## Management of Marketable Securities
### Purpose
Working capital needs fluctuate, so surplus cash is invested in short-term securities that provide both liquidity and returns. When cash is needed, the securities are liquidated.
### Key Principles for Selection
1. Safety — minimum risk is preferred, since liquidity (not high return) is the priority.
2. Maturity — investments should match expected cash needs; short-term securities carry less risk.
3. Marketability — securities must be easily and quickly convertible into cash without loss of value.
(Memory aid: S-M-M — Safety, Maturity, Marketability.)
