Material estimates that are particularly susceptible to change in the near term relate to the allowance for credit losses, off-balance sheet credit exposures, available for sale securities, the accounting for business combinations including subsequent impairment analyses for goodwill and other intangible assets, accounting for income taxes, post-retirement benefits, and asset impairment assessments.</p>
