Chronology

A timeline of the turning points

  1. Incorporation

    United Chinese Bank incorporated.

  2. Opening

    UCB began operations.

  3. Rename

    UCB became United Overseas Bank.

  4. Friendly offer announced

    UOB and OUB announced the proposed takeover.

  5. Wholly owned

    OUB became a wholly owned subsidiary.

  6. Legal merger

    The report records the legal merger taking effect.

Start with names that look deceptively similar

United Chinese Bank, United Overseas Bank and Overseas Union Bank are not three successive names of one institution. UOB’s chronology records United Chinese Bank’s incorporation on 6 August 1935 and opening on 1 October. It became United Overseas Bank in 1965. NLB separately dates Lien Ying Chow’s founding of Overseas Union Bank to 1947 and its opening to 1949. Make two institutional lines before drawing any merger arrow. The initials UCB, UOB and OUB are compact labels, but the almost reversed words can hide a consequential error about which organisation existed and who founded it.

Distinguish an institution from its leaders

Wee Kheng Chiang led UCB’s seven-person founding group; Wee Cho Yaw later succeeded him as chairman in 1974. Lien Ying Chow founded OUB and retired as its group chairman and director in 1995. These roles do not establish who held every office during the later takeover. A founder, serving chairman, chief executive and shareholder occupy different positions in the historical account. Naming a person should be followed by the dated responsibility being described. This keeps an institutional comparison from becoming a story in which founders personally perform every subsequent corporate action.

An announced offer was one stage in 2001

UOB’s contemporaneous chairman’s statement says the banks held a press conference on 29 June 2001 to announce a friendly takeover offer, supported by OUB’s principal shareholders. It also describes a conditional offer using cash and UOB shares. Those details establish the proposal and the support described by its issuer. They should not be made to mean that all shares had already been acquired that day. Read the verb and its object together: announcing an offer is evidence of an offer announcement, while completion requires a later statement or transaction record.

Read a later milestone beside the contemporary statement

A retrospective chronology is useful for seeing decades at a glance, but its short label “acquires OUB” does not carry the same detail as the 2001 report. Conversely, the chairman’s statement emphasises the acquiring bank’s strategic achievement and is not an independent evaluation of competition or service quality. Use the sources together at the level each supports. A clean research note can contain an annual acquisition label and three dated transaction stages. It need not force every publication to use one date for all purposes, nor treat a short summary as legally exhaustive.

Original exercise: repair a misleading exhibit caption

An exhibit draft says: “OUB was UCB’s new name in 1965; the two banks legally merged when the offer was announced in June 2001.” Prepare a correction using six dated cards from the records: 6 August 1935 incorporation; 1 October 1935 opening; 1965 rename; 29 June 2001 offer; 26 October 2001 full ownership; 2 January 2002 legal merger. Assign each card to the correct institutional line or transaction stage. Then write two short captions: one explaining the 1935 bank’s identity, the other explaining the combination. Do not add a date for branch-system migration, since these records do not establish it.

Reference answer: preserve two origins and three stages

The first caption should say that United Chinese Bank was incorporated and opened in 1935, and was renamed United Overseas Bank in 1965. OUB belongs on its own line, founded in 1947 and opened in 1949. The second caption should distinguish the 29 June 2001 offer announcement, 26 October full ownership and 2 January 2002 legal merger. The original draft fails both tests: it confuses an institution’s name and collapses a process into one event. A useful conclusion is therefore precise without being overloaded. Further operational questions should be paired with dated integration or customer records rather than answered by extending the merger date beyond its evidence.
