Economic perspectives
Annual address by Governor Svein Gjedrem at the meeting of the Supervisory Council of Norges Bank on 19 February 2004
Introduction
There is now growth in the Norwegian economy. Oil prices are high. Capacity utilisation in the mainland economy is at the level prevailing in the mid-1990s. Wage growth is slowing. White-collar workers have lowered their wage demands, and there are prospects of a moderate main settlement this spring - the first in eight years. The value of the krone is on a par with the mid-1990 level. The interest rate level is in line with the level among our trading partners.
In that respect, there is equilibrium in the Norwegian economy at present.
But it is fragile.
The international division of labour is shifting, and when faced with major changes it is a disadvantage for Norwegian business and industry that costs are high.
Inflation is very low.
Short-term interest rates abroad have been unusually low over the past 2½ years, and there are no prospects of a considerable increase in the near term even if the world economy is expanding. Last year, interest rates abroad acted as a magnet on Norwegian interest rates. We now have the lowest nominal interest rate level recorded in decades.
Norwegian households are optimistic and are borrowing and investing in housing and property.
This stands in contrast to corporate behaviour. Businesses are rationalising and earnings are on the rise, but they are still investing and borrowing on a limited scale.
The upturn is still not entirely self-sustained.
A global financial market
Cross-border capital flows have increased considerably in recent decades. Bond markets have moved more in tandem, particularly since the mid-1990s. This also applies to equity markets.
Investors are increasingly spreading their investments across countries. They are diversifying risk, and seeking high returns. In parallel, governments, banks and companies are issuing more debt externally.
Currency trading has increased markedly since the 1980s. This trend was reversed when the number of currencies was reduced owing to the introduction of the euro. Large trading volumes enhance market liquidity. The growth in currency trading is ascribable to an increase in portfolio investment, higher foreign direct investment and growth in world trade.
The forward exchange and options market have expanded in recent years. A deeper market reduces transaction costs, and it is easier to find counterparties. This has provided companies with greater scope for hedging against foreign exchange risk. The use of instruments that reduce the risk associated with a floating krone is also increasing in Norway.
A considerably larger portion of credit in other countries is now channelled via the bond market. Less risk is being accumulated in banking systems. The development of new markets and instruments, for example credit derivatives, has also led to a broader risk spread than earlier.
The improved diversification of risk is probably one of the reasons that world financial markets have coped with the stock market decline and the accounting scandals with limited damage to the wider economy. This is probably one reason why the downturn following the stock market decline in 2000 was considerably less pronounced than earlier downturns.
The new instruments spread risk, but do not eliminate it. Financial markets have become highly complex. This alone entails an operational risk, which is a challenge to participants and the supervisory authorities.
A shift in the international division of labour
Increased trade promotes growth and lays a basis for prosperity. A number of Asian countries have experienced strong, export-led growth - Japan from the 1950s and several countries in Southeast Asia from the 1960s.
In recent years, China has become an important player in international trade, and the country is now probably the world's fourth largest trade nation. The Asian economies and the rest of the world have become more integrated.
Technological advances and a sharp fall in prices in the IT and telecommunications sectors have exposed a number of services that were previously sheltered to competition from low- cost countries. Indian companies service three million customer telephones for companies in the US and the UK - daily. European airlines are transferring ticket settlement to India. US companies are outsourcing accounting services to India. Analytical activity in investment banks and development divisions in ITC companies are also being moved to India. Norwegian engineering companies are buying cheap engineering services in India and China.
EU enlargement this spring, with ten new members, is also influencing the division of labour in Europe.
The advances in Asian economies have generally relied on an abundant supply of cheap labour, but wages have gradually increased in step with productivity gains. A higher income level paves the way for higher imports.
Today's globalisation has a historical parallel.
In the period preceding World War I, the world experienced a period of strong growth in trade and cross-border capital flows. There were few political barriers and major technological advances fostered growth in trade. Prosperity increased. But this period was interrupted, and in the interwar period protectionism gained ground, with trade barriers and a contraction in international trade. This was combined with an economic recession. In the post-war period, trade barriers have gradually been scaled back. Trade picked up already in the 1950s, and since the 1980s financial markets have become evermore interwoven.
