Temporary power group Aggreko (LON:AGK) is among the companies due to report on its progress on Tuesday, and will update the market on its hunt for a new chief executive.
Current boss Rupert Soames is on the way out at the end of the month after being poached by troubled outsourcer Serco (LON:SRP).
Angus Cockburn takes the reins on 24 April unless a new CEO is appointed before then.
Last month, the group unveiled plans to return £200mln to shareholders.
Due to strong cash generation in 2013 the board said it planned to supplement the ordinary dividend with an additional return to shareholders equivalent to 75p a share.
The dividend was also up 10% with a full-year dividend of 26.30p per share, the company revealed in its full year results, which showed a drop in profits as expected.
Also set to update investors on trading are mining heavyweight Rio Tinto (LON:RIO), Peroni brewer SABMiller (LON:SAB), while department store chain Debenhams (LON:DEB) releases interims and JD Sports (LON:JD.) reports its final figures.

Interim results: Punch Taverns (LON:PUB), Debenhams (LON:DEB).
