HOW TO WRITE PHP SCRIPTS The main points to note about switch are as follows: • • • • • The expression following the case keyword must be a number or a string. You can t use comparison operators with case. So case 100: isn t allowed. Each block of statements should normally end with break, unless you specifically want to continue executing code within the switch statement. You can group several instances of the case keyword together to apply the same block of code to them. If no match is made, any statements following the default keyword are executed. If no...

In this chapter, we consider both the if and switch conditional constructs that control whether a statement list is executed. Because the if constructs use logical expressions to determine their course of action, we begin with logical expressions.

The CECL revised accounting standard for credit loss provisioning is intended to represent a forward-looking and proactive methodology that is conditioned on expectations of the economic cycle. In this study we analyze the impact of several modeling assumptions - such as the methodology for projecting expected paths of macroeconomic variables, incorporation of bank-specific variables or the choice of macroeconomic variables – upon characteristics of loan loss provisions, such as the degree of pro-cyclicality.
