The NAB filed three corruption references against the Sharif family in September last year in light of the Supreme Court's July 28 verdict in the Panama Papers case. 

The references pertain to the Al-Azizia Steel Mills, offshore companies including Flagship Investment Ltd, and Avenfield properties of London.

On Saturday, Nawaz did not appear before the NAB Rawalpindi to record his statement with regards to the two references after having been summoned at the regional office.
