This code shows the process of how we extract text-related features for sample paragraphs. Those features include text statistics, part-of-speech (POS) tags and syntactic structured features over parse trees (parse tree features). It is organised as follows. Section 2 loads libraries and sample paragraphs; section 3 is the process of extracting all textual features and POS tag features and Section 4 shows the process of how to extract parse tree features for each paragraph. Section 5 generates the final output table and the last session provides session information.

In this section, we generate the text related features all textual features, readability, argument features and syntactic features excluding structured synthetics feature over parse trees.
Create a unique index number to record each paragraph. This variable will be used as a key to join other tables. The NLP package requires a large computing power, so running this code using the whole sample size may fail. Given the main purpose of this code is to show the process of generating text-related features, we limit the sample size to 10 paragraphs to ensure the code run smoothly.

This has increased their liquidity risks and made them even more interconnected and systemic. If corporate defaults were to rise, investors and creditor banks may be reluctant to roll over such short-term funding, and so the interbank market could exacerbate financial problems at the banks bearing loan losses.

6 | 2018 | October | The Global Financial Environment | Financial Stability Review – October 2018 | RBA | Much of the run-up in debt in the post-crisis period has been facilitated by the less regulated and less transparent NBFIs. Most of this lending is ultimately funded by the banking sector. While this lending has some benefits, it has allowed banks to circumvent restrictions on lending to riskier sectors and to arbitrage regulatory capital requirements. The riskier nature of the lending, and the obscure and complex interconnections between NBFIs and the banking sector, have led to the build-up of considerable credit, liquidity and contagion risks. Loan losses and defaults have been modest to date. But if they were to escalate, it could result in funding pressures in the non-bank sector, which could cascade through the financial system. | 1_frs | G1 | 1 | 9 | 6 | 1_9_6 | Much of the run-up in debt in the post-crisis period has been facilitated by the less regulated and less transparent NBFIs.

7 | 2016 | October | The Australian Financial System | Financial Stability Review – October 2016 | RBA | The increase in capital ratios over the past year has also been reflected in higher leverage ratios, given that the average risk weight of their assets was largely unchanged. The leverage ratio is a non-risk based measure of a bank’s Tier 1 capital relative to its total exposures, and is intended to be a backstop to the risk-based capital requirements. The leverage ratio framework is yet to be finalised internationally, although the Basel Committee’s governing body agreed the minimum requirement should be 3 per cent and that the leverage ratio should be effective from January 2018. Each of the major banks’ leverage ratios was around 5 per cent at June 2016, well above that minimum. At this level, the major Australian banks’ leverage ratio sits around the median of international banks. | 1_frs | G1 | 1 | 8 | 7 | 1_8_7 | The increase in capital ratios over the past year has also been reflected in higher leverage ratios, given that the average risk weight of their assets was largely unchanged.

8 | 2016 | April | The Global Financial Environment | Financial Stability Review – April 2016 | RBA | Housing market risks are also present in some emerging market and Asian economies. This reflects large increases in residential property prices over recent years – including in Hong Kong, Brazil, Malaysia, Taiwan and Turkey – alongside increased household indebtedness. Price growth has moderated more recently and prices have fallen in some economies, including Brazil, Russia and Taiwan, which could add to the challenges already faced by these economies and their banks from weaker corporate sectors. Housing prices in Hong Kong rose especially quickly until late 2015, partly as a result of low interest rates associated with its fixed exchange rate system. But prices have fallen recently amid concerns about economic conditions in China and slower credit growth. Housing transaction volumes have also fallen, to be at their lowest level since at least the mid 1990s. Despite the slowdown in the housing market, the Hong Kong Monetary Authority imposed a countercyclical capital buffer of 0.625 per cent in January 2016, with further increases scheduled, largely in response to elevated ratios of credit-to-GDP and housing prices-to-rents relative to their long-run trends. | 1_frs | G1 | 1 | 5 | 8 | 1_5_8 | Housing market risks are also present in some emerging market and Asian economies.

