Yahoo chief executive Carol Bartz on Tuesday asked investors to wait until 2012 to judge her competence.
Speaking at the UBS media investor conference in New York, Bartz admitted that some investors were growing impatient with the performance of the search company. She reminded them that it would take two years to resolve technical issues on which Yahoo had fallen behind.
"It does take time to work under the hood. It's nice to see the car running down the highway, but if you are trying to change the tires at the same time, it is a little precarious," she added.
Even 2011 results would not be along the expected lines as Yahoo had recently cut a deal with Microsoft which will power Yahoo searches in exchange for 12 per cent of the revenues the search company generates.
She asked investors not to make year-on-year comparisons yet as they are likely to be misleading. "One year has full revenues; the other has minus 12 per cent," she added.
She was, however, optimistic, about Yahoo's performance in 2012.
