(a) Research and development authorities. The Board, with the approval of the Secretary, may establish or provide for the establishment of production research, marketing research and development projects, and marketing promotion, including paid advertising, designed to assist, improve, or promote the marketing, distribution, and consumption or efficient production of walnuts. The expenses of such projects shall be paid from funds collected pursuant to §§ 984.69 and 984.70 and may be credited back pursuant to paragraphs (b) and (c) of this section.

(b) Credit-back for promotion expenses. The Board may provide for crediting the pro rata expense assessment obligations of a handler with such portion of his or her direct expenditure for marketing promotion, including paid advertising, as may be authorized. The credit-back amount available to each handler shall be determined by that handler's percent of the industry's total volume of walnuts handled during the prior marketing year multiplied by the current marketing year's credit-back program budget. No handler shall receive credit-back for any creditable expenditures that would exceed the total amount of credit-back available to him or her for the applicable marketing year. Further, no handler shall receive credit-back in an amount that exceeds that handler's assessments paid in the applicable marketing year at the time the credit-back application is made. Marketing promotion expenses shall be credited at a rate recommended by the Board and approved by the Secretary, where the credit rate is based on the amount per dollar of marketing promotion expenses for creditable expenditures paid by a handler during the applicable marketing year. Credit may be paid directly to the handler as a reimbursement of assessments paid or may be issued as recommended by the Board and approved by the Secretary. The Board may also establish, subject to the approval of the Secretary, different credit rates for different products or different marketing promotion activities according to priorities determined by the Board and its marketing plan.

(c) Creditable expenditures. The Board, with the approval of the Secretary, may credit-back all or any portion of a handler's direct expenditures for marketing promotion including paid advertising that promotes the sale of walnuts, walnut products or their uses. Such expenditures may include, but are not limited to, money spent for advertising space or time in newspapers, magazines, radio, television, transit, and outdoor media, including the actual standard agency commission costs not to exceed 15 percent, or as otherwise recommended by the Board and approved by the Secretary.