9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | Personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit. In recent decades, homeowners have increasingly been able to use housing-secured financing in place of personal debt. In part, this reflects the increased availability and use of redraw facilities and offset accounts linked to residential mortgage loans. More recently, the increased use of buy-now-pay-later services may be contributing to a decline in credit card balances accruing interest. Buy-now-pay-later products are attractive to consumers because they offer the ability to smooth consumption at limited or no cost: these obligations do not incur interest, although late fees are charged if payments are missed and some providers charge regular account keeping or payment processing fees. While these products are not subject to responsible lending laws, the providers do employ some varying methods of managing risk, for example, by setting low purchase limits for new customers or requiring full repayments of previous purchases before funding new purchases. However, there are currently few safeguards that would prevent vulnerable consumers from entering into multiple arrangements with different providers. This could contribute to an increase in financial stress for some households, with lower income and/or younger households potentially more at risk. | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | Personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit.

Direct financial linkages between China and other economies are small in aggregate because China’s capital account is still relatively closed.

6 | 2018 | October | The Global Financial Environment | Financial Stability Review – October 2018 | RBA | Much of the run-up in debt in the post-crisis period has been facilitated by the less regulated and less transparent NBFIs. Most of this lending is ultimately funded by the banking sector. While this lending has some benefits, it has allowed banks to circumvent restrictions on lending to riskier sectors and to arbitrage regulatory capital requirements. The riskier nature of the lending, and the obscure and complex interconnections between NBFIs and the banking sector, have led to the build-up of considerable credit, liquidity and contagion risks. Loan losses and defaults have been modest to date. But if they were to escalate, it could result in funding pressures in the non-bank sector, which could cascade through the financial system. | 1_frs | G1 | 1 | 9 | 6 | 1_9_6 | Much of the run-up in debt in the post-crisis period has been facilitated by the less regulated and less transparent NBFIs.

The leverage ratio is a non-risk based measure of a bank’s Tier 1 capital relative to its total exposures, and is intended to be a backstop to the risk-based capital requirements. The leverage ratio framework is yet to be finalised internationally, although the Basel Committee’s governing body agreed the minimum requirement should be 3 per cent and that the leverage ratio should be effective from January 2018. Each of the major banks’ leverage ratios was around 5 per cent at June 2016, well above that minimum.

8 | 2016 | April | The Global Financial Environment | Financial Stability Review – April 2016 | RBA | Housing market risks are also present in some emerging market and Asian economies. This reflects large increases in residential property prices over recent years – including in Hong Kong, Brazil, Malaysia, Taiwan and Turkey – alongside increased household indebtedness. Price growth has moderated more recently and prices have fallen in some economies, including Brazil, Russia and Taiwan, which could add to the challenges already faced by these economies and their banks from weaker corporate sectors. Housing prices in Hong Kong rose especially quickly until late 2015, partly as a result of low interest rates associated with its fixed exchange rate system. But prices have fallen recently amid concerns about economic conditions in China and slower credit growth. Housing transaction volumes have also fallen, to be at their lowest level since at least the mid 1990s. Despite the slowdown in the housing market, the Hong Kong Monetary Authority imposed a countercyclical capital buffer of 0.625 per cent in January 2016, with further increases scheduled, largely in response to elevated ratios of credit-to-GDP and housing prices-to-rents relative to their long-run trends. | 1_frs | G1 | 1 | 5 | 8 | 1_5_8 | Housing market risks are also present in some emerging market and Asian economies.

9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | Personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit. In recent decades, homeowners have increasingly been able to use housing-secured financing in place of personal debt. In part, this reflects the increased availability and use of redraw facilities and offset accounts linked to residential mortgage loans. More recently, the increased use of buy-now-pay-later services may be contributing to a decline in credit card balances accruing interest. Buy-now-pay-later products are attractive to consumers because they offer the ability to smooth consumption at limited or no cost: these obligations do not incur interest, although late fees are charged if payments are missed and some providers charge regular account keeping or payment processing fees. While these products are not subject to responsible lending laws, the providers do employ some varying methods of managing risk, for example, by setting low purchase limits for new customers or requiring full repayments of previous purchases before funding new purchases. However, there are currently few safeguards that would prevent vulnerable consumers from entering into multiple arrangements with different providers. This could contribute to an increase in financial stress for some households, with lower income and/or younger households potentially more at risk. | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | Personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit.

