• Usage: meaning costs will be based on actual or planned costs;

• Business specific: meaning that no allocation methods are necessary as the related cost center captures costs of one business exclusively;

• Time spent: meaning a direct reflection of the support provided to each business;

• Headcount FTE: meaning costs will be allocated to each business based on the percentage of each business’s FTE to sum of total FTE; and

• Percentage of operating expenses: meaning certain costs are allocated to businesses based on the overall percentage of costs being absorbed by each business

Mark-up

Servicing Party will charge Receiving Party at the cost of Servicing Party’s expenses plus 2%.

The Parties intend for the cost allocation, in all cases, to be on terms and under circumstances, including credit standards (if applicable), that are substantially the same or at least as favorable to the Bank or Bank subsidiary as those prevailing at the time for comparable transactions with or involving unaffiliated third parties. The Parties shall not impose any allocation on the Bank or Bank subsidiary that is inconsistent with that intent and, if it is determined by the Bank or Bank subsidiary in good faith or any regulatory body with supervisory authority over the Bank that an allocation hereunder is inconsistent with that intent, the Parties shall promptly modify the terms accordingly and shall adjust any prior allocations that violate that intent.

The parties agree that the fees payable to the Servicing Party hereunder shall not exceed the fees the Servicing Party would have received for similar services provided to an unaffiliated third party.
