UPDATE 1-Renault details stock buyback programme

(Adds details)

PARIS, April 17 (Reuters) - French carmaker Renault (RENA.PA) said on Thursday it was proposing a ceiling of 2.9 billion euros ($4.63 billion), or 10 percent of its equity, for share buybacks worth up to 150 euros per share.

Renault said its shareholders would vote on the buyback programme at the company's annual shareholders meeting scheduled on April 29.

It said the buyback programme was aimed at using shares for stock option plans, cancelling them, providing liquidity on the secondary market, or using them as payment for external growth in the future.

Renault said it owned 3.16 percent of its shares, currently limiting the amount to be bought back to 6.84 percent but this percentage could change depending on a possible change in outstanding capital agreed upon by its shareholders. (Reporting by Gilbert Kreijger; Editing by Erica Billingham)
