REFERENCES Nguyen Thanh Quang CQ53/51.02 Graduation thesis Academy of Finance INTRODUCTION Rationale of the study International economic integration is an inevitable trend of mankind, taking place strongly not only in the region but also around the world With this trend in mind, Vietnam has also made strong steps to bring a lot of development opportunities for its economic sectors Through many difficulties and challenges, our economy has achieved encouraging achievements To achieve that, there is a significant contribution of the banking industry as an "economic lever" through credit activities Bank credit is a tool to finance capital for the economy, contributing to the promotion of the balanced development of other industries and sectors according to the State's orientation Credit activity is the main business of the Vietnamese commercial banking system, bringing about 80-90% of each bank's income, but its risks are not small Excessive high credit risk will greatly affect the banking business Facing the opportunities and challenges of the process of international economic integration, the issue of improving the competitiveness of commercial banks, particularly improving credit quality and minimizing risks, has become necessary Actually, there are many internal and external reasons causing credit risks situation for the Bank in Viet Nam The lack of management skill, for example, can limit the profitability and competiveness of the Bank As a result, many theories as well as some solutions related to credit activity issues are carried out Starting from the urgency of the problem, I decide to carry out research Nguyen Thanh Quang CQ53/51.02 Graduation thesis Academy of Finance an information security strategy and detailed action plan through 2020 with E&Y’s advice The strategy includes over 40 information security projects to develop comprehensive capabilities that encompass processes, technologies, and people In 2017, VPBank carried out over 10 projects to strengthen its information security system and facilitate the digital strategy Those projects are part of the Bank’s long-term strategy and instrumental in improving the information security system in line with the roadmap Debt collection The year 2017 laid a solid foundation for rapid, sustainable improvements in collection by putting in place a young, dynamic, well-trained team, investing in and developing systems and tools to boost collection efficiency The Bank deployed Medialtel & Tethys, an automated dialing and collection software system, which helped make three million calls and send one million SMS messages and 16,000 email messages as reminders In addition, VPBank actively supported customers who faced temporary financial difficulties by working out appropriate financial solutions for them so that they can continue their business, thereby reducing NPLs The Bank also made use of the National Assembly’s Resolution no 42/2017/QH14 on resolving NPLs at credit institutions to seize collateral, shorten legal proceedings, etc to effectively resolve NPLs The strategic goal for 2018 is to further develop and strengthen foundational systems, particular risk management and information security The Bank will focus on improving risk management productivity and efficiency through process improvement, in particular the re-assessment of customer rating criteria, to optimize the automatic approval system, increase collaboration efficiency and quality of support to business functions in product development, periodic risk assessment and resource optimization In terms of collection, beside conventional methods, VPBank will also adopt new debt reminder methods such as Zalo and video messages to curb the increase in NPL buckets and reduce the Nguyen Thanh Quang 45 CQ53/51.02 Graduation thesis Academy of Finance NPL ratio The Bank will continue to reinforce operational risk management and fraud prevention by focusing on high risk areas, applying data mining techniques and raising staff’s risk awareness 2.3: General assessment of credit activity at Viet Nam Prosperity Joint Stock Commercial Bank Customer need loan Nguyen Thanh

projects, over 1,500 changes and 2.5 time growth pace against 2016 Initiatives on changing the core systems, network control allows the Bank to save considerable costs on license and telecommunication In 2017, the Bank approved the Information Technology Strategy for the 2017 – 2020 period, which paves the way for the Bank’s digitization journey The technical aspects and organizational structure of over 250 initiatives were technically approved and this will help the Bank: • Open up opportunities for cooperation with business partners • Get ready to expand business and outsource a number of

