Can X13 Performance Bond be included in NEC4 Option A contract alongside X4 Ultimate Holding Company Guarantee
Yes, one is an “on demand bond” covering company insolvency (X13). The other is the “ultimate parent company” acting as a guarantor to the performance of the subsidiary company. If the subsidiary went into liquidation you would call on the guarantor, if the head company went into liquidation you would call upon the performance bond. You would obviously not use X.4 if there are no subsidiaries. I believe you can have both X options in the same contract, happy to be corrected if this is not the case. Contract Date Part one of NEC 4 (Option A) would support this view too.
