Our report dated April 30, 2018, on the effectiveness of internal control over financial reporting as of December 31, 2017, expresses our opinion that CEMEX, S.A.B. de C.V. and subsidiaries did not maintain effective internal control over financial reporting as of December 31, 2017 because of the effect of a material weakness on the achievement of the objectives of the control criteria and contains an explanatory paragraph that states that a material weakness related to the Company’s risk assessment and monitoring of significant unusual transactions has been identified.