Implications for the Norwegian economy
Intensified competition from Japanese and Korean shipyards had serious implications for Norwegian shipbuilding in the 1970s and 1980s. However, Japan has also become an important market for Norwegian products. From the considerable deficits of earlier years, trade in traditional goods with Japan has moved into near balance.
Strong growth in Asia is probably one of the prominent factors contributing to high oil prices in spite of low growth in the OECD area in recent years. China accounted for close to 50 per cent of growth in world oil consumption in 2002 and 2003. Trade in Asia has stimulated Norwegian shipping.
The Chinese economy could continue to expand at a brisk pace for a longer period, which would open a large market that can also be entered by Norwegian enterprises. Norwegian exports to China have increased, but are still limited.
Over several years, enterprises in Central European countries have been a source of competition for Norwegian jobs. Integration is also opening new markets and providing new sources of income for Norwegian enterprises. At the same time, tender requirements and the freedom of establishment have increased the competition facing Norwegian industries that were previously sheltered.
A steadily larger share of Norway's consumer goods imports come from China and Central European countries. Growth in imports from China was provided with an additional impetus after China became a member of the World Trade Organization in 2001. Imports from Eastern Europe have also continued to grow.
There are many economic agents in Norway that are benefiting from globalisation. Consumers are enjoying lower prices for goods and services. Input prices have fallen and companies can sell their products in new markets. But there are also costs. Norwegian businesses and jobs may lose in the competition.
The challenge lies in moving idle resources to new business activities. This requires adaptability and a sound cost policy.
Monetary policy
The operational target of monetary policy, as defined by the Government, is inflation of 2½ per cent over time. The target is symmetrical - it is just as important to avoid an inflation rate that is too low as an inflation rate that is too high. The inflation target provides economic agents with an anchor for inflation expectations.
History shows that there is no long-term trade-off between lower unemployment or stronger economic growth and higher inflation. We witnessed this in the 1980s when growth was low and inflation high. The task of monetary policy is to provide a nominal anchor. Low and stable inflation is such an anchor.
Why is a little inflation an advantage?
There are several reasons why it is an advantage for inflation to be higher than zero.
The structure of the economy is in flux. Demand for labour with different qualifications is changing. This requires changes in relative wages. There are rigidities in nominal wage growth. Nominal wages do not readily fall. With some inflation, relative wages can change without a fall in nominal wages. There may also be rigidities in the pricing of goods and services. Some degree of inflation will thus oil the economic machinery.
In periods, inflation and economic growth will be low. It is then appropriate for real interest rates to be low, or even negative. Nominal interest rates cannot be set below zero. If inflation becomes entrenched at a low level or near zero, the interest rate will be less effective as an instrument.
There are different ways of measuring inflation. The consumer price index tends to overestimate actual inflation. The most important source of measurement errors is probably the difficulty of distinguishing between changes in the quality and price of goods. In other countries, findings show that the consumer price index overestimates actual inflation to the order of ½ -1 percentage point.
The conduct of monetary policy
Norges Bank normally sets the interest rate with a view to attaining an inflation rate of 2½ per cent two years ahead. If demand for goods and services is high and there is a shortage of labour, there will normally be prospects of higher inflation. When the interest rate is raised, demand is dampened and inflation is kept in check. If demand is low and unemployment rises, there will be prospects of lower inflation. The interest rate will then be lowered. The inflation target thus represents a framework, not an obstacle, for monetary policy to contribute to stability in output and employment.
In the long run, output is determined by the supply of labour and capital and adaptability, but in the short and medium term monetary policy can also have an impact on the real economy.
Norges Bank operates a flexible inflation targeting regime, so that weight is given to variability in output and employment and inflation. The economy grows over time. Output will in periods lie below trend growth and in others above trend. Stabilising output growth means that one seeks to maintain actual output near trend.
Monetary policy credibility
Expectations play an important role in price and wage formation. Expectations concerning inflation and economic stability are of crucial importance for the foreign exchange market. Inflation expectations also influence wage demands and pricing in the business sector.
With confidence in monetary policy, expected inflation in the long term will be close to the inflation target. This alone contributes to stabilising inflation.
Surveys indicate that enterprises, the social partners and other economic agents expect inflation to be 2½ per cent over time. Financial market participants also expect that inflation will be 2½ per cent ahead, as implied by long-term bond yields.
A flexible exchange rate
The krone exchange rate is an important channel for monetary policy.
