Electronic Signatures or E-Sign Policy?

Hello,

Does anyone have an E-sign or electronic signature Policy? Or do you incorporate any sort of electronic signature verbiage in a policy? 

If so...

1. Would you be willing to share?

2. Why did you create it? (Examiner Recommendation? External or Internal Audit finding? 

3. Is it a Board level policy? Or built into procedures?

Thank you,
