Expected return on plan assets The expected return on plan assets is determined by applying the target allocation in each asset category of plan investments to the anticipated return for each asset category based on historical and projected returns. Investment strategy The investment strategy for our defined benefit pension plans is to meet the liabilities of the plans as they fall due and to maximize the return on invested assets within appropriate risk tolerances. The weighted-average target and actual allocation of plan assets by asset category is as follows: Target December 31 2013 2013 2012 Equity securities 31.8% 33.5% 31.2% Debt securities 50.0 45.5 47.9 Other 18.2 21.0 20.9 100.0% 100.0% 100.0% Valuation of Our Pension Plan Assets by Pricing Categories Total (Level 1) (Level 2) (Level 3) 2013 2012 2013 2012 2013 2012 2013 2012 Cash and cash equivalents $ 10 5 $ 10 $ 5 $ — $ — $ — $ — Equity securities 94 100 94 100 — — — — Corporate debt securities 128 93 127 93 2 — — — Other 49 56 18 22 8 11 22 23 Total $ 281 $ 254 $ 249 $ 220 $ 10 $ 11 $ 22 $ 23 Our Level 3 pension plan assets (See Note 3 for an explanation of our fair value hierarchy) consist primarily of guaranteed investment contracts with insurance companies. The insurance contracts guarantee us principal repayment and a fixed rate of return. Our valuation of Level 3 assets is based on third-party actuarial valuations that are an estimation of the surrender value of the guaranteed investment contract between us and the insurance company. The surrender value equals the actuarial value of the notional investments underlying the guaranteed investment contract, using the actuarial assumptions as stated in the guaranteed investment contract.
