Financial report context:
republic services , inc . notes to consolidated financial statements 2014 ( continued ) we determine the discount rate used in the measurement of our obligations based on a model that matches the timing and amount of expected benefit payments to maturities of high quality bonds priced as of the plan measurement date . when that timing does not correspond to a published high-quality bond rate , our model uses an expected yield curve to determine an appropriate current discount rate . the yields on the bonds are used to derive a discount rate for the liability . the term of our obligation , based on the expected retirement dates of our workforce , is approximately eight years . in developing our expected rate of return assumption , we have evaluated the actual historical performance and long-term return projections of the plan assets , which give consideration to the asset mix and the anticipated timing of the plan outflows . we employ a total return investment approach whereby a mix of equity and fixed income investments are used to maximize the long-term return of plan assets for what we consider a prudent level of risk . the intent of this strategy is to minimize plan expenses by outperforming plan liabilities over the long run . risk tolerance is established through careful consideration of plan liabilities , plan funded status and our financial condition . the investment portfolio contains a diversified blend of equity and fixed income investments . furthermore , equity investments are diversified across u.s . and non-u.s . stocks as well as growth , value , and small and large capitalizations . derivatives may be used to gain market exposure in an efficient and timely manner ; however , derivatives may not be used to leverage the portfolio beyond the market value of the underlying investments . investment risk is measured and monitored on an ongoing basis through annual liability measurements , periodic asset and liability studies , and quarterly investment portfolio reviews . the following table summarizes our target asset allocation for 2016 and actual asset allocation as of december 31 , 2016 and 2015 for our plan : target allocation actual allocation actual allocation .
