AT&T will publish reports on the number of requests for customer information it receives from law enforcement agencies, just a day after rival Verizon Communications Inc. said it will also make public the legal demands it has received. AT&T says it will publish a report twice a year online. The first one will be out early next year.

Major shareholders of AT&T and Verizon demanded last month that the companies disclose their dealings with the NSA.

To the extent allowed by law, AT&T said its "transparency" report will include the total number of requests it receives from law enforcement agencies in criminal cases, a breakdown of the number of subpoenas, court orders and warrants received, the number of customers affected and details about the legal demands it receives.

AT&T has said previously that it protects customer information and complies with government requests for records "only to the extent required by law."

Several major Internet companies, including Google, Microsoft, Apple, Facebook and Yahoo publish periodic reports disclosing the number of requests from federal agencies and local police departments for personal data, which cover such things as email communications.
