Such companies tend to adopt their own unique approaches to value brands to face increasing competition, which is also reinforced by the fact that brand constitutes the company's most valuable commercial and intangible assets. The paper compares selected internationally recognized brand valuation methods, using the mathematical statistics apparatus (Pearson and Spearman correlation coefficients), on the sample of 12 global well-known brands (Apple, Google, Microsoft, Coca-Cola, Facebook, Toyota, IBM, Disney, McDonald's, General Electric, Samsung and Amazon).
Purpose of the article: The aim is to analyze the brand values and the methods applied for possible deviations, and identify whether they are statistically significant and/or find any statistical correlation, or eventually recognize them as totally different and independent approaches.
Methods: The analysis is carried out by pairwise comparison of selected brand values provided by selected consultative companies (Forbes, Interbrand, Brand Finance and Millward Brown). The degree of correlation of brand values provided by respective consultative groups is calculated using the following correlation coefficients: Pearson's correlation coefficient and its modified non-parametric version involving ordinals — Spearman's rank correlation coefficient.
Findings and Value added: The analysis proved the highest correlation of the brand values provided by the Forbes and Interbrand; Subsequently, a trend analysis is carried out to determine the development over time, identifying the most striking development in the brand values provided by Millward Brown (BrandZTM) for the period 2013–2016.
