(In research, why is it important to define research problem appropriately? Mention. Also, explain the techniques involved in defining the research problem.)

Answer

Importance of defining the research problem appropriately

  1. Gives direction and focus — A clearly defined problem tells the researcher exactly what to study, so effort is not wasted on irrelevant areas.
  2. Determines objectives and hypotheses — Objectives, research questions and hypotheses can only be framed once the problem is precisely stated.
  3. Guides research design — The choice of design, sampling method, tools of data collection and techniques of analysis all follow from the nature of the problem.
  4. Prevents duplication and wastage — It helps avoid repeating work already done and saves time, money and manpower.
  5. Keeps the study within feasible limits — A well-defined problem is narrow enough to be completed within the available time, budget and competence.
  6. Facilitates clear communication — A precise statement of the problem makes the purpose understandable to guides, respondents, funding agencies and readers.
  7. Improves validity of findings — A wrongly defined problem leads to wrong data and misleading conclusions; correct definition increases the reliability and usefulness of results.

Techniques involved in defining the research problem

  1. Statement of the problem in general terms — The researcher first states the problem broadly, e.g. "the fall in saving habit of urban households".
  2. Literature review — Reading books, journals, reports and previous theses to understand what is already known and where the gap lies.
  3. Discussion with experts, guide and colleagues — Seeking their experience and suggestions to sharpen the focus of the problem.
  4. Analysis of the problem (rephrasing) — Breaking the broad problem into specific components and rephrasing it into a workable research question or hypothesis.
  5. Defining concepts and variables — Clearly defining the key terms and variables so that they are measurable and understood in the same sense by all.
  6. Setting objectives and scope — Fixing the objectives, area, population, time period and unit of analysis of the study.
  7. Pilot study / pre-test — Conducting a small preliminary study to test whether the problem is properly defined and the tools are suitable.
  8. Feasibility check — Examining whether the problem can be studied within the available resources, and refining or narrowing it if necessary.

(What is sample design? What are the components of a sample design? Explain Snowball Sampling Method with its advantages and limitations.)

Answer

Sample Design

Sample design is the definite plan or scheme that the researcher prepares in advance for selecting a sample from the population. It specifies how the units of the population are to be chosen, how many are to be chosen, and the procedure by which the sample data will be collected and analysed. In short, it is the blueprint of the whole sampling operation — it decides the technique of sampling, the size of the sample, and the method of drawing the sample. A good sample design must be reliable, unbiased, and representative of the population, and it must fit within the time, cost and resources available to the researcher.

Components of a Sample Design

  1. Population (universe) definition — clear identification of the total set of units from which the sample is drawn (e.g., all households of Kathmandu district).
  2. Sampling unit — the individual element or group of elements that is selected in the sample (a household, a firm, a student).
  3. Sampling frame — the list, map or source from which the sample units are actually picked (voter list, census list, telephone directory).
  4. Sampling technique/method — the method used to select units, i.e. probability (random, systematic, stratified, cluster) or non-probability (convenience, judgment, quota, snowball).
  5. Sample size — the number of units to be included in the study, decided on the basis of precision required, variability in the population, confidence level and available budget.
  6. Sampling plan and procedure — the operational steps for contacting units, collecting data, and handling non-response.
  7. Budget and time schedule — the cost and time limits within which the design must be executed.
  8. Precision/error tolerance — the acceptable level of sampling error and the confidence level desired.

Snowball Sampling Method

Snowball sampling (also called chain-referral sampling) is a non-probability sampling technique in which the researcher first identifies a few respondents who meet the criteria of the study, and these initial respondents then refer other persons known to them who also qualify. Those referred persons, in turn, refer further persons. Thus the sample grows like a rolling snowball — small at the start and larger as it rolls on. It is used mainly when the population is hidden, rare or hard to reach, e.g. drug users, sex workers, street children, illegal migrants, or persons with a rare disease, for whom no sampling frame exists.

Advantages

  1. Useful for studying hidden, rare or sensitive populations where no list/frame exists.
  2. Low cost and less time-consuming compared to locating such respondents individually.
  3. The researcher gains access through trust and personal referral, so respondents are more willing to cooperate and disclose sensitive information.
  4. Useful in exploratory and qualitative research to reach a wide network quickly.
  5. Requires no sampling frame, which is often impossible to prepare for such groups.

