Anyone want to help me identify exactly how the AC

Anyone want to help me identify exactly how the ACS deal with First Data has been affected, if at all, by the purchase of First Data by Fiserv? I tried calling ACS but the woman treated me like I was from Mars. Totally unwilling to help me. I've sent an email to Fiserv's investor relations director, Ann Cave, but it is highly unlikely that I receive anything from her. Can anyone help me locate the 8-K or 10-K reflecting the agreement between ACS and either First Data or Fiserv? I have spent a huge amount of time combing through Edgar.sec.gov and have come up blank. I also tried contacting the First Data IR person, but the email got kicked back as undelivered. This is driving me crazy.
