What is Piotroski Score and how you can use it to evaluate your Investment .

 

                                           

 

                                               Piotroski Score

The Piotroski Score, also known as the Piotroski F-Score, is a financial scoring system developed by Joseph Piotroski, an accounting professor at Stanford University. The score is used to evaluate the financial strength of a company and identify potential value opportunities among financially distressed or undervalued companies.

The Piotroski Score consists of nine fundamental accounting-based criteria, divided into three categories: profitability, financial health, and operating efficiency. Each criterion is assigned a value of either 0 or 1, and the total score ranges from 0 to 9. A higher score indicates stronger financials and can be seen as a positive signal for investors.

1.    1.  Positive Net Income (Net Income > 0):

·        If a company has positive net income in the current year, it receives 1 point; otherwise, it receives 0 points.

2.       2. Positive Operating Cash Flow (Operating Cash Flow > 0):

·        If a company's operating cash flow is positive in the current year, it gets 1 point; otherwise, it gets 0 points.

3.     3.  Increasing Return on Assets (ROA):

·        If a company's ROA in the current year is higher than the previous year, it gets 1 point; otherwise, it gets 0 points.

4.   4.    Positive Change in Leverage (Long-Term Debt Ratio Decreased):

·        If a company's long-term debt ratio is lower in the current year compared to the previous year, it receives 1 point; otherwise, it receives 0 points.

5.   5.   Positive Change in Current Ratio (Current Ratio Increased):

·        If a company's current ratio (current assets / current liabilities) is higher in the current year compared to the previous year, it gets 1 point; otherwise, it gets 0 points.

6.   6.    No Issuance of New Shares:

·        If a company did not issue new shares in the current year, it receives 1 point; otherwise, it receives 0 points.

7.    7.   Increasing Gross Margin:

·        If a company's gross margin in the current year is higher than the previous year, it gets 1 point; otherwise, it gets 0 points.

8.      8. Increasing Asset Turnover Ratio:

·        If a company's asset turnover ratio in the current year is higher than the previous year, it gets 1 point; otherwise, it gets 0 points.

9.   9.    Increasing Operating Margin:

·        If a company's operating margin in the current year is higher than the previous year, it gets 1 point; otherwise, it gets 0 points.

After evaluating each of the criteria, the points are summed up to obtain the Piotroski Score. The maximum possible score is 9, indicating a financially strong company that meets all nine conditions. Conversely, a lower score may indicate weaker financial performance or financial distress.

 

Investors and analysts use the Piotroski Score as a screening tool to identify potential value opportunities or to assess the financial health of companies in their investment analysis. However, like any financial metric, it should be used in combination with other fundamental and qualitative analysis methods to make well-informed investment decisions.

 

Limitations of using Piotroski Score

While the Piotroski Score can be a useful tool for evaluating the financial strength of a company, it also has some limitations that investors and analysts should be aware of:

 

1.      Limited Scope:

 

The Piotroski Score focuses solely on financial metrics derived from accounting statements. It does not consider industry-specific factors, competitive positioning, market trends, or management quality. As a result, it may not capture the full picture of a company's overall performance and prospects.

2.     Data Accuracy and Timeliness:

 

The accuracy of the Piotroski Score depends on the accuracy and timeliness of the financial data used. Accounting errors or delays in reporting can lead to incorrect or outdated scores, which may affect investment decisions.

3.      One-Size-Fits-All Approach:

 

The same criteria are applied to all companies, regardless of their industry, size, or business model. Different industries may have varying characteristics and financial dynamics, and what is considered positive in one industry might not be relevant in another. This can limit the score's effectiveness when comparing companies from diverse sectors.

4.      Lack of Forward-Looking Analysis:

 

The Piotroski Score is based on historical financial data. It does not incorporate forward-looking information or projections about a company's future performance. Investors need to supplement the score with other methods for assessing future growth prospects.

5.      Influence of Market Sentiment:

 

The Piotroski Score focuses on accounting fundamentals, but the market's perception and sentiment about a company can influence its stock price. Even if a company has a high Piotroski Score, other factors like market sentiment, macroeconomic trends, or news events may impact the stock's performance.

