The influence of business strategy on annual report readability

Abstract Concerns about the complexity of firm disclosures have prompted regulators to initiate projects to improve the readability of annual reports. We investigate business strategy as a determinant of annual report readability. As business strategy fundamentally determines a firm’s product and market domain, technology, and organizational structure, it influences a firm’s operating complexity, environmental uncertainty and information asymmetry. Consequently, business strategy frames the level, wording, and complexity of disclosures. We capture a firm’s business strategy based on the Miles and Snow (1978) strategic typology and measure 10-K readability with Li’s (2008) Fog index. We find that firms pursuing an innovation-oriented prospector strategy have less readable 10-Ks relative to firms pursuing an efficiency-oriented defender strategy. We also find that prospectors display more negative and uncertainty tones while defenders exhibit more litigious tone in their 10-Ks. Our study provides useful insights to policy makers as it suggests that efforts to improve annual report readability may be limited for some firms given that business strategy is a fundamental determinant of readability and pronouncements accommodating different strategic orientations are not feasible.
