ZURICH, June 12 (Reuters) - UBS Group's takeover of Credit Suisse, arranged by the Swiss authorities to stave off a broader banking crisis, became official on Monday.
The closing of the tie-up marks the final chapter for the 167-year old institution after years of scandals and missteps eroded customer confidence and brought the lender to the edge.
Here are some key events in the run-up to the biggest banking deal since the global financial crisis. FEBRUARY
Feb. 28 - Swiss regulators rebuke Credit Suisse for "serious" failings in its handling of a multi-billion business with now defunct financier Greensill, the third such public censure in two years.
MARCH
March 9 - Credit Suisse delays its annual report after a last minute call by U.S. regulators raised questions about its earlier financial statements.
March 13 - Credit Suisse shares hit a record low after the entire banking sector sells off in the wake of the collapse of Silicon Valley Bank.
March 14 - Publishing its delayed 2022 annual report, Credit Suisse says it had identified "material weaknesses" in internal controls over financial reporting and not yet stemmed customer outflows.
March 15 - The Swiss National Bank pledges to fund Credit Suisse with liquidity "if necessary" - the first such move for a big bank since the global financial crisis. Earlier, Credit Suisse's largest shareholder - Saudi National Bank - said it would not increase its stake, sending the lender's shares plunging by a fifth.
March 16: Credit Suisse says it intends to borrow up to 50 billion Swiss francs ($55.40 billion) from the central bank.
March 19: An emergency rescue of Credit Suisse, brokered by the Swiss government, central bank and financial regulator, is announced. Under the deal, UBS agrees to buy Credit Suisse for a knockdown price of 3 billion Swiss francs in stock and assume up to 5 billion francs in losses. Detailing the events later in a regulatory filing UBS said it was rushed into a deal it did not want.
March 20 - The rescue triggers a political backlash, with Swiss parties on the right and left warning about the huge risks and the size of the combined entity.
March 21 - Swiss authorities impose curbs on bonus payments for Credit Suisse employees.
March 23: Switzerland's financial market regulator FINMA defends its decision to impose steep losses on Credit Suisse bondholders, calling the decision legally watertight.
March 29 - UBS rehires former CEO and turnaround specialist Sergio Ermotti to steer the takeover.
APRIL

April 4 - Credit Suisse chairman Axel Lehmann apologises to investors for taking the bank to the brink of bankruptcy at the bank's final shareholder meeting.
April 5 - The Swiss government orders Credit Suisse to cancel or cut all outstanding bonus payments for senior management.
- Separately, UBS executives call the takeover a "Herculean task," but tell shareholders it will succeed.
April 11 - The Swiss Bank Employees Association demands a freeze on job cuts at both banks until the end of 2023. Swiss media had earlier reported up to 11,000 jobs could be lost in Switzerland.
April 12 - Switzerland's parliament rejects the government's aid for the merger in a largely symbolic vote.
April 15 - The Federal Reserve approves UBS's acquisition of the U.S. subsidiaries of Credit Suisse.
April 24 - Credit Suisse says 61 billion Swiss francs in assets had left the bank in the first quarter, as it reported what were probably its last ever quarterly results.
April 26 - Switzerland's Federal Administrative Court says it has received "several hundred" claims against the country's financial regulator after it wrote off the value of Credit Suisse's AT1 bonds.

June 8 - Switzerland's parliament formally approves a special commission to investigate Credit Suisse collapse and rescue.
