If there is a cash problem there will be an obvious give away. If they announce they are starting a DRP with the negativity around cash ATM run for the hills.
They are paying out a decent cash dividend. Are they borrowing to cover the dividend? Is debt getting out of control. No to both.
If debt rises significantly without explanation I would be worried. Come to think of it Companies as acquisitive as CTD usually have mountains of debt or mountains of shares on issue. CTD has neither. Something is surely wrong!!
According to Simply Wall Street:
Level of debt to net worth is 10.9% which is very good. 5 years ago it was 0.5%. So it has risen but not to anywhere alarming levels.
Debt is well covered by operating cash flow (135.9%)
Interest coverage is an excellent 42.3 x EBIT.
The other giveaway to watch for will be insider selling. If there is a cash problem and an insider cover up you can bet there will be insider selling - its a sure thing.
According to Simply Wall Street there has been no recent insider selling. On the other hand insiders have spent around $6.4 mill on purchasing shares.
I will be watching closely for selling before the next report.
The reality is if cash is lost forever because it is never converted it will flow through to lower profits. So watch for downgrades. If cash is repeatedly lost forever then eventually debt will have to increase to cover it and or we will see a DRP to conserve cash. 
We have a situation where full year profits are expected to see a handy % increase. So watch for downgrades.
If the Business is bleeding cash via poor cash conversion then the ABSOLUTE giveaway will be a second consecutive big miss next report. So again watch for insider selling. If it is timing differences as claimed then the issue should pretty well sort itself out full year.
They say its paying bills in one period and collecting cash in the next period. I forget the amounts involved but cash accounting is different to P/L and Balance sheet Accrual accounting. With cash accounting it is what it is, when it is. So you will see a shortfall if it is what they say.
Anyway I am keeping an open mind as like all investors I have been caught out a few times to many.
I will have to have a look back at other reports for Cash Conversion when I get around to it. Does anyone know how it has been in the past?
