[zatro]

Пожалуйста, помогите перевести фразу с этими словосочетаниями :

In absence of Media Audits Net Reach and Reach (R/F) Net Reach and Reach (R/F) Curves, the relevant Advertisers shall be used.

это пункт договора:

To the extent that the validation process identifies any information that was not valid then any data that was incorrect shall be replaced with the correct data. In absence of Media Audits Net Reach and Reach (R/F) Net Reach and Reach (R/F) Curves, the relevant Advertisers shall be used.
