(“Centina”), a provider of service assurance analytics and network performance management solutions, for approximately $34.0 million in cash. This transaction has been accounted for as the acquisition of a business.

Customer relationships and contracts represent agreements with existing Centina customers and have an estimated useful life of two years. Developed technology represents purchased technology that has reached technological feasibility and for which Centina had substantially completed development as of the date of acquisition. Fair value was determined using future discounted cash flows related to the projected income stream of the developed technology for a discrete projection period. Cash flows were discounted to their present value as of the closing date. Developed technology is amortized on a straight-line basis over its estimated useful life of five years. The goodwill generated from the acquisition of Centina is primarily related to expected economic synergies. The total goodwill amount was recorded in the Blue Planet Automation Software and Services segment. The goodwill is not deductible for income tax purposes. Pro forma disclosures have not been included due to immateriality.
