’ Where loyalty counts ’

How it reads. Profit is figured on the head you buy back (the replacements), so the extra head sold beyond your replacements show as a return of capital, not trading profit. Days held = weight gain ÷ ADG. Interest on carry excludes agent commission, since that only falls due at sale. Losses reduce profit by the purchase cost of any head that don't make it to sale. This is a demonstration with figures you can edit — not financial advice, and the interest and return-on-capital conventions are adjustable to match your lender and accounting basis.