6.      Small Sample Size:

 

The Piotroski Score was initially designed based on a limited sample of companies, and its effectiveness might vary across different market conditions and economic cycles. It may not work as well during periods of market disruptions or structural changes.

7.      Value Traps:

 

While a high Piotroski Score suggests a strong financial position, it does not guarantee that the stock is undervalued or will perform well in the future. Some companies with high scores may still face underlying business challenges or have declining prospects, leading to potential "value traps."

8.      Short-Term Focus:

 

The Piotroski Score is calculated using annual financial data, which means it might not be suitable for short-term traders or those interested in high-frequency trading strategies.

 

Piotroski Score in investment analysis

Using the Piotroski Score in your investment analysis can help you identify potentially attractive investment opportunities and filter out companies with weaker financial positions. Here's how you can incorporate the Piotroski Score into your investment analysis:

 

1.      Screening and Shortlisting: 

·        Begin by screening a list of potential investment candidates based on specific criteria, such as market capitalization, industry, or other qualitative factors that match your investment preferences.

·        Calculate the Piotroski Score for each company on your shortlist. You can find financial data in the company's annual reports or financial statements.

·        Focus on companies with higher Piotroski Scores, as they generally indicate stronger financial performance and better fundamental health. 

 

2.      Confirmation and Validation:

 

·        The Piotroski Score should not be used in isolation. Verify the score by analyzing the underlying financial statements, balance sheets, income statements, and cash flow statements. Look for trends and assess whether the company's financials are improving or deteriorating over time.

3.      Sector and Industry Comparison:

 

·        While the Piotroski Score provides a general assessment of a company's financial health, it is essential to compare companies within the same sector or industry.

·        Industries have unique characteristics, and some criteria may be more relevant to specific sectors. A company's performance should be evaluated relative to its peers in the same industry.

 

4.      Incorporate Qualitative Factors:

 

·        Use the Piotroski Score as one component of your investment analysis. Consider qualitative factors such as competitive advantage, management quality, growth prospects, industry trends, and economic conditions.

·        Assess how the company's products or services fit into current and future market demands.

 

5.      Future Growth Potential:

 

·        While the Piotroski Score is based on historical financial data, assess the company's potential for future growth and profitability.

·        Analyze factors like new product launches, expansion plans, market penetration strategies, and management's vision for the future.

 

6.      Risk Assessment: 

·        Evaluate the risks associated with the company's operations, industry challenges, regulatory environment, and potential disruptive factors.

·        A high Piotroski Score doesn't guarantee a risk-free investment, so it's crucial to be aware of the potential risks. 

 

7.      Diversification:

 

·        Avoid over-reliance on any single metric or scoring system. Diversify your investment portfolio across various industries, sectors, and asset classes.

·        Diversification can help mitigate risk and improve the overall performance of your investment portfolio.

Remember that no single metric can guarantee investment success, and the Piotroski Score is just one tool among many available to investors. It is essential to use it in conjunction with other fundamental and qualitative analysis methods to make well-informed investment decisions. Additionally, consider your risk tolerance and investment objectives when selecting companies for your portfolio.

 

Step-by-step guide on standard costing at short Glance

 

                                         Step-by-step guide on standard costing

 

Step 1: Identify Cost Components

First, you need to identify the cost components relevant to your business or manufacturing process. Common cost components include direct materials, direct labor, and manufacturing overhead.

Step 2: Set Standard Costs

Once you've identified the cost components, set standard costs for each one. Standard costs represent the expected or budgeted costs for producing one unit of the product. These costs can be based on historical data, engineering estimates, or industry benchmarks.

Standard Cost for Direct Materials: This includes the cost of raw materials required to produce one unit of the product.

Standard Cost for Direct Labor: This is the cost of labor required to produce one unit of the product, based on standard time and wage rates.

Standard Cost for Manufacturing Overhead: This includes the estimated overhead costs (e.g., factory rent, utilities, equipment depreciation) allocated to one unit of the product.

Step 3: Calculate Standard Cost per Unit

Next, calculate the total standard cost per unit by adding the standard costs for direct materials, direct labor, and manufacturing overhead.

