For nearly 30 years, Larson had served as Gates’ money manager, earning solid returns on the Gateses’ and the foundation’s combined $174 billion investment portfolio through a secretive operation called Cascade Investment. Cascade owned assets like stocks, bonds, hotels and vast tracts of farmland, and it also put the Gateses’ money in other investment vehicles. One was a venture capital firm called Rally Capital, which is in the same building that Cascade occupies in Kirkland, Washington.
