Where should periods be placed in this sentence:

"XYX signed the contract with ABDC Ltd (ABCL)."

Should there be a period after Ltd, or is just one period after the paranthesis OK?

  • Welcome to ELU. You're asking about how to write abbreviations - I think this would be better asked at the English Language Learners site. – JHCL Oct 16 '15 at 21:44
  • maybe i was not clear ... I am not asking about abbreviations. My question is simple. I have a company name that ends with, say, Inc (period needed) or Ltd (period) - now after mentioning the company name, I am putting the acroyn of the company in paranthesis and the sentence ends immediately.... So to repeat my question --- and this is just an example -- "The California-based Berkeley Pet Society on Friday signed a contract with Texas Lovers of Pet, Inc. (TLPI). Do i use a period after Inc or after (TLPI) or after both? – user143091 Oct 16 '15 at 22:26
  • Then the sentence doesn't end immediately after the abbreviation, it ends after the parenthesis. Why would't you use a period wherever it's required? (NB - possibly a duplicate of this question). – JHCL Oct 16 '15 at 22:32

    I think you should edit the question to clarify. Perhaps include in full the options you're considering. – JHCL Oct 16 '15 at 22:48

This is a matter of using a proper name with a style of punctuation. Your first guide should be the usage preferred by the named entity itself. Use whatever Acme Brocade, Decoration, and Costumers, Limited calls itself, whether that be

ABDC, Ltd.

or other combination of their choosing.

Style guides differ. Oxford Dictionaries says that initialisms like ABDC and NASA don't use periods and neither do abbreviations using the the first and last letter of the word abbreviated. That means

Mr Dr Ltd and US

They do note some American exceptions (e.g, U.S.). The Chicago Manual of Style, however, puts the period after Mr. and Dr.

Chicago recommends dropping an abbreviating period at the end of a sentence and dropping all punctuation except terminal (i.e., sentence ending) punctuation before a closing parenthesis. If the company or your style guide required a period -- Ltd. -- then

XYX signed the contract with ABDC, Ltd.
XYX signed the contract with ABDC, Ltd. (ABCL).
XYX signed the contract with the company (ABDC Ltd).


Periods as abbreviation and acronym signifiers are not necessary anymore and lately. I think it's a cultural thing because we see the redundancy with N.A.S.A. and after decades we get tired of being told "this stands for something else".
