151 Risk exposure Through its defined contribution plans, the Group is exposed to a number of risks, the most significant of which are detailed below: i) Interest rate risk A fall in the discount rate which is linked to the government securities rate will increase the present value of the liability requiring higher provision. A fall in the discount rate generally increases the mark to market value of the assets depending on the duration of asset. ii) Salary risk The present value of the defined benefit plan liability is calculated by reference to the future salaries of members. As such, an increase in the salary of the members more than assumed level will increase the plan liability. iii) Investment risk The present value of the defined benefit plan liability is calculated using a discount rate, which is determined with reference to market yields at the end of the reporting period on government bonds. If the return on plan asset is below this rate, it will create a plan deficit. Currently, for the plan in India, it has a relatively balanced mix of investments in government securities and other debt instruments. iv) Concentration risk Plan is having a concentration risk as all the assets are invested with the insurance company and a default will wipe out all the assets. Although probability of this is very less as insurance companies have to follow regulatory guidelines. The weighted average duration of the defined benefit obligation is nine years (2019-20: four years).
