About the fee for use fee calculation for income excesses of public housing

There was an error in the fee calculation for some public housing, and it turned out that we have collected an excessive fee for housing fee from 2014 until now. We deeply apologize for the inconvenience caused to the residents of the town, including everyone in the public housing.
We will revise the ordinance from April 1st, 2020 and revise it to a valid rent. Regarding the difference over the past, the residents are not responsible for the information that has not been communicated from the town, and it is difficult for the residents to live under the demand for underpayment in addition to the monthly rent. Since it will lead to an increase, we will not collect additional.
The details of the fee calculation error are as follows.