 

Total Standard Cost per Unit = Standard Cost of Direct Materials + Standard Cost of Direct Labor + Standard Cost of Manufacturing Overhead

Step 4: Prepare the Production Budget

Using the standard cost per unit, prepare the production budget. This budget will show the number of units to be produced during a specific period.

 

Step 5: Record Actual Costs

As the production process takes place, record the actual costs incurred for direct materials, direct labor, and manufacturing overhead.

 

Step 6: Calculate Variances

Compare the actual costs to the standard costs to calculate the cost variances. There are several types of variances depending upon nature of organization. Some of the followings are:

 

1.      Material Price Variance: The difference between the actual cost of materials purchased and the standard cost of materials used in production.

2.      Material Usage Variance: The difference between the actual quantity of materials used and the standard quantity of materials required for production.

3.      Labor Rate Variance: The difference between the actual labor rate paid and the standard labor rate per hour.

4.      Labor Efficiency Variance: The difference between the actual labor hours worked and the standard labor hours allowed for production.

5.      Overhead Variance: The difference between the actual overhead costs incurred and the standard overhead costs applied based on production levels.

6.      Variable Overhead Variance: This variance compares the actual variable overhead costs incurred during production to the standard variable overhead costs expected based on the level of activity (e.g., machine hours, direct labor hours).

7.      Fixed Overhead Variance: The fixed overhead variance compares the actual fixed overhead costs incurred to the standard fixed overhead costs expected based on the level of activity. This variance helps analyze how well the business is managing its fixed overhead expenses.

8.      Sales Price Variance: In situations where standard costing is also used for pricing decisions, this variance compares the actual selling price per unit to the standard selling price per unit.

9.      Sales Volume Variance: This variance analyzes the difference between the actual number of units sold and the budgeted (standard) number of units expected to be sold, taking into account the standard contribution margin per unit.

10.   Mix Variance: If a company produces and sells multiple products with different profit margins, this variance compares the actual sales mix (the proportion of different products sold) to the standard sales mix.

11.   Yield Variance: Relevant in industries where products might have some inevitable waste or by-products, the yield variance compares the actual yield (output) achieved during production to the standard yield expected.

12.   Subcontract Variance: If the company has subcontracted some work, this variance compares the actual cost of subcontracting to the standard cost expected for that work.

13.   Efficiency Variance: This variance compares the actual quantity of inputs (like raw materials) used in production to the standard quantity of inputs required for the actual level of output achieved.

14.   Rate Variance (Overhead): In addition to labor rate variance, this variance applies to overhead costs and compares the actual overhead rate to the standard overhead rate.

 

Step 7: Analyze Variances

Analyze the cost variances to determine the reasons behind the differences between actual and standard costs. Variances may result from factors such as price changes, production inefficiencies, or changes in the business environment.

 

 

Step 8: Take Corrective Actions

Based on the variance analysis, take appropriate corrective actions to improve future performance. For example, if material usage variance is unfavorable, it might indicate inefficiencies in the production process that need to be addressed.

 

Step 9: Revise Standards (if necessary)

Regularly review and update the standard costs to reflect changes in the business environment, cost structures, or improvements in production processes.

 

Standard costing provides valuable insights into a company's performance and can help identify areas for improvement and cost reduction. By regularly monitoring variances and taking corrective actions, businesses can enhance their overall cost efficiency and profitability.

 

Please note that when identifying cost components in Step 1 of standard costing, it's essential to consider various factors that can affect the accuracy and relevance of the standard costs. Here are some key factors to be careful about:

 

1.      Direct vs. Indirect Costs: Distinguish between direct costs and indirect costs. Direct costs can be directly traced to a specific product or cost object, while indirect costs are incurred to support multiple products or operations. Ensure that you appropriately allocate direct and indirect costs to the relevant cost components.

 

2.      Material Specifications: Specify the quality and quantity of materials required for each unit of the product. Accurate material specifications are essential for setting appropriate standard costs and ensuring product quality.

 

3.      Labor Time and Skill Levels: Determine the standard time required to produce one unit of the product. Consider the skill levels and efficiency of the labor force when setting the standard labor cost per unit.