Limitations

  1. It is a non-probability method, so the sample is not representative and results cannot be generalized to the whole population.
  2. Selection bias is high — the researcher's initial contacts and the network itself decide who enters the sample.
  3. The sample may be confined to one social network or locality, leaving other segments unreached.
  4. The size and composition of the sample cannot be controlled or predicted in advance.
  5. Respondents may refuse to refer others (privacy concerns), and referral chains may die out early.
  6. Statistical inference (margin of error, confidence interval) cannot be validly applied.

(If you are assigned to prepare a questionnaire for the research study on "Loan status of loans of microfinance institutions", how would you prepare the questionnaire for loanee? Describe with examples.)

Answer

Preparing a Questionnaire on the Loan Status of Microfinance Loanees

A questionnaire is a structured set of questions designed to collect primary data from respondents. For a study on the loan status of loanees of microfinance institutions (MFIs), the questionnaire must be prepared systematically so that reliable and comparable data are obtained. The following steps show how I would prepare it for loanees.

1. Determine the Objectives of the Study

The questionnaire must be built around clear objectives, such as:

  • To find out the purpose for which loans are taken.
  • To assess the amount of loan, repayment status, and outstanding balance.
  • To identify the problems faced in repayment.
  • To measure the impact of loans on the loanees' income and living standard.

2. Identify the Respondents and Data Needs

Respondents are existing loanees of MFIs. The data needed are facts (loan amount, repayment, overdue), opinions (satisfaction, difficulty), and personal details (age, occupation, income).

3. Decide the Type and Sequence of Questions

  • Begin with easy, factual questions and move to sensitive ones.
  • Use closed-ended questions (dichotomous, multiple choice, rating scale) for easy coding, and a few open-ended questions for depth.
  • Avoid leading, double-barrelled and ambiguous questions.

4. Design the Structure

A good questionnaire has three parts:

  1. Covering letter – purpose, assurance of confidentiality, and thanks.
  • Personal information – background of the loanee.
  • Core questions – loan details, utilization, repayment, problems and suggestions.

5. Pre-test and Finalize

The draft is pre-tested on a few loanees to remove unclear or irrelevant questions, then finalized.


Model Questionnaire (with Examples)

A. Personal Information

  1. Name (optional): ……………
  2. Age: (a) Below 25 (b) 25–35 (c) 36–45 (d) Above 45
  3. Occupation: (a) Farming (b) Trade (c) Service (d) Others ………
  4. Monthly family income: (a) Below Rs 10,000 (b) Rs 10,000–20,000 (c) Above Rs 20,000

B. Loan Details 5. From which MFI have you taken the loan? …………… 6. How many times have you taken a loan? (a) Once (b) Twice (c) Three times or more 7. What was the amount of your latest loan? (a) Below Rs 50,000 (b) Rs 50,000–1,00,000 (c) Above Rs 1,00,000 8. For what purpose was the loan used? (a) Agriculture (b) Small business (c) Education (d) Household consumption (e) Others ………

C. Repayment Status 9. What is your present repayment status? (a) Fully repaid (b) Repaying regularly (c) Irregular (d) Overdue 10. How much loan is still outstanding? Rs …………… 11. How much installment do you pay per month? Rs …………… 12. Have you ever missed an installment in the last 12 months? (a) Yes (b) No 13. If yes, what was the main reason? (Open-ended) ……………………………………………………

D. Problems and Impact 14. Rate the following problems on a 5-point scale (1 = strongly disagree, 5 = strongly agree):

Statement12345
Interest rate is too high
Repayment period is too short
Group pressure is burdensome
  1. Has the loan helped to increase your income? (a) Yes (b) No (c) No change
  2. What suggestions do you have to improve MFI loan services? (Open-ended) ……………………………………………………

Conclusion

Thus, the questionnaire is prepared by setting objectives, identifying respondents, choosing appropriate question types and sequence, structuring it into covering letter, personal information and core loan-related questions, and pre-testing it. This ensures valid, reliable and complete data on the loan status of microfinance loanees.

(What is meant by the relationship between reliability and validity of data? Explain the way to assess the validity of a multi-item scale.)

