Empirical evolution of credit risk over a decade in IBEX 35 companies and its relationship with the qualification of its ratings

Abstract

Purpose: The present work responds to two objectives. On the one hand, it describes the evolution of the main economic-financial indicators that influence credit risk (insolvency) for a sample of 10 Spanish companies listed on the IBEX 35.This analysis is studied for a comparative period of 10 years, which coincides with a pre-crisis stage (2002-2005) and an economic post-crisis phase (2012-2015).On the other hand, it corroborates the relationship between the analysed insolvency and the rating or credit-risk rating published for these companies by an internationally recognized credit rating agency, Standard& Poor's (S & P). Design/methodology: A sample of 10 companies and a 10-year period including the years 2002-2005 (pre-crisis) and the years 2012-2015 (post-crisis) are chosen, omitting the Spanish economic crisis that occurred in the year 2008. For the study of its evolution, 6 ratios obtained from the scientific literature that relate to credit risk and its effects on investments and company results are calculated. Finally, the correlations of these variables with the ratings of credit risk assessment by the rating agency S & P are measured. Descriptive statistics will assign value and graphics to this ten-year evolution, and with the incorporation of a factorial analysis, the correlation between the ratios and the S & P rating will be determined. The statistical analysis explains this correlation to a greater extent. Findings: The results show a clear increase in the value of the impairment variable due to credit risk ten years later that directly affects the results of the companies, despite these companies having significantly reduced their investments in commercial loans pending collection and drastically reduced the period means of collection of clients. In turn, there is a clear correlation between the insolvency studied and the variables used by the S & P rating agency for the assessment of credit risk. Originality/value: The empirical study concludes that there is a correspondence between insolvency and the rating given by an internationally prestigious rating agency (S & P) for the sample of 10 companies studied. Three variables – customer balance-accounts receivable, investments and the net amount of turnover – are determining factors explaining this correlation, and these three variables are the same ones that decisively influence both the pre-crisis period and the post-crisis period 10 years apart. The rating agencies weigh the insolvency variable in their analyses

1. In oduc ion
When a company is inco po a ed in o he business wo ld and assumes he ules o he ma ke s, i is ully awa e
ha his p ocedu e en ails assuming a se ies o isks. One such isk is he isk o de aul ha may esul om he
comme cial ela ionships main ained wi h o he en i ies, which we will call clien -deb o s. We de ine his isk,
called c edi isk, as he possible loss assumed by an economic agen as a consequence o a b each o con ac ual
obliga ions incumben on coun e pa s wi h which i ela es. Such a isk is no subjec o con ol by he agen ,
al hough he agen has he op ion o insu e i h ough duly specialized companies by means o he assump ion

million eu os, almos 14% o he Spanish GDP (Unespa-Insu ance Business Associa ion, 2009).
C edi isk is inhe en o a company, and ze o isk does no exis . The e o e, companies mus lea n o li e wi h
c edi isk and manage he delinquency o hei clien s-deb o s in he bes possible way so ha hei incidence is

La e paymen has been, is and will be a d ag on he business ab ic. Ma iano Reyes w i es (quo ed in B ach ield,

de aul s ha occu in Eu ope a e in en ional and ha he pe cen age o hese de aul s in Spain (5.1%) is double

I seems ha delinquency has become no mal and commonly accep ed. This a iable, which is di icul o

c isis pe iod 2010-2014 (Ins i u o Nacional de Es adís ica, 2017).
Acco ding o da a om he Mul isec o ial Pla o m o Comba ing La e Paymen s (Pla a o ma Mul isec o ial De
Lucha Con a La Mo osidad, 2010), his p oblem is he leading cause o insol ency in Spain in 67% o business
closu es ha ha e occu ed since 2007. The main eason was he delay in he collec ion o in oices, which has
le c edi o s wi hou liquidi y and wi h easu y p oblems.
A company becomes insol en when i canno mee he paymen o i s deb s on he co esponding due da es.
Acco ding o Suá ez (2003), his esul occu s due o poo easu y managemen when asse s ( o al in es men s)