The krone fluctuates. This is not surprising because other countries' currencies also fluctuate. The krone exchange rate is the price of our currency measured in a foreign currency. Developments in other countries are just as important for the krone as developments in the Norwegian economy. Capital flows freely and flows can change rapidly. This can spill over to exchange rates and interest rates as well as output and employment.
A structural feature of open economies like the Norwegian economy - with a national currency - is that the exchange rate fluctuates.
The Norwegian krone does not stand out as particularly unstable. On the contrary, in countries like Sweden, the UK, Switzerland, Australia, Canada and New Zealand, the exchange rate fluctuates just as much - or more - than in Norway.
There is a cost involved for businesses in hedging against fluctuations in the krone. A krone that is stable - but too strong - also entails costs in the form of low activity. Similarly, a krone that is stable - but weak - is a source of high inflation.
Petroleum revenues generally provide substantial, but uneven currency inflows into Norway. The currency flows might have resulted in a strong krone and large variations in the exchange rate. This tendency is countered when the annual use of petroleum revenues over the central government budget is predictable and independent of annual revenue inflows, and the remainder is invested abroad. The capital outflow through the Petroleum Fund contributes to both curbing the appreciation of the krone and maintaining its stability.
Norges Bank has not defined an exchange rate target. Nevertheless, developments in the krone are of considerable importance to interest-rate setting because exchange rate developments have an impact on inflation and output. When there are prospects of moderate economic activity, low wage growth and low inflation, Norges Bank will reduce the interest rate. This will normally result in a depreciation of the krone. Prices for imported goods and services will increase. A weaker krone strengthens the competitiveness of Norwegian enterprises and indirectly leads to higher output, employment and inflation.
Themes in foreign exchange markets shift. In periods, investor focus on stock returns feeds through to exchange rate movements. During periods of political and economic unrest, investors may choose individual currencies as a safe haven - often the Swiss franc. In the autumn of 2002, the Norwegian krone was probably also perceived as a safe haven. Wide fluctuations between major currencies have a tendency to result in a weaker krone. In the past 12-18 months, developments in the interest rate differential between Norway and other countries appear to have had a particularly marked impact on our currency. Norwegian interest rates have been pushed down to the level prevailing abroad.
In the autumn of 2003, the krone showed a tendency to appreciate against the euro. This partly reflected lowered market expectations concerning an interest rate increase abroad and expectations that interest rates might rise earlier in Norway than in other countries. At the same time, the euro appreciated in relation to other currencies. Changes in the krone resulted in an unintended tightening of monetary policy. This trend was reversed in December owing to a reduction in interest rates and low inflation figures. The interest rate reduction was probably of considerable importance as it eliminated the excess return on NOK investments. Today, the krone is at a level that is more consistent with the objective of promoting stability in output and employment. The weaker krone will contribute to a rise in inflation from a level that is too low.
Normally, Norges Bank will not intervene in the foreign exchange market in order to influence the exchange rate. Exchange market intervention, whether it be purchases or sales of foreign exchange, is not an appropriate instrument for influencing the krone over a longer period. We do not wish to act in a way that may trigger a game situation in the foreign exchange market. Foreign exchange intervention rather than a change in the interest rate may give ambiguous signals to foreign exchange operators and a game situation may arise.
Although the krone may fluctuate in the short term, it will generally stabilise over time. When inflation has been higher in Norway than among our trading partners for a longer period, the krone has generally depreciated. When inflation in Norway is expected to be broadly in line with that of other countries, the exchange rate will normally also return to its normal range following periods when the krone has been particularly strong or particularly weak. This provides a basis for stable exchange rate expectations.
The advantage of a flexible exchange rate is perhaps most evident when the economy is sluggish. If the krone were to remain at a level that is too strong, nominal wages would have to remain unchanged over a longer period or fall in order to bolster companies and jobs. This only occurs when unemployment is very high. With a flexible exchange rate, a depreciation of the krone can also boost competitiveness. A flexible exchange rate can reduce fluctuations in employment and output.
Empirical studies do not provide any evidence that floating exchange rates have reduced growth in industrial countries. Rather, they suggest that industrial countries with floating exchange rates have fared well, and often better, than countries with an exchange rate target. A precondition is that there is an economic policy framework so that inflation does not spin out of control.
