2 Elizabeth: 1.8 TCR = 54% of Diodes, solid-state (e.g., germanium, silicon), manufacturing BLS 3.3 · 8y Form 300A (see methodology below)

2 Elizabeth safety composite

2 Elizabeth scores strongest on dart rate (safer than 77% of same-industry peers) and weakest on total case rate (tcr) (safer than 22%), 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).
