* To buyback up to $150 mln in shares from time to time
* Initiates regular quarterly dividend
* Shares off 4 pct on NYSE
The first quarterly dividend of 25 cents per share will be paid on July 15 to shareholders of record on June 15, the company said.
Domtar said under the buyback program, the dual listed company is authorized to repurchase, from time to time, shares of its outstanding common stock on the open market or in privately negotiated transactions in the United States.
Last week, Domtar posted a first-quarter profit that beat market estimates, aided by price increases and higher pulp, paper and wood shipments. [ID:nSGE63J0HV]
