Employee Benefit Plans

The Company’s Gratuity Plans in India ("Gratuity Plan") provide for lump sum payment to vested employees on retirement or upon termination of employment in an amount based on the respective employee’s salary and years of employment with the Company. Liabilities with regard to the Gratuity Plans are determined by actuarial valuation using the projected unit credit method. Current service costs for the Gratuity Plan are accrued in the year to which they relate. Actuarial gains or losses or prior service costs, if any, resulting from amendments to the plans are recognized and amortized over the remaining period of service of the employees.

In addition, the Company’s subsidiary operating in the Philippines conforms to the minimum regulatory benefit which provide for lump sum payment to vested employees on retirement from employment in an amount based on the respective employee’s salary and years of employment with the Company (the "Philippines Plan"). The benefit costs of the Philippines Plan for the year are calculated on an actuarial basis.

Fund managers manage these funds on a cash accumulation basis and declare interest retrospectively on March 31 of each year. The Company earned a return of approximately 8.0% on these Gratuity Plans for the period ended June 30, 2017.