Economic developments and prospects
External cyclical developments and events have had considerable implications for developments in the Norwegian economy.
The US fuelled the international upswing in the 1990s, with strong growth in private consumption, rising equity prices and a high level of investment. Inflation was low because productivity increased.
In Continental Europe, the upturn started later and was weaker. Capacity utilisation in Germany and France was low through most of the 1990s.
The international upturn came to a halt in 2000. The bubbles in the equity markets burst. Many years of high investment led to excess capacity, and rising unemployment. The terrorist attacks on 11 September 2001 put a new damper on economic activity. From the summer of 2002 to the spring of 2003, a highly extraordinary accumulation of negative events in the global community - accounting scandals, fear of terror, war and disease - put a brake on growth. US interest rates, which were sharply reduced at the beginning of the downturn, have subsequently been reduced further. Interest rates have also remained low in the euro area.
There are now clear signs that the global economy has passed the trough. However, while the outlook is brighter, price inflation is still low and interest rates are being kept unusually low. Economic growth is high again in the US. Employment is rising, but there is still excess production capacity and very low inflation. It may take some time before interest rates are increased substantially in the US. Growth in Asia is solid, but a global rise in interest rates is unlikely to start there.
Inflation is higher in the euro area than in the US and approximately in line with the objective defined by the European Central Bank. In the euro area, however, capacity utilisation is very low, unemployment high and the outlook for growth is weaker. Against this background, it will probably also take time before interest rates rise markedly in the euro area.
The imbalances in world trade represent a particular risk. The US is running a substantial trade deficit, which was financed for a number of years by private capital flows to the US business sector. The flows have subsided and led to a sharp fall in the US dollar at the same time as the euro has appreciated. Through purchases of US government securities, Asian countries have thus far kept their currencies stable against the US dollar.
The US federal budget deficit is an important source of the imbalances in world trade. It appears that it will take time before the deficit is reduced to a considerable extent. This entails a risk that the dollar will depreciate further and that US long-term government bond yields will move up. Growth in Continental Europe, which is highly reliant on impetus from exports, may weaken markedly if the dollar continues to fall.
Norway, like other countries, experienced a period of strong expansion in the 1990s. The expansion in Norway lasted considerably longer than in other countries. In 1998, the economy shifted from an upturn with high growth rates to an expansion with lower growth but low unemployment, labour shortages in many sectors and strong growth in labour costs.
Wage developments culminated in the spring of 2002 and the expansion was reversed in the second half of the year. Growth came to a halt and employment fell. A number of factors triggered this development. Higher wage costs weakened the purchasing power of public entities. Global stagnation had a dampening impact on Norwegian exports. In Norway, the interest rate was kept high after the wage settlement and a persistent, unexpected low level of interest rates abroad resulted in a strong krone. The sharp rise in electricity prices last winter also affected the domestic economy.
Consumer price inflation in Norway declined sharply through 2003. A number of factors appear to have contributed to the decline.
The appreciation of the krone through 2002 pushed down import price inflation.
A change in trade patterns and external economic conditions have resulted in an unexpectedly sharp fall in import prices, even when measured in terms of what Norwegian importers pay in foreign currency.
The change in trade patterns has made a considerable contribution to the sharp decline in prices for clothing, shoes and audiovisual equipment. Rapid technological advances have also pushed down prices for audiovisual equipment.
In Norway, competition has probably increased in the retail industry and other service sectors in recent years. Initially, heightened competition affects companies' profit margins. But enterprises will respond by reducing their costs. This will occur in part in the individual enterprise, but subcontractors will also be required to reduce their prices and enhance efficiency. Therefore, increased competition usually triggers higher productivity growth in the economy. Low inflation may therefore be matched by growth in productivity.
The cyclical downturn last winter, low wage increases last year, fiscal discipline, an unexpected decline in inflation and prospects of low inflation have resulted in a considerable easing of monetary policy. The interest rate has been reduced by 5 percentage points and is now approximately the same as among our trading partners. The krone has depreciated by about 12 per cent over the past year, and has returned to the level prevailing in the summer of 2001 and is in line with the average for the 1990s.
Monetary policy is expansionary now. This is reflected in low after-tax real interest rates. A long-term real yield on 10-year bonds can be estimated at about 1 per cent. We have adjusted the nominal interest rate for expected inflation. The short-term real interest rate is estimated at 1½ per cent. We have then adjusted the figure for actual inflation. The fall in nominal interest rates in 2003 has also reduced household net interest expenses. This has increased household purchasing power considerably.
