Using GetDFPData to obtain annual financial reports from B3

Marcelo Perlin

2018-02-16

Financial statements of companies traded at B3 (formerly Bovespa), the Brazilian stock exchange, are available in its website. Accessing the data for a single company is straightforward. In the website one can find a simple interface for accessing this dataset. An example is given here. However, gathering and organizing the data for a large scale research, with many companies and many dates, is painful. Financial reports must be downloaded or copied individually and later aggregated. Changes in the accounting format thoughout time can make this process slow, unreliable and irreproducible.

Package GetDFPData provides a R interface to all annual financial statements available in the website and more. It not only downloads the data but also organizes it in a tabular format and allows the use of inflation indexes. Users can select companies and a time period to download all available data. Several information about current companies, such as sector and available quarters are also at reach. The main purpose of the package is to make it easy to access financial statements in large scale research, facilitating the reproducibility of corporate finance studies with B3 data.

The positive aspects of GetDFDData are:

Installation

The package is (not yet) available in CRAN (release version) and in Github (development version). You can install any of those with the following code:

# Release version in CRAN
install.packages('GetDFPData') # not in CRAN yet

# Development version in Github
devtools::install_github('msperlin/GetDFPData')

Shinny interface

The web interface of GetDFPData is available at http://www.msperlin.com/shiny/GetDFPData/.

How to use GetDFPData

The starting point of GetDFPData is to find the official names of companies in B3. Function gdfpd.search.company serves this purpose. Given a string (text), it will search for a partial matches in companies names. As an example, let’s find the official name of Petrobras, one of the largest companies in Brazil:

library(GetDFPData)
library(tibble)

gdfpd.search.company('petrobras',cache.folder = tempdir())
## 
## Reading info file from github
## Found 44254 lines for 689 companies  [Actives =  517  Inactives =  173 ]
## Last file update:  2017-10-19
## Caching RDATA into tempdir()
## 
## Found 2 companies:
## PETROBRAS DISTRIBUIDORA SA             | situation = ATIVO | first date = 2016-12-31 | last date - 2016-12-31
## PETRÓLEO BRASILEIRO  S.A.  - PETROBRAS | situation = ATIVO | first date = 1998-12-31 | last date - 2016-12-31
## [1] "PETROBRAS DISTRIBUIDORA SA"            
## [2] "PETRÓLEO BRASILEIRO  S.A.  - PETROBRAS"

Its official name in Bovespa records is PETRÓLEO BRASILEIRO S.A. - PETROBRAS. Data for quarterly and annual statements are available from 1998 to 2017. The situation of the company, active or canceled, is also given. This helps verifying the availability of data.

The content of all available financial statements can be accessed with function gdfpd.get.info.companies. It will read and parse a .csv file from my github repository. This will be periodically updated for new information. Let’s try it out:

df.info <- gdfpd.get.info.companies(type.data = 'companies', cache.folder = tempdir())

This file includes several information that are gathered from Bovespa: names of companies, official numeric ids, listing segment, sectors, traded tickers and, most importantly, the available dates. The resulting dataframe can be used to filter and gather information for large scale research such as downloading financial data for a specific sector.

Downloading financial information for ONE company

All you need to download financial data with GetDFPData are the official names of companies, which can be found with gdfpd.search.company, the desired starting and ending dates and the type of financial information (individual or consolidated). Let’s try it for PETROBRAS:

name.companies <- 'PETRÓLEO BRASILEIRO  S.A.  - PETROBRAS'
first.date <- '2004-01-01'
last.date  <- '2006-01-01'

df.reports <- gdfpd.GetDFPData(name.companies = name.companies, 
                               first.date = first.date,
                               last.date = last.date,
                               cache.folder = tempdir())
## Found cache file. Loading data..

Object df.reports only has one row since we only asked for data of one company. The number of rows increases with the number of companies, as we will soon learn with the next example. All financial statements for the different years are available within df.reports. For example, the assets statements for all desired years of PETROBRAS are:

df.income.long <- df.reports$fr.income[[1]]

glimpse(df.income.long)
## Observations: 48
## Variables: 6
## $ name.company       <chr> "PETRÓLEO BRASILEIRO  S.A.  - PETROBRAS", "...
## $ ref.date           <date> 2005-12-31, 2005-12-31, 2005-12-31, 2005-1...

## $ acc.value.infl.adj <dbl> 61398234.97, -16173000.56, 45225234.41, -24...

The resulting dataframe is in the long format, ready for processing. In the long format, financial statements of different years are stacked. In the wide format, we have the year as columns of the table.

If you want the wide format, which is the most common way that financial reports are presented, you can use function gdfpd.convert.to.wide. See an example next:

df.income.wide <- gdfpd.convert.to.wide(df.income.long)

Downloading financial information for SEVERAL companies

If you are doing serious research, it is likely that you need financial statements for more than one company. Package GetDFPData is specially designed for handling large scale download of data. Let’s build a case with two selected companies:

my.companies <- c('PETRÓLEO BRASILEIRO  S.A.  - PETROBRAS',
                  'BANCO DO ESTADO DO RIO GRANDE DO SUL SA')

first.date <- '2005-01-01'
last.date  <- '2007-01-01'
type.statements <- 'individual'

df.reports <- gdfpd.GetDFPData(name.companies = my.companies, 
                               first.date = first.date,
                               last.date = last.date,

Every row of df.reports will provide information for one company. Metadata about the corresponding dataframes such as min/max dates is available in the first columns. Keeping a tabular structure facilitates the organization and future processing of all financial data. We can use tibble df.reports for creating other dataframes in the long format containing data for all companies. See next, where we create dataframes with the assets and liabilities of all companies:

df.assets <- do.call(what = rbind, args = df.reports$fr.assets)
df.liabilities <- do.call(what = rbind, args = df.reports$fr.liabilities)

df.assets.liabilities <- rbind(df.assets, df.liabilities)

As an example, let’s use the resulting dataframe for calculating and analyzing a simple liquidity index of a company, the total of current (liquid) assets (Ativo circulante) divided by the total of current short term liabilities (Passivo Circulante), over time.

library(dplyr)
## 
## Attaching package: 'dplyr'
## The following objects are masked from 'package:stats':
## 
##     filter, lag
## The following objects are masked from 'package:base':
## 
##     intersect, setdiff, setequal, union
my.tab <- df.assets.liabilities %>%
  group_by(name.company, ref.date) %>%
  summarise(Liq.Index = acc.value[acc.number == '1.01']/ acc.value[acc.number == '2.01'])

my.tab
## # A tibble: 3 x 3
## # Groups:   name.company [?]
##   name.company                            ref.date   Liq.Index
##   <chr>                                   <date>         <dbl>
## 1 BANCO DO ESTADO DO RIO GRANDE DO SUL SA 2006-12-31     0.725
## 2 PETRÓLEO BRASILEIRO  S.A.  - PETROBRAS  2005-12-31     0.937
## 3 PETRÓLEO BRASILEIRO  S.A.  - PETROBRAS  2006-12-31     0.973

Now we can visualize the information using ggplot2:

library(ggplot2)

p <- ggplot(my.tab, aes(x = ref.date, y = Liq.Index, fill = name.company)) +
  geom_col(position = 'dodge' )
print(p)

Exporting financial data

The package includes function gdfpd.export.DFP.data for exporting the financial data to an Excel or zipped csv files. See next:

my.basename <- 'MyExcelData'
my.format <- 'csv' # only supported so far
gdfpd.export.DFP.data(df.reports = df.reports, 
                      base.file.name = my.basename,
                      type.export = my.format)

The resulting Excel file contains all data available in df.reports.
