The Bridge Effect in Price Determination Reports

In price determination reports, the move from enterprise value to equity value is made through a bridge adjustment covering net debt and non-operating items. The bridge is not a standalone method; it reconciles different value categories.

Thirteen-Week Rolling Cash Budget

A thirteen-week rolling cash budget shows, week by week over roughly the next three months, expected cash inflows and outflows and when financing needs may arise. It is a short-term liquidity management tool.

What Does Ageing of Receivables Mean?

Ageing of receivables classifies trade receivables by due date and days overdue. What matters is not the total balance, but how much is overdue and carries collection risk.

When Do Firms in Türkiye Experience Cash Squeezes Most Often?

Cash squeezes are not driven by tax dates alone; interest rates, banks’ appetite to lend, the exchange rate, inventory costs, collection periods, and sales tempo matter together. What helps is tracking which market conditions widen the cash gap.

The Hidden Rules of Getting Bank Credit

In bank lending decisions, what matters most is not only the documents submitted but the risk profile the firm presents. A strong application should include a short, coherent credit story supported by consistent data.

Wealth is not a one-off stroke of luck. It is the accumulated result of hundreds of sound financial decisions (a sequence of principle-consistent behaviours) over many years—starting with how you relate to money, not with a stock tip.

Challenges in Determining Company Value in Türkiye

In Türkiye, company valuation becomes more complex because of inflation, interest-rate and exchange-rate uncertainty, limited access to sector data, and an underdeveloped financial-planning culture. Key challenges and calculation frameworks.

Interest is not merely the price of using capital; it is also a historical institution that reflects relations of power, risk, and justice—from agrarian societies to Islamic law.

Fraudsters Draw Their Energy from Greed

The energy that sustains fraud often springs from excessive human expectations. Financial literacy, healthy scepticism, and patience—alongside law and punishment—are among the strongest defences against fraud.

Would Finance Exist Without Money?

The essence of finance is not money but deciding how scarce resources are used over time. Without money, saving, investment, debt and risk-sharing would still exist—only the instruments would differ.

Why Finance Is Not Only a Matter for Finance Professionals

Finance is the discipline of allocating scarce resources between present needs and future goals. Financial awareness acquired at university can shape living standards long after graduation—not only for economics or business students, but for engineers, lawyers, physicians, and aspiring entrepreneurs alike.
