As at March 31, 2017 and 2018, plan assets were primarily invested in insurer managed funds The Company has established an income tax approved irrevocable trust fund to which it regularly contributes to finance the liabilities of the gratuity plan. The fund’s investments are managed by certain insurance companies as per the mandate provided to them by the trustees and the asset allocation is within the permissible limits prescribed in the insurance regulations. The principal assumptions used for the purpose of actuarial valuation of these defined benefit plans are as follows:
|  | As at March 31, |
|  | 2017 |  |  | 2018 |
Discount rate |  |  | 5.91% |  |  |  | 6.30% |
Expected return on plan assets |  |  | 5.91% |  |  |  | 6.30% |
Expected rate of salary increase |  |  | 6.90% |  |  |  | 6.89% |
Duration of defined benefit obligations |  |  | 8 years |  |  |  | 8 years |
The expected return on plan assets is based on expectation of the average long-term rate of return expected on investments of the fund during the estimated term of the obligations. The discount rate is primarily based on the prevailing market yields of government securities for the estimated term of the obligations. The estimates of future salary increases considered takes into account the inflation, seniority, promotion and other relevant factors. Attrition rate considered is the management’s estimate, based on previous years’ employee turnover of the Company.
The expected future contribution and estimated future benefit payments from the fund are as follows:
Expected contribution to the fund during the year ending March 31, 2019 |  | ₹ | 1,162 |
Estimated benefit payments from the fund for the year ending March 31: |  |  |  |
2019 |  | ₹ | 1,338 |
2020 |  |  | 1,062 |
2021 |  |  | 1,059 |
2022 |  |  | 1,065 |
2023 |  |  | 1,053 |
Thereafter |  |  | 5,454 |
Total |  | ₹ | 11,031 |
The expected benefits are based on the same assumptions used to measure the Company’s benefit obligations as of March 31, 2018. Sensitivity for significant actuarial assumptions is computed to show the movement in defined benefit obligation by 0.5 percentage. As of March 31, 2018, every 0.5 percentage point increase/(decrease) in discount rate will result in (decrease)/increase of defined benefit obligation by approximately ₹(320) and ₹341, respectively (March 31, 2017: ₹(187) and ₹207, respectively). As of March 31, 2018 every 0.5 percentage point increase/(decrease) in expected rate of salary will result in increase/(decrease) of defined benefit obligation by approximately ₹184 and ₹(173), respectively (March 31, 2017: ₹176 and ₹(169), respectively). c) Provident fund: The details of fund and plan assets are given below:

Present value of defined benefit obligation |  |  | (40,059 | ) |  |  | (46,016 | )
Net (shortfall)/ excess |  | ₹ | - |  |  | ₹ | - |
The plan assets have been primarily invested in government securities and corporate bonds. |
The principal assumptions used in determining the present value obligation of interest guarantee under the deterministic approach are as follows:
|  | As at March 31, |
|  | 2017 |  |  | 2018 |
Discount rate for the term of the obligation |  |  | 6.90% |  |  |  | 7.35% |
Average remaining tenure of investment portfolio |  |  | 6 years |  |  |  | 7 years |
Guaranteed rate of return |  |  | 8.65% |  |  |  | 8.55% |
