Acquisition of the Optical Components Business of Nortel Networks
Of the total $119.0 million consideration for the optical components business of Nortel Networks in November 2002, the initial allocation to acquired in-process research and development was $7.3 million. This initial allocation was subsequently adjusted following the required review of the purchase price allocation during the second half of 2003, resulting in a reduction of the allocated in-process research and development by $1.7 million, which was recognized as a credit in 2003.
At the time of the acquisition the projects remaining under development at the acquisition date were expected to result in a portfolio addressing tunability, bandwidth, integration, amplification, and managed optical networks. These projects were split into two distinct categories: NPI and TR. The TR projects, which met the criteria for recognition as in-process research and development, were assessed as requiring between one and one and a half years before attaining NPI status. All estimated costs to complete were to be funded from our current cash reserves. The current status of each category is given below.
