(d) Option to Produce Business Records.
If the answer to an interrogatory may be derived or ascertained from the business
including electronically stored information, of the party upon whom the interrogatory has
been served or from an examination, audit or inspection of those business records, including
a compilation, abstract or summary thereof, and the burden of deriving or ascertaining the
answer is substantially the same for the party serving the interrogatory as for the party
served, it is a sufficient answer to such interrogatory to specify the records from which the
answer may be derived or ascertained and to afford to the party serving the interrogatory
reasonable opportunity to examine, audit or inspect such records and to make copies,
compilations, abstracts or summaries. A specification must be in sufficient detail to permit
the interrogating party to locate and to identify, as readily as can the party served, the records
from which the answer may be ascertained.

(2) giving the interrogating party a reasonable opportunity to examine and audit the records and to make copies, compilations, abstracts, or summaries.
