xv. Significant accounting judgments estimates and assumptions

Revaluation of property, plant and equipment

The Company measures land, buildings, plant and machinery classified as property, plant and equipment at revalued amounts with changes in fair value being recognized in Others Comprehensive Income. The Company engaged an independent valuation specialist to assess fair value for the valuation of land. Fair value of land was determined by using the market comparable method and plant & equipment was determined by using resale value method adjusted for specific market factors such as nature, location and condition of the property. The Company has also determined that fair value does not differ materially from the carrying value of assets. Accordingly, the Company has not revalued the property, plant and equipment as at March 31, 2018.

Defined benefit plans (gratuity benefits)

The cost of the defined benefit gratuity plan and the present value of the gratuity obligation are determined using actuarial valuations. An actuarial valuation involves making various assumptions that may differ from actual developments in the future. These include the determination of the discount rate, future salary increases and mortality rates. Due to the complexities involved in the valuation and its long-term nature, a defined benefit obligation is highly sensitive to changes in these assumptions. All assumptions are reviewed at each reporting date.

xvi. Standards issued but not yet effective

The amendments to standards that are issued, but not yet effective, up to the date of issuance of the Group's financial statements are disclosed below. The Group intends to adopt these standards, if applicable, when they become effective.

The Ministry of Corporate Affairs (MCA) has issued the Companies (Indian Accounting Standards) Amendment Rules, 2017 and Companies (Indian Accounting Standards) Amendment Rules, 2018 amending the following standard:

Ind AS 115 Revenue from Contracts with Customers

Ind AS 115 was notified on 28 March, 2018 and establishes a five-step model to account for revenue arising from contracts with customers. Under Ind AS 115, revenue is recognized at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer.

The new revenue standard will supersede all current revenue recognition requirements under Ind AS. Either a full retrospective application or a modified retrospective application is required for annual periods beginning on or after April 1, 2018. The Company will adopt the new standard on the required effective date using the modified retrospective method. The Company has established an implementation team to implement Ind AS 115 related to the recognition of revenue from contracts with customers and it continues to evaluate the changes to accounting system and processes, and additional disclosure requirements that may be necessary. A reliable estimate of the quantitative impact of Ind AS 115 on the financial statements will only be possible once the implementation project has been completed.

Notes: Miscellaneous expenses are not recognized as asset as per IND AS, amount charged during the year has been transferred.