SOLUTIONS TO IMPROVE CREDIT PERFORMANCE AT VIETNAM PROSPERITY JOINT STOCK COMMERCIAL BANK 3.1: The development of orientation of the Bank Oriented development Socio-economic development orientation in 2015 The Party and sectoral departments always follow closely the direction of socio-economic development in the locality, implement policies consistently.by developing a diversified commodity economy of components, operating under the market mechanism and under the supervision and management of the State Besides, VP bank always create favorable conditions for investment and development of local businesses, contributing to promoting the socio-economic development Current market demand: Hanoi is one of the places with high socio-economic development index in the country, corresponding to that development, the demand for credit of the population is also increasing This is shown in detail as follows: The number of enterprises by the end of 2016 is 20,183 enterprises, an increase of 42% compared to 2015 The number of fast-growing enterprises requires a large amount of capital to meet development needs VP Bank's development orientation: Ensuring the growth target "Safety Efficiency - Sustainability" The growth target is always placed at the top That is not only a target in a certain period but it is a norm throughout the long-term operation of VP Bank Based on development-oriented construction bases, VP Bank tries to fulfill specific targets as follows: Enhancing capital mobilization with the target of over VND 300 billion Further boost lending to non-state sector with the target of more than VND 100 billion Nguyen Thanh Quang 50 CQ53/51.02 Graduation thesis Academy of Finance The work of preventing overdue debt is focused, minimizing operational risks by enhancing debt recovery and risk management, reducing overdue debt ratio to below 2% Adjusting the debt balance on mobilized capital to less than 200% to minimize risks in business operations of the Branch Completing credit appraisal, especially business credit assessment: classifying specific portfolio of enterprises by industry, by scale to be able to provide credit process specific for each business 3.2: Some solutions to improve credit performance at Viet Nam Prosperity Joint Stock Commercial bank 3.2.1: Promoting capital mobilization The basis of the solution Commercial banks operate on the principle of "borrowing to lend", so mobilized capital plays a very important role in the bank's operations The bank wants to operate effectively, it needs a stable source of capital mobilization to be a prerequisite for development Besides, according to analysis results, the mobilized capital of the Branch in terms of value has increased over the years but the growth rate of capital mobilization in 2017 compared to 2016 is only 18.43%, while This growth rate in 2016 compared to 2015 reached 27.62% Therefore, the branch needs to devise appropriate measures to attract capital for the bank, avoid capital shortage and not provide enough for the economy The purpose of the solution This solution provides appropriate capital mobilization strategies to attract idle capital in the population, increase mobilized capital, contribute to adjust the debt balance ratio on mobilized capital at a more reasonable level Nguyen Thanh Quang 51 CQ53/51.02 Graduation thesis Academy of Finance Implementation of the solution Diversifying savings deposit products, capital mobilization forms With savings deposit products, Vp bank creates flexible options for customers such as sending once but flexible original withdrawal still get high interest, sending donations but pay out once in the end of the term with attractive interest rates; 6-month, 9-month, 12-month multi-purpose savings account allows flexible root withdrawal, savings deposit associated with life insurance; sending money together with loan for buying installment cars Diversifying capital mobilization form Issuance of international bonds to borrow foreign capital to finance enterprises and customers with investment projects with high feasibility Provideing a flexible interest rate policy which adjusts the interest rate appropriately to each specific socio-economic stage At the same time, give the policy of preferential interest rates for large customers 3.2.2: Marketing and customer service promotion The basis of the solution The nature of marketing is the process of determining the specific needs of the market The branch needs to understand what customers really need, at the same time evaluate the competencies of competitors and their ability to offer optimal solutions to meet customers' needs in a good way Best Therefore, Marketing increasingly plays an important role and becomes an indispensable tool in the business strategy of most banks But now, the Branch still has a situation of waiting for customers to send and borrow money, this is a dynamic plan that needs to be adjusted immediately Nguyen Thanh Quang 52 CQ53/51.02 Graduation thesis Academy of Finance The purpose of the solution Aiming to help the Branch to capture strong points and internal weaknesses of the Branch to be able to adjust more appropriately to the market demand Besides, it helps the Branch to promote the image promotion, creating trust with existing customers and attracting more new customers At the same time, the Branch can further improve the customer information system Implementation of the solution The first is making the research and collecting customer information monthly Bank analyze processed