4. The relative value relevance of accounting items in banking sector
Prior research’
and motivation
The relative value relevance of accounting items in banking sector
international evidence:
earnings are more value relevant than book values:
in market-based economies
in common law countries
under U.S. GAAP
book values are more value relevant than earnings:
in bank-based economies
in code law countries
under IFRS
cash flows appear to have limited informativeness for equity investors and tend to be significantly less value relevant than earnings
lack of direct evidence in the domestic setting

6. Research design and data sources
Research hypotheses
Hypothesis 1. Book values of equity of banks in the Polish banking sector are more value relevant than net earnings.
Hypothesis 2. Net earnings of banks in the Polish banking sector are more value relevant than cash flows.

Research design - methods
1st Stage: analyses of correlation (Pearson and Spearman)
2nd Stage: simple linear regression:
Model 1.: 𝑝 𝑡 = 𝛼 0 + 𝛼 1 ∙ 𝐵𝑉𝑃𝑆 𝑡 + 𝜀 1𝑡
Model 2.: 𝑝 𝑡 = 𝛽 0 + 𝛽 1 ∙ 𝐸𝑃𝑆 𝑡 + 𝜀 2𝑡
Model 3.: 𝑝 𝑡 = 𝛾 0 + 𝛾 1 ∙ 𝑂𝐶𝐹𝑃𝑆 𝑡 + 𝜀 3𝑡
Model 4.: 𝑝 𝑡 = 𝛿 0 + 𝛿 1 ∙ 𝑁𝐶𝐹𝑃𝑆 𝑡 + 𝜀 4𝑡
where:
pt – closing price of a bank’s share at the end of period t;
α0, β0, γ0, δ0 – intercepts;
α1, β1, γ1, δ1– structural parameters (regression coefficients);
BVPSt –book value per share at the end of period t,
EPSt - net earnings per share for the period (t-1; t),
OCFPSt – operating cash flows per share for the period (t-1; t),
NCFPSt - net cash flows per share for the period (t-1; t),
ε1t, ε2t, ε3t, ε4t – error terms.
3rd Stage: stepwise multiple regression according to the relative explanatory power of particular variables

8. Research design and data sources
research sample: all domestically-based commercial banks listed on the Warsaw Stock Exchange over the period (18 banks)
data sources:
financial statements - Notoria Serwis SA database provided by ISI Emerging Markets
historical stock prices - the database of the Brokerage House of Bank Ochrony Srodowiska SA
the combined data on EPS, BVPS, OCFPS, NCFPS and stock prices yielded the final pooled samples of:
235 bank-year observations for separate financial statements
216 bank-year observations for consolidated financial statements

9. Empirical results

10. Empirical results: 1st Stage
the strongest (positive) relationship between the selected accounting items and banks’ stock prices was found for BVPS (regardless of the employed correlation measure and type of data used (separate or consolidated)
a weaker, yet also strong and statistically significant, positive relationship, was found for EPS
in contrast, correlations for cash flows were either insignificant or very weak (consolidated NCFPS)

11. Empirical results: 1st Stage

12. Empirical results: 2nd Stage
regressions using BVPS and EPS as explanatory variables were statistically significant at the 1% level
highest R2 was found for Model 1. (BVPS) followed by Model 2. (EPS)
the estimates of regression coefficients for BVPS and EPS were positive and statistically significant
the responsiveness of stock prices to changes in EPS was higher than to those of BVPS
consolidated data seems to be of slightly higher value relevance to equity investors
regressions using cash flows as explanatory variables exhibit a very poor fit to the empirical data

14. Empirical results: 3rd Stage
introduction of EPS as an additional explanatory variable to Model 1. provided a relatively small, yet statistically significant, improvement of its predictive power
the attempts to enhance the predictive power of the model through introduction of NCFPS and CFOPS proved to be unsuccessful - for each model the estimated change in R2 turned out to be statistically insignificant at the 5% level

16. Conclusions

17. Conclusions
Conclusions
book values of equity are more value relevant than net earnings
earnings, however, have a statistically significant, incremental explanatory power over book values
cash flows (operating and net):
are of limited informativeness for equity investors in the banking sector
do not exhibit any significant incremental explanatory power over book values and earnings
the findings are consistent with the evidence found in the prior literature and support both hypotheses of the study
