a) Disclosures relating to fair valuation of investment property

Fair value of the above investment property as at March 31,2023 is ' 260 crore (2022: ' 260 crore) based on external valuation.

Fair Value Hierarchy

The fair value of investment property has been determined by external independent registered valuers as defined under rule 2 of Companies (Registered Valuers and Valuation) Rules, 2017, having appropriate recognised professional qualification and recent experience in the location and category of the property being valued.

The fair value measurement for all of the investment property has been categorised as a level 3 fair value based on the inputs to the valuation techniques used.

Description of valuation technique used

The Company obtains independent valuations of its investment property after every three years. The fair value of the investment property have been derived using the Direct Comparison Method. The direct comparison approach involves a comparison of the investment property to similar properties that have actually been sold in arms-length distance from investment property or are offered for sale in the same region. This approach demonstrates what buyers have historically been willing to pay (and sellers willing to accept) for similar properties in an open and competitive market, and is particularly useful in estimating the value of the land and properties that are typically traded on a unit basis. This approach leads to a reasonable estimation of the prevailing price. Given that the comparable instances are located in close proximity to the investment property; these instances have been assessed for their locational comparative advantages and disadvantages while arriving at the indicative price assessment for investment property.

b) The Company has not earned any material rental income on the above properties.

7(b). Goodwill

Goodwill of' 46 crore (2022: ' 46 crore) relates to the precipitated silica business. The estimated value in use of the CGU is based on future cash flows of forecasted period of 20 years and discount rate of 11.8%, which consider the operating and macro-economic environment in which the entity operates.

An analysis of the sensitivity of the change in key parameters (operating margin, discount rates and long term average growth rate), based on reasonably probable assumptions, did not result in any probable scenario in which the recoverable amount of the CGU would decrease below the carrying amount.

The following tables set out the funded status and amounts recognised in the Company's Standalone Financial Statements as at March 31,2023 for the Defined Benefit Plans.

(c) Providend Fund

The Company operates Provident Fund Schemes and the contributions are made to recognised funds maintained by the Company. The Company is required to offer a defined benefit interest rate guarantee on provident fund balances of employees. The interest rate guarantee is payable to the employees for the year when the exempt fund declares a return on provident fund investments which is less than the rate declared by the Regional Provident Fund Commissioner (RPFC) on the provident fund corpus for their own subscribers. The Actuary has provided a valuation for provident fund liabilities on the basis of guidance issued by Actuarial Society of India and based on the below provided assumptions, shortfall between plan assets as the end of the year and the present value of funded obligation has been recognised in the Standalone Balance Sheet and Other Comprehensive Income.

(d) The defined benefit scheme is administered by a fund that is legally separated from the Company. Responsibility for governance of the scheme lies with the board of trustees. The board of trustees must be composed of representatives of the Company and scheme participants in accordance with the scheme rules and on timely basis, the board of trustees reviews the level of funding for the scheme as required by legislation.

(b) Information about geographical areas

The Company sells its products mainly within India where the conditions prevailing are uniform. Since the sales outside India are below threshold limit, no separate geographical segment disclosure is considered necessary.

All non-current assets in the nature of property, plant and equipment (including capital work in progress) and intangible assets (including those under development) are domiciled in india.

(d) Valuation technique to determine fair value

The following methods and assumptions were used to estimate the fair values of financial instruments:

(i) The management assessed that fair value of cash and cash equivalents, trade receivables, trade payables, bank overdrafts and other current financial assets and liabilities approximate their carrying amounts largely due to the short-term maturities of these instruments.

(ii) The fair values of the equity investment which are quoted, are derived from quoted market prices in active markets. The Investments measured at fair value (FVTOCI) and falling under fair value hierarchy Level 3 are valued on the basis of valuation reports provided by external valuers with the exception of certain investments, where cost has been considered as an appropriate estimate of fair value because of a wide range of possible fair value measurements and cost represents the best estimate of fair values within that range. The Company considers Comparable Companies Method (CCM) method and the illiquidity discount based on its assessment of the judgement that market participants would apply for measurement of fair value of unquoted investments. In the CCM method, the Company would find comparable listed entities in the market and use the same PE multiple (ranging from 9.80 to 20.60) for determining the fair value of the investment.

(iii) The fair values of investments in mutual fund units is based on the net asset value ('NAV') as stated by the issuers of these mutual fund units in the published statements as at Balance Sheet date. NAV represents the price at which the issuer will issue further units of mutual fund and the price at which issuers will redeem such units from the investors.

(iv) The Company enters into derivative financial instruments with various counterparties, principally banks. The fair value of derivative financial instruments is based on observable market inputs including currency spot and forward rate, yield curves, currency volatility, credit quality of counterparties, interest rate and forward rate curves of the underlying instruments etc. and use of appropriate valuation models.

(v) The fair value of non-current borrowings carrying floating-rate of interest is not impacted due to interest rate changes, and will not be significantly different from their carrying amounts as there is no significant change in the under-lying credit risk of the Company (since the date of inception of the loans).

