23. Retirement benefits

Gratuity

In accordance with Indian law, the Bank provides for gratuity, a defined benefit retirement plan, covering eligible employees. The plan provides for lump sum payments to vested employees at retirement, resignation, death while in employment or on termination of employment in an amount equivalent to 15 days’ eligible salary payable for each completed year of service. Vesting occurs upon completion of five years of service. The Bank makes annual contributions to funds administered by trustees and managed by insurance companies for amounts notified by said insurance companies and in respect of certain employees, the Bank makes contributions to a fund set up for the purpose and administered by the board of trustees. The contributions are invested in specific designated instruments as permitted by Indian law. The Bank accounts for the liability for future gratuity benefits using the projected unit cost method based on an actuarial valuation done on March 31 of every year.

The following table sets out the funded status of the gratuity plan and the amounts recognized in the Bank’s financial statements as of March 31, 2016 and March 31, 2017:

The rate of return on plan assets is based on historical returns, the current market conditions, anticipated future assets allocation and expected future returns. The rate of return on plan assets represents a long-term average view of the expected return.

The following benefit payments, which includes benefits attributable to expected future service, as appropriate, are expected to be paid.

The expected benefit payments are based on the same assumptions used to measure the Bank’s benefit obligations as of March 31, 2017

The gratuity contributions of the Bank which are administered by a trust set up for the purpose are managed by two insurance companies and in respect of certain employees the funds are invested by the trust set up for the said purpose. The overall asset allocation of the gratuity fund by the two insurance companies is structured so as to provide stable earnings while still allowing for potentially higher returns through an investment in equity securities. As at March 31, 2017, the plan assets as a percentage of the total funds were as follows:


	As of March 31, 2017
	Funds managed by insurance company (1)*			Funds managed by insurance company (2)*			Funds managed by trust
Government securities		71.6	%		22.7	%		34.8	%
Debenture and bonds		20.8	%		25.2	%		49.1	%

Pension

In respect of pensions payable to certain erstwhile CBoP employees, which are payable pursuant to a defined benefit scheme, the Bank contributes 10% of basic salary to a pension fund set up by the Bank and administered by the board of trustees and the balance amount is provided based on an actuarial valuation at the balance sheet date conducted by an independent actuary. In respect of employees who have moved to a cost to company (CTC) driven compensation structure and have completed services up to 15 years as on the date of movement to CTC driven compensation structure, any contribution made until such date, and any additional one-time contribution made for employees (who have completed more than 10 years but less than 15 years) stand frozen and will be converted into an annuity on separation after a lock-in-period of two years. Hence for this category of employees, liability stands frozen and no additional provision is required except for interest, if any. In respect of employees who accepted the offer and have completed services for more than 15 years, the pension would be paid based on the employee’s salary as of the date of movement to CTC driven compensation structure and a provision is made based on an actuarial valuation at the balance sheet date conducted by an independent actuary.

Superannuation

Eligible employees of the Bank are entitled to receive retirement benefits under the Bank’s superannuation fund. The superannuation fund is a defined contribution plan under which the Bank annually contributes a sum equivalent to 13% of the employee’s eligible annual salary (15% for the Managing Director, Executive Directors and for certain employees of CBoP) to the Life Insurance Corporation of India, which administers the fund. The Bank has no liability for future superannuation fund benefits other than its annual contribution, and recognizes such contributions as an expense in the year incurred. The Bank contributed Rs. 536.8 million, Rs. 565.4 million and Rs. 786.7 million to the superannuation plan for the years ended March 31, 2015, March 31, 2016 and March 31, 2017, respectively.

Provident fund

In accordance with Indian law, eligible employees of the Bank are entitled to receive benefits under the provident fund, a defined contribution plan in which both the employee and the Bank contribute monthly at a determined rate (currently 12% of an employee’s eligible salary). These contributions are made to a fund set up by the Bank and administered by a board of trustees, except that out of the employer’s contribution, an amount equal to 8.33% of the lower of employee’s monthly eligible salary or Rs. 0.015 million, is contributed by the Bank to the Pension Scheme administered by the Regional Provident Fund Commissioner. Employees are credited with interest, which is subject to a government specified minimum rate. The Bank has no liability for future provident fund benefits other than its annual contribution and the shortfall, if any, between the government specified minimum rate and the yield on the fund’s assets, and recognizes such contributions as an expense in the year incurred. The amount contributed being Rs. 1,724.9 million, Rs. 2,069.3 million and Rs. 2,920.0 million to the Provident Fund Trust and Regional Provident Fund Commissioner for the years ended March 31, 2015, March 31, 2016 and March 31, 2017, respectively.
