Final answer:
The primary reason that a serviced institution should continue to monitor a servicer's financial condition, audit reports, and compliance with performance standards when trust operations are outsourced is fiduciary liability and most of the responsibility for the accuracy and security of customer accounts remain with the serviced institution, not the servicer.
Step-by-step explanation:
The primary reason that a serviced institution should continue to monitor a servicer's financial condition, audit reports, and compliance with performance standards when trust operations are outsourced is option a. Fiduciary liability and most of the responsibility for the accuracy and security of customer accounts remain with the serviced institution, not the servicer.
This means that while the servicer may be handling the actual operations, the serviced institution is still ultimately responsible for the accuracy and security of customer accounts.
By monitoring the servicer's financial condition, audit reports, and compliance with performance standards, the serviced institution can ensure that the servicer is meeting the necessary requirements to protect customer accounts.