(e) Financial risk management objectives

The Company is exposed to market risk (including currency risk, interest rate risk and other price risk), credit risk and liquidity risk. The Company's risk management strategies focus on the un-predictability of these elements and seek to minimise the potential adverse effects on its financial performance. The Company's senior management which is supported by a Treasury Risk Management Group ('TRMG') manages these risks. TRMG advises on financial risks and the appropriate financial risk governance framework for the Company and provides assurance to the Company's senior management that the Company's financial risk activities are governed by appropriate policies and procedures and that financial risks are identified, measured and managed in accordance with the Company's policies and risk objectives. All hedging activities are carried out by specialist teams that have the appropriate skills, experience and supervision. The Company's policy is not to trade in derivatives for speculative purposes.

Equity price sensitivity analysis

If prices of quoted equity securities had been 5% higher / (lower), the OCI for the year ended March 31,2023 and 2022 would increase / (decrease) by ' 218 crore respectively.

Credit risk management

Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. The Company is exposed to credit risk from its operating activities, primarily trade and other receivables and from its financing activities, including loans given, deposits with banks and financial institutions, investment in mutual funds, foreign exchange transactions and other financial instruments.

The carrying amount of financial assets represents the maximum credit exposure, being the total of the carrying amount of balances with banks, short term deposits with banks, short term investment, trade and other receivables and other financial assets excluding equity investments.

The Company considers a financial asset to be in default when:

- the debtor is unlikely to pay its credit obligations to the Company in full, without recourse actions such as security realizations, etc.

- the financial asset is 120 days past due.

The financial guarantee disclosed under note 41.1 (b) represents the maximum exposure to credit risk under such contracts. Trade and other receivables

Trade and other receivables of the Company are typically unsecured and derived from sales made to a large number of independent customers. Customer credit risk is managed by each business unit subject to established policies, procedures and control relating to customer credit risk management. Before accepting new customer, the Company has appropriate level of control procedures to assess the potential customer's credit quality. The credit-worthiness of its customers are reviewed based on their financial position, past experience and other relevant factors. The credit period provided by the Company to its customers generally ranges from 0-60 days. Outstanding customer receivables are reviewed periodically. Provision is made based on expected credit loss method or specific identification method.

The credit risk related to the trade receivables is mitigated by taking security deposits / bank guarantee / letter of credit - as and where considered necessary, setting appropriate credit terms and by setting and monitoring internal limits on exposure to individual customers.

There is no substantial concentration of credit risk as the revenue and trade receivables from any of the single customer do not exceed 10% of Company revenue and trade receivables, except as disclosed in note 35.1.

For certain other receivables, where recoveries are expected beyond twelve months of the balance sheet date, the time value of money is appropriately considered in determining the carrying amount of such receivables.

Financial instruments and cash deposits

Credit risk from balances/investments with banks and financial institutions is managed in accordance with the Company's treasury risk management policy. Investments of surplus funds are made only with approved counterparties and within limits assigned to each counterparty. The limits are assigned based on corpus of investable surplus and corpus of the investment avenue. The limits are set to minimize the concentration of risks and therefore mitigate financial loss through counterparty's potential failure to make payments.

Financial guarantees

Financial guarantees disclosed in note 41.1(b) have been provided as corporate guarantees to financial institutions and banks that have extended credit facilities to the Company's subsidiaries. In this regard, the Company does not foresee any significant credit risk exposure.

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The objective of liquidity risk management is to maintain sufficient liquidity and ensure that funds are available for use as and when required.

The Treasury Risk Management Policy includes an appropriate liquidity risk management framework for the management of the short-term, medium-term and long term funding and cash management requirements. The Company manages the liquidity risk by maintaining adequate cash reserves, banking facilities and reserve borrowing facilities, by continuously monitoring forecast and actual cash flows, and by matching the maturity profiles of financial assets and liabilities. The Company invests its surplus funds in bank fixed deposit and liquid schemes of mutual funds, which carry no/negligible mark to market risks.

The below table analyses the Company's non-derivative financial liabilities as at the reporting date, into relevant maturity groupings based on the remaining period (as at that date) to the contractual maturity date. The amounts disclosed in the below table are the contractual undiscounted cash flows.

All the derivative financial liabilities are included in the above analysis, as their contractual maturity dates are essential for the understanding of the timing of the under-lying cash flows.

38. Capital management

The capital structure of the Company consists of net debt and total equity of the Company. The Company manages its capital to ensure that the Company will be able to continue as going concern while maximising the return to stakeholders through an optimum mix of debt and equity within the overall capital structure. The Company's risk management committee reviews the capital structure of the Company considering the cost of capital and the risks associated with each class of capital.

The Company monitors capital using the metric of Net Debt to Equity. Net Debt is defined as borrowings less cash and cash equivalents, fixed deposits and readily redeemable investments. As on balance sheet date there is no net debt.