 

4.      Production Process Complexity: The complexity of the production process can influence the cost components. Complex manufacturing processes may involve more cost components that need to be carefully identified and managed.

 

5.      Overhead Allocation: Allocate overhead costs to the relevant cost components using an appropriate allocation basis. Common allocation bases include direct labor hours, machine hours, or activity-based costing techniques.

 

6.      Volume and Economies of Scale: Consider the impact of production volume on the cost components. Economies of scale may result in reduced costs per unit at higher production volumes, affecting the standard costs.

 

7.      Seasonality and External Factors: Take into account any seasonality or external factors that may affect the availability and cost of materials, labor, or overhead.

 

8.      Cost Behavior: Understand the behavior of costs (e.g., fixed, variable, semi-variable) and incorporate this knowledge into setting standard costs.

 

9.      Historical Data and Benchmarking: Utilize historical cost data and benchmarking against industry standards to set realistic and competitive standard costs.

 

10.   Cost Changes and Updates: Regularly review and update standard costs to reflect changes in the business environment, supplier prices, labor rates, or technological advancements.

 

11.   Management Objectives: Align the standard costs with management's objectives, whether they aim for cost leadership or focus on premium quality products.

 

12.   Legal and Regulatory Considerations: Ensure compliance with relevant laws and regulations that may impact cost components, such as labor laws, environmental regulations, and safety standards.

 

13.   Currency Fluctuations (for International Operations): For companies operating across different countries, consider currency fluctuations that may impact the costs of imported materials or exported products.

 

By carefully considering these factors, companies can develop more accurate and meaningful standard costs, providing a solid foundation for effective cost control and decision-making within the organization. Regular review and refinement of the standard costs help businesses maintain relevance and improve cost management over time.

 

Let’s take an example

 

For a chair manufacturing company in India, the cost components may include:

 

1.      Direct Materials:

 

Wood: The main material used to construct the chair frame and legs. Standard Cost: ₹150 per chair

Upholstery Fabric: Used for the chair seat and back cushion. Standard Cost: ₹100 per chair

Nails, Screws, and Glue: Fasteners and adhesives used in assembling the chair. Standard Cost: ₹30 per chair

2.      Direct Labor:

 

Carpenter's Labor: The labor cost of skilled carpenters who construct the chair frame and legs. Standard Cost: ₹200 per chair

Upholsterer's Labor: The labor cost of skilled upholsterers who assemble the chair's cushion and fabric. Standard Cost: ₹120 per chair

3.      Manufacturing Overhead:

 

a)      Factory Rent: The portion of the rent expense allocated to each chair produced. Standard Cost: ₹50 per chair

b)     Factory Utilities: The cost of electricity, water, and heating used during production. Standard Cost: ₹40 per chair

c)      Depreciation of Machinery: The depreciation expense of machinery used in the production process. Standard Cost: ₹80 per chair

The total standard cost per chair in INR would be the sum of the standard costs for direct materials, direct labor, and manufacturing overhead:

 

Total Standard Cost per Chair = (Standard Cost of Wood + Standard Cost of Upholstery Fabric + Standard Cost of Nails, Screws, and Glue) + (Standard Cost of Carpenter's Labor + Standard Cost of Upholsterer's Labor) + (Standard Cost of Factory Rent + Standard Cost of Factory Utilities + Standard Cost of Depreciation of Machinery)

 

Total Standard Cost per Chair = (₹150 + ₹100 + ₹30) + (₹200 + ₹120) + (₹50 + ₹40 + ₹80) = ₹870 per chair

 

The total standard cost per chair is ₹870, and this serves as a benchmark for cost control and performance evaluation during the manufacturing process in the Indian context. The company will compare actual costs in INR to these standard costs to identify cost variances and take appropriate actions to manage costs effectively.

