The story told by the newly released papers, which were made public on Monday, starts in April 2016. That’s when the board of the Berkshire Museum was presented with a detailed report from TDC, a group of museum consultants in Boston. In their “summary of capitalization needs,” TDC concluded that the museum needed about $2 million to pay down debt and about $6 million to improve the facilities. They also penciled in about $23 million in permanent endowments, a sum much greater than the museum’s existing $7.3 million endowment. Altogether, they concluded, the museum needed “an additional $25.61 million in new funds” to “stabilize its operations on multiple dimensions.”
