[Grammar] the last fiscal year or just last fiscal year?

[Snappy]

In my understanding, "the" is not required before the word "last" when we refer to things that happened last week, month, year, etc.

Are the following sentences okay?

Will you show me the company's sales figures of last year?
Will you show me the company's sales figures of last fiscal year?

In my understanding, "the" is not required before the word "last" when we refer to things that happened last week, month, year, etc.

Are the following sentences okay?

Will you show me the company's sales figures of last year?
Will you show me the company's sales figures of last fiscal year?

The usual way to say the second sentence is: Will you show me the company's sales figures for the last fiscal year? You are specifying the type of year, the fiscal year rather than, for example, the school year. The first sentence would be better with "for" as well.
