What is the primary reason for the restatement of financial statements in this filing?

The financial statements were restated due to errors identified in the measurement of stock-based compensation expense related to stock options granted in prior years. These errors primarily stemmed from the 'delegated grants' practice and administrative errors in determining the correct grant dates for accounting purposes.

What is the financial impact of the stock option accounting errors?

The restatement increased compensation expense by $2 million for 2006 and $3 million for 2005. While the aggregate cumulative impact from 1994-2005 was considered material, necessitating a restatement, the company stated the impact was not material to any individual reporting period.

What were the key strategic actions taken by Aon during 2006?

Aon divested its Aon Warranty Group and Construction Program Group businesses, repositioning its Insurance Underwriting segment. The company also continued its broad restructuring initiative to improve efficiency and profitability, with significant expected cost savings.

How did the company's share repurchase program evolve in 2006?

The Board of Directors increased the authorized share repurchase program from $1 billion to $2 billion and actively repurchased approximately $1.05 billion worth of shares during 2006.
