verdiavgang

Could you clarify what "verdiavgang" refers to? It isn’t a widely recognized term in English-language reference sources, and it could denote different things in Norwegian—such as a concept in economics/finance (e.g., depreciation or value leakage), a place, a project, or another proper noun. If you provide the intended context or definition, I can craft a concise, neutral wiki-style article under 300 words. If you’d like, I can also propose a generic stub about value depreciation in accounting, and tailor it once you confirm the intended meaning.