Answer

Meaning of the relationship between reliability and validity of data

Reliability refers to the consistency, stability and dependability of a measurement instrument — the same instrument, applied repeatedly to the same object under the same conditions, yields consistent results. Validity refers to the correctness or truthfulness of a measurement — the instrument measures what it is actually intended to measure. The relationship between them is one of necessary but not sufficient condition:

  • Reliability is a necessary condition for validity: if a scale gives inconsistent results from one administration to the next, it cannot be measuring the true construct, so an unreliable scale cannot be valid.
  • Reliability is not a sufficient condition for validity: a scale may be perfectly consistent yet consistently wrong (e.g., a weighing scale that always reads 2 kg too high). Such a scale is reliable but not valid.
  • Validity implies reliability: if a scale truly measures the intended construct, its measurements will also be stable and consistent. Thus validity is the stronger and more fundamental requirement.
  • Symbolically: a measure can be reliable but not valid; it cannot be valid but unreliable. Reliability sets the upper limit of validity (validity ≤ √reliability).

Ways to assess the validity of a multi-item scale

A multi-item scale (e.g., a 5-point Likert scale with several items measuring one construct) is assessed for validity through the following approaches:

  1. Content (face) validity — judgmental assessment by experts and respondents of whether the items adequately cover the entire domain of the construct. Items are checked against the theoretical definition and the literature; items with poor relevance are deleted. This is assessed before data collection.
  2. Item–total correlation — the correlation of each item score with the total scale score. Items with low correlation (say below 0.30) are considered not contributing to the construct and are dropped. This is a preliminary purification step.
  3. Construct validity — the extent to which the scale actually measures the theoretical construct. It has two parts:
    • Convergent validity: the scale should correlate highly with other measures of the same construct. Assessed by correlation between the scale and a theoretically related measure, or by factor loadings in exploratory factor analysis (loading ≥ 0.50 on the intended factor).
    • Discriminant (divergent) validity: the scale should correlate weakly with measures of different constructs. Assessed by comparing the average variance extracted (AVE) of each construct with the squared correlation between constructs — AVE should exceed the squared inter-construct correlation.
  4. Criterion-related validity — the extent to which scale scores predict an external criterion:
    • Concurrent validity: correlation of the scale with a criterion measured at the same time (e.g., a new job-satisfaction scale against an established one).
    • Predictive validity: correlation of the scale with a criterion measured at a later time (e.g., an aptitude test score against later job performance).
  5. Factor analysis — exploratory factor analysis (EFA) checks whether the items load on the expected number of factors and whether the factor structure explains sufficient variance; confirmatory factor analysis (CFA) tests model fit (χ²/df, CFI, RMSEA) and reports AVE and composite reliability for each construct.
  6. Content adequacy through expert rating (content validity index) — experts rate each item as essential or not; the content validity ratio/index is computed to retain only items agreed upon by experts.
  7. Nomological validity — checking whether the scale behaves as predicted within a wider theoretical network of related constructs.

In practice, a multi-item scale is first purified through item–total correlation and EFA, then its construct validity is confirmed through convergent and discriminant evidence (AVE, factor loadings, inter-construct correlations), and finally its criterion-related validity is established by correlating scale scores with an appropriate external standard.

(What are the components of research proposal? Briefly describe. If you are preparing the research proposal, how do you define the research methods used in the research? Write.)

Answer

Components of a Research Proposal

A research proposal is a written plan that outlines what the researcher intends to study, why it is worth studying, and how it will be carried out. Its major components are:

  1. Title of the Study — A clear, specific and concise statement reflecting the subject, variables and scope of the study.
  2. Introduction / Background — Background information on the topic, the existing situation, and the context in which the problem lies.
  3. Statement of the Problem — A clear description of the gap between the existing situation and the desired situation, expressed in question form.
  4. Objectives of the Study — Specific, measurable statements of what the research aims to achieve.
  5. Research Questions / Hypotheses — Questions to be answered, or tentative propositions to be tested.
  6. Rationale / Significance of the Study — Why the study matters to theory, policy, practice or society.
  7. Literature Review — Summary and critical evaluation of previous studies, showing the research gap.
  8. Conceptual / Theoretical Framework — The concepts, variables and their expected relationships that guide the study.
  9. Research Methodology — Research design, population, sample and sampling technique, data collection tools, data analysis methods, and ethical considerations.
  10. Scope and Limitations — The area, time and units covered, and the constraints the study faces.
  11. Chapter Plan / Organization of the Study — The proposed structure of the final report.
  12. Work Schedule (Time Schedule) — A Gantt-type plan showing activities and time required.
  13. Budget / Cost Estimate — Estimated expenditure on personnel, travel, stationery, data processing, etc.
  14. References / Bibliography — List of sources cited, in a standard format (APA, etc.).
  15. Appendices — Questionnaire, interview schedule, and other supporting documents.

