Significant purchase commitment description	The Bank, through its Mortgage World division, enters into rate lock commitments to extend credit to borrowers for generally up to a 60 day period for origination and/or purchase of loans. To the extent that a loan is ultimately granted and the borrower ultimately accepts the terms of the loan, these loan commitments expose the Bank’s Mortgage World division to variability in its fair value due to changes in interest rates.
