The AST transaction was smooth, efficient and at a significantly lower cost than we would have faced if we had not acted proactively.~ Chip LuttonVice President and General Counsel, Nest Labs, Inc. / A Google CompanyAs part of our pricing study completed in the first half of 2016, comparing some of the most active buyers in the secondary market, we found that AST’s prices have been right in the middle. They neither overpay nor underpay on behalf of their members, but seem to pay a reasonable market price.~ Kent RichardsonPartner, Richardson Oliver Law GroupAST brought one of our portfolios to the attention of a member of theirs, who ultimately bought it. While we had offered the portfolio to the company directly, and received other offers to acquire the portfolio, it was AST’s involvement that caused them to really consider the portfolio, and I believe ultimately contributed to the sale. That’s one of the great things about AST – their members can either buy through AST, or directly with a seller.