 

Product Costing and factors to be considered while product costing with a practical simple example( Part 1)

 

Product costing is the process of determining the total cost involved in manufacturing a particular product. It involves identifying and quantifying all the expenses incurred in producing the product, including both direct costs (those directly attributable to the production of the product) and indirect costs (those that are not directly linked to the production process but are still necessary for the overall operation of the business).Product costing can be based on specific purpose as well. Example of product costing under different purpose may be 

1. Pricing of open Market Selling.

2. Product Mix decisions and rating of customers

3. Selling Products through Government Contracts

4. Reporting in Financial Statement

5. Market Penetration Pricing

6. Inter unit transfer

7. Valuing stock/Inventory for Insurance

8. Buy vs. Make Decision

Every purpose serves a different costing aspect. For example in Market penetration pricing management is not concerned with the fixed overhead cost allocation. They are eager to raise sale via charging only variable cost to the product making product more price competitive. In inter unit transfer relevant costing comes in picture. However these are broad concepts and we need to cover it in different blogs. For time being we are taking a simple example for calculating total product cost ignoring other purposes.   

Let's take the example of shoes to understand the factors involved in calculating product costing:

 

1.      Direct Materials: These are the raw materials that are directly used in the production of shoes, such as leather, fabric, sole materials, and accessories like laces, buckles, and zippers. The cost of each material needs to be determined based on the quantity used and their unit prices.

 

2.      Direct Labor: This includes the cost of the labor required to manufacture the shoes. It involves wages or salaries of workers directly involved in the production process, such as the cutting, stitching, and assembly of shoes.

 

3.      Overhead Costs: These are the indirect costs associated with the production process. They include expenses like factory rent, utilities, maintenance costs, depreciation of machinery, administrative expenses, and other costs that are not directly attributable to a specific shoe but are necessary for the overall production.

 

4.      Manufacturing and Operating Expenses: This includes expenses related to the manufacturing process, such as machinery and equipment maintenance, quality control, packaging, and transportation costs.

 

5.      Research and Development Costs: If the shoes are a new product or involve innovative features, research and development costs should be considered. These costs cover the expenses incurred in designing and developing the shoes.

 

6.      Marketing and Distribution Costs: These costs include expenses related to advertising, promotion, packaging design, branding, and distribution of the shoes to retail stores or customers.

 

7.      Overhead Allocation: When calculating the product costing, it is necessary to allocate the indirect costs to individual units of the product. This can be done using various methods like activity-based costing or traditional costing approaches.

 

By considering these factors and accurately calculating the costs associated with each, a comprehensive product costing analysis can be carried out. This analysis helps businesses determine the profitability of their products, set appropriate pricing strategies, and make informed decisions regarding production, cost reduction, and resource allocation.

 

 

Let’s have a practical example

1.      Direct Materials:

For manufacturing a pair of shoes, ShoeTech uses the following direct materials and their respective costs in INR:

·        Leather: ₹1,500

·        Fabric: ₹400

·        Sole materials: ₹800

·        Laces, buckles, and zippers: ₹100

 

2.      Direct Labor:

The total labor cost for manufacturing a pair of shoes is ₹1,000.

 

3.      Overhead Costs:

ShoeTech incurs various indirect costs related to production. These costs include:

 

·        Factory rent: ₹50,000 per month

·        Utilities (electricity, water, etc.): ₹10,000 per month

·        Maintenance costs: ₹5,000 per month

·        Depreciation of machinery: ₹8,000 per month

·        Administrative expenses: ₹20,000 per month

·        Manufacturing and Operating Expenses:

·        Additional expenses directly associated with the manufacturing process include:

·        Machinery and equipment maintenance: ₹2,000 per month

·        Quality control: ₹1,000 per month

·        Packaging: ₹100 per pair of shoes

·        Transportation costs: ₹10 per pair of shoes

To allocate the machinery and equipment maintenance and quality control expenses over the number of pairs produced, we need to estimate the number of pairs produced. Let's assume ShoeTech produces 1,000 pairs of shoes.

