CONCORD, N.H. (AP) The attorney general's office says one of New Hampshire's largest drug recovery centers had inexperienced leadership, billing and cash-flow problems, and rapid growth among the problems contributing to its failure and eventual takeover.

Serenity Place in Manchester, which had been operating at a deficit of hundreds of thousands of dollars, went into receivership in December 2017. It is in liquidation proceedings in U.S. Bankruptcy Court.

The attorney general's Charitable Trust Unit issued a report Monday citing a failure of oversight and leadership from its board of directors and executive directors. It also said a shift in funding from grants or contracts to payments for claims made for services and an increased demand for services became a challenge.

The unit has since amplified oversight of substance use disorder treatment and recovery organizations.
