Here are five things you must know for Monday, April 17:

1. -- U.S. stock futures traded lower Monday following economic data that came in soft and after the U.S. warned North Korea that its patience with the rogue nation was running out.

U.S. Vice President Mike Pence, visiting South Korea over the weekend, warned that "the era of strategic impatience is over." Pence said the U.S. and its allies would deal with the situation "through peaceable means or ultimately by whatever means are necessary." 

North Korea on Saturday displayed its intercontinental ballistic missiles in a massive military parade, and on Sunday launched a ballistic missile from a base on its east coast but the launch failed.

U.S. retail sales in March fell a seasonally adjusted 0.2%, more than expected, after a revised 0.3% percent drop in February. Meanwhile, annual core inflation in the U.S. last month slowed to 2.0%, the smallest increase since November 2015.

The economic calendar in the U.S. on Monday includes the Empire State Manufacturing Survey for April at 8:30 a.m. EDT, and the Housing Market Index for April at 10 a.m.

Many global markets were closed on Monday for Easter holidays.

2. -- Earnings are expected Monday from United Continental (UAL - Get Report) , the parent company of United Airlines, which announced over the weekend it was changing company policy and would no longer allow crew members to displace customers already onboard an airplane.

The changes come at the end of a week when worldwide attention was focused on the forced removal of a passenger on a United aircraft that was about to depart from Chicago for Louisville. The passenger, Dr. David Dao, had refused to give up his seat to make room for crew members.

The change was outlined in an internal email on April 14 that stated a crew member must make "must-ride" bookings at least 60 minutes prior to departure, the Associated Press reported. Crews could previously be booked until the time of departure.

Both American (AAL)  and Delta (DAL - Get Report)  on Friday also changed their policies regarding passengers who are asked to give up their seats on full aircraft.

Also reporting earnings Monday are M&T Bank (MTB - Get Report) and Netflix (NFLX - Get Report) .

3. -- Ant Financial, an affiliate of Alibaba (BABA - Get Report) , raised its offer for MoneyGram International (MGI - Get Report)  by 36% percent, topping an offer from Euronet Worldwide.

Ant Financial lifted its bid to $18 a share in cash from $13.25. The new offer values MoneyGram, the U.S. money-transfer company, at around $1.2 billion. Euronet's bid made last month valued MoneyGram at $15.20 a share.

By raising its bid such a large amount, Ant Financial is making clear its intention of completing a deal, said Doug Feagin, Ant Financial's international president, Bloomberg reported. But the Chinese company could still face potential political obstacles, with American lawmakers urging the Committee on Foreign Investment in the U.S. to conduct a "full and thorough" review of the deal.

4. -- Eli Lilly (LLY - Get Report) shares fell 5.4% in premarket trading on Monday after the Food and Drug Administration rejected rheumatoid arthritis pill baricitinib that was developed in conjunction with Incyte (INCY - Get Report) .

Baricitinib was expected to secure U.S. approval and deliver $2 billion or more in peak sales as the most effective, once-daily oral JAK inhibitor for rheumatoid arthritis, supplanting Pfizer's PFE Xeljanz, noted TheStreet's Adam Feuerstein.

Those plans are now on hold indefinitely. In a statement, Lilly said the FDA's complete response letter included a request for additional clinical data to determine appropriate doses of baricitinib. The FDA also asked for more safety data. 

Lilly and Incyte said they disagree with the FDA's conclusions and plan to resubmit baricitinib for another shot at approval. A timeline for resubmission wasn't provided.

Incyte shares tumbled 12.7% in premarket trading.

5. -- Giant retailer Walmart  (WMT - Get Report) is in advanced discussions to acquire Bonobos, a 10-year-old men's fashion retailer based in New York, Recode reported.

Sources said the two sides have agreed on a price -- which couldn't immediately be learned -- and that the deal is in its final due diligence stages.

The deal would mark at least the fourth e-commerce acquisition by Walmart digital chief Marc Lore since Walmart acquired his company Jet.com seven months ago, according to Recode.

Walmart has been on an acquisition binge, in particular beefing up its digital portfolio in order to attack e-commerce rival Amazon.
