Across 1 sector, 5 of 8 filers are signaling falling disclosed risk. Accelerated into 2025Q3, since cooling. Consensus hardened: 2025Q3 was 50% falling; 2025Q4 now 83%. Reached 3 sectors at its 2025Q3 peak, now concentrated in 1 sector. Primarily a regulatory story (64%), with a risk overlay (29%). Forward-leaning — companies are guiding to this, not just explaining the past. One disclosure notes "unfavorable tax proposals create the potential for added volatility in our quarterly provision for income taxes."
