According to the summary of the memorandum:
“Three unmanned lunar launchings this year, together with other new evidence and further analysis, clearly indicate a continuing strong Soviet interest in lunar exploration. We still cannot state conclusively, however, that the Soviets are in a race with the US for a manned lunar landing. On balance, we have no basis for changing our earlier estimate that the chances are better than even that the Soviets will seek to accomplish a manned lunar landing ahead of or in close competition with the US. It remains possible nevertheless, that Soviet lunar objectives are less ambitious.”
