• When writing an alphabetical index, parenthesis are used to separate words moved to the end of a sentence, not a comma.

• Normally, articles are not capitalized unless they need to for some other reason, for example for being the first word of a sentence like: La Banque…

• The owners of a brand name are free to use, break, impose the rules they like.

• Here, the article is technically still the very same one that used to be at the beginning of the phrase, so its uppercase L should be kept as is:

Banque de Nouvelle-Écosse (La)
