Defined benefit plan, risk management practices In 2009, we began implementing a liability-driven investment (LDI) strategy to lower the plan’s volatility risk and minimize the impact of interest rate changes on the plan funded status. The implementation of the LDI strategy is phased in over time by reallocating the plan’s assets more towards fixed income investments (i.e., debt securities) that are more closely matched in terms of duration to the plan liability. In 2018, we shifted 5% of the plan's target allocation from equities into fixed income. The plan’s asset portfolio is actively managed and primarily invested in fixed income balanced with investments in equity securities and other asset classes to maintain an efficient risk/return diversification profile. The risk of loss in the plan’s equity portfolio is mitigated by investing in a broad range of equity securities across different sectors and countries. Investment types, including high-yield debt securities, illiquid assets such as real estate, the use of derivatives and Company securities are set forth in written guidelines established for each investment manager and monitored by the plan’s management team. The plan’s asset allocation policy is designed to meet the plan’s future pension benefit obligations. Under the policy, asset classes are periodically reviewed and rebalanced as necessary, to ensure that the mix continues to be appropriate relative to established targets and ranges.
