Example (1). The Board makes a mathematical error in the computation of an employee's annuity, thus giving the employee a higher rate than he or she is entitled to but which is sufficiently close to the estimated rate given the employee at the time he or she applied for the annuity that the employee believed, in good faith, that the amount was correct. The employee is not at fault in causing the overpayment in this case. The overpayment may be waived if the requirements of § 255.12 or § 255.13 of this part are met.
Example (2). The widow and four minor children of a railroad employee are receiving benefits from the Board under the family maximum. Another minor child not living in the same household as the above individuals is also determined to be the child of the deceased employee. The widow was not aware of the existence of this child. An award of benefits to this child causes a reduction in benefits to the other individuals under the family maximum benefit provision of the Social Security Act. Because of normal administrative delay this reduction does not take place for a period of 2 months after its effective date. The widow and her children are without fault with respect to this overpayment. The overpayment may be waived if the requirements of § 255.12 or § 255.13 of this part are met.
