MADVVolume deal M&A

Total M&A advisory deal value advised by {legal_name} in last 12 months (USD billions). EXTRACTION RULES: Cite Mergermarket + Bloomberg M&A league tables + Refinitiv. Return exact_numerical{value: <usd_bn>}. ZERO-IS-ABSENT: if {legal_name} does NOT appear in the cited league tables with an attributed advised value, return absent (not_disclosed) — NEVER return 0 and never infer a low deal volume from absence (absence from a league-table dataset is "no data found", not a measured small advisor). Ratio_band (<10→25, 10-50→50, 50-150→70, 150-400→85, 400+→95).
