Code | tpc0021
Comment | If a household income at inception is reported, meaning that it is not reported as "Non-applicable", then it must be larger than 0. To phase in the check, and to strike a balance between the wish of DNB to have as complete data as possible, and reporting agents possibilities to deliver the data, the rule will be phased in according to this schedule: • Per Q2 2020 ‘Household income at inception’ will be delivered as non-zero value on a best effort basis. • Per Q3 2020 ‘Household income at inception’ will be delivered as non-zero value for at least all instruments with an inception date starting from 01-01-2018. • Per Q4 2020 ‘Household income at inception’ will be delivered as non-zero value for at least all instruments with an inception date starting from 01-01-2016. • Per Q1 2021 ‘Household income at inception’ will be delivered as non-zero value for at least all instruments with an inception date starting from 01-01-2012. DNB will use plausibility checks to monitor the compliance rate of reporting agents. These checks will be run after the delivery has been accepted.
