Introduction
In recent times, the call for reliable fnancial reporting has gained
prominence in Nigeria and global economy at large. Te capability or
incapability of banks to efectively fulfll intermediate mandate has
been the crux of many fnancial crises. Mediating between the surplus
and defcit units within the economy expedites distribution of national
savings, thereby improving investments and national output. In 2005,
the Central Bank of Nigeria mandated every Nigerian bank to increase
capital base from 2 billion naira to 25 Billion Naira in order to enhance
competitiveness in the international market. Noteworthy capital market
expectations were raised and banks were under pressure to achieve
survival and generate higher returns to shareholders. Tis pressure
from the Central Bank of Nigeria has occasioned banks falsifying
accounts, infating earnings and capital. Te need for reliable reports
has led to statutory audit that provides independent authentication of
fnancial statements prepared by banks’ directors.
Auditors are instructed to report fnancial misdemeanors in
company’s accounts to increase transparency and accountability
through fraud detection. Earnings are made up of accruals and cash
items and accruals are basically controlled by company’s stewards.
Management can bloat performance of company and future earnings
predictions through manipulation of accruals resulting in earnings
management. Financial reports contain accounting information which
diferent users use to appraise frm’s performance. Investors use cash
fow statement to make investment decisions thereby creating room for
highly motivated and intelligent management teams to manipulate the
real economic operations to infuence the true picture of a company’s
cash fow from operations. Since accrual accounting measures the
performance of company by recognizing economic events irrespective
of when transactions occur. Earnings management is therefore,
discovered by conducting tests on the components of accrual assumed
to be at the managerial discretionary accruals thereby revealing
information asymmetries. Accounting scandals experienced in the last
few years have afected the regulators’ trust of fnancial statements. Tis
scandal and its consequent results are reasons for drawing attention
to quality and reliability of fnancial statements in the banking sector.
Terefore, the absence of investors’ confdence in the reported earnings
infuence the fnancial market because investors are major players in
ensuring availability of capital to support the economic system. Given
the above state, this study seeks to assess the efect of audit quality
on earnings management in Nigerian listed deposit money banks.
Te broad objective of this study is to identify relationship between
audit quality and earnings management of Nigerian listed money
deposit banks while to assess relationship among joint audit, auditor
specialization, auditor independence and audit tenure on the earnings
management in the listed deposit money banks in Nigeria would need
to established.

Abstract
The incessant failure of Nigerian deposit money banks has raised queries on audit quality in the Nigerian banking
sector. Hence, the study examined relationship between Audit Quality and Earnings Management in Nigerian listed
deposit money banks. The study adopted a longitudinal research design and secondary data covering a period
of 2005-2014 were collected. The population of the study comprised ffteen (15) deposit money banks listed on
Nigerian Stock Exchange as at 2016, out of which six (6) banks were randomly selected resulting in 60 observations.
Panel data technique was employed, while fxed and random effects model were used for estimation. Descriptive
Statistics, Pearson correlation coeffcient and simple pooled OLS regression analysis were used for analysis to
determine possible link between the variables identifed. The results of the study showed that a signifcant positive
relationship existed between joint audit and earnings management (β1=1.054533; t=2.34; and p=0.0023<0.05),
which implies that a change to joint audit from single audit increases earnings management. Also, a signifcant
negative relationship existed between audit specialization and earnings management (β2=-0.0302366; t=-2.07;
and p=0.043<0.05), which implies that every unit increase in audit specialization decreases earnings management.
Furthermore, a signifcant positive relationship existed between audit independence and earnings management
(β4=is 0.6010025; t=4.96; p-value at 0.008<0.05). However, there was an insignifcant negative relationship between
audit tenure and earnings management (β2=-0.0078915; t=-0.12; p=0.906>0.05). The study concluded that lengthy
audit tenures were mechanisms adopted by banks’ managers to infuence auditors’ objectivity in the course of audit
assignment. Therefore, the study recommended that lengthy audit tenure be discouraged.
