future obligations of the business. The retained earnings of the business for the year 2017 has
significantly increased in comparison to previous year analysis and the same is shown to be $
121,444,000. The estimate which is shown for 2015 is $ 38,027,000. Therefore, there is a general

5
CORPORATE ACCOUNTING
structure of the business. The reserves of the business are shown in negative which represents
accumulated losses of the business which are from previous year.
On the other hand, the components of owner’s equity which is shown in the annual report
of the business for 2017 is shown to be equity share capital of the business, share premium,
retained earnings and reserves. The equity share capital which is shown for the business for 2017
comprises of equity capital of Rio Tinto Plc and Rio Tinto Limited. The equity capital represents
the funds which are used by the business for the purpose of meeting the obligations of the
business. The reserves figure which is shown in the balance sheet of the business is shown to be
positive which represents that the business has accumulated parts of earnings which the
management of the company can use in any manner possible (Chambers 2014). The share capital
of the business is shown to be US$ 4,140 million which has significantly improved in
comparison to previous year. This is due to the fact that the company has issued certain number
of shares during the year in order to draw capital from the same (Warren, Reeve and Duchac
2013). The retained earnings of the business are shown to be US$ 23,761 million. The retained
earnings of the business have also increased which is due to increase in profit generating

shown to be more relying on equity capital rather than debt capital of the business. The debt
capital is shown to be $ 385,815,000 for the year 2017 and the same was $ 395,019,000 in 2016

6
CORPORATE ACCOUNTING
business has increased equity capital of the business during the year as shown in the balance
sheet of the business. The borrowings of the business for the year 2015 is shown to be $
407,307,000 which is higher than 2016 estimate. The analysis for 3 years reveals that the
management is systematically reducing the debts of the business and thereby focusing on
application of more equity capital of the business.
In the case of Rio Tinto Ltd, the balance sheet of the company for the year 2017 shows
that the borrowings of the business are US$ 15,148 million which is lower than the estimate
which is shown for the year 2016 which is US$ 17,470 million. The borrowings of the business
for the year 2015 is shown to be US$ 21,140 million which is more than debt capital which is
shown for 2016. This shows that the management of the company is trying to reduce the debt
capital of the business on year by year basis (Ampenberger et al. 2013). The company has also
equity capital which is shown in the annual reports of the business during the year which is
shown to be US$ 4,140 million for 2017 and the same was US$ 3,950 million in 2015 which
shows that the management of the company is trying to increase the equity capital in the capital
structure of the business. The management of Rio Tinto Ltd is trying to increase the equity
capital of the business and is relying more on debt capital of the business.
Therefore, the analysis of the debt and equity capital which is used by both the
companies, it is revealed that the business of Ausdrill ltd is more reliant on using debt capital to
finance the activities of the business while on the other hand the management of Rio Tinto ltd is
relying more on equity capital as the business is trying to reduce the debt capital which is used
by the business. However, in current scenario, the management of Rio Tinto ltd is still using
much more debt capital than equity capital of the business.

includes items such as exchange gains on transaction which are related to foreign operations and
the same is shown to be $ 882,000. There is also an income which the business has received from
joint ventures which are undertaken by the business. In addition to this, gains on revaluation on
financial assets and revaluation gain on property, plant and equipment. As per the annual report

business are exchange gains on translation of foreign operations of the business which is shown
to be $ 882,000. The business has incurred losses on revaluation of assets which are shown in the
annual report of the business during the year. The annual report of Rio Tinto ltd shows actuarial
gains, tax adjustments and adjustment of deferred tax post retirement benefits which are shown
in the annual report of the business during the year (Khan and Bradbury 2014). The
comprehensive income statement prepared also shows hedge cash flow gains and revaluation
gains of avaliable sale securities.
The analysis shows that the items of extraordinary nature are more in case of Rio Tinto
Ltd than in the case of Ausdrill ltd as per the annual reports. In both the cases, if the items are
included in the profit and loss statement, the net profit of the business will either increase or
decrease the income of the business. In the case of Ausdrill ltd, the net profit will decrease if the
comprehensive items are shown in the income statement while on the other hand the profits of
Rio Tinto ltd will increase if profits are included in income statement of the business.
The performance of the business should not be based on comprehensive items which are
shown separately in the annual reports of the business as these items are of extraordinary nature
and might not be recurring in nature. The items which are shown in the comprehensive income
statement are generally of extraordinary nature. Therefore, the items should be included in the
decision-making process of the business.

current and future year. For the computation of cash tax rate, increase in deferred tax liabilities
and deferred tax assets are considered and interest burden which can result in tax savings are
added back. In the computation of Book Tax rate, no such consideration as in case of Cash tax
rate is considered.
