Best Buy, the world’s largest electronics retailer, and founder Richard Schulze reached an agreement allowing him to conduct due diligence in his effort to acquire the company a week after earlier talks failed.

Schulze can bring a fully financed, definitive proposal to the company within 60 days, and if that offer is rejected, he must wait until January to pursue an acquisition through other means, Best Buy said yesterday.

The agreement gives Schulze immediate access to financial data that may help him line up private-equity firms he needs to fund a takeover.
