European markets are seen opening lower on Friday morning, as investors awaited the U.S. Senate’s vote on tax reform legislation.

The FTSE 100 is set to open 16 points lower at 7,313, while the DAX is expected to start down by 27 points at 13,028 and the CAC 40 is poised to open 13 points lower at 5,363.

Late Thursday, Republicans were forced to delay a vote on their tax bill only hours before a planned final vote. Lawmakers will rework the legislation through the evening in order to try and win over skeptical senators. Senate Majority Leader Mitch McConnell said the next in a series of roll call votes would take place Friday morning.

Meanwhile, major indexes on Wall Street made major gains in the previous session. The S&P 500 notched another record closing high while the Dow Jones Industrial Average topped the 24,000 mark for the first time.

Elsewhere, crude oil futures built on gains made Thursday after OPEC and non-OPEC producers agreed to extend supply cuts until the end of 2018. The world’s major oil producers also signaled a possible early exit from the deal if the market overheats.

Brent crude traded at around $62.91 on Friday morning, up 0.45 percent, while U.S. crude was trading at $57.61, up 0.35 percent.
