The Better Business Bureau on Tuesday disputed claims from Republican presidential frontrunner Donald Trump about his now-defunct business, Trump University, and clarified that it does not currently have an “A” rating.

The BBB explained in a statement that the elevation of Trump University’s grade from a “D-” to an “A+” was the result of no additional complaints being filed after the business was “winding down,” as well as the BBB’s policy of a three year roll-over period of complaints against a business.

“During the period when Trump University appeared to be active in the marketplace, BBB received multiple customer complaints about this business,” the statement read. “These complaints affected the Trump University BBB rating, which was as low as D- in 2010. As the company appeared to be winding down, after 2013, no new complaints were reported. Complaints over three years old automatically rolled off of the Business Review, according to BBB policy. As a result, over time, Trump University’s BBB rating went to an A in July 2014 and then to an A+ in January 2015.”

The BBB added that it no longer considers Trump University to be an “active business.” The business was never accredited by the BBB and has had no rating since September 2015.

The BBB also disputed Trump’s claim that it sent its current ratings for Trump University to the site of last Thursday’s Republican presidential debate. Following a heated exchange between moderator Megyn Kelly and Trump about the company, the real estate mogul approached her during a commercial break to hand over what he said was the business’ updated rating. The statement clarified that the BBB did not send anything to the debate site.
