DUBAI, Sept 29 (Reuters) - Dubai road-toll operator Salik rose 20% above its listing price on its market debut on Thursday in a sign that investors still have appetite for local flotations despite skittish global markets.

The company, which has 3.6 million vehicles registered on the toll system, raised 3.735 billion dirhams ($1.02 billion) by selling a 24.9% stake in its initial public offering (IPO), giving the company a market value of 15 billion dirhams.

Salik was priced at 2 dirhams per share but rose to a high of 2.40 dirhams at the market open on Thursday. ($1 = 3.6727 UAE dirham) (Reporting by Hadeel Al Sayegh Editing by David Goodman )
