The uniform stacking of layers of nacre below the surface of the shell also causes interference effects that contribute to the iridescent colors. The pearl derives its iridescence from the diffraction and interference of white light, caused by tiny overlapping platelets of calcium carbonate.
like assets many liabilities are intuitive however there may be some instances where a liability needs to be recorded although the company may not have perceived it as one an example of this would be a finance lease where there is no present obligation to pay the future lease payments
A liability is an obligation that must eventually be paid, and, hence, it is a claim on assets. The owner's equity in a bank is often referred to as bank capital, which is what is left when all assets have been sold and all liabilities have been paid. A bank uses liabilities to buy assets, which earns its income.