How I Would Define the Research Methods Used

While preparing the proposal, I would define the research methods under the "Research Methodology" section in the following manner:

  1. Research Design — State whether the study is descriptive, exploratory, causal or case-study based. For most management studies, a descriptive and analytical design is suitable.
  2. Nature of Data — Specify whether primary data, secondary data or both will be used, and justify the choice.
  3. Population and Sample — Define the population clearly (e.g., all employees of commercial banks in Kathmandu Valley), determine sample size using a formula such as Cochran's or Yamane's, and state the sampling technique (random, stratified, purposive, etc.).
  4. Data Collection Tools and Techniques — Mention the instruments: structured questionnaire, interview schedule, observation checklist, focus group discussion, or document review. State the number of items, the scale used (Likert 5-point, etc.) and the pre-testing of the instrument.
  5. Validity and Reliability — Explain how content validity will be ensured (expert review) and how reliability will be tested (Cronbach's alpha, pilot test).
  6. Data Analysis Techniques — Mention descriptive tools (frequency, percentage, mean, standard deviation) and inferential tools (correlation, regression, chi-square, t-test, ANOVA) as required by the objectives and hypotheses. State the software to be used (SPSS, Excel).
  7. Ethical Considerations — Assure informed consent, anonymity, confidentiality, voluntary participation and avoidance of plagiarism.
  8. Limitations of the Method — Mention constraints such as time, cost, sample size and geographical coverage.

In this way, the research methods are defined in terms of design, data, sample, tools, analysis and ethics, so that the study becomes systematic, verifiable and replicable.

(What is a Computer System? Explain the functions of Computer Operating System.)

Answer

Computer System

A computer system is an organised combination of hardware, software, data, people and procedures that works together to accept input, process it according to stored instructions, store the results and produce meaningful output. It is not merely a machine; it is a complete working unit in which the physical parts and the programs cooperate to convert raw data into useful information.

Components of a computer system

  1. Hardware – the tangible, physical parts such as the CPU (ALU + control unit), memory (primary and secondary), input devices (keyboard, mouse, scanner) and output devices (monitor, printer). The CPU is the "brain" that executes instructions.
  2. Software – the set of programs that direct the hardware. It is of two types:
    • System software – operating system, device drivers, utilities, language translators.
    • Application software – general-purpose (MS Word, Excel) and specific-purpose (payroll, billing) packages.
  3. Data/Information – raw facts fed as input, which are processed into meaningful information. Data are stored in files and databases.
  4. People (Users) – the human beings who operate the system, such as end users, programmers, analysts and operators.
  5. Procedures – the documented rules and steps (e.g. backup policy, password policy) that govern the use of the system.

These five elements together form the information processing cycle: input → process → store → output → control.

Functions of a Computer Operating System

An operating system (OS) is the master system software that acts as an interface between the user and the hardware and manages all the resources of the computer. Without an OS, a computer is only a collection of electronic components. Its major functions are:

1. Process Management – The OS creates, schedules, suspends and terminates processes. It allocates CPU time among competing programs using scheduling techniques (FCFS, round robin, priority), handles interrupts, and provides facilities for inter-process communication and synchronisation so that many programs can run together without conflict.

2. Memory Management – It keeps track of every byte of main memory — which part is occupied, by whom, and which part is free. It allocates memory to programs on demand, uses techniques such as paging, segmentation and virtual memory, and reclaims memory when a process ends. It also protects one program's memory space from another's.

3. File Management – The OS creates, opens, reads, writes, renames, copies and deletes files and directories. It maintains the directory structure, keeps track of free disk space, controls access permissions (read/write/execute) and organises data into a logical hierarchy so that users can retrieve it easily.

4. Device (I/O) Management – Through device drivers, the OS controls input/output devices, allocates them to processes, buffers and spools data (e.g. print spooling), and resolves conflicts when several programs demand the same device. It hides hardware details from the user.

5. Job Scheduling and Resource Allocation – It decides the order in which jobs are admitted and executed, allocates CPU time, memory and devices among users, and maximises utilisation of the system in multiprogramming and time-sharing environments.

6. User Interface – It provides the environment through which the user communicates with the machine — the command-line interface (CLI) or the graphical user interface (GUI) with icons, windows and menus.

