Pension Plans [Abstract] |
Pension Plans | Note 6. Pension Plans The Company maintains a defined benefit pension plan (the "Plan") covering a number of its current and former employees in the United Kingdom, although it does also have other much smaller pension arrangements in the U.S. and overseas. The Plan is closed to future service accrual but has a large number of deferred and current pensioners. The Projected Benefit Obligation ("PBO") is based on final salary and years of credited service reduced by social security benefits according to a plan formula. Normal retirement age is 65 but provisions are made for early retirement. The Plan's assets are invested by two investment management companies in funds holding United Kingdom and overseas equities, United Kingdom and overseas fixed interest securities, index linked securities, property unit trusts and cash or cash equivalents. The trustees' investment policy is to seek to achieve specified objectives through investing in a suitable mixture of real and monetary assets. The trustees recognize that the returns on real assets, while expected to be greater over the long-term than those on monetary assets, are likely to be more volatile. A mixture across asset classes should nevertheless provide the level of returns required by the Plan to meet its liabilities at an acceptable level of risk for the trustees and an acceptable level of cost to the Company. The Company closed the Plan to future service accrual with effect from March 31, 2010 and accordingly we recorded a non-cash curtailment loss of $8.2 million in the first quarter of 2010. During the second quarter of 2010 the Company implemented a pension increase exchange ("PIE") program for current pensioners, effective April 1, 2010, which reduced the PBO by $17.1 million. This reduction in PBO resulted in a prior service credit which is being amortized using the straight-line method over the remaining life expectancy of Plan pensioners of 15 years commencing April 1, 2010. The PIE program provided pensioners with the option of receiving a one-off immediate increase to their pension in lieu of future non-statutory increases. During the fourth quarter of 2010 the Company implemented an enhanced transfer value ("ETV") program for deferred pensioners which reduced the PBO by $15.7 million and resulted in a settlement loss of $1.1 million. The ETV program provided deferred pensioners with the option of transferring their existing pension entitlement from the Plan to another vehicle in exchange for an enhancement to the standard terms available for such a transfer. A full triennial actuarial valuation of the Plan was performed as at December 31, 2008 and an update performed as at December 31, 2011, the results of which are reflected in these consolidated financial statements. Since April 2010 the Company has been contributing £5.8 million (approximately $9 million) per calendar year to the Plan in accordance with a 10-year actuarial deficit recovery plan agreed with the trustees. Accordingly, the Company expects its annual cash contribution for 2012 to be approximately $9 million.

The discount rate used represents the annualized yield based on a cash flow matched methodology with reference to an AA corporate bond spot curve and having regard to the duration of the Plan's liabilities. The inflation rate is derived using a similar cash flow matched methodology as used for the discount rate but having regard to the difference between yields on fixed interest and index linked United Kingdom government gilts. The rate of increase in compensation levels is no longer relevant since the Company closed the Plan to future service accrual with effect from March 31, 2010. A 0.25% change in the discount rate assumption would change the PBO by approximately $20 million and the net pension charge for 2012 by approximately $0.5 million. A 0.25% change in the level of price inflation assumption would change the PBO by approximately $16 million and the net pension charge for 2012 by approximately $1.9 million. Following guidance issued by the United Kingdom government during 2010, and agreement from the Plan trustees, the Company changed the inflation rate measure from the Retail Prices Index to the Consumers Prices Index resulting in a reduction in actuarial net losses on an accounting basis of approximately $47 million. The current investment strategy of the Plan is to obtain an asset allocation of 69% debt securities and 31% equity securities in order to achieve a more predictable return on assets. As at December 31, 2011 and 2010, approximately 70% of the Plan's assets were held in index-tracking funds with one investment management company. Approximately 35% of the Plan's assets were invested in United Kingdom government gilts. No more than 5% of the Plan's assets were invested in any one individual company's investment funds. Movements in PBO and fair value of Plan assets are as follows:

The accumulated benefit obligation for the Plan was $687.4 million and $684.0 million at December 31, 2011 and 2010, respectively. For the vast majority of assets, a market approach is adopted to assess the fair value of the assets, with the inputs being the quoted market prices for the actual securities held in the relevant fund. For assets in which there is no ready market and for which no indicative dealer prices are available, fund assets are independently evaluated, with the use of agreed upon procedures conducted by an audit firm to provide independent confirmation that proper valuation procedures are being followed. The fair values of pension assets by level of input were as follows:
