120 payphones to be installed in Sydney

Discount rate to be used is 6%

Lifetime of the payphone is 5 years

Salvage value per payphone at the end of the 5 years is $30,000

Each payphone is expected to provide Advertising revenue cash flows of $6,000 per unit per month

Each payphone is expected to generate Call revenue of $1,000 per month

The rollout and ongoing management requires a dedicated project director , an a salary of $130,000 pa

It is estimated that the Servicing and repair costs across all payphones will be $30,000 per month

The Cost of producing the digital ads is 20% of the estimated revenue