8 | 2016 | April | The Global Financial Environment | Financial Stability Review – April 2016 | RBA | 1_frs | G1 | 1 | 5 | 8 | 1_5_8 | despite the slowdown in the housing market, the hong kong monetary authority imposed a countercyclical capital buffer of 0.625 per cent in january 2016, with further increases scheduled, largely in response to elevated ratios of credit-to-gdp and housing prices-to-rents relative to their long-run trends. | 7 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit. | 1 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | in recent decades, homeowners have increasingly been able to use housing-secured financing in place of personal debt. | 2 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | in part, this reflects the increased availability and use of redraw facilities and offset accounts linked to residential mortgage loans. | 3 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | more recently, the increased use of buy-now-pay-later services may be contributing to a decline in credit card balances accruing interest. | 4 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | buy-now-pay-later products are attractive to consumers because they offer the ability to smooth consumption at limited or no cost: these obligations do not incur interest, although late fees are charged if payments are missed and some providers charge regular account keeping or payment processing fees. | 5 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | while these products are not subject to responsible lending laws, the providers do employ some varying methods of managing risk, for example, by setting low purchase limits for new customers or requiring full repayments of previous purchases before funding new purchases. | 6 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | however, there are currently few safeguards that would prevent vulnerable consumers from entering into multiple arrangements with different providers. | 7 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | this could contribute to an increase in financial stress for some households, with lower income and/or younger households potentially more at risk. | 8 |
10 | 2016 | April | The Australian Financial System | Financial Stability Review – April 2016 | RBA | 1_frs | G1 | 1 | 2 | 10 | 1_2_10 | australian banks using the irb approach to credit risk have been required to disclose their leverage ratio from mid 2015. | 1 |
10 | 2016 | April | The Australian Financial System | Financial Stability Review – April 2016 | RBA | 1_frs | G1 | 1 | 2 | 10 | 1_2_10 | the leverage ratio is a non-risk-based measure of a bank’s tier 1 capital relative to its total exposures, and is intended to be a backstop to the risk-based capital requirements. | 2 |
10 | 2016 | April | The Australian Financial System | Financial Stability Review – April 2016 | RBA | 1_frs | G1 | 1 | 2 | 10 | 1_2_10 | the leverage ratio framework is yet to be finalised internationally, although the basel committee’s governing body agreed the minimum requirement should be 3 per cent. | 3 |

1 | 2016 | April | The Global Financial Environment | Financial Stability Review – April 2016 | RBA | Along with the increase in shadow lending, banks – especially small and medium-sized banks – have also sourced more funding from the short-term interbank market over recent years. This has increased their liquidity risks and made them even more interconnected and systemic. If corporate defaults were to rise, investors and creditor banks may be reluctant to roll over such short-term funding, and so the interbank market could exacerbate financial problems at the banks bearing loan losses. It could also transmit distress to other institutions that investors consider to have a similar vulnerability. | 1_frs | G1 | 1 | 10 | 1 | 1_10_1 | Along with the increase in shadow lending, banks – especially small and medium-sized banks – have also sourced more funding from the short-term interbank market over recent years.

While net contributions have remained fairly stable in recent years, it is likely that outflows will trend higher relative to contributions as the population ages and more members enter the drawdown phase. Superannuation funds will therefore need to consider the associated liquidity implications. | 1_frs | G1 | 1 | 4 | 2 | 1_4_2 | Total superannuation assets grew at an annualised rate of nearly 5 per cent over the first half of 2016, somewhat below the average pace of recent years, as low bond yields and relatively subdued equity market returns weighed on investment income.

