Check company classifications

[Clare2D]

I noticed in the interactive report that Siemens is classified as a Power company and they are not. This should be included in the overrides functionality. I will check why they are not classified as Other

[cjyetman]

will discuss this with AR in the next meeting and go from there

maybe this happens because of the mix up about where sectors are merged/defined and possible sets of overrides that are not in sync? see... #343 2DegreesInvesting/data_preparation/issues/14

It's clear that line 191 in this file probably played a role in this: data/fin_sector_overrides.csv

company_name	corporate_bond_ticker	bloomberg_id	fin_sector_override
SIEMENS AG		115746	Power

however, it's not clear to me if this data/fin_sector_overrides.csv or this one 2DegreesInvesting/data_preparation/data-raw/fin_sector_overrides.csv is currently relevant (the latter does not include "SIEMENS AG' or any reasonable variation)

There have been discussions in #343 and 2DegreesInvesting/data_preparation/issues/14 about the confusion between having and maintaining multiple copies of this file (there's also one in stress testing here: r2dii.stress.test.data/data-raw/fin_sector_overrides.csv).

I think maybe this will get addressed when 2DegreesInvesting/data_preparation/issues/14 is addressed, just leaving lots of links pointing to all relevant stuff for the future.
