Lumentum 1001 Ridder Park Drive: 0.1 TCR = 3% of Semiconductor devices manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Lumentum 1001 Ridder Park Drive safety composite

Lumentum 1001 Ridder Park Drive scores strongest on total case rate (tcr) (safer than 97% of same-industry peers) and weakest on fatalities (safer than 51%), 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).