5 | 2016 | April | The Global Financial Environment | Financial Stability Review – April 2016 | RBA | If financial strains that threaten growth in China emerge, they could spill over to other economies by affecting trade volumes and commodity prices, as well as sentiment in global financial markets. Direct financial linkages between China and other economies are small in aggregate because China’s capital account is still relatively closed. But these linkages have grown – both in terms of foreign bank lending to China and Chinese bank lending abroad – and are sizeable for particular jurisdictions, so they could be an additional mechanism for transmitting financial difficulties. | 1_frs | G1 | 1 | 3 | 5 | 1_3_5 | If financial strains that threaten growth in China emerge, they could spill over to other economies by affecting trade volumes and commodity prices, as well as sentiment in global financial markets.

6 | 2018 | October | The Global Financial Environment | Financial Stability Review – October 2018 | RBA | Much of the run-up in debt in the post-crisis period has been facilitated by the less regulated and less transparent NBFIs. Most of this lending is ultimately funded by the banking sector. While this lending has some benefits, it has allowed banks to circumvent restrictions on lending to riskier sectors and to arbitrage regulatory capital requirements. The riskier nature of the lending, and the obscure and complex interconnections between NBFIs and the banking sector, have led to the build-up of considerable credit, liquidity and contagion risks. Loan losses and defaults have been modest to date. But if they were to escalate, it could result in funding pressures in the non-bank sector, which could cascade through the financial system. | 1_frs | G1 | 1 | 9 | 6 | 1_9_6 | Much of the run-up in debt in the post-crisis period has been facilitated by the less regulated and less transparent NBFIs.

7 | 2016 | October | The Australian Financial System | Financial Stability Review – October 2016 | RBA | The increase in capital ratios over the past year has also been reflected in higher leverage ratios, given that the average risk weight of their assets was largely unchanged. The leverage ratio is a non-risk based measure of a bank’s Tier 1 capital relative to its total exposures, and is intended to be a backstop to the risk-based capital requirements. The leverage ratio framework is yet to be finalised internationally, although the Basel Committee’s governing body agreed the minimum requirement should be 3 per cent and that the leverage ratio should be effective from January 2018. Each of the major banks’ leverage ratios was around 5 per cent at June 2016, well above that minimum. At this level, the major Australian banks’ leverage ratio sits around the median of international banks. | 1_frs | G1 | 1 | 8 | 7 | 1_8_7 | The increase in capital ratios over the past year has also been reflected in higher leverage ratios, given that the average risk weight of their assets was largely unchanged.

8 | 2016 | April | The Global Financial Environment | Financial Stability Review – April 2016 | RBA | Housing market risks are also present in some emerging market and Asian economies. This reflects large increases in residential property prices over recent years – including in Hong Kong, Brazil, Malaysia, Taiwan and Turkey – alongside increased household indebtedness. Price growth has moderated more recently and prices have fallen in some economies, including Brazil, Russia and Taiwan, which could add to the challenges already faced by these economies and their banks from weaker corporate sectors. Housing prices in Hong Kong rose especially quickly until late 2015, partly as a result of low interest rates associated with its fixed exchange rate system. But prices have fallen recently amid concerns about economic conditions in China and slower credit growth. Housing transaction volumes have also fallen, to be at their lowest level since at least the mid 1990s. Despite the slowdown in the housing market, the Hong Kong Monetary Authority imposed a countercyclical capital buffer of 0.625 per cent in January 2016, with further increases scheduled, largely in response to elevated ratios of credit-to-GDP and housing prices-to-rents relative to their long-run trends. | 1_frs | G1 | 1 | 5 | 8 | 1_5_8 | Housing market risks are also present in some emerging market and Asian economies.

