The related activities described in section 3(r) as included in the
statutory enterprise are those performed for a ``common business
purpose.'' (See the comprehensive discussion in 29 CFR part 776.) The
term ``common business purpose'' as used in the definition does not have
a narrow concept and is not intended to be limited to a single business
establishment or a single type of business. As pointed out above,
retailing, wholesaling and manufacturing may, under certain
circumstances be engaged in for a ``common business purpose.'' (See
Sec. 779.209.) An example was also cited where retailing and
construction were performed for a common business purpose. (See
Sec. 779.206.) On the other hand, it is clear that even a single
individual or corporation may perform activities for different business
purposes. (See Sec. 779.211.) Thus the reports of the House of
Representatives cite, as an example of this, the case of a single
company which owns several retail apparel stores and is also engaged in
the lumbering business. It concludes that these activities are not part
of a single enterprise. (H. Rept. 75, 87th Cong.,1st Sess., p. 7 and H.
Rept. 1366, 89th Cong. 2d Sess., p. 9.)
