International Workplace Group (IWG), the world's largest serviced office provider, has drawn criticism for inconsistent and confusing charts depicting its revenue per available room (rev PAR) metric. The UK-listed company, which owns the Regus and Spaces brands, uses rev PAR to track progress on its 'pivot towards platform' strategy, where it earns fees from managed and franchised offices while partners handle lease costs. However, IWG's presentation methods have changed multiple times, making comparisons difficult.

Initially, charts combined all centers open at various cut-off dates, then shifted to grouping by year of opening. The latest interim results presentation introduced yet another format, with unexplained changes in scale, timing, and missing target lines. Analysts and investors have struggled to interpret the data, prompting IWG to explain that the new approach groups centers by opening year for clarity.

Despite these efforts, discrepancies remain between old and new reporting methods, raising questions about transparency. Additionally, IWG's $250 monthly rev PAR target, originally set at £200 using a GBP/USD rate of 1.25, now appears stale given current exchange rates around 1.35, potentially impacting investor confidence.
