Certain companies in the Group have collective bargaining contracts which include defined benefit pension plans and other retirement benefits for substantially all of their employees. Additionally, the Group has defined benefit pension plans for certain eligible executives and employees. All pension benefits are based on salary and years of service rendered.

Under the provisions of the Mexican Labor Law, seniority premiums are payable based on salary and years of service to employees who resign or are terminated prior to reaching retirement age. Some companies in the Group have seniority premium benefits which are greater than the legal requirement. After retirement age employees are no longer eligible for seniority premiums.

Post-employment benefits are actuarially determined by using nominal assumptions and attributing the present value of all future expected benefits proportionately over each year from date of hire to age 65.

The Group used actuarial assumptions to determine the present value of defined benefit obligations, as follows:

Had the discount rate of 7.8% used by the Group in 2021 been decreased by 50 basis points, the impact on defined benefit obligation would have been an increase to Ps.3,308,348 as of December 31, 2021.

Had the discount rate of 6.6% used by the Group in 2020 been decreased by 50 basis points, the impact on defined benefit obligation would have been an increase to Ps.3,382,711 as of December 31, 2020.

The reconciliation between defined benefit obligations and post-employment benefit liability in the consolidated statements of financial position as of December 31, 2021 and 2020, is presented as follows:

Pensions and Seniority Premiums Plan Assets

The plan assets are invested according to specific investment guidelines determined by the technical committees of the pension plan and seniority premiums trusts and in accordance with actuarial computations of funding requirements. These investment guidelines require a minimum investment of 30% of the plan assets in fixed rate instruments, or mutual funds comprised of fixed rate instruments. The plan assets that are invested in mutual funds are all rated “AA” or “AAA” by at least one of the main rating agencies. These mutual funds vary in liquidity characteristics ranging from one day to one month. The investment goals of the plan assets are to preserve principal, diversify the portfolio, maintain a high degree of liquidity and credit quality, and deliver competitive returns subject to prevailing market conditions. Currently, the plan assets do not engage in the use of financial derivative instruments. The Group’s target allocation in the foreseeable future is to maintain approximately 30% in equity securities and 70% in fixed rate instruments.

The weighted average asset allocation by asset category as of December 31, 2021 and 2020, was as follows:


	2021		2020
Equity securities ⁽¹⁾	32.7	%	28.8	%
Fixed rate instruments	67.3	%	71.2	%
Total	100.0	%	100.0	%

(1)	Included within plan assets at December 31, 2021 and 2020, are shares of the Company held by the trust with a fair value of Ps.119,851 and Ps.101,690, respectively.

The weighted average expected long-term rate of return of plan assets of 7.79% and 6.59% were used in determining net periodic pension cost in 2021 and 2020, respectively. The rate used reflected an estimate of long-term future returns for the plan assets. This estimate was primarily a function of the asset classes (equities versus fixed income) in which the plan assets were invested and the analysis of past performance of these asset classes over a long period of time.

This analysis included expected long-term inflation and the risk premiums associated with equity investments and fixed income investments.

The following table summarizes the Group’s plan assets measured at fair value on a recurring basis as of December 31, 2021 and 2020:
