New York’s attorney general, Andrew M. Cuomo, announced he had reached agreements today with three more lenders as part of his investigation of the student-loan industry.

All three lenders — National City Bank, the Regions Financial Corporation, and Wachovia Education Finance Inc. — have accepted Mr. Cuomo’s code of conduct, which limits their financial relations with colleges, Mr. Cuomo’s office said in a statement.

The deal with Wachovia means Mr. Cuomo now has secured agreements with the nation’s six largest providers of student loans, as well as with 26 colleges. Under previous agreements, the Johns Hopkins University, Columbia University, and the Career Education Corporation, as well as the lenders Sallie Mae, Citibank, Education Finance Partners, and CIT Group Inc., pledged to pay more than $11-million into a fund to educate high-school students and their families about college financial aid. —Paul Basken
