Taking the above points into account, if HBO invests an average of $10 to acquire a user through its marketing strategies and predicts that the Roku button could attract an additional 500,000 users within a year, the estimated “value” of this button would be $5 million. Additionally, if the easy access to the button encourages users to select HBO over its competitors, contributing another estimated value of $3 million, the total value would amount to $8 million. However, we should reduce this value by a 30% risk factor, as these are theoretical situations and we need to account for some uncertainty. This adjustment brings the figure down to $5.6 million for a single year. By examining similar agreements, we can determine whether this figure aligns with the current market rate. Ultimately, HBO might consider negotiating to pay this amount in installments or linking part of the payment to the number of Roku devices sold to mitigate the risk involved.
