US internet firm Yahoo is cutting roughly 2,000 jobs as it seeks to reduce costs.
The company employs 14,000 people worldwide.
A spokesperson for Yahoo in London refused to reveal how many staff it employs in Ireland, and how many jobs might be cut in Ireland as part of its plan.
Yahoo Chief Executive Scott Thompson said: "We are intensifying our efforts on our core businesses and redeploying resources to our most urgent priorities.
"Our goal is to get back to our core purpose - putting our users and advertisers first - and we are moving aggressively to achieve that goal."
The struggling internet pioneer announced a restructuring to focus on a "select" group of core businesses and the platforms that support them.
A key focus will be the data that drives "deep" personalisation for users and return on investment for advertisers, the California-based company said.
"Today's actions are an important next step toward a bold, new Yahoo - smaller, nimbler, more profitable and better equipped to innovate as fast as our customers and our industry require," Mr Thompson said.
The company said it would notify approximately 2,000 people that their jobs have been eliminated or would be in the future. It gave no details on the timing of the lay-offs.
Yahoo said it expects the workforce reduction will produce about $375m in annualised savings.
Yahoo also said that it is not seeking voluntary redundancies.
A London-based spokesperson stressed that they are engaging in a strategic realignment, rather than focussing solely on cost reduction.
The company has now embarked on a 30-day consultation period with staff.
The 17-year-old company had more than 14,000 employees at the end of 2011. It also has a large number of software contract workers whose jobs could also be affected in the shake-up.
A Yahoo spokeswoman has said that the 14% workforce reduction was "not across the board" but that "most units have been impacted". She declined to offer further details.
While Yahoo declined to say how many people it employs in Ireland, informed sources said that the company currently has around 200 employees.
If that ratio were applied to the 200 jobs in Ireland, 28 jobs would be lost.
In January 2009, it said it was setting up its European operations headquarters in a significant expansion of its operations in Ireland.
It was expected to create almost 400 new jobs over five years. The project received support from the IDA.
Yahoo investors welcomed the news of the cuts, pushing shares up 0.3% to $15.23 in morning trade in an overall declining market.
Mr Thompson, formerly head of mobile payments firm PayPal, became chief executive in early January after months of turmoil at Yahoo, including deadlocked talks over possibly selling off the company's valuable assets in China and Japan.
Operations income was up 3.5% in 2011 to $800 million, but net earnings fell 14.6% to $1.06 billion, and earnings per share for the year fell to 82 cents from 90 cents.
No spokesperson in Ireland could be contacted.
