                   The following information relates to a construction contract:

                                                           $
                   Contract price                       500,000

                   Costs to date                        300,000
                   Estimated costs to completion        100,000

                   Value of work certified to date      400,000
                   The stage of completion may be estimated either using cost values (inputs) or
                   sales values (outputs).

                   Inputs


                   Stage of completion is calculated by comparing costs to date to estimated
                   total costs:

                                300,000

                          —————————                     =    75%
                         (300,000 + 100,000)

                   Outputs

                   Stage of completion is calculated by comparing work certified to date to total
                   contract price:

                                400,000
                                ————                    =    80%

                                500,000
