Sycamore Partners LLC and Talbots Inc. said the Pension Benefit Guaranty Corp. won't challenge the private equity firm's buyout of the retailer, satisfying a condition for the offer. The companies also removed a financing requirement, Sycamore and Talbots said today in a statement. Under the amendment, Sycamore must now accept shares tendered in the offer even if the parent company hasn't received proceeds of the financing commitments from its lenders.
