The McClatchy Co., which owns The Kansas City Star, on Thursday reported lower revenue and profit for the fourth quarter, citing disappointing December holiday advertising.

Sacramento-based McClatchy said its profit excluding one-time adjustments fell to $33.8 million from $43.2 million.

The one-time adjustments, including a $60 million after-tax loss because of the costs of a major debt refinancing, plunged McClatchy into a bottom-line net income loss for the quarter and all of 2012.

Revenue actually grew 1.2 percent during the quarter, but that was because the 2012 quarter had 14 weeks instead of the 13 weeks for the 2011 quarter. On a comparable basis, revenue fell 5.3 percent and advertising revenue fell 6.3 percent.

The results showed that McClatchy, while making progress, has still been unable to shake an advertising downturn that has gripped much of the traditional media industry since 2006. Ad revenue fell 6.1 percent for all of 2012, compared with a decline of 7.7 percent the year before.

“In spite of a softer-than-expected Christmas season for our advertisers, our ad revenue picture improved through most of 2012," said president and chief executive Pat Talamantes in a statement.

For the full year, the company lost $100,000, compared with a gain of $54.4 million in 2011.

The bottom-line numbers were skewed by millions spent refinancing debt. In early December, the company said it was able to refinance about $846 million in bonds, roughly half its total debt.

The move pushed back the maturity on those bonds five years to 2022, giving McClatchy additional breathing room as it deals with the advertising slump and the ongoing transition to a hybrid print-digital world..

During the fourth quarter, digital advertising grew 3.5 percent. Online advertising now makes up 20.2 percent of McClatchy advertising.
