(AP) — The government and leading Internet companies have agreed to a compromise allowing companies to reveal how often they are ordered to turn over information about their customers in national security investigations.

The Justice Department announced the deal Monday with Google Inc., Microsoft Corp., Yahoo Inc., Facebook Inc. and LinkedIn Corp. Other companies are expected to participate once it’s approved by the Foreign Intelligence Surveillance Court. Companies wanted to make the disclosures to alleviate public speculation about their cooperation with the government. The government opposed the companies’ request, saying it could interfere with national security investigations.

The reporting will be in very general terms. Companies will have to wait six months before releasing information about intelligence orders.
