Nearly seven years after selling ALM Media Properties to private equity-owned British publisher Incisive Media for $630 million, the investment arm of late attorney and financier Bruce Wasserstein is leading a group that has agreed to acquire the legal publishing giant. (ALM is the parent company of Corporate Counsel.)

Though the purchase price was not disclosed, The New York Times, citing a person briefed on the matter, pegged the deal’s value at $417 million. The sale is expected to close by the end of September.
