When a noun ends in s, form the singular possessive by adding an apostrophe s ('s):

When a noun ends in s, form the plural possessive by adding only an apostrophe ('):
Examples:
the ladies handbags = the ladies' handbags

Please note that the possessive is used even when the noun modified is not expressed:
Examples:
