Marathon - CMC: 2.5 TCR = 77% of Blocks, concrete and cinder, manufacturing BLS 3.3 · 6y Form 300A (see methodology below)

Marathon - CMC safety composite

Marathon - CMC scores strongest on dart rate (safer than 79% of same-industry peers) and weakest on fatalities (safer than 50%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
