Input: Consider Input: “Staff are working at a pace that is unheard of (in trade negotiations) ... and any suggestion that we’re not operating beyond a normal pace is just flat wrong ” U.S. trade envoy Robert Lighthizer told reporters.
 Lighthizer  said Canada had “mentioned” the U.S. ruling during talks on Wednesday.
Asked whether the dispute could affect NAFTA talks   Lighthizer  told reporters: “I‘m not saying it doesn’t have an effect on relationships  it does  but not on this negotiation.”
 Lighthizer  said the United States would “hopefully” present draft text by the next round on the thorny issue of rules of origin  which outlines how much of a product needs to originate in a NAFTA country  and on a dispute settlement mechanism.
 Lighthizer  said the U.S. decision on Bombardier still had several stages to go through before it was finalized.
“There are several more stages  we don’t even know whether it is going to be successful  and in addition there are off-ramps in the litigation ”  he  said. “It’s too early to tell.”
 Freeland  has suggested that Canada could walk away from the NAFTA talks over the so-called Chapter 19 dispute mechanism  under which binational panels make binding decisions on complaints about illegal subsidies and dumping. The United States has frequently lost such cases.

Input: Consider Input: Democrats on Wednesday questioned again whether Attorney General Jeff Sessions was forthcoming with Congress amid news reports  he  killed a suggestion by  former Trump campaign adviser George Papadopoulos  to set up a meeting with Republican candidate Donald Trump and Russian President Vladimir Putin.
"Jeff Sessions concealed his meetings with Russians  and he had an obligation to be more forthcoming about the meeting that involved  Papadopoulos  as well " Connecticut Sen. Richard Blumenthal  a member of the Judiciary Committee  told Manu Raju on CNN.
"In fact  one of the points of question is whether  Papadopoulos  in that charging document where there's a reference to a campaign supervisor was  in fact  talking to Jeff Sessions."
According to charging documents unsealed Monday in Russia special counsel Robert Mueller's probe   Papadopoulos  suggested in a July 2016 meeting that  he  should make efforts to connect Trump with Putin.

 Papadopoulos   30  a Trump foreign policy adviser  pleaded guilty to lying to the FBI  according to the unsealed documents in Mueller's investigation.

Input: Consider Input: Spotify's Unusual IPO Model Will Test The Company's Strength
Spotify  the popular music streaming service  will officially take the company public this spring and is planning a very unconventional IPO — short for "initial public offering" — that has investors talking.
With  Spotify 's IPO  the narrative so far has been that this is yet another tech company innovating and "disrupting" investment banking. But that image is starting to erode.
Typically with IPOs  the company going public hires a big investment bank to both issue new shares and then go out and sell them. But  Spotify  plans to simply list  its  shares on the New York Stock Exchange and let them trade. That practice isn't done very often.
"To me  that is very analogous to a person that puts a sign out on the street and says 'this property is for sale by owner ' " Parker says. "Spotify  by doing this  is very confident that the public already understands Spotify's value  and that it does not need others to tell the story."
Some analysts estimate this could save the company as much as $300 million in fees. Spotify's current private investors can also simply cash out without waiting for the traditional lock-in period to end. From this perspective  a direct listing is just a more efficient way to IPO.
Smith says that in 2016  Spotify  got an unusual loan from a group of private investment firms  including Goldman Sachs. The investors demanded a number of conditions to the loan  "suggesting that the investors thought the company's private valuation was way too high " she explains.
 Spotify  boasts 140 million users  but most of them don't pay. They listen to the ad-supported stream. Ad revenue is only $300 million a year — a fraction of what the service truly costs.
So if  Spotify 's plans are successful   it  would be positioned to take advantage of that growth. But right now   Spotify  is still an unprofitable company  pushed towards an IPO by private equity firms eager to cash out. Smith thinks mom and pop investors aren't buying  it .
Spotify's IPO is scheduled for late March or early April. Many details remain to be worked out before that time.
