ALTHOUGH THE PENSION WITHDRAWAL LIABILITY IS A LEGAL OBLIGATION, THE SCIENCE CENTER IS CURRENTLY ONLY REQUIRED TO PAY MONTHLY INSTALLMENTS OF APPROXIMATELY $561 INTO PERPETUITY. THIS AMOUNT IS COMPRISED OF ENTIRELY INTEREST EXPENSE; THEREFORE, NO REDUCTION WILL BE MADE TO THE WITHDRAWAL LIABILITY PRINCIPAL. WHILE THE PRESENT VALUE OF SCHEDULED PAYMENTS COULD CHANGE IN THE FUTURE BASED ON AN ACTUARIALLY CALCULATED ADJUSTMENT, CHANGES TO OTHER EMPLOYERS' OBLIGATIONS, OR SETTLEMENTS REACHED WITH THE PLAN, IT IS QUITE POSSIBLE THAT THE OUTSTANDING PENSION WITHDRAWAL LIABILITY (I.E., THE PRINCIPAL) WILL NEVER BE PAID.
