This excerpt taken from the RKT 10-K filed Nov 26, 2008.
On January 24, 2007, we acquired for $32.0 million the remaining 40% minority interest in Fold-Pak, giving us sole ownership. We acquired our initial 60% interest in Fold-Pak in connection with the GSPP Acquisition in June 2005. Fold-Pak makes paperboard-based food containers serving a very broad customer base and is a consumer of board from our bleached paperboard mill. We have included the results of these operations in our consolidated financial statements since that date in our Consumer Packaging segment. The acquisition included $18.7 million of intangibles, primarily for customer relationships, and $3.5 million of goodwill. The goodwill is deductible for income tax purposes. We are amortizing the non-goodwill intangibles on a straight-line basis over a weighted average life of 19 years.
