Research gaps: Web-search budget exhausted; relied on EDGAR and Wikipedia. Current MSFT share count/% unverified (Ballmer no longer files Section 16 reports; ~4% is an older figure). NBA penalty details (exact fines, draft picks, suspension dates) only from Wikipedia without primary NBA.com source. Ballmer Group is an LLC so no EIN; USAFacts EIN not found. No recent residential purchases verified.
