Final answer:
The question asks for a specific monetary threshold for check approval in a business setting, but without the company's policy details, an accurate answer cannot be provided. Generally, higher value checks tend to require managerial approval, but the exact amount can vary between companies.
Step-by-step explanation:
The question does not provide sufficient context or information to correctly answer what the specified threshold amount is for requiring managerial approval on checks. In a business setting, different companies may have various policies regarding the threshold amount at which checks need to be approved by a member of management or the customer service manager. This policy is usually put in place to prevent fraud or mishandling of funds and to ensure that transactions of a high value or of a suspicious nature are verified for legitimacy. The question identifies Certegy, which is a check authorization service that businesses use as a part of their risk management processes.
To proceed with answering this question accurately, one would need the specific policy details from the company in question. As a tutor, I can suggest that, in general, higher value checks (such as those over $500 or $1,000) are more likely to require additional verification, while smaller checks (like those for $50) are less commonly subject to such strict scrutiny.
