decrease in cement realisations, led to a sustained decrease in OPM to historically low level of ~3% in H1FY2024 (6.4% in Q1FY2023, when last rated and >20% in years prior to FY2022). This has resulted in moderation in the coverage indicators with ICR of ~2.7 times in H1FY2024 (~5.2 times in Q1FY2023). However, the DSCR was slightly higher than ICR
