international paper entered into an agreement in 2000 to guarantee , for a fee , an unsecured con- tractual credit agreement between a financial institution and an unrelated third-party customer .
in the fourth quarter of 2006 , the customer cancelled the agreement and paid the company a fee of $ 11 million , which is included in cost of products sold in the accompanying consolidated statement of oper- ations .
accordingly , the company has no future obligations under this agreement .
in connection with sales of businesses , property , equipment , forestlands and other assets , interna- tional paper commonly makes representations and warranties relating to such businesses or assets , and may agree to indemnify buyers with respect to tax and environmental liabilities , breaches of repre- sentations and warranties , and other matters .
where liabilities for such matters are determined to be probable and subject to reasonable estimation , accrued liabilities are recorded at the time of sale as a cost of the transaction .
under the terms of the sale agreement for the bever- age packaging business , the purchase price received by the company is subject to a post-closing adjust- ment if adjusted annualized earnings of the beverage packaging business for the first six months of 2007 are less than a targeted amount .
the adjustment , if any , would equal five times the shortfall from the targeted amount .
while management does not cur- rently believe that such adjustment is probable based upon current projections , it is reasonably possible that an adjustment could be required in international paper does not currently believe that it is reasonably possible that future unrecorded liabilities for other such matters , if any , would have a material adverse effect on its consolidated financial statements .
