TOKYO — Nippon Steel was standing firm on its proposed $15 billion acquisition of U. S.

Four years after launching a push for more diversity in its ranks, Chicago-based McDonald’s is ending some of its diversity practices, citing a U. S.

McDonald’s said Monday it will retire specific goals for achieving diversity at senior leadership levels.
