====== Profit and Loss (P&L) Statement ======
The Profit and Loss (P&L) Statement (also known as the '[[Income Statement]]') is one of the three core financial statements that public companies are required to release. Think of it as a financial movie of a company's performance over a specific period, such as a quarter or a full year. It starts with the company's total sales and systematically subtracts all the costs and expenses incurred to generate those sales. The final scene of this movie reveals the grand finale: the company's profit or loss. For an investor, the P&L statement is a report card that answers the most fundamental question: "Did the business actually make any money?" It tells a story of how efficiently a company can turn its sales into real profit, providing crucial clues about its operational health, pricing power, and management effectiveness. Reading it helps you understand the sources of a company's profitability, not just the final number.
===== How to Read a P&L Statement =====
The P&L statement is elegantly simple in its structure. It flows logically from top to bottom, with each line item telling part of the company's financial story for the period.
==== The Story from Top to Bottom ====
Imagine you're reading a summary of a business's year. The P&L presents the plot points in a specific order:
  * **Revenue (Sales):** This is the very first line, often called the [[Top Line]]. It represents the total amount of money a company generated from selling its products or services before any expenses are taken out. It's the starting point for everything.
  * **Cost of Goods Sold (COGS):** These are the direct costs of producing the goods or services that were sold. For a car company, this would include the steel, tires, and factory labor. For a software company, it might be server costs and technical support staff salaries.
  * **Gross Profit:** This is what's left after you subtract COGS from Revenue (Revenue - COGS = [[Gross Profit]]). It's a key indicator of how efficiently a company produces what it sells. A high [[Gross Margin]] (Gross Profit / Revenue) is a fantastic sign.
  * **Operating Expenses (OpEx):** These are all the other costs required to run the business that aren't directly tied to production. Think of marketing campaigns, salaries for the CEO and administrative staff, and research and development (R&D) costs.
  * **Operating Income:** This is calculated by subtracting [[Operating Expenses]] from Gross Profit. [[Operating Income]] (often called [[EBIT]], for Earnings Before Interest and Taxes) tells you how much profit the company made from its core business operations. It’s a pure measure of business performance, ignoring financing decisions and tax policies.
  * **Interest and Taxes:** Next, the company subtracts any interest it paid on its debts and the taxes it owes to the government.
  * **Net Income:** And here we are, the grand finale! This is the famous [[Bottom Line]]. It's the profit that remains after //all// expenses—COGS, OpEx, interest, and taxes—have been paid. This is the amount of money the company has truly earned, which can then be reinvested back into the business or paid out to shareholders as [[dividends]].
===== A Value Investor's Perspective =====
For a [[Value Investing]] practitioner, the P&L statement is far more than a simple scorecard. It’s a treasure map that, when read carefully and over time, can reveal a company's underlying economic strength and competitive advantages.
==== Beyond the Bottom Line ====
A smart investor doesn't just glance at the [[Net Income]]. They dig deeper to understand the //quality// of those earnings.
  * **Consistency is Key:** A single great year could be a fluke. A value investor looks for a consistent history of growing revenue and, more importantly, growing profits. Is the company steadily improving, or was its recent success due to a one-time event like selling a factory?
  * **Mighty Margins:** The P&L is where you calculate a company's [[Profit Margin]]s. Analyzing the [[Operating Margin]] (Operating Income / Revenue) and [[Net Margin]] (Net Income / Revenue) over several years reveals a lot. High and stable (or rising) margins suggest the company has strong pricing power and a durable competitive advantage, what [[Warren Buffett]] calls a [[Moat]]. A company that can consistently keep a large slice of every dollar in sales is a business worth owning.
  * **Read the Trilogy:** The P&L statement never tells the whole story on its own. It must be analyzed alongside the [[Balance Sheet]] (a snapshot of what the company owns and owes) and the [[Cash Flow Statement]] (which tracks the actual cash moving in and out).
==== The P&L vs. The Other Financial Statements ====
A simple way to distinguish the three main financial statements is through an analogy:
  * **The P&L Statement** is a //movie//, showing performance over a period of time.
  * **The Balance Sheet** is a //photograph//, showing financial health at a single point in time.
  * **The Cash Flow Statement** is the //detective// that follows the cash. Because of [[Accrual Accounting]], the P&L can show a profit even if the company hasn't collected the cash from its customers yet. The Cash Flow Statement confirms whether the profits reported on the P&L are translating into real cash in the bank—and for an investor, cash is king.
