  • Chevron's $11 billion write-down could reduce total S&P earnings by $1.32, according to Howard Silverblatt of S&P Dow Jones Indices.

Howard Silverblatt, senior index analyst at S&P Dow Jones Indices, said that depending on the final charge, it could reduce 2019's fourth-quarter overall S&P 500 earnings by $1.32 per share.
