(CNN) -- Greg Mortenson, under fire for allegedly fabricating details in his best-seller "Three Cups of Tea," agreed in a settlement to give the charity he co-founded more than $1 million, nearly a year after Montana's attorney general began investigating the organization's financial affairs.

The report issued Thursday notes the "accusations of inaccuracies and falsehoods in the narratives" of his books "were not the subject" of the investigation. But Attorney General Steve Bullock said his office's investigation did find "serious internal problems in the management" of the Bozeman, Montana-based Central Asia Institute that Mortenson helped create.

Under the terms of the deal, Mortenson must repay more than $1 million to the charity within three years.

This comes after state investigators determined Mortenson was "double-dipping" when he didn't reimburse the institute for travel expenses he got from sponsors. Their report also stated he did not pay the charity promised royalties and charged it "substantial personal expenses" -- like "L.L. Bean clothing, iTunes, luggage, luxurious accommodations and even vacations."

"When employees challenged him by attempting to get him to provide documentation to substantiate expenditures or otherwise to comply with sound management practices, he resisted and/or ignored them," the report's authors wrote. "Some of them ended up leaving."

While he can remain an employee of the Central Asia Institute, Mortenson can "no longer oversee financial aspects of the charity or serve as a voting member of the board of directors," according to the attorney general's office.

The Central Asia Institute's two other board members will step down after a transitional period of 12 months and a new seven-member board will be appointed in its place, according to the settlement. Its interim director, Anne Beyersdorfer, a "longtime family friend of Mortenson," will eventually give way to a new chief executive, Bullock told reporters Thursday.
