The State must comply with its pecuniary obligations by payment in United States dollars or the equivalent amount in national currency, using the exchange rate between the two currencies in force on the New York, United States of America, market the day prior to payment to make the respective calculation. 421. The amounts allocated in this judgment for compensation for pecuniary and non-pecuniary damage, and for reimbursement of costs and expenses may not be affected, reduced or conditioned by current or future taxes or charges. Consequently, they must be delivered to the beneficiaries integrally, as established in this judgment. 422. In the case of the compensation ordered in favor of minors, the State shall deposit it in a solvent Colombian banking institute. The investment must be made within one year, in United States dollars, and in the most favorable financial conditions permitted by law and banking practice, until the beneficiaries come of age. It may be withdrawn by any of them when they come of age or previously, if this is in the best interests of the child, as established by a decision of a competent judicial authority. If the compensation has not been claimed 10 years after each child has come of age, it shall revert to the State with the accrued interest. 423. If, for reasons attributable to the next of kin of the persons disappeared and deprived of life who are the beneficiaries of the compensation, it is not possible for them to receive it within the period indicated, the State shall deposit the amount in their favor in an account or a deposit certificate in a solvent Colombian banking institute in United States dollars and in the most favorable financial conditions permitted by law and banking practice. If, after 10 years, the compensation has not been claimed, it shall revert to the State with the accrued interest. 424. If the State falls into arrears, it shall pay interest on the amount owed, corresponding to banking interest on arrears in Colombia. 425.

The case will be closed when the State has fully complied with all its terms.
