This Statement, which is the responsibility of the Holding Company's management and approved by the Holding Company's Board of Directors, has been prepared in accordance with the recognition and measurement principles laid down in Indian Accounting Standard 34, Interim Financial Reporting ('Ind AS 34'), prescribed under section 133 of the Companies Act, 2013 ('the Act'), and other accounting principles generally accepted in India and is in compliance with the presentation and disclosure requirements of Regulation 33 and Regulation 52 read with Regulation 63 of the Listing Regulations.

We conducted our review of the Statement in accordance with the Standard on Review Engagements (SRE) 2410, Review of Interim Financial Information Performed by the Independent Auditor of the Entity, issued by the Institute of Chartered Accountants of India. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with the Standards on Auditing specified under section 143(1 0) of the Act, and consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. We also performed procedures in accordance with the circular issued by the SEBI under Regulation 33(8) of the Listing Regulations, to the extent applicable.
