Significant estimates relate to allowances for doubtful accounts, inventory reserves, self-insurance reserves related to healthcare and workers compensation, deferred taxes, post retirement benefits, progress billings for tooling, goodwill and long-lived assets. Actual results could differ from those estimates.</font></div></div>
