This article explores the measurement and assessment of Tone at the Top (TATT) in CEO letters of Dutch listed companies (AEX) over a 10 year period. A combination of quantitative (text analysis) and qualitative research (close reading) is conducted. The main findings indicate that measured TATT is relatively stable for AEX companies over time. However, at closer examination significant deviations from the mean TATT are evident. Possible explanations are provided for these out-of-range TATT scores through the identification of several variables, e.g., difficult operating circumstances, investments and disinvestments, changes in the composition of supervisory boards, corporate governance, and compliance with law and regulations.
Tone at the top, CEO letters, DICTION
Several corporate scandals have occurred during recent decades. Unravelling the underlying causes of each scandal can be complicated. Due to these scandals, regulations have increased significantly, in particular for listed companies. In addition to SOx in the United States (
This article focuses on the concept of TATT within a Dutch context, in particular at AEX-listed companies over a period of 10 years. This topic has received limited academic attention until now, however the impact of TATT can be significant (
The disposition of this article is as follows. Section 2 discusses prior research and outlines the different definitions and theories regarding TATT and related concepts such as leadership, culture and communication. TATT has been defined in various ways and its measurement is not unequivocal. Thereafter, the use of CEO letters as a basis for quantifying TATT is discussed (
This section provides relevant definitions, prior literature, and a theoretical framework. Several articles on TATT (e.g.,

Sections 2.1 and 2.2 focus on the proxy variable of this article, i.e. the “(un)ethical TATT”. This variable is based on analyzing CEO letters. In addition to the construct of this proxy variable, a list of possible explanatory variables is presented, offering possible explanations for a certain level of TATT. These possible explanatory variables are based on a review of (academic) resources (e.g.,
For example, one of the identified variables is Internal audit environment. As is stated by Hansen, Stephens, Wood (2009) “we identify six potential ways the Internal Audit Function may increase its ability to improve the tone at the top”. Also

TATT is considered to be the proxy variable in the study. TATT is operationalized by analyzing CEO letters with the use of text analysis. This quantitative analysis results in measuring and visualizing possible outliers of “(un)ethical TATT” (see section 4).
In this framework, the term TATT is introduced twice. In the upper box, the representation of TATT is of a qualitative nature; TATT represented in the lower box is the quantitative representation after analyzing CEO letters, i.e., the score, measured by the textual-analysis program.
The applicable out-of-range CEO letters, i.e. a score more than 2 standard deviations from the mean resulting from text analysis, are further analyzed by close reading, taking into account the scores from text analysis as well as the identification of possible explanatory variables. The combination of both the analytical power of text analysis and close reading is in line with previous research, such as

For the analysis of CEO letters, as an indicator for TATT, a text analysis program named DICTION is used. DICTION has a dictionary-based approach and uses a built-in database consisting of 50,000 previously analysed texts (DICTION manual). DICTION uses 31 standard dictionaries (word lists) to search a given text. DICTION processes the text, looking for an exact match of the words contained in the 31 standard dictionaries (Diction manual). The 31 dictionary measures have labels such as ‘numerical terms’, ‘ambivalence’, ‘self-reference’, and ‘tenacity’. In addition, based on the text processing described above, DICTION produces measures of 4 calculated variables (‘insistence’, ‘embellishment’, ‘variety’ and ‘complexity’) by linguistically based methods of calculation.
The above-mentioned DICTION-related 31 dictionary measures, as well as the 4 calculated variables (35 in total) are used to calculate the 5 master variables of DICTION (certainty, activity, optimism, realism and commonality).
The definitions of these 5 master variables (DICTION manual) are mentioned below:
These 5 master variables are used as building blocks for quantifying TATT.
After importing the CEO letters into DICTION, the program calculates the master variables, derived from the 35 underlying variables. To be able to operationalize the concept of TATT, an all-inclusive TATT score is calculated. The construct of the TATT score is based on DICTION’S 5 master variables. Some variables have a positive relationship with TATT, whilst others have a negative connotation. The formula for the TATT score is:
(2 ×Realism + 2 ×Commonality - 1 ×Activity - 1 ×Optimism - 2 ×Certainty) ÷ 8
Both the use of a positive/negative connotation as well as the use of different weighting factors, per master variable, are based on Patelli and Pedrini’s research (2014, p. 14, Table
To determine outliers in TATT scores in this analysis, a lower and upper bound range are constructed by subtracting and adding 2 standard deviations from the mean value per master variable. The choice for applying 2 standard deviations is in line with research of
Subsequently, the out-of-range CEO letters in this research are studied in a qualitative manner by means of close reading. Close reading is one of the available qualitative methods for assessing the TATT of a company. This is in line with the research design of
This section describes the analysis and results of this research. Section 4.1 contains descriptive statistics. These statistics are analyzed to determine the TATT outliers which are presented in Section 4.3. A qualitative review takes place in section 4.4 to validate the master variables on a manual basis and to explore the presence of possible explanatory variables for out-of-range TATT-scores.
The full data set contains 218 individual observations. The time span is 10 years (2007–2016). In this period 38 companies were part of the AEX index and under examination for this article. Some companies are only present for one year, while others are represented in the AEX index for the full 10 year period. As discussed in section 3.2, 35 variables are used to calculate the 5 master variables. Please see Table
Applying descriptive statistics (e.g., standard deviation) to the data set implies a normal distribution of the underlying data points. In order to interpret Table