information to make estimates, conclusions about the needs of current and potential customers about the situation of competition between VP bank and other banks and between banks and the ability of VP Bank to meet market demand The second is updating market trends Because the current workload has been increasing , the number of personnel of Customer Relation Department and Risk Management is limited, requiring employees to be more than computer proficient and computer processor must continuously be supplemented and fostered knowledge of market economy, market changes, corporate finance, science and technology, modern banking operations and at the same time consolidate and improve the ability to synthesize and analyze data 3.2.3: Diversifying credit products The basis of the solution Diversifying products is always an effective strategy for a bank with a position like VP bank Diversifying credit products creates more credit products, more suitable for customers, making customers more secure for credit products However, the package of products for VP Bank's credit customers has not been diversified, only encapsulated in traditional products such as lending each time, Nguyen Thanh Quang 53 CQ53/51.02 Graduation thesis Academy of Finance not yet launched new products, forms of credit, regulation Lending process lacks flexibility Therefore, in order to improve its competitiveness and position, the Branch must always pay attention to the development of lending products to make a difference for itself in the market The purpose of the solution VP Bank expands loan objects and lending products to develop market share for banks Besides, there are various types of loan lists and payment methods to create satisfaction and comfort for customers Implementation of the solution Offering flexible lending interest rates In order to attract customers, the Branch needs to build a list of attractive and flexible interest rates, depending on each period or each object, but the interest rate policy will be different 3.2.4: Improving professional qualifications of credit officers People are the subjects of lending in credit relations, who are directly involved in all tasks from planning policies, to project appraisal, loan approval, loan use and collection check in debt It can be said that all right and wrong, success or failure of credit projects in addition to objective causes contains subjective elements of credit officers Due to the specificity of this work, it is a wide exchange with many enterprises and many economic sectors At the same time, it is always necessary to grasp the market economy situation, production and business situation of credit-related units Use with banks, so choosing a credit officer to deliver is very important Therefore, credit officers must meet the following criteria: be honest, have the necessary level of economic knowledge, finance and have a seniority in banking operations or in other words, must have sufficient reliability VP bank should regularly organize training, professional training to contribute to improving professional qualifications, especially focusing on the ability to assess, analyze business results and the use of loans The bank regularly sends its staff to Nguyen Thanh Quang 54 CQ53/51.02 Graduation thesis Academy of Finance visit and learn from experiences of other domestic and foreign banks in creditrelated fields In addition to professional knowledge, credit officers must be knowledgeable about laws and foreign languages to serve their work, banks need to create conditions for staff to learn more to improve their knowledge Informally, study the Government Decrees, Decisions and documents of the State Bank 3.2.5: Loan monitoring promotion Loan monitoring is one of the most important steps in the credit process at banks It should be done to ensure the loan security is used for the right purpose of borrowing, ensuring debt recovery ability Current loan monitoring in the Branch only focuses on the review of the latest financial statements, some related invoices Credit officers come to the facility to check (at least once every two months), however such monitoring will not detect timely events occurring in the enterprise, especially the integrity of the financial statements that business offers Monitoring the use of loans by customers is considered an effective measure to prevent risk The monitoring will help the bank to control the behavior of borrowers, capture information, monitor and update the situation of loans and the situation of customers in a timely manner, but above all it makes sense limiting arising credit risks, ensuring the efficient use of capital and the right purpose The bank should organize a careful and serious control process to ensure that it evaluates and considers all the most important characteristics of the loan, such as assessing the payment process, evaluating performance and love mortgage status, fully considering the legal aspect of the credit contract to ensure that the bank has the legal right to own all or part of the collateral of the enterprise in case the customer does not repay the debt, assess