Repeatedly, characteristic temporal variations in the light-element composition of >4~MeV solar energetic particles are found. In the early phase of the event, energetic ions often show high helium-to-proton ratios significantly above typical coronal values. In the later phase, typically after several hours into the event, the He/p ratio changes into a composition more resembling that of the solar corona. A survey of events with the above characteristics is performed in comparison with the LASCO coronal mass ejection list. Furthermore, the MeV ion composition is compared with observations at suprathermal energies. The systematics and implications of the findings will be discussed in the context of the current paradigm that distinguishes between impulsive and gradual solar energetic particle events.
