Final answer:
Newell was overly optimistic about its merger with Jarden due to its past success in acquisitions, confidence in operational integration, and potential for cost savings and market leverage, which were overshadowed by cultural clashes, strategic issues, and external challenges leading to the merger's failure.
Step-by-step explanation:
Newell was overly optimistic about the value it could generate from merging with Jarden due to a combination of factors. They believed in their proven track record of improving operational efficiencies in acquired firms, as well as dominating product segments.
Their past success made them confident in integrating Jarden's business units and achieving significant cost savings by combining research and development, supply chains, and back-office operations to the tune of $500 million annually.
Moreover, they envisioned leveraging existing relationships in certain business areas, like the infant products market, to boost sales of newly acquired lines.
However, a clash of corporate cultures, strategic misalignment, and external challenges such as supply chain disruptions and problems with retailers, particularly the bankruptcy of Toys R Us, led to unanticipated difficulties and ultimately financial losses.