9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | Personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit. In recent decades, homeowners have increasingly been able to use housing-secured financing in place of personal debt. In part, this reflects the increased availability and use of redraw facilities and offset accounts linked to residential mortgage loans. More recently, the increased use of buy-now-pay-later services may be contributing to a decline in credit card balances accruing interest. Buy-now-pay-later products are attractive to consumers because they offer the ability to smooth consumption at limited or no cost: these obligations do not incur interest, although late fees are charged if payments are missed and some providers charge regular account keeping or payment processing fees. While these products are not subject to responsible lending laws, the providers do employ some varying methods of managing risk, for example, by setting low purchase limits for new customers or requiring full repayments of previous purchases before funding new purchases. However, there are currently few safeguards that would prevent vulnerable consumers from entering into multiple arrangements with different providers. This could contribute to an increase in financial stress for some households, with lower income and/or younger households potentially more at risk. | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | Personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit.

1 | 2016 | April | The Global Financial Environment | Financial Stability Review – April 2016 | RBA | Along with the increase in shadow lending, banks – especially small and medium-sized banks – have also sourced more funding from the short-term interbank market over recent years. This has increased their liquidity risks and made them even more interconnected and systemic. If corporate defaults were to rise, investors and creditor banks may be reluctant to roll over such short-term funding, and so the interbank market could exacerbate financial problems at the banks bearing loan losses. It could also transmit distress to other institutions that investors consider to have a similar vulnerability. | 1_frs | G1 | 1 | 10 | 1 | 1_10_1 | Along with the increase in shadow lending, banks – especially small and medium-sized banks – have also sourced more funding from the short-term interbank market over recent years.

Direct financial linkages between China and other economies are small in aggregate because China’s capital account is still relatively closed.

6 | 2018 | October | The Global Financial Environment | Financial Stability Review – October 2018 | RBA | Much of the run-up in debt in the post-crisis period has been facilitated by the less regulated and less transparent NBFIs. Most of this lending is ultimately funded by the banking sector. While this lending has some benefits, it has allowed banks to circumvent restrictions on lending to riskier sectors and to arbitrage regulatory capital requirements. The riskier nature of the lending, and the obscure and complex interconnections between NBFIs and the banking sector, have led to the build-up of considerable credit, liquidity and contagion risks. Loan losses and defaults have been modest to date. But if they were to escalate, it could result in funding pressures in the non-bank sector, which could cascade through the financial system. | 1_frs | G1 | 1 | 9 | 6 | 1_9_6 | Much of the run-up in debt in the post-crisis period has been facilitated by the less regulated and less transparent NBFIs.

The leverage ratio is a non-risk based measure of a bank’s Tier 1 capital relative to its total exposures, and is intended to be a backstop to the risk-based capital requirements. The leverage ratio framework is yet to be finalised internationally, although the Basel Committee’s governing body agreed the minimum requirement should be 3 per cent and that the leverage ratio should be effective from January 2018. Each of the major banks’ leverage ratios was around 5 per cent at June 2016, well above that minimum. At this level, the major Australian banks’ leverage ratio sits around the median of international banks. | 1_frs | G1 | 1 | 8 | 7 | 1_8_7 | The increase in capital ratios over the past year has also been reflected in higher leverage ratios, given that the average risk weight of their assets was largely unchanged.

8 | 2016 | April | The Global Financial Environment | Financial Stability Review – April 2016 | RBA | Housing market risks are also present in some emerging market and Asian economies. This reflects large increases in residential property prices over recent years – including in Hong Kong, Brazil, Malaysia, Taiwan and Turkey – alongside increased household indebtedness. Price growth has moderated more recently and prices have fallen in some economies, including Brazil, Russia and Taiwan, which could add to the challenges already faced by these economies and their banks from weaker corporate sectors. Housing prices in Hong Kong rose especially quickly until late 2015, partly as a result of low interest rates associated with its fixed exchange rate system. But prices have fallen recently amid concerns about economic conditions in China and slower credit growth. Housing transaction volumes have also fallen, to be at their lowest level since at least the mid 1990s. Despite the slowdown in the housing market, the Hong Kong Monetary Authority imposed a countercyclical capital buffer of 0.625 per cent in January 2016, with further increases scheduled, largely in response to elevated ratios of credit-to-GDP and housing prices-to-rents relative to their long-run trends. | 1_frs | G1 | 1 | 5 | 8 | 1_5_8 | Housing market risks are also present in some emerging market and Asian economies.

