Guarantees	NOTE G – Guarantees We do not have guarantees that we believe are reasonably likely to have a material current or future effect on our consolidated financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. However, as of February 28, 2015, we were party to an operating lease for an aircraft in which we have guaranteed a residual value at the termination of the lease. The maximum obligation under the terms of this guarantee was approximately $12,036,000 at February 28, 2015. We have also guaranteed the repayment of a $2,083,000 term loan entered into by one of our unconsolidated affiliates, ArtiFlex. Based on current facts and circumstances, we have estimated the likelihood of payment pursuant to these guarantees, and determined that the fair value of our obligation under each guarantee based on those likely outcomes is not material and, therefore, no amounts have been recognized in our consolidated financial statements.
