# Is Cash Flow Positive Starhub Ltd A Buy?

“Cash, though, is to a business as oxygen is to an individual: never thought about when it is present, the only thing in mind when it is absent. When bills come due, only cash is legal tender. Don’t leave home without it.”

— Warren Buffett

As we search for positive signs in a new company, the cash flowing through the firm may be one thing worth looking up. In particular, the cash conversion cycle of a company may be of interest to the Foolish investor.

Turning goods into cash

Simply said, the cash conversion cycle is the number of days it takes for a company to 1) convert cash in the bank into inventory, 2) sell that inventory, and 3) receive the cash from the sale. The shorter the cycle goes, the better.

To learn how to calculate the cash conversion cycle, go here.

Let’s run telecommunications outfit Starhub Ltd (SGX: CC3) through this calculation today. We will be using the figures from the company’s financial year ended 31 December 2014 in this case.

We start with the Days Inventory Outstanding (DIO) metric. DIO is the number of days that it takes for a company to sell its entire inventory. Generally speaking, the lower the number of days, the more effective the company’s inventory management is.

Below is a summary table with all the relevant figures.

Next up, we have the Days Sales Outstanding (DSO) figure. DSO represents the amount of time it takes the company, on average, to receive money after it has sold a good or service. Having a lower DSO usually indicates that a company is good at credit management.

Finally, we come to the Days Payable Outstanding (DPO), which is the number of days it takes a company to pay its suppliers after their products have arrived. In general, having a longer payment term is better for a company.

Pulling it together

The cash conversion cycle can now be put together by adding the DIO with DSO and subtracting the DPO. Doing so would give Starhub a cash conversion cycle of 265 days for the financial year ended 31 December 2014 (16 + 25 – 306 = -265).

It’s notable that Starhub is able to put off paying its suppliers (306 days!) for far longer than it takes to collect its payment from its customers (25 days). In this case, it’s the DPO which makes a significant difference to the cash conversion cycle at Starhub.

In all, Starhub’s cash conversion cycle of -265 days would mean that less cash needs to be tied up in the daily operations of its business. This also could be the reason behind Starhub’s long history in generating positive free cash flow.

Over time, tracking the changes in the cash conversion cycle of a company may help the Foolish investor understand the business changes that the company makes and whether those changes helps bring in the cash faster.

With that, the Foolish investor would be in a better position to decide if Starhub’s current share price provides an appropriate margin of safety and whether it fits into his or her portfolio.