Despite the slowdown in the housing market, the Hong Kong Monetary Authority imposed a countercyclical capital buffer of 0.625 per cent in January 2016, with further increases scheduled, largely in response to elevated ratios of credit-to-GDP and housing prices-to-rents relative to their long-run trends. | 176 | 8 | 324 | 33 | 14.71273 | 28.76409 | 11 | 15 | 16 | 8 | 8 | 11 | 27 | 24 | 2 | 1 | 36 | 21 | 0 | 4 | 9 | 1 | 4 | 2 | 1 | 4 | 9 | 4 | 2 | 1 | 4 | 0 | 0 | 0 | 2 | 1 | 0 | 4.49 | 6.18 | 15.17 | 13.48 | 1.12 | 0.56 | 20.22 | 11.80 | 0.00 | 2.25 | 5.06 | 0.56 | 2.25 | 1.12 | 0.56 | 2.25 | 5.06 | 2.25 | 1.12 | 0.56 | 2.25 | 0.00 | 0.00 | 0.00 | 1.12 | 0.56 | 0.00 | housing | NN | housing | NN | market | NN | risks | NNS | 0 | 1 | 1 | 0 | 0 | 0 | 1 | 1 | 0 | 1 | 1 | 1 | 1 | 0 | 0 | 0 | 4 | 0 | 0 | 1 | 1 | 4 | 1 | 1 | 0 | 1 | 0 | 1 | 1 | 19 | 9 | 1 | 0 | 2 | 0 | 2 | 9 | 64 | 29 | 11 | 1 | 20 | 1 |
9 | 2019 | October | Household and Business Finances | Financial Stability Review – October 2019 | RBA | Personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit. In recent decades, homeowners have increasingly been able to use housing-secured financing in place of personal debt. In part, this reflects the increased availability and use of redraw facilities and offset accounts linked to residential mortgage loans. More recently, the increased use of buy-now-pay-later services may be contributing to a decline in credit card balances accruing interest. Buy-now-pay-later products are attractive to consumers because they offer the ability to smooth consumption at limited or no cost: these obligations do not incur interest, although late fees are charged if payments are missed and some providers charge regular account keeping or payment processing fees. While these products are not subject to responsible lending laws, the providers do employ some varying methods of managing risk, for example, by setting low purchase limits for new customers or requiring full repayments of previous purchases before funding new purchases. However, there are currently few safeguards that would prevent vulnerable consumers from entering into multiple arrangements with different providers. This could contribute to an increase in financial stress for some households, with lower income and/or younger households potentially more at risk. | 1_frs | G1 | 1 | 6 | 9 | 1_6_9 | Personal debt, which includes personal loans, credit card debt and other revolving credit such as margin loans, accounts for a small and declining share of household credit.

10 | 2016 | April | The Australian Financial System | Financial Stability Review – April 2016 | RBA | Australian banks using the IRB approach to credit risk have been required to disclose their leverage ratio from mid 2015. The leverage ratio is a non-risk-based measure of a bank’s Tier 1 capital relative to its total exposures, and is intended to be a backstop to the risk-based capital requirements. The leverage ratio framework is yet to be finalised internationally, although the Basel Committee’s governing body agreed the minimum requirement should be 3 per cent. The Basel Committee is expected to make final adjustments to the measure by the end of 2016, with a view to establishing the requirement from January 2018. Each of the Australian banks required to disclose the measure reported a leverage ratio close to 5 per cent at December 2015, well above the minimum. | 1_frs | G1 | 1 | 2 | 10 | 1_2_10 | Australian banks using the IRB approach to credit risk have been required to disclose their leverage ratio from mid 2015.