7. Security and Protection – It authenticates users by password or biometrics, assigns access rights, prevents unauthorised access to files and memory, and maintains logs/audit trails of system activity.

8. Error Detection and Handling – It detects hardware faults (power failure, memory error, device failure) and program errors (division by zero, illegal instruction), reports them to the user and takes corrective action so that the system does not crash.

9. Networking and Communication – Modern operating systems manage network connections, allow file and printer sharing, and support communication between computers through protocols such as TCP/IP.

10. File System and Utility Services / Accounting – They keep records of resource usage by each user for billing and performance monitoring, and provide utility programs for backup, disk defragmentation, formatting and virus protection.

Conclusion – A computer system is thus a complete man–machine unit, and the operating system is its resource manager and coordinator. By managing processes, memory, files, devices and security, the OS makes the hardware usable, efficient and safe for the user.

(Explain the major features and uses of LAN, WAN and MAN. Also, differentiate between Internet and Intranet.)

Answer

Major Features and Uses of LAN, WAN and MAN

1. Local Area Network (LAN)

Features:

  • Covers a small geographical area such as a single office, school, building or campus (usually within a few hundred metres).
  • High data transmission speed (typically 100 Mbps to 1 Gbps or more).
  • Low setup and maintenance cost; owned and managed privately by a single organisation.
  • Low error rate and simple topology (bus, star, ring).
  • Uses guided media such as UTP/STP cable, coaxial cable or fibre optics; Wi-Fi is also common.

Uses:

  • Sharing files, printers, scanners and other hardware among computers in an office.
  • Centralised storage and application servers within an organisation.
  • Internal email, database access and workgroup collaboration.
  • Computer labs in schools and colleges, banking branches and hospital departments.

2. Metropolitan Area Network (MAN)

Features:

  • Covers a city or a metropolitan area, typically 5 km to 50 km.
  • Larger than a LAN but smaller than a WAN.
  • Moderate to high speed (usually 10 Mbps to 100 Mbps).
  • Owned by a single organisation or by a telecom/service provider; may be public or private.
  • Interconnects several LANs within the same city.

Uses:

  • Connecting branches of a bank, college or government office within a city.
  • Cable TV networks and city-wide internet services.
  • Linking different campuses of a university in the same city.
  • Metropolitan area networks for municipal e-governance services.

3. Wide Area Network (WAN)

Features:

  • Covers a very large geographical area — a country, a continent or the whole world.
  • Lowest transmission speed among the three (often a few Mbps to tens of Mbps).
  • Very high setup and maintenance cost; usually owned by telecom carriers or leased from them.
  • Uses public transmission media such as telephone lines, microwave, satellite and undersea fibre cables.
  • Higher error rate and greater security risk due to long distance and public links.

Uses:

  • Connecting offices and branches of multinational companies across countries.
  • The Internet itself is the largest example of a WAN.
  • Remote banking, airline reservation systems and national ID/passport systems.
  • Cloud services, remote login and nationwide data communication.

Difference between Internet and Intranet

BasisInternetIntranet
MeaningA global network of interconnected networks open to everyone.A private network within an organisation using Internet technology.
CoverageWorldwide.Limited to one organisation or its branches.
OwnershipNo single owner; publicly shared.Owned and controlled by the organisation.
AccessibilityOpen to any user with a connection.Only authorised employees/members with login.
SecurityLess secure; needs firewalls and antivirus.More secure; protected by firewalls and access control.
UsersUnlimited public users.Limited internal users.
PurposeInformation sharing, communication, e-commerce, entertainment.Internal file sharing, notices, HR records, collaboration.
Examplewww.google.com, www.nepal.gov.npCollege intranet portal, bank's internal staff portal

Conclusion: LAN, MAN and WAN differ mainly in geographical coverage, speed and ownership. The Internet is a public global WAN, whereas an intranet is a private network built on the same technology but restricted to an organisation's internal users.

(Define Database. Discuss the functions of database management system in brief.)

Answer

Database: A database is an organised collection of related data stored in a structured form so that it can be easily accessed, managed, and updated. It stores data in tables (rows and columns) and maintains relationships among them, allowing multiple users and applications to share the same data efficiently.

Functions of a Database Management System (DBMS):

  1. Data Definition: The DBMS allows users to define the structure of the database — creating tables, specifying fields, data types, and constraints — using languages such as DDL (Data Definition Language).