the change in the borrower's Nguyen Thanh Quang 55 CQ53/51.02 Graduation thesis Academy of Finance financial situation and the change in forecasts, assess the factors that reduce borrowers' credit needs 3.2.6: Participating in credit insurance Each loan has a certain risk ratio, so the risk is always likely to occur in any case Branches should take measures to prevent risks as well as minimize losses caused by risks This insurance method is relatively suitable in the current conditions of Vietnam Therefore, this company operates under the intervention of commercial banks such as forcing commercial banks to participate in insurance and assistance when necessary This insurance method promotes community and mutual support of commercial banks, credit institutions contribute to ensuring the safety in business of each commercial bank as well as safety in the banking system When businesses are at risk of leading to the inability to pay with the Bank Depending on the nature of each type of risk and the financial situation of an enterprise, commercial banks may use the following measures: extracting customers' deposit accounts at commercial banks, extending credits and selling such assets mortgage, debt freezing and finally offset by risk fund In addition to the establishment of a Risk Compensation Fund, in order to overcome the limitation of this fund, commercial banks may participate in insurance with great credit and credit insurance benefits as follows Firstly, credit insurance is obliged to compensate commercial banks when risks occur In addition, credit insurance is also obliged to coordinate with related agencies to organize measures to prevent and limit losses occurring to ensure safety for insurance companies as well as safety for Commercial banks Secondly, credit insurance attracts many customers to participate in insurance, so it has the ability to pay quickly and promptly to compensate for big losses and promote community, mutual assistance among banks Nguyen Thanh Quang 56 CQ53/51.02 Graduation thesis Academy of Finance 3.3: Recommendations for Vietnam Prosperity Joint Stock Commercial Bank Firstly, It is necessary to carry out and instruct specifically the SBV's decision documents on Banking activities for affiliated Bank branches, ensuring accuracy, timeliness, and synchronization throughout the system Secondly, VP bank needs to research and promulgate financial regulations, organize and reward its own disciplines for officials involved in the credit process to create a better motivation to work Lastly, Bank need to strengthen and further strengthen inspection and control, in order to promptly detect and promptly handle violations, minimize possible losses and improve credit efficiency through the system CONCLUSION Credit activity is an important factor, it determines the existence and development of VP Bank in the current market economy In order for the Branch's business activities to develop more and more diverse, especially in the field of credit, it requires the Branch to constantly improve and improve banking technology to meet the banking modernization process, improve competitiveness Besides, it is necessary to have a team of staff to meet the job in the new period, good at professional skills and must be professionally qualified, good at professional skills to meet the level of innovation and development of banking technology, while avoiding occupational risks Although there are many difficulties in capital mobilization, it is impossible to meet 100% of customers' borrowing needs However, the Branch will try to continue to make it possible to get closer to customers, provide more banking services to meet customers' needs in the maximum possible way, while improving competitiveness in current conditions In the future, with the great potential of Vietnam's credit market, plus the right business strategy and the efforts of the Branch In addition, it is the active Nguyen Thanh Quang 57 CQ53/51.02 Graduation thesis Academy of Finance support of Vietnam Joint Stock Commercial Bank of Vietnam, VP bank will reach higher results, bring card service to become one of its leading services, and strengthen and further develop its position in the credit market The research reflected the current situation of VP Bank in Kim Lien branch However, due to the fact that the knowledge is not sufficient in all aspects as well as time constraints, the article cannot avoid shortcomings We are looking forward to receiving the comments of teachers, working officers at VP Bank so that the internship report is more practical By determining the actual financial situation, analyzing and evaluating the credit operation management at Viet Nam Prosperity Joint Stock Commercial Bank, I have gained new insight into the results of the company gained during long periods of operation and the limitations that the company still needs to resolve By finding solutions to overcome these problems, enterprises can improve their ability to manage credit operation efficiently and benefit the businesses themselves, achieve goals outlined Nguyen Thanh Quang 58 CQ53/51.02 Graduation
