we adopted the new asc 606 standard as of january 1 2018 and elected to use the modified retrospective method .
historical hardware sales prior to the adoption of asc 606 were recorded on a gross basis as we were the principal in the transaction in accordance with the previous standard asc 605-45 .
under the new standard we are an agent in the transaction as we do not physically control the hardware which we sell .
accordingly starting january 1 2018 we recognize our hardware revenue net of related cost which reduces both hardware revenue and cost of sales as compared to our accounting prior to 2018 .
for comparison purposes only had we implemented asc 606 using the full retrospective method we would have also presented hardware revenue net of cost for prior periods as shown below .