The fall in the value of the krone over the past year has strengthened the Norwegian business sector. The business sector is, however, still feeling the effects of a sharp rise in labour costs over a period of several years. Relative labour costs measured in a common currency are in line with the level prevailing in 1990, but approximately 10 per cent higher than in the mid- 1990s. The internationally exposed sector has been scaled back. Those companies that are currently operating may be in a better position to bear the high wage level. Nevertheless, costs may limit activity and employment.
Growth in the Norwegian economy picked up again through the summer of 2003. In the period ahead, solid growth in household income, subdued consumer price inflation and low interest rates will provide the conditions for high growth in private consumption. There is optimism in the building and construction sector. High petroleum investment is also supporting activity while mainland business investment has been low for a long period.
The number of persons employed began to increase in the summer of 2003 and unemployment stabilised.
An economic turnaround has occurred, with a soft landing after the long period of high cost inflation in Norway and a low level of activity in other countries.
But inflation is too low.
As mentioned, there are three main factors that have contributed to this.
First, the global downturn had considerable implications for the impact of interest-rate setting in Norway. A strong krone contributed to the decline in inflation. The krone has now returned to its previous level so that the effect will be reversed.
Second, low inflation in other countries and rapid changes in the international division of labour have resulted in a fall in prices for imported goods and services, even when measured in terms of what Norwegian importers pay in foreign currency.
Third, intensified domestic competition also appears to have exerted downward pressure on prices.
As a result of both changes in the international division of labour and increased domestic competition, there is idle labour and available real capital in Norway. We cannot rule out that adjustments will be made over a period of time and that these adjustments will encompass a large portion of the domestic economy. Thus, it is possible that the level of output that is consistent with stable inflation will increase.
Inflation will remain low in 2004. However, the easing of monetary policy will gradually push up inflation. As mentioned, it may take some time before interest rates in other countries are increased to a considerable extent. We have seen that in periods, the krone is heavily influenced by changes in the difference between interest rates at home and abroad, and we must take this into account when setting interest rates. Themes in foreign exchange markets may shift, however. The impact of interest rate changes on the exchange rate may be less pronounced.
When inflation gradually moves up from a very low level, there will be a basis for gradually moving towards a more normal short-term interest rate level in Norway. This may counter the emergence of excessive pressures on domestic resources in the medium term. Interest rate developments in other countries may also have considerable impact on the krone and hence on Norwegian interest rates.
When inflation is low - and as low as it is now - it is appropriate to place considerable emphasis on pushing up inflation. Therefore, we are particularly vigilant with regard to consumer price developments.
Financial stability
Developments in real economic variables are mirrored in credit markets.
In recent years, household income has shown solid growth, and household confidence has been high. However, corporate earnings have been low, and until recently enterprises have primarily focused on enhancing efficiency.
Credit developments are giving ambiguous signals to our interest-rate setting. Growth in household borrowing is high, but enterprises are reducing debt. The change in the breakdown of credit may have been amplified by banks' increased eagerness to extend credit to households after a period of losses on loans to the business sector. Total credit is expanding broadly in line with normal growth in nominal GDP.
Developments in credit to enterprises shadow developments in their investments. Low credit growth indicates that mainland business investment has not yet picked up.
Household debt has increased sharply since 1999. Developments in debt in the 1990s may partly be interpreted as a delayed adaptation to the deregulation of the housing and credit markets in the 1980s after many households experienced financial difficulties following the relaxation.
Moreover, there now seems to be a tendency towards investing in property and incurring loans at a more mature age so that younger generations not only inherit dwellings, but debt as well. Both debt and wealth are on the rise for these more mature age groups.
Household credit demand is closely linked to developments in the housing market.
House prices have risen by an average of around 9 per cent over the past 10 years. High and persistent house price inflation can contribute to holding up credit growth even after prices have levelled off. Since only a portion of the housing stock is sold each year, some dwellings will be sold at a higher price than they were last sold for a long period. This is one of the reasons why growth in credit to households has remained high even after house price inflation moderated in 2002 and into 2003.
