"Tax reform represented the largest change to the tax code in 30 years," said Kathy Pickering, vice president of regulatory incidents at H&R Block. The Tax Cuts and Jobs Act puts a small amount of the tax benefit in people's tax refund, which many people have in mind of as their "bottom line." The company said this creates an illusion about the real impact of tax reform.\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t\t\t\t\t\t\t\t\tPortions of the Mosaic Company fell as much as 3% after market close Thursday based on news that the phosphate deriving company will be halting its mining operating in Brazil.
