Mattel ( MAT) posted higher fourth-quarter profit, thanks mostly to a tax gain, "despite a challenging retail environment." The California-based toymaker reported net income of $284.3 million, or 68 cents a share, compared to last year's fourth-quarter net income of $213.9 million, or 49 cents a share.