  2. Data Manipulation: It provides facilities to insert, retrieve, update, and delete data through DML (Data Manipulation Language) and query languages like SQL.

  3. Data Storage and Retrieval: The DBMS stores data on physical storage devices and retrieves it efficiently using indexing and query optimisation techniques.

  4. Data Security: It controls access to data through user accounts, passwords, and privileges, ensuring that only authorised users can view or modify data.

  5. Data Integrity and Consistency: It enforces integrity constraints (primary keys, foreign keys, validation rules) so that the data remains accurate and consistent.

  6. Concurrency Control: When many users access the database at the same time, the DBMS manages simultaneous transactions to prevent conflicts and data corruption.

  7. Backup and Recovery: It provides mechanisms to take backups and to restore the database to a consistent state after a failure or crash.

  8. Data Independence: It separates the logical view of data from its physical storage, so changes in storage structure do not affect application programs.

  9. Data Sharing and Redundancy Control: It allows multiple users and applications to share the same data while minimising duplication (redundancy) and avoiding inconsistency.

In short, a DBMS acts as an interface between users and the database, ensuring that data is stored securely, shared conveniently, and maintained accurately.

(Analyzing the risks associated with the widespread use of information technology in banking sector, describe the measures for minimizing those risks.)

Answer

Answer

The widespread use of information technology (IT) in the banking sector has brought speed, convenience and efficiency, but it has also introduced a range of serious risks. These risks must be identified and minimized through proper technical, managerial and legal measures.

Risks Associated with IT in Banking

  1. Data security risk: Customer data, passwords and account details may be hacked, leaked or misused, leading to financial loss and loss of privacy.
  2. System failure risk: Hardware breakdown, software bugs, power failure or network breakdown can stop banking services and cause huge inconvenience.
  3. Fraud and cyber-crime risk: Phishing, ATM skimming, card cloning, identity theft, ransomware and insider fraud are common in digital banking.
  4. Operational risk: Errors in data entry, wrong transactions, and dependence on a few technical staff can disturb daily operations.
  5. Reputation risk: Any major cyber-attack or data leak damages the trust and image of the bank.
  6. Legal and compliance risk: Failure to follow Nepal Rastra Bank directives, the Electronic Transactions Act and anti-money laundering rules invites penalties.
  7. Concentration and dependency risk: Over-dependence on a single vendor or data centre makes the bank vulnerable.
  8. Human resource risk: Lack of skilled IT manpower and poor awareness among staff and customers increase vulnerability.

Measures for Minimizing These Risks

  1. Strong security systems: Install firewalls, antivirus, encryption of data, multi-factor authentication and intrusion detection systems.
  2. Regular backup and disaster recovery: Keep regular off-site backups and a tested disaster recovery and business continuity plan.
  3. Access control: Use role-based access, strong passwords, biometric verification and audit trails so that only authorized staff reach sensitive data.
  4. Regular audit and monitoring: Conduct IT audits, vulnerability assessments and penetration tests, and monitor transactions continuously for suspicious activity.
  5. Employee training and awareness: Train staff on cyber-security, phishing and data-handling rules; follow a clear code of conduct.
  6. Customer awareness: Educate customers through SMS, notices and media about safe use of ATMs, mobile banking and PIN secrecy.
  7. Strong legal and regulatory compliance: Follow NRB IT guidelines, the Electronic Transactions Act, 2063 and AML/CFT provisions strictly.
  8. Vendor and outsourcing management: Select reliable vendors, sign clear service-level agreements and keep alternative arrangements.

(In which conditions a bank or financial institution may buy-back its own share? Mention.)

Answer

Conditions for buy-back of its own shares by a bank or financial institution (Nepal)

Under the Companies Act, 2063 and the directives of Nepal Rastra Bank (NRB), a bank or financial institution may buy back its own shares only in the following conditions:

  1. Authority in the Articles of Association — The Articles of Association of the bank/financial institution must expressly provide for the buy-back of its own shares.

  2. Approval of the General Meeting — A special resolution passed by the general meeting must authorise the buy-back, specifying the maximum number of shares to be bought back and the maximum price to be paid.

  3. Approval of Nepal Rastra Bank — Prior written approval of NRB is mandatory, since banks/financial institutions are licensed and regulated entities.