Home-owners who have seen the value of their dwellings rise have the possibility of taking up new mortgage-secured loans. They free up a portion of their home equity value to finance consumption and other investments.
It is easiest to sell dwellings in the largest cities and some specific areas are particularly attractive. Residential property is now a fairly liquid and attractive investment.
Price developments in the housing market are characterised by the fact that there is little change in the housing stock from one year to the next. As a result, higher demand for housing will in the first round translate into higher prices. Housing prices fluctuate more than prices for goods and services, where supply can be rapidly adapted.
A persistently high rate of increase in house prices can in isolation engender expectations of a further rise and can thus prove to be self-reinforcing for a period.
Norwegian households generally finance their mortgages at an interest rate that follows the short-term money market rate. Floating interest rates tend to vary widely over time.
The interest rate level is very low at present, and long-term investments cannot rely on this interest rate spanning the life of a housing loan. According to money market expectations, the interest rate will eventually stabilise around 5½ per cent. This is consistent with an inflation target of 2½ per cent and a long-term real interest rate in line with the level abroad. This interest rate, with a mark-up for banks' margins, provides a more realistic expression of the interest rate level that will apply over the loan's life than the floating interest rate prevailing today.
It may prove to be particularly challenging for borrowers to assess their debt-servicing capacity over time at a time when the interest rate is abnormally low. Such a low interest rate also places particular demands on banks in assessing the creditworthiness of borrowers. But experience has shown that the underlying cause of loans defaults can be overly optimistic assessments on the part of both the lender and borrower.
House prices and developments in household credit influence consumption and housing investment. We seek to take account of these indirect effects in interest-rate setting.
A sharp rise in asset prices and debt accumulation may pose a risk to economic stability. With a view to mitigating this risk, it will be appropriate in some situations to apply a somewhat longer-than-normal time horizon than two years to attain the inflation target.
However, at present debt accumulation is high only in the household sector. Enterprises are accumulating little debt. House prices are rising, but non-residential property prices are stable.
The debt to income ratio is now in line with the level recorded at the beginning of the 1990s.
We have limited scope for restraining structural changes that occur when households increase their debt over several years to invest in housing and other property and assets. An interest rate that would effectively restrain these structural adjustments would also have an adverse impact on output and employment.
The interest rate can be used to reduce credit demand. At present - with low interest rates abroad and a close link between domestic interest rates and the krone - a tighter monetary policy would restrain credit demand primarily because job security would be reduced.
A flexible inflation targeting regime reduces the possibility of exposing households to a double shock in the form of higher unemployment and higher interest rates, as was the case prior to the banking crisis in the beginning of the 1990s. If the economy is exposed to disturbances that lead to higher unemployment, inflation will normally decline and interest rates be lowered.
Conclusion
To sum up:
The operational target of monetary policy is inflation of close to 2½ per cent over time. Norges Bank operates a flexible inflation targeting regime, so that weight is given to variability in output and employment and inflation.
Norges Bank has not defined an exchange rate target. A flexible exchange rate enhances stability in output and employment.
A structural feature of open economies like the Norwegian economy - with a national currency - is that the exchange rate fluctuates. The forward exchange and options markets have provided companies with greater scope for hedging against foreign exchange risk.
An economic turnaround has occurred, with a soft landing after the long period of high cost inflation in Norway and low activity in the global economy.
But inflation is too low.
The appreciation of the krone through 2002, a change in trade patterns and external economic developments have contributed to low import price inflation. Domestic competition also appears to be exerting downward pressure on inflation.
As a result of both changes in the international division of labour and increased domestic competition, there is idle labour and available real capital in Norway. Thus, it is possible that the level of output that is consistent with stable inflation will increase.
Credit developments are giving ambiguous signals to our interest-rate setting. The interest rate can be used to reduce credit demand. At present - with low interest rates abroad and a close link between domestic interest rates and the krone - a tighter monetary policy will restrain credit demand primarily because job security would be reduced.
When inflation gradually moves up from a very low level, we can begin to move towards a more normal short-term interest rate level in Norway. This may counter the emergence of excessive pressures on domestic resources in the medium term. Interest rate developments in other countries may also have a considerable impact on the krone and hence on interest rates in Norway.
When inflation is low - and as low as it is now - it is appropriate to place considerable emphasis on pushing up inflation. Therefore, we are particularly vigilant with regard to consumer price developments.
