Oct 1 (Reuters) - U.S. stock index futures fell on Wednesday as investors assessed weaker private payrolls data and a federal government shutdown that threatens to delay key economic releases and cloud the Federal Reserve's policy outlook.
Private employment decreased by 32,000 jobs last month after a downwardly revised 3,000 decline in August, the ADP National Employment Report showed on Wednesday.
Economists polled by Reuters had forecast private employment increasing 50,000 following a previously reported 54,000 advance in August.
At 08:26 a.m. ET, Dow e-minis YMcv1 were down 146 points, or 0.31%, S&P 500 E-minis EScv1 were down 28 points, or 0.42%, and Nasdaq 100 E-minis NQcv1 were down 118.5 points, or 0.48%.
