Transactions With Related Parties [Abstract]

TRANSACTIONS WITH RELATED PARTIES

NOTE 34 - TRANSACTIONS WITH RELATED PARTIES

In addition to affiliates and associated entities, the Bank’s “related parties” include its “key personnel” from the executive staff (members of the Bank’s Board of Directors and Managers of Banco Santander-Chile and its affiliates, together with their close relatives), as well as the entities over which the key personnel could exercise significant influence or control.

The Bank also considers the companies that are part of the Santander Group worldwide as related parties, since all of them have a common parent, i.e., Banco Santander S.A. (located in Spain).

Transactions between the Bank and its related parties are specified below, facilitate comprehension purposes, we have divided the information into four categories:

Santander Group Companies

This category includes all the companies that are controlled by the Santander Group around the world, and hence, it also includes the companies over which the Bank exercises any degree of control (affiliates and special-purpose entities).

Associated companies

This category includes the entities over which the Bank, in accordance with section b) of Note 1 to these Financial Statements, exercises a significant degree of influence and which generally belong to the group of entities known as “business support companies”.

Key personnel

This category includes members of the Bank’s Board of Directors and managers of Banco Santander-Chile and its affiliates, together with their close relatives.

Other

This category encompasses the related parties that are not included in the groups identified above and which are, in general, entities over which the key personnel could exercise significant influence or control.

The terms for transactions with related parties are equivalent to those which prevail in transactions made under market conditions or to which the corresponding considerations in kind have been attributed.

Market risk trading portfolio, description				For the Bank, the VaR estimate is made under the historical simulation methodology, which consists of observing the behavior of the profits and losses that would have occurred in the current portfolio if the market conditions for a given historical period had been in force, in order to infer the maximum loss on the basis of that information, with a given degree of confidence. The methodology has the advantage of precisely reflecting the historical distribution of the market variables and not requiring any assumptions regarding the distribution of specific probabilities. All the VaR measures are intended to determine the distribution function for a change in the value of a given portfolio, and once that distribution is known, to calculate the percentile related to the necessary degree of confidence, which will be equal to the value at risk by virtue of those parameters. As calculated by the Bank, the VaR is an estimate of the maximum expected loss of market value for a given portfolio over a 1–day horizon, with a 99.00% confidence level. It is the maximum 1–day loss that the Bank could expect to experience in a given portfolio, with a 99.00% confidence level. In other words, it is the loss that the Bank would expect to experience only 1.0% of the time. The VaR provides a single estimate of market risk which is not comparable from one market risk to another. Returns are calculated through the use of a 2–year time window or at least 520 data points obtained since the last reference date for calculation of the VaR going backward in time.	For the Bank, the VaR estimate is made under the historical simulation methodology, which consists of observing the behavior of the profits and losses that would have occurred in the current portfolio if the market conditions for a given historical period had been in force, in order to infer the maximum loss on the basis of that information, with a given degree of confidence.

All the VaR measures are intended to determine the distribution function for a change in the value of a given portfolio, and once that distribution is known, to calculate the percentile related to the necessary degree of confidence, which will be equal to the value at risk by virtue of those parameters. As calculated by the Bank, the VaR is an estimate of the maximum expected loss of market value for a given portfolio over a 1–day horizon, with a 99.00% confidence level. It is the maximum 1–day loss that the Bank could expect to experience in a given portfolio, with a 99.00% confidence level. In other words, it is the loss that the Bank would expect to experience only 1.0% of the time. The VaR provides a single estimate of market risk which is not comparable from one market risk to another. Returns are calculated through the use of a 2–year time window or at least 520 data points obtained since the last reference date for calculation of the VaR going backward in time.

Capital adequacy requirement, description				Under the General Banking Law, banks must maintain regulatory capital of at least 8% of risk-weighted assets, net of required credit losses, as well as a paid-in capital and reserve requirement ("tire capital") of at least 3% of total assets, also net of credit losses. Regulatory capital and basic capital are calculated on the basis of the Consolidated Financial Statements. As we are the result of a merger between two predecessors with significant market shares in the Chilean market, we are currently required to maintain a minimum regulatory capital to risk-weighted assets ratio of 9.63%.Regulatory capital is defined as the aggregate of: -the paid-in capital and reserves of a bank, excluding capital attributable to foreign subsidiaries and branches or core capital; -subordinated bonds, valued at their placement price (but decreasing by 20.0% for each year during the period beginning six years before maturity), for an amount of up to 50.0% of its basic capital; -voluntary provisions for credit losses in the amount of up to 1.25% of risk-weighted assets.

