Volkswagen says it is postponing release of its full-year earnings as well as its annual shareholder meeting due to open questions about its diesel emissions scandal.

The company said Friday it would give new dates for the earnings release, formerly slated for March 10, and for its shareholder gathering originally set for April 21.

It said questions about how the matter will be resolved left open what it described in a statement as "valuation calculations."

Volkswagen says it is sticking to its plan to publish the findings of its investigation into the background and responsibilities of the scandal in the second half of April.

The Wolfsburg, Germany-based automaker has admitted equipping cars with software that let them cheat on diesel emissions testing.
