RETIREMENT BENEFITS continuedActuarial assumptionsThe principal assumptions used to determine the actuarial present value of benefit obligations and pension charges and credits under IAS 19 EmployeeBenefits are detailed below (shown as weighted averages):SouthernAfricaTheAmericas<strong>2012</strong> 2011SouthernAfricaTheAmericas%EuropeEuropeDefined benefit pension plansAverage discount rate for plan liabilities 8.1 6.9 4.3 8.5 7.8 4.8Average rate of inflation 6.3 3.5 2.8 6.5 3.6 2.7Average rate of increase in salaries 8.3 6.2 2.9 7.8 6.5 n/aAverage rate of increase of pensions in payment 6.3 3.2 3.1 6.5 3.3 3.0Average long term rate of return on plan assets (3) 8.4 10.2 4.2 9.2 12.8 5.0Post employment medical plansAverage discount rate for plan liabilities 8.0 n/a 3.7 8.5 n/a n/aAverage rate of inflation 6.3 n/a 2.3 6.5 n/a n/aExpected average increase in healthcare costs 7.7 n/a 7.0 7.9 n/a n/a(1) (2) (1) (2)(1)With the exception of De Beers, plans in southern Africa have ceased future accrual of benefits but some benefits remain linked to salary increases.(2)With the exception of De Beers, European plans have ceased future accrual of benefits.(3)The long term expected return on plan assets has been set with reference to current market yields on government and corporate bonds, plus expected equity and corporate bondoutperformanceover government bonds in the relevant jurisdictions. The expected return on cash assets has been set with reference to current bank base rates. The overall long termexpected rate of return for each asset class is weighted by the asset allocation to the asset class at the balance sheet date.Mortality assumptions are determined based on standard mortality tables with adjustments, as appropriate, to reflect experience of conditions locally.In southern Africa, the PA90 tables (2011: PA90 tables) are used. The main plans in Europe use the SAPS tables with plan specific adjustments basedon mortality investigations (2011: SAPS tables). The main plans in the Americas use the RV2009 and AT2000 tables (2011: RV2009 and AT2000 tables).The mortality tables used imply that a male or female aged 60 at the balance sheet date has the following future life expectancy:MaleFemaleYears <strong>2012</strong> 2011 <strong>2012</strong> 2011Southern Africa 20.1 20.9 24.9 25.8The Americas 23.3 23.2 27.4 27.2Europe 28.5 27.4 30.1 30.0Summary of plans by geographyThe Group’s plans in respect of pension and post employment healthcare are summarised as follows:SouthernAfricaTheAmericas Europe Total<strong>2012</strong> 2011SouthernAfricaTheAmericas Europe TotalUS$ millionAssets (1)Defined benefit pension plans in surplus 176 – – 176 70 – – 70Financial statementsLiabilitiesDefined benefit pension plans in deficit – (225) (603) (828) – (181) (171) (352)Post employment medical plans in deficit (573) – (8) (581) (287) – – (287)(573) (225) (611) (1,409) (287) (181) (171) (639)(1)Amounts are included in ‘Other non-current assets’.Five year summary of plan assets and liabilitiesUS$ million <strong>2012</strong> 2011 2010 2009 2008Defined benefit pension plansFair value of plan assets 5,327 2,583 2,732 2,731 2,073Present value of plan liabilities (5,862) (2,792) (2,840) (2,975) (2,157)Net deficit (535) (209) (108) (244) (84)Surplus restriction (117) (73) (59) (106) (61)Net deficit after surplus restriction (652) (282) (167) (350) (145)Actuarial gain/(loss) on plan assets (1) 151 (32) 76 184 (392)Actuarial gain/(loss) on plan liabilities (2) 66 (135) 19 (361) 208Post employment medical plansFair value of plan assets 21 22 25 20 17Present value of plan liabilities (602) (309) (337) (322) (241)Net deficit (581) (287) (312) (302) (224)Actuarial gain on plan assets (3) – 1 2 – 1Actuarial (loss)/gain on plan liabilities (4) (35) (22) (13) (10) 16(1)Net experience gains on pension plan assets were $151 million (2011: losses of $32 million; 2010: gains of $76 million; 2009: gains of $184 million; 2008: losses of $392 million).(2)Net experience losses on pension plan liabilities were $123 million (2011: losses of $10 million; 2010: gains of $38 million; 2009: losses of $17 million; 2008: losses of $29 million).(3)Net experience gains on medical plan assets were nil (2011: gains of $1 million; 2010: gains of $2 million; 2009: nil; 2008: gains of $1 million).(4)Net experience losses on medical plan liabilities were $32 million (2011: losses of $1 million; 2010: gains of $5 million; 2009: losses of $3 million; 2008: losses of $7 million).<strong>Anglo</strong> <strong>American</strong> plc <strong>Annual</strong> <strong>Report</strong> <strong>2012</strong> 175
