+# License exceptions
+
+License exceptions for Apertis are listed below.
+Each exception must provide the following informations:
+
+| name | description |
+| ---- | ----------- |
+| project | The project name |
+| location | The project location (gitlab or OBS) |
+| component | The repository components apertis:*:target |
+| date | The date at which the exception was added to this document |
+| validator | The name of the person who validated the exception |
+| rule | The rules that are ignored by this exception |
+| reason | A description of why the exception is granted and makes sense |
+
+## gcc-5
+
+| name | description |
+| ---- | ----------- |
+| project | gcc-5 |
+| location | OBS |
+| component | apertis:*:target |
+| date | April 17, 2019 |
+| validator | fredo |
+| rule | No GPL v3 |
+| reason | Gcc-5 is granted exception to be present in target repository component |
+| | even though it is licensed under the GPL v3 because it is |
+| | a build time dependency of other projects in target. |
+| | Gcc itself is not delivered on the generated target images. |
+| | It is not intended that the user of Apertis devices uses gcc on the target. |
+| | This usage is explicitely allowed by gcc authors thanks to the |
+| | [GCC Runtime Library Exceptions](https://www.gnu.org/licenses/gcc-exception-3.1-faq.html) |