Two important remarks have to be made about this table:
In the aforementioned section, 11 outliers are determined. These letters qualify for the next step of analysis: close reading. Exceptional sentences in each out-of-range CEO letter, indicating an out-of-range score on one or more master variables, are determined. The explanatory variables checklist is used to read and analyse each letter and an initial attempt is made to link one or more potential explanatory variables (section 2.3.) to each CEO letter.
The following steps for each out-of-range CEO letter are executed:
In the close reading exercise of section 4.4, one or more explanatory variables per out-of-range CEO-letter are identified. Table

The following findings can be derived from Table
The CRQ of this study is:
‘To what extent is it possible to quantify Tone at the Top at AEX-listed companies from 2007 to 2016 and consequently, what findings and trends can be derived from the results?’
Based on the research conducted, the answer to the research question is twofold:
This article contributes to academic research and also has a few relevant practical implications. However, the research also comes with some caveats, grouped in 4 categories:
CEO letters are used as a representation of TATT, in line with prior research as shown in section 2. The question remains whether these documents fully reflect the TATT. A CEO letter is a rather rough proxy, because measuring TATT is more subtle and nuanced. Usually, CEO letters are drafted not only by the CEO, but by several officers (e.g., investor relations and disclosure committees). The final version of the previous year could be a starting point for the new CEO letter as well (‘copy paste exercise’). So to what extent is the CEO letter a true representation of the CEO’s mind set? Analysis of CEO letters could therefore be supplemented by analysis of conference calls (e.g., Q&A after Analyst Presentation) or meetings without a pre-defined transcript, e.g. unstructured and/or unscheduled meetings (
This quantification tool is limited to a predefined set of thematic indicators. This can be perceived as either a strength or a weakness. The strength is objectivity and reliability of the measure, given the extensive use of the program in prior discourse analysis. However, inflexibility can be considered a weakness. Also, DICTION may not capture the context in which a word appears in full.
Constructing TATT using DICTION has not been executed so far according to the authors’ knowledge. Thus, the approach to employ DICTION to assess TATT is experimental. The construct of the TATT score (see 3.3) in this article is consistent with the assumptions used in Patelli and Pedrini’s research (2014, p. 14, Table
The results of this research may also be influenced by the occurrence of endogeneity, i.e., the possible impact of one of the explanatory variables on TATT may also be influenced by the existence of other unknown explanatory variables.
Based on the outcome of this study several areas for future research can be considered.

A sensitivity analysis has been conducted to check the robustness of the TATT outliers. Based on the current proxy, 11 out of 218 CEO letters are classified as outliers. Using the alternative proxy (i.e. all master variables are equally weighted), 8 out of these 11 cases are also classified as outliers.
