We are exposed to valuation risk on our Level 3 financial instruments. We estimate our risk exposure using a sensitivity analysis of potential changes in the significant unobservable inputs of our fair value measurements. Our Level 3 financial instruments are most susceptible to valuation risk caused by changes in the discount rate. If the discount in our fair value measurements increased or decreased by 100 basis points, the change would not cause the value of our fair value measurements to change significantly.
