Clearwater Paper Corp., the Spokane-based maker of tissue paper and other products, reported this afternoon fourth-quarter net income of $82.7 million, or $3.87 a diluted share, up from income of $19.9 million, or 84 cents a share, in the year-earlier period.

The most-recent quarter’s financials include a $55.8 million income-tax benefit, which contributed substantially to the results.

The company reported fourth-quarter net sales of $470.2 million, up from $462.7 million in the year-earlier quarter.

Linda Massman, Clearwater Paper’s president and CEO, said in a press release, “Strong fourth-quarter performance reflects the strength of the company’s team to succeed despite the high level of competition in the marketplace.”

For all of 2013, the company posted net income of $107 million, or $4.80 a share, up from $64.1 million, or $2.72 a share, in 2012.

Late last year, the company completed its $100 million share buyback program, through which it repurchased 2.1 million shares.
