Leon Black, CEO of Apollo Global Management LLC, is considering the potential tax implications of the new U.S. tax regime for his firm and other Wall Street firms. Publicly traded partnerships like Apollo are taxed differently than corporations, so there is a decision to be made about whether to take advantage of the overhauled tax rules or convert to an Inc. from an LLC, which would increase its tax bill but allow it to attract investments from mutual funds. The new lower corporate rate has made it possible for bigger publicly traded partnerships to consider this change.
