The definition for CMD says the following:

PRD wrote:

A creature's CMD is determined using the following formula:

CMD = 10 + Base attack bonus + Strength modifier + Dexterity modifier + special size modifier

The special size modifier for a creature's Combat Maneuver Defense is as follows: Fine –8, Diminutive –4, Tiny –2, Small –1, Medium +0, Large +1, Huge +2, Gargantuan +4, Colossal +8. Some feats and abilities grant a bonus to your CMD when resisting specific maneuvers. A creature can also add any circumstance, deflection, dodge, insight, luck, morale, profane, and sacred bonuses to AC to its CMD. Any penalties to a creature's AC also apply to its CMD. A flat-footed creature does not add its Dexterity bonus to its CMD.

Now, as has been pointed out, the AC bonus from Defending is untyped. As such, it is not a circumstance, deflection, dodge, insight, luck, morale, profane or sacred bonus. Seeing as the above-referenced rule does not include any sort of "all [BLAH], such as..." language, it seems reasonable to conclude that the list of applicable bonuses is precise, rather than representative; i.e., only the types of AC bonuses listed can be transferred to CMD.

Rebuttals?

This point has been covered effectively. There is no rebuttal for this point. That is where the RAW/RAI discussion of this topic truly comes into play. The Touch AC point is the only possible explanation for the RAI being that defending applies to CMD while by RAW it isn't a question but a glaring omission that makes no sense.

Rebuttal: Untyped applies to Touch AC, which ignores Armor/NA/Shield bonuses... As already mentioned up-thread.

Functioning identical to Armor bonus would expected to be classed as Armor bonus.
There are ways to make it stack if that is intended, such as ´increases your Armor Bonus by X...´.

I would expect, if it were to apply as an enhancement bonus, for it to behave in such a way that the wording would be, "As a swift action you may shift any amount of a defending weapons enhancement bonus to your armor" or some such way... i've never been good with rule wording but you get the point. Which is why I would have to agree with quandary's rebuttal.

That has been my point. The entire idea behind defending is to help your defenses and I couldn't see any reason that it wouldn't apply other than the oversight of its omission in text. I also thought it might have been fixed somewhere along the line and I just missed it. Thanks for the opinions though. I always like having people agree with me XD

This is an argument my DM and I have been having for sometime. Whether the bonus from a defending weapon applies to CMD like many other bonuses. He says since its a general bonus with no real type and therefore not on the list of things that apply to CMD and AC that it doesn't. I argue that it was an oversight and should apply. Any thoughts?

Come on. I know this thread has been 'dead' so to speak for some time but noone noticed the new post? I could really use an answer on this.

So I have a new question on the topic of Defending weapons that I didn't see addressed here. Does the Defending bonus apply to CMD as well as AC or does the generic/un-typed bonus fall out of the scope of bonuses that are applicable to both such as Dodge, Deflection, Luck, etc...

This question has been a thorn in my side for months now with one of my characters as my DM and I have been arguing the possibility since I shelled out for a +5 Defending Gauntlet.