The Bank evaluated those instruments with unrealized losses as of December 31, 2023 and 2022 and concluded they were not impaired. This review consisted of evaluating the economic reasons for any declines, the credit ratings of the securities’ issuers, and the Bank’s intention and ability to hold the securities until the unrealized loss is recovered. Based on this analysis, the Bank believes that there were no significant or prolonged declines nor changes in credit risk which would cause impairment in its investment portfolio, since most of the decline in fair value of these instruments was caused by market conditions which the Bank considers to be temporary. All of the instruments that have unrealized losses as of December 31, 2023 and 2022 were not in a continuing unrealized loss position for more than one year.

b.	Other financial instruments

The Bank classifies certain loans and account receivables at fair value through other comprehensive income (FVOCI), when a credit operation exceeds single client exposure under the Bank’s credit risk policy. Initially, the risk committee approves the full operation but with the condition to sell a portion of the loan in the medium term.

Additionally, the Bank includes operations that expect to sell, for which an increase of the credit risk has been identified.

This portfolio is measured at fair value, recognising the adjustment in other comprehensive income. The portfolio is assessed for impairment loss under the ECL model, same as loans at amortised cost.

i.	Loans from the Chilean Central Bank

In response to the COVID-19 pandemic, the Chilean Central Bank awarded two credit lines for banks to reinforce their liquidity: The first line of credit was the Credit Facility Conditioned to Increase of Loans (FCIC), whose objective was for banks to continue financing households and companies’ loans. The FCIC1 amounted to US$24 billion for the whole banking system and has maturities of up to 4 years and must be secured by government bonds, corporate bonds or highly rated large commercial loans as collateral. The FCIC2 amounted to US$16 billion and was available only for banks which previously disbursed FCIC1. The FCIC3 was announced in January 2021 and amounted to US$10 billion. The second credit line was the Liquidity Credit line (LCL) and was an unsecured loan facility and had maturities of up to 2 years. In addition, the LCL was limited to the aggregate amount of the liquidity reserve requirements of each bank.

The loans balances from the Chilean Central Bank by maturity are as follows:

Pension Plans [Abstract]

PENSION PLANS

NOTE 35 - PENSION PLANS

The Bank has an additional benefit available to its principal executives, consisting of a pension plan. The purpose of the pension plan is to endow the executives with funds for a better supplementary pension upon their retirement.

For this purpose, the Bank will match the voluntary contributions made by the beneficiaries for their future pensions with an equivalent contribution. The executives will be entitled to receive this benefit only when they fulfill the following conditions:

Aimed at the Bank’s management

The general requisite to apply for this benefit is that the employee must be carrying out his/her duties when turning 60 years old

The Bank will create a pension fund, with life insurance, for each beneficiary in the plan. Periodic contributions into this fund are made by the manager and matched by the Bank

The Bank will be responsible for granting the benefits directly

If the working relationship between the manager and the respective company ends, before s/he fulfills the abovementioned requirements, s/he will have no rights under this benefit plan.

In the event of the executive’s death or total or partial disability, s/he will be entitled to receive this benefit.

The Bank will make contributions to this benefit plan on the basis of mixed collective insurance policies whose beneficiary is the Bank. The life insurance company with whom such policies are executed is not an entity linked or related to the Bank or any other Santander Group company.

Plan Assets owned by the Bank at the end of 2023 totaled MCh$5,260 (MCh$6,819 in 2022).

The amount of the defined benefit plans has been quantified by the Bank, based on the following criteria:

Calculation method:

Use of the projected unit credit method which considers each working year as generating an additional amount of rights over benefits and values each unit separately. It is calculated based primarily on fund contributions, as well as other factors such as the legal annual pension limit, seniority, age and yearly income for each unit valued individually.

Assets related to the pension fund contributed by the Bank into the Seguros Euroamérica insurance company with respect to defined benefit plans are presented as net of associated commitments.

Actuarial hypothesis assumptions:

Actuarial assumptions with respect to demographic and financial variables are non-biased and mutually compatible with each other. The most significant actuarial hypotheses considered in the calculations were:

	Post-employment plans		Post-employment plans
	2023		2022
