Ann gives a check to Beta Investments to buy 100 shares of stock in Computer Technology Corporation for Ann. The price of the shares is constantly fluctuating. Beta asks Ann to leave the amount of the check blank and allow Beta to fill in the price when making the purchase. Ann agrees. Beta buys the stock when the price is $4,000, but fills in the check for $5,000. The check is negotiated as payment for a $5,000 debt to Delta Accounting Services, which takes the check in good faith and without no¬tice of Beta’s act. Delta later learns that Beta was not authorized to fill in the check for $1,000 over the price. Is Delta an HDC? If so, for how much?
