| Expected market expansion due to innovative features of Google watch design | = 80,000 | units | | Develop expansion scope based on Market Research findings |
| (Based on experience with similar products, and algorithms of market behavior) |
| Total anticipated demand for Google Watch Design (full year basis) | = 236,000 | units |
| Phased launch impact (Market introduction on May 12, 2015) | = 7/12 of annual volume | | | First year effect will be partial year if introduced after January |
| Step 3 - Compute Proforma Forecast Results |
| First Year Forecast (7/12 of full year forecast) | = 137,700 | units | | Anticipated demand X phased launch impact |
| Second Year’s Forecast (+3% of full year forecast) | = 243,100 | units | | Full year anticipated demand X Annual Growth factor |
| Third Year’s Forecast (+3% of second year forecast) | = 250,400 | units | | Second year demand X Annual Growth factor |
| Fourth Year’s Forecast (+3% of third year forecast) | = 257,900 | units | | etc. |
| Fifth Year’s Forecast (+3% of fourth year forecast) | = 265,600 | units |
