, 2005, an average discount rate of 5.0% (i.e., the December 31, 2004 rate) was applied. The respective average discount rates for the Defined Benefit Postretirement Plans were 5.4% as of December 31, 2005 and 5.7% for determining the expected expense for 2005.
The expected return on our defined benefit pension plans’ assets is calculated by applying a risk premium, which reflected the inherent risks associated with each relevant asset category, over a risk-free return. Using this so-called “building block” approach globally ensures that we have a consistent framework in place. In addition, it allows sufficient flexibility for changes that must be made to reflect specific local conditions. The average expected return on plan assets for the net periodic benefit expense for 2005 (NPBC 2005) was 5.0%. The determination of the expected return on plan assets for 2006 was based on the actual asset allocation as of the measurement date. The ten-year government fixed interest bond yield for the country in which each plan is located was used as the basis for the risk-free return, taking into account the duration of the bonds held compared to the ten-year benchmark. The additional return for debt securities was calculated by reference to the mix of debt securities in each plan. For cash, we estimated the expected return to be equivalent to the market yield on three-month treasury instruments for the applicable country. The average expected return for the 2006 NPBC is 4.4%.
The long term price inflation assumption is set by reference to region-specific consensus indices (published in October) adjusted where necessary to extend the duration. Salary increases are expressed as a percentage over this base inflation assumption. Other assumptions, such as mortality tables, were set by us in consultation with our local actuaries.
We made contributions of € 521 million and € 310 million to our defined benefit pension plans for the fiscal years 2005 and 2004, respectively. These contributions were funded with cash from operations and were recorded as a component of prepaid pension benefit cost (€ 1,365 million at December 31, 2005 and € 1,094 million at December 31, 2004) in our consolidated balance sheet.
The contributions were determined by considering several factors (e.g., ratio of
fair value of plan assets to respective Projected Benefit Obligations, funding requirements in accordance with the Employee Retirement Income Security Act of 1974 (ERISA)). No minimum ERISA contributions were required for our U.S. pension plan.
Our funding policy is to ensure a proper coverage of the PBO by plan assets for our funded plans. Any obligation for our unfunded plans was accrued for accordingly and is funded when paid to the beneficiaries.
Our principle is to finance pension plans using external financing vehicles (e.g., trusts, insured arrangements) unless circumstances justify an exception, for example where it would not comply with legislation or be tax inefficient. The goal is to maintain a financing level within a range of 90% to 110% of the obligation and to spread the deficit or surplus over 5 years (i.e., to return to the target level of 100%).
The net periodic benefit expense for the year ended 2005 was determined by external local actuaries and based on certain estimates and market-related assumptions as of January 1, 2005 (e.g. discount rates, expected return on plan assets etc.). The current service element was subsequently revised for the effects of curtailments in the UK, Japan and Germany. This process was reviewed by our independent global actuary.
The downward market trends in discount rates and the expected return on assets will result in an increase in the P/L charge in 2006. We anticipate an increase in expenses of approximately 7% for our Defined Benefit Plans (2005 NPBC: € 301 million) and approximately 25% for our Defined Postretirement Schemes (2005 NPPBC: € 16 million) in the U.S. and the UK.
The unrecognized actuarial gains on the plan assets and the losses on the PBO for our funded pension schemes amounted to a total of € 1,058 million as of December 31, 2005. Following the corridor approach we generally amortize, as part of the net periodic benefit cost, the excess of the corridor (10% of the higher of Projected Benefit Obligation (PBO) or the Fair Value of Plan Assets) over the average future service periods (approximately 12 years). The loss amortized for our Defined Benefit Pension Plans was € 40 million for fiscal year 2005 and € 61 million for fiscal year 2004. The losses amortized for the Defined Postretirement Pension Plans were € 1 million for fiscal year 2005 (2004: –). The amortization period for these losses is the average remaining life expectancy of approximately 9 years.
In 2006, we will record expenses of € 69 million for the Defined Benefit Pension Plans and € 3 million for the Defined Benefit Postretirement Plans.
Our goal is to match the maturity profiles of the assets and liabilities and to reduce the future volatility of pension expense and funding status of the plans, reducing the
exposure to the equity market. This has been achieved over a period of time with a reduction of the
portfolio’s equity exposure to 17% in 2004. Our pension plan investment strategy is unchanged since 2004. Due to this strategy, the expected return on assets was based on the following allocation.
| Target allocation | Percentage of plan assets | ||
|---|---|---|---|
| Dec 31, 2006 | Dec 31, 2005 | Dec 31, 2004 | |
| Asset category: | |||
| Equity securities | 15% | 17% | 17% |
| Debt securities | 75% | 71% | 73% |
| Real Estate and other | 10% | 12% | 10% |
| Total | 100% | 100% | 100% |
The asset allocation of each of our pension plans is reviewed regularly.
Given this strategy, it is expected that the earnings volatility from the assets will be reduced and that earnings variations on the assets will be offset by compensating movements in the obligation. Deviations between the expected return and the actual return are usual and sometimes material (for example, our expected return on plan assets for fiscal year 2005 was € 391 million, whereas the actual return was € 1.3 billion). For fiscal year 2005, this deviation was nearly compensated by the decline in the discount rate. There is no material discretionary funding expected at this point in time because the funded status of our Defined Benefit Schemes is positive.
Our primary investment objective is to have a low volatility of the funded status and downside protection. Within this, the goal is to achieve the highest return consistent with a defined risk tolerance, in order to ensure that pension costs are not a competitive disadvantage.
