Under the background of China s economic slow-down and property boom, financial risk analysis of listed real estate companies has gained great importance in recent years. The aim of this study is to investigate the financial risk of China s real estate companies between the years 2011 and 2015 by using Z- China score model. Based on panel data of a sample of 45 listed real estate companies, this study finds that financial risk of China s real estate industry has been increasing over the past five years, and a growing number of listed real estate companies are classified as unhealthy companies. In specific, 35 listed companies are grouped into gray area in 2015, and 4 companies are identified as financially distressed companies who are very likely to suffer financial crisis in the following two years. Further analysis identifies that profitability decline is the key factor raising the risk of a financial distress. Introduction In recent years, we have seen a slowdown in China s economic growth, with Chinese government authorities just lowering the country s GDP growth target range to 6% to 7%, which is dramatically lower than the double-digit growth in previous years. However, the real estate sector, one of the pillar industries in the national economy of China, has gained greater importance with the increase in the added value created by real estate companies which have had a large share in China s GDP growth. Contracted real estate sales have been strong throughout the past five years, to go along with inventory destocking and improved property valuations. In spite of that, the vast majority of listed real estate companies continue to suffer from profitability decline. It is widely believed that the golden age of real estate industry is over, and the silver age is coming. International credit rating agencies have lowered outlook on credit conditions in China's real estate development sector recently, and downgraded credit ratings of many listed real estate companies, even including top property developers, such as China Evergrande Group, Greenland Holding Group, Sunac China, and etc. Against this background, scholars attention is increasingly paid to financial risk of China s listed real estate companies. However, previous literature placed an emphasis on the qualitative approach, while little attention was paid to quantitative analysis. Among the few exceptions, Li and Chen [1] have evaluated the financial risk of 50 listed real estate companies based on factor analysis and clustering analysis and one real estate developer was identified as financial distressed company. Based on the Z-score model, which is one of the most frequently used risk early warning models in the literature, scholars [2,3], however, argue that a large number of real estate enterprises in China are facing tension and are very likely to suffer financial crisis. Clearly, there is a big difference between different approaches. Wang [4] warns that the accuracy rate of original Z-score model which is developed based on data in the western world is not very high to predict financial risk of China s listed real estate companies, as security markets in China are quite different from those in the western world. In general, research on financial distress and bankruptcy prediction is still at the beginning stage in China [5]. Our understanding of the financial conditions in China's real estate sector still remains an important and under-researched topic in the literature. On the other hand, 108
policymakers, analysts, and investors have an urgent need to improve their understanding of the financial risks of China s listed real estate companies. Thus, the main purpose of this study is to examine the financial risk of China s real estate companies during the period 2010-2015. To this end, this study has constructed a database of 45 listed real estate companies, which are supposed to represent the whole real estate industry in China. Following previous scholars [5], a revised Z-score model, also named Z- China score model, which is particularly developed to support identification of potential distress firms in China, is selected. The result indicates that financial risk of China s real estate industry has been increasing, and the number of financial distressed companies has increased from 0 in 2011 to 4 companies, which are very likely to suffer financial crisis in the following two years. Further analysis identifies that profitability decline is the key factor raising the risk of a financial distress. Method Z-score Model The Z-score formula for predicting financial status was published in 1968 by Professor Edward I. Altman [6]. The formula is a linear combination of several independent variables, weighted by coefficients, and a cutoff score is estimated to divide firms into healthy and unhealthy ones. It should be noted that there are a series of classic Z-score models, typically including Z-score model for public firms, Z-score model for private firms, Z-score model for non-manufacturers & emerging markets, and etc., which could be applied in different context. Based on the Z-score family of models, Altman and his colleagues [5] developed a particular model called Z- China score model, to support identification of potential distress firms in China. After considering a large number of combinations of the 15 characteristic variables, the final model to capture the distress risk of Chinese companies included just four variables, including asset liability, working capital, return on total assets, and retained earnings ratios. The formula is as follows: Z- China = 0.517-0.460X 1 + 9.320X 2 + 0.388X 3 + 1.158X 4. (1) where X 1 =asset liability ratio (total liabilities/total assets); X 2 =rate of return on total assets (net profit/average total assets); X 3 =working capital to total asset ratio (working capital/total assets); X 4 =retained earnings to total assets ratio (retained earnings/total assets). Clearly, the Z- China score model is very different from the original one, and many financial ratios usually regarded as good indicators of financial crisis by mature markets are not included in the Z- China score model, such as the stock market value to total liabilities ratio. This indicates that the current stock market value in China is not strongly correlated to company performance, which is in accordance with China's actual situation. Regarding the cutoff score, firms with Z- China score less than 0.5 (Z<0.5, dangerous area) are classified as financially distressed companies, firms with Z- China score over 0.5 and less than 0.9 (0.5 Z 0.9, grey area) are classified as potential distress ones, and firms with Z- China score over 0.9 (Z>0.9, healthy area) are classified as financially healthy ones [4]. The following test indicates that the Z- China scores model is robust with very high accuracy (a predictive accuracy of 87 percent two years prior to financial distress)[5]. Data and Sample Collection To understand the financial status dynamics of listed real estate firms, from the golden age to the silver age, financial data from year 2010 to 2015 will be analyzed via panel data analysis. In consideration of representativeness and data availability, this study has conducted an extensive review to real estate companies in China, and used the following criteria for filtering the large number of real estate companies: 1) core business are real estate development, 2) listed in contract sales Top 100 in the first half year 2016, and 3) based in China. As a result, a sample of 45 listed 109
real estate companies (including Shanghai, Shenzhen and Hong Kong stock exchanges) are selected. Then, all financial data needed for this study has been extracted from the annual reports of every company, during the period 2011-2015. Analysis and Result Z-score Analysis Based on the Z- China score formula, this study processes the data with Excel software and obtains Z scores of every listed company during period 2010-2015 (see Table 1).

