CAPITAL EXPENDITURES

Definition

Capital expenditures (CapEx) are funds used by a business to acquire, upgrade, or maintain long-term physical assets such as property, equipment, or technology. CapEx is not expensed immediately on the income statement but capitalized on the balance sheet and depreciated or amortized over time.

Origins

The term comes from “capital,” referring to long-term assets, and “expenditures,” meaning spending. CapEx accounting principles were formalized with the evolution of accrual accounting and are guided today by GAAP, IFRS, and tax regulations worldwide.

Usage

Capital expenditures are essential in:

• Financial modeling: Used to forecast depreciation and asset value.

• Cash flow analysis: Represent cash outflows in investing activities.

• Valuation models: Affect free cash flow (FCF), which drives DCF valuation.

• Strategic planning: Reflect business investment in capacity or efficiency.

• Tax planning: CapEx is depreciated over time, impacting taxable income.

   

How CapEx Works

When a company spends on long-term assets, that spend is capitalized and recorded on the balance sheet, not immediately expensed. The value of the asset is then reduced over time through depreciation (tangible assets) or amortization (intangible assets).

CapEx Lifecycle:

• Initial Investment → Purchase or build a long-term asset.

• Capitalization → Record the asset as a non-current asset.

• Depreciation/Amortization → Allocate the cost over its useful life.

• Disposal → Derecognize the asset upon sale or obsolescence. 

Key Takeaway

• CapEx is used for long-term asset acquisition and improvement.

• It increases fixed assets on the balance sheet.

• Not an immediate expense, but gradually reduces net income via depreciation.

• Affects free cash flow, profitability, and valuation metrics.

Types & Variations

1. Growth CapEx

• Used to expand capacity or enter new markets.

• Example: Building a new manufacturing facility.

2. Maintenance CapEx

• Required to sustain current operations.

• Example: Replacing old machinery or roof repairs.
  
  

3. Tangible CapEx

• Physical assets like land, buildings, equipment, vehicles.
  
  

4. Intangible CapEx

• Long-term investments in software, patents, licenses (sometimes treated separately under accounting standards).

Context in Financial Modeling

Capital expenditures are core to:

• DCF valuation models:

  $$\text{Free Cash Flow to Firm (FCFF)} = \text{EBIT} (1 - \text{Tax Rate}) + \text{D\&A} - \text{CapEx} - \Delta \text{Working Capital}$$

• Forecasting asset base and depreciation

• Measuring reinvestment rate and growth potential

• ROIC analysis: CapEx influences how efficiently a company allocates capital.

   

Nuances & Complexities

• CapEx vs. OpEx: CapEx is capitalized; OpEx (Operating Expenses) are expensed immediately.

• Capitalization Criteria: Must have a useful life > 1 year and provide economic benefit.

• Industry Differences: Utilities and telecoms often have high CapEx; software firms less so.

• Timing Impact: Large CapEx projects may take years to yield returns.

Mathematical Formulas

1. From Cash Flow Statement:

{CapEx} = {Change in Net PP&E} + {Depreciation}

• Where: PP&E = Property, Plant, and Equipment

2. Free Cash Flow (FCF):

FCF= Operating Cash Flow − CapEx

 $$\text{Cash Flow from Ops} = \text{Net Income} + \text{Non-Cash Expenses} + \text{Changes in Working Capital}$$

Real-World Applications

Example 1: Apple Inc.

In 2023, Apple spent over $11 billion in CapEx, mostly on data centers, production equipment, and corporate infrastructure, indicating long-term investment in capacity and innovation.

Example 2: Utility Sector

Electric utilities like Duke Energy regularly invest in infrastructure upgrades and renewable energy projects, CapEx-heavy operations with high regulatory oversight.

Example 3: Startups & SaaS

While CapEx is minimal in SaaS companies, some classify software development costs or capitalized R&D as CapEx under certain accounting standards.
