Collar options strategy trade

[zirjeo]

New to options not sure if the following trade is actually a collar or not, trying to make it as near to a costless collar as possible but I have different expirations for the put and call.

Stock(CRUS) is @ $16.1, bought 100 shares. Long.

Does it make sense to do the following...

Buy a Sept. $16 Put. Premium is $1.45

Sell a Dec. $20 Call. Premium is $1.05
The Sep. $20 Call is only a $0.4 premium.

I really don't plan on holding it past Sep. anyhow. But wanted the premiums to offset eachother.

Seeing it has a different expiration, Im not sure if this is still a Collar or if this is even an acceptable method?

thanks in advance
