Allowance for Doubtful Trade Receivables
We make estimates of the uncollectability of our trade receivable based on historical trends and other factors such as ageing and economic trends. Adverse economic conditions or other factors that might cause deterioration of the financial health of customers could change the timing and levels of payments received and necessitate a change in estimated losses.
Accounting for Defined Benefit Plans
In accounting for pension and post-retirement benefits, several statistical and other factors that attempt to anticipate future events are used to calculate plan expenses and liabilities. These factors include expected return on plan assets, discount rate assumptions and rate of future compensation increases. To estimate these factors, actuarial consultants also use estimates such as withdrawal, turnover, and mortality rates which require significant judgment. The actuarial assumptions used by us may differ materially from actual results in future periods due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates, or longer or shorter participant life spans.
