Saudi Aramco has named at least five new heads of department, including its finance unit, after a government reshuffle last week saw several executives at the oil giant moving to other state posts, according to a media report.

Khalid al-Dabbagh was named acting service line head for finance, strategy and development at the world´s largest oil producer, taking over on a temporary basis from Abdallah al-Saadan, who was senior vice-president of the department, Reuters reports.

In his post, Saadan was effectively chief financial officer of Aramco, overseeing preparations for its initial public offering (IPO), which is now expected to take place in 2019.

Aramco also appointed Motassim al-Maashouq, vice-president of IPO development, to the additional post of vice-president of treasury.