Regarding the sample average, it has decreased gradually from 0.9210 in 2011 to 0.7225 in 2015, reflecting the financial risk in China s real estate sector has been increasing year by year, from healthy area to gray area. It is worth noting that Z scores of the ones whose credit rating have been downgraded by international credit rating agencies have indeed decreased in varying degrees. Table 2 presents the classification of listed real estate companies based on Z scores. As shown, in 2011, 22 and 23 out of the sample companies were grouped into healthy and gray areas respectively, and no one was classified as financially distressed company. Unexpectedly, the result is in contrast with previous scholars [2,3] who have demonstrated that a large number of real estate enterprises in China were very likely to suffer financial crisis in this period. As such, this finding provides additionally support to Wang s [4] conclusion that the accuracy rate of the original Z-score model for predicting financial risk of China s listed companies is not very high. However, 35 listed companies were grouped into gray area in 2015 and only 6 companies were classified as financial healthy ones. Meanwhile, it should be stressed that 4 companies even were identified as financially distressed ones, which are very likely to suffer financial crisis in the following two years. Table 2. Classification table for the three groups of listed real estate companies.

To identify the specific factors leading to financial risk increase, further analysis is conducted to the four variables in the Z- China score formula and the relevant financial indicators. As shown in Table 3, the increasing financial risk of China real estate sector is mainly caused by the falling ROA (Return On Assets), namely the variable X2. It is worth noting that the average ROA of the sample companies has declined from 5.06% in 2011 to 2.86% in 2015. In other words, profitability decline is the most important factor raising the risk of a financial distress in the past five years. Generally, asset-liability ratio is the second most important factor. 111

The empirical analysis indicates that financial risk in China real estate sector has been increasing over the past five years, and a growing number of companies are classified as unhealthy ones. Particularly in 2015, the vast majorities (78%) of listed companies were grouped into the gray area, indicating the potential distress of these companies, and only 6 companies were classified as financial healthy ones. Moreover, 4 companies even were identified as financially distressed companies. The results are in line with the viewpoints of international credit rating agencies who have lowered outlook on credit conditions in China's real estate development sector. Further analysis shows that profitability decline is the key factor raising the risk of a financial distress. As such, this study provides empirical support to the argument that the Z- China score model is, to some extent, a suitable model to identify the financial risk of Chinese companies. Moreover, Chinese real estate companies are suggested to reduce operational cost and lower asset-liability ratio, to reduce the financial risk and eventually survive in the new normal economy, where real estate companies will face much more challenges. Furthermore, this study provides important implications for policy makers, and close watch is expected to the increasing financial leverage ratio of real estate companies who have had a large share in China s GDP growth in recent years.