 

Now, let's calculate the cost per pair of shoes, considering the allocation of overhead costs:

 

Direct Materials:

Leather (₹1,500) + Fabric (₹400) + Sole materials (₹800) + Accessories (₹100) = ₹2,800

 

Direct Labor: ₹1,000

 

Overhead Costs Allocation per Pair:

Factory rent: ₹50,000 per month

Utilities: ₹10,000 per month

Maintenance costs: ₹5,000 per month

Depreciation of machinery: ₹8,000 per month

Administrative expenses: ₹20,000 per month

 

Total Monthly Overhead Costs = Factory rent + Utilities + Maintenance costs + Depreciation of machinery + Administrative expenses

Total Monthly Overhead Costs = ₹50,000 + ₹10,000 + ₹5,000 + ₹8,000 + ₹20,000 = ₹93,000

 

Machinery and Equipment Maintenance Allocation per Pair = Machinery and equipment maintenance / Number of pairs produced

Machinery and Equipment Maintenance Allocation per Pair = ₹2,000 / 1,000 pairs = ₹2

 

Quality Control Allocation per Pair = Quality control / Number of pairs produced

Quality Control Allocation per Pair = ₹1,000 / 1,000 pairs = ₹1

 

Manufacturing and Operating Expenses Allocation per Pair:

Machinery and equipment maintenance (₹2 per pair) + Quality control (₹1 per pair) + Packaging (₹100 per pair) + Transportation costs (₹10 per pair) = ₹113

 

Total cost per pair of shoes = Direct Materials + Direct Labor + Overhead Costs Allocation per Pair + Manufacturing and Operating Expenses Allocation per Pair

 

= ₹2,800 + ₹1,000 + ₹93 + ₹113

 

= ₹4,006

 

Therefore, the cost per pair of shoes manufactured by ShoeTech, correctly allocating the overhead costs and the expenses over the estimated number of pairs produced, is ₹4,006.

 Now let's talk about what are factors that needs to be in mind while calculating product costing

When calculating product costing, there are several factors to consider. Here are some key factors to keep in mind:

 

1.      Direct Materials: Identify and quantify the costs of the raw materials directly used in the production of the product.

 

2.      Direct Labor: Determine the labor costs associated with the production process, including wages, benefits, and any additional labor-related expenses.

 

3.      Overhead Costs: Consider all indirect costs associated with the production process, such as factory rent, utilities, maintenance, depreciation, administrative expenses, and other overheads.

 

4.      Manufacturing and Operating Expenses: Account for additional expenses directly related to manufacturing, including machinery maintenance, quality control, packaging, and transportation costs.

 

5.      Research and Development Costs: Include any costs incurred for research, development, and innovation of the product.

 

6.      Marketing and Distribution Costs: Take into account expenses related to marketing, advertising, packaging design, branding, and distribution of the product.

 

7.      Volume and Scale: Consider the production volume and scale of operations, as costs may vary depending on the quantity produced.

 

8.      Cost Allocation Methods: Determine the most appropriate method for allocating overhead costs to the product, such as traditional costing, activity-based costing, or other suitable approaches.

 

9.      Costing Period: Ensure that the costs are allocated correctly for the specific period under consideration.

 

When calculating product costing, it's essential to be aware of potential errors that cost accountants may make. Here are a few common errors to watch out for:

 

1.      Incorrect Cost Classification: Misclassifying costs as direct or indirect, leading to inaccurate allocation and incorrect product costing.

 

2.      Incomplete Cost Consideration: Overlooking certain costs or not considering all the relevant factors that contribute to the overall cost of production.

 

3.      Overlooking Cost Drivers: Failing to identify the key cost drivers that influence the cost of production, resulting in inaccurate cost allocation.

 

4.      Over- or Under-Absorption of Overhead Costs: Improper allocation of overhead costs can lead to distorted product costs, affecting pricing decisions and profitability analysis.

 

5.      Inaccurate Volume Assumptions: Using incorrect or outdated volume assumptions can lead to inaccurate cost per unit calculations.

 

6.      Failure to Update Cost Data: Not updating cost data regularly can result in outdated and inaccurate product costing information.

 

7.      Ignoring Variable and Fixed Costs: Neglecting to distinguish between variable costs (those that vary with production volume) and fixed costs (those that remain constant regardless of volume), leading to inaccurate cost analysis.

 

8.      Lack of Standardization: Failing to establish standardized cost calculation methods and consistently applying them across products, resulting in inconsistent and unreliable product costing.

 

To ensure accurate product costing, it's important to carefully review the calculations, consider all relevant costs, update cost data regularly, and implement appropriate cost allocation methods while avoiding the common errors outlined above.