  4. Fully paid-up shares — Only fully paid-up shares can be bought back; partly paid-up shares cannot be purchased.

  5. Sufficient free reserves or surplus — The buy-back must be financed out of free reserves, retained earnings, or the proceeds of a fresh issue made for the purpose; it cannot be financed by borrowing or from the paid-up capital.

  6. No adverse effect on capital adequacy — After buy-back, the bank must still maintain the minimum paid-up capital and capital adequacy ratio prescribed by NRB.

  7. Solvency condition — The bank must not be insolvent, and after buy-back it must remain able to pay its debts as they fall due.

  8. Limit on quantity — The buy-back must not exceed the prescribed percentage of the total paid-up capital (ordinarily up to 5% of paid-up capital in a fiscal year, as per NRB directives), and the shares so bought must be cancelled within the prescribed period.

  9. No default status — The bank/financial institution must not be in default of any loan or financial obligation to NRB or other creditors.

  10. Compliance with securities laws — Where the bank is listed, the buy-back must also comply with the SEBON (Securities Board of Nepal) rules and the prevailing securities market regulations.

In short, buy-back is permitted only when it is legally authorised, regulator-approved, financed from free reserves, and does not weaken the bank's capital base or solvency.

(What is meant by banking offense? Discuss the problems faced in implementation of the Banking Offense and Punishment Act, 2064.)

Answer

Meaning of Banking Offense

A banking offense (बैंकिङ कसुर) is any act or omission, punishable by law, that harms the property, assets, reputation or depositors' interest of a bank or financial institution, or that obstructs the lawful business of banking. In Nepal, banking offenses are defined mainly by the Banking Offense and Punishment Act, 2064 (2008). The Act treats as offenses acts such as:

  • Taking a loan from a bank by furnishing false or forged documents, or by giving false security.
  • Misappropriation, embezzlement or illegal use of a bank's funds or a depositor's money by directors, managers or employees.
  • Obtaining credit in the name of another person without authority, or using a loan for a purpose other than the sanctioned purpose.
  • Wilful default in repayment of a loan above the prescribed limit, and transfer or concealment of mortgaged property without the bank's consent.
  • Obstructing or threatening bank staff, damaging bank property, or disclosing confidential information of a customer.
  • Operating an unlicensed banking or financial business.

The Act provides punishments such as imprisonment and fines proportionate to the amount involved, and makes the offender liable to compensate the bank. Serious offenses are investigated and prosecuted as criminal cases.

Problems Faced in Implementation of the Banking Offense and Punishment Act, 2064

  1. Lengthy legal process — Cases drag on for years in the courts. By the time a verdict comes, the offender may have transferred or consumed the assets, leaving the bank with an unrecoverable loan.

  2. Weak investigation and prosecution — Investigating agencies and public prosecutors often lack the technical expertise to handle complex financial fraud, so cases are poorly prepared and end in acquittal.

  3. Difficulty in proving intention — The Act requires proof of dishonest intention (e.g. wilful default). Distinguishing a genuine business failure from a deliberate default is hard, and offenders take shelter behind "business loss".

  4. Inadequate recovery mechanism — Even after conviction, tracing and attaching property held in the names of relatives or benami persons is difficult. The compensation ordered is often not realised.

  5. Political and executive influence — Big defaulters with political connections influence investigation and prosecution, so cases are delayed, weakened or withdrawn. This reduces the deterrent effect of the law.

  6. Inadequate legal provisions and ambiguity — Some terms such as "wilful default" and the threshold limits are not clearly defined. Punishment is not always proportionate to the size of the fraud, and the Act does not fully cover modern electronic and digital banking fraud.

  7. Weak institutional capacity — Nepal Rastra Bank, the courts and the police have limited specialised manpower and resources for financial crime. Coordination among these bodies is also weak.

  8. Lack of awareness and reporting — Customers and even bank staff hesitate to report offenses due to fear, social pressure or the belief that the case will not be decided fairly.

  9. Delay in framing rules and blacklisting — Rules, directives and the blacklisting of defaulters are not updated in time, so the Act cannot be applied promptly and uniformly.

Conclusion — The Banking Offense and Punishment Act, 2064 is an important legal tool for protecting depositors and maintaining banking discipline. However, its effectiveness is weakened by slow courts, weak investigation, political interference, unclear provisions and poor recovery. Stronger institutional capacity, clearer definitions, faster trials, strict enforcement of blacklisting and better coordination among NRB, the police and the courts are needed to make the Act work as intended.
