Graphic Works cover works such as paintings, drawings, diagrams, maps, charts or plans which fall under the group of intangible assets referred to as artistic works. In business valuation analysis, Graphical Works qualify as intangible assets because they are recognisable, separable, and the potential value can be accurately measured. Intangible assets are a class of assets without physical form (such as a building) which generate economic benefits to the owners. To estimate the fair market value of graphical works, business valuation analysts apply techniques under the market, asset and income valuation methods. Owners of graphical works appropriate exclusive rights over the economic benefits associated with their work through intellectual property rights registration which bars third parties from infringing on such works.
