Note 2:

CORRECTION OF ERRORS IN PREVIOUSLY REPORTED FINANCIAL STATEMENTS

In August 2012, management in our environmental segment conducted a physical count of inventory at its operations in Spain. Upon an evaluation of the results of that physical inventory, we determined that our inventory values as recorded were misstated and that these misstatements affected prior periods.

Our previously issued financial statements dating back to 2008 and prior years contain other errors which were not previously corrected as they were immaterial to our previously issued consolidated financial statements. We assessed the materiality of all the errors in accordance with SEC Staff Accounting Bulletin ("SAB") No. 99, Materiality and in accordance with the rollover and iron curtain methods as described in SAB No. 108, Considering the Effects of Prior Year Misstatements in Current Year Financial Statements.

We concluded that these errors were individually and collectively immaterial to our previously issued financial statements. However, under SAB 108, we concluded that there is a reasonable possibility that our financial statements for the twelve months ended December 31, 2012 will be materially misstated if we correct the prior year errors in the current year. As a result, we decided to correct our prior year financial statements even though the errors are immaterial to the financial statements issued in those years. Under SAB 108, correcting prior year financial statements for immaterial errors does not require our previously filed reports to be amended; rather, SAB 108 allows these corrections to be made when we file our prior period consolidated financial statements in our 2012 Form 10-K.

For all periods including and between the twelve months ended December 31, 2008 and the three months ended March 31, 2012, these errors, when combined with the errors in our Spanish operations, decreased net income available to AMCOL shareholders by $2.7. Although there were several errors across various categories, we have summarized the errors into general categories and quantified the amount by which they increased (decreased) net income available to AMCOL shareholders as noted below:

Spain - $2.8 decrease for errors associated with accounting for inventory and other items in our environmental segment's Spanish operations;

South Africa - $0.8 decrease for errors related to the accounting for the acquisition of mineral rights in our minerals and materials segment's chromite operations in South Africa;

Malaysia - $0.3 increase resulting from correcting errors in our oilfield services segment's Malaysian operations, largely relating to improper recognition of expenses and errors in accounting for revenues;

DongMing – adjustments to correct errors made in accounting for accounts payable in this China subsidiary;

Tax - $0.2 increase resulting largely from inaccuracies in the accounting for income tax expense in our international operations; and

$0.4 increase for other insignificant errors we have aggregated together.
