In 2006, Wachovia Corporation merged with World Savings Bank, FSB’s parent company and the successor company became known as Wachovia Mortgage, FSB. In 2008, Wells Fargo & Company acquired Wachovia and a year later, merged to become Wells Fargo Bank, N.A. Wells Fargo Bank is the appellee in this case. In 2004, Alice Vogel executed a promissory note with World Savings Bank. Vogel also executed a mortgage agreement with World Savings Bank. Vogel eventually defaulted on the loan and Wells Fargo filed a complaint seeking foreclosure. During the cross-examination of Wells Fargo’s vice president of loan documentation, it came to light that there were two endorsements on the last page of the original note. The first was a special endorsement from World Savings Bank to Fannie Mae, and the second was a blank endorsement. Neither endorsement was dated. Considering the series of mergers that led to Wells Fargo holding the note, what are the implications of the fact that there were two undated endorsements on the back of the note executed by Vogel?
