Trade and other payables: amounts falling due after more than one year | 20. Trade and other payables: amounts falling due after more than one year The following are included in trade and other payables falling due after more than one year:
|  | 2019 £m |  |  | 2018 £m |
Payments due to vendors (earnout agreements) |  |  | 111.4 |  |  |  | 266.5 |
Liabilities in respect of put option agreements with vendors |  |  | 151.4 |  |  |  | 205.2 |

|  |  | 483.3 |  |  |  | 841.4 |
The Group considers that the carrying amount of trade and other payables approximates their fair value. The following tables set out payments due to vendors, comprising contingent consideration and the Directors’ best estimates of future earnout-related obligations:
|  | 2019 £m |  |  | 2018 £m |
Within one year |  |  | 142.4 |  |  |  | 148.2 |
Between one and two years |  |  | 36.9 |  |  |  | 140.2 |
Between two and three years |  |  | 37.5 |  |  |  | 38.5 |
Between three and four years |  |  | 14.8 |  |  |  | 50.3 |
Between four and five years |  |  | 9.7 |  |  |  | 20.4 |
Over five years |  |  | 12.5 |  |  |  | 17.1 |
|  |  | 253.8 |  |  |  | 414.7 |
|  | 2019 £m |  |  | 2018 £m |
At beginning of year |  |  | 414.7 |  |  |  | 630.7 |
Earnouts paid |  |  | (130.0 | ) |  |  | (120.2 | )
New acquisitions |  |  | 9.6 |  |  |  | 48.6 |
Revision of estimates taken to goodwill (note 14) |  |  | (14.3 | ) |  |  | (68.3 | )
Revaluation of payments due to vendors |  |  | 1.1 |  |  |  | (82.6 | )
Transfer to disposal group classified as held for sale |  |  | (11.5 | ) |  |  | – |
Exchange adjustments |  |  | (15.8 | ) |  |  | 6.5 |
At end of year |  |  | 253.8 |  |  |  | 414.7 |
As of 31 December 2019, the potential undiscounted amount of future payments that could be required under the earnout agreements for acquisitions completed in the current year and for all earnout agreements ranges from £nil to £14 million (2018: £nil to £179 million) and £nil to £1,110 million (2018: £nil to £1,960 million), respectively. The decrease in the maximum potential undiscounted amount of future payments for all earnout agreements is due to earnout arrangements that have completed and payments made on active arrangements during the year, disposal related to the Kantar sale and exchange adjustments, partially offset by earnout arrangements related to new acquisitions.
